Compact batteries enhanced by spontaneous silver matrix formations

Posted: 08 Jan 2015 11:13 AM PST

A conductive silver matrix forming inside an otherwise poorly performing battery enhances its efficiency and potential applications. X-rays revealed where, when, and how these nanoscale "bridges" emerge.

Emissions-free cars get closer

Posted: 08 Jan 2015 09:59 AM PST

Hydrogen fuel cells -- possibly the best option for emission-free vehicles -- require costly platinum. Nickel and other metals work but aren't nearly as efficient. New findings help pin down the basic mechanisms of the fuel-cell reaction on platinum, which will help researchers create alternative electrocatalysts.

Preventing transformer explosions

Posted: 08 Jan 2015 06:20 AM PST

Technology used in the crumple zones of cars can avert serious explosions in transformers, believe researchers. Large oil filled transformers are found in all power and switching stations, as well as in many large buildings. If an internal short-circuit occurs, an electrical arc, gas formation and pressure increase will be the result.
