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 studies

A 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.

Photopolymerization of Monomer-Containing Deep Eutectic Solvents

Log−Log plot graphic of initial rate versus light intensity of deep eutectic solvent (DES) monomers photopolymerization

The kinetics of photopolymerization in deep eutectic solvents (DESs) is investigated through RT‐FTIR. The systems of this study are choline chloride DESs made of acrylic acid and methacrylic acid (DES monomers) and a nonreactive analog isobutyric acid. Analysis of the evolution of conversion indicates dramatic increase in polymerization rate when comparing the polymerization of the DES monomers to pure monomer polymerization.
