Summary: In this study, a ligand intercalation strategy using sodium dodecyl sulfonate (SDS) was employed to enhance the current density and efficiency of electrochemical alcohol oxidation on Co(OH)(2) catalyst. The intercalation of SDS promoted the generation and exposure of CoOOH reactive sites, facilitated the adsorption of alcohol, and significantly improved the reaction rate and selectivity for glycerol electrooxidation.

Summary: In recent years, there has been a strong push towards developing renewable energy sources as alternatives to fossil fuels to meet the increasing global energy demand. Molecular hydrogen (H-2) is considered the ideal energy carrier for the 21st century due to its high energy density and environmentally friendly combustion properties. Developing efficient H-2-evolving molecular electrocatalysts with inexpensive elements is crucial. Among these, [NiFeSe]-H(2)ases show exceptional hydrogen production properties and high tolerance to oxygen, making them promising candidates for practical applications.

Summary: The octahedrally coordinated nickel(II) complexes [Ni(L)2](ClO4)2 (1,2) with (pyridin-2-ylmethyl)amine (L1, 1) and 1-(1-methyl-1H-imidazol-2-yl)-N-(pyridin-2ylmethyl)methanamine (L2, 2) as ligands were synthesized and characterized. The electrochemical hydrogen evolution reaction (HER) in acetonitrile showed that NiI is an active redox center in strong acids like p-toluenesulfonic acid. Compared to analogous Ni complexes, these complexes demonstrated higher catalytic rates and significant TONs at relatively low overpotential, and the HER activity differences mainly arise from the pyridine and imidazole donors in 1 and 2, respectively.

Summary: Thiocarbohydrazone-based catalysts with potentially electrochemically active ligands can be easily tailored for optimization. In this study, a trinuclear nickel-thiocarbohydrazone complex is synthesized and characterized, showing an improved turnover rate compared to its mononuclear counterpart. DFT calculations reveal that the mechanism involved is metal-centered, unlike the metal-assisted ligand-centered mechanism in the mononuclear complex. Two possible mechanisms involving an initial double reduction of the system are proposed for this catalyst.

Summary: A series of porphyrin-based zirconium MOFs were explored for photocatalytic H-2 production, with MOF containing more uniformly dispersed Pt2+ ions showing the highest H-2 evolution reaction rate under visible-light irradiation. The differences in photocatalytic activity were attributed to efficient charge transfer from photosensitizers to catalytic centers in MOF materials.

Summary: Iron porphyrin catalysts are widely used in CO2 reduction reactions, but powering them with photosensitizers still faces challenges. In this study, we designed an iron porphyrin catalyst decorated with urea functions, which acted as a hydrogen bonding scaffold to enhance the photocatalytic activity. The results showed that the catalyst exhibited remarkable photocatalytic activity, and experimental evidence demonstrated the involvement of Fe-I species in the CO2 activation process.

Summary: The development and optimization of catalysts for H-2 production require a comprehensive understanding of the potential catalytic mechanisms involved. Transition metals are often the reactive centers in catalysis, but this can change in the presence of a redox-active ligand. Investigating the differences in catalysis when considering ligand- and metal-centered reactivity is crucial for finding the most efficient mechanisms for hydrogen evolution reaction.

Summary: Computational electron paramagnetic resonance (EPR) spectroscopy plays an important role in connecting spectroscopic observations with the fundamental description of electronic structure. This study focuses on Cu(II) complexes and investigates the performance of double-hybrid density functionals (DHDFs) for predicting g-tensors. The results show that current DHDFs consistently outperform other computational approaches, with B2GP-PLYP and PBE0-DH identified as the best DHDFs for predicting Cu(II) g-tensors.

Summary: In this study, the electrocrystallization of o-DMTTF in the presence of NO2- anion resulted in the formation of (o-DMTTF)(2)NO2, which is the first example of an isolated cation radical salt with NO2-. The salt exhibited semiconducting behavior and a strong 1D structure due to the dimerization of o-DMTTF molecules. Additionally, a spin-Peierls transition was observed at 70 K. The importance of this research is rated 8 out of 10.

X-ray structures of some compounds were determined and the electrochemical behavior was analyzed. Spectroelectrochemical measurements were used to study the electron exchange process, and electron paramagnetic resonance (EPR) and electron nuclear double resonance spectroscopy (ENDOR) were employed to determine the delocalization of radical cations and the coupling constants, respectively. DFT calculations were performed to support the EPR data.

The electrocatalytic activity of Ni4S3-CNF/ITO towards methanol oxidation reaction (MOR) was investigated and showed high activity and stability in an alkaline medium. The addition of carbon nanofibers increased the surface area and improved the tolerance to catalyst-poising species, making it a promising low-cost and efficient fuel cell electrocatalyst.

Summary: This study investigates the stability of three newly synthesized nitroxide candidates with tetraethyl substitution and compares their stability in vivo. The results show that nitroxides with pyrrolidine and pyrroline cores exhibit higher stability compared to isoindoline nitroxide. Metabolite analysis suggests that the transformation pathway of tetraethyl isoindoline nitroxide involves hydrogen abstraction and subsequent modifications by cytochrome P450.

Summary: The effect of applied potential on the crystallography, morphology, optical properties, and electrochemical performances of manganese oxide electrodeposited on ITO substrate was investigated. Lamellar structure was observed in all electrodeposited materials regardless of the applied potential, but the crystallite size, crystallinity, and sheets diameter were affected. Increase in applied potential resulted in higher bandgap energy for all the materials. The electrodeposited material at a potential of 1 V/SCE showed higher specific capacitance and the effect of electrodeposition potential on diffusion and capacitive contributions was analyzed.

Summary: This study presents a new approach for the purification of cadmium-contaminated phosphoric acid using synthesized lamellar material based on manganese (Na-MnO2). The removal efficiencies of cadmium ions were 35% and 31% for 54% and 29% P2O5 phosphoric acid, respectively. Kinetic and isotherm studies were conducted, and the Na-MnO2 material was characterized using various techniques. The results confirmed the potential of Na-MnO2 as an efficient sorbent for heavy metal removal from phosphoric acid solutions.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis.
