(PhysOrg.com) — Japanese researchers, led by Masashi Kawasaki, have discovered that a previously known kind of double layered material created using electrostatic doping can be used as a superconductor. The team, working out of Tohoku University, found that by creating a double layered material using an ionic liquid atop a platform of potassium tantalum oxide (KTaO3) with deposited electrodes, a superconductive state could be made to exist by cooling the result to near absolute zero. They have published their results in Nature Nanotechnology.The authors are quick to point out that they have not created a new superconductive material, but have instead figured out a way to make a known material become superconductive by means of electrostatic doping (using electrostatic properties to control the conductivity of a material). They contrast this with more traditional methods that use chemical doping (adding chemical impurities to a substance to allow for controlling the amount of current that passes through it) which they say means a material might be found that would allow for superconductivity at room temperatures; the holy grail, or course, for many researchers for many years.The first part of the process, which had already been established, works by adding a drop of ionic liquid onto a set of electrodes that have been placed on a base of KTaO3. Doing so causes a double layer to form between the materials with a gap between them of approximately 2nm. When electricity is sent to the electrodes, the charge adheres electrostatically to either side of the gap, creating a sort of capacitor. The next part is new; this is where the team subjected the result to lowered temperatures, measuring the conductivity across the gap as they went. They found that as things got colder the conductivity changed; first, from that of an insulator, then to that of a metal, then to a semiconductor and finally, to that of a superconductor, at around 0.005K, very close to absolute zero.If the research team is successful in a finding another material that would provide the same results at room temperature they would set the stage for a whole new generation of electronic circuits that would be able to operate with very little power and produce little to no heat; options that would likely open the door to new and exciting types of computers and other types of electronic devices. More information: Discovery of superconductivity in KTaO3 by electrostatic carrier doping, Nature Nanotechnology (2011) doi:10.1038/nnano.2011.78Superconductivity at interfaces has been investigated since the first demonstration of electric-field-tunable superconductivity in ultrathin films in 19601. So far, research on interface superconductivity has focused on materials that are known to be superconductors in bulk. Here, we show that electrostatic carrier doping can induce superconductivity in KTaO3, a material in which superconductivity has not been observed before. Taking advantage of the large capacitance of the self-organized electric double layer that forms at the interface between an ionic liquid and KTaO3, we achieve a charge carrier density that is an order of magnitude larger than the density that can be achieved with conventional chemical doping. Superconductivity emerges in KTaO3 at 50 mK for two-dimensional carrier densities in the range 2.3 × 1014 to 3.7 × 1014 cm−2. The present result clearly shows that electrostatic carrier doping can lead to new states of matter at nanoscale interfaces.

AMDs Trinity is out to rattle Intels Ivy Bridge

first_imgA BBC report on the Trinity launch carries comments from AMD’s CTO, Joe Macri, who talked about Trinity’s Piledriver architecture of the CPU cores. He referred to Piledriver’s energy-saving technique, which is “resonant clock mesh technology,” where some of the energy consumed while doing calculations is recycled. Further, power savings have been achieved, says AMD, by running more processes on the GPU. The power is dynamically shifted between the CPU and GPU depending on application needs.Trinity is using AMD Radeon HD 7000 Series graphics for an increase of graphics performance up to 56 percent over the previous generation, claims AMD. Trinity offers HD, 1080p resolution gaming, delivering 30 frames per second. Similarly, the industry standard for smooth gaming is 30 frames per second. While graphics performance features are a marketable strength for gamers, AMD could also benefit from a class of business computer users whose work could use higher-end graphics capabilities, as for high-definition video discussions and trader applications, where multi-screen support and high-speed rendering are important.AnandTech, in assessing Trinity’s performance, found that, while AMD had a tough job of increasing performance without ballooning die size, the die size went up only by around 7percent and yet AMD achieved “double-digit increases” over Llano in CPU and GPU performance. “If you liked Llano, you’ll love Trinity,” said the report. According to AMD, Trinity has up to 12 hours of battery life, whereas Llano offered 10.5. Once products appear that carry Trinity processors, the real numbers will either comply or will need some adjustments. Besides HP, according to reports, Asus, Lenovo, Samsung, Toshiba, and Acer may announce mobile devices based around Trinity shortly. The battery-life calculations that were announced by AMD are based on the average power on multiple benchmarks and usage scenarios, said the company. Twelve hours of battery life are based on Windows Idle (740 min./12:20 hours) as a resting metric.Technology strengths in Trinity center on having fine-tuned power management.

Industrial design students create solar bag that purifies water while person walks

first_imgThe two say that their Solar Bag can purify two and a half gallons of water in six hours, the same amount of time it typically takes other systems to treat much less water. Unfortunately, the bags aren’t yet being commercially produced; the two are currently looking for a backer. They say that the material costs for one Solar Bag amount to just $5, and possibly less if manufactured in bulk. (Phys.org) — It’s common knowledge that a lot of people in the world don’t have access to clean drinking water. In some parts of Africa, people, particularly children fall victim to bacteria in the water they drink; a lot of them die. For some, getting to a water source, even one that isn’t clean can mean walking for several miles, and then carrying it back. It’s for these people that industrial design students Ryan Lynch and Marcus Triest have designed and created what they call the Solar Bag, it’s a bag that holds water and hangs off the shoulders and lies on a person’s back and uses UV radiation from the sun to kill bacteria in the water while the person is walking or after they have arrived at their destination. To create their bag, they turned to a method of water purification known as SODIS, where PET (made of polyethylene terephthalate – the type of plastic used for soft drinks) bottles filled with water are exposed to sunlight for up to six hours, allowing UV radiation to kill most of the bacteria in it. Instead of bottles they created a two sided bag. On the outer side, the one that faces the sun when a person walks, is clear plastic that allows the UV rays to enter. On the inner side is black plastic that absorbs heat, helping the UV rays do their job. The bag is then connected to straps that allow the water to be carried like books in a common backpack. The bag can be hung on a wall as well, for continued treatment after the person carrying it arrives at their destination. It also has a tap at the bottom to let the water out and a squeeze balloon with filter for additional purification. © 2012 Phys.org Explore further This document is subject to copyright.

Model shows ejection of gasses around black holes due to magnetism

first_img Explore further An international team of researchers has created a model to explain the force that causes gases to be blown away from a black hole and have found the force to be magnetism. In their paper published in the journal Nature Astronomy, the team describes the factors that went into their model and the degree of confidence they have in it. A black hole devouring a star. Credit: NASA Journal information: Nature Astronomy Hubble gazes into a black hole of puzzling lightness Citation: Model shows ejection of gasses around black holes due to magnetism (2017, March 7) retrieved 18 August 2019 from https://phys.org/news/2017-03-ejection-gasses-black-holes-due.htmlcenter_img © 2017 Phys.org Scientists have suspected that magnetic fields were responsible for pushing gases away from a black hole since the 1970s, but there was not a consensus—others suggested it might have been due to the heat of the gas. In this new effort, the researchers built on a prior model that had found magnetism to be the force pushing gas away from a giant black hole—this time, they based their model on small black holes and found the same result. This, the team suggests, means that it is likely the case for all black holes.The gases in question come from a companion star—the black hole strips the star’s gas and as it does so, creates a spiral with an accretion disk. As the spiral turns, an electric current is generated in the accretion disk, which forms a vortex pulling in more and more matter. But, the model showed, some of the magnetism serves to push gas from the outer edges of the spiral out into space, where it escapes and can be observed by X-ray telescopes on Earth.The model also ruled out heat from the gas as the cause for its expulsion—if it were heat, the model showed, the gas would have been blown much farther than readings have shown. The researchers suggest the magnetic fields likely arc from pole to pole, though there is still no way to prove it. They note also that the expulsion of gas from around the black hole could be powerful enough in some situations to actually push out all of the gas, leaving the galaxy it inhabits empty and unable to form new stars. Such galaxies have been observed as simple blank red areas in space. More information: Keigo Fukumura et al. Magnetic origin of black hole winds across the mass scale, Nature Astronomy (2017).

Panchayat violence intellectuals criticise TMC admn police

first_imgKolkata: A section of intellectuals today castigated the ruling Trinamool Congress, the administration and the police, claiming that they have remained “silent spectators” while widespread violence is taking place in West Bengal during filing of nominations for next month’s panchayat elections in the state. Former state advocate general Bimal Chatterjee said unleashing of violence to ensure a walkover in the panchayat elections is nothing but incapacitation of democracy.

Siliguri train mows down 2 jumbos forest dept to lodge FIR against

first_imgDarjeeling: The Forest department will be lodging an FIR against the motorman of the Intercity Express train that mowed two elephants (mother and cub) in the Jalpaiguri district on Friday morning.The incident occurred at around 7:45 am in between Redbank Tea Estate and Debpara Tea Estate near Railway Pillar 875 and Banarhaat when a herd of elephants were crossing the tracks. The train runs between Siliguri Junction and Alipurduar.While the mother and the calf died on the spot, the rest of the herd moved into Dyna forest. “We have been constantly coordinating with the railways regarding elephant movement throughout the State. In the past, we have requested the railways to ensure that motormans exercise caution while driving through elephant corridors. It seems they have turned a deaf ear,” retorted Binay Krishna Burman, Forest Minister, Government of West Bengal.This year, four elephants have been mowed down by speeding trains (including these two elephants) in North Bengal.Since the conversion of the Jalpaiguri-Alipurduar railways track to broad gauge from meter gauge in 2004, 70 elephants have been killed.Ujjal Ghosh, Chief Conservator of Forest (Wildlife), Northern Circle: “The area in which the elephants were mowed down is an established elephant corridor.On Thursday, we had informed the Railways of elephant movement in the area and even intimated them of the location. The elephants were mowed down 500 meters away from the area we had earmarked. Ironically, the accident happened in broad daylight. We will lodge an FIR against the engine motorman.”The railways have constituted an enquiry committee. “The committee after conducting a thorough enquiry will submit its report,” stated Chandravir Raman, Divisional Railway Manager (DRM), Alipurduar.He, however, stated that the motorman of the train had applied emergency brakes when the elephants appeared on the tracks suddenly.”There is speed restriction of 30 km per hour from 5 pm to 5 am. As the accident occurred after 5 am, there was no speed restriction in the region at the time of the accident,” added Raman.Forest employees complain that the train was at a high speed at the time of the incident.last_img read more

Asian Cup Aim is to advance from group stage says Constantine

first_imgKolkata: Indian football coach Stephen Constantine believes the team can make it out of the group stages of the forthcoming Asian Cup, a tournament in which the country has time and again failed to shine. “I honestly believe we can get out of the group and that is our target. Of course, we need to be on our game in all three games and we will take one game at a time,” Constantine told IANS from Abu Dhabi. In their previous three attempts, India’s best performance in the continental competition came 55 years ago when they finished runners-up. Also Read – Rain batters Kolkata, cripples normal life India had gained a direct qualification to the finals of the tournament in 1964 after several Western Zone teams pulled out due to political reasons. Under English coach Harry Wright, India had got the better of South Korea and Hong Kong to cement their second place in the four-nation round-robin format meet. The team had to wait 20 years to qualify for the finals again, and in both occasions (1984, 2011) bowed out of the group stages. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedUnder Constantine, the Sunil Chhetri-led side has done well in recent times, attaining close to an all-time-high FIFA ranking and qualifying for the finals of the Asian Cup as group-toppers ahead of Kyrgyzstan, Myanmar and Macau. The English-Cypriot coach, who is in his second stint with the national team, said the fact that they have the second youngest team in the competition augurs well for Indian football going ahead. “We are, in fact, the second youngest team in the Asian Cup and that is a huge plus for Indian football going forward as these boys now go into the future with the experience of a major event. “The experience of the older lads is also important and I am sure the youngsters will do India proud,” the 56-year old stated. In the lead up to the big-ticket meet, India have played China, Jordan and Oman in preparatory friendlies. Constantine had previously said the boys could do with a few more games with top Asian teams. “Yes, we could have done with a couple of more games but it wasn’t for the lack of trying…. it just didn’t happen. But we have had several very difficult games and overall I am happy with the way things are going,” the coach said when asked whether he is content with how things have shaped up. India are already in Abu Dhabi where they will take on Thailand on January 6 at the Al Nahyan Stadium. Constantine said it will act an as advantage. “It’s a big plus for us having been here a good two weeks before the first game against Thailand on January 6.” India played out a goalless draw against current Gulf Cup of Nations champions Oman after reaching here. Constantine said the result was encouraging ahead of the games but at the same time showed what they need to work on. “Well, after last night’s result against Oman there are always going to be a few things that we can work and we will look to do that before the Thailand game,”he concluded.last_img read more

The 1796 Perfect Wife Experiment Took Control Freak to New Levels

first_imgDuring his studies at Oxford, the author Thomas Day was amused by Jean-Jacques Rousseau’s book Emile, or On Education, which contained practical ideas about education. Inspired by the book, Day decided to write a list of requirements for his future wife and started searching for one. While in university he was rejected by a few women, hence, he decided to make one, i.e. to educate one, using his own concepts and Rousseau’s theory. In 1796, supported by his barrister friend by John Bicknell, Day chose two girls from orphanages, ages 11 and 12. His idea was that the one who would prove herself to satisfy his concept of a perfect woman would become his wife.Day, who inherited a fortune from his father in his infancy, has been described as a short-tempered character with a brooding personality and a face marked with smallpox scars. His friend Richard Lovell Edgeworth was also introduced to Rousseau’s work and the two men became admirers of the philosopher, with a particular affinity for his book Emile, or On Education.Thomas Day in 1770Day had performed his first Emile style educating exercise, the learning-by-doing technique, on Edgeworth’s son, Dick. After graduating from Oxford, he accompanied his friend to Ireland as a tutor to Dick. After falling in and out of love, Day concluded that it would be impossible to find a wife who would match his standards.Blaming women’s education for his “misfortune,” he found the solution in “creating” his ideal wife, which meant that he should raise her from her adolescence using the techniques laid in Rousseau’s book.Richard Lovell EdgeworthAlong with his friend, Bicknell, an English barrister and writer, Day created a plan to find two girls who he would groom to become a perfect wife. Just as the expectations of any experiment, a failure was anticipated, so he decided on taking two girls instead of one – if one failed to “pass the test,” the other probably wouldn’t. So, right after his 21st birthday, a time when he was also given a full access to his money, Day traveled with Bicknell to the Shrewsbury Orphan Hospital to select the first girl. Day had a hard time choosing a girl, so Bicknell picked out a 12-year-old named Sabrina.Sabrina was described as beautiful and with a pleasant voice. Of course, the reason for adopting a girl wasn’t mentioned to the orphanage secretary, instead, by the orphanage policies, for the foster parent to be in marriage, the two friends stated Edgeworth as the person legally accountable for Sabrina. At the time Edgeworth wasn’t aware of the arrangement. Sabrina and Day met for the first time at the lodgings in London, in August 1769. He changed her name to Sidney after one of his heroes, Algernon Sidney. Just a month later he chose the other girl for his experiment and named her Lucretia, after the Roman matron.Shrewsbury Orphan Hospital, which now forms part of Shrewsbury School. Photo creditA contract was made for the girls stating that in a period of a year, Day would choose the one he would marry while the other one would be given as an apprentice to a woman in a trade and also a fee of 100 pounds (equivalent to $15,734 in 2017). When the girl decided to marry, or if she were willing to start her own business, Day would pay her a further 400 pounds (equivalent of $62,936 in 2017). In case he decided not to marry his intended bride, he would pay her the fee of 500 pounds (equivalent of $78,671 in 2017). Bicknell signed as guarantor for the contract.Wishing for the girls to be influenced solely by him, Day moved with them to France. As they could not understand French, it was easy for Day to be their sole educator. Following the education techniques in Emile, Day focussed exclusively on the girls’ education. He expanded their primary education to basic arithmetic and reading while at the same time they had responsibilities such as cleaning, cooking, and other housework. Willing to discuss complex concepts with the girls, Day taught them rudimentary theories in physics and geography. The girls received tasks such as observing the seasons’ changes and writing down details of the sunsets and sunrises. Day also presented to them the philosophical contempt for luxury according to Rousseau.Rousseau’s Emile, or On EducationIn his letters to Edgeworth, Day revealed his favoring of Sabrina as she appeared more willing to be taught than Lucretia. However, according to 19th-century historians, both girls became bored with their education, which made Day impatient and angry. In the spring of 1770, Day and the girls returned to England. where Lucretia was apprenticed to a milliner while Sabrina’s education was taken to another level.In Emile, Rousseau explains the concept of “negative education,” which Day interpreted to mean that he should submit the girl to endurance tests that would help in hardening her nerves. Attempting to increase Sabrina’s resistance to pain, for example, Day would pour hot sealing wax over her back and arms, or stick pins in her while at the same time he commanded her not to cry out. Rousseau also stated that the person would get accustomed to explosives if, for example, fireworks or pistols explode near them. So Day shot a pistol loaded with powder directly into the girl’s petticoat.To test her resistance to luxury, Day gave Sabrina a box full of silk and ordered her to throw it all in the fire. In the end, he had some success with her education but not a complete one. Sabrina could endure the hot wax without a sound but couldn’t prevent herself from screaming when Day fired his gun at her. There came a time when Sabrina started questioning the techniques that Day used and to complain about things she was asked to do. Edgeworth visited Day and Sabrina for Christmas 1770 and suggested to his friend that the experiment had failed and that he couldn’t keep Sabrina any longer without marrying her because she was already too old.Frontispiece to Rousseau’s Émile by De Launay for the 1782 edition. The original caption reads: “A man’s education begins at birth”Day made a decision and in early 1771 sent Sabrina to Sutton Coldfield boarding school, where she remained for three years. In 1774, he arranged for Sabrina to become an apprentice to the Parkinsons, a dressmaking family. She fitted greatly in her new position, and the family treated her well, but unfortunately, their business went bankrupt less than a year later, leaving Sabrina with nowhere to go. Day arranged for her to become a housekeeper at the home of his friends, the Keir family.When Sabrina was 18, Day started reconsidering his decision to marry her. He began testing her again, and she appeared more responsive to his requirements, which made him think that he might have successfully created a perfect wife for himself. She found out about his intentions and eventually agreed to marry Day, so they became engaged.However, he was strict in his requirements about how she dressed and during one visit to the Keir family, Day gave precise instructions to his “future perfect wife” about what to wear. Moreover, it just happened that on the next visit to his friends, Sabrina wasn’t dressed by Day’s instructions, which resulted in his furious anger. He made his final decision:  Sabrina did not fit his image of a perfect wife so he called off the engagement, sent her to a Birmingham boarding house with a stipend of 50 pounds per year (equivalent to $7,134 in 2017), and resolved never to see her again.Day was finally married in 1778 to an heiress, Esther Milnes. After eight years living in boarding houses around Birmingham, Sabrina received a marriage proposal from an apothecary. She wrote to Day asking for permission, but his answer was a strict no, and he even wrote a letter of refusal for her.Bicknell steps back into the story in 1783. He proposed marriage to Sabrina and again, she consulted Day about this. When once again he advised her not to accept the proposal, Bucknell told her the whole truth about her adoption and the purpose of her education.Sabrina, aged 75The failed perfect wife was furious when she realized the true nature of her education. She wrote several letters to Day in which she expressed her anger. Although he confessed that it was true, Day never apologized to Sabrina. Things settled and she eventually married Bicknell, while Day paid her dowry of 500 pounds in accordance with the contract made when he adopted her. The couple bought a house and had two children. However, the money they had disappeared due to Bicknell’s gambling habits. After only three years of marriage, Bicknell died of a paralytic stroke, leaving his family without any savings nor income.Related story from us: Nine drops since 1930: The longest running pitch drop lab experiment in historyHowever, Day sent Sabrina a new stipend of 30 pounds per year. Bicknell’s barrister friends raised some 800 pounds for her and the children, and she also found a job as housekeeper in the home of Charles Burney, a schoolmaster, and clergyman. After Day’s death, his widow, Ester, continued to send money to Sabrina who worked for Burney until she was 68.By the time she stopped working, Sabrina had her own four-storey house with servants. She died of a severe asthma attack in 1843, at the age of 86.last_img read more

How Augmented Reality Startups Can Change Our Work Reality

first_img This hands-on workshop will give you the tools to authentically connect with an increasingly skeptical online audience. Enroll Now for Free Google Glass may not be dead, but it hasn’t exactly taken off as a consumer product. In January, the company killed its social media presence, ramping up its focus on its Project Aura headset instead. This decision points to the future of augmented reality technology as an enterprise solution, and other companies have already entered the market.Some companies are leveraging existing hardware such as iPads and smartphones, but others are developing innovative new products in the AR space. Magic Leap has raised almost $800 million for its “cinematic reality” device (which could be an AR contact lens, if the company’s patent applications are any indicator).And at least one reviewer has deemed Microsoft’s HoloLens “the future of computing.”Related: This Is What It’s Like to Strap a Microsoft HoloLens on Your FaceDigitally improving the real worldAlthough consumers may view AR technology as a gimmick, it could actually revolutionize the workplace by streamlining bulky processes and improving safety and communication.For example, AR technology is helping to transform employee onboarding. Instead of dispatching an employee to spend his or her entire workday training a new hire, AR allows each worker to access context-specific information at any moment. GetVu is one company leading this charge, using wearables and AR to increase efficiency and decrease packing errors in warehouses.Some of the earliest users of AR technology came from the design and construction industries. DAQRI’s smart helmet captures information about a user’s surroundings and delivers instructions and safety guidelines. In highly specialized settings, Scope AR’s Remote AR can deliver 3D instructions to technicians in the field.The possibilities aren’t limited to technical support and training, either; big data visualization has huge potential. Creating a virtual environment for data presentation may take a lot of creativity and computing power, but some early adopters have created handy tools for 3D visualization: An example is IBM and its Max Reality.Enterprise startups can light the way.AR technology is poised for a bright future, with engaged employees, knowledge-sharing and improved, automated data collection. Enterprise startups should follow these four steps to position themselves for leading the charge in this market:Survey the stakeholders. Whether you work with universities or hospitals, architects or warehouse workers, you should find out where the technology will have the most impact. The best augmented reality must reflect actual reality: If a job site is too dark or employees must always wear thick gloves — as Bentley Systems has suggested for utilizing AR in construction — AR may be effective solution. No application is too small.Related: Why Your Startup Needs Augmented Reality Business CardsThink about hardware. Don’t take legacy systems for granted. Many of the enterprise applications of AR are in physical or dangerous environments, and Google Glass or Microsoft’s HoloLens might lack the necessary durability. DigiLens, on the other hand, is in the process of designing an AR helmet for motorcyclists, a scenario in which durability is paramount. An AR application will lose relevance quickly if the hardware cannot stand up to its intended operating environment.Target motivated trailblazers. Find the industries facing big challenges at the intersection of the physical and digital. This could be manufacturers looking to drive efficiency and save money, or farmers needing data to optimize harvests. The companies with the biggest needs will be the ones most motivated to invest and push the limits of this new technology.Consider data inputs. As evidenced by a recent presentation on using HoloLens apps for tracking airline flights, AR technology needs data to function effectively. Find the most valuable and contextual data to drive the desired output. Will static information be enough to optimize the solution, or will it require real-time sensors? A great interface is useless if it lacks the necessary data.Related: 5 Magical Augmented Reality Apps You Should TryCompanies looking to invest in AR technology must ensure that their approach is driven by ROI, but there are many reasons for optimism. Innovators are creating bold new products and leveraging the existing architectures of mobile devices to drive real progress across a range of applications. And that’s creating multiple avenues for growth in the workplace. AR is no longer the future; it’s already here. 4 min read Opinions expressed by Entrepreneur contributors are their own.
