What we flush can be converted into a biocrude oil with properties very similar to fossil fuels. Pacific Northwest National Laboratory researchers have worked out a process that does not require that sewage be dried before transforming it under heat and pressure to biocrude. Metro Vancouver in Canada hopes to build a demonstration plant.
Pulling Apart Titanium Oxide Surfaces
Researchers slowly pull apart tiny bits of a titanium oxide mineral called rutile. The red dots near the top show the starting point. As the bottom half is pulled down, the top half stays attached by van der Waals forces -- until, that is, the pull becomes too great. The tips are about a th ... more
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
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
