Expanding the temperature range of lithium-ion batteries
Electric cars struggle with extreme temperatures, mainly because of impacts on the electrolyte solutions in their lithium-ion batteries. Now, researchers have developed new electrolytes containing multiple additives that work better over a wide temperature range.
Lithium-ion batteries are w ... more
Rust never sleeps
Like iron flowing through the blood stream, iron minerals course through the ground. These minerals are used to make steel and other metal alloys used in everything from cell phone components and cars to buildings, industrial equipment and infrastructure.
Unfortunately, when exposed to oxyg ... more
Technology clears way for ethanol-derived jet fuel
ASTM International recently revised ASTM D7566 Annex A5 -- the Standard Specification for Aviation Turbine Fuel Containing Synthesized Hydrocarbons -- to add ethanol as an approved feedstock for producing alcohol-to-jet synthetic paraffinic kerosene (ATJ-SPK). The revision of ASTM D7566 Ann ... more
