Djakadam suffers cut in Cheltenham fall

first_img Willie Mullins’ charge was sent off the 5-6 favourite for the Grade Two event in what was supposed to be his prep run for the Timico Cheltenham Gold Cup at the Festival in March. He was still travelling well when he crashed out at the 10th fence, suffering a cut that required stitching in the process. Djakadam is set for a week on the easy list after sustaining a cut on his chest when falling at Cheltenham on Saturday. Mullins tweeted: “Djakadam is back home. He has a cut on his chest that required stitching and will have an easy week walking.” center_img Press Associationlast_img read more

O’Shea pays tribute as he exits manager role

first_imgHe also paid tribute to the players and their families and said he was in no doubt that the future of Tipp hurling is bright with the current crop of players. The Cloughjordan native has stepped down from the manager’s post following the Premier’s exit from this year’s All Ireland championship. Selector Michael Ryan is set to take up the mantle. Speaking on Extra Time here on Tipp FM last night, O’Shea had a special word of thanks for the Tipperary GAA fans. last_img

Samsungs Graphene Ball Battery Promises Higher Capacity Faster Charging

first_img Additive Breakthrough Makes EV Batteries Suck Less in the ColdThe Battery in This Phone is Five Times Bigger Than Yours Stay on target Let us know what you like about Geek by taking our survey.center_img Researchers at the Samsung Advanced Institute of Technology (SAIT) developed a next-gen battery technology they call a “graphene ball.”A sheet of carbon atoms arranged in a hexagonal lattice, graphene is the basic structural element of other forms of carbon, including graphite and charcoal.The much-talked-about allotrope has gained attention among battery manufacturers, excited about its top-notch physical and chemical stability: Graphene is 100 times more effective than copper in conducting electricity, and boasts electron mobility 140 times faster than silicon—making it “an ideal material” for fast charging, according to Samsung.AdChoices广告It also blows standard lithium-ion batteries out of the water.Which is good news for mobile device and electric vehicles owners (i.e. basically everyone).For more than 25 years, most household electronics have run on lithium-ion batteries. But, as most people know, the technology requires at least an hour to recharge fully, and has little room for improvement.Many believe its successor will come in the form of graphene, a material with high strength and conductivity to batteries. In this case, a ball of it.Samsung claims its orb (described as a “3D popcorn-like structure”) requires only 12 minutes to juice up, and can maintain a stable 60℃ temperature—key for electric vehicles (and Galaxy Note handsets).“Our research enables mass synthesis of multifunctional composite material graphene at an affordable price,” project leader Son In-hyuk said in a statement. “At the same time, we were able to considerably enhance the capabilities of lithium-ion batteries in an environment where the markets for mobile devices and electric vehicles [are] growing rapidly.”Results of SAIT’s study—conducted in collaboration with Samsung SDI and a team from Seoul National University’s School of Chemical and Biological Engineering—were recently published in the journal Nature Communications.The Institute has also filed two applications for the “graphene ball” technology patent in the US and Korea.“Our commitment is to continuously explore and develop secondary battery technology in light of these trends,” Son said.last_img read more
