Assistant Professor Dr Ipsita Pradhan, Department of Liberal Arts, has recently published a book review on the renowned LSE Review of Books website. In her recent review, Dr Pradhan offers insightful perspectives on the book Confidence Culture by Shani Orgad and Rosalind Gill. This crucially important book appeals to media studies, American studies, and feminist scholars, as well as a wide public audience.

Dr Ipsita Pradhan elaborates on how the book assures that self-love affirmations in contemporary times are not free from the disciplinarian gaze of the market and its neoliberal capitalist mechanisms, as it is often measured through one’s productivity. She commends the authors’ rigorous research and compelling arguments, stating that the book offers a much-needed critique of the prevailing cultural narrative around confidence.

“In Confidence Culture, Shani Orgad and Rosalind Gill explore the demands that the cultural imperative of confidence particularly places on women. Enriched by abundant examples drawn from across popular culture to show how ‘confidence culture’ puts the onus on individuals to navigate and solve systemic problems, this book is necessary reading for scholars of gender, media studies and sociology”, writes Dr Ipsita Pradhan.

Complex IoT networks comprise multiple devices connected to the gateway. A smoother functioning is ensured through new techniques for device authentication to the gateway. On this note, the research paper titled “A Lightweight Mutual and Transitive Authentication Mechanism for IoT Network” has been published by Dr Amit Kumar Mandal, Assistant Professor, Department of Computer Science and Engineering and his research scholar Mrs Rudra Krishna Srija in the Q1 Journal Ad Hoc Networks, Elsevier having an impact factor of 4.8. The research details the use of the polynomial-based protocol in enhancing device connection for transitive communication.

Abstract of the paper

In large and complex IoT systems like the smart city or smart industry which consist of thousands of connected devices, it may not always be feasible to be directly connected to the gateway but it may be possible to be connected to another device. Therefore, already authenticated devices should facilitate the new device’s authentication by the gateway. To address this issue, the existing protocols use multiple authentication protocols based on different cryptography techniques, which are difficult to implement and manage in resource-constrained IoT devices. In this paper, we propose a Transitive device authentication protocol based on the Chebyshev polynomial.

The work is primarily aimed at improving transitive communication in machine-to-machine communication or device-to-device communication in large-scale heterogeneous IoT network scenarios. The research team targets to investigate the benefits of adopting the designed protocol in particular within low-power and lossy networks in the future.

The Department of Physics is pleased to announce that Professor Ranjit Thapa, Dean-School of Engineering and Sciences (SEAS) and Professor of Physics along with his PhD scholar, Mr E S Erakulan, has published a groundbreaking paper titled “Scrutinizing the Role of Tunable Carbon Vacancies in g-C3N4 Nanosheets for Efficient Sonophotocatalytic Degradation of Tetracycline in Diverse Water Matrices: Experimental study and theoretical calculation” in the prestigious Chemical Engineering Journal with an impact factor of 16.744. The paper offers crucial insights into the role of controllable defects in the sonophotocatalytic degradation of tetracycline (TC) antibiotics from polluted water.

Abstract of the paper

Metal-free polymeric graphitic carbon nitride (CN) materials are robust and stable visible-light-driven photocatalysts that have recently piqued interest in photocatalytic applications. Its photocatalytic performance is restricted remarkably due to moderate oxidation ability and fast charge carrier recombination rate. To address these issues, we engineered carbon-vacant CN (FCN) using a facile formalin-assisted thermal polymerization of molten CN precursor in which the carbon vacancies (C v ) were regulated by altering formalin dosage. Consequently, FCN catalysts revealed C v concentration-dependent sonophotocatalytic degradation of Tetracycline (TC) antibiotics over diverse water matrices. The optimal FCN exhibited complete TC degradation efficiency within 60 min with a synergy index of 1.4, which is approximately 2.6 times higher than that of pristine CN. The enhanced sonophotocatalytic performance was mainly due to the synergistic effect of ultrasound and light irradiation. The C v formation also resulted in enhanced charge carrier transportation and facilitated oxygen adsorption at the C V site of FCN – supported by both experimental study and theoretical calculation. Subsequently, FCN generated abundant reactive active oxygen species including, •O 2 –, as well as indirectly •OH which played a significant role in the degradation pathway and mineralisation of the TC molecules. This study provides insight into understanding the correlation between controllable defects and sonophotocatalytic degradation properties of the self-doped and deficient FCN.

In this research, Prof. Thapa and his team utilised a facile formalin-assisted thermal polymerization technique to fabricate metal-free polymeric graphitic carbon nitride (CN) materials. These materials have been gaining increasing interest as photocatalysts, although their photocatalytic performance has been restricted due to moderate oxidation ability and fast charge carrier recombination rate. To address these issues, the researchers engineered carbon-vacant CN (FCN) by regulating carbon vacancies (Cv) with formalin dosage. The optimal FCN catalyst exhibited complete TC degradation within 60 minutes with a synergy index of 1.4, which is approximately 2.6 times higher than pristine CN.

Emerging pollutants, such as antibiotics discharged from pharmaceutical companies, have detrimental effects on living organisms and can cause drug resistance through gene transmission. The removal of TC from water requires efficient and sustainable strategies. A detailed understanding of the synergistic effects of the defect and self-doped CN in sonophotocatalytic degradation could pave the way for the destruction of various recalcitrant pollutants in an aqueous environment.
