Yet another groundbreaking achievement for the researchers at SRM University-AP! Prof. Ranjit Thapa, Dean-Research and Professor, Department of Physics, Prof. G S Vinod Kumar, Professor and Head, Department of Mechanical Engineering and Ms Harsha K, PhD scholar, continue to make their mark in the university’s excellent research legacy by having their patent “Tarnish Resistant Silver Composition and a Process for its Preparation” being granted by the Indian Patent Office. This innovative research team has used density functional theory to explain the tarnishing of silver. Their work also focuses on finding alloying elements that protect silver.

Abstract

The research is on the development of tarnish-resistant silver alloys from an experimental and computational perspective. With time, silver atoms on the surface of the metal undergo sulphidation and form Ag2S molecules. These particles will accumulate to form a layer whose thickness goes beyond 10nm, and then the human eye will start to find a discolouration on the surface of silver, which is tarnish. The stain colour changes from light yellow to dark brown. This reduces the lustre of silver and makes them aesthetically non-pleasing. The silver jewellery and articles manufacturing industry suffers from this tarnishing as it leads to the loss of material and money and ruins intricate designs made of silver. The research study attempts the problem by alloying silver with appropriate elements, which are computationally checked and verified. The team works with alloying elements such as Cu, Zn, Ge, Ti, Zr, Mg, Al, and Be. Along with tarnish resistance, the proposed alloys maintain high reflectance, good hardness, and excellent workability when spinning.

Practical implementation/social implications of the research

• Stainless silver is in demand as customers want their precious metal articles to be kept for a longer time as heirlooms. So, the product that we could develop out of our composition will be making more demand for silver.
• It can increase the market potential of silver.
• It can lead to more innovations in the jewellery industry.

Collaborations

• Waman Hari Pethe
• Ashlyn Chemmannur
• TITAN

The team would continue to work on the scope of research to develop more tarnish-resistant compositions, improve the tensile strength, scratch resistance, surface hardness, and workability of silver alloys and find novel elements which can add to desirable properties of silver.

The Department of Electrical and Electronics Engineering is glad to announce that the paper titled “A Comparative Analysis of Non-Isolated Bi-directional Converters for Energy Storage Applications”, authored by Dr Tarkeshwar Mahto, Dr Somesh Vinayak Tewari, Dr Ramanjaneya Reddy, Assistant Professors and Ms K Mounika Nagabushanam, PhD Scholar has been published in the IOPs Engineering Research Express having an impact factor of 1.7. The paper explores various non-isolated bi-directional DC-DC converter topologies for renewable energy systems, providing insights into their performance and suitability for different applications.

Abstract

Bi-directional DC-DC converters (BDC) are required for power flow regulation between storage devices and DC buses in renewable energy-based distributed generation systems. The fundamental requirements of the BDC are simple structure, reduced switching components, a wide range of voltage gain, low voltage stress, high efficiency, and reduced size. There are different BDC topologies for various applications based on the requirements in the literature. Various BDCs are categorised according to their impedance networks. Isolated BDC converters are large due to high-frequency transformers and hence used for static energy storage applications whereas non-isolated BDC is lightweight and suitable for dynamic applications like electric vehicles. This paper reviews types of non-isolated BDC topologies. The performance of five non-isolated BDC converters under steady-state conditions is evaluated using theoretical analysis. On this basis, the suitability of BDC for different applications is discussed. Further advantages and limitations of converters are discussed by using comparative analysis. The optimisation of BDC for distributed generation systems from the perspectives of wide voltage gain, low electromagnetic interference, and low cost with higher efficiency is identified. Theoretical analysis of the converters is validated by simulating 200W converters in MATLAB Simulink.

The main challenges with energy storage systems are frequent failures due to frequent charging and discharging and the volume of the power converter. The team plans to:

• To design a converter with fewer components, low switching stresses, high power transfer capability, and higher efficiency to deliver continuous current to the energy storage system.
• To work on various control techniques to keep the DC link voltage of the propulsion system constant.

Dr M Durga Prakash, Assistant Professor in the Department of Electronics and Communication Engineering, and his PhD scholar, Ms U Gowthami, have published a research paper titled “Performance Improvement of Spacer-engineered N-type Tree Shaped NSFET towards Advanced Technology nodes” in the Q1 journal, IEEE Access. The paper has an impact factor of 3.9 and will pave the way for significant advancements in the field.

Here’s an abstract of their research paper

Abstract:

Scaling gate lengths deep is most reliable with tree-shaped Nanosheet FETS (NSFET). This paper uses TCAD simulations to study the 12nm gate length (LG) n-type Tree-shaped NSFET with a stack of high-k dielectric (HfO2) and (SiO2) spacers. The Tree-shaped NFET device features high on-current (ION) and low off-current (IOFF) with T(NS) = 5 nm, W(NS) = 25 nm, WIB=5nm, and HIB = 25 nm. Comparison of single- and dual-k spacer 3D devices and DC properties are shown. Because fringing fields with spacer dielectric prolong the effective gate length, the dual-k device has the highest ION / IOFF ratio, 109, compared to 107. This research also examines where work function, inter bridge height, breadth, gate lengths, temperature, and analog/RF and DC metrics affect the device. The suggested device has good electrical properties at 12 nm LG, with DIBL = 23 mV/V, SS = 62 mV/dec, and switching ratio (ION / IOFF) = 109. The device’s performance proves Moore’s law applies to lower technological nodes, enabling scalability.

The water crisis in India, especially in the coastal regions, has worsened alarmingly, coercing environmentalists and researchers to critically study the reason behind this phenomenon. The Sundarbans region faces a scarcity of drinking water in terms of quality and quantity due to various reasons. Dr Kousik Das, Asst. Professor, Department of Environmental Science and Engineering, Dr Harish Puppala, Asst Professor, Department of Civil Engineering and Mr Mijanur Mondal, Research Scholar from the Department of Environmental Science and Engineering has conducted a groundbreaking study on the increased salinization of water due to human activities. The research trio has published a paper titled “Understanding the susceptibility of groundwater of Sundarbans with hydroclimatic variability and anthropogenic influences” in the prestigious Q1 journal Groundwater for Sustainable Development, which has an impact factor of 5.9, critically analysing the numerous factors that affect the quality of drinking water in the Sundarbans region.

Abstract

Coastal aquifers worldwide are experiencing increased salinisation due to climate change and human activities. Sundarbans, in India, is one such area where this phenomenon is noticed at an unprecedented rate, making drinking water unpotable for consumption. Existing studies lack a comprehensive analysis of the underlying causes. This study conducts a systematic literature review to identify drivers of groundwater salinisation, examining climate change parameters such as rainfall patterns, sea level rise, El Niño-Southern Oscillation, and tropical cyclones. Significant groundwater level declines from 1996 to 2017 are primarily attributed to variations in the Indian Ocean Dipole and El Niño Southern Oscillation, affecting rainfall and recharge rates. During tropical cyclones, groundwater levels rise rapidly, and quality is sensitive to El Niño Southern Oscillation. Rising sea levels, changing rainfall, and increasing population density worsen salinisation. Shallow aquifers have high salinity, whereas deep aquifers exceed permissible limits. This underscores the urgent need to address drinking water scarcity and potential migration resulting from complex interactions between climate, population, and groundwater management.

Social Implications of the Research

• Water Quality Monitoring: Implementing regular monitoring of salinity levels in groundwater to ensure compliance with safety standards.
• Community Awareness Programmes: Conducting educational campaigns to inform local communities about the risks of high salinity levels in drinking water and promoting the judicious use of water sources so that unscientific abstraction can be reduced.
• Policy Development: Formulating policies at the local and national levels to regulate salinity levels in drinking water and ensure public health protection.
• Infrastructure Improvement: Investing in water treatment facilities or technologies to remove high salt levels from groundwater sources. Alternative sources and rainwater harvesting can be taken into consideration.

Collaborations – IIT Kharagpur, India

The research team plans to work on Groundwater vulnerability modelling using AI/ML in Sundarbans, India next. The team has begun collecting primary data using questionnaire surveys and interviews to throw light on socio-economic conditions and to understand the core reasons for the water crisis and health and psychological issues due to water unavailability, especially during extreme events like cyclones.
