Israeli scientists have developed a gas sensor that can distinguish “mirror image” molecules in the air, a breakthrough with the potential to revolutionize medical diagnostics, food and beverage ...

MIT researchers have developed a lightweight polymer film that is nearly impenetrable to gas molecules, raising the possibility that it could be used as a protective coating to prevent solar cells and ...

A research team has developed a small optical lens, only a few millimeters in size, whose refractive behavior changes in the presence of gas. This 'intelligent' behavior of the micro-lens is enabled ...

Three cheap hygroscopic salt solutions on carbon nanotube sensors distinguish nine toxic gases, including warfare agents, without engineered receptor molecules.

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 ...

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 ...

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 ...

Several factors, such as surface area, pore size distribution, temperature, pressure, and the nature of both the gas and porous material, influence the rate and extent of gas sorption. The size and ...
