Scientists are rethinking how to detect alien life by focusing on planets vastly different from Earth. Instead of searching for familiar biosignatures like oxygen, they’re investigating methyl halides ...

The study builds on previous research investigating different biosignature gases, including dimethyl sulfide, another potential sign of life. However, methyl halides appear particularly promising ...

x Addition reactions involving a hydrogen halide (hydrohalogenation) Hydrohalogenation is an addition reaction in which a hydrogen halide, such as HCl or HBr, is added to an alkene. This process ...

The Food and Drug Administration considers hydrogen-infused water to be “generally recognized as safe,” as long as the hydrogen molecules make up no more than 2.14 percent of the drink.

If realized using solar energy or other renewable energy, water splitting could be a promising way of sustainably producing hydrogen (H2) on a large-scale. Most photoelectrochemical water splitting ...

A research team has developed OHP-based photoanodes for photoelectrochemical (PEC) water splitting, minimizing the usual limitations. Meanwhile, China released its first hydrogen guideline, and ...

Researchers from Korea and USA have developed highly efficient photoanodes that suppress undesirable losses associated with photoelectrochemical water splitting for hydrogen production and enhances ...

Organometal halide perovskites (OHPs) have the potential to be used as photoanodes in photoelectrochemical water splitting to produce hydrogen.
