Congratulations to Prof. Tribeni Roy and his team for getting their work published in Carbon. 🎉   𝐓𝐢𝐭le: “A close-packed sphere model for characterising porous networks in atomistic simulations and its application in energy storage and conversion”.     Highlights: Hierarchical (micro, meso & macro) porosity in materials plays a crucial role in influencing the movement of ions which governs the energy and power density during energy storage and conversion. The extant available methods to characterise porosity across scales (nano to meso to macro) lacks rigour and accuracy. Having accurate assessment of the porosity in materials can unlock new designs of electrodes for energy efficient energy storage and conversion devices such as batteries, supercapacitors and fuel cells. Through this work, we report the systematic development of a method to fully characterise the carbon porous networks using a molecular dynamics simulation testbed. Our work entails modelling and simulation of porous carbon structures using quenched molecular dynamics (QMD) simulations using Gaussian Approximation potential (GAP) and benchmarking the results with prior literature. This modelling technique can reliably be used for quantitative characterisation of the interconnectivity in porous structures to study ionic movements and charge transfer mechanisms. A new parameter, namely nearest neighbour search (NNS) coefficient was introduced to quantify homogeneity and networking in the porous structures. NNS coefficient increased from 1.62 to 1.92 with decrease of the annealing temperature from 8000 K to 4000 K in carbon. The procedure outlined was although tested on porous carbon networks, but adaptable to study any other material system at multi-length scales.   Link: https://lnkd.in/g9s7UMnE 𝐀𝐮𝐭𝐡𝐨𝐫: Manikantan R Nair , Ayush Khaitan, Ayush Owhal, Inturi Ramesh Chandra, Sachin Belgamwar, Radha Raman Mishra, Saurav Goel, Tribeni Roy WeBPage: https://lnkd.in/gkfKFYNi     Birla Institute of Technology and Science, Pilani| BITS Pilani, Hyderabad Campus| Research & Innovation, BITS Pilani | Tribeni Roy | Sanket Goel | Surender Mohan | Vishwajeet Parihar | Arpita Sharma | Vijay Singh | Apurva Vunnava      

The Research & Innovation, BITS Pilani team is excited to share a new publication by Dr. Harikrishnan A R and other author published in Physics of Fluids. 🎉   𝐓𝐢𝐭le: Role of retraction dynamics in bouncing to pinning transition during drop impact on cold superhydrophobic surfaces   Highlights: The present study brings out the influence and relevance of retraction dynamics on bouncing to pinning transition of impacting drop on cold superhydrophobic surface. A theoretical framework has been proposed to predict the pinning to bouncing regimes for drop impact over subcooled superhydrophobic surfaces. The results of this study give engineers a path toward creating surfaces with anti-icing properties.   𝐃𝐎𝐈: https://lnkd.in/ghhbWdMN   Birla Institute of Technology and Science, Pilani | BITS Pilani, Hyderabad Campus| Research & Innovation, BITS Pilani| Dr. Harikrishnan A R | Sanket Goel | Surender Mohan | Vishwajeet Parihar | Arpita Sharma | Praloy Mondal | Apurva Vunnava | Dr. Radhika Vangala | Dr. Juhi Kumari | Navya Debbad

Congratulations to Prof. B. Harihara Venkataraman and his team for getting their work published in ECS Journal of Solid State Science and Technology. 🎉   𝐓𝐢𝐭le: Influence of the synthesis process on the physical property characteristics of BiFeO3 ceramics prepared by flux-based molten salt and solid-state reaction route: A comparative study”   Highlights:  This research article reports the influence of the solid-state reaction and molten-salt synthesis routes on the physical properties of the multiferroic bismuth ferrite (BiFeO3) compound exploited for capacitors and memory devices. The structural analysis reveals that the molten salt synthesis derived BiFeO3 ceramics have exhibited a pure-phase distorted rhombohedral perovskite structure at low temperatures (650℃) compared to the solid-state reaction method. The scanning electron micrograph illustrates the uniform distribution of spherical-shaped BiFeO3 grains. By altering the fabrication route, the calculated bandgap values of BiFeO3 were tuned within the range of (2.14 ± 0.02) to (2.05 ± 0.02) eV based on Tauc’s plot. The suppression of oxygen vacancies led to better dielectric characteristics at higher frequencies in the molten salt-prepared BiFeO3 nanoceramics. Also, the molten salt-derived BiFeO3 ceramics possessed a typical canted-antiferromagnetic loop with a higher MR value of ~2.73x10-2 emu/g. These observations suggest that fabrication techniques have a decisive effect on the phase formation kinetics and multiferroic properties of BiFeO3 ceramics.

I'm pleased to share that a recent work on Reinforcement Learning from APPCAIR, authored by Ashman Mehra, Divyanshu Singh; Raychoudhury, Vaskar; ARCHANA MATHUR; Saha, Snehanshu has been accepted for publication in a top tier journal!   IEEE T-ITS acceptance! The paper entitled: The Last Mile: A Novel, HotSpot Based Distributed Path-Sharing Network for Food Deliveries has been accepted in “IEEE Transactions on Intelligent Transportation Systems" (Q1, I.F: 9.95, h5-index: 165), This journal is ranked # 1 in All Transportation Research journals, within top 100 of all journals and conferences listed by Google Scholar and Nature Index! —Delivery of items from the producer to the consumer has experienced significant growth over the past decade and has been greatly fueled by the recent pandemic. Amazon Fresh, GrubHub, UberEats, Postmates, InstaCart, and DoorDash are rapidly growing and are sharing the same business model of consumer items or food delivery. Existing food delivery methods are sub-optimal because each delivery is individually optimized to go directly from the producer to the consumer via the shortest time path. We observe a significant scope for reducing the costs associated with completing deliveries under the current model. For this, we model our food delivery problem as a multi-objective optimization, where consumer satisfaction and delivery costs, both, need to be optimized. Taking inspiration from the success of ride-sharing in the taxi industry, we propose DeliverAI - a reinforcement learning-based path-sharing algorithm. Unlike previous attempts for path-sharing, DeliverAI can provide real-time, time efficient decision-making using a Reinforcement learning-enabled agent system. Our novel agent interaction scheme leverages path sharing among deliveries to reduce the total distance traveled while keeping the delivery completion time under check. We generate and test our methodology vigorously on a simulation setup using real data from the city of Chicago. Our results show that DeliverAI can reduce the delivery fleet size by 15%, the distance traveled by 16%, and 50% higher fleet utilization w.r.t point-to-point delivery systems.

The Research & Innovation team at BITS Pilani is excited to share a new publication by Nitish Kumar Gupta, Jaspreet Singh , Subhendu Sarkar published in Nanotechnology (Institute of Physics)🎉   𝐓𝐢𝐭le: A hybrid effective medium description for nanoporous gold films and thickness-mediated control of optical absorption Nanoporous gold films have emerged as an ideal substrate for rapid, quantitative detection of analytes with excellent specificity and high sensitivity. Our study investigates thickness-mediated compositional changes and their impact on scattering characteristics of thin nanoporous gold films fabricated through de-alloying process. Specifically, we observe thickness-induced morphological and structural changes across different fabricated samples from 25 to 100 nm in thickness. This results in substantial change in their optical scattering characteristics, which have been captured experimentally and explained by devising a hybrid theoretical model comprising Maxwell-Garnett & Bruggeman effective medium theories.
