Application

Precursor for rive-coordinate, heteroleptic thoilate/N complexes which are petential models for cysteine-ligated metalloenzyme activity.
The vapor-phase co-reductions with other metal halides by hydrogen results in finely divided intermetallics with applications as structural materials or compounds with useful thermoelectric, magnetic, and oxidation-resistance properties.

Nanostructured Materials Through Ultrasonic Spray Pyrolysis

Advances in materials have often been led by the development of new synthetic methods that provide control over size, morphology and structure. The preparation of materials in a scalable and continuous manner is critical when development moves beyond lab-scale quantities.

Thermoelectric Performance of Perovskite-type Oxide Materials

The prevailing strategies for heat and electric-power production that rely on fossil and fission fuels are having a negative impact on the environment and on our living conditions.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
