The existence of arsenic in soil systems is a fate to the environment since it is mobile and being transported to other systems because of its bioavailability and speciation process. Arsenic transformation in the soil and its thorough understanding of how it enters plant systems are crucial. Notably, transporters are responsible for most of the arsenic that enters the plant system. Consumption of crops or animals and drinking water polluted with arsenic are the prime factors in transmitting arsenic to people. Severe adverse effects on humans arise as an outcome of long-term contact with arsenic-rich foodstuff and water. An effort has been made to outline the several sources and their dynamics in the surroundings and health impact on humans in this review. In addition, various strategies have been practiced to remove arsenic in the soil and water systems is also addressed.<h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>","PeriodicalId":801,"journal":{"name":"Topics in Catalysis","volume":"81 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139080299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nanomedicine products offer the possibility of developing complex targeting approaches as well as multifunctionality. Nanotechnology has been examined for the detection of extracellular cancer biomarkers and cancer cells, as well as in vivo imaging, sensitive and selective, accuracy, and multiplexed detection capacity. In fact, nanoparticles have the potential to not only address the limitations of traditional cancer diagnosis and treatment, but also to open up entirely new possibilities and develop cutting-edge technology for tumour detection and treatment. Nano carriers are used to increase target tumour cell specificity and delivery capability to the tumour site, enhancing therapy efficacy while reducing unwanted side effects. Nanocarriers that respond to exogenous or endogenous stimuli have emerged as a promising alternative to target drug delivery. In this review intervention of nanoparticle system for cancer types like Lung cancer, Breast cancer, Melanoma, Colorectal cancer, Bladder cancer are discussed.

A heterogeneous industrial waste catalyst, notably black pepper seed-KOH, was proposed because it can offer sustainability in biodiesel production. While among first generation oil feedstocks, palm oil stands out due to its high productivity because more palm oil can be generated per land area than others. Despite the most common use of the pseudo-first-order kinetic model in biodiesel studies, limited attention has been given to the second-order and reversible kinetics studies. Therefore, catalyst characterization encompassed SEM, EDX, TGA, PSA, FTIR, and basicity tests were first performed. Then, transesterification was executed at different temperatures (50–70 °C), 240-minute reaction time, 6:1 methanol-to-oil ratio, 5 wt% catalyst loading, and 200 rpm to obtain the best fit kinetic model and thermodynamic data. The results displayed a pseudo-irreversible first-order kinetics. Activation energy and pre-exponential factor were determined as 61.5195 kJ mol−1 and 1.1367 × 107 min−1. While, thermodynamic value was calculated, ΔH = 58.7528 kJ mol−1, ΔS = − 0.0850 kJ mol−1 K−1 and ΔG = 86.2157 to 87.9162 kJ mol−1. Therefore, the transesterification was defined as an endothermic, endogenic, and non-spontaneous reaction. This study demonstrates the black pepper seed-KOH’s efficacy in biodiesel production and enhances understanding of kinetic and thermodynamic parameters governing the transesterification process.","PeriodicalId":801,"journal":{"name":"Topics in Catalysis","volume":"312 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2023-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139051519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An abundance nanoparticle (NPs) has been successfully used in a variety of organic transformations, which prompted us to undertake concentrated efforts to cover all instances in which gold nanoparticles (Au NPs) have been used in organic transformations. The catalytic application of gold nanoparticles in organic transformation has gained considerable interest researchers owing to its physical and chemical properties. Gold nanoparticles as catalysts in organic reactions deliver robust, green, and cost-effective alternatives for the synthetic transformations of heterocyclic scaffolds. Nitrogen- and oxygen-containing heterocyclic atoms are the essential prime units existing in diverse carbon-based vibrant lives and are substantial for industrial, pharmaceutical, and agrochemicals. Our focus will be on Au NP-catalyzed reactions in synthetic transformations for the production of heterocyclic scaffolds containing nitrogen and oxygen heteroatoms documented from 2011 to 2022. From a synthetic standpoint, this review will offer the reader an intrinsic framework for selecting the optimal Au NP catalytic system of importance for the synthesis of the preferred heterocyclic scaffold.<h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>\u0000","PeriodicalId":801,"journal":{"name":"Topics in Catalysis","volume":"15 4","pages":""},"PeriodicalIF":3.6,"publicationDate":"2023-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138518994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, iron catalysts typically produce olefin-rich hydrocarbons, which make it difficult to directly use them as liquid transportation fuels. Here, we present a bimetallic Na–Fe0.9Mg0.1Ox catalyst that produced paraffin-rich long-chain hydrocarbons with a high C5+ yield of 17.9% at a high CO2 conversion of 42.1%. The formation of oxygen vacant sites at the catalyst surface and electron transfer from MgO to Fe phase increased the reducibility of Fe3O4 to α–Fe. In addition, the presence of MgO increased the H2 and CO2 adsorption and facilitated the C–C coupling reaction to produce long-chain paraffins. The high CO2 conversion, high C5+ yield, and paraffin-rich products make Fe0.9Mg0.1Ox a highly promising catalyst to produce liquid transportation fuels under industry-relevant conditions.","PeriodicalId":801,"journal":{"name":"Topics in Catalysis","volume":"14 ","pages":""},"PeriodicalIF":3.6,"publicationDate":"2023-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138518995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
