New record set for lowest temperature—38 picokelvins

A team of researchers affiliated with several institutions in Germany and two in France has set a new record for the lowest temperature ever recorded in a lab setting—38 picokelvins. In their paper published in the journal ...

'Double decoration' enhances industrial catalyst

Adding lead and calcium to an industrial catalyst dramatically improves its ability to support propylene production at very high temperatures, making it stable and active for a month.

Researchers reveal missing optical localized gap modes

Electromagnetically induced transparency (EIT) is a typical quantum destructive interference effect, which possesses many striking properties such as elimination of optical absorption, reduction of group velocity and remarkable ...

High pressure causes hydrogen variants to collapse

Hydrogen exists as a gaseous compound of two hydrogen atoms (H2). Under normal laboratory conditions, H2 occurs in the variants "ortho hydrogen" and "para hydrogen." Until now, it has been unclear how these variants behave ...

New tools 'turn on' quantum gases of ultracold molecules

JILA researchers have developed tools to "turn on" quantum gases of ultracold molecules, gaining control of long-distance molecular interactions for potential applications such as encoding data for quantum computing and simulations.

Methanethiol, a potential new feedstock in C1 chemistry

Catalytic conversion of molecules with one carbon atom such as methane, carbon dioxide (CO2), methanol (CH3OH) and others into higher-value chemicals is of major importance for a viable and sustainable chemical industry. ...
