Is Webb at its final temperature?

The Mid-Infrared Instrument (MIRI) on NASA's James Webb Space Telescope is now cooled by a gaseous helium cryocooler to under 7 Kelvin. With the cooler in its final state, the Webb team is operating the MIRI instrument this ...

Engineering 2D semiconductors with built-in memory functions

A team of researchers at The University of Manchester's National Graphene Institute (NGI) and the National Physical Laboratory (NPL) has demonstrated that slightly twisted 2D transition metal dichalcogenides (TMDs) display ...

Cu interface matters during CO2 electroreduction

It is attractive to convert CO2 into multicarbon hydrocarbons and oxygenates (C2+ products), but it is challenging to enhance the kinetics of carbon-carbon (C-C) coupling during CO2 reduction reaction (CO2RR).

Activated carbon increases cryocooler efficiency

Cryocoolers are ultracold refrigeration units used in surgery and drug development, semiconductor fabrication, and spacecraft. They can be tubes, pumps, tabletop sizes, or larger refrigerator systems.
