His 35 power play goals are tied for fifth over that same stretch, and his power play points are good for third.The New York Rangers ranked 10th in the league in power-play percentage last season, and that should only improve with the addition of hometown1He’s from nearby New Rochelle. boy Shattenkirk. The newly minted Rangers defenseman chews up big minutes, and he’s never finished a full season with a Corsi For percentage of less than 51.2. For the uninitiated, a Corsi For score of more than 50 percent means the player’s team was controlling the puck more often than not when he was on the ice, so the addition of Shattenkirk should make the Rangers a stronger possession team from the jump.Over the past five seasons, the bulk of the blame for each Rangers playoff ouster seems to have pointed back to the blue line. With a mishmash of overworked veteran defensemen and disappointing acquisitions, the Rangers sit roughly in the center of the pack in shots allowed per game over the past five seasons. Adding a puck-moving defenseman who is entering his prime with better-than-average possession numbers should help decrease those shot totals — and take some of the burden off the suddenly human-appearing goaltender Henrik Lundqvist’s shoulders.The Rangers’ defensive corps will look different with the retirement of Kevin Klein and longtime defenseman Dan Girardi going to Tampa Bay, but the franchise that hasn’t had a legitimate defensive star since Brian Leetch landed a big upgrade in Shattenkirk.Justin Schultz, Pittsburgh Penguins (re-signed)Justin Schultz’s career began with so much promise. In the lockout-shortened 2012-13 season, he scored 27 points from the blue line as a 22-year-old rookie. But in the 2.5 seasons that followed, he failed to match the impressive points-per-game numbers he put up as a rookie, and people in Edmonton began to sour on him. Oh what a difference a few seasons and some new scenery make.Since joining the Penguins, Schultz has transformed into a top-line defenseman, and he was a key piece to their Stanley Cup-winning campaign last season. In less than two seasons with Pittsburgh, he’s scored 0.61 points per game from the back,2He produced 0.41 points per game during his time in Edmonton. and he’s driven possession at a better clip, too.Of the free agents in the 2017 class, Schultz’s goals above replacement3Goals above replacement aims to estimate the number of net goals a player produces compared to a replacement-level player in the same amount of ice time. (The replacement level represents the amount of production a team could expect from a minimum-salary player at a given position.) mark of 13.9 ranks at the top. Pittsburgh may have lost Trevor Daley to free agency, but a defensive core built around Schultz and a healthy Kris Letang is nothing to turn your nose up at.Justin Williams, Carolina HurricanesThe Carolina Hurricanes were pretty close to making the playoffs last season. They ended up falling eight points short of an eighth seed but were in the hunt until the last few weeks of the season — and if they make the 2018 postseason, they’ll be glad they signed Justin Williams. Williams is well-known around the league for being a playoff beast. His career playoff points per game rate of 0.67 is better than his regular-season rate of 0.63, and he’s tied for 14th among active NHL players in game-winning playoff goals — and he’ll be returning to the place where he lifted the first of his three Stanley Cups, and where he twice netted 30-plus goals.Ten times in his career, Williams has scored 40 or more points, which should help a Carolina team that finished in the bottom third of goals scored last season. Oh, and Williams can do more than score timely playoff goals; his career Corsi For percentage of 56.9 isn’t too shabby either.Alexander Radulov, Dallas StarsAlexander Radulov is … mercurial. The Russian winger has been on alternating stints between the NHL and Russia’s KHL for his entire professional career: two seasons in Nashville, four in Salavat, a few more weeks in Nashville, four seasons in Moscow and then one in Montreal. So after his 54-point campaign with the Canadiens last season, he was bound to go anywhere from British Columbia to Siberia. He chose Texas. He’ll be there for a while, too, signing a long-term deal with the Dallas Stars. (Radulov’s signing in Dallas can also be read as a rebuff of KHL league chairman Arkady Rotenberg — and his close friend Vladimir Putin — who hopes to pry as many Russian players away from the NHL to ensure eligibility for the 2018 Winter Olympics in South Korea.)But Radulov is a world-class scorer — he’s tallied 156 points in 230 NHL games and scored 492 points in 391 KHL games — and was by all accounts a great teammate in Montreal, so the Stars were lucky to land the big sharp-shooting right winger. Pair Radulov’s propensity for burying the puck with an insanely talented top line of Tyler Seguin and Jamie Benn, and the Stars might have on their hands the highest-scoring top line in the NHL next season.Patrick Marleau, Toronto Maple LeafsThe Toronto Maple Leafs were a formidable offensive force last season, ranking fifth in total goals scored. The Leafs got a ton of scoring — 32 percent of their 250 goals — from their three rookie sensations: Calder Trophy-winning Auston Matthews, Mitch Marner and William Nylander. Patrick Marleau will make the Leafs’ offense only more dangerous, and you could do worse as far as mentor figures go.Marleau, 37, has been in the NHL for 19 seasons, and until now he’s never worn anything but “deep Pacific” San Jose teal. In his 19 seasons, he’s made a point of scoring at least 19 goals — he’s only failed to do so three times, and one of those seasons was shortened to 48 games by a lockout. Marleau has also played in 177 playoff games, experience that should help the upstart Leafs — who gave the mighty Washington Capitals a serious scare in the first round of last season’s playoffs — immensely.Joe Thornton, San Jose Sharks (re-signed)“Jumbo” Joe Thornton is easily one of the best passers in NHL history. And he is certainly the best passer in NHL history who has a beard that is probably sentient. One of the premier centers of his generation, Thornton trails only Jaromir Jagr — who himself remains mysteriously unsigned — on the active assists leaderboard.4He also ranks 13th all time and needs just 43 more to leapfrog Gordie Howe as the ninth-highest dime-disher in NHL history. Jumbo hasn’t scored fewer than 50 points in a full season since he was a 19-year-old playing for the Boston Bruins in 1998-99.He’s not going to score a ton of goals — never really has — but San Jose was probably smart to prioritize Thornton over his longtime teammate Marleau. (Fun fact: Thornton and Marleau went first and second, respectively, in the 1997 NHL draft.) Thornton isn’t the lights-out goal scorer Marleau is, but he creates more opportunities for his teammates than his longtime counterpart; 43 of Jumbo’s 50 points were assists, 18 of which came on the power play. For a team that struggled mightily on the power play last season — San Jose ranked 25th in the league — the Sharks will need all of the passing acumen they can muster with the man advantage next season.Ryan Miller, Anaheim DucksRyan Miller probably won’t play much in Anaheim — starter John Gibson is just 23 years old and had a spectacular 2016-17 season — but there aren’t many teams in the NHL that can say they’ve got a backup who was once considered among the best goalies on the planet. Miller’s numbers were down a bit last season, but you can’t really blame him — his Vancouver Canucks gave up the sixth-most shots of any team in the league. Despite his impressive résumé, Miller might have to battle with Reto Berra for the backup position in Anaheim. Still, though, the Ducks are in great shape between the pipes — there aren’t many teams in the NHL that have the luxury of choosing from three proven(ish) NHL goaltenders.Karl Alzner, Montreal CanadiensAndrei Markov, unsignedThe Washington Capitals probably didn’t have the cap space to re-sign longtime defenseman Karl Alzner, but they probably didn’t really care to either. No worries for Alzner, though, because the Habs delivered a pretty solid payday. But truth be told, the native of Burnaby, British Columbia, got an awful lot of money — a cap hit of $4.6 million a year, to be exact — for a guy whose Corsi For percentage ranked 184th out of 229 qualified5With a minimum of 20 games played. defensemen in 2016-17.Alzner actually doesn’t do a whole lot very well — in 82 games, he scored just 13 points, zero of which came on the power play. He’s still relatively young for a defenseman — he’ll turn 29 before the 2017-18 season begins — and so perhaps Les Habitants are hoping Alzner’s game has room to grow. But that doesn’t change the fact that they signed a guy whose possession stats are subpar to a lucrative deal while their longest-tenured player — Andrei Markov — remains seated on the bench, waiting to see if he’ll play in Montreal next season.Markov is old, but if last season’s performance is any indicator, he still has some gas left in his tank. Markov was limited because of injury but put up impressive numbers in the 62 games he did play in. At 38, and still playing more than 21 minutes per game, he drove possession at the best rate of his career. He also scored 36 points from the blueline, good for .58 points per game.6Markov’s career points per game rate? .58.In 16 NHL seasons, Markov has only ever worn a Habs jersey. Montreal would be foolish not to re-sign their longest-tenured player.

Rather, NHL free agency has been a methodological redistribution of assets — one that can be traced to the addition of the Vegas Golden Knights and the expansion draft that ensued. All that extra movement of bodies and money, coupled with every general manager’s rush to add or retain a free-agent gem, means there will be a lot of familiar faces in unfamiliar jerseys next season.Not every free agent has signed — in particular, this year’s rather elderly free-agent class has a few graybeards who remain without suitors — but most of the league’s big targets have decided where they’ll play next season.

One way to do this is to use ammonia as a hydrogen source. However, discovery of an efficient process for breaking down ammonia has proved difficult, largely because the catalytic process to break down ammonia requires the continuous addition of heat, which can be prohibitively expensive.Katsutoshi Nagaoka, Takaaki Eboshi, Yuma Takeishi, Ryo Tasaki, Kyoto Honda, Kazuya Imamura, and Katsutoshi Sato of Oita University in Japan have developed a method using a novel catalyst for producing hydrogen from ammonia without the addition of external heat through the catalytic cycle. Their work appears in Science Advances.The decomposition of ammonia into hydrogen and nitrogen is an endothermic process, meaning that it requires the addition of energy to obtain products. This means that traditional catalytic decomposition reactions require the addition of a large amount of heat to obtain a useful amount of hydrogen gas.Nagaoka et al. developed a catalyst that is made of a RuO2 nanoparticle supported on γ-Al2O3 catalyst bed. After purging their catalyst of H2O and CO2, ammonia and oxygen were added to the reaction vessel where ammonia was adsorbed onto the catalytic surface, resulting in an increase in temperature. This increase in temperature catalyzed the oxidative decomposition of ammonia, an exothermic process. This heated up the reaction, which in turn, provided the energy for the endothermic decomposition of ammonia into hydrogen and nitrogen. The catalyst pre-treatment did require heating to remove water and carbon dioxide, but it did not require subsequent re-heating. Tests on catalyst cycling showed that after the initial pre-treatment of the RuO2/γ-Al2O3 catalyst with helium at 300oC, the catalyst was able to cycle three times and still produce hydrogen in maximum yields. Furthermore, these studies included oxidative passivation to ensure that no heat was produced from oxidation of Ru to RuO2. In practice, oxidative passivation will not be necessary. So, even though heating is required to pre-treat the catalyst, heating is not required for additional cycles of the catalyst.In an effort to understand how the RuO2/γ-Al2O3 catalyst works, Nagaoka et al. compared the maximum catalytic bed temperature that results from self-heating of RuO2/ γ-Al2O3 to RuO2/La2O3, a known ammonia decomposition catalyst. They found that the aluminum-based catalyst heated to a maximum temperature of 97oC, while the lanthanum-based catalyst heated to a maximum temperature of 53oC. This is important because the auto-ignition temperature for the oxidative combustion of ammonia is 90oC, and it explains why better reaction yields were seen with RuO2/ γ-Al2O3. The authors point out that this difference in adsorption temperature is likely due to the favorable interaction between ammonia, a basic molecule, and Al2O3, which is a Lewis acid. La2O3, on the other hand, is a Lewis base.Additionally, the authors looked at the difference between using bare γ-Al2O3 as a catalyst and RuO2/ γ-Al2O3. They found that 90% of the ammonia adsorbs onto bare γ-Al2O3 compared to the catalyst bed and the RuO2 nanoparticle. This implies that ammonia is chemisorbed onto the nanoparticle and γ-Al2O3, which then promotes multilayer physisorption. Overall, this type of catalyst is helpful in providing enough heat to overcome the needed heat requirements for the endothermic decomposition of ammonia into hydrogen and nitrogen gas. This study shows that self-heating catalysis is a viable option for exploring solutions to the practical difficulties in using ammonia as a hydrogen fuel source. (Phys.org)—Hydrogen has the potential to provide an alternative, clean energy source, particularly as applied to fuel cell technology. Current fuel sources involve carbon-containing fossil fuels or carbon-containing organic molecules, which result in the production of excess CO2, a greenhouse gas. Several initiatives, including a national initiative in Japan, seek to create a low-carbon usage society by using alternative fuel sources.

DOI: 10.1126/sciadv.1602747AbstractAmmonia has been suggested as a carbon-free hydrogen source, but a convenient method for producing hydrogen from ammonia with rapid initiation has not been developed. Ideally, this method would require no external energy input. We demonstrate hydrogen production by exposing ammonia and O2 at room temperature to an acidic RuO2/γ-Al2O3 catalyst. Because adsorption of ammonia onto the catalyst is exothermic, the catalyst bed is rapidly heated to the catalytic ammonia autoignition temperature, and subsequent oxidative decomposition of ammonia produces hydrogen. A differential calorimeter combined with a volumetric gas adsorption analyzer revealed a large quantity of heat evolved both with chemisorption of ammonia onto RuO2 and acidic sites on the γ-Al2O3 and with physisorption of multiple ammonia molecules.

Krishnagar: Accusing the Centre of running parallel governments in states, Chief Minister Mamata Banerjee on Thursday announced that her government will withdraw from the Ayushman Bharat health insurance scheme.Addressing a gathering at Krishnagar Government College ground after giving away prizes to the winners of the first Jaltarang Sports festival, she said letters bearing the photograph of Prime Minister Narendra Modi along with health cards under Ayushman Bharat scheme were being sent to individuals. The logo embossed on the letter is a lotus which is also the official party symbol of the BJP. “This is cheating. Where is the budget to provide medical assistance to the beneficiaries,” she wondered and added: “The Centre collects various kinds of taxes from the states and gives back a percentage of the collected amount. Thus, the states have a share. But the BJP is projecting it in such a manner as if it is giving the medical assistance to them.” Also Read – 3 injured, flight, train services hit as rains lash BengalThe Chief Minister said under the Constitution, health, education and law and order are State subjects and she failed to understand why the Centre is intervening into the matter. “What does Modi think of himself? Is he trying to run parallel governments in the states? I will request all the states to intensify vigil and stop this nasty practice,” she said. Banerjee further added: “The new government in Delhi will ensure that the federal structure in our country is strengthened. ” Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedShe said in case of crop insurance of the farmers, the Centre gives only 20 percent of the premium and publishes the picture of the Prime Minister to give a message to the farmers as if the BJP is giving the money to them. “We have decided to pay the premium on our own and have paid Rs 625 crore in 2018. Everywhere the BJP is playing dirty politics to mislead people,” she maintained. Banerjee said 10 percent reservation for economically challenged general caste “is another big hoax. Modi is lying to the masses and whenever an election comes, the quantum of lies go up. Have you received Rs 15 lakh which he had announced before the 2014 election.” She alleged that Modi has destroyed the institutions like CBI, ED and even RBI. “He has a big mouth and talks a lot. He should buy two mirrors — one to see his face and the other to see him talking. Even when he gives speeches in English, they are manipulated. When we speak, we make mistakes but we never use technology to project ourselves as flamboyant orators.” Banerjee laid the foundation stone of Kanyashree University and said a country can make progress if girls are looked after properly. She added that Kanyashree has helped girls to pursue higher education and a day will come when girls from Bengal will reach the top in every sphere of life.
3 min read Volkswagen is looking at on-demand mobility services such as smartphone ride-hailing to earn a “notable share” of future revenues as the carmaker pushes a strategic shift in the wake of its emissions scandal, its top executive said.Volkswagen, or VW, which posted 213 billion euros ($237.90 billion) of revenue last year, on Wednesday signed a cooperation with ride-hailing company Gett after announcing a $300 million investment in the firm last week.Cooperation with Gett may lead to business models involving car sharing, limousine rides and taxi services in the fast-growing ride-hailing market which in Europe alone may yield 10 billion euros of sales by 2025 and could grow more than 30 percent annually, VW Chief Executive Matthias Mueller said.”In future, our core product will not be just the car,” Mueller said. “Our core product, our promise to customers, is mobility.”Europe’s largest automaker will this month unveil a new business strategy aimed at improving accountability and speeding up model development, with greater investments in electric cars, new technologies and mobility services among the key elements, company sources have said.But VW’s rivals are not standing idly by. Toyota Motor Corp. last week said it would invest in mobility company Uber Technologies Inc. while General Motors invested $500 million in Lyft, Uber’s main U.S. rival.The growing number of deals reflects the desire by automakers to avoid becoming bystanders if a significant number of consumers around the world choose to forego vehicle ownership and buy transportation by the mile or the minute.”Through this partnership, we’re getting access to 100 million VW customers,” Gett founder and chief executive Shahar Weiser said. Volkswagen and Gett declined to disclose the financial terms of their agreement.Wolfsburg-based VW has long ignored alternative mobility concepts unlike its German rivals Daimler and BMW who have for years been running their own car-sharing operations.The advent of smartphones has fundamentally changed customer expectations, with travelers seeking to connect to different modes of transportation through apps.CEO Mueller on Wednesday pledged that post-dieselgate VW will open up to new investments and partnerships such as with Gett.”Volkswagen now is not the same as Volkswagen before I became CEO” in September 2015, Mueller said, indicating the group is willing to expand beyond manufacturing and selling cars as a means to broaden its appeal with customers.”The times when we thought that the world revolves around Wolfsburg are history.”(Reporting by Andreas Cremer; Editing by David Gregorio) June 2, 2016 This hands-on workshop will give you the tools to authentically connect with an increasingly skeptical online audience.
