Sun-free photovoltaics
(Nanowerk News) A new photovoltaic energy-conversion system developed at MIT can be powered solely by heat, generating electricity with no sunlight at all. While the principle involved is not new, a novel way of engineering the surface of a material to convert heat into precisely tuned wavelengths of light — selected to match the wavelengths that photovoltaic cells can best convert to electricity
Nanoengineered graphene coating harvests energy from flowing water
Nanoengineered graphene coating harvests energy from flowing water (Nanowerk News) Researchers at Rensselaer Polytechnic Institute have developed a new method to harvest energy from flowing water. This discovery aims to hasten the creation of self-powered microsensors for more accurate and cost-efficient oil exploration. Led by Rensselaer Professor Nikhil Koratkar, the researchers investigated how
Graphene: Foaming for stretchable electronics
(Nanowerk News) Graphene's remarkable conductivity, strength and elasticity has made it a promising choice for stretchable electronics — a technology that aims to produce circuits on flexible plastic substrates for applications like bendable solar cells or robotic-like artificial skin. However, integrating the polymers needed for such applications with typical chemically derived graphene results i
