Nevertheless, Beijing appears... Читать дальше...

Washington University in St. Louis scientists have developed a novel material that supercharges innovation in electrostatic energy storage. The material is built from artificial heterostructures made of freestanding 2D and 3D membranes that have an energy density up to 19 times higher than commercially available capacitors. Electrostatic capacitors play a crucial role in modern electronics. They enable ultrafast charging and discharging, providing energy storage and power for devices ranging from smartphones...

The renewable revolution will rely on a whole lot of non-renewable resources to get the job done. Building out the massive amount of clean energy infrastructure needed for a global decarbonization transition is going to require huge quantities of resources. In particular, the clean energy transition is going to call for a whole lot of specialty metals and minerals used for different green technologies such as solar panels, batteries, wind turbines, and electrical wiring. Indeed, metals currently... Читать дальше...

The UN is this week discussing the future of plastic—or so it would seem on the surface. The UN Global Plastics Treaty negotiations aim to curb plastic pollution by essentially curbing the use of plastics globally. And they look set to fail. The goal is certainly noble. Reducing the massive amount of plastic waste that we produce on a daily basis to keep it from ending up in rivers, oceans and, according to some researchers, our bodies. Achieving this goal, however, is quite another matter. Plastics... Читать дальше...

For decades, when people discussed space travel they thought of NASA. After all, the National Aeronautics and Space Administration accomplished the first moon landing in 1969 and has achieved many more feats since. However, over the last few years, several billionaires have been investing in space travel in a bid to offer passenger flights to space and enhance satellite technology. But where can these billionaires’ ventures take us and what does it mean for just a few players to be holding so much power? Читать дальше...
