Scientists discover water is sticky on a small scale

Posted On Aug 31 2019 by

first_img Explore further When water vapor condenses in a nano-sized space between two surfaces, the liquid behaves more like solid ice than liquid water, even at room temperature. This solidification causes water to exert such a strong friction force that it “acts like a glue,” according to a new study. If you’ve ever thought about ice skating on a dry floor – or anywhere besides a sheet of ice – you can easily imagine how you’d ruin your blades and not get very far. Ice skating – like many processes involving moving parts – requires water acting as a lubricant between the blades and the solid ice, reducing friction and keeping the sliding surfaces apart from each other. Now imagine you’re five nanometers tall and want to go ice skating, or that you want to build a nano-sized sliding element using water as a lubricant. Scientists who have recently been experimenting with tiny moving devices have run into problems due to stiction (static friction) forces between moving parts.“Micro- and nano-electromechanical systems (MEMS and NEMS) have tiny moving parts typically etched out of silicon,” said J. Frenken, coauthor with K. Jinesh of a recent Physical Review Letter, to PhysOrg.com. “Using special tricks such as under-etching, intricate structures can be formed with cogwheels, hinges, bending arms and sliding elements.” However, mechanical systems on the micro and nano scales endure much greater friction than their macroscopic counterparts.“Many of the designs for such miniature devices are useless in practice because the parts either don’t move at all anymore or they move with very high friction, which leads to excessive wear,” said Frenken. “After a short time, this wear destroys the device. One could state that many MEMS devices work in ‘self-destruct’ mode.”Jinesh and Frenken explain that the reason for these lube problems is that, on the nanoscale, water ceases to be wet and slippery and instead becomes solid and sticky. By studying the atomic and molecular details of water and the surfaces sandwiching the water, the scientists found condensed water is immediately converted into ice, acting more like a glue than a lubricant. This finding contrasts previous studies, which suggested that water acts like a lubricant down to the nanoscale.“In many of these MEMS and NEMS structures, there are elements that are either touching each other or close to touching each other,” said Frenken. “At the locations where two objects approach each other within a very small distance, water from the air tends to condense. This capillary condensation strongly pulls the (nearly) touching objects into intimate contact. To avoid friction and wear, these elements need to be lubricated with a liquid that would remain slippery down to the nanoscale – actually, the lubricant should become even more slippery than it is on a macroscopic scale.” Keep Cool to Reduce Friction,” Suggests a New Study of Nanoscale Water Condensation This document is subject to copyright.

Scientists have found that – unlike on the macro scale – the “liquid” acts more akin to a glue-like solid at room temperature, creating excessive friction that disables many tiny mechanical devices. Image Credit: J. Frenken and K. Jinesh. In their experiment, the scientists built a friction force microscope, which consists of a hydrophilic tungsten tip scanning back and forth across a hydrophobic graphite surface. In extremely dry conditions, the tip demonstrated expected “stick-slip motion,” meaning it would generally move evenly, while occasionally slipping ahead at regular intervals.At higher humidities (relative humidity greater than 10%), however, the scientists did not observe this motion due to water vapor condensing in the capillary between the tip and surface. The water exerts an elastic force on the tip, and as the tip moves, the water stays connected with it, appearing to stretch across the surface. (See above image.)The static stress and regular structure of the condensate makes the scientists conclude that the condensate acts like a solid. The team observed the tip “write” a stripe of water up to 250 nanometers, which lasted for up to two seconds and beyond the point where the tip scans above the condensate.“Although in many cases, water acting as a glue on the nanoscale is a nuisance, there are also situations where one can take advantage of the stickiness on this small scale,” said Frenken. “On a macroscopic scale, we all know how dental prostheses that can stay in place via the action of bridging water. In this case, however, the water is still completely liquid because of the thickness of the water layers. In the laboratory, we often use capillary condensation to pick up light objects, simply touching a small object with a thin wire, instead of using tweezers. A capillary neck forms between the object and the wire, gluing the two together.” This “nuisance,” then, may lead to more useful applications, in addition to the problem it identified.Citation: Jinesh, K.

Physicists build quantum amplifier with single artificial atom

Posted On Aug 31 2019 by

Citation: Physicists build quantum amplifier with single artificial atom (2010, May 25) retrieved 18 August 2019 from https://phys.org/news/2010-05-physicists-quantum-amplifier-artificial-atom.html As a device that uses quantum effects to amplify a signal, a quantum amplifier comes in many different forms. Perhaps the most well-known example is the laser, which uses the process of stimulated emission to emit photons from optically stimulated atoms. Like most quantum amplifiers, lasers use intra-atomic transitions with many atoms (or molecules) to achieve signal amplification, and the transition frequencies are not easily tunable.One way to realize a quantum amplifier that is tunable and fully controllable is to create a system that uses only a single atom or molecule. However, single-atom quantum amplifiers have so far been very difficult to realize due to the fact that natural atoms can only be weakly coupled to the electromagnetic waves that they must amplify. Now, researchers O.V. Astafiev and coauthors from NEC Nano Electronics Research Laboratories and RIKEN Advanced Science Institute, both in Ibaraki, Japan, have found a way to overcome this difficulty. In their new study, the researchers have demonstrated how a single artificial atom can be strongly coupled to the electromagnetic modes of open one-dimensional space, resulting in tunable and controllable electromagnetic wave amplification. The quantum amplification is based on the ability to pump the three-state artificial atom from its ground state to the higher of its two excited states. To do this, the researchers applied microwave fields at a specific pumping frequency that propagated along a one-dimensional transmission line toward the point-like atom. The photons induced spontaneous emission from the atom, causing it to generate a scattered wave at a specific frequency, amplifying the overall signal. “The key process is the preparation of population inversion (same as in lasers),” coauthor Abdufarrukh Abdumalikov from RIKEN told PhysOrg.com. “Our atom has three discrete energy levels. We apply a microwave which excites it from the ground state to the second excited state. From the latter the atom relaxes partly to ground state and partly to first excited state. When the population of the first excited state is larger than that of the ground state we have a population inversion. Then we apply another microwave signal which we would like to amplify. It should be in resonance with the ground state – first excited state transition. It stimulates this transition and the atom emits a photon which adds up to the signal. The principle is the same as in lasers.”The researchers calculated the maximal gain to be about 1.09, corresponding to an average of 109 emitted photons for every 100 incident photons. Abdumalikov explained that the maximum theoretical gain is 1.125, or 112.5 emitted photons for every 100 incident photons. Overall, the amplification by a single artificial atom provides an example of an elementary quantum amplifier, which could be used as a building block for large-scale, tunable quantum amplifiers for various applications. In addition, the demonstration of single-atom quantum amplification could open up possibilities for developing new types of on-chip quantum amplifiers and other quantum devices, which could reveal novel quantum optical phenomena due to the devices’ strong coupling, tunability and controllability. “This is the first work of this kind,” Abdumalikov said. “If we use many atoms we can obtain larger gain. Such amplifiers can be used in other research fields where low amplifier noise is needed. One such research field is an on-chip version of cavity quantum electrodynamics (QED) that is circuit QED.”last_img read more


Broadcom will ship 80211ac products in 2012

Posted On Aug 31 2019 by

first_img(PhysOrg.com) — Broadcom is highlighting a second coming of Wi-Fi in the name of the new IEEE standard 802.11ac, with this week’s announcement that its products based on the nascent standard will be ready for shipping in the second half of next year. The IEEE 802.11ac is a wireless standard of 802.11 under development. Image: Wikipedia. Wireless network service will be strengthened in three ways: in speed, longer range and battery efficiency. Broadcom provides system-on-a-chip and software solutions. Those who use Broadcom products are computing and networking equipment, digital entertainment, broadband-access, and mobile device manufacturers.At a media event in San Francisco this week, the company executive who talked about Broadcom’s push into 802.11ac also spoke on why the technology was advantageous. Rahul Patel, the company’s vice president of mobile and wireless, said the new version can operate at a speed of as much as 1.3 gigabits per second. The 802.11ac is also being singled out as using the less crowded 5Ghz band, which will be less prone to interference.As for battery advantages, since the speed is faster, it will take less time for the client to work to transmit and receive data compared with the 802.11n client.The new version offers longer range and improved wall penetration , adding up to better home service. Patel said the new speeds will make it ideal “plumbing” for the Internet-connected home. Improved connectedness will come none too soon considering consumer expectations with newer consumer electronic products. Patel said consumers will need faster Wi-Fi soon, to leverage features and functions of home technology devices such as being able to send multiple streams of video to their TVs. More devices than ever are competing for wireless connections in the home. According to a new consumer poll by JZ Analytics, nearly four times as many respondents have six or more wireless devices today than two years ago.The roadmap for the new standard, meanwhile, is populated with decisive stops along the way before full ratification of the standard. The Wi-Fi Alliance is holding its first 802.11ac compatibility testing plug-fest in the second quarter of next year. The event will lead to hardware interoperability. Existing hardware will be able to upgrade for any late changes to the standard via a firmware update This was the same procedure that was followed for 802.11n hardware, say observers.According to an IEEE industry perspective on the topic earlier this year, 802.11ac marks another milestone in wireless LAN throughputs. Since the adoption of the first 802.11 standard in 1997, there has been a steady and exponential growth in the maximum available data rate, said the article, authored by Qualcomm’s Richard Van Nee. The 802.11ac task group began work on the amendment to achieve aggregate throughputs beyond 1 Gb/s in the 5 GHz band. The 802.11ac standard will in turn represent a significant push of wireless LAN throughputs over the gigabit-per-second barrier. © 2011 PhysOrg.com NTT demos 802.11ac – next generation high-speed WiFicenter_img Citation: Broadcom will ship 802.11ac products in 2012 (2011, December 10) retrieved 18 August 2019 from https://phys.org/news/2011-12-broadcom-ship-80211ac-products.html This document is subject to copyright.

A new portable device to detect marijuana use almost right away

Posted On Aug 31 2019 by

first_img(Phys.org)—California based Hound Labs Inc. is claiming to have made a breakthrough in the rush to develop a portable device capable of detecting THC, the active ingredient in marijuana, in the breath of someone that has recently smoked a substance containing the chemical. They claim also that their device will soon be small enough for use by law enforcement to remove impaired drivers from the road. This document is subject to copyright. 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. Testing for secondhand marijuana exposure Several states in the U.S. have legalized recreational marijuana use, and even more have allowed it for medicinal use. This trend has law enforcement on edge as there is currently no roadside test that can detect THC use by a driver in real time—instead, if such use is suspected, police officers must take blood or urine samples that can take days to deliver an answer—that makes it difficult to arrest a driver on the spot, which means in some cases, letting them go to continue driving under the influence. Making things even more challenging is that not enough research has been done by scientists to find out how much THC in the body causes impaired driving—states have set different levels, and some have instituted a zero-level tolerance policy.In this new announcement, Hound Labs claims it has developed a device that is capable of detecting minute levels (below 500 picograms) of THC in the breath, which the company also claims is the only way to differentiate between heavy marijuana users who maintain high levels of THC in their bodies even hours or days after use, and those who have recently smoked it, in whatever form. Mike Lynn CEO and co-founder of the company is a practicing emergency medicine physician who has presumably witnessed the tragic consequences of people driving after smoking the drug and is looking to put a stop to it.As part of their announcement, Hound Labs says that it is working with scientists from academic institutions, law enforcement agencies and other researchers and expects to have a product small enough for a police officer to carry and use by the end of next year. They note also that the device will also work as an alcohol breathalyzer and should cost approximately the same as current breathalyzers.

Credit: Helen Deeks, in collaboration with Interactive Scientific Ltd, under CC BY-ND 4.0. © 2018 Phys.org For many years, chemistry students have been taught to manipulate physical models depicting molecules as a means of learning how they work. The researchers note that such models are not up to the task of showing how molecules work dynamically—they cannot show movement or the flexibility of molecules, which leaves students having to imagine how they might look. In more recent years, computer applications that allow students to watch and even manipulate molecules onscreen have led to improvements in teaching techniques. But, as the researchers also note, such apps that generally make use of touch screens still lack the required hands-on approach. To improve on such applications, the researchers have created a VR system that is able to show complex molecules as they exist in a 3-D space. And even better, users are able to physically manipulate the molecules to learn more about their properties.With their new system, the researchers point out, users are able to achieve co-location, which they describe as a phenomenon in which interactions in an actual 3-D physical space align with interactions in a simulated 3-D environment. Their system is cloud-based, which means the data used in the simulations can be constantly updated and improved, even as the system is being used.

Users use wireless controllers that behave like tweezers, allowing them to grab molecules and their parts.To test their system, the researchers asked 32 volunteers to carry out three different tasks: manipulating a methane molecule through a carbon nanotube, manipulating an organic helicene molecule to change its rotation, and finally, to tie a knot in a polypeptide. They report that most of the volunteers, none of whom had ever used a VR system before, were able to use the system to some degree. Other less rigorous testing showed the system capable of doing things like allowing two people to toss a molecular buckyball back and forth across a real room. The researchers also report that the volunteers reported preferring the VR system over other applications, such as touchscreens.

Sampling molecular conformations and dynamics in a multiuser virtual reality framework, Science Advances (2018). DOI: 10.1126/sciadv.aat2731AbstractWe describe a framework for interactive molecular dynamics in a multiuser virtual reality (VR) environment, combining rigorous cloud-mounted atomistic physics simulations with commodity VR hardware, which we have made accessible to readers (see isci.itch.io/nsb-imd). It allows users to visualize and sample, with atomic-level precision, the structures and dynamics of complex molecular structures “on the fly” and to interact with other users in the same virtual environment. A series of controlled studies, in which participants were tasked with a range of molecular manipulation goals (threading methane through a nanotube, changing helical screw sense, and tying a protein knot), quantitatively demonstrate that users within the interactive VR environment can complete sophisticated molecular modeling tasks more quickly than they can using conventional interfaces, especially for molecular pathways and structural transitions whose conformational choreographies are intrinsically three-dimensional. This framework should accelerate progress in nanoscale molecular engineering areas including conformational mapping, drug development, synthetic biology, and catalyst design. More broadly, our findings highlight the potential of VR in scientific domains where three-dimensional dynamics matter, spanning research and education.Anybody wishing to try out the tasks described in the paper can download the software at https://isci.itch.io/nsb-imd, and launch their own cloud-hosted session.

first_imgNearly 90 per cent of people suffer from damaged knee joints by the age of 60-65 years, orthopedicians have said, adding that in majority of the cases the condition can be prevented by a proper lifestyle and food habits.According to doctors, 80 per cent of the people in urban India suffer from Vitamin D deficiency, which is the sole reason behind decreasing the bone mass density, leading to the increase of osteoporosis.Health organisations estimate that in 2014, a total of 50 million people across India are reported to be either osteoporotic or with low bone mass density. “In our country, joint and back pains are considered as part of the normal aging process. Therefore, instead of dealing with such problem seriously people prefer to go for quick fixes like analgesics or some pain relieving balms.  “Such temporary solutions just further worsen the bone and joint conditions,” L.

QRTs falter in sixth phase due to lack of state police officials

Posted On Aug 31 2019 by

first_imgKolkata: The presence of the quick response teams (QRTs) was allegedly not felt properly in the sixth phase of elections on Sunday, when eight Lok Sabha constituencies of Bengal went to polls.In previous phases, the QRTs had moved quickly to the areas where incidents of clashes were reported. But in the sixth phase, QRTs were not as quick in their movement. Various political party leaders alleged that the QRTs failed to turn up on time when there were incidents of violence in any of the eight constituencies. In previous phases of elections, the QRTs were led by state police officers as they were well acquainted with the locations of the polling booths. Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: MamataAfter some allegations surfaced against the state police force, the Election Commission tried to adopt a separate method to conduct the elections in a free and fair manner. Special Police Observer Vivek Dubey had decided to deploy Central Force officials to lead the QRTs, keeping the state police at bay. The QRTs had faced difficulties in identifying the polling booths where the clashes were reported from, as the Central Force commandants who were supposed to give them directions had no idea about the geographical locations of the polling booths. Most of the Central Force commandants were from other states. Also Read – Lightning kills 8, injures 16 in stateAs a result of this, clashes broke out outside various polling booths and the trouble could not be quelled in time. Keeping in mind the geographical locations of the districts which were once infested with Maoists, the Election Commission decided to deploy two QRTs in each police station area. Each team comprised eight jawans. There were around 547 QRTs in the sixth phase of elections and 108 additional QRTs which were led by ad hoc commandants. According to sources in the office of the Chief Electoral Officer (CEO), the election officials in the state were not convinced with the idea of deploying Central Force commandants as the head of each QRT. The Election Commission has already submitted a report to the Election Commission of India in Delhi in this regard.last_img read more

Even though Mayfield has received the lion’s share of rookie hype, Colin has been more impressed with Jackson’s total command of the offense, freakish athleticism, and his head down demeanor.Mayfield has become an unquestioned star in his first year in the NFL, but he threw three picks again the Ravens while Jackson made the big plays to win the game and it’s Baltimore who’s headed to the playoffs.last_img read more

Subscribe » Enroll Now for Free January 25, 2011 Slideshow: 10 New iPad Productivity AppsIt turns out neither your smartphone nor your laptop should be jealous of your sleek new iPad. But those big, old three-ring binders that have always held performance reports and sales charts? Well, their days are numbered.Tablets such as the Apple iPad, Samsung Galaxy and Dell Streak are having a surprising effect at the office.”It’s much better than a binder,” says Sanju Bansal, COO of MicroStrategy, a Vienna, Va., company that develops business intelligence software for the iPad and other devices. MicroStrategy bought iPads for 1,370 of its 2,000 employees. “It’s better than having to go through 50 to 100 sheets of paper in a binder. You get full access to information and can share it more quickly.”A laptop can do roughly the same thing, but tablets may be more culturally accepted in the workplace. “There’s something very human about the tablet that isn’t human about the laptop,” Bansal says. “When you open a laptop in a meeting, it’s like you are erecting a cultural barrier between yourself and others. Tablets already have the cultural acceptance of paper.”MicroStrategy is seeing its customers adopt the iPad initially at the executive levels before it trickles down. Bansal tells of a retailer equipping its store managers with iPads to keep them on the move and a hospitality company that uses them to help hotel managers get out from behind their front desks.Phil Libin, CEO of Evernote, which adapted its multimedia organizer, tagging and storage app for the iPad, says his Mountain View, Calif., company sees tablets’ appeal to a new type of user.”We don’t think of business users as any different from consumers,” Libin says. “It appeals to the modern knowledge worker.”last_img read more


Ford Wants This Creepy Robot to Bring Its Autonomous Deliveries to Your

Posted On Aug 30 2019 by

first_imgMay 22, 2019 This story originally appeared on Engadget 2 min read Growing a business sometimes requires thinking outside the box. Autonomous deliveries and self-driving vehicles may be the future, but there are still a few gaps that need to be addressed — namely that it’s not always possible for people to leave their homes to retrieve deliveries from the roadside (and if you’re hungover and ordering take out, you definitely don’t want to). Ford is working on a solution for this final stretch, though, and it’s come right out of a sci-fi movie.”Digit” is a two-legged robot created by Agility Robotics, designed to get your delivery from a car to your door. Announced earlier this year but now operational, the robot folds up in the back of a self-driving vehicle, ready to unfurl itself in a Lovercraftian manner when it arrives at the delivery destination. According to the press release, “Digit not only resembles the look of a person, but walks like one, too.” We’ll let you make up your own mind on that one.Digit can lift packages that weigh up to 40 pounds, walk up and down stairs and across uneven terrain, and can maintain its balance in the event of a bump. It makes the journey from the car to the door by tapping into data obtained by the self-driving vehicle. The car builds a detailed map of its surroundings, then wirelessly shares that with Digit. Through this data exchange, Digit and the vehicle can even work collaboratively to identify the most efficient delivery pathway.Digit looks creepy, there’s no two ways around that. But it might not be that long before you see the robot — or some kind of iteration of it — scuttling around your neighborhood. After all, a number of U.S. states have formally permitted the use of delivery robots on sidewalks, and numerous other companies are working on — and have launched — their own autonomous delivery solutions. None of them look quite like Digit, though. Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global Register Now »last_img read more

Demoted Catholic Cardinal believes homosexual culture to blame for child rape

Posted On Aug 29 2019 by

first_imgeTN Chatroom for Readers (join us) What he said‘I believe that there needs to be an open recognition that we have a very grave problem of a homosexual culture in the Church, especially among the clergy and the hierarchy, that needs to be addressed honestly and efficaciously,’ Burke said in an interview with Catholic Action for Faith and Family.‘It was clear after the studies following the 2002 sexual abuse crisis that most of the acts of abuse were in fact homosexual acts committed with adolescent young men. There was a studied attempt to either overlook or to deny this.’Burke went on to discuss how ‘anti-life’ and ‘contraceptive culture’ also contribute to this problem.‘I think it has been considerably aggravated by the anti-life culture in which we live, namely the contraceptive culture that separates the sexual act from the conjugal union,’ he said.‘The sexual act has no meaning whatsoever except between a man and a woman in marriage since the conjugal act is by its very nature for procreation.’ Catholic Cardinal Raymond Burke GAYSTARNEWS- Catholic Cardinal Raymond Burke responded to the recent revelation of over 300 ‘predator priests’ in Pennsylvania by blaming ‘homosexual culture.’center_img Burke’s homophobic historyThis is not the first time Cardinal Burke has expressed homophobic beliefs. In 2015 after Ireland legalized same-sex marriage, Burke said the country is ‘worse than Pagans’. Back in 2014, he stated that homosexual couples who want kids are ‘irresponsible’. Around the same time, he also said that gay couples shouldn’t be allowed at gatherings if children are present.‘If homosexual relationships are intrinsically disordered, which indeed they are… then what would it mean to grandchildren to have present at a family gathering a family member who is living [in] a disordered relationship with another person? If it were another kind of relationship – something that was profoundly disordered and harmful – we wouldn’t expose our children to that relationship, to the direct experience of it.’The demotionFollowing those 2014 remarks, Pope Francis demoted Cardinal Burke. Burke was once an Archbishop. At this time, he headed of the Roman Catholic Church’s version of the Supreme Court. He lost that position following the Pope’s demotion.‘The pope is not free to change the church’s teachings with regard to the immorality of homosexual acts,’ Burke said.Got a news tip?
