Summary: This study investigates the kinetics of hydrogen cathodic reduction on low-carbon steel in hydrochloric acid solutions containing corrosion inhibitors, namely quaternary ammonium salts and a 3-substituted 1,2,4-triazole. The results show that the addition of these inhibitors inhibits the cathodic reduction and penetration of hydrogen into the steel. The 3-substituted 1,2,4-triazole is found to be the most effective inhibitor of hydrogen absorption.

Summary: Carbon steel is widely used in severe industrial conditions and is highly susceptible to corrosion. Traditional corrosion inhibitors, although effective, are toxic to humans and harmful to the environment. Ionic liquids, as a new alternative, have shown promising results as corrosion inhibitors for carbon steel in hydrochloric acid. This review presents recent advances in the application of ionic liquids for corrosion inhibition, with all results obtained from potentiodynamic polarization tests.

Summary: In this study, triazole derivatives were synthesized as a new eco-friendly corrosion inhibitor, named C207, for protecting Q235 steel from corrosion in NaCl solutions. Excellent performance was confirmed by electrochemical measurements, showing that C207 acted as an anode corrosion inhibitor with over 96% inhibition (at 50 mg/L) within 48 hours. Surface morphology and structure analysis indicated the formation of coordination bonds between C207 and Q235 steel. Quantum chemical calculations and molecular dynamics simulations supported the experimental findings, suggesting that C207 could be a potential corrosion inhibitor for harsh seawater environments.

Summary: The study found that different isomers of aminobenzoic acid can spontaneously adsorb on the Fe(110) surface, with weak interactions dominating the adsorption. An inhibition efficiency isomeric effect, as observed experimentally, was also identified.

Summary: This study investigates the interaction between phenyltetrazole derivatives and iron using different density functional methods and basis sets. The results show that meta-GGA functionals are suitable for predicting metal-ligand interactions in the complexes. The interaction between iron and phenyltetrazole compounds occurs mainly through Fe-Me/Me-O/CI, Fe-O, and Fe-N interactions. The inhibitors CI-Ph-T and Me-O-Ph-T have low bond energies and enthalpies, and exhibit similar modes of action. The high adsorption energy of CI-Ph-T and Me-O-Ph-T inhibitors suggests that they are the most stable and have the strongest adsorption.

Summary: The support of Schiff base catalysts on solid substrates, especially biocompatible ones, has become more important due to their incredible growth in chemical syntheses. In this study, cobalt-based Schiff catalysts were immobilized on nanocellulose and characterized by FT-IR, H NMR, EDX, and SEM. Among these catalysts, the one with a crown ether substitute showed superior catalytic activity for oxidation of sulfides. It is noteworthy that these catalysts can be recycled multiple times without losing efficiency.

Summary: p_Aminophenol, also known as 4-aminophenol (4-AP), is a chemical compound with hydroxyl and amino groups on the benzene ring. It is a suitable precursor for synthesizing oxazoles and oxazines. However, the toxicity of aniline and phenol poses a risk to human and environmental health, so it is important to develop reliable techniques for detecting and eliminating trace amounts of amino phenols.

Summary: In this study, a Schiff-base-manganese complex containing a crown ether was synthesized and immobilized on nanocellulose (MnL2@nanocellulose) for catalytic oxidation of benzyl alcohols. Characterization techniques including FT-IR, H-NMR, EDX, UV-Vis, microanalysis (CHN and ICP) and SEM were used. Compared to the analogue without crown ether (MnL1@nanocellulose), MnL2@nanocellulose exhibited better catalytic activity despite having a lower Mn content. (c) 2023 Elsevier B.V.

Summary: An easy, efficient, and environmentally friendly catalytic protocol for the synthesis of medicinally important heterocycles is needed to reduce biological pollution and use environmentally friendly and inexpensive solvents. A novel multi-functional composite, C3N4/Fe3O4@P2W15V3, was constructed and effectively synthesized for this purpose. This heterogeneous catalyst produced various tetrahydrobenzo[b]pyran derivatives in the presence of ethanol as a green solvent, allowing for high yield, short reaction time, and high purity due to the presence of a heterogeneous and reusable catalyst.

Summary: In this work, a new dendrimer modified magnetic graphene oxide (GO) was used as a substrate for electrodeposition of Au nanoparticles. The modified magnetic electrode was employed for sensitive measuring of As(III) ion as a well-established human carcinogen. The prepared electrochemical device exhibits excellent activity towards As(III) detection using the square wave anodic stripping voltammetry (SWASV) protocol. At optimum conditions (deposition potential at -0.5 V for 100 s in 0.1 M acetate buffer with pH 5.0), a linear range from 1.0 to 125.0 μgL-1 with a low detection limit (calculated by S/N = 3) of 0.47 μg L-1 was obtained. In addition to the simplicity and sensitivity of the proposed sensor, its high selectivity against some major interfering agents, such as Cu(II) and Hg(II) makes it an appreciable sensing tool for the screening of As(III). In addition, the sensor revealed satisfactory results for detection of As(III) in different water samples, and the accuracy of obtained data were confirmed by inductively coupled plasma atomic emission spectroscopy (ICP-AES) setup. Accounting for the high sensitivity, remarkable selectivity and good reproducibility, the established electrochemical strategy has great potential for analysis of As(III) in environmental matrices.

The structures of these conjugates were determined by spectroscopic techniques and X-ray diffraction. The hydrogen bonds and stacking interactions played important roles in the stabilization of crystal packings. N-H...S, C-H...N, and C-H...Cl hydrogen bonds were observed in the networks, with N-H...S ones having the bigger contribution than stacking interactions.

Summary: A new catalyst consisting of a Schiff base attached to an ionic liquid and a crown ether coordinated to cobalt (II) was synthesized and characterized. This catalyst exhibited higher activity in the synthesis of xanthenes and chromenes compared to analogs without the crown ether and ionic liquid. The presence of the crown ether ring and the ionic liquid increased the solubility of the catalyst in the aqueous phase and enhanced its interaction with reactive species, leading to a faster reaction and excellent product yields. The catalyst could be reused multiple times, and the method offered advantages such as short reaction time, use of environmentally friendly solvents, and high yields of products.

Summary: Pt/C and SO42-/ZrO2 were used as catalysts for the synthesis of p-aminophenol through the catalytic transfer hydrogenation of nitrobenzene in water with formic acid as the hydrogen source. The optimal Pt loading for PAP selectivity was found to be 1 wt%. The presence of different valence states of Pt affected both the nitrobenzene hydrogenation and formic acid decomposition. Among different solid acid catalysts tested, SO42-/ZrO2 exhibited the highest catalytic activity for p-aminophenol formation. Under the optimized reaction conditions, the conversion of nitrobenzene reached 80.0%, with a selectivity of 47.6% for p-aminophenol.

Summary: The mechanism of the reaction between CO2 and styrene oxide for cyclic carbonate was revealed using density functional theory calculations. The noncatalytic reaction occurred via a concerted mechanism, while in the presence of guanidine and tetrabutylammonium iodide (TBAI) co-catalysts, the epoxide ring-opening by nucleophilic attack of an iodide anion was predicted to be the rate-determining step. Guanidine acted as the H-bond donor to activate styrene oxide, facilitating the reaction with a lower activation barrier.

A benign decarboxylative approach, utilizing localized surface plasmon resonance (LSPR) assisted catalysis with Cu-NRs, has been developed for the production of alkane analogues from alkyl carboxylic acids under visible light. The catalyst shows a broad substrate scope and high functional group tolerance, without the need for an external oxidant or proton source. A plausible mechanism for this recyclable nano-catalyst has also been proposed based on control experiments.
