New twists (and bends) in LCD research

20-Apr-2016

Liquid crystals, discovered more than 125 years ago, are at work behind the screens of TV and computer monitors, clocks, watches and most other electronics displays, and scientists are still discovering new twists--and bends--in their molecular makeup. Liquid crystals are an exotic state of ...

Metal foam handles heat better than steel

01-Apr-2016

A new study from North Carolina State University researchers finds that novel light-weight composite metal foams (CMFs) are significantly more effective at insulating against high heat than the conventional base metals and alloys that they're made of, such as steel. The finding means the CMF is ...
