The aim of the study is to produce nanofibers using electrospinning with aqueous poly(vinyl alc.)(PVA) solutions Effect of PVA molar mass and concentration and effect of surfactants on the properties of PVA solutions and on the diameter size of electrospun PVA nanofibers were examined It was shown that the viscosity of the polymer solution was increased by increasing PVA molar mass and concentration To obtain the nanofiber structure, optimum PVA_18.000 (molar mass = 18,000 g/mol) and PVA_50.000 (molar mass = 50,000 g/mol) concentrations were found to be 30% weight/weight and 20% weight/weight, resp. With the addition of anionic and cationic surfactants, the viscosity and the elec. conductivity of the polymer solutions were increased while the surface tension and fiber diameters of the nanofibers were decreased (p < 0.05). However, nonionic surfactants have shown no statistically significant effect (p > 0.05). As a result, electrospun nanofibers were produced using PVA and water and the diameters and properties of nanofibers can be modified by controlling the parameters examined in the study. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9SDS of cas: 122-18-9).

We synthesize and characterize the magnetic and thermodn. properties of the quasi one-dimensional organic-inorganic hybrid ANiCl₃ compounds [A = N(CH₃)₄⁺, CH₃NH₃⁺, (CH₃)₂NH₂⁺, C(NH₂)₃⁺, and CH(NH₂)₂⁺]. Addnl., the crystal structure of (CH₃)₂NH₂NiCl₃ is reported. These materials possess chains of face-sharing NiCl₆ octahedra in a triangular array. The chains run in one direction and are separated from one another by organic cations of different sizes and geometries. In accordance with the 90° superexchange model, we find that the nature of the magnetic coupling within chains can be predicted by the value of the Ni-Cl-Ni angle. As the Ni-Cl-Ni angle decreases from 90°, the magnetic interactions become increasingly antiferromagnetic. These findings provide a foundation for predicting the magnetic properties of quasi one-dimensional organic-inorganic hybrid ANiCl₃ compounds This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Related Products of 75-57-0).

Electrocatalytic activation of organic chlorides via direct and indirect electron transfer using atomic vacancy control of palladium-based catalyst was written by Qin, Shiyi;Lei, Chao;Wang, Xuxu;Chen, Wenqian;Huang, Binbin. And the article was included in Cell Reports Physical Science in 2022.Related Products of 13820-53-6 The following contents are mentioned in the article:

Electrocatalytic dehalogenation (EDH) is a promising green technol. for the breakage of strong carbon-chlorine (C-Cl) bonds that have fundamental importance in organic chem. and environmental remediation. The lack of fundamental understanding and practical issues such as potential secondary pollution, side reactions (e.g., hydrogen-evolution reaction), deficiency in catalytic activity, and/or stability have limited the adoption of EDH technol. Here, we address these problems by designing a palladium-based nanocatalyst with precise control of at. vacancies to exploit the combination of direct and indirect EDH. Exptl. and theor. investigations show that at. vacancies can promote electron transfer on the catalyst surface to enhance the generation/storage capacity of at. hydrogen and to simultaneously facilitate dissociative electron transfer to C-Cl bond. Our work guides the design of at.-vacancy-rich palladium-based electrocatalysts and provides a new strategy for efficient electro-dehalogenation in water and fundamental insights into the relationship of different dehalogenation mechanisms for accurate quant. prediction. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6Related Products of 13820-53-6).

Interactions among the oppositely charged polymer and surfactant are significantly complex in comparison to the interaction between an ionic surfactant and nonionic polymer vis-a-vis the physicochem. properties of the resulting polymer-surfactant solutions In this work, we have deliberated upon the interactions taking place in between a water-soluble anionic polymer, sodium alginate (SA), with a cationic amphiphile, hexadecylbenzyldimethylammonium chloride (C16BzCl), in absence and in presence of sodiumchloride (NaCl) and sodium salicylate (NaSl) employing tensiometric, conductometric, and rheometric measurements. The system was characterized by evaluating physicochem. properties like viscosity curves, critical aggregation concentration (cac), and critical micelle concentration (cmc) as a function of C16BzCl concentration The results show significant differences between the ions furnished by NaCl and NaS1 which could be justified on the basis of effect of solubilization, differential binding of NaSl to polymeric backbone, electrolyte effect, and the solvent modifying tendencies in contrast to the only salt effect of NaCl.

Ethylene evolution reaction (EER) by electrochem. dechlorination of 1,2-dichloroethane is a promising and an economical strategy. The process is however severely impeded by the poor reactivity of catalysts, the accumulation of HCl in the electrolyte as well as low value-added byproducts at anode. Herein, a bifunctional ultrathin Fe-N_x-C single-atom catalysts (SACs) has been successfully prepared and investigated as both cathode and anode material for EER and aromatic chlorination reaction (ACR), resp. The generated HCl was recycled as a chlorinating reagent. The Fe-N_x-C SACs exhibited an excellent electrocatalytic performance simultaneously for both EER and ACR with high ethylene and para-chloroanisole selectivity obtained. The first-principles calculations indicated that Fe-N₄ was the dominating catalytic active site for the generation of ethylene as well as para-chloroanisole. The coupling strategy of ACR at anode not only can accelerate the reaction rate of EER, but also provide a highly-efficient and atom-economical approach for the production of valuable ethylene and aromatic chlorides.

In this study, co-hydrothermal carbonization of rape straw and microalgae was conducted for clean hydrochar. The effect of different feedwater pH values (pH = 1, 3, 5, 7, 9, 12) on co-HTC and the mechanism of enhanced N, S, and O removal were revealed. The acidic and alk. environment of the feedwater exacerbates the carbonization process. The higher heating value (HHV) of the hydrochar formed at pH = 1 reach 22.30 MJ/kg but the value of feedstock is only 13.87 MJ/kg. Deamination and deoxidation were the main method for protein degradation to remove N, S, and O from hydrochar.

And the article was included in Journal of Biotechnology in 2021.Formula: C9H10ClNO2 The following contents are mentioned in the article:

(S)-2-chlorophenylglycine Me ester ((S)-1) is a key chiral building block of clopidogrel, which is a widely administered antiaggregatory and antithrombotic drug. Herein, Protease 6SD was covalently immobilized on multi-walled carbon nanotubes (MWCNT), and the as-prepared immobilizate P-6SD@NH₂-MWCNT was applied in the enantioselective resolution of (R,S)-1 to yield (S)-1. In order to overcome the poor solubility of (R,S)-1 in aqueous solution, a novel triphasic reaction system constituting P-6SD@NH₂-MWCNT, aqueous phase and Me tert-Bu ether (MTBE) as the organic phase was constructed, which simultaneously improved the substrate solubility and the immobilizate recyclability. Under the optimized reaction conditions, P-6SD@NH₂-MWCNT catalyzed 10 mM (R,S)-1 for 2 h, yielding optically pure (S)-1 (>99.0% ee_s) with 70.74% conversion of the (R,S)-1. Moreover, P-6SD@NH₂-MWCNT can be reused for 15 batches, displaying an exquisite recycling performance.

Synthesis and biological evaluation of novel chromonyl enaminones as α-glucosidase inhibitors was written by Mendieta-Moctezuma, Aaron;Rugerio-Escalona, Catalina;Villa-Ruano, Nemesio;Gutierrez, Rsuini U.;Jimenez-Montejo, Fabiola E.;Fragoso-Vazquez, M. Jonathan;Correa-Basurto, Jose;Cruz-Lopez, Maria C.;Delgado, Francisco;Tamariz, Joaquin. And the article was included in Medicinal Chemistry Research in 2019.Application of 95-88-5 The following contents are mentioned in the article:

Series of novel chromonyl enaminones 1a-e and 2a-e and 3-alkylated chromones 3a-e were synthesized and evaluated in vitro as α-glucosidase inhibitors as well as antioxidant and antifungal agents. Antifungal activity was tested on strains of Candida albicans. Compounds 2a and 2d-e showed good inhibition of the α-glucosidase enzyme (IC₅₀ = 5.5, 0.9, and 1.5 mM, resp.), their effect being better than that of 1a-e, 3a-e, and acarbose (the standard, IC₅₀ = 7.73 ± 0.9 mM). The structure-activity relationship suggests that the Ph group at the C-3 position of the chromone ring system and the 4-chlorophenyl group at the enaminone moiety (derivatives 2) increased the inhibition of α-glucosidase. Compounds 2a-e exhibited a slight antioxidant effect, and compounds 3a-e a moderate antifungal activity against C. albicans (IC₅₀ 70.5-83.1 μg/mL). Docking studies revealed that compounds 2 interact with the α-glucosidase residues of the binding pocket. Therefore, these chromone derivatives may be considered as potential α-glucosidase inhibitors, as well as antifungal agents against some Candida strains of yeast. This study involved multiple reactions and reactants, such as 4-Chlororesorcinol (cas: 95-88-5Application of 95-88-5).

4-Chlororesorcinol (cas: 95-88-5) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways.
