Ethylammonium nitrate (EAN) and other ionic liquid (IL) systems with nitrate anion in glass or quartz spaced confinement demonstrate anomalous cation dynamics that differ from those observed in bulk and in nano-confinement. It was demonstrated that the principal axis of the nitrate anion exhibits preferential orientation to the surface, akin to that in liquid crystals. It was shown that the cation translational mobility reversibly changes during exposure to a static magnetic field. This phenomenon was interpreted as a result of intermolecular structure transformations occurring in the confined ILs. The mechanisms of these transformations were discussed.","PeriodicalId":505470,"journal":{"name":"Applied Chemical Engineering","volume":"43 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140975481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The penitential adsorbing of two dyes: methylene blue (BM) and malachite green (GM) was studied on this clay. Firstly, this clay was characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) analysis and X-ray fluorescence analysis. And on the other hand, Effect of different parameters on adsorption kinetics has been studied, such as contact time, initial dye concentration, pH, salinity and temperature. Adsorption tests results showed that equilibrium was established after 30 min and the adsorption of the two dyes depends on the initial dye concentration and the pH. The results showed was the adsorption of the two dyes can be described by pseudo-second-order kinetics. The results indicate also that the process is a spontaneous endothermic physisorption characterized by disorder of the environment. This study shows that this raw, abundant and low-cost natural illitic clay can be valorized and exploited to treat effluents loaded with synthetic dyes.","PeriodicalId":505470,"journal":{"name":"Applied Chemical Engineering","volume":"144 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140222947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to investigate the thermos-kinetic parameters of municipal solid waste through pyrolysis. The sample was collected and prepared according to the American standards for test materials. Thermogravimetric analysis showed the three distinct regions, while the maximum degradation occurs in the second region within the temperature range of 230–400 ℃. A model-fitting approach using the Coats Redfern model was applied in this region to perform thermo-kinetic analysis. Based on the kinetic analysis, the D3 diffusion model showed the highest regression coefficient with an activation energy of 16–18 kJ/mole among all three diffusion models. Thermodynamic analysis showed that the pyrolysis process is endothermic, the product has more energy and a well-ordered arrangement of molecules confirmed by the positive change in enthalpy values and negative entropy values. The results demonstrate the usefulness of municipal solid waste in the creation of productive methods for converting to energy.","PeriodicalId":505470,"journal":{"name":"Applied Chemical Engineering","volume":"40 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140244990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fast depletion of fossil-based fuels and climate change issues are driving nations towards exploring an alternate energy resource. Hydrogen energy is one such an option owing to availability of simple and cost intensive technology involvement. Alkaline water electrolysis is one of the simplest ways of producing hydrogen utilizing renewable energy and oxygen as the only byproduct thus not contributing to carbon footprint. However, immediate attention is needed to minimize the cost of electrolyzer components, maintenance and energy. Commercial proton exchange membrane water electrolyzers (PEM) in market employ large capital cost due to high-priced Nafion and other PFSA membranes, titanium endplates and noble metal-based electrocatalysts. As a consequence, researchers are looking into the usage of Anionic exchange membrane (AEM) for water/alkali based electrolyzer for producing hydrogen with non-noble metal electrocatalysts and low-cost metal end plates. In this article a waste coconut shell derived biochar is explored as the carbon matrix for base of electrocatalysts to replace other high-cost carbon support for electrocatalyst in water electrolyzer. The structural and electrical properties of the coconut shell biochar are studied and compared with other available carbon supports. To deep drive in the electrolyzer performance this approach is further extended to MEA (Membrane Electrode Assembly) level to study the metal free electrocatalyst behavior in real-time environmental conditions.","PeriodicalId":505470,"journal":{"name":"Applied Chemical Engineering","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140242447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, there have been significant research endeavors focused on the quantitative analysis of these heavy metal ions. There is an increasing demand for cost-effective, sensitive, selective, and rapid methods for detecting them. In the context of functional materials for detection as well as effective diminution of heavy metal ion, glutathione is recognized as well as widely proven for its’ robust capacity to form complexes with harmful heavy metal ions, with its solubility in water, enduring action, and convenient accessibility. Consequently, glutathione is increasingly being utilized as a preferred molecular probe in the development of highly sensitive, cost-effective, and easily accessible sensors. Keeping in cue of the increasing use of glutathione, this mini-review provides a summary of the findings from different glutathione-based heavy metal ion detection approaches as documented in recent literature. These approaches are classified according to their respective techniques of signal transduction. The discussion and comparison of their operation and execution, as well as the evaluation of figures of merit such as limit of detection, selectivity, and response time, are presented.

The definitive roles of these medicinal plants in Omicron treatment have been investigated through quantum mechanics and molecular mechanic methods. However, given the unprecedented challenges faced should be given a fair amount of consideration for contribution during this pandemic. In this work, it has been investigated the compounds of achillin, alkannin, cuminaldehyde, dillapiole, estragole and fenchone as a probable anti pandemic Omicron receptor derived from medicinal plants. Anti-Omicron drugs through the hydrogen bonding through physico-chemical properties of medicinal ingredients bound to the database amino acids fragment of Tyr-Met-His as the selective zone of the Omicron have been estimated with infrared (IR) and nuclear magnetic resonance (NMR) methods.
