batteriesToyota has reduced the rare earth materials used in electric vehicle magnets by 50%

No Comments
Toyota has developed the world’s first neodymium-reduced, heat-resistant magnet. Neodymium magnets are used in various types of motors such as the high-output motors found in electrified vehicles, use of which is expected to increase rapidly in the future. The new …

materialsOceanfloor mining for minerals towards the scale of ocean oil drilling

No Comments
Nextbigfuture wrote about Nautilus Minerals several times since 2010. Nautilus Mineral is scaling up ocean floor mining. In January 2016, Nautilus Minerals took delivery of the three Seafloor Production Tools (SPTs) from SMD. The SPTs were shipped to PNG in …

materialsNew Superhydrophobic/Superhydrophilic bandage material reduces blood loss by 60%

No Comments
Scientists at the Chinese Academy of Sciences have developed non-blood-absorbing hemostatic gauze after repeated experiments. Compared with traditional medical gauze, this new achievement can diminish blood loss by about 60 percent. They built a micro-nano structured layer in a surface …

chemistryToday GPUs for AI but then Phase Change Memory-Neuromorphic and then Quantum

No Comments
Today IBM is applying massively distributed deep learning algorithms to Graphics processing units (GPU) for high-speed data movement, to ultimately understand images and sound. The DDL algorithms “train” on visual and audio data, and the more GPUs should mean faster …

energyCommercial Perovskite solar cells at 10 cents per watt could soon bring lower cost energy

No Comments
The U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) has created an environmentally stable, high-efficiency perovskite solar cell, bringing the emerging technology a step closer to commercial deployment. Lower cost There are estimates that perovskite solar panels could cost …

materialsSuper-strong aluminum as strong as steel

No Comments
Researchers have demonstrated how to create a super-strong aluminum alloy that rivals the strength of stainless steel, an advance with potential industrial applications. “Most lightweight aluminum alloys are soft and have inherently low mechanical strength, which hinders more widespread industrial …

No Comments
Lightbridge is developing nuclear fuel with more surface area which can enable existing nuclear reactors to generate 10-40% more energy by changing the shape of the fuel. Enfission, is a new joint venture with Framatome to develop, license and sell …

airplaneLightweight alloy enables folding wings in flight for more fuel efficiency and performance

No Comments
NASA has successfully applied a new technology in flight that allows aircraft to fold their wings to different angles while in the air. The recent flight series, which took place at NASA’s Armstrong Flight Research Center in California, was part …

grapheneGraphene Nanoribbons are 100 times brighter than previous single molecule devices

No Comments
Researchers observed a bright and narrow band emission of red light from individual graphene nanoribbons, only 7-atom-wide, at a high intensity comparable to bright light-emitting devices made from carbon nanotubes. Optical emission was up to 10 million photons per second, …
