Hydrogen provides a clean source of energy on demand…if you have the means to store such a volatile and reactive substance. Now researchers in Japan suggest they have hit on a game changing electrolyte for hydrogen batteries.

Hydrogen battery relieves the pressure for clean energy storage

Researchers develop an electrolyte that overcomes the low-capacity high-operating-temperature issues of previous hydrogen storage setups

A new book explores the link between film giant Kodak and the atomic bomb

How do you make a page turner out of industrial chemistry? One way is to mine the rich seam linking movies with weapons of mass destruction as @alicelovejoy.bsky.social demonstrates so successfully in Tales of Militant Chemistry.

In Tales of Militant Chemistry, Alice Lovejoy traces how film giants Kodak and Agfa helped produce weapons of war during the 20th century.

The chemistry of fear

Evidence found of nanocrystals lurking in low-density ‘amorphous’ ice

Evidence found of nanocrystals lurking in low-density ‘amorphous’ ice

Anna Demming @annademming.bsky.social · Jul 29

Thought the structure of ice was “crystal clear”? Most ice exists in space accumulating molecule by molecule where the temperatures are too low for the molecules to reorganise themselves. So outer space ice is amorphous? Wrong again...

Terahertz optoacoustics allows real-time monitoring of blood sodium levels – Physics World

Designer protein switches conformations like a natural one

Fungi are often described as the "dark matter" of the gut microbiome as they are hard to study. But it could be well worth the effort according to research led by Changtao Jiang at Peking University... www.livescience.com/health/truly...

Researchers shed light on the "dark matter" of the gut, revealing a species of fungus that could potentially help counter fatty liver disease. The research is in its early days, though.
