Rhgq Scientists Solve a 50-Year-Old Blood Group Mystery
A recent study from Penn Engineering researchers provides new insights into why silicon anodes in adidas samba donna lithium-ion batteries rapidly degrade and fail. Using advanced imaging techniques and high-contrast gold to stand in for silicon, they rsquo ve shown how pieces of the anode are trapped in the dunk panda chemical layer that forms in each cycle, gradually hollowing out the anode until it falls apart. Credit: Penn EngineeringRechargeable lithium-ion batteries are ubiquitous, powering smartphones, tablets, la ugg boots ptops and, increasingly, electric vehicles. Making these batteries lighter, smaller, cheaper and able to charge faster, all without sacrificing performance, is therefore a major design challenge. To tackle this problem, scientists and engineers are developing new electrode materials that can store greater amounts of lithium in the same amount of space.One promising solution is the use of alloy-type materials in a battery rsquo s negative electrode, also known as the anode. For example, one pound of Akmk Xiaomi retires MIUI to create a new interface, debuts on Xiaomi 14 series phones
Google self-driving cars to hit public roads in prototype testingSelf-driving cars from Google are taking another step closer to being a reality for the millions of drivers who brave urban gridlocks to work every day. Last September, Google was aw yeezys 350 arded multiple permits by the State of California to test its cards on public roads. But while t airmaxplus he search giant already has a fleet of modified Lexus RX450h h air max 1 ybrids on the road, Google has now announced that a few of its own prototype vehicles are finally making their way to Mountain View rsquo s roads for testing.Google rsquo s prototypes are slated to hit the roads this summer but the tests will take place on a rather cautious note ndash each prototype vehicle is capped at 25 mph (approximately 40km/h) and will have safety drivers on board at all times. The new prototypes will also use the same software used by the existing fleet of self-driving Lexus RX450h SUVs, which has logged almost a million autonomous miles so far.This means that th
