Tungsten oxide hydrate: the future of smart windows ( interestingengineering.com )

ABSTRACT: The independent modulation of visible and near-infrared light by a single material, termed dual-band electrochromism, is highly desirable for smart windows to enhance the energy efficiency of buildings. Tungsten oxides are commercially important electrochromic materials, exhibiting reversible visible and near-infrared...

Harvesting almost-unlimited energy (in tiny amounts) from ripples in graphene ( interestingengineering.com )

Scientists have figured out how to harness Brownian motion -- literally the thermal energy of individual molecules -- to make electricity, by cleverly connecting diodes up to pieces of graphene, which are atom-thick sheets of Carbon. The team has successfully demonstrated their theory (which was previously thought to be...
