PhD Student Ritika Chaterjee has been awarded the Prestigious Prof. Saroj Chandrasekhar Memorial Award, 2022. This award is instituted by the Chandrasekhar Foundation in memory of Prof. Saroj Chandrasekhar, who has made a significant contribution to tuberculosis research. This is an annual award presented to three women Ph.D. candidates for their doctoral thesis work.
PhD Student Pustam Raut from the Aerospace Engineering department, has been awarded the Hall of Fame & US$5,000 (₹3.75 lakh) by Google for his contributions to the safety and security of its Android ecosystem. He has discovered a High Severity bug/vulnerability and reported it to Google’s Android Security Team in 2021. Google’s Android Security Rewards (ASR) program has acknowledged his contributions on their Hall of Fame page. (Link: https://source.android.com/security/overview/acknowledgements?authuser=1#february-2022 and googlehof). They have also awarded me $5,000 USD for this work. The vulnerability, rated as High (S2), could lead to information disclosure with no additional execution privileges and no user interactions needed for exploitation. The vulnerability has been fixed and the AOSP versions 10, 11 & 12 have been updated with the 2022-02-05 security patch level.
Ms. Shruti Soni, from Dr. Bhushan Toley’s group, has been awarded the DST-AWSAR award (third prize) in the Ph.D. category for writing a popular science story on her Ph.D. research work (Non-invasive, low-cost paper-based glucose detection using saliva as the sample). DST organizes AWSAR (Augmenting Writing Skills for Articulating Research) program to popularize and unleash the spirit of science communication among young scientists. Her popular science story titled “Pain-free way to manage your sugar rush” addresses an essential aspect of diabetes management that presently includes invasive and painful methods of monitoring blood sugar levels. The story suggests a more user-friendly diagnostic bodily fluid that can be collected in a non-invasive and pain-free manner and can be used to monitor glucose levels.
Mr. Rajesh Srinivasan, PhD student in the Department of Instrumentation and Applied Physics, has been selected for the prestigious Gandhian Young Technological Innovation Award (GYTI), 2020. The accolade is for the project to develop a cost-effective method to count CD4 cells and to tackle the HIV condition in rural parts of India.
CD4 (T-cell) count is important to determine HIV infection condition in an individual. Conventional techniques are expensive and could not be accessed in resource-limited regions. This project has been designed with a motive to develop a cost-effective method to count CD4 cells and to tackle the HIV condition in rural parts of India. Basic automated Haematology analyzers are commonly available in rural diagnostics labs. By utilizing the analyzer’s capability to count cells and combining our technology of target cell separation, it is possible to count CD4 cell levels with minimal handling procedure. The highlight of this work is the 3-step process diluting whole blood, incubating it with antibody conjugated SPIONs (superparamagnetic iron oxide nanoparticles) and analysis using the hematology analyzer. With these three simple steps, it is possible to determine the CD4 cells count to monitor HIV condition. This technique will create a significant impact in the society by reducing the deaths due to HIV and decrease the rate of new infections. The motivation for this project is to develop a low cost CD4 counting method for HIV infected patients in resource-limited settings like rural parts of India. The major element to reduce the cost of the test is eliminating the need for flow-cytometer. The next important part that is actually a frugal innovation is using the automated hematology analyzer (replacing the flow-cytometer with hematology analyzer). These hematology analyzers are a common clinical laboratory instrument, hence the total cost of the test reduces to less than 150 (INR) from the current testing cost of 2000(INR).
Mr. Sukanta Nandi, , Ph.D. student, Department: Instrumentation and Applied Physics, receives Dr. K. V. Rao Scientific Society Research Award in Physics. The 20th KVRSS Science Award event was held online on 16th September where Mr. Nandi was awarded the first prize in the Physics category. The award is presented by Dr. K.V. Rao Scientific Society, a non-profit organization with the head office stationed at Hyderabad, Telangana, India. The research awards are presented to young scientists (Research Scholars and Doctorates), below 30 years of age, from various branches of basic sciences every year. The award carries a cash award of Rs. 20,000/- only and a trophy for the winner and a cash award of Rs.10,000/- only and a trophy to the runners-up in each category- Chemistry, Physics, Biology, and Mathematics.
Title of presentation : Spray Coating of Two−Dimensional Suspended Film of Vanadium Oxide−Coated Carbon Nanotubes for Fabrication of a Large Volume Infrared Bolometer. A vanadium oxide−coated multiwall carbon nanotubes (MWCNT) based suspended bolometer was fabricated by novel spray coating and transfer method. The obtained temperature coefficient of resistance of suspended bolometer was ~486% higher than that reported in the literature for WCNT bolometer. Suspension of the CNT film reduces thermal link with the environment and thus effectively improves the bolometric performance. The developed fabrication technique also allows to attain a thin continuous transparent film of CNT with more than 95% transparency in a wide optical spectrum at room temperature. Spray coating of nanometre scale thick film thus provides a versatile platform to bring highly tuneable device performance on any kind of transparent and flexible substrates.
This work thus provides further insights into bolometric performance of MWCNT−based sprayed suspended bolometer. Further, the spray coating of such films together with the transfer technique opens avenues for developing high performing, large scale flexible devices. Reference: Nandi, S. and Misra, A., 2019.
