Water into fuel: The new nanomaterial that could upgrade green hydrogen

Generating hydrogen without releasing carbon dioxide sounds simple: pass electricity through water, split water molecules and generate green hydrogen. The hard part is the electrocatalyst. The best ones rely on platinum, ruthenium and iridium, which are scarce and expensive.
We wanted to know whether a small amount of iron and nickel oxides, anchored on carbon nanofibers grown by chemical vapor deposition the right way on the right scaffold, could do the job instead. Our results are published in ACS Applied Nano Materials.

Shared aquifers, border hotspots: Cooperation should follow where groundwater is pumped, scientists say
Groundwater depletion and groundwater-dependent irrigation tend to concentrate close to international borders within aquifers shared by two or more countries, where pumping on one side is more likely to affect users on the other, according to a publication by the United Nations U

Keeping water molecules connected reduces carbon electrode corrosion
Carbon is inexpensive, conductive, and widely used in technologies such as fuel cells and water electrolyzers. But under strongly oxidizing conditions, carbon electrodes gradually corrode.

Alaska’s monster tsunami sent water 1,580 feet up a mountain
A massive landslide in Alaska triggered the second-highest tsunami ever recorded, sending water and debris 1,580 feet up a mountainside just hours after tourists visited the area. Scientists discovered that the disaster was preceded by several warning signs, including rapid glaci
