A team of researchers made a decisive step towards a redox-flow battery which is simple to handle, safe and economical at the same time: They developed a system on the basis of organic polymers and a harmless saline solution. The new redox-flow battery can withstand up to 10,000 charging cycles without losing a crucial amount of capacity.
adminResearchers have succeeded in visualizing changes in defect density on the surface of GaN through the laser terahertz emission microscope (LTEM) which measures THz waves generated by laser emission. The discovery shows that LTEM is useful as a new method for evaluating the quality of wide-gap semiconductors and it is also expected that LTEM will bring a breakthrough in the development of next-generation optical devices, super high frequency devices, and energy devices.
Physicists have developed a method to synthesize a unique and novel type of material which resembles a graphene nanoribbon but in molecular form. This material could be important for the further development of organic solar cells.
Katie HerzogFor 23 years, David Koch, the billionaire industrialist who made a fortune off fossil fuels, ranching, fertilizers, and other environmental nightmares, has served on the board at the American Museum of Natural History. Koch’s position on the board is controversial, not least because of his position on climate change: The Koch family has spent millions funding climate change denier groups and disinformation campaigns, and scientists around the country have called for Koch to be removed from the museum board. Well, they finally got what they wanted — the American Museum of Natural History announced Koch’s resignation this week. A museum spokeswoman said Koch’s departure is unrelated to the calls for his dismissal, but, as The New York Times reports, a letter sent to museums of…
