University of Rochester researchers have demonstrated how laser etching of metallic surfaces creates the ”perfect solar energy absorber”. This not only enhances energy absorption from sunlight, but also reduces heat dissipation at other wavelengths. The researchers also demonstrated solar energy harnessing with a thermal electric generator. The University of Rochester research lab that recently used […]

The insightful and clever folks at UCLA have used a standard LightScribe DVD optical drive ($25+ and up at today) to produce a new type of capacitor electrodes that not only maintain high conductivity but also provide higher and more accessible surface area than conventional electrochemical capacitors (ECs) that use the typical activated carbon […]
