Resonance Raman and Photoluminescence Spectroscopy and Imaging of Few-Layer MoS2
David Tuschel
Two-dimensional crystals like graphene are gaining attention because of the special electronic, optical, and optoelectronic properties of their monolayer and few-layer forms. There is now a great need for methods to characterize these materials, because of their experimental nature and structural variability, often within one film. Here, we explore the techniques to examine the spatial variation of the solid-state structure and electronic character of few-layer MoS2 flakes.

Determining Elemental Impurities in Pharmaceutical Materials: How to Choose the Right Technique
Robert Thomas
Although implementation of the new United States Pharmacopeia chapters <232> and <233> on elemental impurities has been delayed, pharmaceutical analysts should start planning now to meet the new requirements. This comparison of the capabilities of four major atomic spectroscopy techniques — FAA, ETA, ICP-OES, and ICP-MS — will help you choose the most appropriate analytical technique to meet the requirements of the new USP chapters as well as those of other analytical problems you are asked to solve.

2015 Salary Survey: Modest Gains, but Not for Everyone
Bethany Degg
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, and our survey results hint at additional underlying concerns.

On-Demand Webcast: Demystifying Interference Removal
Accurate and precise analysis is key to ensuring data quality and confidence in results. Interferences that normally arise can affect both accuracy and precision. During this web seminar, we will discuss interferences in ICP-OES and ICP-MS, focusing on potential sources of interference and their identification and removal by hardware or software techniques

Trends in Spectroscopy: A Big-Picture Look at Recent Innovations and Future Directions
Michael MacRae
How will spectroscopic measurement figure into big 21st-century efforts in science, technology, and engineering? How will advances in these fields change the rules of spectroscopic measurement in the future? With those questions in mind, we scanned the field of spectroscopy from a high altitude to identify some of the more noticeable shifts in the landscape of instruments and applications.
