Redefining information-centric IoT networks in the internet architecture

Dr Satish Anamalamudi, Assistant Professor, in the Department of Computer Science and Engineering has published a research paper titled “Cooperative Caching Scheme for Machine-to-Machine Information-Centric IoT Networks” in the IEEE Canadian Journal of Electrical and Computer Engineering. The research paper is co-authored by Dr Mohammed Saeed Alkatheiri and Dr Eesa Al Solami of University of Jeddah, Saudi Arabia and Dr Abdur Rashid Sangi of Yibin University, China.

According to the authors, Information-centric networks (ICNs), a foreseen future Internet architecture, focuses on the application content rather than its hosting location. With this, the existing Internet protocol (IP)-based host-centric communication model can be transformed into a content-centric communication model with the support of in-network caching, name-based routing, and location-independent content domain names. Recently, ICN is proposed to be a potential Internet architecture for Internet-of-Things (IoT) networks due to minimal retrieval delays and reduced load on the data producer. Content retrieval from IoT nodes plays a prominent role in enhancing the performance of the ICN-IoT networks. The in-network caching of ICN enhances the data availability in the network, overcome the issue of single-point failure, and improve IoT devices power efficiency. In this work, the authors explore a cooperative caching scheme for information-centric-IoT networks to optimize the cache hit with the support of a caching network topology model, a content popularity model, and an exogenous request access model.

Dr Satish says that ICN proposes to shift the existing complex Internet model to a simple and generic one. This approach considers the content as the first-class network citizen. In ICN, contents are addressed and routed by their unique names and are decoupled from the address of the node storing it. In this way, consumers ask for information by its name rather than its locality address. In ICN, every content is identified by using a unique, persistent and location-independent name. A wide set of IoT applications is inherently information-centric. In fact, the majority of IoT applications target data regardless of its source. For instance, environmental monitoring applications are oblivious to the information origin. ICN is a promising candidate for IoT environments. It can natively support IoT scenarios while improving data dissemination and reducing network complexity.

Dr Satish Anamalamudi had been a Research Engineer with Huawei Technologies, Beijing, China. He also worked with the Huaiyin Institute of Technology (HYIT), Huai’an, China, until February 2018. He is currently an Assistant Professor with the Department of Computer Science and Engineering, SRM University-AP, Andhra Pradesh. His research interests include the common-control-channel design for MAC and routing protocols in cognitive radio ad hoc networks, MAC, and routing protocol design of Internet of Things (IoT) and 5G networks.

Application-driven industrial-scale manufacturing of Li/Na-ion battery cathodes

The advent of the industrial revolution increased the dependency of humans on fossil fuels which led to an increase in environmental degradation. While alternative energy sources such as wind, solar and hydro seem to be good options, their uncertainty in delivering the power made Dr Sujith Kalluri, Assistant Professor in the Electronics and Communication Engineering Department and his PhD scholar Chanakya Karra at SRM University-AP prefer batteries as a viable option. “Application-driven Industrial-scale Manufacturing of Li/Na-ion Battery Cathodes” is a paper published by Dr Sujith Kalluri and Mr Chanakya Karra in the Journal of The Electrochemical Society having an Impact Factor of 3.721 as part of their project to develop zero-emission energy methods.

Through this article as a platform, the authors focus on three aspects of energy storage devices that are essential while the world is catapulted to upgrade itself from fossil fuels to electric vehicles. From a battery level perspective, they have discussed the dependence of the battery industry on lithium-ion technology and its repercussions. As a solution, they suggest the distribution of the dependency on sodium-ion technology owing to its adaptability and wide availability. From the cathode level perspective, the paper suggests co-precipitation through the CSTR as a customized solution to address the setbacks in the synthesis process and additive manufacturing as a preferred solution to cater for the desired electrode design specifications that would comply with the needs of future generations and the industry. Till the battery energy storage system paves the way for Na to take over, we can reckon on SC-NCM cathode material to serve the needs.

Dr Nimai Mishra’s research group develops a new synthetic strategy to make ultra-stable CsPbBr3 perovskite nanocrystals for light-emitting application

Dr Nimai Mishra, Assistant Professor in the Department of Chemistry, SRM University-AP, Andhra Pradesh, along with his research group comprising of students pursuing PhD under his supervision, Mr Syed Akhil and Ms V.G.Vasavi Dutt have published a research article titled “Bromopropane as a Novel Bromine Precursor for the Completely Amine Free Colloidal Synthesis of Ultra-Stable and Highly Luminescent Green-Emitting Cesium Lead Bromide (CsPbBr3) Perovskite Nanocrystals” in the Journal “Nanoscale” (The Royal Society of Chemistry, Impact Factor-7.8).

Recently, lead halide perovskite nanocrystals (PNCs) have attracted intense interest as promising active materials for optoelectronic devices. However, their extensive applications are still hampered by poor stability in ambient conditions. In this work, Dr Mishra’s research group report an open-atmospheric, facile, efficient, completely amine-free synthesis of caesium lead bromide perovskite nanocrystals using a novel bromine precursor, bromopropane, which is inexpensive, and available at hand. Their finding concludes that the PLQY can maintain 83% of their initial one even after 120 days. Furthermore, after 96 h of continuous irradiation by UV light with 365 nm (8 W/cm2) in the open ambient condition the photoluminescence (PL) intensity showed retention of 68% of its original value with no significant change in full width at half-maximum, whereas amine-based sample retains only 5% of its original PL intensity. Furthermore, Dr Mishra’s group has fabricated stable down-converted LED devices with these perovskite nanocrystals.

“More importantly, the present work demonstrates the synthesis of ultra-stable CsPbBr3 NCs which can be an ideal candidate for display applications”, says Dr Nimai Mishra.

Controlled loading of MoS2 on hierarchical porous TiO2 for enhanced photocatalytic hydrogen evolution

Ever since the breakthrough research on H2 photogeneration from water using TiO2 under UV-light irradiation, an enormous amount of research has been conducted on photochemical H2 evolution using different semiconductor-based photocatalysts. Consequently, a research paper titled “Controlled Loading of MoS2 on Hierarchical Porous TiO2 for Enhanced Photocatalytic Hydrogen Evolution” has been published by Prof Ranjit Thapa, Professor of Physics, SRM University – AP, as a co-author, in The Journal of Physical Chemistry C, having an Impact Factor of 4.189.

In this work, Prof Thapa describes three important factors for helping in the generation of hydrogen using proposed MoS2/TiO2 catalyst, (i) TiO2 for effective charge transfer, (ii) MoS2 for plasmon induction (iii) large surface area and active sites. It was shown that hierarchical porous TiO2 can be interfaced successfully with marigold-flower-like MoS2 flakes with intriguing photophysical properties, viz., visible-light response, controlled electron−hole recombination, and sustainable H2 production over prolonged light irradiation due to the synergic effect of flowerlike MoS2 and the fibrous wormhole mesoporous channel of TiO2. Further, the researchers have used density functional theory (DFT) to identify the active sites and calculated the change in Gibbs free energy (ΔGH). “We have also studied the charge density difference to understand about electron transfer pathway. The change free energy of hydrogen adsorption (ΔGH*) is a good indicator to estimate the hydrogen evolution activity in the acidic medium. From the DFT study, it is clear that O sites of MPT heterostructure are more favourable for HER reactivity”, said Prof Ranjit Thappa.

Social implications of the research:
In the last few decades, with the decline in non-renewable resources and increasing environmental pollution, significant attention has been given to renewable and clean energy domains. Hydrogen is considered one of the most suitable energy carriers due to its higher energy density per unit mass in comparison to other chemical fuels. In recent times, photocatalytic fission (Photocatalysis is a process in which light energy is used to drive pairs of chemical reactions. Through the absorption of light, an excited electron/hole pair is produced) of water has been considered an attractive solution for solar to chemical H2 energy conversion. Also, the process of water splitting is highly endothermic. Therefore, the development of an excellent, stable, efficient, and economical photocatalyst for ultrahigh H2 production efficiency is paramount to researchers.

This work is done in collaboration with the Department of Energy and Environmental Engineering, CSIR-Indian Institute of Chemical Technology, Hyderabad 500007, India.

Prof Ranjit Thapa is doing an investigation to find the possibility of hydrogen evolution reaction (HER) on multiple borophene analogues (α, β12, χ3) on all unique sites. Understanding the role of the coordination number of the boron atoms in the borophene analogues with the HER efficiency, and studying the pathways Volmer-Tafel (V-T) on each site to understand the completed HER process on borophene analogues are his future research projects. His research group is also interested to identify the role of sigma and pi-electron occupancy on the V-T pathway.
