Molecules containing noble gases shouldn’t exist. By definition, these chemical elements — helium, neon, argon, krypton, xenon and radon — are the party poopers of the periodic table, huddling in the ...

Though most human noses can detect suspicious smells at relatively high levels, they're not always able to discern every ...

Many molecules assemble into crystalline or disordered glassy structures on surface. With certain assembly approaches, specific molecules can be made to form ordered yet aperiodic structures, such as ...

Tiny concentrations Qizhong Liang in Jun Ye's lab at JILA on the campus of the University Colorado Boulder. Liang and colleagues have developed a new technique for measuring trace concentrations of ...

Note: This video is designed to help the teacher better understand the lesson and is NOT intended to be shown to students. It includes observations and conclusions that students are meant to make on ...

A group of researchers have created an unusual material -- a soft crystal made of molecules known as a catenanes-- that behaves in a novel way that could be used in applications such as films that ...

Emerging experimental techniques combined with theoretical advances allow unprecedented studies of the dynamics of gas phase molecules and clusters induced in interactions with photons, electrons, or ...

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

This study presents the development and characterization of a nanomechanical gas sensor array with piezoresistive detectors for a wide range of applications. The sensors, made of silicon and polymers ...
