Probing weak hydrogen bonds with Time-Resolved Spectroscopy

Probing weak hydrogen bonds with Time-Resolved SpectroscopWeak hydrogen bonds between the highly polarized hydrogen atom of chloroform and the amide carbonyl were proved and probed via linear and nonlinear IR spectroscopic techniques. Experiments showed that weak hydrogen bonds have an energetics of few kcal/mol and are responsible for distinguishable arrangements of chloroform molecules around carbonyl groups.

Thermal and chemical effects of fillers on free-radical frontal polymerization

thermal and chemical effects on free-radical frontal polymerization

Filled systems are important for the development of materials through frontal polymerization. Fillers are added to control the rheological properties of the formulation and to enhance the mechanical properties of products. Results demonstrate that some fillers can increase front velocity through their high thermal diffusivities while others decrease it by acting as radical scavengers.

 Utilizing Engineered Soil Surrogates to Study Environmental, Ecological, and Agricultural Processes

Engineered soil depicting structure with sorption studiesA novel model approach was developed and applied to gain a molecular-level understanding of environmental pollutant/soil interactions. The approach provides a scalable platform with molecular-level control of the soil organic matter (SOM) chemical composition and structure, allowing one to examine proposed SOM interactions with agricultural chemicals and beyond.

Reducing Toxic Hexavalent Chromium for Clean Water

Light spectrum of hexavalent chromium for noble metal free, clean water

Highly toxic Cr(VI) can be reduced to benign Cr(III) in water on unmodified and inexpensive carbon electrodes. The slow step over a wide range of pH is identified, which will help develop new energy-efficient water purification technologies.
