Research Statement

Current research is focused mainly on chemical processing and characterization of nanostructured materials and coatings for energy related applications as well as biosensors and biomedical applications. Emphasis of our research is on the control and tailoring the crystallinity, surface chemistry, bulk and surface defects and morphology to attain desired electrochemical or optoelectrochemical properties of the active materials for energy conversion and storage applications. Our recent research can be grouped into following directions:

• Nanostructured electrodes for alkaline-ion batteries and pseudocapacitors
• Perovskite, dye- or quantum dot-sensitized and inverted polymer solar cells
• Nanostructured catalytic membranes and solid electrolytes for efficient ion transport
• Nanostructured materials for chemical and bio-sensors
• Nanostructured materials for catalysis applications
• Dielectrics, ferroelectrics, and piezoelectric films and devices

Past research experiences:

• Coherent porous carbon – hydride nanocomposites for hydrogen storage
• Oxide scintillation films for neutron, ɤ-ray and X-ray detection
• Growth of homoepitaxial and textured diamond films by chemical vapor deposition (CVD)
• Electrochemical vapor deposition (EVD) of complex oxide films on porous substrates as electrolyte and electrode for solid oxide fuel cells (SOFCs)
• Porous and dense organic-inorganic hybrid xerogels, aerogels, and films by sol-gel processing
• Mixed ionic-electronic oxide conductors and oxygen permeable ceramic membranes
• Silicon oxynitride structural ceramics
