Recently, Tevis D. B. Jacobs and colleagues have shown how silicon- and oxygen-containing hydrogenated amorphous carbon (a-C:H:Si:O) coating enhance the thermal stability in vacuum, but tremendously increases the thermo-oxidative stability and the resistance to degradation upon exposure to the harsh conditions of low Earth orbit (LEO). These findings provide a novel physically-based understanding of the superior stability of a-C:H:Si:O in harsh environments compared to a-C:H.

The Earle K. Plyler Prize for Molecular Spectroscopy and Dynamics recognizes and encourages notable contributions to the field of molecular spectroscopy and dynamics. The prize consists of $10,000, an allowance for travel expenses, up to $1000, to attend the meeting at which the prize is to be presented and a certificate citing the contributions made by the recipient. The recipient is invited to contribute a perspective article to the Journal of Chemical Physics. It is presented annually.
"Scanning near-field optical microscopy combined with pump–probe spectroscopy can resolve ultrafast dynamics at the nanoscale."
In this short article, Hrvoje Petek reflects on a new technique that combines the nanometre resolution of near-field microscopy with the femtosecond resolution of pump–probe spectroscopy. This technique has been developed by Markus Raschke and colleagues at the University of Colorado at Boulder and submitted in the present issue of Nature Nanotechnology.
