About

Our research is centred around the development of nanomaterials and nanostructured materials for various applications with an emphasis on energy applications, such as photovoltaics and electrochemical energy storage.

Carbon-based nanomaterials and their nanocomposites with polymers are an important focus area. It includes graphene, reduced graphene oxide, graphene quantum dots, carbon quantum dots and their polymer nanocomposites for use in low-cost and high-performance supercapacitors, and counter-electrode of dye-sensitized solar cells.

We also develop various semiconductor materials, including 2D materials like MoS2, for the same applications. Band-gap tuning, doping, and surface chemistry modifications and making nanocomposites are some of the methods we use to improve the performance of these materials in the different applications.

We are interested in developing materials for photo-electrochemical production of fuels including and hydrogen and hydrocarbons, using sunlight and CO2. It involves the understanding of the material’s electronic structure, carrier concentration, mobility, trap density, carrier diffusion length and interaction with the electrolyte.

Another focus area is the development of solution chemistry methods for thin film and third generation solar cell fabrication in order to reduce fabrication cost, while maintaining high performance.

We also collaborate with others laboratories in the centre for other application of the materials in areas such as drug delivery, environmental sensors, biosensors and so on.

Research

Electrodeposition of Metals, Alloys and Compounds :

We use electrodeposition as a synthesis strategy to developed controlled morphologies and compositions of thin films of metals, alloys and compounds.
We have studied electrodeposition of bismuth from acidic baths and deposited different morphologies of bismuth films by choice of bath composition (including additives), pH and deposition conditions. We have electrodeposited SnBi and SnIn alloys from acidic baths for microelectronic packaging and have shown that it is possible to deposit alloys of a wide range of compositions (e.g., 14% to 75% Sn, including eutectic alloys) with smooth morphologies and good surface coverage. We are working on developing the flip-chip technologies for indium, tin-bismuth and tin-indium alloys. We have shown, for the first time, that it is possible to electrodeposit bismuth iodide and oxyiodide thin films of controlled stoichiometries from a single bath.

Ongoing research : 

Presently, we are interested in understanding the synthesis-structure and structure-property relationships in electrodeposition of metals, alloys and compounds. We seek collaborations in modelling and simulation of electrodeposition of bismuth, tin-bismuth alloy and bismuth iodide from different baths, particularly the nucleation and crystal growth phenomena.

Electrochemical Sensors : 

We have developed bismuth-based and graphene-based electrochemical sensors for the detection of various analytes including heavy metals (particularly lead ions) in water, biomolecules in urine and serum matrices (dopamine, uric acid and ascorbic acid, collaboration with Dr. Nikhil Kothurkar – CEMS), antioxidants and nutrients in food matrices (ascorbic acid, folic acid, ferulic acid, vanillin), and macronutrients (NPK) in soils (collaboration with Dr. A. Purushothaman – Electronics and Communication Engineering). Towards understanding and designing graphene-based sensors, we have employed semi-empirical simulations of graphene oxide-analyte interactions.

Ongoing research :

We are interested in developing real-time electrochemical sensors for detection of heavy metal ions and macronutrients (NPK) in water and soil. To this end, the sensor technology is being standardized and collaboratively, we are developing portable potentiostat and the required instrumentation. We have initiated studies of degradation of screen-printed electrode materials in water and soil matrices. We seek collaborations on systems-level simulations of sensor networks employing such devices.

Water Distribution and Quality Management :

We are developing feasible, affordable and versatile technology solutions for real-time management of water distribution and quality. In an ongoing study, we are examining how to minimize the number and optimize the placement of water flow/pressure sensors in large water distribution networks for real-time localization and detection of leaks in the networks. This is a collaboration with Dr. Vidhya Balasubramanian (Computer Science and Engineering). We are developing packed bed electrochemical reactors for removal of heavy metal ions from wastewater. In this system, we are also exploring the simultaneous production of hydrogen by water electrolysis. We are also developing filters for heavy metal ions using cementitious materials (collaboration with Dr. Manu Santhanam and Dr. Mathava Kumar of IIT Madras). We are designing and developing continuous reactors for electrocoagulation- and advanced oxidation-based removal of various pollutants from water including pesticides and dyes.

About the Lab

The research focus of this lab is to functionalize carbon nanomaterials for the sensor and non-linear optical applications. Our research interests also include synthesis of cobaloximes with new or modified equatorial and axial ligands, biologically and medicinally important organic molecules.

Porphyrin-based functional photonic materials have been the cornerstone of research because of their structural rigidity, thermal stability, photochemical, and electrochemical properties. Linking porphyrins to material systems can improve the photochemical and redox properties of the systems. To facilitate the absorptivity of photo absorbers in case of photochemical devices nano materials are functionalized with chromophores such as porphyrin, metalloporphyrin and azo molecules. Our report shows that Porphyrin functionalized carbon nanomaterial shows high third order non-linear optical properties.

Our research interests also include the design and synthesis of cobaloximes with new or modified equatorial and axial ligands. Cobaloxime complexes are among the best synthetic transition metal catalysts known for H2 production. Our interest here to synthesize and characterize new organometallic compounds for H2 production. We reported single crystal X-ray structure of many new cobaloximes. Thermotropic liquid crystalline properties of cobaloxime have been reported for the first time. The crystal structures of various organic compounds with medicinal, biological and pharmaceutical importance have been reported from our lab.
