From the Toilet to the Tank – Biofuels from Sewage

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

    A leap in using silicon for battery anodes

    The same material you'll find at the tip of a pencil--graphite--has long been a key component in today's lithium-ion batteries. As our reliance on these batteries increases, however, graphite-based electrodes are due for an upgrade. For that, scientists are looking to the element at the hea ... more

    Army scientists look inside batteries with a molecular eye

    Scientists are closer to understanding exactly what happens inside batteries that make them prone to fire, thanks to a molecular eye of sorts. Scientists at the U.S. Army Combat Capabilities Development Command's Army Research Laboratory teamed with researchers from the U.S. Department of E ... more

    Scientists learn more about the first hours of a lithium-ion battery's life

    The first hours of a lithium-ion battery's life largely determine just how well it will perform. In those moments, a set of molecules self-assembles into a structure inside the battery that will affect the battery for years to come. This component, known as the solid-electrolyte interphase ... more
