Ultrafast Laser Spectroscopy of Chemical Reactions

Ultrafast laser spectroscopy has extended reaction-dynamic studies into the dcosecond and femtosecond time domain. allowing for experimintal observations of transitory fragments that occur during collision or half-collision. This ability to observe molecular reactions allows real-time viewing of energy redistributions, measurements of state-to-state rates, and tests of microscopic statistical t...

Near infrared spectroscopy: a new tool for studying physical and chemical properties of polysaccharide gels

This study explored the use of short-wavelength near infrared spectroscopy (SW-NIR, 600–1100 nm) to characterize gellan gel, a polysaccharide gel. SW-NIR can classify commercial low acyl (LA) and high acyl (HA) gellan gel mixtures and predict the ratio of LA and HA gellan in a gel mixture (R 1⁄4 0:93; standard error of prediction 1⁄4 9.19%). In addition, SW-NIR methods can classify LA gellan ge...

Ultrafast laser-probing spectroscopy for studying molecular structure of protein aggregates.

We report the development of a new technique to screen protein aggregation based on laser-probing spectroscopy with sub-picosecond resolution. Protein aggregation is an important topic for materials science, fundamental biology as well as clinical studies in neurodegenerative diseases and translation studies in biomaterials engineering. However, techniques to study protein aggregation and assem...
