The Department of chemistry has always been a dynamic space for innovative and inspiring research. Recently, Assistant Professor Dr Nimai Mishra published his fifteenth research paper from SRM university-AP as a corresponding author. The paper is titled Post-synthesis Treatment with Lead Bromide for Obtaining Near Unity Photoluminescence Quantum Yield and Ultra-Stable Amine Free CsPbBr 3 Perovskite Nanocrystal and is published in the Q1 journal, The Journal of Physical Chemistry C with an impact factor of 4.2. The research group is comprised of Dr Mishra’s PhD students Mr Syed Akhil, Dr V G Vasavi Dutt, and Mr Rahul Singh. This is the group’s fifth consecutive article published in the American Chemical Society.

About the article

The article reports Ultra-Stable and Near Unity Photoluminescence Quantum Yield Amine Free CsPbBr 3 Perovskite Nanocrystal Post-synthesis Treatment with Lead Bromide. Herein, the researchers have introduced a simple lead bromide (PbBr 2 ) post-treatment process to achieve the near-unity PLQY (>95 %) in amine-free CsPbBr 3 PNCs. Furthermore, PbBr 2 treatment enables these materials to drastically improve stability in different environmental conditions (polar solvents, light, and heat). In addition, a green-emitting down- converted light-emitting diode was fabricated using PbBr 2 treated amine-free CsPbBr 3 PNCs, which shows its considerable prospects for display applications. Thus, the results of the research will promote these PbBr 2 treated amine-free inorganic perovskite nanocrystals for commercial development in optoelectronic applications.

Explanation of the research

Cesium lead halide perovskite nanocrystals (PNCs) have been the flourishing area of research in the field of photovoltaic and optoelectronic applications because of their excellent optical and electronic properties. Mainly, cesium lead bromide (CsPbBr 3 ) NCs with bright green photoluminescence (PL) and narrow full-width at half-maximum (FWHM) of < 25 nm is the most desirable for television displays and green-emitting LEDs. Improving the photoluminescence quantum yields (PLQYs) and optimizing the stability have been challenging tasks to promote cesium lead halide (CsPbX3; X=Cl, Br and I) perovskite nanocrystals (PNCs) for real optoelectronic applications. In recent years, the amine- free synthesis route has become an option for making stable CsPbX 3 PNCs.

No form of art goes beyond ordinary consciousness as film does, straight to our emotions, deep into the twilight room of the soul

– Ingmar Bergman

Inside the dark space of a movie theatre, it’s just us, the screen, and the projecting light against the world. We join the revolt of the artist against the real. The very idea of perceiving the comfort and discomfort of a cinema while sitting with a bunch of unfamiliar faces is enough to make you fall into the rabbit hole of filmmaking.

Ever wondered how people connect with people through mere moving images? Ever think of the stories you want to tell but cannot fix frames and pour life into them? It is the filmmaking enthusiast in you who makes you think of what is in a frame and what is out.

The fascinating thing about cinema is that it is an endless tool made up of pretty much the same elements. Cinema uses the language of dreams and each of them is entirely different from the other. The Movie Club is ready with a filmmaking workshop to awaken the storyteller in you. The workshop offers an intensive and instructional five-day programme focusing on the five main agents of cinema, including Scriptwriting, Direction, Photography, Editing, and Acting.

Date: From July 7 to July 11, 2022

Time: 6 PM

With every good film you see, you feel reborn

The higher education regulatory body, University Grants Commission (UGC) is organising a three-day education summit, Akhil Bharatiya Shiksha Samagam , at Varanasi, Uttar Pradesh, from July 7 to July 9, 2022. The Hon’ble Prime Minister of India, Shri Narendra Modi will grace the occasion by delivering the inaugural address. SRM university-AP is being part of the summit by live-streaming the inaugural event on campus.

Academicians, researchers, policymakers, professional and educational experts, and industry experts from all over the country will gather at the summit to discuss the diverse perspectives of the National Education Policy 2020 and its role in transforming higher education. The workshop intends to analyse the impact of the education policy after the successful implementation of several initiatives in the past two years. The summit will involve thought-provoking conversations on articulating action plans, implementation strategies, multidisciplinary and holistic education, skill development and employability, Indian knowledge systems, etc. It will also consider the challenges being faced by educational institutes and articulate solutions.

Date: July 07, 2022

Time: 2.30 pm

Venue: Tiered classroom Level- V, Admin Block

Procrastination is irrational and existential at its core. The ambiguous nature of self-awareness makes us feel rotten and glad at the same time while putting things off for a moment. It is a coping mechanism to resist the challenging emotions caused by the sight of certain tasks. That’s why procrastination is never an issue of time management but emotion regulation. It becomes a habit and not a once-in-a-blue-moon phenomenon.

The Department of Student Affairs is coming up with a talk on Today is the new Tomorrow – Beat procrastination, which will be handled by Student Counsellor Ms Sridevi Srinath.  It’s time to break the ties between procrastination and productivity. It has nothing to do with the effectiveness of productive effort but with managing emotions. This session will help you break the procrastination cycle and develop an action plan that works for you.

Date: July 07, 2022

Time: 4 pm to 5 pm

About the speaker

Ms Sridevi Srinath has been in the field of counselling for over eight years. She holds an MSc in Counselling Psychology from Madras School of Social Work and an MPhil in Psychology from the University of Madras. Working in a school previously, she has over five years of experience in impacting the lives of children and adults across issues such as anxiety, stress, behavioural changes, soft and life skills, and career guidance, to name a few. She also has certification from UCLA Extension in Career Guidance and Counselling.

He secured admission to MS in Computer Science at Purdue University, Fort Wayne; Texas A&M University, College Station (Distance); Arizona State University, Tempe; Illinois Institute of Technology, Chicago; University of South Florida, Tampa; and the University of Houston. Along with this, he received an offer from the University of Maryland, College Park for the Master of Professional Studies in Machine Learning programme. Admission offers came with a scholarship of $10,000 from ASU and $16,500 from IIT Chicago.

The suitable choice

Rohan has decided to join the MS in Computer Science programme at Arizona State University. He plans to prepare a thesis and focus his research on the field of machine learning. He wants to explore and address the challenges of designing efficient deep learning algorithms for space exploration through telescopic imagery. He is also interested in doing a few courses on theoretical computer science.

Finding the best

For selecting universities, Rohan started by acquiring a list of reputed universities from the QS Rankings website. Then he shortlisted universities by focusing on the course curriculum, faculty, and resources for student research. He has completed his bachelor’s degree at SRM university-AP with a major in Computer Science and Engineering and a minor in Physics.

Support from SRM AP

The mentorship of accomplished faculty has helped Rohan build strong foundational knowledge in his discipline. Through the course projects, UROP, and the Capstone Project, he has developed research skills and built a compelling profile essential for admission to leading universities in the USA. He expressed his gratitude to his professors and mentors, Prof Dr Ragunathan T, Dr Jatindra Kumar Dash, and Dr Murali Krishna Enduri, for their relentless guidance. He is immensely grateful for the opportunities that he received from SRM university-AP.
