New Flexible Transparent Transistors made of Nanotubes

first_imgThe ability to create flexible, transparent electronics could lead to a host of novel applications, such as e-paper and electronic car windshields. Now, scientists have constructed a transistor made of a network of nanotubes that may serve as an essential component in a trans-flex device. Metallic-to-semiconducting nanotube conversion greatly improves transistor performance Such devices require two main components: light displays and current-controlling transistors. While scientists have found that OLEDs and LCDs work well as light displays, finding a truly transparent and flexible transistor material is still an open area. Usually, these transistors consist of metallic nanowires.Recently, researchers from Hanyang University in Seoul have constructed a thin film transistor made of networked single-walled carbon nanotubes (SWNTs) on a glass substrate. While it’s not the first thin film transistor made of SWNTs, it has the advantage of allowing a high density of SWNTs to be grown under lower temperatures than normally required.Most significantly, the method shows that nanotubes can offer a practical choice for fabricating transparent, thin film electronics such as flat-panel displays and future opto-electronics devices.“This works shows that we are able to build a transistor with thin films of SWNTs, rather than with single SWNTs,” coauthor Wanjun Park told PhysOrg.com. “It means that we have an easier fabrication method for building electronic devices made of nanotubes, without the need to individually control each single tube.”In a recent issue of Nanotechnology, the researchers explained how the SWNT network can be arranged through a technique called chemical vapor deposition. In this method, the substrate is pre-patterned with catalysts to avoid the need for etching, and the nanotubes can be directly deposited on the substrate. By enhancing this technique with the use of a water plasma, the scientists were able to grow the nanotubes at significantly lower temperatures than in previous methods.Due to the high SWNT density on the substrate, the nanotubes intersected with each other to form a continuous conductive path. However, for nanotubes above a critical percolation threshold (a measure of connectivity), there was no conductance. In this way, the SWNTs act like semiconductors, providing the basis for the on-off switching in the transistor.In the future, the scientists plan to make improvements to the nanotube transistors by increasing their mobility and further understanding the complex configuration of the nanotube networks.“These results are just the beginning,” Park said. “The technology needs lower temperatures for semiconducting SWNT growth, as well as higher transistor performance for real applications. But SWNT is a very robust material with outstanding electrical properties. It can be expected to be one of the candidates for a future electronic material.”More information: Bae, Eun Ju, Min, Yo-Sep, Kim, Un Jeong, and Park, Wanjun. “Thin film transistors of single-walled carbon nanotubes grown directly on glass substrates.” Nanotechnology 18 (2007) 495203 (4pp).Copyright 2007 PhysOrg.com.

Honeybees entomb to protect from pesticides

first_img(PhysOrg.com) — With the drastic rise in the disappearance of honeybee colonies throughout the world in recent years there has become a large focus on the study of honeybees and the effects of pesticides on their colonies. Termed ‘colony collapse disorder’ in 2006, the decline in honeybees throughout the world has been attributed to everything from pesticides to disease and parasites. The loss of the honeybee population is a concern for the agricultural community, given these bees are responsible for pollinating crops worldwide.

In examining honeybee hives, they have found cells containing pollen with high levels of pesticide have been sealed off by the bees using a waxy substance called propolis. While these bees are able to sense the contaminated pollen and try to seal it off from the rest of the hive, Pettis says this attempt is only proving futile and that the findings of sealed off cells in a hive are the biggest indicator of probable colony loss.Pettis believes the decline in the honeybees can be attributed to what he calls the “3-P principle” which represents poor nutrition, pesticides, and pathogens. While the pesticides are a contributing factor to the decline, he does not believe they are the only factor. With the increase in more intensive farming of one crop, a honeybee’s food source in an area can go from that of multiple sources to only one source, leading to poor nutrition. Beekeepers have also been using a substance to help control pests like the varroa mite that attacks honeybees. Unfortunately, the bees have also been found to entomb pollen cells they find containing this substance, showing that in may in fact also be harmful to the honeybee.

The foldable AMOLED display without a visible crease. Image credit: Kwon, et al. ©2011 American Institute of Physics. As the researchers explain in their study, which is published in a recent issue of Applied Physics Letters, recently there has been a great deal of interest in flexible, extendable displays. Most of these flexible displays are bendable or rollable. Fabricating a display that can fold completely in half would have the advantage of providing a large screen in a small, portable form, but so far it has been a challenge to eliminate the visible crease between panels.In the new study, the researchers have overcome this problem, demonstrating a seamless foldable active matrix organic-light-emitting-diode (AMOLED) display with no visible crease. The display consists of two AMOLED panels, silicone rubber (a hyperelastic material), a protective glass cover, and a module case. The display has a very small folding radius of just 1 mm, so that one panel lies almost completely on top of the other when the display is folded at a 180° angle. Also, the glass cover not only prevents scratches, but can serve as a touch screen, as well.The researchers tested the foldable display’s mechanical and optical robustness by performing 100,000 folding-unfolding cycles, and found that the relative brightness at the junction decreased by just 6%. Since this difference is hardly recognizable by the human eye, the deterioration is considered negligible. As the researchers explained, the key to making a display with no visible crease involved controlling the optical properties of the materials.“All the materials in a foldable window unit (glasses and silicone rubber) must have almost the same optical properties and attach to each other strongly without any optical property change,” coauthor HongShik Shim of the Samsung Advanced Institute of Technology told PhysOrg.com. More information: Hyuk-Jun Kwon, et al. “Mechanically and optically reliable folding structure with a hyperelastic material for seamless foldable displays.” Applied Physics Letters 98, 151904 (2011). DOI:10.1063/1.3576906 Citation: Foldable display shows no crease after 100,000 folding cycles (2011, May 12) retrieved 18 August 2019 from https://phys.org/news/2011-05-foldable-crease.html Explore further (PhysOrg.com) — One of the most difficult problems for designing mobile devices is finding a way to minimize the size of the device while simultaneously maximizing the size of the display. To get the best of both worlds, researchers from the Samsung Advanced Institute of Technology in South Korea have designed and built a prototype of a seamless foldable display that folds in half without a visible crease in the middle. Flexible and transparent OLEDs from TDK (w/ Video) As for applications, a foldable display could be useful in a wide variety of small, mobile devices, such as mobile games, cellular phones, tablet PCs, and notebook PCs. The hyperelastic silicone rubber is commercially available, which could make it suitable for mass production. In addition, the researchers plan to investigate applying this design to fabricate large-size flexible displays.“Our method has the advantage that mature, high-quality AMOLED display panels already exist,” said Shim. “But for real commercialization, some new processes and new materials must be developed, which takes about 1-2 years.” This document is subject to copyright.

Early universe may have been dominated by bobbing waves

first_imgOscillon simulations show that inflation may have been immediately followed by an oscillon-dominated phase of the early universe. Image credit: Amin, et al. ©2012 American Physical Society (Phys.org) — Localized waves that bob up and down without dissipating their energy, called “oscillons,” may have dominated the early universe shortly after inflation. A collaboration of physicists from MIT, Yale University, and Stanford University has discovered that copious amounts of oscillons arise in simulations based on several realistic inflationary models and could have caused novel gravitational effects in the early universe, although it is unclear whether the effects could be directly observed today. Play Oscillons are localized, time-periodic, extremely long-lived excitations of scalar fields with non-linear interactions. The animation above is a 2D slice through the center of an oscillon. Video credit: Amin, et al. Gravitational effectsThe physicists calculated that an oscillon-dominated universe would affect the density fluctuations that appeared around that time which later led to the formation of galaxies, stars, and planets. They found that the abundant oscillons would have enhanced the frequency spectrum of the early inhomogeneities, or primordial power spectrum, on very small scales. This enhancement, in turn, could have possibly led to novel gravitational effects at that time. “When gravity is included, oscillons attract each other, possibly forming bound structures and leading to structure formation not too different than what happens in the contemporary universe (except this happens on a very tiny length scale and very early on in the history of the universe),” Amin said. “In addition, oscillons can merge, fragment or scatter off each other in complex ways when they come close to each other. Another (even more speculative) possibility is that some of these objects could combine and collapse to form primordial black holes, which could then quickly evaporate. All of these possibilities need further work, and will keep us busy.”He added that the presence of oscillons would probably not have had any effect on present-day observations, since oscillons existed on scales much smaller than those that contribute to large-scale structure formation“It is unclear whether these primordial oscillons will have an effect today,” Amin said. “We have not fully understood their implications yet, especially when other particles and gravity is included in the simulations.”Amin and his coauthors are not the only scientists investigating the possible existence of oscillons shortly after inflation. Other researchers, including those at Dartmouth College and the University of Sussex, have also found that oscillons can be produced easily in different early universe processes. But they still have many unanswered questions to investigate.“Some of us are working on trying to understand how robust these oscillons are when new particles are included in the simulations, which can bleed energy from the oscillons,” Amin said. “Some questions we are interested in include: (1) Does the presence of oscillons delay the rate at which the inflation transfers its energy to other particles? (2) How do oscillons clump in the presence of gravity? Do they form clusters? Can they collapse to form primordial black holes? (3) We are also interested in studying what happens during collisions of oscillons. Such interactions will be important to understand the ultimate fate of a collection of oscillons produced in the early universe.” Copyright 2012 Phys.org All rights reserved.

According to the simulations, the oscillons in the early universe would have lived long enough for the universe to grow by a factor of 100 or more, under the assumption that the energy transfer to other particles is suppressed. This period could alter our view of what the universe looked like between the end of inflation and the beginning of radiation domination. “In many models of particle production after inflation, the inflaton rapidly transfers its energy to a turbulent sea of intermediary particles, which eventually decay into the particles we know and love,” Amin said. “Our work shows that, even if the energy transfer to other particles is suppressed, the inflaton can fragment rapidly into localized, coherent structures called oscillons. These oscillons are so ubiquitous that they can dominate the energy density of the universe at that time, which is definitely novel! In terms of altering our basic picture of the early universe, the presence of oscillons increases the clumpiness of the universe on small scales at the end of inflation. Their presence might also alter how the energy from the inflaton is eventually transferred to other particles, and how long it takes to do so. However, to make concrete statements about this and its impact on astrophysics in general, we need to study more realistic models including many more types of particles and gravitational interactions between oscillons.”Amin explained that, although these oscillons would have been much too small to see and very short-lived, the sheer number of them would have enabled them to have a significant impact on the early universe.“In the class of models we have considered, the oscillons are smaller than the Hubble horizon at the time of production,” he said. “The Hubble horizon is a measure of the typical distance light can travel while the universe doubles in size, and can be smaller than the size of an atom. Although small compared to human scales, oscillons are large in the following sense. Oscillons can be thought of as a bag of a large number of inflaton particles. This bag of individual particles can be extremely heavy compared to the heaviest known particles. Although exact numbers of oscillons produced depend on the details of the models used, enough of them can be produced to dominate the energy density of the universe at that time. Their lifetime is a tiny fraction of a second. However, even in this tiny fraction of a second, the universe doubles in size many times over! So as far as this doubling timescale of the universe is concerned, they live extremely long and can have a strong impact on the dynamics within the universe at that time. Regarding whether they move in unison, our simulations show that most of the oscillons do not move much once they are formed (as we mentioned before, they are rather heavy), and the distance between them increases as the universe expands. However, if the gravitational force between them is included, they might clump together to form clusters of oscillons.” Citation: Early universe may have been dominated by bobbing waves (2012, July 24) retrieved 18 August 2019 from https://phys.org/news/2012-07-early-universe-dominated-bobbing.html The physicists have published their paper on the possibility of oscillons existing after inflation in a recent issue of Physical Review Letters.As the scientists explain in their paper, oscillons are massive, long-lived excitations of a scalar field that are localized, i.e., they do not dissipate like ripples produced by dropping a pebble in a calm pond. Instead, an oscillon switches between being a hill and a crater, alternately rising above and sinking below the spatially uniform state of the field. In previous experiments, scientists have created oscillons by vertically vibrating a plate with a sufficiently thick layer of granular particles. As long as they’re not disturbed, oscillons will continue to move up and down for hundreds of thousands of oscillations.Oscillon-dominated universeIn the new study, the physicists used simulations to investigate the requirements needed for oscillons to form just after inflation, the period of rapid expansion that occurred from 10-36 to 10-33 seconds after the Big Bang. In a class of inflationary models that include some string models and supergravity-inspired models, the scientists found that inflation is followed by self-resonance that in turn generates large numbers of oscillons. “At the end of inflation, the inflaton (the agent responsible for inflation) is oscillating up and down, in sync throughout the universe,” coauthor Mustafa Amin at MIT told Phys.org, speaking on behalf of his coauthors Richard Easther, Raphael Flauger, and Hal Finkel at Yale University (now at the University of Auckland in New Zealand, the Princeton Institute for Advanced Studies, and Argonne National Laboratory, respectively), and Mark Hertzberg at Stanford University.“However, this synchronous, homogeneous state cannot be maintained for long,” he explained. “It is unstable and quickly fragments into an inhomogeneous, clumpy state. The rapid transfer of energy from the synchronous to the clumpy state is what we call self-resonance. We refer to it as self-resonance because the energy is shuttled from the synchronous, homogeneous state to the clumpy state of the inflation field itself. Interestingly, the mathematics describing this transfer of energy is identical to that describing a child pumping a swing. The child’s pumping plays the role of the homogenous, oscillating inflaton whereas the arc of the swing is related to the energy in the clumpy state.” Journal information: Physical Review Letters Explore further PausePlay% buffered00:0000:00UnmuteMuteDisable captionsEnable captionsSettingsCaptionsDisabledQuality0SpeedNormalCaptionsGo back to previous menuQualityGo back to previous menuSpeedGo back to previous menu0.5×0.75×Normal1.25×1.5×1.75×2×Exit fullscreenEnter fullscreen More information: Mustafa A.

Getting back whats ours

first_imgThe National Museum in the Capital is holding a month long show of the single piece of work to emphasize on the fact that what belongs to the country must be strictly protected.A seminar was held recently based on the same thought process where the unanimous consensus was that a detailed, nationwide documentation of all existing monuments across cultures and regions is essential so as to avert illicit international trafficking of antiques.Simultaneously, the country requires an environment that encourages the development of a domestic market for artefacts by suitably amending the Antiquities Act, according to experts at the symposium on Return of Yogini: Art & Crime noted during day-long deliberations. The speakers also discussed ways of creating general awareness about heritage objects, thus promoting transparency through better informed public stakeholders. Also Read – ‘Playing Jojo was emotionally exhausting’The meet was organised by the National Museum Institute (NMI) as part of an ongoing exhibition — The return of the Yogini — that displays an exquisite 10th-century stone sculpture which recently returned to the country from Paris to where it was smuggled out a quarter century ago.The single-object exhibition organised by the National Museum was to end on 6 October, but has been extended till 20 October, owing to public request, according to Dr Venu V, director-general of the museum.last_img read more

Delhi schools stir

first_imgAfter Prime Minister Narendra Modi launched the Swachh Bharat mission by sporting a broom, sweeping no longer held the taboo it once did. Business magnets, celebrities and political honchos have been seen sweeping floors, by-lanes, etc. It is a welcome change, considering that sweeping was once seen as the duty of the safai karamcharis only. Despite all the glamour surrounding Modi’s pet project, things have not changed much in government schools. Under the mission, the Centre had also planned on building toilets in schools for boys and girls separately, to further push the cleanliness drive. Millennium Post conducted a check at government schools in Delhi to find out whether the cleanliness drive has made any impact or not. Also Read – A vintage affair with Shyam SundarThe impact of the Swachh Bharat campaign was visible at a government school at Khichripur in East Delhi. The school looked clean and well maintained. The area where students would collect drinking water, was earlier waterlogged. However, school authorities have now managed to maintain it  better. Replying to a question  about how the cleanliness campaign has changed their condition, school headmaster Tekchand said, ‘It has made a difference. Things have changed and more importantly we have started to feel that it is for our own wellbeing. If the prime minister can take such an initiative, then why can’t we?’ Tekchand asked. Also Read – Melodious Mavericks – Jatin LalitTeaching, as well as non-teaching staff from the school, also echoed the same sentiment. However, at the same time they complained about shortage of toilets at government schools in the national capital. ‘The cleanliness initiative is all well and good. But there is an urgent need to improve toilets to student ratio in schools. For 710 students in our school, we have only two toilets-one for boys and one for girls,’ said a staff member, who does not want to be named. Similar figures came to light after Millennium Post took stock of a government school in South Extension area. The co-ed school, with a total strength of 454 students, has only one toilet for boys and one for girls. Contrary to the shortage of toilets in the school, its principal was happy to show the neat and clean premises of school and toilet. It is important to note here that she was promoted to the post recently. ‘I cleaned my office after taking charge. We have got orders to maintain hygiene in the school, and students have also contributed to maintain general cleanliness. Senior government officials have inspected our school a couple of times,’ the principal said.When Millennium Post examined the effect of the Swachh Bharat Abhiyan campaign at a government school at Vinod Nagar, the situation looked rather desperate. Most of the toilets were blocked, while classrooms were found in a mess. The school administration cited the end of the session as its reason for the poor state of hygiene. Their science lab was found in a decrepit state, with random posters of political candidates found stickled inside the lab. To address the cleanliness issue at schools, the central government has laid out a school maintenance schedule. According to the schedule, some members of the school management committee (SMC) as well as teachers will have to take responsibility for maintaining the school. Members of the SMC, as well as school teachers will have to take responsibility for maintaining the school Operation and Maintenance (O&M) schedule. The schedule refers to periodic visits by the district/ BRC/CRC staff to check if the maintenance schedule is being followed in earnest. The government has also fixed a ratio of one unit of toilet for 40 students. A unit comprises of one toilet and three urinals. A recently conducted survey titled, ‘The Delhi Story 2014’, has also highlighted the shortage of functional toilets in schools. The survey, which covered 1,823 households and 49 schools, and spread across nine districts of Delhi, was carried out by student volunteers from Delhi University in association with The Energy and Resources Institute (TERI) and the Indian Institute of Technology (IIT). According to the report, 43.5 per cent of students said that they did not have functional toilets in their schools and 47.61 per cent said the drinking water facilities were not adequate.The RTE Act 2009 provides a legally enforceable framework with certain time targets that governments must adhere to. The RTE Act lays down the norms and standards, including drinking water and sanitation for a school building. A school building has to be an all-weather building comprising of at least one classroom for every teacher, barrier free access, separate toilets for boys and girls, and an adequate drinking water facility for all children. But the situation is very different on the ground. It is a fact that things will not change at one go. It needs a long term plan, which needs to be followed efficiently. Despite the shortfalls, due to limited resources, at least the desire to present an image of cleanliness has come to the fore. However, there is a long way to go before we witness tangible results on the ground.last_img read more

Call for foolproof system grows louder as fuel pilferage from tankers rise

first_imgKolkata: Retail petroleum dealers have complained of receiving lower quantity of fuel from oil tankers which they say has risen sharply in step with surging fuel prices. Oil Marketing Companies (OMC), however, rubbished the claim saying there is no room for dispute as proper checks are already in place.”The short supply of fuel was always there but the difference has now jumped sharply. The minimum shortage we are experiencing now is 50 litres which can go up to 100-120 litres,” West Bengal Petroleum Dealers Association president Tushar Sen told PTI.

An Oil Tankers Association office-bearer declined to comment on the issue.Meanwhile, the BPCL official said a new automation system of geo-fencing is being tried out.The technology is supposed to track and prevent opening of the lock of an oil carrier until the vehicle reaches the exact coordinate of the dealer’s location.”It will match the latitude and longitude of a location before it allows to open the lock,” the official said.last_img read more

Gajoldoba on poll day Serving peace over khichdi curry

first_imgKolkata: Gajoldoba in Malbazar sub-division of Jalpaiguri stood out to be a different electoral battle where the supporters of the ruling party and that of the Opposition sat together and had their food upholding a spirit of a celebration. Not a single incident of violence was reported in the area. The voters were in a picnic mood from Monday morning. The local Trinamool Congress leaders had come up with a unique idea of serving khichdi and curry not only to the voters turning up at the booths but many others were seen to be taking part in the programme. Non-voters also sat with the voters and enjoyed their food. Also Read – Heavy rain hits traffic, flightsIt was a different scenario altogether in Malbazar where the activists from the political parties like Trinamool Congress, BJP and CPI(M) joined together and had their food sitting next to each other. The political rivalry took a backseat when Trinamool Congress local workers served food to all the voters without considering their political affiliations.The electoral exercise turned violent in some parts of the state on Monday and some stray incidents were reported in some districts but Malbazar sub-division set an example as to how the democratic franchise can send across a message of peace and harmony. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedThe local Trinamool Congress leaders decided to arrange food for all who would participate in the election process. Hence a few cooks were brought in. All necessary arrangements were made so that a large number of people could be served food. Khichdi and curry were not only served to the voters, it was also arranged for a considerable number of election employees who went there to conduct the polls. A local Trinamool Congress leader who was a part of the programme said they do organise such events during the polls days. The political rivalry hardly has any impact on the people in the area. Completely forgetting their political lineage, people in large numbers participated in the event, enjoyed the food sitting with one another. People passing through the area who were not part of the election process also sat together with the voters and the election employees and had their food. The hospitality extended by the organisers did not however dip when it came to the non-voters.The initiative proved all the more successful with the locals coming forward in large numbers. It only shows how peaceful the election process was in this small part of Jalpaiguri district that set an example for one and all. The locals also added that irrespective of their political affiliations, people joined them on the table to have food and this was what made it a unique election here.last_img read more

Policepublic cooperation necessary to make Safe Drive Save Life a success CM

first_imgKolkata: Chief Minister Mamata Banerjee on Friday sought police–public cooperation for success of the Safe Drive Save Life scheme.”Like Kanyashree that has bagged international awards, Safe Drive Save Life programme will also earn world recognition someday,” she said while inaugurating Jay Ho, a cultural evening organised by the Kolkata Police at Netaji Indoor Stadium on Friday.She said since the implementation of Safe Drive Save Life programme, the number of road accidents has come down drastically. “It will be a great achievement if we can bring down the number of road accidents even by 1,000. Parents go through unbearable pain when they lose their sons or daughters in road accidents,” she said and added: “We must keep in mind how much efforts parents have to make to raise their children and if road accidents claim their lives, then for them everything comes to a standstill in seconds.” Also Read – Rain batters Kolkata, cripples normal lifeRecalling her interaction with a few journalists who had recently visited Sikkim, she said: “The journalists have told me that they saw the Safe Drive Save Life slogan in Sikkim also.
