Overview Academic/Research Interest Areas

Dr. Gonsalves research focuses on the molecular design, synthesis, processing and characterization of novel materials.It draws on the fundamental knowledge of organic, inorganic/ organo-metallic chemistry for the synthesis of polymers and precursors for various materials. Self assembled nanostructures is a new focus of Dr. Gonsalves group, leading to novel sensors,structural including biomaterials as well as optical and magnetic materials.

Recent Projects and Results

Projects include the synthesis and processing of organo-metallic polymers as precursors for ceramics and intermetallics.

Reactive monomers and oligomers are being synthesized to produce high temperature coatings via thermal and/or laser techniques.

In an approach, biomimetic processing of novel ceramic/polymer composites is being pursued. Initial objectives included the adaptation of existing aqueous processing techniques for enabling the direct crystallization of inorganic phases on polymer matrices engineered as favorable substrates for heterogeneous nucleation and crystal growth.
