A report from the Environmental Integrity Project (EIP) says regulators in Texas and Louisiana have approved 31 new plants – or plant expansions – along the coast over just the past two years. The report says the two states have approved more than 70 such projects since 2012.“A lot of these are being built in flood zones, where inevitably there’s going to be storm surges,” says Tom Pelton, an EIP spokesperson.Environmental groups say companies need to do more to bolster these plants against the more-intense storms climate change is expected to cause.There are signs that the industry agrees: after Hurricane Harvey, some plants in the Houston area looked at whether their “worst case scenarios” for storm planning will be good enough down the road.

This material may not be published, broadcast, rewritten or redistributed in whole or part without the express written permission of PhysOrg.com. In their study, Pradip Ghosh of the Nagoya Institute of Technology and his coauthors have demonstrated how to fabricate CNCSs on a transparent, flexible substrate at room temperature. The resulting CNCS-based electron emitter could then be used as a field electron emission (FEE) source for transparent, flexible field emission displays (FEDs). FEDs are a new kind of flat panel display that have several advantages, such as high contrast and lower power consumption than liquid crystal displays (LCDs). However, making FEDs transparent is very difficult since field electron emission requires a very high electric field and operation voltage. In order to achieve this high voltage, researchers usually use surfaces with a rugged sharp tip structure since the electric field is enhanced around the tip regions, enabling the operation voltage to be dramatically reduced. For this reason, as coauthor Masaki Tanemura from the Nagoya Institute of Technology explained, rugged surface structure is usually necessary for practical field electron emission sources, but so far ruggedness has not allowed for transparency.“Imagine sand-blasted glasses,” Tanemura told PhysOrg.com. “Glasses are transparent, but sand-blasted glasses are not due to the light scattering by the rugged surface structure. Similar to this example, transparency has not been possible for FEE sources.”By fabricating CNCSs that are smaller than the wavelength of visible light, the researchers found that they could overcome this challenge to produce fully transparent and flexible field electron emitters.“CNCSs have given transparency and flexibility to FEE sources for the first time,” Tanemura said. “To get CNCS-based transparent materials, it is highly desirable to control the diameter and length of the CNCSs. We have successfully controlled the diameter and length of the CNCSs below the wavelength of visible light at room temperature using an ion irradiation method. A careful scanning electron microscopy (SEM) inspection revealed that the diameter and length of most of the CNCSs were lower than the wavelength of the visible light. Thus this unique structure of the CNCSs was very useful to fabricate a CNCS-based transparent and flexible field electron emitter.” More information: Pradip Ghosh, M. Zamri Yusop, Syunsaku Satoh, Munisamy Subramanian, Akari Hayashi, Yasuhiko Hayashi, and Masaki Tanemura. “Transparent and Flexible Field Electron Emitters Based on the Conical Nanocarbon Structures.” J. Am. Chem. Soc. Doi:10.1021/ja909346e Explore furthercenter_img (PhysOrg.com) — During the past several years, researchers have used carbon nanotubes and nanofibers to fabricate a variety of transparent, flexible devices, such as OLEDs, transistors, and solar cells. But the development of transparent and flexible field electron emitters made of these nanomaterials still remains a challenge. In a new study, a team of researchers from Japan and Malaysia has shown that the key to the challenge may lie in the unique geometry of conical nanocarbon structures (CNCSs). In their experiments, the scientists bombarded a nafion substrate with argon ions for 30 seconds at room temperature. The irradiation produced uniformly distributed CNCSs over the entire nafion surface. The scientists measured that individual CNCSs had a base diameter of about 200 nanometers and a length/height of a few hundred nanometers, which is smaller than the wavelength of visible light. Overall, the material’s emission characteristics (its turn-on and threshold fields) were comparable to previous opaque electron emitters.As the researchers explain, the new method of using CNCSs for constructing transparent and flexible field electron emitters has several advantages. The method is simple in that it can be performed at room temperature, doesn’t require a catalyst, and doesn’t risk damaging the substrate. The scientists attribute these advantages to the unique conical geometry of the CNCSs. As a next step, the scientists plan to fabricate a transparent, flexible phosphor material, which is necessary for observing visible light emission and for the future construction of complete FEDs. The researchers predict that the technique could lead to transparent, flexible FEDs that are lightweight and inexpensive.“FED is a kind of flat panel display,” Tanemura explained. “Compared with other types of flat panel displays such as LCDs and electroluminescence displays, FED is advantageous in its brightness and size (a huge size is possible).” He added that transparent, flexible FEDs have great potential for applications including so-called head-up displays and highly intelligent information displays used in the coming ubiquitous world, when computers become thoroughly integrated into our everyday activities. “For example, head-up displays will be used on a curved front glass of vehicles (airplanes, trains, cars, and so on), full-face helmets, spectacles, and so on,” he said. “Usually it is transparent, but various kinds of information, such as maps, customer information, alarms, and security, will be displayed on demand. In the ubiquitous world, displays should be foldable (rollable) and light for mobility. You can enjoy TV, movies, games, communication, and obtain various kinds of information using an unfolded wide screen. Transparent and flexible FEDs make it realistic!” Citation: Conical nanocarbon structures could lead to flexible, transparent field emission displays (2010, March 25) retrieved 18 August 2019 from https://phys.org/news/2010-03-conical-nanocarbon-flexible-transparent-field.html This SEM image shows conical nanocarbon structures (CNCSs) fabricated on a transparent and flexible nafion substrate. Because the CNCSs are smaller than the wavelength of visible light, they have given transparency and flexibility to field electron emission sources for the first time.

Midair smoke forces IndiGo flight to make emergency landing in Kolkata

0 Comment

first_imgKolkata: A Jaipur-Kolkata IndiGo flight with 136 passengers on board made an emergency landing in Kolkata after smoke engulfed the plane mid-air, prompting the government to order a probe, an official said Tuesday. However, no passengers were injured in the incident that happened on Monday, a senior DGCA official said. The pilot had to issue a ‘May Day’ call, made to seek help in times of distress, and the the Pratt & Whitney-powered Airbus A320 Neo plane landed at the Kolkata airport under full emergency conditions, a source said. Also Read – Rain batters Kolkata, cripples normal life On landing, some of the passengers were evacuated using emergency chutes, the source said. “The IndiGo aircraft VT ITR was about 45 miles off Kolkata when the smoke engulfed the aircraft. Amid the passengers’ safety in danger, the pilot issued May Day and sought an emergency landing at the Kolkata airport,” the source said. IndiGo confirmed the incident but said the aircraft did not face any technical issue in the past. “An IndiGo flight (A320 aircraft) 6E-237 operating on Jaipur-Kolkata route made an emergency landing as a precaution at Kolkata due to suspected smoke in cabin,” the airline said in a statement. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killed There was no report earlier of any malfunctioning in the aircraft, it said. The flight landed safely at Kolkata, it said, adding that on reaching the bay, a few passengers were evacuated via the “aft exit deployed slides” while most passengers deplaned via the front step ladder. The Airbus A320 Neo planes with Pratt & Whitney engines, which are being operated by budget carriers IndiGo and GoAir, have been frequently facing serious glitches mid-air and on ground since their induction. The senior official of the Directorate General of Civil Aviation (DGCA) said the “flight made an emergency landing at Kolkata due to smoke in cockpit and cabin”. On landing, the aircraft was taken to an isolation bay, where aft or emergency passenger chutes were deployed and few passengers were evacuated, the official said. The Aircraft Accident Investigation Board (AAIB), which comes under the Civil Aviation Ministry, has launched a probe into the incident, he said. The airline has also been asked to submit a preliminary report after a detailed technical inspection, he added.last_img read more

Heres What Oculus Just Revealed at Its MuchAnticipated Press Event

0 Comment

first_img Rumors about the hotly anticipated virtual reality system Oculus Rift have been swirling for some time now, but many of the details remained shrouded in mystery.Earlier today – after a short initial delay – Oculus VR’s CEO Brendan Iribe took the stage to shed some light on the virtual reality system. Speaking to an audience in San Francisco, Iribe didn’t skimp on the drama. At long last, he said from his onstage perch, users will be able to “experience anything, anywhere. It is that powerful. For the first time we will finally be inside of the game. This is going to change everything…It is finally here.”Here’s what was covered at the press conference:A partnership with MicrosoftAfter dropping that each Oculus Rift will include an Xbox One controller and adapter, Iribe brought Phil Spencer, head of Xbox, onto the stage. “People will be able to stream their Xbox One games to the Oculus Rift using the controller that they know and love,” Spencer told the audience, before announcing that Oculus VR and Windows 10 have entered into a partnership.Release date and pricingUnfortunately, we don’t have a release date yet, although Iribe narrowed it down to sometime in Q1 2016. As to pricing, Iribe offered no further details (the company has previously suggested that the Oculus plus a VR-ready PC will cost $1,500). Games and experienceAs game developers, “there’s always this unfulfilled promise, a distance between players and the worlds we were making for them,” Jason Rubin, head of worldwide studios at Oculus, told the audience. “VR changes that. Finally, we can create worlds that feel real.”To illustrate the point, a procession of game studio execs took the stage, each showcasing a game built explicitly for virtual reality (in 2-D, but there’s no real way around that as of yet). They included: Hilmar Petursson of CCP who demoed EVE: Valkyrie; David Adams of Gunfire Games who demoed Kronos; and Ted Price of Insomnia Games who demoed Edge of Nowhere.Image Credit: oculus.comRelated: Game Over? Oculus Fans Outraged by Facebook PurchaseRubin then revealed a partial list of additional games coming to the VR platform in early 2016, including Damaged Core by High Voltage, VR Sports Challenge by Sanzaru Games, Esper by Coatsink, AirMech by Carbon Games and Lucky’s Tale by Playful Corp.DesignTo illustrate its lightness, Iribe brought the Oculus Rift headset on stage. “I can hold it with one hand,” he said, brandishing it about. Irbie went on to highlight additional design features such as the device’s custom display and optic system, which eliminates “motion blur, judder or pixels…it feels as if you just put on a pair of glasses,” and the strap architecture, designed to maximize comfort. “You’re going to put it on like a baseball cap,” he explained.  Hand and finger-tracking controllersThe biggest reveal, saved for the end of the conference and delivered by Oculus founder Palmer Luckey, was the unveiling of Oculus Touch (codenamed Half Moon), i.e. a pair of hand and  finger-tracking wireless controllers that allow users to manipulate objects, make hand gestures and experience “hand presence” within virtual reality. Luckey showed them off onstage, although he labeled them “a prototype.”“This isn’t science fiction,” Luckey told the audience. “This is reality, and it’s happening today.”Image Credit: oculus.comRelated: Will Tomorrow’s Entrepreneurs Learn With Virtual Reality? 4 min read June 11, 2015 Free Webinar | Sept 5: Tips and Tools for Making Progress Toward Important Goals Opinions expressed by Entrepreneur contributors are their own.
