Before reaching the electrode’s surface, the ions have to travel through narrow nanopores as quickly and efficiently as possible. Basically, the quicker the ions can travel down these paths, the quicker the capacitor can be charged, resulting in a high rate performance. Also, the greater the adsorbed ion density in the electrode, the greater the charge that the capacitor can store, resulting in a high volumetric capacitance.Recently, scientists have been testing materials with pores of various sizes and structures to try to achieve both quick ion transport and high adsorption ion density. But the two requirements are somewhat contradictory, since ions can travel more quickly through larger nanopores, but large nanopores make the electrode density low and thus decrease the adsorbed ion density.“In this work, we have successfully demonstrated that it is possible to meet the two seemingly contradictory requirements, high power density and high volumetric capacitance, with zeolite-templated carbon,” Nishihara told PhysOrg.com.The zeolite-templated carbon consists of nanopores that are 1.2 nm in diameter (smaller than most electrode materials) and that have a very ordered structure (whereas other pores can be disordered and random). The nanopores’ small size makes the adsorbed ion density high, while the ordered structure – described as a diamond-like framework – allows the ions to quickly pass through the nanopores. In a previous study, the researchers showed that zeolite-templated carbon with nanopores smaller than 1.2 nm cannot enable fast ion transport, suggesting that this size may provide the optimal balance between high rate performance and high volumetric capacitance.In tests, the zeolite-templated carbon’s properties exceeded those of other materials, demonstrating its potential to be used as an electrode for high-performance electric double-layer capacitors.“We are now trying to further increase the energy density of the zeolite-templated carbon up to the same level of secondary batteries,” Nishihara said. “If such an electric double layer capacitor is developed and used for mobile devices, such as cellular phones, their charging time can be shortened to only a few minutes. Another important future application of electric double layer capacitors is a support of secondary batteries in electric vehicles to prolong the battery’s lifetime. Also for this purpose, achieving a higher energy density is one of the key issues.” (PhysOrg.com) — In order to develop next-generation electric vehicles, solar energy systems, and other clean energy technologies, researchers need an efficient way to store the energy. One of the key energy storage devices for these applications and others is a supercapacitor, also called an electric double-layer capacitor. In a recent study, scientists have investigated the possibility of using a material called zeolite-templated carbon for the electrode in this type of capacitor, and found that the material’s unique pore structure greatly improves the capacitor’s overall performance. The unique 3D array of nanopores in zeolite-templated carbon enables it to be used as an electrode for high-performance supercapacitors that have a high capacitance and quick charge time.

Eos says zinc battery recipe is energy gamechanger

first_img 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. © 2011 PhysOrg.com New rechargeable zinc-air batteries coming soon (PhysOrg.com) — Tall order in energy storage: Find the right technology that delivers the holy grail of the grid, a viable solution for energy storage (tough). A startup from Easton, Pennsylvania claims it’s on the fastest path. Eos Energy Storage has a formula for zinc-air batteries that it thinks can eventually be the dominant technology for use in the grid. Eos Energy is on a mission to develop a low-cost, high-energy rechargeable zinc-air battery for utility and transportation applications.Zinc air technology in general has been recognized as an environmentally safe approach with the benefit of high energy densities. What has held the technology back has been low efficiency and short life cycles. Though cheaper, though lighter, than lithium ion batteries, zinc air batteries have run down much more quickly, unsuitable for application on a grid level. The batteries have so far been largely limited to the small button cells used for hearing aids. Eos Energy says it resolved the shortcomings through its advances in electrolyte chemistry and cell design. Its proprietary technology involves the battery architecture, electrolyte composition and management and manufacturing process. Eos zinc air technology has been under development by Eos since 2004.CEO Michael Oster, has said that this is “not your typical zinc-air.” Steven Amendola, an inventor and founder of Eos, is also the founder of Renewable Silicon International (RSi), a silicon processing technology.The company says its batteries beat out lithium ion batteries in energy storage and cost. Their trials show over 2,700 cycles with no performance physical degradation in a one third kilowatt-scale battery. Their goal is to get over 10,000 cycles at full depth of discharge. Their final product is expected to last for 30 years in grid-scale applications.Analysts say that the company’s technology could show promise for grid storage and electric vehicles. With the right pricing and performance, zinc air batteries may compete not only against other energy storage systems but also grid technologies such as gas turbine plants. The company has an impressive list of product benefits, and investors have been responsive. Eos zinc-air battery is environmentally safe, in that it relies on materials that are nontoxic and nonflammable. Oster has said, “You could flush it down a drain; you could drink it.” In an SEC filing, Eos indicated its plans to raise up to $20 million in venture capital.Eos plans to start manufacturing this year and to work up megawatt-scale systems for grid storage in 2013. The Eos rechargeable zinc-air battery would be sold for $1000 per kilowatt for a six-hour battery, or $160 per kilowatt-hour. Zinc generally enjoys status as one of the world’s most plentiful and inexpensive metals, along with its other qualities as being stable, nontoxic and energy-dense.

FBI steps up to 1B nextgen ID program

first_img The new undertaking will also store latent and rolled fingerprints and palm prints. The FBI has been pilot testing a facial recognition system where agents will seek to match up existing mugshots with faces in crowd photos; and in the reverse they will compare images of interest from security cameras with the repository of shots in their database. An algorithm would perform an automatic search and return a list of potential hits for an officer to sort through and use as possible leads for an investigation. Another advancement on the books is the ability to accept and search for photographs of scars, marks, and tattoos.According to the FBI’s Jerome Pender, in February 2012, the state of Michigan successfully completed an end-to-end Facial Recognition Pilot transaction and is submitting facial recognition searches to the CJIS (Criminal Justice Information Services Division). Pender said that MOUs (Memorandums of Understanding) have been executed with Hawaii and Maryland, and South Carolina, Ohio, and New Mexico are engaged in the MOU review process for Facial Recognition Pilot participation. Kansas, Arizona, Tennessee, Nebraska, and Missouri, he said, are also interested in Facial Recognition Pilot participation. Pender was making the statement before the Senate Judiciary Committee, Subcommittee on Privacy, Technology, and the Law, in Washington in July. Pender is presently executive assistant director of the FBI’s Information and Technology Branch.The facial recognition database is scheduled for rollout nationwide by 2014. A report about the FBI’s initiative in New Scientist notes that facial recognition technology is improving all the time. Tests in 2010 already showed that the best algorithms can choose someone in a pool of 1.6 million mugshots 92 per cent of the time. The report added that algorithms developed at Carnegie Mellon can analyze features of a front and side view set of mugshots, create a 3-D model of the face, rotate it as much as 70 degrees to match the angle of the face in the photo, and match the new 2-D image with a fairly high degree of accuracy.Also touting the powers of facial recognition technology, Alessandro Acquisti of Carnegie Mellon has noted that under certain conditions, machine face recognition performance can be comparable or even better than humans at recognizing face.Predictably, privacy advocates are worried about how far the FBI will go in deployment. They are concerned about legal implications of law enforcement use of facial recognition technology. The FBI has assured that the searchable photo database in the pilot studies only includes mugshots of known criminals and that each participating pilot state or agency must submit written statements detailing how they will use and protect the information from unauthorized disclosure.In reaction to the FBI’s Jerome Pender’s statements to the Senate in July that the searchable photo database used in the pilot studies only includes mugshots of known criminals, attorney Jennifer Lynch of the Electronic Frontier Foundation said it was unclear from the NGI’s privacy statement whether that will remain the case once the entire system is up and running or if civilian photos might be added. (Phys.org)—The good news is that the FBI is crawling out of the fingerprint age. They are moving up into a $1 billion project that will enable criminal searches and accurate identifications using updated technologies including a range of biometrics. The bad news, at least for privacy advocates, is one and the same. Privacy groups are asking, biometrics, at what price? How will they be used and who is to guarantee against their abuse? Nonetheless, the FBI is set to witness significant improvements to their existing fingerprint identification services, and there is an ambitious title behind their resolve, the $1 billion Next Generation Identification (NGI) program. Eventually this program is to encompass facial recognition, iris scans, DNA analysis and voice identification. Explore further © 2012 Phys.org This document is subject to copyright.

Faint polarized flares detected from the variable star UV Ceti

first_img(Phys.org)—Astronomers have detected four faint, polarized flares at 154 MHz from the nearby variable star UV Ceti. The newly observed flares are much fainter than most flares found at these frequencies. The findings were presented February 10 in a paper published online on the arXiv pre-print server. Faraday dispersion function of UV Ceti at 154 MHz during the off and on period of the Dec. 11, 2015 flare. Credit: Lynch et al., 2017. Located just about 8.7 light years away, UV Ceti, or Luyten 726-8B, belongs to a nearby binary star system Luyten 726-8. It is a variable red dwarf of spectral type M, just like its companion star BL Ceti (Luyten 726-8A). Due to its proximity, this star system is a treasure trove for astronomers studying flaring events of magnetically active stellar systems.That is why a team of researchers led by Christene Lynch of the University of Sydney in Australia selected UV Ceti as a target of radio astronomy observations in December 2015. They used the Murchison Widefield Array (MWA) in Australia to confirm previous bright flare detections in the system at 100 to 200 MHz. The array allowed the scientist to get a glimpse of low-level flares fainter than expected.”We have detected four flares from UV Ceti at 154 MHz using the Murchison Widefield Array,” the paper reads.The observation sessions, which used a 30.72 MHz bandwidth centered at 154 MHz with 40 kHz channels and 0.5-second integrations, allowed the team to observe flare emission in the polarized images. In each epoch, they detected a single right-handed circularly polarized flare, finding also a left-handed flare immediately following the right-handed one. Moreover, they detected linear polarization during the brightest flare, what indicates that the flares are elliptically polarized. The researchers noted that these results highlight the importance of polarization images in such studies.”These dim flares are only detected in polarized images, which have an order of magnitude better sensitivity than the total intensity images. This highlights the utility of using polarization images to detect low level emission in confusion limited images,” the team wrote in the paper.The study also revealed that the newly detected flares have flux densities between 10 to 65 mJy. This means that they are about 100 times fainter than most flares observed so far at similar frequencies. Notably, three of the four flares described in the paper have flux densities below 15 mJy, while the one observed on Dec. 11, 2015 reached nearly 65 mJy.The researchers emphasize that their study provides first flare rate measurements for low-intensity (below 100 mJy) flares at 100 to 200 MHz. However, they note that there is still much to accomplish in the field of flare emission research and recommend further observations. Future studies would improve our understanding of physical parameters of the stellar magnetospheric plasma.”To better characterize M dwarf flares at meter wavelengths requires more observational time on individual sources to constrain flare rates. More sensitive observations are also needed to investigate the fine time-frequency structure of the flares. Simultaneous multi-wavelength observations would also add to this analysis,” the team concluded. This document is subject to copyright.

More information: 154 MHz detection of faint, polarized flares from UV Ceti, arXiv:1702.03030 [astro-ph.SR] arxiv.org/abs/1702.03030AbstractWe have detected four flares from UV Ceti at 154 MHz using the Murchison Widefield Array. The flares have flux densities between 10—65 mJy —- a factor of 100 fainter than most flares in the literature at these frequencies —- and are only detected in polarization. The circular polarized fractions are limited to >27% at 3σ confidence and two of the flares exhibit polarity reversal. We suggest that these flares occur periodically on a time scale consistent with the rotational period of UV Ceti. During the brightest observed flare, we also detect significant linear polarization with polarization fraction >18%. Averaging the data in 6-minute, 10 MHz frequency bins we find that the flux density of these flares does not vary over the 30 MHz bandwidth of the Murchison Widefield Array, however we cannot rule out finer time-frequency structure. Using the measured flux densities for the flares, we estimate brightness temperatures between (1013−1014)K, indicative of a coherent emission mechanism. The brightness temperature and polarization characteristics point to the electron cyclotron maser mechanism. We also calculate the flare rates given our four observed flares and compare them to flare rates for the set of M dwarf stars with known 100—200 MHz flares. Our measurement is the first for flares with intensities <100 mJy at 100-200 MHz.

Topological negative refraction of surface acoustic waves in a Weyl phononic crystal, Nature (2018). DOI: 10.1038/s41586-018-0367-9AbstractReflection and refraction of waves occur at the interface between two different media. These two fundamental interfacial wave phenomena form the basis of fabricating various wave components, such as optical lenses. Classical refraction—now referred to as positive refraction—causes the transmitted wave to appear on the opposite side of the interface normal compared to the incident wave. By contrast, negative refraction results in the transmitted wave emerging on the same side of the interface normal. It has been observed in artificial materials, following its theoretical prediction6, and has stimulated many applications including super-resolution imaging7. In general, reflection is inevitable during the refraction process, but this is often undesirable in designing wave functional devices. Here we report negative refraction of topological surface waves hosted by a Weyl phononic crystal—an acoustic analogue of the recently discovered Weyl semimetals. The interfaces at which this topological negative refraction occurs are one-dimensional edges separating different facets of the crystal. By tailoring the surface terminations of the Weyl phononic crystal, constant-frequency contours of surface acoustic waves can be designed to produce negative refraction at certain interfaces, while positive refraction is realized at different interfaces within the same sample. In contrast to the more familiar behaviour of waves at interfaces, unwanted reflection can be prevented in our crystal, owing to the open nature of the constant-frequency contours, which is a hallmark of the topologically protected  surface states in Weyl crystals. As most kids learn in school, when light rays strike a body of water, some are bent by the water, while others are reflected. Baile notes that in such situations, the incident and refracted rays wind up on opposite sides of the surface of the water—which opticians describe as the norm. He also notes that this is what happens with virtually all materials in nature. But he also notes that theory suggests that it should be possible to create materials that violate the norm. In this new effort, the researchers have created just such a material.The researchers report that they made the new material by first studying the properties of a Weyl semimetal—a recently discovered quantum material that has interesting topological properties. To apply what they learned to a non-metal material, they created trilayer plates of phononic crystals using epoxy and other materials (shaped in a specific way). They then stacked the plates in twisted counterclockwise fashion by 2π/3 along the vertical axis. In so doing, they found that the resultant material not only exhibited negative refraction, but also absorbed all of the acoustic waves aimed at it, reflecting none.Baile suggests that the material could lay the groundwork for new developments in many areas—if a similar material can be created to behave the same way with optical waves, for example, that could lead to new types of optical systems. He notes that such a material could likely find many uses in acoustical systems as well, such as improved ultrasonic devices. He further notes that reflection-free materials could improve the efficiency of many current devices. A team of researchers with members from Wuhan University and the University of Texas has created an artificial material that offers both negative refraction and no reflection. In their paper published in the journal Nature, the group describes their material, how it was made, and possible uses for it. Baile Zhang with Nanyang Technological University offers a News & Views piece on the work done by the team in the same journal issue.last_img read more

Fatherson duo among three held for over Rs 150 cr gold diversion

first_imgKolkata: Three men, including a father-son duo, have been arrested by the DRI for allegedly diverting gold jewellery worth at least Rs 150 crore meant for foreign markets to use in India, according to an official statement issued today. The Directorate of Revenue Intelligence (DRI) is investigating gold jewellery exporters declaring exports using the personal hand carry export procedure’ a government policy that allows exporters to carry gold jewellery in hand baggage instead of cargo to destinations in United Arab Emirates (UAE) but diverting the consignments into the domestic market by manipulating the procedure. Also Read – Heavy rain hits traffic, flightsThe accused were arrested from the international airport here when they were trying to divert Rs 15 crore worth gold jewellery, it said.While the son was intercepted at the time of boarding a flight to Dubai, his father was de-boarded from a flight destined to Hyderabad, the statement said.Documents were filed by them at the Customs Air Cargo Complex, Kolkata, for export by hand carriage of gold bangles weighing 54 kg to be carried to Dubai by the son on board the flight bound for Dubai. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedAfter the gold bangles were checked by the customs at the cargo, as per procedure, the items were sealed and escorted to the airport.”Before entering immigration and security check, the son took the goods meant for export to an entry gate of the airport where his father was waiting and handed them over for diversion. The father then booked the two metal boxes containing the gold bangles through domestic cargo for transfer to Hyderabad,” it said.DRI officials acted in the nick of time and intercepted the two as they were about to board/ had boarded their respective flights and also retrieved two metal boxes containing the gold booked for Hyderabad as domestic cargo. Surprisingly, the father was found to be travelling to Hyderabad from Kolkata on a ticket in the name of his son, the DRI said.In the latest case, the diverted gold bangles weighing 54 kg and valued at about Rs 16 crore meant for export have been seized by the DRI.”DRI investigations till now reveal that more than 500 kg of gold jewellery, valued at about Rs 150 crore, meant for export has been diverted using this modus operandi by this particular syndicate,” the statement said.The agency is investigating whether this modus operandi has been used by other gold jewellery exporters in the country, it said.Both accused admitted to have diverted gold bangles/chains in similar fashion in the past through Kolkata as well as Hyderabad airports after completion of the customs export procedure.Another associate of these two accused was examined by the DRI and he also admitted that he was involved and diverted gold jewellery meant for export through airports after completion of the export procedure.The mastermind confessed to have received remittances against such export consignments though no actual gold bangles were physically exported, the probe agency said.He used to send cash to his Dubai-based contacts through hawala channels and got the money back into his Indian bank accounts as export proceeds, it said.He admittedly sold primary gold purchased from nominated agencies in the domestic market instead of making gold jewellery for export.For fulfilment of their export obligation and to redeem the security amount paid by them to nominated agencies at the time of purchase of primary gold, they had resorted to diversion of gold bangles meant for export after completing all export formalities, the DRI said.In fact the same sets of gold bangles were repeatedly used to show export of different consignments, it said.Three people have been arrested in this case.last_img read more

Talks before accusations

first_imgIt was a day of much activity on the India-Pakistan border. On Wednesday, a suspected Pakistani terrorist was caught alive after militants attacked a Border Security Force (BSF) convoy on Jammu-Srinagar national highway in Udhampur killing two men of the border guarding force and injuring 11 personnel. The other terrorists involved in the strike were shot dead in the retaliatory fire. The terrorist identified as Usman Khan, and then later identified him as Mohammad Naved, had escaped from the encounter site and taken three persons hostage in a school building in a nearby hamlet.  Also Read – ‘Playing Jojo was emotionally exhausting’However, with the aid of local villagers, the Indian security forces soon arrested Naved. Interrogation by the Jammu and Kashmir police later in the day had reportedly revealed that Naved is a resident of Faisalabad in Pakistan. Obvious comparisons are being drawn with Ajmal Kasab, the only Pakistani terrorist captured alive after the 26/11 terror attack on Mumbai. Giving further credence to such an assessment, Naved has reportedly told interrogators that he is a member of the Lashkar-e-Taiba, the same terror group involved in the Mumbai attacks.  Also Read – Leslie doing new comedy special with NetflixThe attack comes at a time of much churning on the geopolitical front between India and Pakistan. Both sides are slated to hold National Security Advisor (NSA)-level talks later this month, with terrorism on top of the agenda.  For a long time, both sides have accused one another of harbouring and facilitating terror attacks on their side of the border. The Indian side believes that certain sections of the military and intelligence establishment in Pakistan have harboured, financed and facilitated the flow of terrorism on the Indian side of the border, especially in Jammu and Kashmir.  In recent times, the 26/11 Mumbai attacks and events in Gurdaspur, have been used as examples of the Pakistan’s reported culpability.  Meanwhile, the Pakistani establishment has long blamed India for facilitating terror activities in the country, especially in the civil strife-torn region of Baluchistan. With terrorism on the agenda for the NSA-level talks, these accusations are bound to come to the fore. However, before both sides get mired in cross-border accusations instead of fruitful talks, they should listen to the wise words of Tariq Khosa, the former head of Pakistan’s Federal Investigation Agency (FIA), who supervised the investigation behind the 26/11 Mumbai attacks. In his column for a leading Pakistani daily, Khosa said that investigators had uncovered a mountain of evidence linking the Lashkar-e-Taiba (LeT) to the carnage that was “planned and launched” from Pakistani soil. Khosa goes on to write that authorities in Pakistan must bring the perpetrators and masterminds of the “ghastly terror attacks” to justice. According to Khosa, the slow pace of court proceedings that are looking into the 26/11 attacks can be attributed to the deliberate sabotage of the legal process. The Pakistani state apparatus, according to Khosa, has to deal with the fallout of the attacks and this will require “facing the truth and admitting mistakes”. LeT Commander Zakiur Rehman Lakhvi and six others, were arrested in Pakistan and charged with planning, financing and facilitating the attacks. Their trial, however, has dragged on since 2009, with Lakhvi released on bail in April, 2015. Despite a sense of redemption for Indian authorities, there is a key lesson that both sides must take into account before they sit for talks. As Khosa writes, “They (India) too have many skeletons in their cupboards. So why fight shy? Let both India and Pakistan admit their mistakes and follies and learn to coexist while trying to find solutions to their thorny issues through peaceful means”. As figures on the international forum, it is imperative that they do not get cowed down by the forces of domestic politics. It is, of course, easier said than done. For lasting peace, however, certain sacrifices must be made, with astute diplomacy leading the way.last_img read more

Understanding pulse of our times

first_imgThe fifth edition of India Habitat Centre’s Indian Languages Festival “ILF Samanvay 2015” got off to a phenomenal start. This year’s theme of ILF Samanvay is ‘Insider/Outsider, Writing India’s Dreams and Realities’. This year, the festival broadened its mandate by developing in a range of verticals such as a curated art space, daily workshops by eminent experts in a range of topics from translation to food appreciation, book releases, social outreach in schools with the festival resource persons, and curated food stalls focusing on the food traditions of Kashmir, Bengal, Tamil Nadu and Maharashtra.

Hence, the study of Indian literature should be historically grounded and organised primarily in terms of particular linguistic traditions and regional clusters, and discussed on the model of what I would call ‘regional Indian cosmopolitanism’. The points of intersection of different linguistic-literary traditions, along with causes and consequences of those overlaps, should be established through careful investigation. The hierarchical relations of power that exist among languages and traditions must be examined, and a system of education that profoundly addresses the question of multilinguality, developed. Such a system must also give room to understand the widespread connection between the linguistic-literary and the performative.” This component articulates and interprets language as a flow beyond the literary in our unsettling times. The art works of Riyas Komu, co-founder of the Cochin-Muziris Biennale, artist-weaver Priya Ravish Mehra, and performance photography exhibition curated by Kanika Anand are among the highlights.
