Touch Football Australia (TFA) National Representative Teams and squads were involved in a series of camps and events around the Country on the weekend that led to widespread media coverage and massive promotional exposure for the code on a National scale.TFA fielded an Australian Women’s Invitational Team in the Harvey Norman Beach Footy Series at Sydney’s Maroubra beach on the 16-17 December 2006.The event featured six elite teams battling it out for $100,000 in prize money for their choosen charity.Four of the teams – The Blues, the Maroons, the Pacific Islanders, and the Young Guns comprised wall to wall National Rugby League superstars, whilst the Australian Women’s Invitational Beach Footy team, and a Celebrity Team headlined by Andrew Johns, and Anthony Mundine completed the stellar field.The event received massive media exposure in print, radio, and television mediums through broadcast partners Channel Nine, News Limited, and Nova FM, and the Women’s Beach Footy Team were featured prominantly.Among the media exposure TFA received was the front page story of a four page Beach Footy liftout in Sydney’s Daily Telegraph on Friday, live radio interviews with Women’s players and updates on Nova FM, and 2UE, exposure on several National network news bulletins, and Channel Ten’s Sports Tonight.Channel Nine taped the Beach Footy Series and it will be aired in late February/ early March in the lead-up to the NRL season kick-off.The Australian Men’s Open Team travelled to Rockhampton for their final training camp of their 2007 World Cup campaign and enjoyed saturation exposure from the local media.The Touch Football loving town rolled out the red carpet for Tony Trad’s men and the 3 game series against a Central Queensland combination that featured Rugby League superstar Benji Marshall turning out as an Invitational player for Central Queensland in the last game, received daily print and television coverage in the region.To cap off an exciting time promotionally for the sport, the Australian Open Women’s Team were featured on Channel Ten’s Sports Tonight program Sunday evening in an excellent piece on their record as arguably Australia’s most successful National Women’s sporting Team.The Aussie girls have won 45 World Cup games straight in a 19 year unblemished run in World Cup competition.A further piece on the Australian Men’s Open Team will be featured on Sports Tonight before all seven teams depart Australia’s shores bound for Stellenbosch, South Africa on January 13 2007.There will be media stories circulating in the lead-up to the World Cup on Australian representative players and Teams so keep your eyes peeled for World Cup stories around the nation in coming weeks.
Wolves set for Abraham deal – but Chelsea won’t consider immediate saleby Paul Vegas10 months agoSend to a friendShare the loveWolves are confident of closing a deal for Tammy Abraham – however Chelsea insist they do not want to lose the striker permanently.The Daily Mail says Abraham, currently on-loan at Aston Villa, is keen to play in the Premier League and Wolves want competition for Raul Jimenez. Chelsea, who have until January 14 to trigger his recall, are reluctant to agree to a sale now despite Wolves intimating they would be willing to offer around £18m.The Stamford Bridge club will wait to see how he performs.They are aware and know that his value could increase significantly by the summer if he does well.

INDIANAPOLIS, IN – MARCH 10: Herky the hawk, mascot for the Iowa Hawkeyes performs against the Michigan State Spartans during the first round of the 2011 Big Ten Men’s Basketball Tournament at Conseco Fieldhouse on March 10, 2011 in Indianapolis, Indiana. Michigan State won 66-61. (Photo by Chris Chambers/Getty Images)Something needs to be done about Adam Woodbury, Big Ten. During the first half of Iowa’s game against Maryland Sunday afternoon, the Hawkeyes’ big man poked Terrapins’ freshman guard Melo Trimble in the eye. Trimble collapsed to the floor and had to leave the game for several minutes as his eye swelled up. No foul was called during the action, but the referees charged Woodbury with a Flagrant 1 after looking at the replay. It’s possible this specific incident was not an intentional play from Woodbury, but that seems unlikely since the 7-footer has done this before. During Iowa’s game against Wisconsin, he did it twice. This is happening far too many times for it to be unintentional. Some type of punishment – a suspension, perhaps – needs to be given to Woodbury from Big Ten commissioner Jim Delany.
This past Sunday night, Louisville took down Northern Iowa to reach its fourth straight Sweet 16. Senior Wayne Blackshear also became the first Cardinals player in school history to play for four straight squads that reached the second weekend of the NCAA Tournament. Tuesday morning, the school attempted to celebrate the accomplishment by posting the statistic to its Facebook page. Unfortunately, they screwed up and named Blackshear as the only player in NCAA Division One history to accomplish the feat. That isn’t even close to true, as dozens of players in college basketball history to have reached the Sweet 16 four straight times.Kentucky fans, predictably, are having a field day, claiming that the school is perpetuating a “lie.”…. “And the lie detector test determined….THAT was a lie!” @KySportsRadio pic.twitter.com/D1uwIpmGoJ— Jeremy Kemble (@IAM4UKWILDCATS) March 24, 2015UL Athletics sends out a blatant lie today http://t.co/ZTni2u97L9— Matt Jones (@KySportsRadio) March 24, 2015University of Louisville claims Wayne Blackshear is the first to appear in four Sweet 16 games. Kentucky has had seven players do that.— UK Cat Facts (@UK_CatFacts) March 24, 2015Regardless, Blackshear’s feat is quite impressive. Can we get a Kentucky vs. Louisville national championship game please?

Marc-Andre ter Stegen has voiced his opinion that Mexico will be the main rivals of the Bundesteam in the FIFA World Cup group.Ahead of the beginning of the World Cup in Russia, ter Stegen has revealed he sees Marco Fabian and Carlos Salcedo’s Mexico challenge Germany in the group as they have already been announced. He said they should not be underestimated.“Every one of us wants to win the World Cup and to do this, we want to get into the tournament with good feelings and with a good result against Mexico,” ter Stegen said, according to the official website of the Bundesliga.“They are the strongest team in our group, together with us, and they’ve come a long way in recent years.”Ter Stegen: Messi deserves to decide his Barca future Andrew Smyth – September 13, 2019 Marc-Andre ter Stegen insists Lionel Messi has earned the right to decide his Barcelona future amid fears he could leave next summer.“We’re going to prepare well in the coming week and we want to prove that we are the best team in the group.”He also went on to add that he is ready to do anything for the big prize.“It’s difficult for me, but I am giving all my support to the team so that we can win the World Cup, which is all that I want.”“It’s not just about quality, but also fortune and your form on the day that matter,” he continued. “There are many good nations, like Brazil and Spain, who are always up there, but we hope to start with a victory.”
James Milner is urging his Liverpool teammates to step up their game after losing two successive games in the League and Cup ties.The Reds slumped to another 2-1 loss at Wolves in the cup on Monday after losing to Man City at the Etihad.With a trip to Brighton next, Milner expects his side to crank up the pressure on City by beating the Seagulls to go seven points clear before their clash with Wolves.“Back-to-back defeats isn’t really good enough for us but you have blips in a season,” said the 33-year-old via Sky.“It’s not something you want, especially at Liverpool, we know what’s expected. We have to make sure we bounce back and look at where we can get better.Top 5 Premier League players to watch for next weekend Tomás Pavel Ibarra Meda – September 11, 2019 With the international activity cooling down for the next month, we go back to the Premier League’s Top 5 players to watch this weekend.After…“It’s not about blips, they are expected but it’s how you respond and bounce back. You’ve seen the character in the squad over the last few years, and the players we have, to know we will bounce back.“It’s easier saying that but we have to do that at the weekend.”He said: “I should do better. The pitch all night was a bit tricky and lively. It’s the same for both teams. It was my mistake for the first goal and it’s cost us, if not it’s 1-1 and we get a replay.“It was a pretty good finish from their lad but they didn’t have many chances. We didn’t either but that’s what separated the teams, my mistake and a very good finish for the second goal.”
Brokers on Singapore Exchange (SGX) are finding it tough to survive amid falling trading volumes, reflected in the SGX’s drop in revenues and profit for the first quarter, the results of which were declared last week. The inability for traders to recover costs amid low trading activity has even prompted some of them to quit the business altogether.”It is just not worth it. My clients are not interested to trade. Business hasn’t been worse in the past 20 years and I have been through several market crises. Better to call it a day,” an SGX stockbroker told a columnist working for Singapore’s The Straits Times.Another stockbroker rued the S$1-billion threshold that is crucial to recovering costs and making money at the SGX. “Any time when the daily volume falls below $1 billion, I lose money because I can’t cover my fixed costs like rental and salaries for backroom staff. And hitting $1 billion in stock market turnover is now becoming the exception rather than the rule,” he told the columnist.The situation in Singapore is in sharp contrast to Indian stock markets that are witnessing a boom in initial public offerings (IPOs) and listings, in addition to a thriving debt market. Fundraising via IPOs crossed $2.9 billion early this month with more in the pipeline, taking the money raised via public issue to a six-year high.The Singapore Exchange (SGX) posted a 16 percent fall in net profit to S$83 million for the first quarter in FY2017, year-on-year, reflecting lower levels of market activity. The 16-year-old stock exchange had reported a net profit of S$93 million in the corresponding quarter last fiscal.Revenues dropped 13 percent to S$190.8 million from S$219.6 million in the year-ago period, while operating profit came 17 percent lower at S$97.2 million.”Our first quarter performance this year reflects lower levels of market activities, compared with a more volatile market a year earlier,” SGX CEO Loh Boon Chye said in a statement and warned of low trading volumes ahead.”Participants reacting and adjusting to slowing global economic growth, political uncertainties and implications of Brexit on the European economy could result in a period of relatively subdued trading volumes,” he added.
Messages are shown on a bulletin board at The Neighborhood Church in Chico, Calif., on Tuesday, 13 November 2018. Photo: APThe authorities have reported six more fatalities from a blaze in Northern California, bringing the total number of fatalities so far to 48 in the deadliest wildfire in state history.The announcement came Tuesday after authorities ramped up the search for more victims buried in rubble left by the blaze that incinerated the town of Paradise.Many friends and relatives of those living in the fire zone say they haven’t heard from loved ones. Some went to shelters looking for them.More than 5,000 firefighters are still battling the blaze that charred 195 square miles (505 square kilometres) since it started Thursday.The fire has destroyed about 7,700 homes and displaced 52,000 people.The statewide death toll from wildfires over the past week in California has reached 50.The president of a utility accused by some residents of starting a deadly wildfire in Northern California says there was a power outage about 15 minutes before the flames were reported.Landowner Betsy Ann Cowley says Pacific Gas & Electric notified her the day before the blaze that crews needed to come onto her property because the utility’s wires were sparking.Asked if sparks from a transmission line ignited the fire, PG&E President Geisha Williams told the Chico Enterprise-Record on Tuesday that “it’s too soon to tell.”Williams says the outage was at 6:15 a.m. Thursday and later an aerial patrol spotted damage around the transmission lines. She says the company sent a report to state agencies.She says the sparks are one of several “options” investigators are reviewing.Some victims sued PG&E on Tuesday, alleging it failed to maintain its infrastructure.Victims of California’s most destructive wildfire have filed a lawsuit accusing Pacific Gas & Electric Co. of causing the massive blaze.The suit filed Tuesday in state court in California accuses the utility of failing to maintain its infrastructure and properly inspect and manage its power transmission lines.The utility’s president said earlier the company doesn’t know what caused the fire, but is cooperating with the investigation by state agencies.An email to PG&E about the lawsuit was not immediately returned.PG&E told state regulators last week that it experienced a problem with a transmission line in the area of the fire just before the blaze erupted.A landowner near where the blaze began said PG&E notified her the day before the wildfire that crews needed to come onto her property because some wires were sparking.Authorities doing the somber work of identifying the victims of California’s deadliest wildfire are drawing on leading-edge DNA technology. But experts say older scientific techniques and deduction could also come into play.With the death toll from the Northern California blaze topping 40 and expected to rise, officials said they were setting up a rapid DNA-analysis system, among other steps.Rapid DNA is a term for portable devices that can identify someone’s genetic material in a couple of hours, rather than days or weeks.But more traditional methods, such as examining dental records, are often a first step. Partially, that’s because victims might have had dental X-rays but not personal DNA profiles. Other medical records — of bone fractures, prosthetics or implants, for instance — also can be helpful.As a huge wildfire burns in Southern California, residents who stayed behind in coastal communities cut off by road closures are getting supplies by boat.Gas, food, baby wipes and horse pellets are among the items brought ashore Tuesday in the Paradise Cove area of Malibu.Large boats arrived from Redondo Beach, about 25 miles (40 kilometres) to the south. Supplies were unloaded onto smaller boats and even surf boards. Some residents donned wet suits and swam ashore with cases of water and beer.The fire northwest of Los Angeles has charred 150 square miles (388 square kilometers) of brush and timber, but containment has increased to 35 percent. More than 400 structures have been destroyed.Some Malibu residents are being allowed to return Wednesday afternoon, but tens of thousands of people remain under evacuation orders.People are coming to shelters in Northern California in search of loved ones and neighbors who are missing after a deadly fire tore through the town of Paradise.Greg Gibson searched a shelter in Chico on Tuesday for information about his missing neighbors. He doesn’t know if they tried to leave or not but says the fire exploded so quickly that if they hesitated, they would have had trouble.It’s not clear how many people are unaccounted for in the fire that ignited last week. At least 42 people are dead.Harold Taylor says he barely made it out of his house alive Thursday morning. The 72-year-old Vietnam veteran who walks with a cane says he tried to convince his neighbor to get in his car with him, but the neighbor declined. He doesn’t know what happened to his friend.A fire official says crews have made “a lot of progress” in preventing a deadly Northern California from reaching Oroville, a town of 19,000 people.California forestry and fire protection operations department chief Josh Bischof said Tuesday that firefighters on foot and in bulldozers are working south of the town of Paradise. It was levelled by the blaze that started last Thursday.Officials had worried strong winds could spread the wildfire toward Oroville and the Oroville Dam, the nation’s tallest. Firefighters on Monday cleared brush and sprayed water on vegetation near the dam.Bischof says “we’re feeling a lot better about this area.”More than 5,000 firefighters are battling the fire that killed at least 42 people in Paradise and nearby communities.The daughter of one of three named victims from the Northern California wildfire says that Ernie Foss Jr. was a musician and former San Francisco resident who shared his love of music with others.A search and rescue workers search for human remains at a burned out trailer park from the Camp fire, Tuesday, 13 November 2018, in Paradise, Calif. Photo: APAngela Loo told KTVU-TV on Sunday that the family is devastated by the death of her father, one of at least 42 people killed by the fire.She says Foss moved to the town of Paradise eight years ago because of the San Francisco Bay Area’s high cost of living.Loo says he taught music from their home near the city’s famous Haight Street and turned their living room into a studio.KTVU reports Foss and his dog, Bernice, were found outside their home on a street where several other victims were also found.Foss had advanced lymphedema and could not walk.The Butte County sheriff’s office listed his age as 65, but records show he was 63.The son of a man who died in the Northern California wildfire says his father will be buried next to his wife in a cemetery in the small town where he died.The Butte County sheriff’s office identified 77-year-old Carl Wiley of Magalia as one of at least 42 who died in the fire.Magalia and the neighbouring town of Paradise were devastated by the fire.James Wiley says his father was a tire recapper for Michelin and described him as a stoic figure.The elder Wiley will share a headstone with his wife, Mary Lee. She died of cancer nearly three decades ago.Authorities say destruction from Southern California’s huge wildfire will be significantly higher than the 435 structures already counted as destroyed.Los Angeles county fire chief Daryl Osby said at a press conference Tuesday that authorities are assessing damage from the 150-square-mile (388-square-kilometer) Woolsey Fire. Personnel are checking many canyon areas by foot, which will take several days.Authorities say risk from the fire has dropped significantly, with people going home to many areas that were evacuated when the blaze broke out last Thursday.Planes and helicopters are attacking a huge flare-up in a mountain wilderness area on the Ventura County side of the fire.Ventura county fire chief Mark Lorenzen says winds are pushing those flames away from nearby communities and he’s confident they’re safe.Forecasters say rain could fall next week, raising concerns about mudflows.Authorities have identified only a fraction of the dozens of victims of a wildfire that has decimated a Northern California town.Jesus Fernandez, a 48-year-old Concow resident nicknamed “Zeus,” and his beloved dog “King” had been missing since the fire broke out Thursday.Family friend Myrna Pascua told The Sacramento Bee that Fernandez’s son was informed Monday that his father was found pinned between two cars.The wildfire that largely wiped out the town of Paradise has left at least 42 dead and destroyed thousands of homes and other buildings.President Donald Trump says there are more victims of the California wildfires “than anybody would ever even think possible.”Trump thanked firefighters, first responders and the Federal Emergency Management Agency for doing their jobs with “courage in the face of very grave dangers.”Dozens of people have died, thousands of homes have been destroyed and thousands of people have been evacuated and in the wildfires scorching both ends of the state.Trump spoke about the fires Tuesday at the beginning of a White House ceremony about the Hindu festival of lights.US interior secretary Ryan Zinke says he’s cancelled a planned trip to Asia at the direction of the White House and will instead travel to California to support efforts to contain the deadly wildfires scorching large areas of the state.Zinke said Tuesday he will visit the Northern California fire that wiped out the town of Paradise and killed 42 people. He will travel later to Southern California, where another fire is burning that has killed two people.Zinke says he plans to meet with California Gov Jerry Brown to offer the administration’s support.The move comes after president Donald Trump — Zinke’s boss — on Saturday blamed poor “forest management” for making California’s fires so big, deadly and costly.About 200 people who fled their homes following the most destructive wildfire in California history have packed into a Northern California church where counsellors, chaplains and nursing students from Chico State University were available to help.The Neighbourhood Church in Chico was one of more than a half-dozen facilities helping house people displaced by the blaze, which has killed at least 42 people.James Woods is a director at the church and said Tuesday it will stay open “as long as it’s needed.”Volunteers are cooking three meals a day, and there is a large bulletin board with information about missing people.Miley Cyrus and Liam Hemsworth lost their home in the deadly wildfire blazing California but are donating $500,000 to The Malibu Foundation through Cyrus’ charity, The Happy Hippie Foundation.A representative for Cyrus says Tuesday in statement to The Associated Press that the couple’s “community and state are very special to them and they want to give back to the place that has created so many beautiful memories for themselves and others.”Cyrus and Hemsworth’s home was in Malibu and burned by the big Southern California wildfire that killed two people.The statement says they “are very grateful to be safe along with their animals.”The statement says the donation “will be used for those in financial need, emergency relief assistance, community rebuilding, wildfire prevention and climate change resilience.”California regulators say initial testing has found no elevated levels of radiation or hazardous compounds after Southern California’s huge wildfire burned near a former nuclear test site in hills to the northwest of Los Angeles.The state’s toxic substance control department says its staff went to the site known as the Santa Susana Field Laboratory on Saturday and found that facilities that previously handled radioactive and hazardous materials were not affected by the fire.The organization Physicians for Social Responsibility said in statement Monday that it was likely that smoke and ash from the fire spread radiological and chemical contamination that was in soil and vegetation.But the state agency says its measurements on the site and in the surrounding community found no radiation levels above background levels and no elevated levels of hazardous compounds other than those normally present after a wildfire.The site was used for decades for testing rocket engines and nuclear energy research. One of its nuclear reactors had a partial meltdown in 1959. Battles over decontamination efforts have gone on for years, with neighbours blaming illnesses on the site.Fire crews battling a Northern California blaze that levelled a town and killed at least 42 people made gains overnight and prevented the blaze from advancing toward a town of 19,000 people.California’s forestry and fire protection department said Tuesday that firefighters held containment lines to slow the wildfire’s advance toward Oroville.Officials say more than 5,000 firefighters are battling the blaze that destroyed the town of Paradise and has charred 195 square miles (505 square kilometres) since it started Thursday. The blaze is 30 per cent contained.Milder winds of up to 25 mph (40 kph) are expected in the area Tuesday. But fire behaviour specialist at Cal Fire Jonathan Pangburn says the there’s plenty of bone dry vegetation ready to burn “really fast and hot.”The wildfire has destroyed more than 6,400 homes and displaced 52,000 people.Firefighters are working to extend containment lines around the vast area burned by a Southern California wildfire.The work to eliminate the threat from the so-called Woolsey Fire on Tuesday was happening as winds continue to cause high fire threats from metropolitan Los Angeles to San Diego County.Authorities have allowed more people to return home but several entire communities, including Malibu, remain under mandatory evacuation orders.The latest estimates show the fire spread over more than 146 square miles (378 square kilometres). The fire area is expected to be fully contained by Thursday.Authorities have said two people were killed in the fire and at least 435 buildings were destroyed.More than a dozen coroner search and recovery teams looked for human remains from a Northern California wildfire that killed at least 42 people, making it the deadliest in state history. Anxious relatives are visiting shelters and calling police hoping to find loved ones alive.Lisa Jordan drove 600 miles (1,000 kilometres) from Yakima, Washington, to search for her uncle, Nick Clark, and his wife, Anne Clark, of Paradise, California. Anne Clark suffers from multiple sclerosis and is unable to walk. No one knows if they were able to evacuate, or even if their house still exists, she said.Lisa Jordan says she’s staying hopeful and adds: “Until the final word comes, you keep fighting against it.”Butte county Sheriff Kory Honea updated the confirmed fatality number Monday night.The figure that is almost certain to spike following the blaze that last week destroyed Paradise, a town of 27,000 about 180 miles (290 kilometres) northeast of San Francisco.Authorities were bringing in two mobile morgue units and requesting 150 search and rescue personnel. Officials were unsure of the exact number of missing.

Journal information: Proceedings of the National Academy of Sciences (Phys.org)—A team of researchers affiliated with several universities in the U.S. has conducted a drilling study of Lake Malawi in South-East Africa and suggest their findings may help explain the large number of cichlid species that call the lake their home. In their paper published in Proceedings of the National Academy of Sciences, the team describes their drilling expedition, what the sediment samples showed and why they believe their findings may help explain the unusual number of related fish species.

Lyons, DOI: 10.1073/pnas.1512864112AbstractThe transport of moisture in the tropics is a critical process for the global energy budget and on geologic timescales, has markedly influenced continental landscapes, migratory pathways, and biological evolution. Here we present a continuous, first-of-its-kind 1.3-My record of continental hydroclimate and lake-level variability derived from drill core data from Lake Malawi, East Africa (9–15° S). Over the Quaternary, we observe dramatic shifts in effective moisture, resulting in large-scale changes in one of the world’s largest lakes and most diverse freshwater ecosystems. Results show evidence for 24 lake level drops of more than 200 m during the Late Quaternary, including 15 lowstands when water levels were more than 400 m lower than modern. A dramatic shift is observed at the Mid-Pleistocene Transition (MPT), consistent with far-field climate forcing, which separates vastly different hydroclimate regimes before and after ∼800,000 years ago. Before 800 ka, lake levels were lower, indicating a climate drier than today, and water levels changed frequently. Following the MPT high-amplitude lake level variations dominate the record. From 800 to 100 ka, a deep, often overfilled lake occupied the basin, indicating a wetter climate, but these highstands were interrupted by prolonged intervals of extreme drought. Periods of high lake level are observed during times of high eccentricity. The extreme hydroclimate variability exerted a profound influence on the Lake Malawi endemic cichlid fish species flock; the geographically extensive habitat reconfiguration provided novel ecological opportunities, enabling new populations to differentiate rapidly to distinct species. Scientists have debated amongst themselves the possible reasons for such a large number of cichlid species in one lake—over a 1000, which is more than any other lake. Possible ideas have included unknown environmental factors or biological tendencies of the cichlid in general. In this new effort, the researchers suggest it might have been because lake levels changed so dramatically over the years.To learn more, the researchers traveled to the lake and conducted drilling operations, collecting sediment samples that revealed lake level changes over the past 1.3 million years. In looking at the data, the team found that that there were approximately 24 dry periods where the lake level dropped at least 650 feet and multiple periods where excessive moisture caused the lake to overflow into the surrounding area. There was also a big change that occurred approximately 800,000 years ago where the climate shifted from one that was mostly dry, to one that was much wetter. They noted that during some of the low level periods the lake likely broke into several pieces.The researchers suggest that such dramatic fluctuations in lake levels could account for the huge number of cichlid species, a dominant fish that would have had to be able to change quickly to adapt to new conditions—lower lake levels, for example, would have meant the water would have been a lot saltier with dramatically different pH levels, and if the lake broke up for long periods of time it would have led to isolation of some species.If the theory by the team is correct, it still does not explain, as they acknowledge, how it was that so many of the species that developed managed to survive till today. That answer will likely take a genetic study.

Electrospun core-shell microfiber separator with thermal-triggered flame-retardant properties for lithium-ion batteries, Science Advances (2017). DOI: 10.1126/sciadv.1601978AbstractAlthough the energy densities of batteries continue to increase, safety problems (for example, fires and explosions) associated with the use of highly flammable liquid organic electrolytes remain a big issue, significantly hindering further practical applications of the next generation of high-energy batteries. We have fabricated a novel “smart” nonwoven electrospun separator with thermal-triggered flame-retardant properties for lithium-ion batteries. The encapsulation of a flame retardant inside a protective polymer shell has prevented direct dissolution of the retardant agent into the electrolyte, which would otherwise have negative effects on battery performance. During thermal runaway of the lithium-ion battery, the protective polymer shell would melt, triggered by the increased temperature, and the flame retardant would be released, thus effectively suppressing the combustion of the highly flammable electrolytes.

Adv. 2017;3:e1601978 Reports of phones and hoverboards catching fire due to short circuits in batteries have caused alarm in the personal electronics industry—both by users and those that make the devices. Unfortunately, up until now, engineers have not been able to solve the problem completely. Most such efforts involve re-engineering devices to prevent short-circuiting and thus overheating, or attempting to put flame retardant directly in the batteries. Neither approach has proven to be entirely satisfactory. Re-engineering does not always solve the problem and the addition of flame retardant greatly reduces battery efficiency. In this new effort, the researchers describe an approach that thus far appears to offer some help—it does not stop overheating from occurring, but it is able to prevent fire.The new approach involves encapsulating a common flame retardant called triphenyl phosphate in an extremely tiny sheath made of plastic fibers and then inserting several of them into the electrolyte that sits between the anode and cathode. The sheath keeps the retardant from actually coming into contact with the electrolyte material, which is flammable and the source of most battery fires. But the plastic fibers in the sheath have a melting point of 160° Celsius—if that temperature is reached, the plastic melts and the retardant is released into the electrolyte quashing a potential fire. Journal information: Science Advances In test devices using their encapsulated flame retardant, the researchers report that the sheaths melted and the retardant was released and merged with the electrolyte in just 0.4 seconds and because of that fires were averted.In practice, it is presumed that such an occurrence in a device would initiate a hardware error before the battery stopped working to alert a user to what had occurred. Thereafter, a user would also presumably have to purchase a new battery in order to continue using their device which would survive the overheating event.
