Our research, encompassing theory and experiments, earlier at the Indian Institute of Technology, Kanpur, and now at the Indian Institute of Science, Bangalore, has the following key objectives:-
to significantly improve understanding of in vitro cell functionality modulation on engineered implantable biomaterials using an electric field stimulation approach;
to investigate the synergistic role of substrate properties (conductivity, stiffness, wettability, surface patterning) and the intermittent delivery of pulse electric/magnetic stimulation to modulate neurogenic/osteogenic/myogenic differentiation of human mesenchymal stem cells, in vitro (without differentiation inducers)
to understand the bactericidal effect in pathogenic bacterial strains using magnetic field stimulation;
to synthesize novel polymeric scaffolds with tunable physical and biocompatibility properties;
to fabricate complex three-dimensional scaffolds with a controlled porosity gradient using an additive manufacturing technique (3D printing);
- To advance concepts of a superfast densification-based processing approach to controlling the microstructure of toughened structural ceramics over multiple-length scales for hypersonic cruise vehicles and tribological applications.
- Development of ZrB2-SiC based composites with excellent aero-thermo-structural stability and designed thermal protection system for long endurance hypersonic flights
Solar energy materials
Over the last few decades, Concentrating Solar Power (CSP) technology have been perceived as one of the most promising and economical solar technologies wherein, solar radiation is converted into higher or lower grade thermal energy. The construction of CSP plants is expected to fulfill our growing energy demand and a further growth for this renewable technology demands the development of advanced solar reflector and absorber materials with excellent optical properties and long-term stability.
Our research group is currently part of a larger consortium of Indo-US Solar Energy Research Institute (SERIIUS). In line with the broader objectives of this unique multi-institutional research program, the researchers in our group are also developing solar-selective novel bulk/coating materials for Concentrated Solar Power (CSP) systems, which have been envisaged as a potential environmental friendly technology to produce electricity from abundant solar energy. Apart from the above-mentioned solar reflector materials, a key component of an efficient photo-thermal conversion system is the solar selective absorber coating that absorbs concentrated photons. The essential requirements for such solar selective absorber coatings are high absorptance (ð¼ â¥ 0.95) in the solar spectral range (0.3â2.5 ðm) and low thermal emittance (ð â¤ 0.05) in the infrared region (2.5â25 ðm).
In the above broad perspective, a major emphasis has therefore been placed on identifying the optimal mirror material composition having the best combination of specular reflectance property, hardness and self-cleaning capability.
We actively collaborate with the research group of Dr. Harish C Barshilia, Chief Scientist & Head of Surface Engineering Division, CSIR-National Aerospace Laboratory, Bangalore.
