Image by Hong Lee, © American Institute of Physics (PhysOrg.com) — Computer and television displays made using flexible, bendable polymer materials are technologies of the future, promising roll-up computer monitors and other innovations. Scientists are making progress toward bringing these technologies into our homes and offices. A research group at Seoul National University in Korea recently created a flexible polymer transistor that is printed using a simple process involving ultraviolet (UV) light, described in the November 20 online edition of Applied Physics Letters. Creating transistors in this way is an important avenue toward flexible electronics, as transistors form the basis of most modern electronic devices. Computer processing chips, for example, consist of more than 200 million transistors.”Our printing method is low-cost and could be scaled to the manufacturing level — a requirement for most technologies,” said Hong Lee, the paper’s corresponding author, to PhysOrg.com. “It performs as well as non-flexible polymer transistors and better than similar transistors produced by other research groups.”The researchers started with a commercially available polymer mold etched with a “source-drain” pattern, forming locations for two of the three electric terminals that make up a transistor: the source, drain, and gate. They then coated the mold with a very thin layer (just 100 nanometers) of a conducting polymer material, known in abbreviated form as PEDOT.Next they coated a flexible substrate — a surface on which to build the transistor — with a “pre-polymer” liquid layer. The pre-polymer is key to the process because it hardens and binds to the PEDOT layer when illuminated with UV light.Applying no pressure, the researchers brought the mold and the substrate into contact and exposed them to UV light for 20 minutes. When the mold was removed, the researchers saw that the PEDOT on the mold’s raised areas had been transferred to the substrate, forming the transistor’s source and drain.But unlike ink deposited onto paper by a stamp, in which the paper’s surface remains flat, the substrate underwent topological changes caused by the physical bonding between the pre-polymer and the PEDOT under the UV light during the hardening process. Where the raised parts of the mold met the substrate, the substrate’s surface developed “low” areas. And across from the mold’s low areas, the substrate developed a raised mound between the source and drain, which acts as a channel between them.The substrate was coated with two additional polymers, an “active” current-carrying layer and a dielectric, a material used in transistors to control the flow of current.Finally, the substrate was flipped over and put in contact with PEDOT-coated glass. PEDOT “ink” was transferred to the substrate’s raised area, completing the four-layer printed transistor structure.This method departs from the inkjet-style approaches commonly used to print polymer transistors, in which a printer head moves back and forth across the substrate, depositing the polymer layers in tiny droplets. Inkjet printing has been successful, but ensuring the overall transistor pattern is properly aligned before the ink is dispensed can be difficult. The UV method does not require this step because the formation of the raised mound after the mold and substrate are combined and illuminated acts as a self-alignment mechanism.Citation: Applied Physics Letters 93, 203308 ( 2008) link.aip.org/link/?APPLAB/93/203308/1Copyright 2008 PhysOrg.com.

Sony TVs show highend color via quantum dot tech

first_img Citation: Sony TVs show high-end color via quantum dot tech (2013, January 15) retrieved 18 August 2019 from https://phys.org/news/2013-01-sony-tvs-high-end-quantum-dot.html “By integrating QD Vision’s “Color IQ” optical component with Sony’s unique display technologies, our Bravia television sets achieve significantly wider color gamut, that provides a far more natural and vivid viewing experience,” said Masashi Imamura, President, Home Entertainment and Sound Business Group, of Sony, in a press statement. QD Vision’s technology works with major LCD applications, including LCD TVs, LCD monitors and mobile displays. The technology harnesses the unique light-emitting properties of quantum dots, which is a class of nanomaterials. The approach used by QD Vision increases the range of colors that an LCD television can display by about 50 percent, allowing for purer colors. QD Vision describes itself as a nanomaterials product company delivering advanced display and lighting solutions, and it has been working to commercialize the technology advances it made at MIT some years ago. Its edge is as, in its words, “the only quantum dot company solely focused on displays and lighting.” The co-founders have worked on their technology along with scientific advisors, MIT professors Vladimir Bulovic and Moungi Bawendi, who the company said ” is considered the father of quantum dot technology.” Bawendi’s work has been focused on uses for quantum dots as alternatives to fluorescent organic dyes and proteins for labeling, imaging, and monitoring biological systems and for better understanding and battling cancer.Technology Review, explaining how QD Vision technology translates into a Sony TV viewing experience, noted how in LCD televisions, each pixel is illuminated from behind by a white backlight, and different colors are created by changing the amount of light allowed to pass through three different filters. QD Vision’s technology eliminates the white backlight and uses quantum dots to enhance the backlight. It starts with a conventional blue LED, which produces pure blue light. The blue light stimulates two kinds of quantum dots that emit pure green and pure red. This document is subject to copyright.

PBS stares back at 18gigapixel ARGUS drone imaging system

first_img © 2013 Phys.org Explore further More information: www.pbs.org/wgbh/nova/military … e-of-the-drones.html (Phys.org)—Described as the next generation of surveillance, and representing the world’s highest resolution camera, the ARGUS-IS, which stands for Autonomous Real-Time Ground Ubiquitous Surveillance Imaging System, is featured on PBS’ NOVA program on drones, which describes the latest technologies behind drones. The program carries a demonstration of the imaging system, which is the result of development work at BAE Systems, a defense, security and aerospace company. The BAE team developed the ARGUS-IS array as a project funded by the Defense Advanced Research Projects Agency (DARPA). The importance of this surveillance imaging system centers on its unprecedented capability in finding, tracking and monitoring events in real time. The system was demonstrated by Dr. John Antoniades, technical group director for Intelligence, Surveillance and Reconnaissance Exploitation Technologies at BAE. The demo was part of the NOVA episode “Rise of the Drones.” He did not show the real Argus sensor because it is classified. Antoniades said the government, however, gave permission to discuss its basic capabilities. He made reference to the system having the world’s highest resolution camera, which can be attached to the belly of a UAV. Flight-tests autonomous multi-target, multi-user tracking capability Citation: PBS stares back at 1.8-gigapixel ARGUS drone imaging system (2013, January 29) retrieved 18 August 2019 from https://phys.org/news/2013-01-pbs-gigapixel-drone-imaging.html With its capabilities, the system can detail areas within a very broad context, with enough zoom power to see people waving their arms and walking around in parking lots. This is a 1.8-gigapixel video surveillance platform that can resolve details as small as six inches from an altitude of 17,500 feet. He said its imaging power involves basic cellphone technology. The BAE team decided to string together 368 imaging sensors focused on the ground via image-stabilized telescopic lenses. In this manner, the ARGUS-IS array links together images to perform surveillance over enormous terrain in realtime.In February 2010, after completing a flight test of the ARGUS-IS, Dr. Steven Wein, BAE director of optical sensor systems, spoke of its technical edge over previous work in imaging systems. “Very high-resolution imaging systems required for vehicle and dismount tracking typically have a ‘soda-straw’ view that is too small for persistent coverage. Existing wide-area systems have either inadequate resolution or require multiple passes or revisits to get updates.” He said that the ARGUS-IS system overcomes the fundamental limitations of current airborne surveillance systems.In 2007, BAE Systems received an $18.5 million contract from DARPA to develop a new class of intelligence, surveillance, and reconnaissance systems and capabilities.

Researchers study kinematics of the supernova remnant G109110

first_img(Phys.org)—A team of astronomers from Mexico has lately conducted a kinematics study of a supernova remnant in the Milky Way galaxy known as G109.1-1.0 (or CTB 109). The new research reveals crucial insights into basic properties of this remnant. The findings were presented Sept. 23 in a paper published on the arXiv preprint repository. Search for stellar survivor of a supernova explosion Supernova remnants (SNRs) are diffuse, expanding structures resulting from a supernova explosion. SNRs contain ejected material expanding from the explosion and other interstellar material that has been swept up by the passage of the shock wave from the exploded star. Studies of supernova remnants are important for astronomers as they play a key role in the evolution of galaxies, dispersing the heavy elements made in the supernova explosion into the interstellar medium (ISM) and providing the energy needed for heating up the ISM. SNRs are also believed to be responsible for the acceleration of galactic cosmic rays.G109.1-1.0 is one such remnant located in the Milky Way’s Perseus arm. Previous observations of this SNR revealed that it has a semicircular shell-type morphology. However, the astronomers have not yet definitely determined basic properties of this remnant, such as its distance, age and the amount of energy deposited in the interstellar medium in result of the explosion. Various studies produced significant discrepancies in the results.Recently, a team of researchers led by Mónica Sánchez-Cruces of the National Polytechnic Institute in Mexico City has studied the kinematics of G109.1-1.0, which allowed them to diminish the uncertainties presented in previous papers. Their research is based on observations carried out in June 2015 with the use of a scanning Fabry-Perot interferometer known as PUMA. The instrument is installed on the 2.1 m telescope at the National Astronomical Observatory in Sierra de San Pedro Mártir, Mexico.”We obtained a set of direct images in Hα and [SII]λλ6717,6731 Å using the PUMA focal reducer without the Fabry-Perot interferometer in the instrument optical axis. The exposure time of each of the direct images was 120 s. We also obtained [SII]λλ6717,6731 Å Fabry-Perot data cubes of two regions of the SNR CTB 109,” the paper reads.By analyzing the new images, the astronomers found that the distance to G109.1-1.0 is about 10,100 light years, which is consistent with one study published in 2012. When it comes to the age of this remnant, the researchers calculated it to be between 9,000 and 9,200 years.Furthermore, the authors estimated the initial energy deposited in the interstellar medium by the supernova explosion. According to the research, this value lies between 180 and 520 quindecillion erg.The scientists concluded that the remnant’s relatively young age and the amount of energy deposited in the ISM, indicate that G109.1-1.0 contains simple pulsars. “The age is of thousands of years and the (E0) is rather typical of SNRs containing simple pulsars,” the authors wrote in the paper.Besides determining these basic parameters, the team also found that the remnant’s systemic velocity is approximately –50 km/s, while its expansion velocity equals some 230 km/s.

Take a bow Tiesto

first_imgThe last leg of Sunburn Arena came to a close in the city with DJ Tiesto playing for a packed ‘field’. And what a performance it was! And though we must mention that the horrors of terrible parking and long lines can be forgotten for the two hours of absolute crazy EDM and the sky touching energy levels at the concert – we do wish we had a little more of the man!The 3-city tour covering Mumbai, Bangalore and Delhi was only the music icon’s second trip to the country in almost a decade. The World No. 2 did not disappoint,pulling off an adrenaline pumping set that brought down the house bringing an electrifying end to the season-ending. Also Read – ‘Playing Jojo was emotionally exhausting’Shailendra Singh, the man behind Sunburn spoke about the growing popularity of EDM in India – the moot reason for a concert like this to function so well – ‘The magic of EDM is the music need not have words. In a multi-lingual and multi-cultural country like ours – that is truly the kind of music that can be understood and enjoyed by all,’ he feels.DJ Tiesto spoke to Millennium Post about what he does best – drive the crowds wild. ‘India is great! Each country is unique but India has great fans with tons of energy. This is my second time in India. I came here back in 2008. I really like India, it has a very distinctive culture,’ says the DJ. So where did the music mania come from? ‘I grew up in Breda. We’re all influenced by our surroundings and Holland had a big influence on me. There are so many great producers and DJs from Holland, so kids look up to them. As a teen I used to listen to a lot of rock music. Def Leppard, Van Halen, Iron Maiden to name a few. Later started DJing for local house parties in my teens,’ he explains. Also Read – Leslie doing new comedy special with NetflixAnd the biggest moment for Tiesto? ‘Performing at Olympics  is one of the memorable experience along with a lot of other amazing performances. I played on the beach in Rio De Janeiro for over 250,000 people which is another gig I can’t forget!’ comes the pat reply!For our ears only, how is Tiesto off the console? ‘I don’t really concern myself so much with titles. I focus on making music, my shows and the fans. I love sports so that’s always a great way for me to unwind,’ says the man and we are all smiles!last_img read more

To the hills we say

first_imgNestled between the hills, Arunachal Pradesh is a traveller’s paradise. Long trails, waterfalls, fantastic architecture, the state is something to behold. Arunachal Pradesh Tourism Minister Sonam Chambey was in Delhi recently and we caught up with him for a candid conversation and he explained why Arunachal must top our list of next holiday destinations and also what lies next on the to-do list. Here are excerpts of the interview.What steps have you taken to increase tourism footfall in Arunachal Pradesh? Also Read – ‘Playing Jojo was emotionally exhausting’The only way to improve tourist footfall is to increase awareness of the destination among the potential tourists. Arunachal Tourism has been making consistent efforts in marketing and promotion by way of participation in major travel fairs, ads in popular magazines etc.Furthermore, to make the stay of the tourists in the state more enjoyable and memorable one, efforts are being made to popularize unique tourism products such as rural/tribal way of life, kiwi farm and apple/orange orchard tours etc. Also Read – Leslie doing new comedy special with NetflixWhich places/activities are you promoting within the state?Arunachal Pradesh is a destination, which has something to offer for everyone!  Adventure seekers- white water rafting, mountaineering, trekking, river crossing, mountain biking etc. A treasure trove of culture and heritage- distinct culture and traditions of more than 26 major tribes and over 100 sub- tribes. Spiritual destination with 400-year-old second largest Buddhist monastery in the world, Hindu pilgrimage such as Parasharam kund, Bhismaknagar and Malinithan With 82% forest cover teeming with life, a bio-diversity hotspot with unique flora and fauna is an ideal destination for nature lovers. Niche products such as angling, bird watching, and wellness are also being promoted. We are also planning to sell the state as a destination for creative people- writers, painters, lyricist etcWhat is the kind of tourist footfall seen over the years? Does AP see many foreign tourists as compared to Indians?Arunachal Pradesh is emerging as a favoured destination for tourists. We are witnessing steady flow of both foreign and domestic tourists and the footfall has been increasing over the years. The percentage increase is very encouraging.What kind of development are you looking in for in the state to make travel easier for the tourists?Massive infrastructural development projects such as the Trans-Arunachal Highway, Railways, Airports etc are making rapid progress and will be commissioned shortly. With completion of these projects, travel for tourists will ease to a great extent. Large number of hotels, home stays have come up and many more are coming up to address the accommodation demands of the tourists.You conducted the International Tourism Mart, in January this year; can you tell us the purpose behind it and the response you got from the mart?The ITM in January was held in Guwahati in which Arunachal tourism also participated. It has been a revolutionary initiative of the ministry of tourism. This has put the entire region on global focus as a tourist destination. Arunachal Tourism in particular has reaped a lot of benefits from ITM. The state tour operators have had excellent networking sessions with both domestic as well international buyers and I am certain that this season will see them getting increased business.Arunachal Pradesh was awarded the most favourite upcoming tourist destination by a popular magazine recently; can you tell us what makes AP a unique tourist destination?Arunachal is the largest state in North East India. The geographical diversity of the state with the foothills, hills and the mountains and its distinct flora and fauna, coupled with as many as 26 different tribes, each with separate culture and history makes it a unique destination. With options from adrenaline rushed adventure to relaxed holidaying in the lap of pristine nature, tourists coming to Arunachal are guaranteed a wholesome and a unique experience.last_img read more

A winter of Chetans discontent

first_img‘It doesn’t exist! No one knows about him here!’ I mumbled to myself as I looked around the bookstore at Frankfurt airport. The train to Wuerzburg and then the shop at the university library.  Deliriously happy. Yes. The on-campus store had F Scott Fitzgerald, William Shakespeare, George RR Martin, Robert Galbraith and before I could grant them intellectual snobbery – there was a Stephanie Meyer too  and I think I spotted a Nicholas Sparks. No Chetan Bhagat. I had left that horror back in Delhi and didn’t get assaulted with people reading it in Dubai. Also Read – ‘Playing Jojo was emotionally exhausting’‘No one’s heard of him here!’ I exclaimed, thoroughly confusing the guy who was helping me around with my registration process (which took one hour – Indian colleges take note please!). I of course then had to explain to him who this guy was and why we (the wannabe intellectuals) love to hate him. Over schnitzel and fries (I had to cliché it up a bit) I told this unsuspecting gentleman about Mr Bhagat. About Five Point Someone, Three Mistakes of My Life, 2 States, One Night at a Call Centre and finally halting at Half Girlfriend. I also pointed out that the movies were exponentially much better than the books and simply because those had very little to do with the author. Just as one of the ‘Indian’ guys here called Honey Singh the Indian Snoop Dogg, I tried in vain to find a worthy equivalent. Also Read – Leslie doing new comedy special with NetflixAnd that got me thinking. Chetan Bhagat is wholly and thankfully only an Indian phenomenon. The ‘appeal’ of his Rs 195 do not cross over borders unless someone takes the book with them on an international flight. Maybe we should try adding it to the list of illegal items like knives and explosives.Stephanie Meyer, EL James crossed the Atlantic. Bhagat has not made it across a few countries, yet. And I will call this a good thing. While Bhagat has managed to capture an incredible reading audience and has an enviable business model well in place, he has people who read him to loathe him and he has people who read him and go – ‘Oh yes! He knows, he knows how I feel!’ *Sniff* As an author he has played this game better than most of his colleagues. Neel Mukherjee cannot boast of such sales figures, he perhaps never will. He writes about college canteen issues that only we Indians can gorge on to the point of getting sick. Some regurgitate that into rants such as these, some gorge some more. The issues are uniquely and obstinately rooted to the soil – Bhagat takes on IIT, IIM, inter-cultural marriage, 2002 Gujarat riots, Call Centres and in his latest book what can be best described as ‘Biharis-do-not-know-English-and do-not-care-to-learn-till-Bill Gates-can-come-to-save-a-village-school’ aka ‘Wanting-to-date- a-Delhi-rich-is-a-bitch’. Not the communist burden, neither the diasporic problem and never the brave new world. Bhagat is perhaps ill-equipped to take on tropes that matter and it works very well because we, in our domestic help accelerated world, don’t allow too much mind space to such world issues. Prices of onions are more intrinsic and real.Unfortunate. But look at the wonders it did for Bhagat. It is the whole classic ‘us and them’ case which will have the intellectuals ruing the success of this man while the others buy his book anyway.Over the last five years in India, we have had the metro reads phenomenon rearing its ugly head. Describing a series of books that can be read over an hour or a little more (a little less than the time needed to travel from Noida to Dwarka) while one travels. These books aren’t Booker or Pulitzer worthy – never will be. They do not require an ‘intelligent’ mind, they are just in your hands to distract you from the sardine crowd and the lack of deodorant.Bhagat is more the Indian Railways and domestic flight read. Giving the man his due, Bhagat got a huge chunk of the population to read, he got them interested in books again and while it is horrible that these people read (and enjoy) this level of story, plot and language – it is also commendable that he managed this – Rupa owes this man a good few limbs.However, driving the rant home – talking Neil Gaiman and Umberto Ecco with ‘colleagues’ in the department, I sighed in relief that they will not have to fight the battle of bad authors on this continent quite yet and they would not equate Indian writings with the Bhagat phenomenon.But winter is coming. I could tell them his books are excellent replacements for wood.last_img read more

Cong spared Reliance SEZ of Rs 50cr fine Haryana Min

first_imgAs Opposition leaders raised the Reliance SEZ issue in the Assembly on Tuesday, State Finance and Industries Minister Abhimanyu said the then state government had entered into a MoU with Reliance Industries in 2005 to set up the Special Economic Zone in the Gurgaon-Jhajjar region.“A MoU was signed between HSIIDC and Reliance Ventures Limited on December 12, 2005. Based on the decision of the Haryana Cabinet, HSIIDC signed a Joint Venture Agreement (JVA) with Reliance Ventures Limited on June 19, 2006, for setting up a multi product SEZ over an area of 25,000 acres in Gurgaon-Jhajjar. Also Read – Need to understand why law graduate’s natural choice is not legal profession: CJI“However, it was later decided to shelve the SEZ project and JVA was terminated on August 29, 2014,” Abhimanyu said, while adding that the previous Congress government had promised “lakhs of jobs” and huge investment in the state from the project. To questions raised by some independent and INLD MLAs, Abhimanyu informed the House that “no tender/competitive bidding process was followed in firming up the project, but a MoU was signed between the two parties….” The minister further stated that many decisions regarding the Reliance SEZ project were taken by the Council of Ministers of the previous Congress government and some even outside the knowledge of the State Cabinet. He also said that Reliance Industries had returned nearly 1,384 acres of land in Gurgaon that was acquired for its SEZ.

Space constraint delaying work on foot overbridges Sovan

first_imgKolkata: Mayor Sovan Chatterjee said on Monday that space constraint has delayed the construction of foot overbridges in the city, which have been planned to curb accidents.Responding to a poser from BJP councillor Tishta Biswas (Das) of ward 86, regarding stoppage of work in a couple of foot overbridges on Gariahat Road and in front of Ballygunge Siksha Sadan at the monthly session of KMC, Chatterjee said, “The foot overbridges that we have proposed to construct will have escalators, along with other modern amenities to facilitate the movement of pedestrians. This requires a reasonable amount of space.” Also Read – Heavy rain hits traffic, flights”We are in constant touch with Kolkata Police and are holding meetings on a regular basis to overcome this paucity of space, which has resulted in delay of work. We are hopeful that things will be sorted out soon,” Chatterjee said.It may be mentioned that KMC is facing problems with space constraints not only at Gariahat Road and Ballygunge Siksha Sadan, but also at Exide crossing. The Mayor said that KMC and Kolkata Police have to ensure that construction of these foot overbridges causes no hindrance to the smooth flow of traffic in the city. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedIt may be mentioned that KMC has earmarked some spots in the city for construction of these foot bridges under PPP mode, for the safety of pedestrians. The places include – Deshapriya Park, Ballygunge Siksha Sadan, Gariahat Road, South City, Exide Crossing, Turf View Road and Alipore Zoological Gardens. The spots were selected on the basis of their proximity to frequent road accidents.However, KMC and Kolkata Police are worried that the foot overbridges existing in the city are severely underutilised. “Despite the presence of elevators in some of these FOBs, people hardly use them. So we have plans to put up guard rails on the divider to make people use them,” an official in KP’s traffic wing said.The civic body is also planning to take a tough stand to make pedestrians use the FOBs. “We will urge KP to impose fine to the extent of Rs 2,000, to curb this practice,” a senior KMC official said.last_img read more

PCB rules out immediate return of tainted duo

first_imgThe Pakistan Cricket Board has ruled out an immediate first-class return for the tainted duo of Salman Butt and Muhammad Asif, saying that they would have to attend further anti-corruption rehabilitation programs to regain the PCB’s trust.Najam Sethi, Chairman of the PCB’s influential executive committee, said the Board had planned special rehabilitation programs for the two players whose spot-fixing bans expire on September 1, allowing them to return to cricket. Sethi revealed that there were lots of players including some members of the Pakistan team, who were not happy that Butt, Asif or Mohammad Aamir should be rehabilitated back to top cricket. “I don’t think they have to go into first class cricket straightaway when the ban ends. They will have to attend the rehabilitation program of the PCB for two to three months,” Sethi said on Geo Super channel. “We had written to the ICC seeking clarification on some points and they have in reply left it to the PCB to complete the rehabilitation process of these players.” Also Read – A league of his own!Asked about the players who were not happy to see the tainted trio coming back, Sethi declined to take names but said even former Test captain Ramiz Raja had mentioned this in a recent column. “Obviously we have to talk to these players, convince them and give them time to develop trust once again in the players coming back. The PCB itself needs to be very sure that they wouldn’t repeat the past because what happened in 2010 in England was very embarrassing and damaging for Pakistan cricket,” Sethi said.  Also Read – Domingo named new Bangladesh cricket coachPCB to launch logo of long-awaited PSL next monthThe Pakistan Cricket Board said it would launch the official logo of its much-delayed Twenty20 Super League on September 19. A top official, however, said a decision on the venue for hosting the five-team franchise tournament would be taken in two weeks time.“We have two options either hold the PSL as planned in February in Doha or wait until April and host it in Dubai and other venues in the UAE,” he said. He said a recent visit to Dubai to meet the officials there to discuss the use of venues had failed to yield results since in February the Masters championship was being held in Dubai. “They have given us the option of hosting it in April. Our delegation also went to Qatar where their national Olympic committee and cricket association were very welcoming and keen to host the PSL.“Qatar is staging major international events now but cricket has remained out of their calendar but now they want cricket as well and their officials assured us they would offer all cooperation and help to make the PSL a big success in Qatar,” the official said. “Their Olympic committee and cricket association also told us they have got government permission to have the PSL with us,” he said. The PCB official also ruled out any chances of the PSL being put off for a third time in three years’ time.last_img read more
