Core Technologies

All materials are ultimately based on molecules. We believe it is essential to focus on the molecular structure and intermolecular interactions within a material to design sustainable technologies, processes, and products.
Non-covalent Derivatization & Formulation Science Non-covalent Derivatization & Formulation Science
We are equipped to design, synthesize, and characterize small and medium scale multi-molecular solid-state systems. Our in-house expertise in developing structure-activity relationships of binary and ternary co-crystalline systems allows us to efficiently manipulate the bulk physical properties of materials while avoiding the use of high energies and hazardous reagents.

Metal Oxides Nanotechnology Metal Oxides Nanotechnology
We create technologies that allow for low energy processing of sol-gels and other dispersive states of metal oxides. These semiconductor/photo-active systems can be coated or incorporated into multi-component systems under ambient conditions while maximizing functional product properties.

Films, Coatings and Surfaces Films, Coatings and Surfaces
We have developed a number of new fundamental film forming and surface coating mechanisms that minimize energy utilization and VOCs. We have strong capabilities in microscopy and surface analysis which enable us to characterize and develop a wide variety of sustainable coating solutions.

Organic/Polymer Synthesis & Engineering Organic/Polymer Synthesis & Engineering
Because molecules form the foundational building blocks of all materials, it is essential that their synthesis be as sustainable as possible. We have deep expertise in the design, synthesis, and characterization of complex molecules using state of the art tools and methodologies. We also have specialized expertise in the functional polymeric materials. By creating co-polymeric systems with specific "built in" intermolecular interactions, we can control stability and reactivity while simultaneously providing unique properties.

Non Animal Toxicology Testing Non Animal Toxicology Testing
We develop toxicology screening technologies and new chemical sensors that avoid the use of hazardous materials and animal testing. We have in-house capability for evaluation of new and existing chemicals, materials, and formulations for both human and ecological toxicity. Bacteriological testing, cell based assays, human tissue models, and computational modeling are all used to investigate the safety of new and existing compounds.
