Effect of spin polarization on multifunctional physical properties of the quaternary Heusler alloys CrZCoSn (Z = Zr, Hf) for energy technologies: A comprehensive DFT study Kamal Kumar, Aparna Dixit, Abhishek K. Mishra, Soni Mishra, Ramesh Sharma Scientific Reports, 2026 In this study, we have performed first-principles calculations based on density functional theory (DFT), semi-classical Boltzmann theory, and full-potential linearized augmented plane wave (FP-LAPW) method with generalized gradient approximation (GGA) and Modified Becke–Johnson approach to investigate the structural, electrical, magnetic, optical, and thermoelectric properties of quaternary Heusler alloys CrZCoSn (Z=Zr, Hf). Our study reveals that both alloys are stable in the Type-1 (LiMgPdSn-type, space group F-43 m) structure, which is ferromagnetic in nature. The thermodynamic stability and ferromagnetic (FM) ground state of these HAs are confirmed by relative total energies and by calculated cohesive and formation energies, respectively. The existence of a band gap between the energy bands is elaborated with the hybridization of d-d orbitals among the constituent transition metals of HAs. The calculated magnetic moments of CrZrCoSn and CrHfCoSn alloys are 4.97 and 4.84 µ B, respectively, while the specific heat (C v ) of these alloys is 92.1 and 93.36 J/mol − 1 K, respectively. These alloys exhibit bulk modules of 117.43 and 118.73 GPa, respectively. Optical characteristics reveal that absorption of electromagnetic radiation takes place across the near UV and visible ranges of the spectrum. The static values of refractive index n(ω) for CrZrCoSn and CrHfCoSn HAs are 5.5 and 5.7, respectively. Results suggest that narrow bandgap (E g ), high ZT , and spin polarization make our HAs promising candidates for various spintronic, optoelectronic, and thermoelectric applications.
Carbon Nanotubes and their Applications in Cancer Treatments: A Comprehensive Review SONI Mishra, Kshitij Gurung, Abhishek K Mishra International Journal of Pharmaceutical Sciences and Nanotechnology, 2026 This study explores the molecular features of anti-cancer medications encapsulated within Single-Walled Carbon Nanotubes (SWCNTs) and Multi-Walled Carbon Nanotubes (MWCNTs). These carbon-based structures, known for their nanometer to millimeter-scale diameters, provide a unique platform for chemically modifying and attaching medicinally active compounds through strong covalent bonds.Utilizing their exceptional ability to pass through cellular barriers, combined with biocompatibility and targeting precision, carbon nanotubes have become promising carriers for delivering therapeutic agents to cancer cells. In this review, we examine the varied applications of carbon nanotubes in cancer research, emphasizing their role in studying pharmacokinetics, cytotoxicity, cell viability, and drug delivery mechanisms. Notably, carbon nanotubes have played a key role in studies involving the administration of various anti-cancer drugs such as paclitaxel, doxorubicin, and short-interfering RNA (siRNA). They also demonstrate proficiency in targeting magnetic lymph nodes, highlighting their versatility in therapeutic delivery systems. Additionally, carbon nanotubes facilitate the transport of a broad range of biologically active molecules, including peptides, nucleic acids, and proteins, to specific organs and cellular targets. Particularly, using carbon nanotubes as carriers for chemotherapy agents represents a burgeoning area of research with significant implications in nanobiotechnology and nanomedicine. This paper highlights the increasing effectiveness of carbon nanotubes as highly efficient nano-carriers for delivering biomolecules and drugs to the body, emphasizing their important role in advancing cancer therapy.
Computational investigation of the molecular structure and spectral properties of mesoridazine Soni Mishra, Abhishek K. Mishra Next Materials, 2026 This research examines the structural and spectroscopic properties of Phenothiazine derivatives, with a primary focus on the Mesoridazine (MDZ) molecule. As a phenothiazine derivative, MDZ has demonstrated remarkable biological activity against the main protease (Mpro) of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), making it a molecule of significant pharmacological interest. Also known as Serentil or TPS-23, MDZ is an organic compound in the phenothiazine class and has been widely used in treating schizophrenia, behavioral disorders, psychoneurotic disorders, and chronic alcoholism. In this study, the structural dynamics of MDZ have been analyzed using Density Functional Theory (DFT) calculations. The vibrational analysis based on DFT offers insights into molecular stability, electronic transitions, and structural changes.
Thermal Impact of Chronic Exposure to High-Frequency Non-ionizing EM Radiation on Avian Skin: A Theoretical Approach R Choudhary, V Kumar, S Mishra Indian Journal of Pure and Applied Physics, 2025 The manuscript reveals that the high-frequency electromagnetic radiations emitted from transmission towers affect birds' health. As the number of mobile phones is increasing rapidly, this radiation is present almost everywhere in the environment. This study uses a theoretical model based on Maxwell's equations to evaluate the thermal effects of electromagnetic radiation (EMR) of 3.5 GHz to 5.5 GHz frequency on avian skin. When birds fly from 1 to 10 m around a mobile phone tower, the electric field intensity is decreased by 90%. The results of the Specific Absorption Rate (SAR) inside the skin of avian show that its value is directly proportional to the frequency of the incident electromagnetic wave. The change in temperature in the skin tissue is calculated for the electromagnetic wave exposure duration of 1 to 15 min. At a frequency of 5.5 GHz and 1 m from a transmission source, the SAR reached 27.65 W/kg, and the skin temperature increased by up to 7.11°C after 15 min of exposure, indicating significant bioeffects. This study aids in the protection of birds by evaluating the thermal effects of electromagnetic radiation exposure and contributes to establishing safer exposure limits.
Bioeffects of EM Radiation on Human Skin Health: A Theoretical SAR Analysis Rockey Choudhary, Vijay Kumar, Soni Mishra Journal of Public Health and Pharmacy, 2025 Introduction: In this modern era, electromagnetic waves are playing a crucial role in our lives. An electric field is generated around the source of electromagnetic waves like mobile phone transmission towers, radio towers, TV towers, etc., which affects human beings living around them. The sources are increasing as we are regularly using devices that emit EM waves. Methods: to study the effects of non-ionizing EM radiation on the skin of human being, the electric field around the transmiison tower is calculated. When this external electric field incident on the body of human being, it penetrates inside the skin of human being. The penetrated electric field is calculated at different depth inside the skin. With the help of this penetrated electric field, the specific absorption rate inside the skin is also calculated for various height of transmission tower. The impact of non-ionizing EM radiation on the skin is predominantly associated with thermal effects. The extent of these effects depends on the intensity, duration, and proximity of the exposure.Results: In this manuscript, the specific absorption rate (SAR) is calculated inside the skin at the variable depth of the epidermis layer of human beings. The transmission towers of EM waves are taken at different heights. It is observed that the tower that has the minimum height produces more electric field inside the skin as compared to the longer-height tower.Conclusion: The amount of energy absorption by the tissues of the skin is higher for the transmission tower of 50 m height. The energy absorption by the tissues may become harmful for the health of the skin.
Ultra-selective hydrogen sensors based on CuO - ZnO hetero-structures grown by surface conversion Barnika Chakraborty, Dinu Litra, Abhishek Kumar Mishra, Cristian Lupan, Rajat Nagpal, Soni Mishra, Haoyi Qiu, Serghei Railean, Oleg Lupan, Nora H. de Leeuw, Rainer Adelung, Leonard Siebert Journal of Alloys and Compounds, 2024 Synergistic effects of mixed oxides have the potential to improve sensing performances of environmental, domestic and industrial monitoring devices. However, mixed oxides often come in the form of separate particles and are thus addressed separately by the environment, instead of capitalizing on the interface between the metal oxides. This paper describes a new core@shell gas sensing material of tetrapodal zinc oxide with a surface coating of crystalline copper oxide(t-ZnO@CuO). The special surface conversion strategy yields a unique, self-assembled and pinhole-free coating of CuO nanoplatelets. The morphologies, structural, chemical and gas sensing properties of the heterostructure were investigated. To evaluate the sensing properties of the heterostructure, t-ZnO@CuO was fabricated as nanosensors, consisting of one core-shell rod of CuO-coated crystalline ZnO. The single core@shell rod showed high selectivity towards hydrogen already at comparatively low operation temperatures of 150 °C. Computational calculations based on the density functional theory (DFT) have been carried out to understand the interaction of the H2 gas molecule with the surface of the CuO nanostructures. The surface conversion was done wet chemically and is a novel method for generating heterostructures that can be potentially transferred to heterojunctions with unique properties for chemosensors.
Drugs, drug-biomolecule interactions, and drugs delivery systems: Quantum chemical approaches Soni Mishra, Abhishek Kumar Mishra Computational Studies from Molecules to Materials, 2024 Quantum chemical calculations play a crucial role in the field of drugs and drug delivery systems, providing valuable insights into the molecular properties, interactions, and behavior of drugs at the atomic and subatomic levels. These help in the discovery and design of new drugs, and, through electronic structure calculations, one can predict their stability, reactivity, and binding affinity to target proteins. This information is vital for optimizing drug candidates and predicting their pharmacological activity. These calculations have also been used extensively to model drug molecules and their interactions with biological targets inasmuch as a detailed understanding of the structure-activity relationships is helpful in the prediction of the behavior of drugs in different environments and optimizing their efficacy. Quantum chemical calculations can also model the design of drug delivery systems, such as liposomes or nanoparticles, by optimizing their properties for efficient drug release and targeting. Here, computational chemistry can be broadly described as the endeavor to simulate chemical and biochemical phenomena (including structure, properties, reactivity, etc.) using computer-based methods. In this chapter, we discuss first the importance of nanoparticles in drug delivery systems, followed by a discussion of our recent work on quantum chemical calculations of a few drug molecules, lipids, and CNTs-based drug delivery systems.
