Spectroscopy

 Resonance and off-resonance Raman spectroscopy and imaging are used to examine the spatial variation of the solid-state structure and electronic character of few-layer MoS2 flakes. Simultaneous acquisition of photoluminescence spectra with the Raman scattering provides complementary ways of rendering Raman and photoluminescence spectral images of thin-film MoS2.

The latest Spectroscopy salary survey shows that the average salary has remained essentially static overall, which is welcome news after last year's drop. But not all sectors and groups are doing better.

This installment evaluates the application requirements for the determination of 15 elemental impurities in pharmaceutical materials as described in the new United States Pharmacopeia (USP) Chapters and and offers suggestions about which atomic spectroscopic technique might be the most suitable to use.

Recent federal science and technology initiatives are focusing public attention and funding on the need for innovative research in environmental quality, sustainability, medicine, and advanced materials.
