Carbon dots (CD) are zero dimensional metal free tiny carbon nanoparticles containing sp2 carbon core and sp3 carbon outer surface. Very few CDs show enhanced laser absorption at NIR region which equip CD as a therapeutic agent. CD can perform as a photosensitizer, can induce hyperthermia which deplete growth of cancer, can be a carrier of photosensitizer and drug molecules due to compatible surface functionalization. On other hand, the advantages of mesoporous silica or hydrogel or carbonace...
Biofilms formed by various microbial communities are the main reason for the microbiologically induced corrosion of structural materials in the cooling tower systems of many industries. Plant extracts have been successfully used as natural corrosion inhibitors. Therefore, this study aims to develop green and natural inhibitors using plant extracts for controlling the biofilm formation in cooling water systems. A total of 45 bacterial strains have been isolated from Koel River water which is u...
Path planning with obstacle avoidance is crucial for navigating an Autonomous Underwater Vehicle (AUV) in an unknown and obstacle-rich three-dimensional space. Many studies have been conducted to develop a controller that can effectively navigate through an obstacle-rich environment for a mobile robot in a two-dimensional terrain. However, the trajectory planning of AUVs in a three-dimensional environment is still challenging. This paper aims to develop an optimized obstacle-free path in a th...
Advances in intelligent control technologies and remote sensing have opened up a whole new world of underwater autonomy. A number of research issues must first be investigated in simulation and experimental platforms to build competent remotely operated underwater robots for subsea environments. Underwater (Remotely Operated Vehicles) ROVs can improve their exploration and navigation efficiency by applying the Social Spider Optimization Algorithm (SSOA). Through the utilization of social spid...
Prediction of structure performance under seismic excitation and seismic damage after the seismic event plays a vital role in life safety and economics. These predictions are useful to the government and other private companies for preparing an effective methodology to be followed after seismic events, efficient retrofitting and rehabilitation to extend the durability of existing structures, insurance estimates, decision-making in disaster risk reduction, and others. The main objective of thi...
Differential expression of genes involved in cellular homeostasis is a collaborative outcome of coordination between molecular signal transduction, transcription factors and DNA and histone modification enzymes (Manna et al., 2023). Evidences are accumulating in favor of mechanotransduction induced chromatin modification and gene expression (Mishra et al., 2024). In response to specific signals, transcription factors and chromatin modifiers jointly dominate the expression/repression of genes....
As a green and sustainable means of transportation, electric vehicles (EVs) have attracted a lot of interest. The Li- Ion batteries, which store and transmit electrical energy to power the vehicle's propulsion system, are essential to the effective operation of EVs. For a battery to last longer, have a greater driving range, and be reliable, effective battery management, including charging and discharging procedures, is essential. This abstract offers a summary of the key elements of employin...
This study aims to assess the feasibility of various energy saving strategies for an existing district cooling system (DCS) that works on vapour compression chillers with a total of 680 TR capacity, located inside the campus of the academic institute, NIT Rourkela. The DCS supplies chilled water for cooling to multiple buildings of the institute. To improve the performance of this existing district cooling system, five alternative energy saving scenarios are considered along with the base cas...
Supramolecular polymers (SPs) represent a non-covalent alternative to traditional covalent polymers, involving the linkage of small molecular monomers through directional and reversible non-covalent interactions such as H-bonding and metal-ligand interactions.1 This presentation delves into the light-induced dynamic control of SP foldability, drawing inspiration from protein foldability-unfolding and light-induced ring opening supramolecular polymerization.2 The thoughtful design of monomers ...
In this paper focuses on the mobile robot's direction and control using Jellyfish search algorithm technique. The robot uses various sensors like front, left, right sensors to map the surroundings and the environments during this Jellyfish algorithm technique. This sensory data, for command of a robot, while navigating from starting position to destination position various obstacles at different positions are negotiated. A flexible Mini RC Mecanum Wheel Robot has been utilized for experimenta...
photocatalysis and photovoltaics because of their efficient ferroelectric polarization-driven carrier separation which in principle can lead to better photocatalytic activity compared to conventional semiconducting oxides. However, the efficiency reported so far for conventional ferroelectrics is still too low to be considered for practical application due to the wide band gap (>3eV) of these materials. The invention of visible light absorbing semiconducting ferroelectric oxide (1-x)KNbO3 -x(...
In this article, we report the synthesis and structural characterization of polycrystalline NixNbSe2 (x = 0, 0.05, 0.1, 0.15, 0.2, 0.25) and single crystals of NixNbSe2 (x = 0.14, and 0.25). The intercalation limit of Ni in NbSe2 is found to be 25 mole%, above which NiSe remains as an impurity phase. Single crystal diffraction studies show two distinct phase transitions with Ni intercalation in NixNbSe2.The phase evolves from a mixture phase (2H+4H) for the pristine NbSe2 to Ni intercalated 2...
Techno-economic assessment (TEA) is a comprehensive analysis tool to evaluate whether a proposed product is cost competitive to its conventional counterpart. It combines technological and economical aspects to evaluate technical feasibility and economic viability of the project. Economic indices viz., net present value, return on investment, internal rate of return, payback time, benefit/cost ratio, etc., are conventionally used to compare with business as usual scenario to determine the econ...
Advanced functional applications of materials often require unique microstructures and morphologies embedded in single or multi-phase nanostructures. For examples, lithium ion batteries (LIB) and supercapacitors, by far, the most promising energy storage devices that find application in numerous equipment of varying utility and dimension, require electrode materials with special microstructures for enhanced energy and power density. Hence, attention has shifted to the design of novel material...
Refractories are indispensable high-end composites; without these, no one can produce a single drop of steel to meet the 2.1 billion-ton demand globally. Continuous improvement seeks to alter steel chemistry, processing, and properties to serve society better and meet evolving refractory specifications. The steel sector has fixed different strategies to receive quality refractories. Thus, several factors are essential to consider in refractory design and failure analysis. Eventually, the nece...
Afghanistan grapples with multifaceted challenges concerning water availability and distribution, necessitating a comprehensive understanding of the current state of water resources.

In most of the signal source separation approaches, it is assumed that the number of signal sources is known, and hence, it cannot ensure satisfactory separation performance in real-world scenarios. The existing source counting methods lead to inaccurate estimation in the presence of noise, a limited number of samples, and the presence of outliers. Unlike other methods, this treatise formulates the problem in terms of supervised learning and obtained excellent performance even in challenging ...
