Purpose: Nanosized honeycomb-configured materials are used in modern technology, thermal science and chemical engineering due to their high ultra thermic relevance. This study aims to scrutinize the heat transmission features of magnetohydrodynamic (MHD) honeycomb-structured graphene nanofluid flow within two squeezed parallel plates under Joule dissipation and solar thermal radiation impacts. Design/methodology/approach: Mass, energy and momentum preservation laws are assumed to find the mathematical model. A set of unified ordinary differential equations with nonlinear behavior is used to express the correlated partial differential equations of the established models, adopting a reasonable similarity adjustment. An approximate convergent numerical solution to these equations is evaluated by the shooting scheme with the Runge–Kutta–Fehlberg (RKF45) technique. Findings: The impression of pertinent evolving parameters on the temperature, fluid velocity, entropy generation, skin friction coefficients and the heat transference rate is explored. Further, the significance of the irreversibility nature of heat transfer due to evolving flow parameters are evaluated. It is noted that the heat transference rate performance is improved due to the imposition of the allied magnetic field, Joule dissipation, heat absorption, squeezing and thermal buoyancy parameters. The entropy generation upsurges due to rising magnetic field strength while its intensification is declined by enhancing the porosity parameter. Originality/value: The uniqueness of this research work is the numerical evaluation of MHD honeycomb-structured graphene nanofluid flow within two squeezed parallel plates under Joule dissipation and solar thermal radiation impacts. Furthermore, regression models are devised to forecast the correlation between the rate of thermal heat transmission and persistent flow parameters. [ABSTRACT FROM AUTHOR]

- Abstract
In an effort to replace the use of SF6gas in high-voltage equipment, research has been conducted on more environmentally favorable alternative gases to this potent greenhouse gas. In the present study, the SO2–CO2gas mixture is selected among all alternatives, including SF6, with the requirement to meet features such as reducing ozone depletion potential, global warming potential, being chemically stable, non-toxic, and having a having a boiling point of − 15 °C. Furthermore, aspects like material compatibility-based electrical properties such as dielectric constant, cost, and environmental impacts were taken into consideration. Consequently, a gas mixture of 30% SO2and 70% CO2was finally chosen. In this paper, power frequency breakdown voltage was experimentally measured under a quasi-uniform field while varying gas pressure from 0.2 to 2 bar for 5 mm and 10 mm of electrode gap, respectively. Subsequently, a synergistic coefficient is calculated for this mixture. The obtained results of PFBDV and synergism coefficient for a 30% SO2and 70% CO2gas mixture were compared with mixtures like SF6/N2, CF3I/N2/CO2, C3F8/CO2, C4F7N/CO2, R12/air/N2, and c-C4F8O/CO2/N2. Consequently, it emerged that the insulating characteristics of 30% SO2and 70% CO2are better than most of the other alternatives, along with considerable advantages like negligible environmental impact, low cost, better material compatibility, and low toxicity. These systematic investigations predominantly indicate that a gas mixture containing 30% SO2and 70% CO2can be employed as a substitute for SF6in high-voltage gas-insulated equipment.

- Abstract
This article presents a robust controller for a single-phase single-stage photovoltaic systems (PVSs) converter connected to the grid. A high-efficiency single-phase single-stage converters are prone to double-frequency oscillations and dc-link voltage fluctuations when connected to a PVS. It introduces phase shift and injects harmonics in the grid current. To address this issue, a robust dc-link voltage controller is proposed. It can achieve a fast transient response with lesser overshoot under power intermittency and grid-side disturbances. A filter is employed to reduce the impact of switching frequency; however, a Lyapunov-based inner loop current controller with an active damping method minimizes the effect of resonance and achieves system stability. The proposed composite controller guarantees the system’s robustness against grid disturbances and parameter uncertainties. In addition, it eliminates the effect of phase shift and achieves zero steady-state error. Both the simulation and experimental results are presented to demonstrate the performance of the controller.

- Abstract
The critical breakdown electric field strength (DS) of SO2gas is evaluated for arc quenching phase wherein high rates recovery of insulating strength (RRIS) is essentially required to stop the restrike of arc voltage for high-voltage switchgears. In this phase, the temperatures can surpass 4000 K and pressures can approach 10 Bar. These extreme conditions alter the initial synthesis of gas and subsequently affects DS of gas. The DS of gas is estimated several steps. In first step, gas composition is obtained for different temperatures and pressures using Gibbs minimum free energy criterial under localized chemical and thermodynamics equilibrium (LCE and LTE). In second step, the Townsend coefficients are calculated by solving the Boltzmann Transport Equation (BTE) through the adoption of two-term approximations. Finally, Townsend criteria are applied to determine the dielectric strength for given electric field. As per the findings, the DS of SO2gas at room temperature is 263 Td; however, at 4000 K and 10 bar, DS lowers to 163 Td which is better that SF6and CO2gas. Therefore, replacing the SF6gas with SO2would enhance the dielectric characteristics above 2000 K, regardless of the reduced critical dielectric strength at room temperature when compared to SF6, Air, and CO2. This shows that SO2might be a good replacement for unitary gas and as a mixture component coupled with CO2, N2, and other non-greenhouse gases for practical applications in high-voltage circuit breakers used as a quenching of arc and insulating medium. The experiment that was undertaken suggests that using SO2could improve switching equipment’s ability to withstand disruptions. The calculated results showed an impressive agreement with the observational data.

- Abstract
A PV three-phase grid following inverter (GFI) with LCL filters can reduce current harmonics and deliver active power to the grid. Controlling such higher-order systems is challenging due to system uncertainties, grid voltage variations, and filter resonance. Active disturbance rejection control (ADRC) provides resilience to these uncertainties and a prompt response to disturbances. A linear extended state observer and a phase-locked loop observer are integrated into the ADRC structure to optimize tracking performance. The proposed controller uses a structured inner and outer closed-loop ADRC that takes into account process delays and extended state observer dynamics. The GFI can operate under variable grid voltage frequencies or even deviations in frequency caused by grid failure, and is able to meet these challenges as part of the design process and the synchronization approach. Both simulation and experimental results are given to validate the dual ADRC-based methods for an 8 kW laboratory prototype PV-GFI system.

- Abstract
The main goal of this presentation is to scrutinize the flow behavior of transient hydromagnetic Ti6Al4V-H2O-based nanofluid flow within a symmetric channel bounding a uniform porous medium with induced magnetic field and Hall current effects. The nanofluid is assumed to be partially ionized and its flow is influenced due to the presence of a strong transverse applied magnetic field domain. Due to this reason, induced magnetic field and Hall current impacts are focused in this study. The right surface of the channel is considered to be magnetized and oscillating vertically while the left surface is non-magnetized and stationary. The flow model is transformed to a similar model by the use of dimensionless transformations and leading resulting equations are solved analytically with the aid of variable separable method. The results are demonstrated with the assistance of Mathematica software and also validated with the existing results in the literature. This study is significant in analyzing the flow nature of highly electrically conducting nanofluids. An important flow characteristic observed from this study is that by increasing the volumetric concentration of nanoparticles in the fluid, the induced magnetic field is increased due to the rise in electrical conductivity of the fluid. Furthermore, the Hall current and magnetic diffusion brings a significant decrement in induced magnetic field along the main flow.

Yang, Hyun-Min, Singh, Jitendra Kumar, and Jang, Hyun-O.
- Abstract
In the present studies, ginger powder has been used as an eco-friendly admixture for the cement mortar. Different amounts i.e. 0 wt% (M1), 0.10 wt% (M2), 0.25 wt% (M3) and 0.50 wt% (M4) ginger powder was mixed in the cement mortar (M1) and assessed the durability. The ginger powder with 0.50 wt% (M4) improves the compressive strength by 17 % owing to the water reducing capability, which enhance the hydration reaction and fill the pore matrix of the cement mortar. The active ingredient of ginger powder i.e. shogaol adsorbs on the steel rebar surface through leaching mechanism by interaction of oxygen (O) and п-electrons with iron (Fe) and provide corrosion protection at longer duration of continuous immersion in 3.5 wt% NaCl solution. Following 173 d in a 3.5 wt% NaCl solution, the M4 sample exhibits 82.10 % corrosion inhibition efficiency. Therefore, it is suggested that ginger powder could be a potential eco-friendly admixture to be used in construction industries to get high durability performance in the coastal areas.

Shivaprasad, Kadepalli Nagendra, Yang, Hyun-Min, and Singh, Jitendra Kumar
- Abstract
The cement industries as binder materials, produces 1.6 billion metric tons’ carbon dioxide (CO2) in 2022 and cause depletion in ozone layer. The cement is being used in modern construction and cause the environmental impact. Therefore, there is a quest for a sustainable alternative binder to reduce the CO2emission from the conventional cement production and their effective disposal methods in construction and demolished (C&D) waste is paramount. This article delves into the production of recycled cement by leveraging various methods such as mechanical activation, chemical activation, and heat treatment of C&D waste, ultimately contributing to the carbon neutrality. A comparison with traditional cement production sheds light on energy consumption, CO2emissions, and resource utilization. The recycled cement displays increased water demand, accelerated early setting, extended final setting time, and reduced compressive strength. However, when used solely as a cementitious matrix, recycled cement can readily achieve up to 30 MPa in 28 days. Utilising recycled cement in concrete applications demonstrates its efficacy in the construction industry. The insights provided herein offer a holistic understanding of the production processes, properties, and applications of recycled cement, reinforcing its potential as a viable and environmentally friendly alternative in the realm of construction materials.

- Abstract
Abstract: The perovskite solar cell technologies are the hope of satisfying the huge demand of tomorrow’s energy requirements. The inorganic, organic and mixed perovskite materials are the backbone of modern solar cells. The energy band gap and refractive index of perovskites help in selecting proper materials for solar cell, solid-state lighting and lasing applications. In this paper, various perovskite materials and different energy band gap–refractive index relations have been studied. A simple empirical relationship between energy gap ‘E
g ’ and refractive index ‘n’ for perovskites has been developed and proposed. Using this relationship, refractive indices of 33 different perovskites have been calculated and compared with their reported values. Also, the refractive indexes of about 140 new perovskites have been predicted and reported probably for the first time. The researchers interested in refractive index calculation may use the proposed relation and need not to worry for complex experimental setup. Graphic abstract:- Published

Singh, Jitendra Kumar, Banerjee, Gautam, Singh, Arvind Kumar, and Vishwakarma, Rajendra Kumar
- Abstract
Intrinsic safety is the safest technique to prevent explosions that might occur in underground coal mines and process industries in the presence of explosive atmosphere. Designing of intrinsically safe equipment require keeping its energy below the minimum ignition energy of the explosive gases. In this work, three empirical relations based on standard IS/IEC 60079-11 have been proposed for the first time and used in the calculation of short circuit current (I), permitted capacitance (C) and inductance (L) of intrinsically safe circuits designed for gas groups IIA, IIB, IIC and I. The calculated values are compared with the available experimental and reported values. A fairly good agreement has been obtained between them. The designers of intrinsically safe circuits can use these relations as a very handy tool especially for the explosive gas atmosphere of underground coal mines and process industries. This research will contribute to the reduction of fatal accidents due to explosive gases. [Received: August 20, 2017; Accepted: March 11, 2018]

- Abstract
Industries dealing with explosive gases and combustible dusts in processing or production are always at higher risk of gas or dust explosion. Purified terephthalic acid (PTA) plant of Indian Oil Corporation Ltd. (IOCL), Panipat, India has similar risk of dust explosion hazard, since PTA is a combustible substance in the form of dust or layer. To load, unload and transport the PTA bags in the plant, special forklift trucks are required. A prototype forklift truck for combustible dust atmosphere was developed in collaboration with M/s Action Construction Equipment Ltd. (ACE), Palwal, India. The electrical components with dust ignition protected design have been manufactured by ACE in consultation with CSIR-CIMFR, Dhanbad, India. All other possible sources of ignition are identified and suitable components/parts of forklift are used for hazardous atmosphere. This paper presents the design requirements of a dust ignition protected and battery operated forklift truck for safe use in zone 22 combustible dust atmosphere of the plant.

Singh, Jitendra Kumar, Seth, Gauri Shenkar, and Begum, S. Ghousia
- Abstract
In the present research study a mathematical analysis has been presented for unsteady MHD natural convective flow of a rotating fluid over an infinite vertical plate immersed in a fluid saturated porous medium with oscillating free-stream. The effects of Hall and ion-slip currents also considered on the fluid flow. The unsteady MHD flow over the vertical plate is induced due to thermal and concentration buoyancy forces and oscillatory movement of the free-stream. The partial differential equations governing the motion for the fluid flow are solved analytically. The effects of various pertinent flow parameters on the fluid velocity, fluid temperature and species concentration are presented in graphical form whereas that on skin friction and rate of heat and mass transfer at the plate are presented in tabular form. An interesting observation recorded from the present analysis that there appears reversal flow in the secondary flow direction due to presence of thermal and/or concentration buoyancy forces. However, in the absence of both reversals flow does not exist in the secondary flow direction. It is also noted that the thickness of momentum boundary layer decreases with rise in frequency of oscillations of the free-stream.

- Abstract
In this study, we demonstrate development of p-Cu2O thin films through cathodic electrodeposition technique at constant current of 0.1 mA/cm2on Cu, Al, and indium tin oxide (ITO) substrates from basic CuSO4solution containing Triton X-100 as the surfactant at 30–35 °C. The optical and morphological characterizations of the semiconductors have been carried out using UV–vis spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and Raman spectroscopy. The band gap energy of ∼2.1 eV is recorded, whereas SEM reveals that the surface morphology is covered with Cu2O semiconductors. XRD analyses confirm that with change in substrate, the size of Cu2O “cubic” crystallites decreases from ITO to Al to Cu substrates. Photoelectrochemical characterizations under dark and illuminated conditions have been carried out through linear sweep voltammetry, chronoamperometry and electrochemical impedance spectroscopic analysis. The photoelectrochemical reduction of water (H2O → H2) in pH 4.9 aqueous solutions over the different substrates vary in the order of Cu > Al > ITO. The highest current of 4.6 mA/cm2has been recorded over the Cu substrate even at a low illumination of 35 mW/cm2, which is significantly higher than the values (2.4 mA/cm2on Au coated FTO or 4.07 mA/cm2on Cu foil substrate at an illumination of 100 mW/cm2) reported in literature.

Mandal, Soumen, Ishak, Shafiq, Singh, Jitendra Kumar, Lee, Dong-Eun, and Park, Taejoon
- Abstract
The present study has been focused on the synthesis of silica encapsulated paraffin phase change materials and its application in cement-based systems. One-pot in-situ hydrolysis of tetraethyl orthosilicate as silica precursor and subsequent polycondensation have successfully encapsulated the paraffin droplets into nano-sized capsules of phase change materials (PCMs). The fabricated nanoencapsulated PCMs (NEPCMs) possess distinct core-shell structures with spherical geometry. Encapsulation ratio and encapsulation efficiency have been accomplished up to 92.9 and 90.24% with the latent heats of melting and solidification of 173.79 and 158.93 J/g, respectively. Calorimetry studies of the fabricated NEPCMs with ordinary Portland cement (OPC) have demonstrated 11% temperature reduction during the evolution of the heats of hydration, with the addition of only 3% NEPCMs. The synthesized PCMs are found to perform as high thermal energy storage materials with the capability of congruent heat storage and release without affecting their structure and geometry, therefore, can be considered as reliable and durable PCMs for concrete and building materials. The use of these NEPCMs can control the maximum temperature rise due to heat of hydration and therefore reducing the defects and cracks formation inside the mass concrete structures.

24. Thermo-diffusion impacts on the flow of an elastico-viscous fluid over an inclined heated plane with magnetized wall

Singh, Jitendra Kumar and Seth, Gauri Shenker
- Abstract
The focus is in this article is to scrutinize the simultaneous significances of magnetic diffusion, thermo-diffusion and angular location on the hydromagnetic flow of an elastico-viscous fluid over an inclined heated plane with magnetized wall. The flow medium is considered to be uniformly permeable (Darcy-Brinkman porous medium) and the flow of the fluid is considerably affected due to the appearance of a strong magnetic field in the direction normal to the flow surface. The significances of Hall current, induced magnetic field and Coriolis force on flow nature is also included in the study. The leading non-dimensionalized equations are explored by regular perturbation analysis. Ultimately, the expressions for velocity field, induced magnetic field, temperature and concentration are obtained. We further derived the surface skin friction, surface current density, heat and mass fluxes. The computation of results is performed with the aid of Mathematica software and results are presented in graphical and tabular forms for distinct flow impacting parameters. Numerical simulation explores that mass diffusion factor brings growth in the fluid velocity, temperature and normal induced magnetic field while it reduces the main induced magnetic field. Magnetic diffusion develops the primary flow and primary induced magnetic field and lessens the normal flow and normal induced magnetic field. Inclination angle of the heated plane upgrades primary induced magnetic field while downgrading normal induced magnetic field.
