Breakthrough in Mathematical Research: Dr Subha Sandeep Repaka’s Innovative Study on Unitary Groups
The Department of Mathematics, SRM University-AP, is pleased to announce that Assistant Professor Dr Subha Sandeep Repaka has published a significant research paper titled “On Reducibility of Induced Representations of Odd Unitary Groups: The Depth Zero Case.” This accomplishment reflects Dr Repaka’s expertise and dedication to advancing mathematical research, further enriching the academic contributions of the department and the university.
Abstract:
We study a problem concerning parabolic induction in certain $p$-adic unitary groups. More precisely, for $E/F$ a quadratic extension of $p$-adic fields the associated unitary group $G=\mathrm{U}(n,n+1)$ contains a parabolic subgroup $P$ with Levi component $L$ isomorphic to $\mathrm{GL}_n(E) \times \mathrm{U}_1(E)$. Let $\pi$ be an irreducible supercuspidal representation of $L$ of depth zero. We use Hecke algebra methods to determine when the parabolically induced representation $\iota_P^G \pi$ is reducible.
Future Research Plans:
We would like to solve the same problem which I had solved in this paper for the groups U(n,n) and U(n,n+1) over p-adic fields using L-Functions which is a very novel approach.

Dr Narayanamoorthy’s Review on Pt-based Electrocatalysts Features in Elsevier Journal of IF 20.8
With the rising frequency of climate crises and to address growing energy demands and environmental concerns, a shift from conventional fossil fuels to sustainable alternatives is essential. As Hydrogen fuel cells are a viable and sustainable alternative to conventional fossil fuels, various research is being conducted in maximising the efficiency of fuel cells.
Dr Narayanamoorthy Bhuvanendran, Assistant Professor from the Department of Environmental Science and Engineering, works extensively in this field and has recently reviewed the advancements in Pt-based electrocatalysts that can reduce the Oxygen reduction rate (ORR) in Hydrogen fuel cells in his research paper. The paper titled “Recent progress in Pt-based electrocatalysts: A comprehensive review of supported and support-free systems for oxygen reduction” was published in the Q1 journal Coordination Chemistry Reviews with an impact factor of 20.8.
Abstract
Recent advancements in Pt-based catalysts for the oxygen reduction reaction (ORR) have improved energy conversion efficiency in fuel cells and metal-air batteries. However, balancing electrocatalyst activity and stability remains challenging. Due to Pt’s high cost and limited availability, research focuses on Pt alloys, hybrid catalysts, and nanostructured materials to enhance catalytic performance using cost-effective methods. Hybridising Pt with other active components offers synergistic effects and aligns with the U.S. Department of Energy’s 2025 targets. This review examines recent developments in supported and support-free Pt-based electrocatalysts, highlighting carbon, inorganic, and hybrid support materials, as well as support-free metal nanostructures, for superior ORR performance in energy applications.
Explanation of the Research in Layperson’s Terms
Hydrogen, with its abundance and eco-friendly properties, is a promising fuel for sustainable energy systems, powering vehicles like electric cars and buses through efficient energy conversion devices such as fuel cells. While fuel cells effectively convert hydrogen into electricity, further advancements in electrocatalysts and cost-efficiency are needed to make this technology commercially viable. The oxygen reduction reaction (ORR) in fuel cell cathodes requires efficient catalysts for better performance. Pt is the top ORR catalyst for low-temperature fuel cells due to its ability to break O-O bonds efficiently. However, issues like Pt nanoparticle dissolution, surface impurities, and structural changes during reactions limit its effectiveness. This review explores improving electrocatalysts by increasing active sites, boosting metal-support interaction, and enhancing stability for better performance.
Practical Implementation/ Social Implications of the Research
Several challenges remain in scaling Pt-based electrocatalysts for oxygen reduction reaction (ORR), particularly around cost, performance, and environmental impact. Platinum’s high cost and scarcity drive up production costs, and synthesis methods are complex and hard to scale. Catalyst durability also degrades over time in industrial conditions. Efforts are focused on developing green synthesis methods, recovering platinum from used catalysts, and exploring alternatives like atomic layer deposition to reduce Pt usage while enhancing efficiency. New nanostructures, such as 2D layers and hybrid materials, could balance performance and cost. Future research aims to meet the U.S. Department of Energy’s 2025 targets for improved performance and durability, essential for advancing Pt-based electrocatalysts and enabling widespread fuel cell adoption.
