CSE students complete Semester Abroad Programme at UC Davis

Barukula Snehitha Naga Sai and Kamma Samhitha are two brilliant third-year Computer Science Engineering students selected for the enviable Semester Abroad Programme (SAP) at the University of California, Davis. The students received a partial scholarship from SRM University-AP to complete their final semester abroad with the global study programme at UC Davis. The selection process for the semester abroad programme generally starts at the end of the 3rd and 5th semesters when our university carries out student interviews. A minimum of 8.7 CGPA is required to be eligible for the SAP scholarship and the programme focuses on building engineering design processes along with developing behavioural and communication skills of meritorious students.

The Study Abroad Programme provided Snehitha and Samhitha with the opportunity to cooperate with industrial designers. For practical hands-on experiences, Snehitha worked for the UC Davis school of nursing. Besides that, UC Davis promotes a variety of student clubs and technical programmes that bring students from all over the world together. This opportunity also helped students to live in a new culture and travel through different cities abroad. Prof Ragunathan and Dr Priyanka from the Department of Computer Science and Engineering constantly supported the students throughout their semester abroad journey at UC Davis.

For engineering graduates, technical skills and hands-on experience with industry is inevitable. SRM University-AP ensures that every student grabs opportunities to excel in their respective disciplines.

Snehitha extended her gratitude to all her professors at SRM University-AP who guided her to this achievement. “I really appreciate the curriculum structure at SRM AP that offers us practical knowledge rather than forcing us to memorise theories. The concrete understanding of the subject aided me greatly in learning about real-world problems, and accomplish this dream of studying a semester abroad”, she said.

This programme has taught me how to be adaptable, resilient and above all, how to make the best use of resources available. I have been and am fortunate to study from the best professors, both at SRM AP and UC Davis”, said Samhitha.

Undergraduates bring off one more patent to SRM University-AP

Young researchers from Mechanical Engineering- S.K Hassan, M.Vijaya Bhargava, Jithin Peram, and Meghana Bonthu- have added one more laurel to SRM University-AP by inventing something novel! Under the supervision of faculty from the Department of Mechanical Engineering, the quartet have published a patent A Comprehensive Disinfection System during Pandemic for Personal Items and Protective Equipment(PPE) to Safeguard People.

The current Covid-19 pandemic has led to an enormous demand for gadgets/objects for personal protection. To prevent the spread of the virus which proliferates also through surface transmission, it is important to disinfect objects of common use. One of the ways suggested is to use a UV-C disinfecting box that is efficient and effective in deactivating the COVID-19 virus. The novelty of the product prototype is the use of a UVC transparent material (fused silica quartz glass tubes). This not only physically supports the objects to be disinfected but also improves the effectiveness of disinfection. The aluminium foil which the students have used, a UV reflecting material, was used as the inner lining of the box for effective utilization of the UVC light emitted by the UVC lamps. Care has been taken to prevent leakage of UVC radiation out of the system. COVID-19 virus can be inactivated in 5 minutes by UVC irradiation in this disinfection box.

This novel product can help in efficiently sanitizing normal household items such as mobile phones, keys, purses, grocery and also PPE kits (masks, gloves, visors etc.). This product is not only affordable but also makes disinfection faster. Moreover, the operational process is simple – open the door, place the objects, turn it on and then retrieve them sanitised within minutes.

“We are looking forward to taking up this UV Box to the next stage of implementation with a more compact and more efficient mechanism”, says the proud team behind the invention. “We are ready to undertake new projects and with the help and support from Dr Venkat Nori and other faculty members”, they added.

Dr Nimai Mishra’s research group studies new surface capping ligands

Dr Nimai Mishra, Assistant Professor, Department of Chemistry, SRM University-AP, Andhra Pradesh, along with his research group pursuing PhD under him-Ms V.G.Vasavi Dutt and Mr Syed Akhil- have published a research article titled “Enhancement of Photoluminescence and Stability of CsPbX3 (X= Cl, Br, and I) Perovskite Nanocrystals with Phthalimide Passivation” in the Journal “Nanoscale” (The Royal Society of Chemistry, Impact Factor-7.8).

Caesium lead halide perovskite nanocrystals (CsPbX3 NCs) have been the flourishing area of research in the field of photovoltaic and optoelectronic applications because of their excellent optical and electronic properties. However, they suffer from low stability and deterioration of photoluminescence (PL) properties post-synthesis. One of the ways to minimize the surface defects in the surface treatment with suitable ligands is to achieve the NCs with superior PL properties for light-emitting applications.

In this article, Dr Mishra’s research group demonstrates that incorporating an additional ligand can further enhance the optical properties and stability of NCs. Here, we introduced phthalimide as a new surface passivation ligand into the oleic acid/oleylamine system in situ to get near-unity photoluminescence quantum yield (PLQY) of CsPbBr3 and CsPbI3 perovskite NCs. We observed, phthalimide passivation dramatically improves the stability of CsPbCl3, CsPbBr3, and CsPbI3 NCs under ambient light and UV light. The PL intensity is recorded for one year which showed a dramatic improvement for CsPbBr3 NCs. Nearly 11% of PL can be retained even after one year for phthalimide passivated samples, on the other hand, the PL of as-synthesized NCs completely diminishes in four months. CsPbCl3 NCs exhibit 3 times higher PL with phthalimide and retain 12% PL intensity even after two months while PL of as-synthesized NCs completely diminishes by then. Under continuous UV light illumination, the PL intensity of phthalimide passivated NCs is well preserved while the as-synthesized NCs exhibit negligible PL emission in 2 days. About 40% and 25% of initial PL is preserved for CsPbBr3 and CsPbCl3 NCs in the presence of phthalimide. CsPbI3 NCs with phthalimide exhibit PL even after 2 days while the PL is rapidly declined for as-synthesized NCs in the first 10 hours. The presence of phthalimide in CsPbI3 NCs could maintain stability even after a week while the as-synthesized NCs under transition to non-luminescent phase within 4 days.

Furthermore, blue, green, yellow, and red-emitting diodes by using CsPbCl1.5Br1.5, CsPbBr3, CsPbBr1.5I1.5, CsPbI3 NCs respectively are fabricated by drop-casting NCs onto blue LED lights which show the great potential of the use of these phthalimide passivated NCs in the field of display and light technologies.

Vivek Vardhan from ECE files design copyright

Bitragunta Vivek Vardhan, a final year student from the Department of Electronics and Communication Engineering, has filed a design copyright for developing a “UV Ray Wooden Sanitizer Disinfection Box”. This is a safe chemical-free product designed to disinfect the surfaces of items. In this period of the Covid-19 pandemic, it has been difficult to sanitize mobile phones, tabs, laptops, car/bike keys, wallets, currency/coins, credit/debit cards, newspapers, pens, goggles, spectacles, accessories, milk packets, bakery items, water-absorbing products, delivery packages, toys, clothes etc with liquid sanitisers or else with water.

Researchers say that the coronavirus stays on surfaces of plastic (3-7 days), stainless steel (3-7 days), copper (up to 4 hours), paper (up to 4 days), glass (4 days), cardboard (24 hours), and wood (up to 2 days). UVC has a wavelength of 10 nm to 400 nm and is used for the disinfection method that has short-wavelength light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions. The UVC light used in the product will not penetrate into solid surfaces and it is safe to use on touchscreen mobiles, laptops, tabs, etc. It is also proven that the disinfection box can destroy the bacteria and viruses on the surface of food items without causing any harm to the edibility.

“In future, I have plans to take this project to the next level by designing large dimensions of the box and making it work automatically with remote control through our mobile phone. I am extremely happy about filing the copyright and I express my heartfelt gratitude to Prof Siva Sankar Sir and Pro VC Prof D Narayana Rao Sir for giving me the opportunity and supporting me to expand my idea up to the level of implementation. And I thank Prof Vinod Kumar Sir for taking care of the filing process. Finally, I thank SRM University-AP for encouraging and nurturing young talents in all ways possible, “ Vivek stated.
