Nikhila Korivi offers revolutionary approach to ensure Data Security

Nikhila Korivi, third year, Department of Computer Science and Engineering, SRM University- AP, Andhra Pradesh was steered by Dr Manikandan V M, Assistant Professor, Department of CSE, to present the pioneering research paper “Reversible Data hiding in encrypted images using checkerboard based pixel inversion” in the IEEE International Conference on Computing, Communication and Security (ICCCS-2020), IIT Patna, held on October 14-16, 2020.

Nikhila and her mentor, Dr Manikandan V M, worked on the paper conjointly for which, she is profoundly grateful to the professor. She says, “I thank Dr Manikandan and my other professors at SRM University-AP for their continuedguidance that inspired me to do research. Their encouragement propelled me to successfully present the research paper at ICCCS-2020, a conference revered by the entire scientific community.”

Nikhila has been keen on exploring and broadening her horizon of knowledge. Right from her early undergraduate days, Nikhila was intrigued by Information Security, an emerging discipline in the modern era. Soon she recognized that Reversible Data Hiding is an active research area in the realm of Information Security, which has extensive application in Medical Image Transmission, and Cloud Computing.

On approaching her professor, Dr Manikandan enthused Nikhila to embark on the research work and propose a new Reversible Data Hiding scheme in encrypted images by using a checkerboard pattern-based pixel inversion technique. Nikhila informs, “The proposed scheme ensures a better bit error rate without compromising on the embedding rate. The algorithms were implemented using Matlab-2019 and the experimental studies of the proposed scheme have been carried out using a standard image dataset (USC-SIPI) managed by the University of Southern California.”

This revolutionary approach is immensely beneficial when it comes to Data Security, and it is widely implemented in medical image transmission along with many other sectors. Fostering her interest in pursuing research and advanced studies, Nikhila plans to enhance her research work by focusing on designing and developing new Reversible Data Hiding schemes with better embedding rates without compromising other efficiency parameters such as computational complexity, robustness, and bit error rate.

Converting waste to fuel: way forward to a resilient planet

Dr Lakhveer Singh, Assistant Professor, Department of Environmental Science published a book titled “Waste to Sustainable Energy: MFCs – Prospects through Prognosis”. This book has been featured in the list of Best Waste Management books of all time by CNN, Forbes, and Inc-Book Authority. The book has been awarded this stature by venerated reviewers of the International Expert Committee, as well as global leaders of the discipline.

A Microbial Fuel Cells (MFC) bio-refinery treat water using microorganisms and converts waste products and byproducts into fuel. This entails efficient waste management along with contributing to the generation of renewable fuel, and products that foster sustainable development. Addressing the present challenges in waste management, bioenergy, bioproduct recovery, and commercial sustainability, this book on MFCs emphasize on an array of mechanisms, routes, and reaction engineering approaches for extensive transformation of waste to wealth.

Extensive use of fossil fuels for energy emits carbon dioxide and other harmful gases adversely affecting the environment and leading to soaring global warming. Subsequently, domestic, agricultural waste products from animal facilities, refineries, and industries cause a tremendous environmental burden. Energy systems from MFCs enable the treatment and recycling of wastes, preventing environmental problems, and offsetting the pollution loads. Dr Lakhveer informs, “We are aiming at ensuring a sustainable and resilient environment that eliminates any potential odds of future climate change. Though globalization has preceded the escalation in production processes, a significant quantum of the waste materials generated through these practices can be transformed into fuels with the help of MFCs. Efficacies of this mechanism would ensure a paradigm shift built on the principles of sustainability.”

This book focuses on the MFCs with various combinations of substrates generating bioelectricity with valued co-products. Essentially, the book provides fundamental ideas on MFC technologies, entailing various design and modeling aspects with examples. Further, the book illustrates distinctive aspects of basic sciences, reactor configuration, application, and market feasibility of MFCs. Critically assessing the feasibility of waste-powered MFCs for sustainable bioenergy production, the book highlights the tradeoff between resource needs and energy production. The extensive research and details in the book will help academicians, entrepreneurs, and industrialists to understand the scope and challenges empowering them to select unique, and specific integrated approaches in unit processes.

Advancing his research to mitigate environmental issues, Dr Lakhveer will continue to explore bioenergy, water treatment, bioelectrochemical systems, and nanomaterial synthesis for energy and water applications, and bioreactors development. Also, he is presently editing two books that address several environmental challenges.

Dr Anil K Suresh is a renowned scientist in the area of Bio-Nanotechnology . The prestigious Ramalingaswami Fellow is now an Associate Professor at the Department of Biology, SRM University-AP. He recently developed an innovative catalyst that he named “Jumbo Catalyst” to address the demanding challenges in heterogeneous catalysis. This 3D-megacatalyst generated using “intact eggshell” food-waste is hand-removable with an overall surface area of ~ 78 cm2, featuring wide catalytic support and is highly stable in polar and non-polar solvents for ultra-efficient heterogeneous catalysis. This megacatalyst can overcome the existing limitations such as cost, time, labour, sustainability, mechanical stability, diverse-reactions, large-volumes, aggregation, recyclability and precursor recovery. Dr Anil K Suresh owns the copyrights for this pathbreaking invention through a published patent.

Catalysis is widely used in various industrial processes to produce desired end products. Research in this area substantially evolved from using organic reagents and metals to the adaptation of metal-based nanoparticles. Supported catalysis is a fast-emerging class of catalysis using inert and supportive frameworks with a potential for efficient reuse and recovery of the catalyst. Synthesis of metal-organic frameworks, fibres, polymers and hydrogel-based catalytic nanoparticle loadings are being reported. However, these are associated with intrinsic complexities and are produced using toxic ingredients, ecologically unbenign and are expensive.

The megacatalyst, generated by Dr Anil and his team using eggshell food-waste in the process, is autogenic, facile, cost-efficient and entirely biodegradable. Dr Anil strongly believes that theirs is the biggest catalyst developed so far. The intact eggshell provides an extensive support area for ultra-efficient catalysis. Applicability of this megacatalyst is so simple that even a layman can use it with ease. Moreover, this supported megacatalyst can be effortlessly removed from the reaction mixture post application as it can be recovered by hand. Catalytic reactions using the megacatalyst can be controlled as the tuff, and uniform coating protects the shedding of nanoparticles. Dr Anil Says, “We presume that the mega-size of the catalyst could be instrumental in several challenging applications. As a proof of concept, we selected three eclectic applications including- 1. Large volume sewage dye degradations, 2. Gram-scale hydrogenation of nitroarenes and 3. Transesterification of used oil to biodiesel- which are all difficult to achieve, highly challenging but are now practically feasible using our megacatalyst.”

“Keeping in mind the ultra-catalytic proficiency of our catalyst that can be simply resourced from continuously available eggshell waste, with minimal maintenance for the large scale practical implementation, we welcome interested beneficiaries from diverse heterogeneous catalysis sectors for bringing this innovation to execution,” Dr Anil asserted.

The team is currently investigating to design and fabricate other species of megacatalyst using other significant metal precursors and earth-abundant metals to expand the applicability in allowance of diverse reactions such as oxidation of CO, Methane, Mono/Polyhydric alcohols, hydrogenation of alkynes, Nitroaromatics and CO2.
Dr Anil K. Suresh concluded that this breakthrough conception would not have been possible without the rigorous efforts of his team and the continuous support from the university management. Dr Anil Suresh thanked his PhD students Chandra Bhatt, Divya Parimi, Tharun Bollu and Madhura. Dr Anil especially thanked Professor D Narayana Rao, Pro-Vice-Chancellor, SRM University-AP for his extensive support in all his scientific endeavours since his association with the university.
