The content is provided for information purposes only. Researchers from Harvard University and the University of Hawaii at Manoa recently announced a new method for organizing nanowires and carbon nanotubes across large areas: blowing bubbles. Bubble blowing, or blown-film extrusion, is a well developed technique used in industry, such as in plastic-film manufacturing, where polymers are melted and inflated into balloons that can be collapsed and cut. However, this is the first time that this approach has been used in nanoscience research. The scientists suspended each type of nanostructure in a polymer-based liquid and created large bubbles using a circular die and controlled pressure. The very thin wall of each bubble (a few hundred nanometers thick) contains an even, well organized and aligned distribution of nanostructures. When an expanding bubble is placed against a surface, the bubble wall is transferred to it. This allows a thin film with a controllable nanostructure density and pattern to be deposited onto relatively large wafers, plastic sheets, and curved surfaces.“This ability is necessary for many proposed optical and electronic applications for nanowires and nanotubes but, so far, other methods cannot be extended to the large-scale assembly of nanowires and nanotubes on both flexible and rigid substrates,” said Harvard scientist Charles Lieber, the paper’s corresponding author, to PhysOrg.com.Lieber and his colleagues worked with two types of nanowires – silicon and cadmium sulfide – and both single- and multi-walled carbon nanotubes. In each case, they were able to produce bubbles with diameters greater than 25 centimeters (cm) and heights greater than 50 cm. The films were transferred to various surfaces: a silicon wafer 20 cm in diameter, a flexible plastic sheet with dimensions of 22.5 cm x 30 cm, and a half cylinder 2.5 cm in diameter and 6 cm long.The researchers say that by using larger dies and learning how to gain greater control of the expansion process they could potentially create bubbles up to a few meters in dimension as is achieved in today’s plastic-film industry. This means that films larger than one meter across could be produced and transferred, opening up the potential of new large-area electronics applications using nanowires and nanotubes.Lieber and his colleagues illustrated this potential by using a silicon-nanowire blown-bubble film to create a large array of nanowire-based transistors on 7.5-cm-diameter plastic sheets. The transistors’ properties and performance compare to, and often exceed, those created using other assembly methods. By using higher performance nanowires, the scientists expect that significant improvements are possible.“Our method has the added advantage of being a more straightforward and efficient approach than other techniques in terms of making functional nanodevices over large areas,” said Lieber.The scientists do concede that the nanowire density and wire-to-wire distance of the silicon-nanowire film currently achieved are “modest,” but can be further increased by preparing a higher concentration polymer suspension of nanostructures. However, they say, those values are still useful for some applications, such as biological sensor arrays and display screens.This research is discussed in the May 27 online edition of Nature Nanotechnology.Citation: Guihua Yu, Anyuan Cao and Charles M.

Toshiba supersized glassesfree 3D TV steals IFA show

first_img More information: Press release (PhysOrg.com) — Toshiba earlier this week showed off its new no-glasses 55-inch 3-D TV. The company says it is the world’s first large screen 3-D TV that does not require any glasses. According to Toshiba, the new 55ZL2 is its most advanced television to date with the latest imaging technology. Toshiba chose the IFA 2011 event in Berlin, a high-profile trade show for consumer electronics and gadgets, as the venue to preview this supersized flat-screen television. With promotional showmanship, glasses were handed out at the press briefing with the words “bye bye” printed across the lenses.

A range of lenticular lenslets guides the images. A Quad Full HD display offering up to 3840 x 2160 pixel resolution enables an effective 3-D effect for up to nine viewers, where images are being presented to different positions throughout a room.Showcasing the TV’s features, Toshiba made special note of the new set’s face-tracking technology. This means that a camera below the screen can scan to see how many faces are in the room, with nine the limit. Faces are tracked so that the machine can adjust the images. The aim of face-tracking is to provide a 3-D experience no matter where the viewer is in the room. There are nine different optimal angles for good picture quality in the Toshiba set. The user pushes a button on the remote control, which activates the camera.The viewer can upscale 2-D content to 3-D. As part of the conversion, the Toshiba TV offers depth control to adjust the depth to the user’s liking. The TV will be available in Germany in December. The unit costs €7,999 euros, or about $11,400.The debut is viewed with interest by market watchers who note that the no-glasses 3-D advancement comes at a time of sagging television sales and heightened competition among TV manufacturers. Bells and whistles enhancing the viewing experience are ways in which the vendors can differentiate and improve sales. With this week’s debut, Toshiba has a lead over rival manufacturers still struggling to make 3-D television sales show better growth. Glasses-free viewing may change the tide of disappointing sales figures.last_img read more

NSF turns to ancient pottery to improve modern heat resistant ceramics

first_img Explore further (PhysOrg.com) — In order to better understand how ceramics are able to resist heat, the National Science Foundation has awarded grants totaling half a million dollars to three research groups to look into how the ancient Greeks made their pottery, a process which allowed for as many as 100,000 vases to survive from ancient antiquity to now – a period of some twenty five hundred years. The hope is that such research will reveal more about the nature of iron-spinel chemistry, which is what gives ceramics an ability to withstand heat while remaining chemically stable. Getting a better grip on how ceramics work is critical to future space flight technological efforts, as ceramics are used to help space vehicles withstand both extreme hot and cold temperatures. © 2011 PhysOrg.com Citation: NSF turns to ancient pottery to improve modern heat resistant ceramics (2012, January 4) retrieved 18 August 2019 from https://phys.org/news/2012-01-nsf-ancient-pottery-modern-resistant.html 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. Deciphering the elements of iconic pottery In order for space vehicles to work properly, they have to be able to withstand the cold of space, which can be as low as 250 degrees Fahrenheit below zero. Then, some vehicles have to be able to withstand the extreme heat of reentry, which can be as hot as 3000 degrees. Hot enough to melt most any metal. As most know, the Space Shuttle was fitted with ceramic tiles on its underbelly to keep the vehicle from overheating as it came back to Earth, which was made all the more apparent when damage to the tiles resulted in the loss of Columbia in 2003. But ceramics are used in other components as well, and will be needed as more ambitious projects are undertaken in the future. Equally important is the ability of ceramics to remain chemically unchanged when subjected to such temperature variations. Such properties allow for the construction of components that minimize expansion and contraction under such stresses, which can be critical for long term operations in space. This is why the NSF has turned to research scientists to see if the ancient Greeks can provide some insight.Such research will involve using something called x-ray absorption near edge structure (XANES) – which is a special type of spectroscopy, along with other types of x-ray techniques, to find out what has gone on with iron oxidation in the pottery under study. What’s needed is a better understanding of the molecular structure of iron minerals that were used to make the pottery to help researchers in designing newer and better types of ceramics for future space missions, whether manned or otherwise.What’s interesting is that it is apparently the degree to which the iron in the ancient ceramic pottery oxidized that caused the distinctive red and black colorations that made it so attractive to those that worked with it all those years ago.last_img read more

Ukraine team wins Imagine Cup with gloves that convert sign language to

first_img(Phys.org) — For about a decade, Microsoft has been running a competition called the Imagine Cup that rewards people for developing innovative ideas using Microsoft products. This year the competition was held in Sydney Australia, and the winner in the software category was quadSquad from Ukraine for a system they call EnableTalk; a truly unique and useful system that allows hearing impaired people who rely on sign language to communicate to those who can hear by employing a pair of sensor enabled gloves that are able to capture sign language gestures, translate them to text and then have the words spoken using a text-to-speech translator on a cell phone. For their efforts the team won $25,000 in prize money and likely the gratitude of millions once the gloves make it to market. The gloves work through the use of five hardware components: flex sensors in the gloves record finger movements and a main controller coordinates information from an accelerometer/compass, an accelerometer/gyroscope, a microcontroller and a Bluetooth module. Windows mobile software was used to convert the gesture commands to sound signals for broadcast by the Bluetooth module. The sound waves are converted to voice using Microsoft Speech and Bing APIs running on a Smartphone, which ultimately serves as the voice for the person using the system. The team, made up of members identified as AntonStepanov, MaxOsika, Scizor60 and mentor dmitrtys, told the audience watching the demonstration of EnableTalk that the whole thing costs only about $50 per system (not including cell phone) and that they believe it could be brought down to $20 when mass produced. Conventional systems meant to pull off the same feat, but offer less sensitivity, typically run into the thousands of dollars. This document is subject to copyright.

They also noted that the system can be easily tweaked by the user to incorporate custom signs and thus can be used for virtually any sign language dialect. The point they say is to help those with hearing impairments better manage in the world of the hearing. The problem with sign language they point out, is that most people who can hear never learn it, thus those with hearing impairments are only able to communicate with a small part of the general population which generally includes those who cannot hear and those in their immediate circle. This new system they say, will allow those with hearing impairments to communicate with anyone.last_img read more

Crowd sourcing project to allow 3D scantoprint web app

first_img © 2013 Phys.org Citation: Crowd sourcing project to allow 3D scan-to-print web app (2013, August 5) retrieved 18 August 2019 from https://phys.org/news/2013-08-crowd-sourcing-3d-scan-to-print-web.html Explore further Technology to allow for printing three dimensional objects is evolving rapidly, making it difficult for some to keep up. It’s also still relatively expensive. Currently, people who wish to print such an object have but two choices—buy (or borrow) a 3D printer or contract out with a company that prints 3D objects for a price. Both options require software and a depth camera. Now it appears a third option is about to make its debut—one that might make the entire process both cheaper and far easier to carry out. BotObjects announces first full color 3D printer— ProDesk3D Volumental, a company that is currently accepting image data captured via depth camera, printing 3D models and shipping them back, is now looking to create a web based app to replace the software portion of the process. That would mean anyone with a depth camera (which includes Kinect devices) could scan an object, have it rendered onscreen and then sent to a 3D printer of their choice. If successful, a new way to print 3D objects could become as common as printing text and images on a piece of paper. The company has set up a Kickstarter project with a goal of reaching $20,000 to finish writing the web app code—pledges so far are just over half that amount.As depth cameras (those with two or more lenses) become more common, demand for 3D printing grows, though currently printers able to do so are still quite expensive. If, however, consumers that have already purchased a Kinect device for gaming can use their existing equipment along with what is essentially free software to capture the object data, then half the process of producing 3D models is covered. An added advantage to such a system would be a reduction in difficulty in capturing the 3D image. Users could conceivable load the browser scanner, spin slowly in place in front of their Kinect device, place an order with Volumental (or have the data sent to another site, such as the local 3D printer at work) and wait for the full color model to arrive at their home. Objects captured would be limited only by the range of the camera—users could conceivably scan every object in their living room, including furniture and have it printed in a size limited only by the ability of the printer to which it is sent. As printer technology improves, so too will the range of materials that can be used as “ink” opening up the door to some pretty amazing possibilities. This document is subject to copyright.

LG Chem turns to stepped curve and cable batteries

first_img Explore further There are three types of batteries on the LG Chem product map, and these are the stepped battery, the curved battery and the cable battery, the latter to be ready in the next few years. What they all share in common is the company’s eye on innovative product opportunities that will spring up all over the place once flexible displays take hold in the marketplace, to be applied toward phones and a wide range of wearables including watches and glasses. In turn, LG Chem has worked up alternatives to the rectangular-shaped battery.The curved battery packs are to power mobile devices with curved screen or flexible designs such as smart phones, watches and glasses. Using a”Stack and Folding” technology, the company’s batteries achieve a curved design. They will power LG Electronics’ next phone lineup.The stepped battery refers to an approach where two batteries are added on top of each other in the form of a step design. The battery takes greater advantage of available space in the device, filling up dead space to fully power the handset and increase battery capacity. LG Chem plans to take the approach further, stacking up more batteries depending on customer requirements.The cable battery travels into more ambitious territory, to be adapted for innovative devices that are not only bendable and wearable but can even be tied into a knot. The cable battery will also have waterproof features.According to a report in The Korea Times, LG Chem is preparing to sell curved batteries to other smartphone vendors than just LG Electronics.Researchers see the flexible display market as set to grow quickly with the upcoming launch of innovative, curved devices. Curved displays can accommodate bendable designs, in turn to expand beyond phones into automotive displays, tablets and wearables. Credit: LG (Phys.org) —Stories have been rolling in from technology news sites this week about vendors in a race to debut curved smartphones and flexible OLED panels for smartphones. Also making news on Tuesday is Seoul, South Korean-based chemical company LG Chem, which has curved batteries in production. The company, which is a major lithium-ion battery manufacturer, on Tuesday said it has curved batteries in mass production, and in fact has been producing curved batteries since July this year, at a plant in China.

Dress to impress No we dont

first_imgHow do you define sexiness? What is sexy?, ‘From an infectious smile of  Madhu Bala to the poised grace of Zennat Aman; dancing swirls of Madhuri Dixit and to the zero figure of Kareena Kapoor, everything is sexy! It has nothing really to do with how they dress up,’ said fashion critic and journalist, Reena Dhaka during a discussion in Oxford bookstore.‘Is being sexy anti-sexist?’, ‘Does dressing up in a sexy manner define a woman’s mindset?’ were some of the pertinent questions that were raised during the engaging conversation. An audio-visual presentation seeking responses from various women with different backgrounds attempted  to answer these questions. They all were asked one question and that was, if they dress-up for others? The unanimous answer was an outright ‘No’. Also Read – ‘Playing Jojo was emotionally exhausting’The discussion attracted quite an ethusiastic crowd who were of the opinion that they dressed-up for themselves and no one else.The key speakers of the conversation,  fashion designer, Rina Dhaka and Vinita Dawra Nangia discussed how dressing-up sexily does not really mean that one is easy or available. Nangia further said, ‘To even ask such a question would hint at sexism.’ The rape victims in this fairly sexist society are often slapped with a counter-argument as to how they deserve what hapened to them because they asked for it. When you ask them how? They will promptly reply with, ‘Of course, because of the clothes they wore.’ No one asks for violence, no one wants to get beaten up or raped, no matter what you wear. Also Read – Leslie doing new comedy special with NetflixDhaka said being a woman she has to confirm to various roles in a day and is expected to dress aprropriately for all the ocassions. She asked, ‘How can you expect a woman to dress appropriately throughout the day for varied ocassions. Isn’t that hectic? To dress three to four times a day? Just because people think it’s inappropriate to step out in a dress outside in the public?’ She said that dressing-up has nothing to do with sexiness. The definition has changed. It’s all in one’s attitude and the way they feel they are, not the way they dress. However, Dhaka’s ‘When in Rome, do like Romans’ comment did not strike well. She said, ‘In India,  it is very important to select a dress according to the place and environment. There is no harm in carrying a shrug or a scarf, which you can easily take off once surrounded with a like minded people.’ The question this comment raises and remained unaswered was,  why does one need to carry a scarf around? Instead of being preventive, why can’t we strive to change the mindset which compels us to carry a scarf with us?last_img read more

Monochrome visions

first_imgFrequently we find students claiming themselves to be ‘film buffs’, but do they really know about films? While they beat their own drums to label themselves as movie buffs, some film admirers beg to differ.“Young people should be sensitized about good films, to begin with. Once they are exposed to good international and national cinema, they’ll understand the value of films,” says, Ranjan Ghosh, director of Hrid Majhare, a Bengali film. “The idea that black and white movies are boring has developed because young uninitiated students have been shown works of the masters, for which they were still not ready,” adds Ghosh. Also Read – ‘Playing Jojo was emotionally exhausting’Outstanding films go unwatched by the self proclaimed movie enthusiasts. Rather films with mindless drama and commotion find place in the must watch list of these ‘movie buffs’. Most youngsters tend to stick to their preferred genre rather than exploring the vast expanse of cinema, yet claim to be movie maniacs. Classics have been listed over the years, but among them the black and white films go mostly unnoticed by the present youth as they identify the monochrome films to be ‘boring’. There are several interesting black and white films, both products of Bollywood and Hollywood, which comprise of both full length feature films and shorts films.  Also Read – Leslie doing new comedy special with NetflixCultures have changed over the years and so have the movies. Yet some ageless masterpieces rule the must watch list for movie addicts. But are the young minds aware of the ageless black and white cinema or are they looking out only for the recent quality films?Pradipta Bhattacharyya, director of Bakita Byaktigoto, winner of the best feature film in Bengali at the 61st National Film Awards, believes that people these days are more aware of films and they do understand movies better than what people used to do a decade ago. He suggests some black and white must watches for film enthusiasts—Battleship Potempkin(1925), films of Charlie Chaplin, films of Akira Kurosawa, Jean Renoir, Federico Fellini, and Citizen Kane (1941) from around the world, and masterpieces of Satyajit Ray, Mrinal Sen, Ritwik Ghatak, Shyam Benegal, Guru Dutt and Bimal Roy. “I was especially inspired by Ray’s Pather Panchali and it is undoubtedly one of my favourite films of all time,” says the director. Actor Aryann Bhowmik (Detective Byomkesh Bakshy fame) said, “Bringing out the colour from just Black and White is some serious and exciting art that I have always admired.” Kartikey Tripathi, an actor and screenwriter thinks that if people can understand the basics of film studies then they can understand its value too. “Listing good monochrome movies will be limiting the periphery of the movie world. If black and white films are boring how come we all have watched the likes of Casablanca and Psycho every time we got the chance of watching it?” adds Tripathi.“I feel monochrome is even better than colour. An expression or a feeling can be best explained by it. Monochrome has a crazy expressive tone. Some of my personal favourites are Orson Welles’s Citizen Kane, John Ford’s Stagecoach, Charlie Chaplin’s Modern Times and Mani Kaul’s Uski Roti” said Uppanishad Ghosh, a recent pass-out from the Department of Film Studies, Jadavpur University. Meghan Hooper, an ex-student of New York Film Academy says, “I think that it should be compulsory for movie lovers to watch and know at least one movie from every genre.” Her favourite monochrome films have been His Girl Friday and Holiday Inn.A suggestive tiny list of some very interesting monochromatic films would inspire young film enthusiasts:It’s a Wonderful Life(1946), Bicycle Thieves(1948), Rashomon (1950), Roman Holiday (1953), 12 Angry Men (1957), 400 Blows(1959), Psycho(1960), An Occurrence at Owl Creek Bridge (1962), Do Bigha Zamin(1953), Pyasa(1957), Mughal-e-Azam(1960), Dosti(1964).last_img read more

A high sense of purpose in life lowers death risk

first_imgPeople who have a higher sense of purpose in life are at lower risk of death and cardiovascular diseases, says a study.“Possessing a high sense of purpose in life is associated with a reduced risk for mortality and cardiovascular events,” said one of the researchers, Randy Cohen from Mt. Sinai St. Luke’s-Roosevelt Hospital, New York. The findings suggest that approaches to strengthening a sense of purpose might lead to improved health outcomes. The researchers pooled data from previous studies evaluating the relationship between purpose in life and the risk of death or cardiovascular diseases.  The analysis included data on more than 136,000 participants from ten studies—mainly from the US or Japan. Also Read – ‘Playing Jojo was emotionally exhausting’The US studies evaluated a sense of purpose or meaning in life, or “usefulness to others”. The Japanese studies assessed the concept of ikigai, translated as “a life worth living”. The study participants, average age 67 years, were followed up for an average of seven years.  During this time, more than 14,500 participants died from any cause while more than 4,000 suffered cardiovascular events such as heart attack or stroke.The analysis showed a lower risk of death for participants with a high sense of purpose in life. A high sense of purpose in life was also related to a lower risk of cardiovascular events. “Together, these findings indicate a robust relationship between purpose in life and mortality and/or adverse cardiovascular outcomes,” the researchers wrote. The study appeared in Psychosomatic Medicine: Journal of Bio-behavioral Medicine.last_img read more
