Breaking the ice before it begins

first_imgEngineers from Harvard University have designed and demonstrated ice-free nanostructured materials that literally repel water droplets before they even have the chance to freeze.The finding, reported online in ACS Nano on Nov. 9, could lead to a new way to keep airplane wings, buildings, power lines, and even entire highways free of ice during the worst winter weather. Moreover, integrating anti-ice technology right into a material is more efficient and sustainable than conventional solutions like chemical sprays, salt, and heating.A team led by Joanna Aizenberg, Amy Smith Berylson Professor of Materials Science at the Harvard School of Engineering and Applied Sciences (SEAS) and a core member of the Wyss Institute for Biologically Inspired Engineering at Harvard, focused on preventing rather than fighting ice buildup.“We wanted to take a completely different tact and design materials that inherently prevent ice formation by repelling the water droplets,” says Aizenberg. “From past studies, we also realized that the formation of ice is not a static event. The crucial approach was to investigate the entire dynamic process of how droplets impact and freeze on a supercooled surface.”In comparison with traditional ice prevention or removal methods like salting or heating, the nanostructured materials approach is efficient, non-toxic, and environmentally friendly. Further, when chemicals are used to de-ice a plane, for example, they can be washed away into the environment and their disposal must be carefully monitored. Similarly, salt on roads can lead to corrosion and run-off problems in local water sources.The researchers anticipate that with their improved understanding of the ice forming process, a new type of coating integrated directly into a variety of materials could soon be developed and commercialized.last_img read more

Spurs hit back to stun Baggies

first_imgWest Brom threw away a three-goal lead as Christian Eriksen’s late strike saw Tottenham secure a Barclays Premier League point at The Hawthorns. For the second successive home game, the Baggies were held to a 3-3 draw due to a stoppage-time goal, Eriksen rounding Steven Reid and smashing the ball past Ben Foster deep into the additional period. Albion had looked to be cruising towards three points in the early stages, racing into a 2-0 lead through strikes from Matej Vydra and Chris Brunt in the first and fourth minutes respectively. The subsequent effort from the spot by Adebayor was tame and Foster was able to get down to his left to keep it out. Spurs had an escape in the 26th minute when Amalfitano, allowed considerable space in the area, received the ball from Youssouf Mulumbu and drilled it at Lloris, who pushed it over the bar. But after Paulinho sent the ball into Foster’s arms from distance, West Brom’s third then did arrive and once again Tottenham did themselves no favours in the build-up. Olsson’s long hopeful ball forward from defence was headed backwards by Kaboul and taken by Sessegnon, who drove forward while holding off Vlad Chiriches before slotting beyond Lloris. While the West Brom fans gleefully chanted at Tottenham boss Tim Sherwood that he was going to be sacked in the morning, their Spurs counterparts barely knew what had hit them. However, their hopes of a comeback were soon boosted. Only three minutes after Sessegnon’s strike, the away side had a goal back when Olsson diverted a cross into the box past his own goalkeeper. And moments later Foster pulled off a great double save, pushing away Paulinho’s shot before denying Rose on the rebound. Tottenham kept up the pressure after the restart and after Rose put an attempt wide, Foster produced further heroics, palming behind an Aaron Lennon strike and then jumping to keep out a lofted Eriksen free-kick. Rose was in the thick of the action once again when he went down in the West Brom area claiming a foul by Reid, only to pick up a booking from Swarbrick for his trouble. Kaboul then escaped punishment for a collision with Foster which he appeared to have gone into with a slightly high foot. Spurs kept up the tempo and in quick succession Kane saw his marker just beat him to one cross in front of goal and then narrowly failed to stretch enough to connect with another. The striker had his goal within a few minutes, though, rising to head in from Lennon’s cross. Eriksen then skewed off-target and Rose smashed over as Tottenham hunted down an equaliser. And it came in dramatic circumstances as the ball came to Eriksen in the box after a cross was flicked on and the midfielder got the better of Reid before cracking the ball into the net. Press Association After Foster had saved a tepidly-struck penalty from Emmanuel Adebayor, Stephane Sessegnon then capitalised on a Younes Kaboul error to make it 3-0 in the 31st minute. But Tottenham rallied impressively and following Jonas Olsson’s own-goal in the 34th, Harry Kane headed in with 20 minutes to go before Eriksen fired in his leveller at the end. It meant West Brom boss Pepe Mel, whose side drew 3-3 with Cardiff in their last Hawthorns encounter, was once again denied his first home win since taking over in January. And having passed up this opportunity, Albion are now only three points clear of the relegation zone in 16th place with five games to go – albeit, one more than the three sides below them. Spurs, meanwhile, are sixth, four points behind fifth-placed Arsenal and six behind fourth-placed Everton, with both those sides having a game in hand over them. West Brom made a flying start. Less than 30 seconds had elapsed when Morgan Amalfitano well and truly outwitted Danny Rose on the right and put a ball into the box that Hugo Lloris could only push to Vydra, who hooked it into the net. Albion swiftly added another, taking advantage of sloppy play at the back by Spurs as Reid’s cross dropped to Brunt via a flick-on and the Baggies skipper volleyed home sweetly. Tottenham looked to hit back quickly and after Kane had fired an attempt wide, the visitors were awarded a penalty around the quarter-hour mark when referee Neil Swarbrick ruled Amalfitano had fouled Rose in the West Brom box. last_img read more

Trojans win on walkoff in tenth inning

first_imgSenior centerfielder Timmy Robinson rejoiced as he strutted to first base after collecting his second walk-off hit already in this baseball season, when his single to left field in the bottom of the tenth inning scored redshirt sophomore Frankie Rios.The baseball team survived the Pepperdine Waves in dramatic fashion Tuesday night winning 6-5 in an eventful game that involved five lead changes and 24 hits from the two teams to improve the Trojans to a 13-14 record.After being named Pac-12 Player of the Week for his team high .462 batting average last week, Robinson said that his goal for the remainder of the season is to remain consistent and focused on the field.“I just wanted to put the ball in play,” said Robinson. “A strikeout does nothing there. I got a little anxious early in the count, but I just stuck with it and he eventually gave me a fastball which I could do something with and just stayed over it and found the hole.”USC’s first run was scored by junior leftfielder Corey Dempster who led off with a double. Two ground balls advanced him to home with the RBI going to junior catcher Jeremy Martinez.After allowing one hit in the first inning, USC freshman pitcher CJ Stubbs let up the first 2 runs for the Waves in the second after hitting a batter that led to one run being scored on a single to right field. After another single from Waves freshman leftfielder Matthew Kanfer allowed Pepperdine to bring 1 run in but a second was stopped from scoring after Martinez tagged him out at home plate.USC responded in the bottom of the second inning and tied the game at 2 runs a piece after back-to-back singles from sophomore third baseman Adalberto Carrillo and Ramirez. Dempster singled to right field to score 1 run and the inning ended when a second runner was cut down at the plate.Stubbs allowed 4 runs on seven hits through five innings against the Waves. He also posted six strikeouts. After Stubbs was pulled, the pitching combination of seniors Brent Wheatley, Marc Huberman and Brooks Kriske only gave up 1 run through the remaining five innings.Head coach Dan Hubbs was pleased with the results from his bullpen.“What I was really excited about was just to see Brent [Wheatley] to come in and pitch two scoreless,” Hubbs said. “You know, he has been scuffling, and I think he is starting to turn the corner, and we are going to need that because we are going to need him to become a big part of what we do.”The Trojans took their second lead of the contest in the fourth inning after Carrillo initiated the Trojans’ offense with a leadoff double. Carrillo advanced to third base thanks to the efforts of senior first baseman AJ Ramirez’s sacrifice bunt, and scored the only run of the inning as a result of a single from freshman first baseman Dillon Paulson.USC tied the game in the bottom of the fifth when a Martinez single to right-center field scored senior outfielder David Oppenheim who had doubled to right field as the previous batter. Martinez had three hits on five at-bats leading to two RBI’s.Robinson scored in the sixth to give the Trojans the lead once more when Carillo hit a sacrifice fly to right center. Two scoreless innings would ensue until Pepperdine’s junior shortstop Manny Jefferson hit a solo home run to left field.The game went to extra innings where Kriske closed without allowing a run in the tenth. The second batter of the inning for Pepperdine was sophomore second baseman Chase Lambert who singled before advanced to second base on a wild pitch. Lambert advanced to third on a ground out. With two outs, Kriske hit the batter, junior centerfielder Jeremy Goldentz. With two runners on base and a full count, Matthew Kanfer grounded out to third, and USC escaped.The leadoff batter was Oppenheim who was walked. Rios entered the game as a pinch runner, and Martinez hit a single to left field that allowed Rios to advance to third. The walkoff hit came from Robinson when he hit a single to left field. Rios scored ending the game.last_img read more
