Berkeley Lab nanoscale imaging study yields key insights into photo-electrochemical water splitting

Green Car Congress

In the quest to realize artificial photosynthesis to convert sunlight, water, and carbon dioxide into fuel—just as plants do—researchers need to not only identify materials to efficiently perform photoelectrochemical water splitting, but also to understand why a certain material may or may not work. —Johanna Eichhorn.

New photochemical diode artificial photosynthesis system doubles efficiency of solar water splitting

Green Car Congress

Researchers in Canada have demonstrated a new photochemical diode artificial photosynthesis system that can enable efficient, unassisted overall pure water splitting without using any sacrificial reagent. overall water splitting reaction. These free charges split water molecules into hydrogen and oxygen. … in neutral (pH?~?7.0)

NUS-led research team develops cost-effective technique for mass production of high-quality graphene; 50x less solvent

Green Car Congress

Preparation of ultra-high concentration graphene in water. b) New non-dispersion strategy for graphene production in water. Pretreated graphite is exfoliated by high-rate shearing and subsequently flocculated in alkaline water, producing graphene slurry on a large scale (100? g), high yield (82.5?wt%),

Researchers take first 3D images of microscopic hydrogen-embrittled cracks in metal

Green Car Congress

Microfractures in metal alloys, though impossible to see with the naked eye, can easily spread when exposed to water or hydrogen and lead to major problems in structures such as bridges, electrochemical and nuclear plants and hydrogen storage containers, leading to failures and expensive repairs.

Biofuels- paving the way for low carbon future in mobility – ET Auto

Baua Electric

Given its key role in the Indian biofuel program, ethanol will be the focus of this article. Third generation ethanol utilizes algae for producing ethanol from waste water (3G), while fourth generation ethanol is an amalgamation of genomically prepared microorganisms and genetically prepared algae (4g).
