Innumerable health-beneficial properties of sesame lignans like sesamol, sesamolin, sesamin and sesaminol make them lucrative agents in the pharmaceutical industry. To specify the mode of action of these phytochemicals, detailed computational physicochemical properties evaluation, and toxicity assessment (using free web servers and databases), as well as binding interactions with physiological inflammatory effectors (such as COX-2, TNF-α , IL-1 β , IL-6) by means of rigid ligand-receptor docking (using software), have been thoroughly investigated. Interestingly, sesame lignans are conformed to have drug-likeness, indicating their efficacy and suitability like established therapeutics. These bioactive lignans possess drug-like attributes and effectively act as ligands in the present in-silico study. The basic pharmacokinetic profile of these compounds has suggested non-polar solvents or delivery systems for them to enhance their bioavailability in physiological systems. However, all the sesame lignans are toxic to the liver cells with a50 % lethal dose in the range of 500-1500 mg/kg. Toxicity study indicated minimum toxicity of lignans to normal cellular milieu, but noticeable cytotoxic effects against several cancerous cell lines suggesting their anti-carcinogenic properties. Finally, the findings of the molecular docking study have depicted a high affinity of these ligands for target proteins, even better than traditional anti-inflammatory drugs-Indomethacin and Ibuprofen. The molecular interactions have represented sesaminol as the most effective and Sesamol as the least potent ligand for target receptor whereas COX-2 seems to be the most vulnerable target. The docking scores varied widely (-4.7 to -11.0 kcal/mol). The present in-silico approach is expected to provide valuable resources for optimizing bioactive molecules as future-generation therapeutics before pre-clinical and clinical studies.

In this study thermal decomposition routes and kinetics of lead acetate triydrate are compared in inert (nitrogen) and reactive (oxygen) atmospheres by using thermogravimetric method. The decomposition proceeds with five consecutive stages in the both the atmospheres. The first four stages occur similarly in nitrogen and oxygen atmospheres and the same intermediates are formed. However, the last stage, differs according to the furnace atmosphere. The mixture of PbO and small amount metallic Pb is the final product in nitrogen atmosphere whereas the mixture of PbO and Pb 3 O 4 is the final product in oxygen atmosphere. X-ray powder diffraction method is used in identify of these products. Kinetic calculations of all stages are realized by using Kissinger–Akahira–Sunose (KAS) and Flynn–Wall–Ozawa (FWO) model free methods. These methods are combined with modeling equations to find the effective model and to calculate thermodynamic parameters. It is found that all reactions show good harmony with the nucleation models although their indexes are different.

The electrical impedance analysis of the ZnO films has been performed using complex impedance spectroscopy in the frequency range from 100 Hz to 1 MHz with temperature change from 70 to 175 ℃ . Combined impedance and modulus plots have been used to analyse the sample behaviour as a function of frequency at different temperatures. Temperature dependence of ac conductivity indicates that the electrical conduction in the material is a thermally activated process. The frequency dependence of the ac conduction activation energy is found to obey a mathematical formula. It is concluded that the conductivity mechanism in the ZnO sensor is controlled by surface reaction. The operating temperature of the ZnO gas sensor is 175 ℃ . The impedance spectrum also exhibited a decreased semicircle radius as the ammonia concentration is increased from 50 to 500 ppm. In addition, the impedance spectrum also exhibited a decreased semicircle radius with the exposure time increase from 0 to 20 min thereafter slightly increased. Impedance spectroscopy analysis has shown that the resistance variation due to grain boundaries significantly contributed to the gas sensor characteristics.

There are several potential uses for green nanoparticle amalgamated in the medicinal and environmental sciences. Green synthesis specifically tries to reduce the use of harmful chemicals. For instance, it is often acceptable to employ organic resources like plants. In a single green synthesis step, biomolecules found in plant extract may transform metal ions into nanoparticles. This naturally occurring conversion of a metal ion to a base metal may be carried out quickly, conveniently, and at ambient temperature and pressure. In the current study, the production of CuNPs utilizing different-sized Nelumbo nucifera leaf extract has been reported. In order to determine how CuNPs generated, several techniques including UV-Visible, XRD, SEM, EDAX, FTIR, and cyclic voltammetry studies were used. The UV-Visible spectra of the amalgamated CuNPs show a peak between 250 and 450 nm. The morphology of CuNPs are spike in shapes with sizes of 33nm for 10mM and 25nm for 50mM, and the nanoparticles are crystalline in nature, according to the XRD and SEM examinations. The amalgamated CuNPs contain 37.55% copper, according to EDAX, and FTIR shows the absorption peak of copper at 1640 and 576 cm -1 .The oxidation and reduction of amalgamated CuNPs are visible by cyclic voltammetry. CuNPs have been put to the test against Staphylococcus aureus, Staphylococcus epidermidis, Klebsiella pneumoniae, Escherichia coli, and Pseudomonas aeruginosa for their antibacterial properties. CuNPs show the greatest zone of inhibition when used against Pseudomonas aeruginosa . Aspergillus flavus and Candida albicans have been used as test subjects for the antifungal testing of CuNPs. The CuNPs against Candida albicans show the largest zone of inhibition. CuNPs demonstrate strong antibacterial and antifungal efficacy, which means they have a considerable potential for application in the development of medications used to treat bacterial and fungal infections. The electrical potential difference of amalgamated CuNPs has been measured using a voltmeter and it is found that as concentration rises, so does the electrical potential difference.
绿色纳米颗粒在医学和环境科学中有几种潜在的用途。绿色合成特别试图减少有害化学物质的使用。例如，使用植物等有机资源通常是可以接受的。在单一的绿色合成步骤中，植物提取物中的生物分子可以将金属离子转化为纳米粒子。这种自然发生的金属离子到贱金属的转化可以在环境温度和压力下快速、方便地进行。在目前的研究中，已经报道了利用不同大小的荷叶提取物生产乳香多糖的方法。为了确定CuNPs是如何生成的，使用了几种技术，包括uv -可见，XRD, SEM, EDAX, FTIR和循环伏安法研究。其紫外可见光谱在250 ~ 450 nm之间有一个峰值。XRD和SEM分析表明，纳米颗粒为晶体状，粒径为33nm (10mM)和25nm (50mM)。经EDAX测定，铜的含量为37.55%，FTIR在1640和576 cm -1处发现了铜的吸收峰，循环伏安法可观察到铜的氧化和还原。CuNPs对金黄色葡萄球菌、表皮葡萄球菌、肺炎克雷伯菌、大肠杆菌和铜绿假单胞菌的抗菌性能进行了试验。当用于铜绿假单胞菌时，CuNPs显示出最大的抑制区。以黄曲霉和白色念珠菌为试验对象，对其进行了抗真菌试验。对白色念珠菌的抑制区最大。CuNPs显示出强大的抗菌和抗真菌功效，这意味着它们在开发用于治疗细菌和真菌感染的药物方面具有相当大的应用潜力。用电压表测量了其电位差，发现随着浓度的升高，电位差也随之升高。

The present work investigates the Fenton degradation of commercial Auramine O dye from a model solution through advanced oxidation process (AOP). The effects of initial pH, ferrous ion and H2O2 concentration have been evaluated with respect to the extent of decolourization of the feed solution. A maximum decolourization to the tune of 91.8% is accomplished at a pH of 3.0. The effect of various doses of Fe2+ and H2O2 on the percentage reduction in chemical oxygen demand (COD) is investigated at a constant pH. 84.9% reduction of COD is obtained using a combination of 48 mL/L H2O2 and 6 g/L Fe2+. The gas chromatography-mass spectrometry analysis reveals the presence of toxic non-biodegradable Auramine O dye in the model solution before the Fenton AOP, which is degraded into several compounds including CO2 after 30 min of Fenton AOP. The spectral output from FTIR analysis corroborates the molecular rearrangement during Fenton process with consequent degradation.

In present scenario, anthropogenic activities have degraded the quality of water bodies to an unbearable level. Discharge of untreated industrial and other effluents have made the water unconsumable. Present work is an attempt to fabricate new stimuli responsive adsorbent based on natural exudate gum sterculia, an indigenous natural gum for uptake of a cationic dye malachite green. Magnetic field responsive terculia gum–graft-poly(n-isopropylacrylamide-co-acrylamide) nanocomposite have been prepared and assessed it as adsorbents for enrichment of malachite green from aqueous solution. The nanocomposite is characterized by FTIR, TG-DTA, VSM and swelling studies. The VSM results have shown is superparamagnetic behaviour of nanocomposite with saturation magnetization of 1.5065 emu/g. The adsorption follows Temkin isotherm and results indicate maximum adsorption capacity of 19.977 (98.78%) malachite green. The desorption studies demonstrates excellent recovery ability of nanocomposite. The adsorption study confirms the prospective applications of polysaccharide based magnetic hydrogel for the fruitful and greener disposal of cationic dyes.
