Making methane from CO2: Carbon capture grows more affordable
In their ongoing effort to make carbon capture more affordable, researchers at the Department of Energy’s Pacific Northwest National Laboratory have developed a method to convert captured carbon dioxide (CO2) into methane, the primary component of natural gas.
By streamlining a longstandin ... more
It's elemental: Ultra-trace detector tests gold purity
Unless radon gas is discovered in a home inspection, most people remain blissfully unaware that rocks like granite, metal ores, and some soils contain naturally occurring sources of radiation. In most cases, low levels of radiation are not a health concern. But some scientists and engineers ... 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
