Application-driven industrial-scale manufacturing of Li/Na-ion battery cathodes
The advent of the industrial revolution increased the dependency of humans on fossil fuels which led to an increase in environmental degradation. While alternative energy sources such as wind, solar and hydro seem to be good options, their uncertainty in delivering the power made Dr Sujith Kalluri, Assistant Professor in the Electronics and Communication Engineering Department and his PhD scholar Chanakya Karra at SRM University-AP prefer batteries as a viable option. “Application-driven Industrial-scale Manufacturing of Li/Na-ion Battery Cathodes” is a paper published by Dr Sujith Kalluri and Mr Chanakya Karra in the Journal of The Electrochemical Society having an Impact Factor of 3.721 as part of their project to develop zero-emission energy methods.
Through this article as a platform, the authors focus on three aspects of energy storage devices that are essential while the world is catapulted to upgrade itself from fossil fuels to electric vehicles. From a battery level perspective, they have discussed the dependence of the battery industry on lithium-ion technology and its repercussions. As a solution, they suggest the distribution of the dependency on sodium-ion technology owing to its adaptability and wide availability. From the cathode level perspective, the paper suggests co-precipitation through the CSTR as a customized solution to address the setbacks in the synthesis process and additive manufacturing as a preferred solution to cater for the desired electrode design specifications that would comply with the needs of future generations and the industry. Till the battery energy storage system paves the way for Na to take over, we can reckon on SC-NCM cathode material to serve the needs.

Dr Nimai Mishra’s research group develops a new synthetic strategy to make ultra-stable CsPbBr3 perovskite nanocrystals for light-emitting application
Dr Nimai Mishra, Assistant Professor in the Department of Chemistry, SRM University-AP, Andhra Pradesh, along with his research group comprising of students pursuing PhD under his supervision, Mr Syed Akhil and Ms V.G.Vasavi Dutt have published a research article titled “Bromopropane as a Novel Bromine Precursor for the Completely Amine Free Colloidal Synthesis of Ultra-Stable and Highly Luminescent Green-Emitting Cesium Lead Bromide (CsPbBr3) Perovskite Nanocrystals” in the Journal “Nanoscale” (The Royal Society of Chemistry, Impact Factor-7.8).
Recently, lead halide perovskite nanocrystals (PNCs) have attracted intense interest as promising active materials for optoelectronic devices. However, their extensive applications are still hampered by poor stability in ambient conditions. In this work, Dr Mishra’s research group report an open-atmospheric, facile, efficient, completely amine-free synthesis of caesium lead bromide perovskite nanocrystals using a novel bromine precursor, bromopropane, which is inexpensive, and available at hand. Their finding concludes that the PLQY can maintain 83% of their initial one even after 120 days. Furthermore, after 96 h of continuous irradiation by UV light with 365 nm (8 W/cm2) in the open ambient condition the photoluminescence (PL) intensity showed retention of 68% of its original value with no significant change in full width at half-maximum, whereas amine-based sample retains only 5% of its original PL intensity. Furthermore, Dr Mishra’s group has fabricated stable down-converted LED devices with these perovskite nanocrystals.
“More importantly, the present work demonstrates the synthesis of ultra-stable CsPbBr3 NCs which can be an ideal candidate for display applications”, says Dr Nimai Mishra.

Dr Sarita Vig on “Wonders of Cosmos”
Electronics and Communication Engineering (ECE) department of SRM University-AP in association with The Institute of Engineers (India), AP State Chapter and the Institution of Electronics and Telecommunication Engineers (IETE) Vijayawada Chapter has conducted a webinar titled “Wonders of Cosmos” on Saturday, April 17, 2021, at 3.00 pm through Zoom. The guest speaker Dr Sarita Vig from the Department of Earth & Space Sciences at IIST, Thiruvananthapuram, Kerala highlighted the basics of astronomy enlightening on the fundamentals and overview of the high-end telescopes found globally.
Addressing the session, Dr CV Sriram, Hon. Secretary of IEI APSC opened the virtual podium to other dignitaries. Dr Geetha Devi from IETE introduced Dr Sarita Vig; Er. Kalee Prasad, Honourable Secretary; and Dr Ramanjaneyulu Fiete, Chairman of IETE. Dr Sujith Kalluri from the ECE department at SRM University-AP was the coordinator and organiser of the event.
Dr Sarita in her presentation elaborated on the different types of telescopes and observatories such as the CGRO, HST, SIRTF, CHANDRA. She discussed the elements responsible for the inception of the universe and the astrophysical processes behind it. Further, she talked about other planets which can be considered as a potential place for habitat like our earth. She also mentioned the supernova remnant crab nebula which was exploded billions of years ago and was even witnessed in the daylight, as per Chinese and Mexican researchers.
Towards the end of the session, Dr Sarita presented the facts about the black hole in the centre of the massive galaxy M87. “In 2019, Event Horizon Telescope helped to get the image of the black hole in radio wavelength. The universe is expanding and it is not in a static form,” she said. The webinar came to an end with an interactive Q&A session between the panellists and participants.
SRM University AP collaborates with Harvard Business School Online
SRM University opens the gates to new opportunities for students, alumni & faculty members as it collaborates with the world-renowned educational institution
SRM University, AP a top-notch and new age university situated in the heart of Andhra Pradesh, collaborates with Harvard Business School Online to offer high-impact online courses to its students. Eliminating the difference between borders and nations, the university is focused on providing global exposure to the students and opportunities to upskill themselves with a gamut of courses to stay relevant in the ever-changing economy. Students already enrolled in flagship programs and courses of SRM University, AP such as School of Entrepreneurship and Management Studies will now have an added advantage to enhance their calibres with the global association.
The collaboration with Harvard Business School Online reflects international unison in these unprecedented times and is further offering different programs such as Business Analytics, Economics for Managers, Financial Accounting, CORe(Credentials of Readiness) and others. These programs are integrated with the regular courses of SRM University, AP such as BBA, MBA (General), MBA (Business Analytics) and MBA (Banking and Financial Services).
Harvard Business School Online offers a unique and highly engaging way to learn vital business concepts. The online certificate and credential programs are offered via HBS On line’s innovative online platform and are designed to bring the Harvard Business School classroom experience to life.
