INUP-i2i Familiarisation Workshop The Ministry of Electronics and Information Technology (MeitY) established the Indian Nanoelectronics User’s Programme (INUP) about a decade ago with the intention of improving skilled manpower in the areas of micro and nanoelectronics. This has laid the necessary foundation for the next step of the programme, INUP-i2i. It is a matter of pride that four PhD students from the Department of Chemistry attended the INUP-i2i Familiarisation Workshop on Nanofabrication and characterisations held from August 10 to 12, 2022, at IIT Kharagpur. Mr Syed Akhil, Mr Rahul SIngh, Mr Manoj Palabathuni, and Mr Subarna Biswas are the scholars who have grabbed this incredible opportunity.

Indian Nanoelectronics User’s Programme- Idea to Innovation (INUP-i2i) is developed to facilitate and support the generation of expertise in Nanoelectronics through participation and utilisation of the facilities at Nano-centres at IISc Bangalore, IIT Bombay, IIT Delhi, IIT Kharagpur, IIT Madras, and IIT Guwahati.

INUP will provide easy access to state-of-the-art nanofabrication and characterisation facilities to researchers, thereby creating a critical mass of hands-on experimental researchers across the country. This workshop is being organised both for familiarisation and interaction of the participants with faculty members of IITKGP. INUP has provided the accommodation and food for these shortlisted students. At the end of the workshop, they presented a poster as well.

The prospects and challenges in India-ASEAN relationsThe upcoming international conference, India & Southeast Asia in a Changing World: Convergences and Divergences, will examine India’s Act East policy, investigating its prospects and challenges in the Southeast Asian region. Assistant Professor Dr Vineeth Thomas from the Department of Liberal Arts has been selected for presenting a paper at this Conference organised by Christ University, Delhi NCR. He will present the paper titled The centrality of ASEAN in India’s Act East policy at the conference.

The international conference will be held In-Person from 14 to 15 October 2022 at the CHRIST (Deemed to be University) Delhi-NCR campus. The Hanns Seidel Foundation funds this conference. The major focus area of the conference is India’s foreign policy towards ASEAN countries like Myanmar, Thailand, Malaysia, Vietnam, Indonesia, and Singapore

Abstract

Against the backdrop of multi-dimensional developments and interventions in the Indo-Pacific region, India’s overseas policy and national security apprehensions have undergone substantial changes in the past few decades. Starting with the Look East Policy in the 1990s, India advanced its policy in 2014 as Act East Policy. The potential benefits of bilateral and multilateral relations in the Indo-pacific region made India take up its partnership with the Association of Southeast Asian Nations (ASEAN) seriously, which provided an opening and strip for India to explore Southeast Asia. This paper evaluates the significance of keeping ASEAN at the heart of India’s Act East Policy by illustrating the prospects and challenges in India-ASEAN relations.

Effect of grass clippings on anaerobic co-digestion of food waste The different dimensions of sustainable waste management have always been explored by researchers all over the world. Assistant Professor Dr Pankaj Pathak, Department of Environmental Science, has been actively involved in this research area for a while. Her paper titled Dual role of grass clippings as buffering agent and biomass during anaerobic co digestion with food waste is published in the journal Clean Technologies and Environmental Policy with an impact factor 4.7. Dr Pankaj Pathak co-authored the paper with Debkumar Chakraborty, Sankar Ganesh Palani, M M Ghangrekar, and N Anand.

Abstract

There is a dire need to replace the chemical buffers that regulate the redox environment in single-stage anaerobic digestion of food waste. Hence, the applicability of grass clippings as an eco-friendly buffering agent and biomass during the anaerobic co-digestion of food waste was explored. A focus was primarily given on the effects of grass clippings on the redox environment and acidogenesis. Concomitantly the production of volatile fatty acids, hydrogen, and methane in mesophilic conditions was monitored. Organic load and substrate-to-inoculum ratio were kept constant in all the experiments, and no chemical buffer was used. The results revealed that the redox environment was regulated with 10% grass clippings by inhibiting rapid pH drop in the digester. The addition of 2, 4, and 6% grass clippings promoted acidogenesis with increased production of acetic and butyric acids, whereas 8 and 10% grass clippings promoted solventogenesis with ethyl alcohol production. Hydrogen generation from the experiments with grass clippings was in the range of 27–30% of the total biogas, which was marginally higher than the control (25%). Methane concentration was negligible in the biogas generated from all experiments. The acidification rate, VFA production/consumption rate, specific hydrogen yield, hydrogen conversion efficiency, and volatile solids removal were maximum and minimum in the reactors with 6 and 10% grass clippings, respectively. From the above results, it can be concluded that adding grass clippings to food waste would regulate the sudden pH changes and enhance the production of value-added biochemicals, making the process cost-effective.

The Department of Civil Engineering is delighted to announce that Dr Siddhant Dash has published a paper titled “Systematic bibliographic research on eutrophication-based ecological modelling of aquatic ecosystems through the lens of science mapping” in the journal “Ecological Modelling” having an Impact Factor of 3.512. This research was conducted in collaboration with Prof Ajay S Kalamdhad from IIT Guwahati.

Research SRMAP

This research is a systematic approach on reviewing the published literature on eutrophic-ecological models developed worldwide and the methods associated with them. This provides critical insights into the status of the research domain, thereby providing a direction for the practising and future researchers to undertake a research career in this domain. It offers a more comprehensive and holistic approach to the critical review of the published literature, providing a deeper understanding to the researchers regarding the existing practices of developing eutrophication-based ecological models and the prospects lying ahead. His future research plans include understanding carbon and nutrient dynamics within an aquatic ecosystem.

Abstract of the Research

When water bodies receive surplus nutrients, especially nitrates and phosphates, these nutrients stimulate excessive plant growth (eutrophication), including harmful algal blooms, leading to oxygen depletion, decreased biodiversity, changes in species composition and dominance, and degradation of water quality. Although there are natural causes, much of the eutrophication today results from inadequately treated wastewater and agricultural runoffs. Population pressure, urbanization and industrialization contribute a considerable amount of waste, which alters the physio-chemical quality of water that eventually upsets the biotic components of the aquatic system. It is important to note that though pollution has been a significant factor in degrading the quality of aquatic ecosystems, the lack of management and global awareness regarding the protection and conservation of water bodies worldwide cannot be neglected. Hence, there lies an inherent sense of responsibility to restore the aquatic ecosystems to their natural state. Numerous techniques/treatment options are available for varying conditions, such as climatic factors, socio-economic factors, and so on. However, before ascertaining a treatment alternative to curb eutrophication levels, understanding the dynamics of any independent aquatic ecosystem is of prime importance. This necessitates a reliable model, which can provide information regarding the physical processes and dynamic occurrences in the eutrophic water bodies. Ecological modelling refers to the formation of dynamic and complex relationships between the organisms found in the ecosystem and the surrounding. It attempts to unravel the effects of certain relationships in the ecosystem that are not so apparent at first glance. The present study provides a scientific investigation of a detailed review of the published works in the domain of eutrophication-based ecological modelling till the year 2020. The first step was the scientometric studies, which were followed by a qualitative assessment wherein the current trends in research were discussed. This was followed by identifying the critical gaps in research to provide future direction.
