This review paper presents the results of a study conducted using nuclear magnetic resonance (NMR) methods to investigate the dynamic behaviour of ionic liquid-based compositions in micrometre-spaced confinement. 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.

The objective of this work is to valorize abundant illitic clay from Morocco in the treatment of industrial effluents likely to be loaded with synthetic dyes such as the textile, stationery, cosmetic, food, and also pharmaceutical industries. 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.
这项工作的目的是将摩洛哥丰富的伊利石粘土用于处理可能含有合成染料的工业废水，如纺织、文具、化妆品、食品和制药行业。我们研究了这种粘土对亚甲蓝（BM）和孔雀石绿（GM）这两种染料的吸附能力。首先，通过扫描电子显微镜（SEM）、傅立叶变换红外光谱（FT-IR）、X 射线衍射（XRD）分析和 X 射线荧光分析对这种粘土进行了表征。另一方面，研究了不同参数对吸附动力学的影响，如接触时间、初始染料浓度、pH 值、盐度和温度。吸附试验结果表明，30 分钟后达到平衡，两种染料的吸附量取决于初始染料浓度和 pH 值。结果表明，这两种染料的吸附可以用假二阶动力学来描述。结果还表明，该过程是一个自发的内热物理吸附过程，其特点是环境的无序性。这项研究表明，这种原料丰富、成本低廉的天然伊利石粘土可用于处理含有合成染料的污水。

Microwave-induced organic methods are extremely useful in synthetic organic chemistry for the preparation of molecules. A combination of irradiation and high temperature is probably responsible to obtain the final product in an accelerated process. This review focuses on a crucial nucleophilic reaction using hydroxy beta-lactams as the starting compounds. Specifically, the reaction of cis- and trans-hydroxy beta-lactams with different types of glycals under microwave irradiation using iodine as the catalyst is explored. This reaction produces unstaturated glycosides through Ferrier Rearrangement.

Renewable and sustainable energy resources are the dire need of time for environmental sustainability and to minimize the effects of global warming and climate change. 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.

The research presented in this article has focused on the identification of the potential use of two methods: weight change analysis and swelling-weight balancing, to study polymer and silicone rubber samples at consistent temperatures for an extended period. This ensures the stability of these materials for future industrial applications. Throughout the research, it was determined that these methods allow for simultaneous observation of various processes to which the samples were exposed, including degradation and thermal oxidation. The analysis of the obtained results has indicated that a sample made of methylvinylsilicon rubber containing 2% vinyl by weight exhibited superior properties compared to other samples. These properties include a decrease in the rate of rubber chain bond breakage, resistance to various solvents, and improved mechanical characteristics.

In recent days, a steady growth is being noted in hydrogen energy field owing to the global rise in population and increased energy demand. 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.

The prevalence of heavy metal ion contamination is increasing worldwide—posing a growing threat to both ecological and human well-being. 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. Likewise, removal mechanisms along with challenges are also briefed in this mini-review.

This research article aims to investigate six selected medicinal plants of Achillea millefolium (Yarrow), Alkanet, Rumex patientia (Patience dock), Dill, Tarragon, and Sweet fennel including some principal chemical compounds of achillin, alkannin, cuminaldehyde, dillapiole, estragole and fenchone. 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. A comparison of these structures has provided new insights for the design of substrate-based anti-targeting Omicron. Finally, five medicinal ingredients of achillin, alkannin, cuminaldehyde, dillapiole, and estragole bound to TMH have conducted to a Monte Carlo (MC) simulation for evaluating the absorbance of these inhibitor-active site complexes. Here, we used the network pharmacology, metabolite analysis, and molecular simulation to figure out the biochemical basis of the health-raising influence of medicinal plants. This research article peruses the drug ability, metabolites and potential interaction of some medicinal plants with Coronavirus-induced pathogenesis.

The classical and the nano-structured spatial light modulators (SLMs) especially based on the polyimide photosensitive layers, as the key element of the optoelectronic devices, display, and telecommunications schemes are considered. The main emphasis is placed on the device with a polyimide photo-layer due to its high sensitivity and acceptable performance. A modulator’s basic characteristics are studied taken into account the comparison with the different types of the photo-layers, such as: ZnSe, ZnS, a-Si:H. Liquid crystal (LC) media is considered as the modulation system. It is indicated that the different methods and approaches are applied for investigation of the basic SLM parameters, such as: Z-scanning technique, third harmonic generation, four-wave mixing set-up, etc. In the current paper the laser holographic technique is used to investigate the resolution, sensitivity, and speed of the LC-SLM devices. The influence of the fullerene doping on the organic photo-layers based on the polyimide materials is presented. This influence of this nano-structuration process on the modulator’s basic parameters is discussed.
