Soha Muskaan Sayyad, Samah Maaheen Sayyad, Juhita Naga Priya Velagapudi, and Trisha Chilukuri from 2nd-year Computer Science Engineering have achieved 2nd place in the I-Wallet Design Techfest, organised by IIT Bombay. Dr Sonam Maurya, Assistant Professor, Department of Computer Science and Engineering, guided the students to achieve this incredible feat.

The students started their work in December and explored a lot about IoT while working on it. More than 100 teams participated in this competition. In January, ten teams got selected for the second round, i.e., Report Submission, and our students were one of them. In February, based on the reports submitted, six teams, including our students, were selected for the final round, i.e., to present the proposed idea to the judges’ panel. Finally, the students bagged second place in the competition with cumulative prize money of INR 90,000.

Regarding the I-Wallet, students say that “Smart Wallet is an easy-to-use wallet that is designed for providing secured transactions”. It has minimal energy consumption, more security, and a few advanced features, some of which are not included in the regularly used wallets. The advanced IoT features enable it to be kept in our pockets with smartphones and smartwatches. The design received recognition from the expert panel members based on these features.

The team has also initiated the process to file a patent on the design of wallet. Students expressed their gratitude to Dr Sonam Maurya, Assistant Professor, Computer Science and Engineering, for her relentless guidance and continuous support towards the project. They also thanked SRM University-AP for providing the opportunity to participate in this national level competition organised by IIT Bombay.

Prof B V Babu, Dean, School of Engineering and Sciences, appreciated the students and their faculty mentors. “Keep up the good work, continue to excel in all your future endeavours at professional and personal levels and bring laurels to your alma mater”, he said in the congratulatory message.

Mr Mudigonda Himansh, a 3rd-year BTech-CSE student, has presented a research paper in the IEEE International Conference on Innovations in Information Technology-2022 organised by IIIT Kottayam, Kerala India, in Feb-2022. The paper will be published in IEEE Xplore (Scopus indexed). Dr V M Manikandan, Assistant Professor in Computer Science and Engineering at SRM University-AP, is the co-author of the presented paper titled “A Statistical Study and Analysis to Identify the Importance of Open-source Software”.

Open-source software has picked up pace in the past decade with support from multinational conglomerates and huge open-source communities. We hear a lot about the success of many open-source projects, but we fail to understand how many do not make it. In this paper, Mr Himansh and Dr Manikandan understand the dynamics behind open-source software. They start with the need for open-source alternatives. Then look at a few concerns open-source software developers and maintainers face. Next, we would understand the various requirements of open-source software. Later, we would touch upon the different attributes that affect the selection of open-source software and the decisions to make while building general-purpose, open-source software. Then we would analyse the 5-determinants of open-source software success. Finally, we would look at the data collected from 482 data points from 24 countries and then analyse the data by forming graphs and charts.

This research provides the required knowledge to the open-source and non-open source software developers before-during-after development and production of the software or project. “Our future work is focused on the applications and predicting the scalability of large-scale OSS with machine learning,” says Dr Manikandan.

SRM University-AP is indeed proud of its young and intelligent minds who continue to bring honour and glory to the institution from across the globe. Pulkit Jasti and Tankala Yuvaraj, two of our students from the Department of Computer Science Engineering currently pursuing Semester Abroad Programme at the University of California, Berkeley have won first prize in the prestigious SF Hacks conducted by San Francisco State University, USA, and bagged a total of $950 ($600 for 1st Prize, $250 for Best UI/UX Design, and $100 for Best AIML Hack).

The world has always been ruled and sustained by ideas. Innovating and executing the unthinkable are what helped us tide over the unprecedented hardships the pandemic entailed. SF Hacks 2022, San Francisco’s largest collegiate hackathon was conceived to hatch some striking ideas under the tracks: inclusivity, mental health, sustainability, and machine learning to put the latest technologies to use in the fittest way possible to render solutions to the unending maladies of corona and climate change.

Pulkit Jasti and Tankala Yuvaraj have tread out of the way to introduce an AI-based classroom system that monitors the mental-well being of the students. It is an unfortunate fact that our classrooms have often overlooked the emotional and mental well-being of the students. The transition to virtual mode has made the scenario even worse. Researches state that the depression rates in students between ages 10-18 have increased by 72% since the pandemic.

According to Pulkit and Yuvaraj, this incredible innovation monitors various parameters like facial expressions, voice, attentiveness of a student during the class and generates a meta score that gives an overall idea about the mental well-being of the student. Based on this score, the school counsellors will be notified and then the student can have a one on one therapy session with the counsellor. This system can help identify signs of depression at early stages which makes classroom a safe learning environment for students.

They were determined to come up with an effective solution to redefine the conventional classroom setup and make learning a wholesome experience. “After selecting a problem and drafting the base of the project, we were assured that it could create a positive impact for students during these unprecedented times of the Covid-19 outbreak”, they said.

“During the hackathon, we ran into a lot of technical issues and roadblocks but were able to overcome them and submit our final prototype. To be a part of such a huge event where there were around 1000+ participants from over 26 countries was indeed a remarkable learning experience”, they expressed their feeling of contentment. “We can never thank enough our faculty at SRM for their enormous support throughout our journey at the University of California Berkeley” they added.

“Highly Efficient Catalysts of Ruthenium Clusters on Fe3O4/MWCNTs for Hydrogen Evolution Reaction” is the latest paper published by Prof Ranjit Thapa, Professor of Physics at SRM university-AP and his PhD scholar, Mr Samadhan Kapse, in ‘New Journal of Chemistry’ having an Impact Factor of 3.591.

In this work, the chemical co-precipitation technique is adopted to produce Fe3O4 nanoparticles under an inert atmosphere and was utilized for HER studies. The Ru nanoparticles were profitably deposited over Fe3O4/MWCNTs GC electrode using electrochemical deposition technique. The superior HER activity was achieved on Ru/Fe3O4/MWCNTs in 0.1 M H2SO4 aqueous media. We have demonstrated that the synthesized electrocatalyst offers a low overpotential of 101 mV to achieve a current density of 10 mA cm-2 towards the hydrogen evolution reaction. It displays long-term durability, exceptional cyclic stability even after 1000 cycles. DFT calculations imply that the availability of both octahedral and tetrahedral sites in Ru/Fe3O4/MWCNTs with low overpotential is more efficient towards HER. It is emphasized that a low percentage of ruthenium in the prepared catalyst can be substituted as a promising HER catalyst for sustainable energy technologies.

Abstract of the paper

Producing molecular hydrogen (H2) using water provides a sustainable approach for developing clean energy technologies. Herein, we report highly active ruthenium clusters (Ru) supported on iron oxide (Ru/Fe3O4) and Fe3O4/multi-walled carbon nanotubes (Ru/Fe3O4/MWCNTs) by simple electrochemical deposition in a neutral aqueous medium. The supported catalyst exhibits good hydrogen evolution reaction activity (HER) in an acidic environment. Cyclic voltammograms (CV) in potassium ferrocyanide (K4[Fe(CN)6]) confirm MWCNTs enhance the electron transfer process by decreasing the redox formal potential. The overpotential of Ru/Fe3O4/MWCNTs and Ru/Fe3O4 electrocatalysts versus reversible hydrogen electrode (RHE) was found to be 101 mV and 306 mV to reach a current density of 10 mA cm-2 . As prepared, the catalyst displays good stability and retain its HER activity even after 1000 cycles. Further, the stability of Ru/Fe3O4/MWCNTs was studied using chronopotentiometric (CP) technique for 12 hrs and found negligible loss in the catalytic activity towards HER. To explore the role of Ru and underneath MWCNTs to improve the catalytic performance of Fe3O4, density functional theory (DFT) calculations were carried out. DFT calculations indicate the octahedral site of Ru/Fe3O4 favours HER with low overpotential. However, Ru/Fe3O4/MWCNTs is more efficient towards HER could be due to the availability of both octahedral and tetrahedral catalytic sites.

Social implications of the research

Renewable energy generation is of greater importance in the present circumstances. This is caused by the depletion of non-renewable energy sources like fossil fuels and other hydrocarbon deposits and the release of greenhouse gases into the atmosphere. Hydrogen has gained considerable interest as an energy storage and energy carrier because of its high energy density (146kJ/g). Furthermore, its lightweight, profusion nature and the release of water during its combustion eliminate environmental pollution and thus contribute to defeating the global energy crisis. Also, hydrogen is an important and ideal energy source to develop fuel cells. A number of methods have been explored to generate molecular hydrogen. Among them, water electrolysis is a promising technology for generating high-purity hydrogen from water. An excellent electrocatalyst is obligatory to liberate hydrogen gas effectively from water. A higher HER activity is known to be obtained from platinum (Pt) and Pt-based catalysts. Given its high cost and low surplus, it limits expansion to the industrial scale. Over the few past decades, lots of efforts have been made by many research teams to find out alternative catalysts to substitute Pt electrodes.

The paper is published in collaboration with Shwetha Kolathur Ramachandra, Doddahalli Hanumantharayudu Nagaraju, and Shivanna Marappa; School of Applied Sciences, REVA University, Bangalore-560064, Karnataka, India. According to the research group, the density functional theory can boost the searching process of highly promising electrocatalysts for hydrogen evolution reactions in renewable energy generation.

The Department of Chemistry is glad to announce that Dr J P Raja Pandiyan has published a paper titled ” Microfluidics and surface-enhanced Raman spectroscopy, a win-win combination?” in the journal ‘Lab on a Chip’ having an impact factor of 6.79 in collaboration with researchers from different universities across India, Germany, and Japan.

Abstract of the Research

With the continuous development in nanoscience and nanotechnology, analytical techniques like surface-enhanced Raman spectroscopy (SERS) render structural and chemical information of a variety of analyte molecules in ultra-low concentration. Although this technique is making significant progress in various fields, the reproducibility of SERS measurements and sensitivity towards small molecules are still daunting challenges. In this regard, microfluidic surface-enhanced Raman spectroscopy (MF-SERS) is well on its way to join the toolbox of analytical chemists. This review article explains how MF-SERS is becoming a powerful tool in analytical chemistry. We critically present the developments in SERS substrates for microfluidic devices and how these substrates in microfluidic channels can improve the SERS sensitivity, reproducibility, and detection limit. We then introduce the building materials for microfluidic platforms and their types such as droplet, centrifugal, and digital microfluidics. Finally, we enumerate some challenges and future directions in microfluidic SERS. Overall, this article showcases the potential and versatility of microfluidic SERS in overcoming the inherent issues in the SERS technique and also discusses the advantage of adding SERS to the arsenal of microfluidics.
