Nanomaterials Synthesis. The maturing grasps of the fabrication of the nanoscale semiconductor units now almost allows the realization of any semiconductor materials with any size, shape, and morphologies. We emphasize on green methods in making nanomaterials with minimal waste generation during the process and high activity for applications.

Microwave absorption. Microwave absorption is very important in many civil and military applications, such as information security, wireless communications, and object detection. Microwave absorption occurs if there is an effective resonance between the incident microwave electromagnetic field and the dipole rotations or magnetic resonance in the materials.

Solar Fuel Generation. Solar hydrogen generation is one of the keys step to achieve the dreamed sustainable hydrogen economy. In the photocatalysis, a photocatalyst is employed as the solar-to-fuel converter, and titanium dioxide, for example, is one of the most studied systems for this purpose. When the photocatalyst absorbs light with energy larger than the band gap, electrons and holes are generated in the conduction and valence bands, respectively. 

Solar Electricity Generation. Converting solar light direct to electricity has also been considered an essential pathway to energy sustainability. A photovoltaic device, or solar cell, converts absorbed photons directly into electrical charges that are used to energize an external circuit. Newer technologies besides silicon are of high interest.

Electrochemical Hydrogen Generation. Converting water into hydrogen and oxygen using electricity provides one short-term and large-scale solution to the clean hydrogen production. Developing earth-abundance, non-noble metal catalysts is critical to both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), and designing new electrolyzer systems is also important to lower the electrical energy to split water into hydrogen and oxygen.

Rechargeable Battery. The rechargeable lithium battery provides the portability of stored chemical energy with the ability to deliver this energy as electrical energy with a high conversion efficiency and no gaseous exhaust. The higher stored volume and gravimetric energy density of a Li ion battery has enabled realization of the cellular telephone and lap-top computer.

Environmental Pollution Removal. Titanium dioxide has been demonstrated as the most promising catalyst in environmental pollution removals. We will study the practical applications of new photocatalysts to remove bacteria and viruses in  wastewater or other conditions.

Solar Clean Building Technology. A realization of a self-cleaning green city dream can be practical when combining the photocatalytic removal capability in NOx, SO2, and organic pollutants under sun light irradiation with the self-cleaning function of the titanium dioxide coating on the outside of the buildings in the city a. In such a scenario, various organic pollutants and air pollution caused by road traffic and industry will be converted to non-toxic or washable compounds and be removed from the air and building surface, thus creating a clean city.
