In the reactions with substituted iodobenzenes, the degree of functionalization was influenced by the substituents on the aryl groups depending on their position, which allowed us to realize control of the PL intensity. The substituents at the 2-position and methyl groups at the 3,5-positions of the phenyl group respectively increased the E11** PL and E11* PL selectivity at ~1230 and ~1100 nm. Methyl groups at the 2,6-positions emerged two new E11** PL peaks. These PL characteristics were prominently observed in the (6,4) SWCNT adducts, which were separated by gel chromatography. Theoretical calculations of model compounds showed that the effect of the substituent at the 2-position on the relative stability of the isomers with different binding configurations was greater for the diarylated SWCNTs than for the hydroarylated SWCNTs. Experimental and theoretical calculation results revealed that the choice of substituents on the benzene ring was effectively used to modulate the PL wavelength, and these substituents had a considerable effect on the favorable binding configuration of the SWCNT adduct and relative stability and PL wavelength of the conformational isomers.","PeriodicalId":144,"journal":{"name":"Chemistry - A European Journal","volume":" ","pages":"e202404529"},"PeriodicalIF":3.9,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142996981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we present an intelligent multi-enzyme molecular machine(iMEMM) as a model system for achieving the deracemization of D, L-phosphinothricin (D, L-PPT). The entire system leverages electrochemical power and enzyme-catalyzed (cascade) reactions to establish substrate channel and enhance efficiency. By modularizing each reaction step and using electrochemical real-time monitoring of the reaction process, a single-step electrobiotransformation efficiency of up to 98% and a chiral target L-PPT synthesis efficiency exceeding 99% have been achieved. This iMEMM eliminates the need for intermediate separation, enabling a \"substrate in, product out\" process.

Stochiometric KNN (K0.5Na0.5NbO3) was prepared, by combining alkali-nitrate salts (NaNO3 and KNO3) with the hexaniobate ([HxNb6O19]8-x, Nb6) species in water, followed by heating at elevated temperatures for at least one hour. Ex situ heating of the amorphous alkali-Nb6 precursor reveals stoichiometric control and phase uniformity are possible in making KNN, versus a solid-state route. In situ heating in a transmission electron microscope (TEM), with selected area electron diffraction (SAED), facilitates monitoring the real-time transformation of the amorphous alkali-Nb6 precursor, to yield monoclinic KNN, in agreement with ex situ results.

Moreover, compared with NIR-2, NIR-1 bearing hydrophilic PEG chain displayed not only more rapid clearance but also lower background signal to efficiently distinguish APP/PS1 mice and wild-type mice with higher signal-to-background ratio, which was further validated by ex vivo histological staining of brain tissues.

For treating ophthalmic diseases, one of the strategies is to regulate oxidative stress through antioxidants. Here we conjugate a polyphenolic antioxidant drug (i.e., caffeic acid) with a small peptide of protein tag to generate a peptide-drug conjugate as a nanodrug. With a self-assembled ability to form nanoparticles, the nanodrug mainly enters human corneal epithelial cells (HCEC) by caveolin-mediated endocytosis, succeeds lysosomal escape, and achieves mitochondrial localization of caffeic acid. Revealed by free radical scavenging experiments, the nanodrug shows considerable antioxidant capacities. In mouse leukemia cells of monocyte macrophage (RAW 264.7) induced by lipopolysaccharide (LPS), the nanodrug inhibits various pro-inflammatory cytokines (e.g., NO, IL-6, and TNF-α) by up-regulating the expression of anti-apoptotic protein (e.g., Bcl-2). As an investigation of alleviating oxidative stress by the mitochondrial localization of antioxidant, this work may establish an experimental foundation for the regulation of cellular redox balance, as well as provide different insights for the clinical development of antioxidant drug delivery systems in the treatment of ocular disease.","PeriodicalId":144,"journal":{"name":"Chemistry - A European Journal","volume":" ","pages":"e202402441"},"PeriodicalIF":3.9,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142996894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The traditional anthraquinone method for H2O2 synthesis has environmental and safety concerns due to the use of organic solvents and hazardous by-products. The direct synthesis of H2O2 from H2 and O2 poses risks of flammability and explosion. Recently, the 2-electron oxygen reduction reaction (2e- ORR) method has emerged as a promising alternative, offering safety, environmental friendliness, and cost-effectiveness. This method utilizes gas diffusion electrodes to efficiently generate H2O2 without the need for additional dilution. In this review, we focus on the recent advancements in noble-metal-free materials for 2e- ORR electrocatalysis, which play a crucial role in the efficient production of H2O2. These materials, including transition metal compounds, macrocyclic complexes, carbon-based catalysts, framework materials, and MXene catalyst, demonstrate significant advantages in enhancing H2O2 yield. The development of these non-precious metal catalysts can reduce costs and improve sustainability and promote the commercialization of related technologies.

Synthesized nickel selenoether electrocatalysts which follow a ligand-centered pathway demonstrated remarkably high turnover frequency (kobs) upto 14000 s-1 with 93% Faradaic Efficiency (F.E.). Whereas Ni-electrocatalyst having N-donor and selenoether ligands follow a metal-centered HER and show kobs value of 2110 s-1 with F.E. of 98%. A kinetic isotopic effect (KIE) study using CD3CO2D provides kH/kD = 0.49 and 13.01 values for two types of catalysts suggestive of metal-centered and ligand-centered catalytic behavior, respectively. Also, EPR studies revealed nickel-centered and ligand-centered radicals in two types of Ni-electrocatalysts.

Considering the limits of isolated 2D systems in photovoltaics, one most effective solution is stacking them into van der Waals heterostructures (vdWHs). However, the favorable factors for photovoltaics in vdWHs is still uncertain, nor the intrinsic principles is clear. Here, based on monolayer InSe and β-Sb, we propose a boosting strategy on photovoltaics through stacking them into vdWH. After confirming its experimental feasibility, several superior photovoltaic characteristics of such vdWH are verified than its components. Including more moderately indirect-to-direct band gap, higher electron mobilities, the hindrance of carrier recombination due to the staggered type-II band alignment, and the stronger and red-shifted optical harvesting abilities owing to the band redistribution. In addition, superior characteristics in the InSe/Sb vdWH based photovoltaic devices are further confirmed, including the red-shifted photocurrent into the infrared-light range, the superior photoelectric conversion efficiencies in the visible-light-region, and the higher photovoltaic quality factors (Rph ,τeqe et.al.) than each component and many other typical vdWHs. Obviously, the design principles and promotion mechanisms of 2D vdWH on photovoltaics can provide powerful theoretical guidances for next design and applications of 2D high-efficiency solar photovoltaic cells.","PeriodicalId":144,"journal":{"name":"Chemistry - A European Journal","volume":" ","pages":"e202403637"},"PeriodicalIF":3.9,"publicationDate":"2025-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142996856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
