A scientist wears a lab coat and gloves and adjusts scientific instrumentation in a laboratory. Researchers have developed a strong ultrathin polymer membrane that totally stops gas molecules from ...

Earth’s radiation can send some molecules spinning or vibrating, which is what makes them greenhouse gases. This infographic explains how relatively few heat-trapping molecules can have a planetary ...

Molecular cooling techniques face the hurdle of dissipating translational as well as internal energy in the presence of a rich electronic, vibrational, and rotational energy spectrum. In our ...

Maintaining gas stream humidity levels is critical in gas calibration, analysis, and calibration. Nafion-based gas humidification offers a sophisticated method for adding water vapor to gas flows, ...
