A team of scientists say they’ve found a way to make a battery cathode with a hierarchical structure where the reactive material is abundant yet protected — key points for high capacity and long battery life.
A proposed recovery technique for oil extraction not only outperforms existing drilling and recovery techniques, but also has the potential to sequester more carbon dioxide in the process.
Kate YoderWhen it comes to creating robots that look like humans, we’re getting good — uncannily good. And one expert has claimed that in 15 years, they’ll be smarter than us, too. But until recently, we haven’t devoted much thought to the robotic afterlife. Where, exactly, does a robot go when it has outlived its usefulness? Most robots are made from metal and plastic — and I’d hazard a guess that your out-of-commission Roomba isn’t headed to the compost pile. But in the future, it looks like our artificial friends could be going six feet under along with the rest of us. A team of scientists from the Italian Institute of Technology (IIT) are on a mission to engineer completely biodegradable robots. Their…
The first lithium-ion battery has been developed that shuts down before overheating, then restarts immediately when the temperature cools. The new technology could prevent the kind of fires that have prompted recalls and bans on a wide range of battery-powered devices, from computers to hoverboards.
Some of the natural gas harvested by hydraulic fracturing operations may be of biological origin — made by microorganisms inadvertently injected into shale by oil and gas companies during the hydraulic fracturing process, a new study has found.
Will the Tour de France prologue in Utrecht get the winner it deserves? New aerodynamic research shows that riders in a time trial can save vital seconds by riding closer to the following team car. Over a short distance like the prologue of the Tour de France, that can save as much as 6 seconds: enough to make the difference between winning and losing.
adminEngineers have identified a new approach for the storage of concentrated solar thermal energy, to reduce its cost and make it more practical for wider use.
