New 'molecular movie' reveals ultrafast chemistry in motion

X-ray laser measures atomic-scale details of how ring-shaped gas molecule breaks open, unravels

23-Jun-2015

Scientists for the first time tracked ultrafast structural changes, captured in quadrillionths-of-a-second steps, as ring-shaped gas molecules burst open and unraveled. Ring-shaped molecules are abundant in biochemistry and also form the basis for many drug compounds. The study points the way to ...

Renewable energy from evaporating water

New clean energy source produces electricity, could power robots, sensors and vehicles

18-Jun-2015

An immensely powerful yet invisible force pulls water from the earth to the top of the tallest redwood and delivers snow to the tops of the Himalayas. Yet despite the power of evaporating water, its potential to propel self-sufficient devices or produce electricity has remained largely untapped - ...
