Recently, the understanding of nanotechnology has shown to play a transformative role in providing sustainable clean energy. In this context, we believe that the development of nanotechnological based research will provide technical challenges to meet the energy conversion, storage and conservation in affordable manner with control of nanomaterials, nanostructures and nanoscale phenomena. 

The super capacitor, photovoltaic, photochemical, hydrogen storage, thermal storage devices will be discussed which could provide the low cost efficient devices through the application of nanotechnology. The performance demand of super capacitor is improving by fabricating novel nanocomposite electrode by combining with processing techniques, geared towards high surface area and high metallic conductivity. Our graphite-conducting polymer or metal oxide electrodes have shown high power density cost effectively. Novel thermal energy storage materials with high rate heat capacity and compatible with any design are needed for military, commercial and solar energy applications. 

We are working on encapsulated Phase Change Material (PCM) for solar thermal energy applications. Recently, we have observed for the first time the photoelectrochemical properties of nanodiamond–ragioregular polyhexylthiophene conjugated polymer nanohybrid which is nearly 8 to 10 fold greater than most common metal oxide-conducting polymer hybrid materials. One of the biggest challenges for the commercial application of hydrogen-based energy is to find a high volumetric and gravimetric hydrogen storage capacity, the ability to be refueled quickly and repetitively and a safe transportation system. Out all the studied materials (metal hydride, carbon nanotubes, conducting polymer, etc.) have shown high hope, so emphasis is made to synthesize high surface area nanocomposite material for hydrogen storage applications.

The immunosensor can be used in clinical and medical diagnoses.It is vital to early diagnose cancer in order to improve the treatment for the patients. Nowadays, the need for reliable diagnosis tests has attracted the attention of many scientific societies in order to identify tumor markers in human serum.

Prostate specific antigen (PSA) is known as a valuable biomarker for the treatment of patients who suffer from prostate cancer. The aim of this research was to design and to produce a nanocomposite by using carbon nanotubes and ionic liquids in order to be used in the production of sensitive, repeatable, simple, and cost-effective immunosensors for the measurement of tumor markers, especially, PSA tumor marker.

Sandwich connection was used in this research in order to measure PSA. In this method, the stabilized antibody firstly entraps the related analyte (antigen), then the entrapped antigen is identified and measured with the help of the second marked antibody. Sandwich method has very high selectivity and sensitivity because it uses two similar antibodies.

At the same time with its simplicity (the lack of the need for complicated synthesis procedures), the nanocomposite synthesized in this research increased the sensitivity in the process in comparison with other methods reported in the references due to its increase in the surface. The other advantage in the designing and production of immunosensors is that it does not need surface blocking materials such as bull albumin serum. The reduction in incubation time between antibody and antigen, and selectivity are among other characteristics of this immunosensor.
