Research

Dr. Guduru is currently conducting research in the following areas

  • Corrosion of Metals, Preventative Coatings and Solutions (e.g. Hydrophobic Materials and Thermal Spray Coatings Coatings etc.)
  • Failure analysis of materials (e.g. weld joints, fatigue and fracture, corroded components, pressure vessels, valves, pipes and tubing, and structural components) 
  • Carbon Dioxide (CO2) capture
  • Processing of Nanomaterials and Nanocrystalline Materials
  • Energy Storage (Batteries, Supercapacitors, and Microbial Fuel Cells) and Solar Energy 
  • Waste material recycling for energy applications

Energy Storage 

Although there has been a tremendous improvement in the energy densities of Li-ion batteries, their power densities are still very limited. Our current research focus is on understanding and developing of multivalent ion based supercapacitors and batteries with a particular focus on Magnesium, Beryllium and Aluminum-ion technologies to enhance the energy and power densities of energy storage devices. Initial studies on multivalent-ion supercapacitors have demonstrated high power densities with excellent stability and longer life cycles. Advances in this research could potentially bridge the gap between the batteries and supercapacitors in terms of energy and power densities as well as help reduce the use of fossil fuels for automotive applications.

Energy Harvesting using Marshland Grass

Today's world needs more renewable sources of energy such that the wheel of industrial development keeps running without hampering the environment. Plant-microbial fuel cells (PMFC) provide a 100% eco-friendly source of energy with almost zero carbon footprint. In this project, we are using marshland grass along with metal electrodes to generate electricity.

CO2 Capture Technologies

The key driving force behind this project is to find cost-effective solutions for decreasing the greenhouse gasses by absorbing CO2 from the low concentration sources, such as the atmosphere. We are currently in the process of understanding the kinetics and reaction mechanisms of an electrochemical process to capture CO2 in order to develop a quasi-self-sustainable reactor. This reactor will capture the CO2 and simultaneously generate the electricity to run the reactor in a quasi-self-sustainable mode.

Industrial Research

    • Mechanical Testing of Materials: Evaluation of mechanical properties and correlating them with microstructural parameters is very vital to assess as well as tailor the materials for different applications. This project deals with miniaturized and cost-effective mechanical testing methods to determine the properties of structural materials. Currently, a small-scale specimen testing technique -"shear punch test" is being utilized to understand the effect of residual elements on the mechanical properties of steels.

    • Failure Analysis of Materials: The focus of this project is to evaluate the effect of environment, working conditions, structural parameters on the mechanical properties of steels and weld joints used in oil and chemical industries.
