Pilot models of the Uber self-driving car are displayed at the Uber Advanced Technologies Center in Pittsburgh, Pennsylvania. AFP file photoRide-sharing giant Uber said Monday it is suspending use of self-driving cars after one of the vehicles struck and killed a pedestrian in the US state of Arizona.The Uber vehicle was in autonomous mode, with an operator behind the wheel, when it hit a woman walking in the street in the city of Tempe late Sunday, according to the San Francisco-based company.The victim was hospitalized and later died from her injuries.“Our hearts go out to the victim’s family,” an Uber spokesperson told AFP. “We are fully cooperating with local authorities in their investigation of this incident.”Uber said it had temporarily halted its use of self-driving cars for testing or customer rides in Tempe, Pittsburgh, Toronto, and San Francisco.Tempe is one of just two cities—along with Pittsburgh—where the ride-sharing firm has been using autonomous vehicles as part of its regular passenger.The vehicle operator in the driver’s seat was the only person in the car when the accident occurred, Uber said. The car was in police hands on Monday.Sunday’s accident was the first fatal self-driving car crash involving a pedestrian.The first deadly self-driving car accident was reported in mid-2016, and involved a Tesla.Sheriff needed?The Tesla Model S, cruising on “Autopilot,” failed to detect a crossing tractor-trailer against a bright sky, killing the driver—who it later emerged had kept his hands off the wheel for extended periods of time despite automated warnings not to do so.Investigators at the US National Transportation Safety Board determined the probable cause of the Tesla crash was the combination of “a truck driver’s failure to yield the right of way and a car driver’s inattention due to overreliance on vehicle automation.”Autonomous-vehicle technology has been touted as having potential to save fuel, ease congestion, and to save thousands of lives by avoiding accidents due to human error.As with the fatal Tesla crash, however, the deadly Uber accident is likely to stoke concerns that the industry is moving too fast.Google-owned Waymo this month began using its self-driving trucks to haul cargo bound for the internet giant’s data centers in Georgia, while rival Uber announced the use of self-driving semi trucks as part of an on-demand trucking service in Arizona.In September, US Transportation Secretary Elaine Chao released new guidelines that permit more testing of self-driving cars.But America’s non-profit Consumer Watchdog has warned that roads are being turned “into private laboratories for robot cars with no regard for our safety.”The group on Monday called for a nationwide moratorium on testing self-driving cars on public roads while investigators figure out what went wrong in the Uber accident.“Arizona has been the wild west of robot car testing with virtually no regulations in place,” Watchdog technology project director John Simpson said in a statement.“When there’s no sheriff in town, people get killed.”Car vision tests?US states set their own rules for roads, and a handful have passed laws allowing self-driving vehicles.California and Arizona have been particularly encouraging, hoping that companies developing autonomous technology in those states will create local jobs and facilities devoted to a promising new industry.Duke University robotics professor Missy Cummings is among the advocates of slowing down introduction of autonomous vehicles to avoid risk and get proper regulations in place.While machines are better at staying vigilant and reacting to routine situations, human drivers have proven superior at handling unusual or unexpected situations, according to the professor.Cummings reasoned that if people need to pass vision exams in order to get driving licenses, so should self-driving cars.She noted a case in which putting stickers on a stop sign could fool autonomous car sensors into seeing it as a sign indicating a speed limit.“If we are still learning at this rate, and still uncovering major problems, it begs the question of why we are trying to put this technology into widespread use,” Cummings told AFP.“I am a big fan of the technology, but it is very unproven and experimental.”
The high-profile deaths of unarmed Blacks have put the law enforcement profession on the defensive. Their leaders recently responded with a forum explaining their practices and procedures.On Oct. 12, the Office of The U.S. Attorney of the District of Columbia sponsored a forum, “Police and Community: Building a Bridge of Trust” that took place at the Shiloh Baptist Church in Northwest D.C. The purpose of the forum was to allow law enforcement leaders to explain their duties and responsibilities to advisory neighborhood commissioners, civic association officers, and community activists.Morgan C. Kaine is the First District commander for the D.C. police department. (AFRO File Photo)“We are out there every day,” said Morgan C. Kaine, commander of the D.C. Metropolitan Police Department’s First District. “Many police officers spend hours in the community on their own time. We sponsor events like ‘Shop with a Cop’ and activities like that.”Kaine said that District residents can get involved in police activities through its junior cadet program for teenagers and the Community Engagement Academy that teaches people what police officers deal with. She encouraged members of the audience to ride along with an officer. “You get to see what police officers have to go through every day,” she said.Kaine said people should remember one critical thing as they observe police officers doing their jobs. “We are human. Our goal is to keep you safe,” she said.Unlike other municipalities, the District has several police agencies operating within its borders because of the city’s federal presence. Lt. James Murphy works for the U.S. Park Service Police Department that is responsible for all national parks in the D.C., New York, and San Francisco metropolitan areas.Murphy said that many residents and visitors don’t understand the jurisdictional lines between the D.C. police department and his agency. “For example, we patrol Lafayette Park across from the White House but when you step outside of it, in front of the White House, you are in D.C. police jurisdiction,” Murphy said. “If you misbehave on national parks lands, we have the same arrest powers as the D.C. police.”Assistant U.S. Attorney Jonathan Malis explained what his office entails and whom they work with and report to. The District of Columbia doesn’t have a local prosecutor therefore the U.S. Attorneys’ Office serves in that capacity. “My boss, Channing Phillips, reports to U.S. Attorney General Loretta Lynch,” Malis said, inferring that he doesn’t answer to D.C. Mayor Muriel Bowser (D). “Keep in mind that we don’t report to MPD but we work with them on cases.”When it comes to an officer accused of wrongdoing, Malis said the case is prosecuted as fairly and independently as any other case. “That independence is important,” he said.Malis said prosecuting an officer for killing a resident consists of getting an autopsy and gathering evidence to determine whether that officer should be charged on the “reasonable officer” standard. “We look at the facts and determine whether the police officer acted reasonably during the course of action,” he said. “That is a standard set up by the U.S. Supreme Court and we abide by it.”Even though the forum occurred after a recent officer involved-shooting of an unarmed man, Terrence Sterling, in the District, William Miller, a spokesman for the U.S. Attorney’s office told the AFRO that the shooting did not spark the need for police to explain their tactics.Many people want to file a complaint against an officer but are afraid to because they think it is difficult and there will be retaliation by the police department. “Not so,” says Mike Tobin, the executive director of the District’s Office of Police Complaints.“You can file a complaint with an officer by going to the station, going online or mobile phone, going to our web site or by fax, asking an officer for a form and there are also community groups who can help someone start the complaint process,” Tobin said. “When we get that complaint, we do a thorough investigation and through that we have access to all police reports and camera material. If there is a problem with an officer or his behavior, we recommend mediation.”According to an annual report from the District of Columbia Office of Police Complaints, there were 407 complaints against D.C. police officers in 2015. Of the number, 71.6 percent of the complainants were from Black residents and 20.6 percent were from White residents. The report states that more Black officers received complaints, totaling 51.3 percent, while White officers only received 37.3 percent.
© 2016 Phys.org Citation: Plant cellulose prevents short circuits in batteries (2016, July 22) retrieved 18 August 2019 from https://phys.org/news/2016-07-cellulose-short-circuits-batteries.html In a new study published in Nano Letters, researchers from the Ulsan National Institute of Science and Technology (UNIST) in South Korea have designed a cellulose nanomat, or “c-mat,” separator membrane that contains a thin layer of nanoporous plant cellulose on top of a thick macroporous polymer layer. By finely tuning the thicknesses of the two layers, the researchers were able to design a separator membrane that delicately balances the tradeoff between preventing leakage current and supporting fast ion transport. With its tiny pores, the nanoporous cellulose layer prevents leakage current between electrodes, preventing short circuits. On the other hand, the macroporous polymer layer’s porous channels are too large to prevent leakage current between electrodes, but their large size enables them to function like “ionic highways” to rapidly transport charges.The new separator has another major advantage: At high temperatures (60 °C), batteries with the new separator membranes have an 80% capacity retention after 100 cycles, whereas batteries with typical commercial polymer separators maintain just 5% of their initial capacity after 100 cycles at the same temperature.The researchers explain that the large capacity loss in the commercial batteries at high temperature occurs due to unwanted side reactions between lithium salts and water, which produces harmful byproducts such as manganese ions. The nanoporous cellulose-based layer of the new separator membranes has a manganese-chelating ability, so that it binds to the manganese ions and prevents them from participating in the reactions that cause capacity loss. In addition, the macroporous polymer layer captures the acidic reactants that produce the manganese ions, resulting in fewer of these ions in the first place.”We demonstrate in this work that the chemically active cellulose-based c-mat separator can mitigate the manganese ion-induced adverse effects,” coauthor Sang-Young Lee, Professor at UNIST’s School of Energy and Chemical Engineering, told Phys.org. “This enables a remarkable improvement in the high-temperature cycling performance far beyond that which is attainable with conventional membrane technologies.”In the future, the researchers plan to modify the separators for potential use in next-generation rechargeable batteries such as sodium-ion, lithium-sulfur, and metal-ion batteries. “The c-mat separator is expected to be used for next-generation high-performance batteries with high temperature stability—for example, in large-sized batteries for electric vehicles and grid-scale electricity storage systems,” Lee said. In addition to its use as a battery separator membrane, the c-mat separator also has potential applications in membranes for desalination systems, as well as for ecofriendly sensors for heavy metal ions.

Credit: Kim et al. ©2016 American Chemical Society Explore further (Phys.org)—In order to prevent short circuits in batteries, porous separator membranes are often placed between a battery’s electrodes. There is typically a tradeoff involved, since these separators must simultaneously prevent leakage current between electrodes while allowing ions to pass through the porous channels to generate current. Conventionally, these membranes are made of synthetic materials, such as polymers.
