In frustration, OSU’s leading scorer shoved an opposing player and was charged with a technical.“It was a lot of extra stuff going on after the play was over, so I think that got to me a little bit,” Ross said after the game. “So that was the reason for the technical foul, a little frustration. But after that I was just trying to win the game.”Despite Nebraska scoring six straight points after the foul, taking an 18-point lead in the process, the Buckeyes would storm back on the shoulders of Ross and sophomore guard Amedeo Della Valle.OSU outscored Nebraska 41-25 after Ross was hit with the technical, and held on for a 71-67 victory.Junior forward Sam Thompson — who tallied seven points in the win — said the technical brought an end to Nebraska’s tough play, and turned the game around.“We thought they were playing a little bit too physically,” Thompson said after the game. “They got some shots at us after the whistle was blown, we didn’t like how they were dancing on the bench, just the whole vibe we didn’t like that. (LaQuinton’s) technical brought it to an end, we were able to rally around that.”This wasn’t the first time this season Ross’ been given a technical foul for shoving a player, having gotten one against Northwestern that led to his ejection and then another against Indiana.“Unfortunately that’s a little familiar,” Craft said after the game against Nebraska. “He’s done that a couple times this year. I just think after the whistle, they catch the second guy. He threw an elbow and hit him in the face after the play … and they’re going to catch LaQuinton.”But Craft said, unlike in previous incidents, this foul served as a motivator for OSU.“It was kind of like an NBA game. (A) player or coach gets fired up and you get ejected and you start rallying around him,” Craft said. “I don’t condone that because that got us down 16 at one point. They made the free throws and got a bucket. We don’t want that to happen, but if it works out, it works out.”After picking up a technical caused by emotion — much like the one Ross picked up — coaches often elect to bench the player to give them some time to calm down.But OSU coach Thad Matta elected for the opposite, leaving Ross on the floor and giving his leading scorer a chance to bring his team back from the brink of elimination.Ross went on to score 16 of his career-high 26 points after the technical foul, including the 3-pointer that started the run.“That play was over,” Ross said of the technical foul. “I wasn’t thinking about that play again. I looked up at the score and how bad we were down and we just had to get some motivation and get back in the game.”Ross added that the comeback was partially because of OSU refusing to lose control.“We stayed together through the whole thing,” Ross said. “There was never any panic during the whole situation. If you watch some of our games earlier in the year, we (were) down less points than that, I think we were down 18 here. A couple games, like Minnesota, we (were) probably down five and we panicked. But that game right there we (were) able to not panic and got through it.”Next up Ross and the Buckeyes will look to push themselves past top-seeded Michigan Saturday at Bankers Life Fieldhouse in the semifinals of the Big Ten Tournament. Tipoff is set for 1:40 p.m.
AC Milan signed Pepe Reina from Napoli as a free player as his contract with the Partenopei is about to expire after the end of this season – but he isn’t coming as a replacement of Gianluigi Donnarumma.After the Spaniard had been signed, the speculations about the departure of the young keeper started to spread around – but sporting director Mirabelli denied that there is anything true about it.Mirabelli spoke about Donnarumma’s situation as he said, according to acmilan.theoffside.com:Maurizio Sarri satisfied despite Juventus’ draw at Fiorentina Andrew Smyth – September 14, 2019 Maurizio Sarri was satisfied with Juventus’ performance on Saturday afternoon after finishing a tough game at Fiorentina 0-0.“We had the opportunity to get him for free – and we think it was useful strategically. We’ll have a lot of competition, Reina can help us off the pitch, in addition to his contribution on it. We need people with experience and he’s one of those.””I already told your other colleagues [in the media] that it’s not just down to Donnarumma, it involves everyone. A player has to come to us and tell us he doesn’t want to stay. That’s not the case with Donnarumma.”
The national team manager believes he has already detected the mistakes his squad committed in the 2018 FIFA World Cup editionThe 2018 FIFA World Cup in Russia is seen as the worst tournament Germany has ever participated in.The national team failed to advance from its group and ended up at the bottom of the block.But for manager Joachim Low, he has four years to work on what can lead Germany to be world champions again.“This time we missed a little bit with our emotions, our fire – some players were not at their top level,” Low told the BBC World Football Show.Top 5 Bundesliga players to watch during the weekend Tomás Pavel Ibarra Meda – September 11, 2019 With the international activity cooling down for the next month, we go back to the Bundesliga’s Top 5 players to watch next weekend.The German…“It was a shock. We have to learn from that and accept that.”“We are re-motivated. We were four years at the top level, we won the World Cup in 2014 and the Confederations Cup in 2017. If you want to win the World Cup again, everything has to be perfect,” he added.“We have to accept our results but we’re looking forward. We know we have a good team of motivated players. We will come back again.”“It’s always a challenge in Germany, everyone expects you to win a tournament. But we had a very good last 10 or 12 years. This time it was bad but we are sure we will be better in the future,” Low said.“[German FA director] Oliver Bierhoff and I met immediately after the World Cup. For 14 years we were responsible for the team and for the organization in this federation.”
Former Bayern Munich defender Markus Babbel fears that the internal pressure that coach Niko Kovac has from the club board could lead to an early end of his reign in chargeThe pressure is mounting on the Croatian with Bayern currently on a four-game winless run in all competitions.Last time out the Bundesliga champions suffered a shock 3-0 home defeat to Borussia Monchengladbach and are now sixth in the league table and four points behind leaders Borussia Dortmund.Bayern president Uli Hoeness has already announced that he will defend Kovac to the end.But Babbel knows first-hand how big the pressure of getting Bayern back on track will be for Kovac.“The problem is if you work in a club like Bayern, not only the press will put pressure but within the club too,” Babbel told SportsMax. “I know from my time there. Nothing changed.“Players can go to Hoeness or Rummenigge. Then you as a coach you have no chance because they’re crying here and there. This is the biggest problem. You have two big men in the office. If they don’t support you, you have no chance.”“For me, it is not normal. You can’t start with seven wins then play a draw against Augsburg,” Babbel said. “They had chances to win the match but Manuel Neuer made a mistake. From there, everything has gone the wrong way.“It’s very strange. I don’t know what’s happened. I know the coach is good, the players are good. If they are fine together, they will bounce back and win games.”Harte Arbeit und gute Laune zum Wochenstart bei @R13_official und Leon #Goretzka! ☀💪 #packmas #MiaSanMia pic.twitter.com/GZm21lyKg9Merson believes Arsenal should sign Sancho Manuel R. Medina – September 14, 2019 Borussia Dortmund winger Jadon Sancho might be the perfect player to play for the Gunners, according to former England international Paul Merson.— FC Bayern München (@FCBayern) October 15, 2018Babbel, who now manages Australian club Western Sydney Wanderers after retiring in 2007 from playing football, questioned the motivation levels of the Bayern squad.“Problems not only at Bayern but Manchester United. Players aren’t recognising who they are playing for anymore,” said Babbel.“The privilege to play for a club like this. How much money they earn. They’re not performing and giving everything. They’re not top professionals.”He added: “From the outside, maybe the team is a bit too old. They’ve been playing together for a long time. I watched them last season live and they didn’t look hungry anymore… Too many players at Munich have stayed for too long.“There’s not much fresh air in the team. It’s always the same. Maybe this is one of the reasons things aren’t working.”Babbel won nine trophies in total at Bayern, which included three Bundesliga titles and the UEFA Cup in 1996 before leaving for Liverpool in 2000.
Paris Saint-Germain goalkeeper Gianluigi Buffon expects a stern challenge from Napoli in next week’s Champions League gameThe Ligue 1 champions will travel to Naples for Tuesday night’s Group C showdown.Currently, PSG lies only third in the group table at the halfway stage with Napoli a further point ahead in second.Therefore, PSG coach Thomas Tuchel announced that he will reinstate Buffon in goal ahead of their key clash.It will mark the first time Buffon’s returned to his native Italy since his summer departure from Juventus.“It will be a delicate match against a very high-level opponent,” Buffon told Sky, via Football-Italia.PSG ultras sent a warning letter to Neymar Manuel R. Medina – September 14, 2019 Brazilian superstar Neymar might play today his first game of the season for Paris Saint-Germain and the team’s ultras have warned him.“The arrival of [Carlo] Ancelotti means this team now has a certain awareness that it’s not certain they would have had before.”The 40-year-old keeper is still reeling from last season’s sending off in the Champions League.Referee Michael Olivier handed Buffon a straight red card after strongly protesting his decision to award Real Madrid a late penalty in Juventus’ semi-final defeat.“I suffered,” Buffon admits.“I watched on TV in the dressing room, not being able to participate makes me suffer.”
On the eve of the Premier League derby at Stamford Bridge against Manchester City, Chelsea chief Maurizio Sarri asked for patience after his team suffered two defeats in their last three Premier League outingsAfter an outstanding start of the season, the Blues have struggled to maintain the impressive performance in the past few weeks, having failed to secure all three points in three out of their previous four league clashes.After running unbeaten in 18 games across all competitions, the London outfit has suffered a 3-1 defeat to Tottenham Hotspur at the Wembley Stadium. What’s more, they allowed the returnees, Wolverhampton Wanderers, to come back from a goal down and clinch a 2-1 victory last midweek.However, former Napoli manager believes he needs to get some time to help his side return to the top of the Premier League.“What happens if Guardiola had no time in City? Maybe the best team in the world (would not have been) City in the last year,” he told Evening Standard.“My problem is to improve my players, to solve the situation, to solve problems, to try to gain a lot of points.Pochettino admits Wanyama remains in his Spurs plans Manuel R. Medina – September 14, 2019 Kenyan international, Victor Wanyama, was the protagonist of a summer transfer saga, but in the end, he is set to stay at Tottenham Hotspur.“Then there is the club that will decide what is better for them.“For him (Guardiola), it’s impossible to improve 20 players in the first season.“He told me, in the first season, you have to work only on 14, 15 players otherwise you are in trouble.“You need a season just to understand the real situation here (in England).”With Chelsea expected to take on the Citizens on Saturday’s afternoon, Maurizio Sarri is poised to take Guardiola’s scalp as his team trails the unbeaten Premier League leaders by ten points.
The new material, which is a polycrystalline silicon nanowire, breaks two limits: the Casimir limit and the amorphous limit. The Casimir limit is a theory that describes the thermal conductivity of nanostructures, and breaking it means that the thermal conductivity of the new material is lower than the value predicted by Casimir limit theory. The amorphous limit is regarded as the lowest thermal conductivity of a material, since amorphous structures strongly scatter heat carriers. However, due to its unique nanoscale design, the polycrystalline silicon nanowire has a thermal conductivity that is three times lower than that of amorphous silicon materials.The researchers, Yanguang Zhou and Ming Hu at RWTH Aachen University in Germany, have published a paper on the polycrystalline silicon nanowire in a recent issue of Nano Letters.The researchers expect that the new material could be especially useful for thermoelectric applications. By converting heat energy into electricity, thermoelectric materials provide a way to capture some of the waste heat emitted by vehicle tailpipes, power plants, and manufacturing facilities, and then convert the heat into useful energy.In general, good thermoelectric materials are those that simultaneously have high electron conductivity and low thermal conductivity. Together, these two properties lead to a high overall heat-to-electricity conversion efficiency. In the new study, the researchers focused on decreasing the thermal conductivity while maintaining the already high electron conductivity of silicon materials. “In this paper, we report a new structure, polycrystalline nanowire, which can reduce the thermal conductivity to a record low value, only one-third of its amorphous counterpart,” Zhou told Phys.org. “If we keep the electric conductivity and Seebeck coefficient as constants, which can be achieved by doping the material, the efficiency of the polycrystalline nanowire to convert heat to electricity can be enhanced by 277 times with respect to its bulk counterpart.” Engineer creates new technique for testing nanomaterials (Phys.org)—Researchers have theoretically demonstrated the lowest rate of heat transfer, or thermal conductivity, in any silicon-based material developed so far. The key to the new silicon nanowire’s low thermal conductivity is its polycrystalline form, which consists of many crystal structures of varying shapes and sizes in random orientations. Based on the average grain size (about 3 nm) in the polycrystalline silicon nanowires, the Casimir limit predicts that the thermal conductivity cannot be below approximately 3 W/mK. But the researchers’ simulations show that the polycrystalline silicon nanowires have a thermal conductivity of just 0.7 W/mK. For comparison, this value is 269 times lower than that of bulk silicon, 77 times lower than that of pristine silicon nanowires, and three times lower than that of amorphous silicon nanowires.The researchers explain that an important feature of the polycrystalline structure is that the grain boundaries between crystals are discontinuous. As a result, the grain boundaries block and scatter the heat-transporting phonons, so that the phonons cannot move very far (only about 1 nm) through the material compared to how far they can move in other silicon materials (up to 1 µm), in which the grain boundaries form a continuous network. The results here raise the question of what the lowest possible thermal conductivity may be for silicon nanowires of any form. In general, there are two kinds of vibrations that contribute to thermal conductivity: propagons and diffusons. The researchers expect that it should be possible to completely eliminate the contribution of propagons by incorporating disorder in the form of nanotwinned structures into the polycrystalline silicon nanowires to minimize their transport. Diffusons, on the other hand, are caused by the inherent structural disorder of a material, so they cannot be reduced in this way. Nevertheless, by eliminating the contribution of propagons, the researchers expect that the thermal conductivity of the polycrystalline silicon nanowires can be further reduced by 20%. The researchers plan to pursue this goal in future work. © 2016 Phys.org Explore further More information: Yanguang Zhou and Ming Hu. “Record Low Thermal Conductivity of Polycrystalline Si Nanowire: Breaking the Casimir Limit by Severe Suppression of Propagons.” Nano Letters.
