    Abstract Pyrolysis is a major process in producing biochar sorbent from agriculture waste. The adsorption capability of biosorbents is greatly affected by the pyrolysis conditions. In this study, the adsorption interaction of atrazine and hydrochloric acid (HCl) modified corn cob bio-waste sorbents (CBS) was investigated as the function of the pyrolysis conditions, which are pyrolysis temperatures (400–600 °C) and residence times (2 to 6 h). The CBS characteristics, adsorption behaviour, and kinetics were determined. Pyrolysis conditions affected the specific surface area (SSA) and the total pore volume (TPV). The increasing ability of atrazine adsorption of CBS depended on SSA and TPV. The chemical interaction between atrazine and CBS was dominated by the H-bonding interaction. The maximum adsorption capacity of CBS was in the range of 11.31–19.58 mg/g. The sorption energy range of the CBS and atrazine interaction was 22.13–38.05 kJ/mol. The pseudo-second-order-model was the best fit describing the adsorption kinetics of atrazine on CBS. The rate-limiting step from the intra particle diffusion model has a high tendency to be the film diffusion. From this work, CBS has a high efficiency in atrazine adsorption and it can be an effective material with great potential for pollutant removal.

    Abstract Office workers are at high risk for many chronic diseases, lowering their health-related quality of life (HRQOL). This systematic review and meta-analysis aimed to summarize the effects of physical exercise on HRQOL in office workers with and without health problems using data obtained from randomized controlled trials (RCTs), quasi-experimental, and observational studies. We searched PubMed, Web of Science, Scopus, Cochrane Library, and several grey literature databases, and identified 26 relevant studies for the synthesis. Overall, physical exercise significantly improved general (standardized mean difference (SMD) = 1.05; 95% confidence interval (CI): 0.66 to 1.44) and mental (SMD = 0.42; 95% CI: 0.19 to 0.66) HRQOL in office workers. Compared with healthy office workers, unhealthy office workers experienced greater improvements in general (unhealthy, SMD = 2.76; 95% CI: 1.63 to 3.89; healthy, SMD = 0.23; 95% CI: -0.09 to 0.56) and physical (unhealthy, SMD = 0.38; 95% CI: 0.17 to 0.58; healthy, SMD = -0.20; 95% CI: -0.51 to 0.11) HRQOL. Unsupervised physical exercise significantly improved general and mental HRQOL, while directly supervised physical exercise significantly improved only general HRQOL. Although physical exercise, especially unsupervised physical exercise, should be encouraged to improve HRQOL in office workers, detailed recommendations could not be made because of the diverse exercise types with different intensities. Therefore, further studies are needed to determine the optimal exercise for office workers with different health conditions.

    Abstract One of the most enticing approaches to environmental restoration and energy conversion is photocatalysis powered by solar light. Traditional photocatalysts have limited practical uses due to inadequate light absorption, charge separation, and unknown reaction mechanisms. Discovering new visible-light photocatalysts and investigating their modification is crucial in photocatalysis. Bi-based photocatalytic nanomaterials have gotten much interest as they exhibit distinctive geometric shapes, flexible electronic structures, and good photocatalytic performance under visible light. They can be employed as stand-alone photocatalysts for pollution control and energy production, but they do not have optimum efficacy. As a result, their photocatalytic effectiveness has been significantly improved in the recent decades. Numerous newly created concepts and methodologies have brought significant progress in defining the fundamental features of photocatalysts, upgrading the photocatalytic ability, and understanding essential reactions of the photocatalytic process. This paper provides insights into the characteristics of Bi-based photocatalysts, making them a promising future nanomaterial for environmental remediation. The current review discusses the fabrication techniques and enhancement in Bi-based semiconductor photocatalysts. Various environmental applications, such as H

    Abstract Two-dimensional transition metal dichalcogenides (2D-TMDCs) with various physical characteristics have attracted significant interest from the scientific and industrial worlds in the years following Moore's law. The p-n junction is one of the earliest electrical components to be utilized in electronics and optoelectronics, and modern research on 2D materials has renewed interest in it. In this regard, device preparation and application have evolved substantially in this decade. 2D TMDCs provide unprecedented flexibility in the construction of innovative p-n junction device designs, which is not achievable with traditional bulk semiconductors. It has been investigated using 2D TMDCs for various junctions, including homojunctions, heterojunctions, P-I-N junctions, and broken gap junctions. To achieve high-performance p-n junctions, several issues still need to be resolved, such as developing 2D TMDCs of superior quality, raising the rectification ratio and quantum efficiency, and successfully separating the photogenerated electron-hole pairs, among other things. This review comprehensively details the various 2D-based p-n junction geometries investigated with an emphasis on 2D junctions. We investigated the 2D p-n junctions utilized in current rectifiers and photodetectors. To make a comparison of various devices easier, important optoelectronic and electronic features are presented. We thoroughly assessed the review's prospects and challenges for this emerging field of study. This study will serve as a roadmap for more real-world photodetection technology applications.

    Abstract According to a resourceful survey, bimetallic selenides with their hierarchical nanostructures have gained widespread attention despite their enhanced electrical conductivity. Consequently, the incorporated morphology, structure, and constituent modulation of the foremost electrode endows it with a privileged trial for the transportation and diffusion of ions. The structural and morphological study agrees with the configuration of mono- and bimetallic selenides analytically. Herein, cobalt (Co) ions in their composite heterostructures find a fundamental role in the configuration of the nanostructure having fine conducting nature. Therefore, a nanosphere is merged arbitrarily to form a conductive network, which might ease charge transfer. Furthermore, the heterostructured NiSe₂@CoSe₂ electrode displayed an improved specific capacitance of 531 F g–¹ at a current density of 1 A g–¹, and an outstanding long-term durability of 99.88% was achieved over 5000 charge–discharge cycles. The nanostructure morphology and structure of the fabricated electrode predominantly stimulate its application in energy-related attributes because of large active sites, improved surface-to-volume ratio, and limited transport length of the ions. In addition, an assembled full cell NiSe₂@CoSe₂//AC with a paramount operating voltage of 1.5 V using 1 M KOH achieved an increased energy density of 41 Wh kg–¹ at a power density of 738 W kg–¹ with a retention of 99.86% over 5000 cycles. The highly assembled asymmetric device lights up a blue light-emitting diode (LED), demonstrating a voltage of 1.63 V. The existing protocol entails an excellent reference for various metal selenides for efficient storage appliances.

    Abstract Architecting a desirable and highly efficient nanocomposite for applications like adsorption, catalysis, etc. has always been a challenge. Metal Organic Framework (MOF)-based hierarchical composite has perceived popularity as an advanced adsorbent and catalyst. Hierarchically structured MOF material can be modulated to allow the surface interaction (external or internal) of MOF with the molecules of interest. They are well endowed with tunable functionality, high porosity, and increased surface area epitomizing mass transfer and mechanical stability of the fabricated nanostructure. Additionally, the anticipated optimization of nanocomposite can only be acquired by a thorough understanding of the synthesis techniques. This review starts with a brief introduction to MOF and the requirement for advanced nanocomposites after the setback faced by conventional MOF structures. Further, we discussed the background of MOF-based hierarchical composites followed by synthetic techniques including chemical and thermal treatment. It is important to rationally validate the successful nanocomposite fabrication by characterization techniques, an overview of challenges, and future perspectives associated with MOF-based hierarchically structured nanocomposite.

    Abstract Covalent organic frameworks (COFs) based on core@shell nanohybrids have recently received significant attention and have become one of the most promising strategies for improving the stability and catalytic activity of COFs. Compared with traditional core@shell, COF-based core@shell hybrids own remarkable advantages, including size-selective reactions, bifunctional catalysis, and integration of multiple functions. These properties could enhance the stability and recyclability, resistance to sintering, and maximize the electronic interaction between the core and the shell. The activity and selectivity of COF-based core@shell could be simultaneously improved by taking benefit of the existing synergy between the functional encapsulating shell and the covered core material. Considering that, we have highlighted various topological diagrams and the role of COFs in COF-based core@shell hybrid for activity and selectivity enhancement. This concept article provides all-inclusive advances in the design and catalytic applications of COF-based core@shell hybrids. Various synthetic techniques have been developed for the facile tailoring of functional core@shell hybrids, including novel seed growth, in-situ, layer-by-layer, and one-pot method. Importantly, charge dynamics and structure-performance relationships are investigated through different characterization techniques. Different COF-based core@shell hybrids with established synergistic interactions have been detailed, and their influence on stability and catalytic efficiency for various applications is explained and discussed in this contribution. A comprehensive discussion on the remaining challenges associated with COF-based core@shell nanoparticles and research directions has also been provided to deliver insightful ideas for additional future developments.

    Abstract Pesticides have been frequently used in agricultural fields. Due to the expeditious utilization of pesticides, their excessive usage has negative impacts on the natural environment and human health. This review discusses the successful implications of nanotechnology-based photocatalysis for the removal of environmental pesticide contaminants. Notably, various nanomaterials, including TiO₂, ZnO, Fe₂O₃, nanoscale zero-valent iron, nanocomposite-based materials, have been proposed and have played a progressively essential role in wastewater treatment. In addition, a detailed review of the crucial reaction condition factors, including water matrix, pH, light source, temperature, flow rate (retention time), initial concentration of pesticides, a dosage of photocatalyst, and radical scavengers, is also highlighted. Additionally, the degradation pathway of pesticide mineralization is also elucidated. Finally, the challenges of technologies and the future of nanotechnology-based photocatalysis toward the photo-degradation of pesticides are thoroughly discussed. It is expected that those innovative extraordinary photocatalysts will significantly enhance the performance of pesticides degradation in the coming years.

    Abstract Recently, the concept of green chemistry has emerged as a novel and efficient way for environmental remediation. Amongst several biomaterials, cellulose is the most widely utilized natural biopolymer and significant adsorbent due to its unique and exceptional characteristics such as biodegradability, biocompatibility, reproducibility, non-toxicity, cost-effectiveness, increased specific area, greater interaction between active sites and pollutants, and high adsorption capacity. On the other hand, photocatalysis, an advanced water purification technique accelerates chemical reactions in the presence of light. But, the photocatalysts are inherited with certain limitations like low surface area for adsorption, charge carriers’ recombination rate, etc. In this regard, the combination of cellulose with other photocatalysts typically results in adsorptional photocatalysis which improved porosity, surface area, and photocatalytic efficacy of photocatalysts. Cellulose serves as a support material and acts as an electron mediator that effectively enhanced charge carrier’s migration ability and decreases their recombination rate. Hence, the current review mainly focuses on the incorporation of cellulose materials with various photocatalysts to enhance their photocatalytic efficiency. Also, the review briefly discussed the structural properties and various types of cellulose biomaterials as well as various types of harmful dyes with their hazardous effects. Additionally, the photocatalytic efficacy of various metal-oxides, metal-sulfides, metal-free photocatalysts, and cellulose-supported photocatalysts was explored with mechanistic insights toward the photodegradation of toxic dyes.
