ChemPhysChem - FSRS Review

posted May 15, 2016, 11:39 AM by David Wartmann   [ updated May 15, 2016, 11:42 AM ]

Femtosecond stimulated Raman spectroscopy (FSRS) is an ultrafast nonlinear optical technique that provides vibrational structural information with high temporal (sub-50 fs) precision and high spectral (10 cm−1) resolution. Since the first full demonstration of its capabilities ≈ 15 years ago, FSRS has evolved into a mature technique, giving deep insights into chemical and biochemical reaction dynamics that would be inaccessible with any other technique. It is now being routinely applied to virtually all possible photochemical reactions and systems spanning from single molecules in solution to thin films, bulk crystals and macromolecular proteins. This review starts with an historic overview and discusses the theoretical and experimental concepts behind this technology. Emphasis is put on the current state-of-the-art experimental realization and several variations of FSRS that have been developed. The unique capabilities of FSRS are illustrated through a comprehensive presentation of experiments to date followed by prospects.

Rapid fabrication of nickel molds for prototyping embossed plastic microfluidic devices

posted Sep 16, 2013, 3:46 AM by Richard Novak

We have developed a way to very quickly prototype microfluidic devices in plastic, rather than the usual PDMS.  The goal is to be able to work with a wide range of materials with properties tailored to the application and to develop new designs efficiently.  Read the paper
