Green synthesis; Indian medicinal plants; Nanoparticles; Phytochemicals; Reducing agents
Considering the exclusive environmental conditions and geological characteristics, Indian flora is extensive and rich in medicinal plants. From primeval times, plant parts and their metabolites have been widely explored for various practices including medicinal as well as culinary. The phytochemicals present in these plants are potential reducing agents for the bio-fabrication of these nanoparticles. The non-toxic nature and combination of the plant phytochemicals with precursor ions act as key aspects for synthesized nanoparticles. The present review highlights the potential applications of Inorganic nanoparticles synthesized from 148 traditionally used medicinal plants present in the Indian geographical region. In addition, parameters that influence the green synthesis of Inorganic nanoparticles such as the extraction methods, solvents used for extraction, the concentration of precursor and plant phytochemicals, pH, temperature, reaction time, and characterization techniques of the nanoparticles are discussed. Thus, the review provides information on the research that has been done in the area of green synthesis using Indian medicinal plants. 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.

Recent trends in the electrochemical sensors on ?- and calcium channel blockers for hypertension and angina pectoris: A comprehensive review
Calcium channel blockers; Coronary artery disease; Electrochemical sensors; Hypertension; Nanomaterials; ?-Blockers
Stress, ingrained human behaviors, an inactive lifestyle, and poor dietary decisions are the primary causes of hypertension and the related coronary artery disease (CAD), which is also commonly referred to as angina pectoris. Effective high blood pressure (BP) treatment represents a substantial approach to reducing the burden of hypertension-related cardiovascular and renal diseases. A group of drugs known as ?-blockers and calcium channel blockers (CCBs) are frequently used to treat diseases like hypertension (high blood pressure), cardiac arrhythmias and heart failure. For efficient therapeutic use and to reduce potential side effects, ?-blocker concentration monitoring is essential. Chromatographic techniques are employed in a wide range to detect ?-blockers and CCBs without interference, among other analytical methods that have been described. For the detection of ?-blockers and CCBs, electrochemical sensors provide numerous benefits including sensitivity, selectivity, rapidity, and cost-effectiveness. These sensors can help with patient monitoring in clinical settings, ensuring that the prescription ?-blocker dosage is within the therapeutic range. Since ?-blockers are frequently consumed by people, the contamination can be occurred through discharge of wastewater. The presence and measurement of ?-blockers in water samples enables researchers to evaluate potential risks to aquatic life and public health. In this regard, this review addresses recently developed electrochemical (voltammetric) methodologies and measurement protocols for the determination of both ?-blockers and CCBs in pharmaceuticals, biological fluids, and environmental samples. Additionally, this review also provides an overview of the various advanced nanomaterials such as carbon nanotubes, graphene oxide, metal and metal oxide nanoparticles, polymeric structures, zeolite materials, ionic liquids, perovskite semiconductor-based materials, MXenes, Quantum dots, Nano MIPs and various dimensional materials applied to fabricate chemically modified electrodes/electrochemical sensors to determine the ?-blockers and CCBs. Moreover supplied are tables listing the analyte, modified electrode, measurement method, measuring medium pH, linear detection range (LDR), limit of detection (LOD) and sensitivity as they are cited in the original research. Furthermore, important conclusions are made from the published reports in the last decade and some future perspectives are also suggested. 2023 Elsevier B.V.

A Retrospection on Mercury Contamination, Bioaccumulation, and Toxicity in Diverse Environments: Current Insights and Future Prospects
bioaccumulation; biomarkers; ecotoxicity; mercury fate; methyl mercury conversion
Owing to various industrial applications of mercury (Hg), its release into the environment at high concentration is becoming a great threat to living organisms on a global scale. Human exposure to Hg is greatly correlated with contamination in the food chain through cereal crops and sea foods. Since Hg is a non-essential component and does not possess a biological role and exhibits carcinogenic and genotoxic behaviour, biomonitoring with a focus on biomagnification of higher living animals and plants is the need of the hour. This review traces the plausible relationship between Hg concentration, chemical form, exposure, bioavailability, bioaccumulation, distribution, and ecotoxicology. The toxicity with molecular mechanisms, oxidative stress (OS), protein alteration, genomic change, and enzymatic disruptions are discussed. In addition, this review also elaborates advanced strategies for reducing Hg contamination such as algal and phytoremediation, biochar application, catalytical oxidation, and immobilization. Furthermore, there are challenges to overcome and future perspectives considering Hg concentrations, biomarkers, and identification through the nature of exposures are recommended. 2023 by the authors.

Bioactive compounds; Bioreactors; Elicitation; Scale-up process; Secondary metabolites; Somatic embryogenesis
Secondary metabolites from plants are ubiquitous and have applications in medicines, food additives, scents, colorants, and natural pesticides. Biotechnological production of secondary metabolites that have economic benefits is an attractive alternative to conventional methods. Cell, adventitious, and hairy root suspension cultures are typically used to produce secondary metabolites. According to recent studies, somatic embryos in suspension culture are useful tools for the generation of secondary metabolites. Somatic embryogenesis is a mode of regeneration in several plant species. This review provides an update on the use of somatic embryogenesis in the production of valuable secondary metabolites. The factors influencing the generation of secondary metabolites using somatic embryos in suspension cultures, elicitation methods, and prospective applications are also discussed in this review.

Electrochemical Hydrogenation of Organic Compounds: A Sustainable Approach
Aromatic compounds; Catalysis; Electrochemical hydrogenation; Hydrogen evolution reaction; Polyaromatic compounds
Conventional methods for hydrogenation of organic compounds generally use corrosive catalysts and reagents, along with extreme conditions like high temperatures and pressures. Quenching of corrosive materials does not deter its negative impact on the environment, nor is one safe when it comes to working with high temperature and pressure. Electrochemical hydrogenation (ECH) has proven to be safe and green since most of the efficient reactions are conducted at ambient pressure and temperature, minimizing, and sometimes even negating the use of toxic catalysts and corrosive reagents as compared to conventional methods. This review therefore provides different strategies used for ECH in the past, modification of different electrodes, half reactions taken up for efficient energy usage and catalysts used for different hydrogenation reactions. It presents the advances in electrochemical hydrogenation reactions of organic compounds, starting from simple aliphatic compounds to complex polyaromatics and heterocyclic aromatic compounds. 2023 Wiley-VCH GmbH.

absorption Cayley; divisor Cayley graphs; Euler totient Cayley graphs; involutory Cayley graphs; mixed unitary Cayley graphs; nilpotent Cayley graphs; quadratic residue Cayley graphs; unit graphs; unitary addition Cayley graphs; unitary Cayley graphs; zero-divisor Cayley graphs
The study on graphs emerging from different algebraic structures such as groups, rings, fields, vector spaces, etc. is a prominent area of research in mathematics, as algebra and graph theory are two mathematical fields that focus on creating and analysing structures. There are numerous studies linking algebraic structures and graphs, which began with the introduction of Cayley graphs of groups. Several algebraic graphs have been defined on rings, a fast-growing area in the literature. In this article, we systematically review the literature on some variants of Cayley graphs that are defined on rings and highlight the properties and characteristics of such graphs, to showcase the research in this area. 2023 by the authors.

Interparental Conflict and Young Adult Romantic Relationships: A Systematic Review
college students; conflict; dating; interparental conflict; romantic relationships; systematic review; young adults
In the last two decades, researchers have been progressively investigating the impact of interparental conflict (IPC) on young adults romantic relationships. This systematic review aimed to synthesize literature on IPC and romantic relationship outcomes among young adults and highlight mechanisms found in this link. Following the PRISMA protocol, 3232 studies were identified using Boolean searches on ProQuest, PubMed, EBSCOhost, Jstor, Cochrane, and Google Scholar, and 17 met the eligibility criteria. To be included, in addition to having IPC and romantic relationship outcomes as variables, studies had to be quantitative in design, have a mean sample age of 1825, include only participants in romantic relationships at the time of the study, and be published in English with full text available. The review found that IPC is associated with negative conflict management, both perpetration and victimization of aggression, worse communication, negative conflict behaviors, and poor relationship quality. Other outcomes like relationship satisfaction, commitment, as well as mediator variables in the link between IPC and young adult romantic relationship outcomes, such as attitudes towards marriage and conflict attributions, yielded varied results. Several shortcomings in the methodology of the reviewed articles, such as the research sample and measures, were discovered. To deal with the impact of IPC on offsprings romantic relationships, preventive interventions should be designed and evaluated, and more research with different variables and study designs, with more men, other ethnicities, and more representative sample frames are needed to detect crucial mediators and obtain reliable and generalizable results.

Past decade of supercapacitor research Lessons learned for future innovations
Asymmetric supercapacitors; Electrolytes; Flexible supercapacitors; Self-powered supercapacitors; Supercapacitors; Symmetric supercapacitors
Due to their high power density, long cycle stability, and quick charge/discharge rates, supercapacitors are gaining popularity in the field of energy storage devices. These distinct features have enabled supercapacitors to create their own space in the energy storage device realm. This review addresses contemporary ways to increase not just the power density, rate capability, cycle stability, and other properties of supercapacitors, but also their energy density utilising hybrid topologies. Because electrodes are the most significant component of a supercapacitor cell and the last decade mainly focused on the material realm, this paper focuses on the design of hybrid supercapacitor electrodes with high specific capacitance, as well as the explication of the mechanisms involved. We have also given an insight about the merits and demerits of various electrode materials that have been employed till date. The new trends and improvement in supercapacitor development are also summarized. 2023 Elsevier Ltd

A Review on Recent Trends in Biological Applications of Non-conjugated Polymer Dots
Antibacterial; Bioimaging; Biosensing; Drug delivery; Fluorescence; Non-conjugated polymer dots
With the advancement of zero-dimensional carbon materials, carbon dots (CDs) have received immense attention owing to their exceptional optical properties, tailoring of size, and ease of functionalization. They have wide applications in fluorescent sensing, chemical sensing, bioimaging, photocatalysis, etc. Zero-dimensional polymer nanoparticles are called polymer dots (PDs) and are classified into conjugated and non-conjugated PDs based on their conjugated system. Non-conjugated polymer dots (NCPDs) do not have specific conjugated fluorophore groups, but they have superior chemical stability and water solubility than the conjugated PDs. The carbon core of NCPDs is surrounded by polymer chains containing ample functional groups such as C=O, N=O, and C=N, which are responsible for the luminescent PDs. NCPDs are less toxic, photostable, and biocompatible and are relevant in biological explorations in bioimaging, drug delivery, biosensing, etc. This mini-review provides a systematic overview of the inherent properties and the biological applications of NCPDs. It also emphasises the synergistic impacts on the optical performance of modified PDs and significant future research concerns.

Breast cancer detection: A comparative review on passive and active thermography
Active thermography; Breast cancer; Non-invasive imaging; Thermal imaging; Thermography
Breast cancer is the main cause of death among women due to cancer. Early detection is crucial in controlling the disease. Thermography is a non-invasive imaging method that uses temperature differences on the breast surface to identify tumors. This paper focuses on the various aspects of thermography as a diagnostic tool for detecting breast cancer. It includes a review of the currently existing active thermography approaches used to energize the tumor cell to enhance the thermal contrast on the surface. The comparison of passive and active thermography showed that active thermography was more effective, increasing depth-dependent performance from 3 mm to 9 mm for 1.5 mm sized tumors and accuracy from 54% to 82% without a rise in false positive rates. The contrast between malignant and benign tissue also improved from 0.6 C to 0.9 C, indicating that active thermography increases the performance of passive thermography in various aspects. A comparative study of active thermography reveals that healthy tissues are likely to be damaged if the input parameters are not regulated properly. A comprehensive comparison of various tumor estimation algorithms in the paper concludes that the dynamic analysis using an active approach outperforms static analysis due to a significant decrease in error percentage. 2023 Elsevier B.V.

A review on the immunomodulatory properties of functional nutraceuticals as dietary interventions for children to combat COVID-19 related infections
Antiviral; COVID 19; Food additives; Functional food; Infant food
COVID-19 is a significant threat to humanity in the present day due to the rapid increase in the number of infections worldwide. While most children may be spared of the direct mortality effects of the disease, those with weak immune systems are prone to adverse effects. Child mortality increases due to the stress caused to the health care system that disrupts essential health care needs such as immunisation and antenatal care. The use of functional foods (FF) aids in disease-prevention as they are known to have protective effects against COVID-19 by boosting childrens cellular and humoral immunity. Plant components such as glycyrrhizin, epigallocatechin gallate, allicin, and fucoidan exhibit antiviral properties against various viruses, including SARS-CoV 2. Microbial foods that are made of probiotics, can enhance immunity against various respiratory viruses. Food enriched with additives such as lactoferrin, piperine, and zinc can boost immunity against COVID-19. With proper definitive drug therapy not available for treating COVID-19 and most of the disease management tools rely on symptoms and non-specific supportive care, developing a functional paediatric formulation will prevent further deterioration in infant health. It is wise to investigate the toxicological aspects of Functional Foods components especially when formulating for children. The safe limits of ingredients should be strictly followed during FFs formulation. Stronger regulations with advanced analytical techniques can help to formulate functional foods into the mainstream in child nutraceuticals. The purpose of this review is to compile collective information on the functional nutraceuticals specifically for infants and children up to the age of 10 years that could confer immunity against COVID-19 and other related viruses.

A comprehensive review on energy management strategy of microgrids
Demand response; Distributed energy resources; Energy management; Microgrids; Optimization
Renewable energy resources are a one-stop solution for major issues that include drastic climate change, environmental pollution, and the depletion of fossil fuels. Renewable energy resources, their allied storage devices, load supplied, non-renewable sources, along with the electrical and control devices involved, form the entity called microgrids. Energy management systems are essential in microgrids with more than one energy resource and storage system for optimal power sharing between each component in the microgrid for efficient, reliable and economic operation. A critical review on energy management for hybrid systems of different configurations, the diverse techniques used, forecasting methods, control strategies, uncertainty consideration, tariffs set for financial benefits, etc. are reviewed in this paper. The novelty of reformer based fuel cells, which generates hydrogen on demand, thereby eliminating the requirement of hydrogen storage and lowest carbon footprint is discussed for the first time in this paper. The topics requiring extended research and the existing gap in literature in the field of energy management studies are presented in the authors perspective, which will be helpful for researchers working in the same specialization. Papers are segregated based on multiple aspects such as the configuration, in particular, grid-tied, islanded, multi microgrids, the control strategies adopted besides the identification of limitations/factors not considered in each work.

Cadmium as an Endocrine Disruptor That Hinders the Reproductive and Developmental Pathways in Freshwater Fish: A Review
cadmium; endocrine disruptor; freshwater fish; HPG axis; metallothionein; reproductive and developmental impairments
Cadmium (Cd) is a non-essential element with sub-lethal effects even at low concentrations. The persistent nature of Cd and its tendency to bioaccumulate eventually create harmful effects on water biota, including fish. Cd affects various aspects of hormonal action in fish since it bioaccumulates in the endocrine system and hinders the synthesis, secretion, and metabolic activity of hormones, causing severe damage along the hypothalamuspituitarygonadal axis. Linking reproductive and developmental impairments in fish with ecologically relevant concentrations of individual metals can be challenging due to the complexity of aquatic ecosystems. This review deliberated the significant and novel trends of toxicological difficulties and approaches, including elucidating environmental sources bioavailability and Cd-induced toxic effects in freshwater fish. Both acute and chronic exposure to Cd can cause a range of adverse effects, such as growth inhibition, impaired reproductive capacity, endocrine disruption, and developmental abnormalities in freshwater fish, as evidenced by the present review. These investigations support the concept of Cd as a naturally available pollutant that causes irreversible damage in fish. These findings will help to understand the etiology of environmental circumstances that pose substantial dangers to fish health and are also crucial for preventing and treating exposure-related reproductive disturbances in freshwater fish due to environmental pollution. 2023 by the authors.

Mediating and moderating variables of employee relations and sustainable organizations: a systematic literature review and future research agenda
Conceptual framework; Employee relations; Mediating variables; Moderating variables; Sustainable organizations
Purpose: This study aims to perform a systematic literature review to organize the abundance of information on employee relations (ER) and sustainable organizations. Moreover, this study identifies the research gaps by investigating the review of ER mediating and moderating variables and the relationship between ER and sustainable organizations. Design/methodology/approach: This study is based on the systematic literature review methodology involving 257 studies in the final stage. The Scopus and Google Scholar databases with search criteria employee relations and employee relations and sustainable organization were used to achieve the research objective. After applying inclusion and exclusion criteria, researchers come to the distribution of the articles based on the subthemes, geographical region, types of methods, top authors with affiliation and complete research articles based on the citation. In the final stage, this study concluded with the conceptual model comprising mediators and moderators of ER as well as the mediating and moderating variables of the relationship between ER and sustainable organizations. Findings: The reviewed literature shows that employee relation is an optimal strategy for retaining employees via proper disclosure of human resources (HRs) and ER Index. This study included the top six publishers, namely, Emerald, Elsevier, Sage, Springer, Taylor and Francis and Wiley Online Library, to do an exhaustive review on a specific topic. The findings indicate that after COVID-19, the ER index, HR disclosures and the sustainability of ER are among the new and required paradigm shifts needed to manage a crisis impact and perform productively. The mediator and moderator variables that can improve employeeemployer relationships are organizational trusts, organizational justice, perceived job satisfaction, organizational structure and firm ownership. On the other hand, variables that mediate and moderate the relationship between ER and sustainable organizations are organizational climate, organization trust, organization culture, perceived organization support, psychological empowerment, firm ownership, leadership behavior and attitude, respectively. The findings concluded that harmonious and cordial ER are pertinent in building sustainable organizations and accomplishing organizational goals. Practical implications: The mediating and moderating variables that have been identified can be helpful for enthusiastic researchers in contributing to empirical research. Practitioners and managers can use the findings in making an effective organizational model that develops good employeeemployer relationships and helps create a culture of trust and harmony. This study focuses on exploring the variables of ER, which strengthens employeeemployer relationships and supports organizations to stay agile and attain sustainability to endure in the future. Originality/value: This study insights on the specific mediating and moderating variables of ER and sustainable organizations. Till date, studies exploring constructs of ER and sustainable organizations are still in deficit. Better employee relation reflects and leads to a more resilient organization. Future researchers should explore the connection between pandemics and ER which is done insufficiently in the present time. 2022, Emerald Publishing Limited.
