Nanochemistry in Action

first_imgOverall the experiments showed how a nanoscale chemical reaction of cerium compounds can increase the conductivity of the surrounding carbon nanotubes. By using nanochemistry to controllably alter the nanotubes’ electric properties, researchers may be a step closer to using nanotubes for electronics applications.“Our nano test tube chemistry allows a clean, slow and defined growth of carbon nanotubes,” said Shiozawa. “Individual chemistry events can be observed at the elemental level when materials are confined within the nano test tube. This nanochemistry process can be applied for studying the growth mechanism of carbon nanotubes. Its conceptual advance would be for any chemical reactions in general. We showed that doping of the host carbon nanotube can be varied via encapsulations and chemical reactions of molecules. This process might be applied for modulating electrical properties of a SWCNT at the nanoscale and provides for better compatibility of carbon nanotubes with electronics.”Professor Ravi Silva, Director of the Advanced Technology Institute, added, “Our results are world-leading and will tell researchers and technologists working on the next generation of nanoelectronic devices some of the fundamental issues that must be taken into account in their design. We have shown that single atoms stuck on the surface of a carbon nanotube can have a tremendous effect on its electrical characteristics. The implications are widespread because these tubes are proposed to be used as wires in nano-scale integrated circuit chips within the next decade.”The study is published in a recent issue of Physical Review Letters, and the research was sponsored by a Portfolio Partnership award by the Engineering and Physical Sciences Research Council (EPSRC), UK.More information: H.

Explore further In a recent study, a team of scientists from the UK, Austria, Germany and Japan have experimented with nano test tube chemistry by performing electron doping of carbon nanotubes using cerium compounds. Doping provides a promising means of tuning the nanotubes’ bulk electronic properties. In addition to helping scientists understand nanoscale chemistry, these experiments also highlight the potential of using nanotubes in future electronic devices.“We used nano test tube chemistry to functionalize the electronic properties of carbon nanotubes,” lead author of the study Hidetsugu Shiozawa of the University of Surrey told PhysOrg.com. “This allowed us to observe a fundamental physical phenomenon in bulk carbon nanotubes associated with a transition from semiconducting tubes to metallic.”In their experiments, the researchers sealed a combination of carbon nanotube material and cerium organometallic compounds in a Pyrex tube, and annealed them at temperatures of up to 200°C (392°F). After annealing, the researchers observed SWCNTs containing cerium molecules. Further annealing at 1000°C (1832°F) in vacuum allowed the researchers to transform the filled SWCNTs into double-walled carbon nanotubes containing cerium (Ce@DWCNT). The transmission electron micrographs show sharp lines, which are original nanotubes, inside of which are parallel lines and dark dots, which are inner tubes and cerium ions, respectively.The scientists were then able to extract electronic information from the cerium compounds in order to investigate the structures’ electronic properties. By measuring the energy of the emitted electrons using a method called resonance photoemission spectroscopy, the researchers found that the nanotube bundles had an increased density of conduction electrons after cerium doping, due to the transformation of the originally semiconducting nanotubes into metallic nanotubes.“When chemistry is performed in these nano test tubes, the reactions that occur get closer to a result of a single molecule reacting with another, instead of billions of molecules reacting with each other and with anything else we put into laboratory test tubes,” said Shiozawa. “The one-dimensionally quantized electronic states of carbon nanotubes allow specific molecules and compounds to interact, so we can monitor the encapsulated chemical reactions through the carbon nanotubes’ electronic states.” Citation: Nanochemistry in Action (2009, March 6) retrieved 18 August 2019 from https://phys.org/news/2009-03-nanochemistry-action.html (Left) An illustration of the conversion of encapsulated cerium molecules to an inner nanotube.

Researchers find soap film microchannel size tunable with electric charge

first_img Journal information: Physical Review Letters New rechargeable batteries needed: A microporous polymer is an unusually powerful supercapacitor In studying how fluids behave, scientists have found that when they move through a channel, free ions in them tend to stick to channel walls. Applying voltage to the ions causes them to move. That movement rubs the rest of the molecules causing them to move as well. The result is movement of a liquid through a channel due to an electric charge (electro-osmosis). Researchers have found that at the micro level, where the ratio of ions sticking to walls compared to the total amount of fluid is high, the process is particularly strong.In this new research, the team wondered what might happen if the channel walls were elastic. To find out, they created a soap film (essentially a bubble) between two electrodes separated by just half a centimeter. In this scenario, the soap film existed as two very thin, concentric cylinders of soapy material (water, surfactant and a small amount of potassium chloride to provide the free ions) with ions and water moving freely. Without a charge, gravity would cause the water molecules to fall towards the ground, eventually breaking the film (or popping the bubble). When given a small charge, however, the movement of the ions was sufficiently strong to keep the fluid moving throughout the film, and in some cases was actually strong enough to push it upwards. This was no surprise as other researchers had seen the same result. What was surprising however, was what happened when the voltage was increased.Prior research had suggested that increasing the voltage would cause the fluid movement rate to increase at a linear rate. Instead, they found the rate increased much faster than predicted. Upon closer inspection they found that this was due to the film becoming thicker, allowing for the movement of more liquid. This finding suggests it might be possible to create fluid micro-gates that can be fine tuned by adjusting the amount of electric charge and/or free ions, resulting in a type of micro-diode. More information: Soft Nanofluidic Transport in a Soap Film, Phys. Rev. Lett. 110, 054502 (2013) prl.aps.org/abstract/PRL/v110/i5/e054502AbstractWe investigate experimentally the electrokinetic properties of soft nanofluidic channels that consist in soap films with nanometric thickness, covered with charged surfactants. Both the electric and fluidic responses of the system are measured under an applied voltage drop along the film. The electric field is shown to induce an electro-osmotic hydrodynamic flow in the film. However, in contrast to systems confined between solid surfaces, the soft nature of the nanochannel results furthermore in a thickening of the film. This effect accordingly increases the total electro-osmotic flow rate, which behaves nonlinearly with the applied electric field. This behavior is rationalized in terms of an analogy with a Landau-Levich film withdrawn from a reservoir, with the driving velocity identified here with the electro-osmotic one.Featured on Physics Focus (Phys.org)—Researchers with Institut Lumière Matière, at the University of Lyon have found that soap film channels can be tuned using an electric charge to cause them to grow thicker or thinner on demand. In their paper published in Physical Review Letters, the team describes how they replaced a physical channel with one made of a thin soap film and found it was tunable due to its elastic walls.

Direct detection of nuclear transition in thorium229 hints at possibility of nuclear

first_img © 2016 Phys.org More information: Lars von der Wense et al. Direct detection of the 229Th nuclear clock transition, Nature (2016). DOI: 10.1038/nature17669AbstractToday’s most precise time and frequency measurements are performed with optical atomic clocks. However, it has been proposed that they could potentially be outperformed by a nuclear clock, which employs a nuclear transition instead of an atomic shell transition. There is only one known nuclear state that could serve as a nuclear clock using currently available technology, namely, the isomeric first excited state of 229Th (denoted 229mTh). Here we report the direct detection of this nuclear state, which is further confirmation of the existence of the isomer and lays the foundation for precise studies of its decay parameters. On the basis of this direct detection, the isomeric energy is constrained to between 6.3 and 18.3 electronvolts, and the half-life is found to be longer than 60 seconds for 229mTh2+. More precise determinations appear to be within reach, and would pave the way to the development of a nuclear frequency standard.Press release Journal information: Nature As Safronova notes, humans have always looked for new and better ways to keep track of time, which has led us from using the transition between night and day to the electronic transition in caesium atoms that today form the basis of atomic clocks which are capable of keeping time so precisely that they lose or gain a second only every 15 billion years. But still, scientists are not satisfied, many have suggested that creating clocks based on a nuclear transition from an excited state to a ground state, would be an order of magnitude more precise. The problem has been in figuring out how to measure such a transition—the only means possible today is to use a laser, but today’s laser are only capable of measuring the very slowest of transitions, which occurs with thorium-229—but even that has proven problematic, until now. In this new effort, the researchers report using a low-energy microchannel plate detection technique that ultimately led to electrons colliding with a phosphor screen, resulting in the generation of visible light which was captured by a camera. After extensive testing to ensure that the signals came from the decay of the thorium-229 instead of some other source, they team was ready to announce that they had found a way to detect a nuclear transition that could conceivably be used as a means for the basis of a nuclear based clock which could be as much as ten times more accurate than current atomic clocks.Such a clock Safronova, notes, could be used to test fundamental physics constants and even perhaps even dark matter, or as 3D gravity sensors or perhaps as part of an earthquake detection system.

Bones found in Romanera grave in London may be Asian

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Prior to this latest find, only one instance of the remains of a person from Asia has ever been found in a Roman era gravesite, suggesting there was little to no immigration between people in Asia and Europe during the Roman Empire, despite the existence of the Silk Road. The prior find was a skeleton of a man of East Asian ancestry discovered in a grave in Vagnari in Italy six years ago—and unlike the tests done with the newly found skeletons, his ancestry was proven by DNA testing.In this new finding, the two skeletons were part of a group of 22 skeletal remains found buried in an ancient Roman grave in Southwark, a London borough. The bones have been dated back to a period between the second and fourth centuries, a time during which the Roman Empire was still going strong. The researchers have thus far analyzed oxygen isotopes from the teeth and carbon and nitrogen isotopes from the bones—doing so has helped to reveal the eating and drinking habits of the people buried there, which showed that many of them were from places other than London.They also conducted statistical modeling of the skulls and teeth—differences have been attributed to people of different ancestries. It is the same technology used by forensic experts to establish the ancestry of decomposed skeletal remains. It was this testing that suggested that two of the skeletons were likely of Asian descent—and that four others were likely of North African descent. The researchers acknowledge that the method is not nearly as clear-cut as DNA testing, and in this case, it was even less so because many of the bones used in the analysis were fragmented. To actually prove that the bones had Asian ancestry, they will have to find some DNA to test. (Phys.org)—A small team of researchers with Durham University, the Museum of London and the British Geological Survey has tentatively established that two skeletons found in a Roman-era grave in London are of Asian origin. In their paper published in the Journal of Archaeological Science, the team describes the skeletons, the tests they conducted on them and why they believe they may be of Asian origin.

DOI: 10.1016/j.jas.2016.07.016AbstractThis study investigated the ancestry, childhood residency and diet of 22 individuals buried at an A.D. 2nd and 4th century cemetery at Lant Street, in the southern burial area of Roman London. The possible presence of migrants was investigated using macromorphoscopics to assess ancestry, carbon and nitrogen isotopes to study diet, and oxygen isotopes to examine migration. Diets were found to be primarily C3-based with limited input of aquatic resources, in contrast to some other populations in Roman Britain and proximity to the River Thames. The skeletal morphology showed the likely African ancestry of four individuals, and Asian ancestry of two individuals, with oxygen isotopes indicating a circum-Mediterranean origin for five individuals. Our data suggests that the population of the southern suburb had an ongoing connection with immigrants, especially those from the southern Mediterranean.

Revised Met forecast sparks drought fears

first_imgWhile releasing the second stage long range forecast of monsoon, Union Minister for Earth Sciences Harsh Vardhan said that the rain will be 88 per cent instead of 93 per cent of earlier forecast.In its current update, IMD says there is about 90 per cent probability of El Niño conditions prevailing during the south-west monsoon season. El Niño conditions are likely to strengthen further and reach moderate strength during the monsoon season. Also Read – Need to understand why law graduate’s natural choice is not legal profession: CJI “For 2015, the IMD’s prediction of an overall 93 per cent probability of a weak monsoon is a worrying cause for all of us. The onset has been delayed by a week already and there is no certainty on when the monsoon will arrive,” Vardhan said, while dedicating the country’s high performance computing (HPC) facility – Bhaskara.However, talking to Millennium Post, Union Agriculture Minister Radha Mohan Singh said: “There is nothing to panic about it. The government is ready to tackle the drought-like situation if it happens due to deficient rain.” Also Read – Health remains key challenge in India’s development: Kovind“Given the fact that about 60 per cent of the country’s cultivable land is rain-fed and low rain will directly hit the farm sector.

TMC continues to add glitz and glamour to poll arena

first_imgKolkata: Continuing with her penchant for bringing in silver screen personalities to politics, Trinamool Congress supremo Mamata Banerjee has fielded five film stars, including two greenhorns, for the coming Lok Sabha elections. In the 2014 general elections, Banerjee had fielded the same number of cinestars and all the five had won. It was Banerjee who had in 2009 started the practice of fielding people from the glamour world in West Bengal elections, which was considered to be the forte of southern states. Also Read – Bose & Gandhi: More similar than apart, says Sugata Bose Of the 42 Lok Sabha constituencies in West Bengal, the TMC had won 19 seats in 2009 and 34 in 2014. The party also adds a dash of colour to major public meetings, where celebrities from the film and television world assemble. Fielding of Mimi Chakraborty, a popular actress in Bengali cinema and a political greenhorn, from the prestigious Jadavpur constituency for the 2019 elections has come as a surprise to many. It was from this constituency in the city that Mamata Banerjee had burst into electoral politics in 1984 as a young Congress candidate, by handing a stunning defeat to incumbent and towering Somnath Chatterjee of the CPI(M). Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: Mamata Sugata Bose, a professor of Oceanic History and Affairs at the Harvard University held the seat as a TMC MP in the outgoing 16th Lok Sabha. Reportedly, he has not been given permission by the university to contest the elections this time. Another political greenhorn and Bengali film actor Nusrat Jahan has been fielded from Basirhat in North 24 Parganas district, a seat now held by TMC’s Idris Ali. Banerjee has said Ali will contest in an Assembly by-election. Apart from these two, actors and sitting MPs Deepak Adhikari, popularly known as Dev, Satabdi Roy and Munmum Sen will also contest. While Dev and Roy would seek re-election from Ghatal and Birbhum seats respectively, Sen has been shifted from Bankura to Asansol, which was won by singer-turned-politician Babul Supriyo of the BJP. The TMC has dropped sitting MPs Tapas Pal and Sandhya Roy, well-known film stars of yesteryears. Pal had been arrested by the CBI in December 2016 in connection with the Rose Valley chitfund scam and is at present out on bail. Pal and Satabdi Roy are two-time MPs of the TMC, both having earlier won in the 2009 elections. The TMC supremo had also made Bollywood star Mithun Chakraborty a Rajya Sabha MP. But he had resigned in December 2016 citing ill health. The trend of cine stars joining electoral politics has been a regular affair in the southern states, with former Tamil Nadu chief minister M G Ramachandran as the pioneer and Rajnikanth and Kamal Haasan being the latest entrants. Andhra Pradesh is another state where film stars enjoy cult status and have made serious forays into politics, with N T Rama Rao having become chief minister of the state. In other parts of the country, film stars like Raj Babbar, Hema Malini, Vinod Khanna have been in politics and even mega star Amitabh Bachchan had a short tryst with it. Film stars have, however, generally stayed away from electoral politics in West Bengal, where it has traditionally been viewed as a forte of those who grow from the ranks, barring one or two exceptions. The so-called glass ceiling was broken in 2009 when Satabdi Roy and Tapas Pal, both of whom were doing films regularly then, were fielded by the TMC chief and won. The BJP has also brought in film personalities and those associated with it in West Bengal politics. Babul Supriyo, a playback singer who also dabbled in film acting, was one of the two BJP candidates who won in the 2014 Lok Sabha elections from West Bengal. He was also made a minister of state. Actor Roopa Ganguly, who achieved national fame for her portrayal of the role of Draupadi in mega teleserial Mahabharat, is a Rajya Sabha MP of the BJP.last_img read more

Make summers trendy with prints

first_imgIn this fashion savvy world, most trends keep changing with time, but there are a few items in your wardrobe that can never be replaced – including denims, LBDs, prints. And, if we particularly talk about ‘prints’, they always stay with fashion and never fail to make a statement.No doubt, print individually is the safest style to opt for, but when styling it with other print (print on print trend), one really needs to be careful. According to style experts, pairing different patterns require an artistic vision, as it involves a lot of risk. That is why a lot of people are scared to experiment with such outfits. Though there are no listed rules to explore this trend, just make sure that they compliment one another. Also Read – Add new books to your shelf Also, summer is definitely the best season to flaunt fun print-on-print outfits. So, let’s see what all we can try to make our outfits stand out: Play safe and go for the most basic and universal print patterns like animal prints, stripes, geometrical patterns, polka dots, floral, checkered, etc. The most essential thing while experimenting with prints is to stay in the same colour family. As long as the prints have at least one colour in common, you can use contrasting colours. Match colours, not prints! Also Read – Over 2 hours screen time daily will make your kids impulsive If you want to make a bold choice of mixed pattern outfits, you have to be very careful with what you choose. To start with, keep in mind that some patterns don’t look good with one another. And, the simplest trick is to mix stripes with floral print. If you want to flaunt a mixed print outfit in a softer version you can add printed shoes, bags, and accessories to your regular outfit. One more way to don print this season is to pick pieces in vibrant colours. Eye-catching patterns in vivid colours will make the boldest outfits. These outfits are hard to miss and will surely catch eyeballs wherever you show up. Try the same print but in different sizes. One thing you can note is that graphic prints always match with each other. In this regard, you can also play with florals while matching your outfits; just go with bigger, more prominent ones. Though there is nothing wrong with combining prints from various categories, try to be subtle and make sure you don’t go over two prints at a time. Else, it will end up in a messy look and surely, that is not what we want, right? Speaking of the rules, the most important point is to be confident and comfortable in what you wear. So this Summer, pick the best prints, revamp your wardrobe and give major fashion goals to people around you.last_img read more

Sobhandeb points finger at Centre for failing to make Katwa power project

first_imgKolkata: State Power minister Sobhandeb Chattopadhyay said during his Budget speech in the Assembly on Monday that the Centre has failed to make the Katwa power project operational despite the state government providing land for the same.Chattopadhyay said it could not be made operational due to failure of the Centre’s policy. Chief Minister Mamata Banerjee had taken initiative to arrange land for the 1,320 MW Katwa power project, but the National Thermal Power Corporation (NTPC) is yet to take any major step in this regard. Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: MamataEven the officers who were posted there have been withdrawn, the minister added, who visited the spot last month to take a stock of the overall situation. During his budget speech, the minister also complained about the Centre’s apathy to provide clearance for various power projects. He said that the state government had written to the Centre to issue clearance for the various coalmines including those in Barjora I & II, but no steps have been taken in this regard yet. Also Read – Lightning kills 8, injures 16 in stateThe state government has also been awaiting clearance for mining in the Deocha Pachami coal block in Birbhum, which is one of the biggest reserves in Asia. While responding to a query of an opposition MLA on the price of electricity, the minister said that since March 2017, there has been no price hike despite recommendation by the Central Electricity Regulatory Commission to raise the price. The state government has been giving a subsidy of Rs 1,000 crore to compensate the loss. The minister also said that under the ‘Aloshree’ project, a brainchild of Chief Minister Mamata Banerjee, the department has set a target of setting up 1,000 solar plants on the rooftops of school buildings. Giving a detailed account of the power scenario in the state, the minister said demand has gone up by 16 percent in the state. “In the last seven and half years, the number of industrial consumers has gone up by 39 percent. New electricity connections will be given to 1.83 lakh new domestic consumers, 16,663 new commercial consumers, 427 industries and 6,969 agricultural connections. There had been around 85 lakh consumers when the present government came to power. Now the number of consumers in the state has gone up to 1.91 crore,” he said. The Chief Minister instructed the Power department to ensure that all the interior villages have been brought under electricity coverage and rural electrification works have been completed. The department has also ensured quality power to various districts.last_img read more

John Lennons Biggest Fear and the One Time he Complimented a Paul

first_imgSometimes the biggest talents are the ones most lacking in confidence. Take the Beatles and John Lennon for example. They blazed a trail across the world stage between 1960 – 1970, yet for their most attention-grabbing member fame was a source of anxiety. Speaking to 60 Minutes, Sir Paul McCartney told interviewer Sharyn Alfonsi that Lennon once confided in him over the single biggest fear he had and the doubt he was having about his public persona.Despite being much-admired by an army of aficionados, Lennon told McCartney “I’m worried about how people are going to remember me.”Paul McCartney performing on April 19, 2014 at Estadio Centenario in Montevideo, Uruguay. Photo by Jimmy Baikovicius CC BY-SA 2.0Alfonsi and viewers saw that McCartney was clearly moved by the experience, even decades on. He “recalls trying to console him by saying, ‘John, listen to me, look at me. You’re going to be remembered as one of the greatest people.’ I’m getting choked up. I said… ‘Cause you are, you’re fantastic.’”It may sound surprising that a performer of Lennon’s stature was quite so concerned about his legacy. However for McCartney it goes with the territory.Paul McCartney and John Lennon, 1964.“I think if you care about what you’re doing, if you really want to get it right, then you’ve got to deal with insecurities,” he says in the interview. “It’s what makes it right. It doesn’t matter how elevated you get or your reputation gets, you still worry about things.”Maybe Lennon’s insecurity stemmed from his complex personality. As noted in a review of Being John Lennon: A Restless Life by Ray Connolly in The Washington Post this month, “Connolly’s account of Lennon, whom he calls ‘a labyrinth of contradictions,’ emphasizes his sardonic, rebellious, self-inventing qualities.”John Lennon and Yoko Ono. Photo by Jack Mitchell CC BY-SA 4.0Lennon was clearly looking to be more than just another rock star, as his association with Yoko Ono among other developments proved.Connolly “recalls, for example, Lennon saying that his youthful ambition was ‘to write Alice in Wonderland and be Elvis Presley’ — as succinct and prophetic a description of the Beatles’ career as one could imagine.”McCartney, Harrison, Swedish pop singer Lill-Babs and Lennon on the set of the Swedish television show Drop-In, 30 October 1963.He was arguably a man of such high ambition that he would always be subject to self doubt. But he went on achieve titanic feats in rock and pop music, spanning skiffle, psychedelia and the peace movement.One of the bedrocks of his life was his long-standing friendship with McCartney, with whom he wrote such classics as “Ticket to Ride” and “Help!” (both 1965).Not that it was the smoothest of partnerships. Like with any creative pairing, the road could be rocky. The pair have contradicted each other over who contributed what.And McCartney revealed to 60 Minutes that his pal wasn’t exactly generous when it came to dishing out the praise.Paul McCartney. Photo by Oli Gill CC BY-SA 2.0In contrast to McCartney’s reassurances to Lennon, Paul revealed that there was only one single occasion where Lennon praised McCartney’s songwriting prowess. The track was “Here, There & Everywhere”, as featured on the band’s Revolver album of 1966.“That’s a really good song, lad,” Lennon reportedly said. “I love that song.”John Lennon. Photo by Roy Kerwood CC BY 2.5Tragically Lennon wasn’t able to reflect too long on his contribution to global music. On December 8, 1980, at the age of just 40, he was gunned down in New York by Mark David Chapman.As mentioned on the History.com website, “Chapman was a troubled individual who was obsessed with… various celebrities… he decided that Lennon was a phony and, while listening to Beatles tapes, Chapman decided to plan his murder.”A request for parole, Chapman’s 10th, was refused late last year. It was a horrifying end to a successful life. That said, it hasn’t diminished the impact of Lennon’s work in the close to four decades since his assassination.Read another story from us: The Psychedelic Revolution of the BeatlesAs long as family, friends like McCartney, and millions of fans are there to speak of him with love then he’ll always be remembered as one of the all time greats.last_img read more

WATCH Jackie Robinson dominates overmatched competition in incredible UCLA football highlight package

first_img Advertisement Jackie Robinson is best known for breaking the Major League color barrier with the Brooklyn Dodgers, but he was also a four sport star at UCLA, including starring on the football team at running back.As superior as Robinson was athletically against most of his all-white competition in baseball, he was also on another level on the gridiron. His highlights are sparse, but an awesomely edited 2 plus minute video of Robinson as a Bruin was recently posted on Twitter shows how dominate he would have been had the timing been right in the NFL. Robinson runs wild, gets some picks at defensive back and even catches a bomb at the end.Watch Robinson doing work in 1939:Watched thousands of hours of old football film past 5 yrs. Here’s video I slapped together of the Reggie Bush of the leather helmet era. His name? Jackie Robinson. Yep, same guy. Last TD is vs. Chicago Bears.

Hosted Exchange Eliminates Server Admin Headaches

first_img Attend this free webinar and learn how you can maximize efficiency while getting the most critical things done right. February 26, 2009 4 min read Microsoft Exchange can help businesses manage the e-mail and collaboration services their employees use. However, Exchange is not the easiest Microsoft app to install and keep in good running order, particularly for a small business without a dedicated IT department.While I believe Exchange 2007 is a little easier to set up than Exchange 2003, the newer version is available only as a 64-bit application; you may need to upgrade your server hardware to run the new Exchange.The good news is that you don’t need to install Exchange on your own server to gain its benefits. You can sidestep all the hassles of hiring an IT pro, buying and installing the software, ensuring 64-bit hardware compatibility, and tackling maintenance issues if you outsource Exchange provisioning to an online hosting service.Hosted Microsoft ExchangeIt’s worth noting that Exchange isn’t nearly as ubiquitous as POP e-mail, and not every Internet host offers Exchange services. A growing number of hosts have added Exchange to their menu of services, though. Generally the cost is pretty affordable to a small business: Basic Exchange hosted services range from $10 to 15 per month, per employee. Optional extras, such as additional mailbox storage and message archiving, will bump up the tab.Selecting a service also involves a few other considerations that depend on your business’s requirements. For example, antispam service provided at the Exchange server is more efficient than at the Outlook e-mail client level, since users don’t need to waste time downloading unwanted messages.Do you want to help mobile employees keep in touch easily? If so, check out hosted services that also offer e-mail integration with smart phones such as RIM’s BlackBerry and Apple’s iPhone.Do you need collaboration capabilities, such as document sharing? Look for a service that also provides hosted Microsoft SharePoint.Intermedia Exchange HostingFew Exchange hosts can match the experience and ancillary offerings of Intermedia. The company has provided Exchange hosting since 2000, and it presents a variety of auxiliary services (some at extra cost), including antispam, mobile message integration, and SharePoint.Intermedia uses HostPilot, a proprietary control panel, to guide you in setting up its services. I like the way HostPilot keeps you on track for configuring Exchange through step-by-step directions. Online help, including FAQs and getting-started videos, along with e-mail and telephone support, is readily available.Completing the online configuration for ten users will probably take a couple of hours for an administrator to perform, though that depends on the options you select.Though I like Intermedia’s Exchange hosting, you have many alternative providers to choose from. If you’re satisfied with the service your Web host provides, see if the company also offers Exchange hosting; at the very least, sticking with your Web host will simplify domain setup.Hosted Exchange CostsIntermedia offers a number of hosting plans, along with optional add-ons. A Small Business Exchange plan for ten users (including 40GB total mailbox storage) is $125 per month. Antivirus, antispam, and SharePoint (50MB storage) are included in the monthly fee. Each user receives a free download of Outlook 2007. Additional mailboxes with 1GB storage cost $12 per month.Some additional services include mobile support, such as BlackBerry Enterprise Server ($10 per user per month, plus $40 setup) and ActiveSync for iPhone and Windows Mobile devices ($3 per user per month). MessageMirror e-mail archiving costs $49 per month for 2GB storage plus a $100 one-time setup charge.Is Hosted Exchange Right for You?If you want to outsource Exchange, you should consider several factors, such as cost, convenience, and flexibility. For a small business without an IT professional on staff, the all-in cost of outsourcing Exchange can save thousands in comparison with the alternative of purchasing hardware, licensing software, and hiring someone–even a consultant–to manage it all. Moreover, hosting providers can easily upscale your Exchange server as your business grows (or downsize it if your business shrinks) without interrupting your service.Though outsourcing Exchange is convenient, it comes at the potential loss of some flexibility in configuring it and installing add-ons appropriate for your business requirements. A business with more than 100 users, particularly one with more-complex requirements, may find that providing Exchange services through internal resources makes more sense.Richard Morochove is an IT consultant and writer.
