Fixing Perovskite Film Cracks Made Easy
March 18, 2020 | Leave a Comment
A new Brown University study found that cracks in brittle perovskite films can be easily healed with compression or mild heating. This is a good sign for the use of perovskites in next-generation solar cells. The study, published in the journal Acta Materialia, found that though perovskite films tend to crack easily, those cracks are […]

Making Methane From CO2 With Electricity
March 17, 2020 | Leave a Comment
Waseda University scientists of Japan have developed a new method to convert carbon dioxide to methane with an electric field at low temperatures. Compared to previous methods, this new method can produce any amount of methane whenever necessary. Methane, the main component of natural gas can be used to generate heat and electricity, so this […]

Laser Etch a Perfect Radiant Energy Absorber
March 12, 2020 | Leave a Comment
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 […]

Two Major Improvements to Potassium Batteries
March 11, 2020 | Leave a Comment
First to get out a press release was Australian scientists who have developed a nonflammable electrolyte for potassium and potassium-ion batteries. Then a couple weeks later researchers at Rensselaer Polytechnic demonstrated how they can overcome a persistent challenge known as dendrites to create a potassium metal battery that performs nearly as well as a lithium-ion […]

Blue Green Algae Now Produce Oil From Water
March 10, 2020 | Leave a Comment
Open Image…Save ImageOpen Image (using #TmpD/ia)… University of Bonn now have shown cyanobacteria – colloquially called blue-green algae – can produce oil from water and carbon dioxide with the help of light. The result is unexpected. Until now, it was believed that this ability was limited to plants. Now its possible that blue-green algae will also become interesting as suppliers […]
