Industrie 4.0 has become increasingly global and cross-industry, driving digital transformation across industries, businesses, and governments. SRM University-AP observes National Engineers’ day with an inspiring talk by Mr Dasari Ramakrishna, Managing Director, Efftronics Systems Pvt. Ltd., on September 15, 2021, at 06.45 pm.

The heartbeat of the Fourth Industrial Revolution is algorithms. While algorithms are not new, the transition of businesses to be algorithmic is game-changing. Mathematicians describe an algorithm as an encapsulated set of rules that act on data to determine an outcome. In today’s digitalized world, companies use algorithms on a daily basis to influence and support decisions (fact-based decision making). In system development, algorithms building is the most challenging and major activity. Often engineers are expected to build completely new algorithms which are not available in the market (internet). One should adopt commonly available algorithms when required. But what is more important is to use various algorithmic concepts/principles together in combination to build a new algorithm. Like any development, algorithms building also follows the cycle of defining, analysing, designing, implementing, and testing iteratively in a systematic way. If one had to build algorithmic thinking, they need to practice with different scenarios, reflect upon the results and experiment continuously.

Every year on September 15, India commemorates Mokshagundam Visvesvaraya’s accomplishments by observing National Engineers Day. Visvesvaraya, the Bharat Ratna awardee, was born in the Karnataka village of Muddenahalli on September 15, 1861. As a pioneer in engineering, he made numerous contributions to the infrastructural backbone of the country.

The third session of the distinguished lecture series organised by the Department of Civil Engineering is scheduled to be held on September 18, 2021, Saturday, from 9:30 to 10:30 am. Dr Ganesh Kumar S, Scientist, Geotechnical Eng. Division, CSIR-CBRI, Roorkee will deliver a talk on the topic “Liquefaction and reliquefaction studies and their mitigation techniques”.

During an earthquake, liquefaction is one of the processes that occur in the saturated loose sand layer. It occurs when the pore water pressure reaches a certain level, which is near to the soil’s total stress. Structures built on top of or within the liquefied ground may fail to owe to ground settlement, which is one of the possible effects. The lecture aims to elaborate on the experimental studies on the liquefaction and reliquefaction potential of saturated ground and the use of ground improvement techniques for its improvement.

Dr Nimai Mishra, Assistant Professor, Department of Chemistry, SRM University-AP, Andhra Pradesh, along with his research group comprising of students pursuing PhD under him, Ms V.G.Vasavi Dutt and Mr Syed Akhil has published a research article titled Cesium Lead Bromide Perovskite Nanocrystals as a Simple and Portable Spectrochemical Probe for Rapid Detection of Chlorides in the Journal ChemistrySelect (Publisher: Wiley-VCH on behalf of Chemistry Europe, Impact Factor-2.2).

Chloride anions are widely abundant in water and when they combine with calcium, potassium, and magnesium, they form chloride salts. However, the higher concentrations badly affect the environment by causing severe dehydration and even plant death. High concentrations of sodium chloride exhibit the potential of corrosive damage thereby releasing toxic metals from plumbing fixtures. Hence, there is a need to monitor the concentration levels of chloride salts in water. Several techniques like titration, spectrophotometry, ion chromatography, electrochemistry, etc have been reported to date. Despite the high accuracy and precision of these techniques, they involve expensive instrumentation and is out of reach from on-site detection. Hence, it is necessary to look for simple, portable, and cost-effective strategies for the detection of chlorides in the water.

In this article, Dr Mishra’s research group demonstrated that the wide spectral tunability of CsPbBr3 perovskite nanocrystals (NCs) via instantaneous and facile anion exchange, make them a suitable candidate for chloride detection. Rapid anion-exchange processes between CsPbBr3 perovskite NCs and different chloride solutions were carried out in ambient conditions. The resultant anion-exchanged CsPbCl3-xBrx NCs preserved the structural properties and exhibited a remarkable blue shift in photoluminescence spectra. This forms a basis for the detection of chloride ions in water. This has been applied with the limit of detection up to 100 µM. The detection strategies were not only limited to the direct addition of chloride solutions to NCs, but they also showed a visual colour change under UV light when the chloride solution is drop-casted on CsPbBr3 films that are deposited on glass substrates. Furthermore, the detection strategy is established by drop-casting CsPbBr3 NCs onto paper strips that are pre-soaked in chloride solutions. A considerable blue shift in fluorimetry proves them to be an excellent sensing medium as practical spectrochemical probes for on-site detection of chlorides. Based on this, a colour chart and selectivity chart to access the presence of chlorides and their concentration is also demonstrated.

A research paper titled “Nitrogen doping derived bridging of Graphene and Carbon Nanotube composite for oxygen electroreduction” has been published by Prof Ranjit Thapa, Professor of Physics, SRM University – AP, as a co-author, in International Journal of Energy Research, having Impact Factor of 5.164.

In this work, the research group investigated the origin of high catalytic activity of oxidic-N configuration in nitrogen-doped CNT and graphene heterostructure using density functional theory (DFT). We have plotted the free energy profile of the oxygen reduction reaction (ORR) to estimate the thermodynamic overpotential and catalytic performance of the respective active sites. The overpotential is related to the quantifying parameter ∆GOH (with R2 = 0.98) and the π electron density at the Fermi level, defined as an electronic descriptor, which is highly correlated with the ∆GOH with R2 value 0.96. For various N doped configurations, we correlated the ∆GOH values with π electron density at the Fermi level and found that the carbon site adjacent to the oxide-N configuration is a more prominent site for ORR. Further, we show that the oxidic-N configuration in the heterostructure of graphene and CNT is the ideal configuration, which gives a lower overpotential of 0.54 eV for ORR on adjacent carbon sites. Therefore, the charge transfer occurs from underneath CNT to graphene and increases the value of π electron density at the Fermi level which leads to the higher catalytic performance of the active site.

In the early 20th century, fuel cells were invented and their global impact has not reached up to its regular commercialization when compared with battery technology. The fuel cell device could be a powerful technique to generate electricity for large energy demand without greenhouse gas emissions. However, other major hurdles in the commercialization of fuel cell devices are the cost of platinum (as a catalyst), its poisoning and stability. Recently, carbon-based materials such as graphene, carbon nanotubes and activated carbon have been evolved as metal-free low-cost catalysts due to their (i) high abundance/yield (ii) reactivity towards oxygen just by introducing impurities like heteroatoms or other metals. However, identifying an efficient design principle to search optimal doping configurations in various carbon systems is a grand challenge for researchers.

This work is done in collaboration with Research Institute, SRM Institute of Science & Technology, Kattankulathur-603203, Chennai (India).

In future, the study aims to propose the effective design principle for various doped carbon systems as a catalyst to identify the optimal active sites and configurations for ORR. The role of π orbital in carbon systems such as graphene, graphene nanoribbons, carbon nanotube, etc is very important and can be a general electronic descriptor to define catalytic activity. Also, π electron descriptors and machine learning algorithms based combined approach can boost the search for ideal carbon catalyst for ORR with low DFT cost.
