In chemistry of inorganic crystals, the octacalcium phosphate (OCP) is an apatite based crystals and having a hydrated layers which used in producing needle or plate-shaped hydroxyapatite (HAP) nanocrystals. Although, prepared by dissolution precipitation reaction. These reaction led to hexagonal HAP nanocrystals formation under hydrothermal condition from OCP at 180 for 3 hours with pH solutio...

Manuscript by Alyson Baergen and D. J. Donaldson focuses on formation of HONO, a key chemical species and/or reaction intermediate in atmospheric chemistry, during photolysis of urban grime. Given the fact that sources and formation of daytime HONO in urban setup are poorly understood, this study reveals potential chemical and photochemical reaction pathways and mechanisms to yield HONO. The kn...

Conducting mesoporous TiO2 is rapidly gaining importance for green energy applications. To optimise performance, its porosity and crystallinity must be carefully fine-tuned. To this end, we have performed a detailed study on the temperature dependence of TiO2 crystallisation in mesoporous films. Crystal nucleation and growth of initially amorphous TiO2 derived by hydrolytic sol-gel chemistry is...

Our research is in the area of solid-state organic chemistry, which lies at the interface between physical organic chemistry and materials science. We use crystalline solids as models to probe fundamental issues about physical processes, molecular interactions and chemical reactions that are important for fabrication, stabilization and application of technological materials. Much of our most re...
