The future hydrogen economy may hinge on iridium, a metal so rare that only about 8 tonnes are produced worldwide each year.

When droplets containing non-volatile solutes dry on substrates, the fluid migrates outward via capillary force. Consequently, the solutes are carried to the periphery of the droplets and form “coffee ...

Perovskites are synthetic compounds that – in some ways – are a better alternative to the silicon semiconductors currently utilized in solar cells. And while there are still some hurdles to be crossed ...

Flame spray pyrolysis has long been used to make small particles that can be used as paint pigments. Now, researchers at Argonne National Laboratory are refining the process to make smaller, ...

A wide bristle brush creates more surface area than a round brush, which is better suited for details. What everyone knows from painting also applies to spraying PUR using the SCS process. However, ...

The latest short science news items from C&EN. Manufacturers make electrodes by coating metal foils with a slurry of a solvent and battery materials. Then they recover the solvent and dry the ...

Graphene has slowly made its way into sports gear, anticorrosion coatings, and even fabric face masks. But widespread use of the strong, conductive material in electronics, energy storage, and medical ...
