Inclusion and exclusion of an azobenzene-containing surfactant with α-cyclodextrin (α-CD) can be used to fabricate photostimulus-responsive vesicle-like aggregates that undergo assembly disassembly reversibly (see picture). The movement α-CD is like a molecular shuttle.
This article reports a new property enabled by nanoparticles, where bismuth nanoparticles added in polymer matrix can block X-ray radiation several times more efficient than microparticles at the same mass ratio. Bismuth are made with cellulose nanofibers and dispersed evenly into polymer. A four time reduction of material is identified 2% ratio when (5 nm diameter) used composite to shield given flux energy radiation, relative those μm diameter). The enhancement shielding primarily...
A novel palladium-catalyzed oxidative C−H functionalization protocol for the synthesis of (2-oxoindolin-3-ylidene)methyl acetates has been developed. In presence Pd(OAc)2 and PhI(OAc)2, a variety N-arylpropiolamides underwent reaction with acids to afford corresponding (E)-(2-oxoindolin-3-ylidene)methyl selectively in moderate excellent yields.
A rhodium-catalyzed/copper-mediated tandem C(sp2)–H alkynylation and intramolecular annulation of 2H-[1,2′-bipyridin]-2-ones with propargyl alcohols for the synthesis 11-acylated imidazo[1,2-a:3,4-a′]dipyridin-5-ium-4-olates is described.
The development of sulfur-tolerant heterogeneous noble metal catalysts with high activity and stability has always been a major challenge. Herein, PdmPn/carbon nanofiber (CNF) tunable crystal phases (Pd6P, Pd3P, Pd5P2, PdP2) were synthesized by simple impregnation–pyrolysis method, their sulfur resistance was systematically studied in hydrogenation sulfur-containing substrates aromatic compounds system. Structural analysis showed that all PdmPn/CNF phase-pure phosphides exhibited similar...
Abstract A new, general method for the synthesis of phenanthridines has been developed by palladium‐catalyzed oxidative remote CH olefination–carboamination–CC bond cleavage tandem reaction. It is noteworthy that alkenes are used as one‐carbon resources this
Batch experiments were conducted to test the effects of various solution properties, such as pH, temperature, initial concentration and anoxic aerobic atmosphere, on Cd removal by nanoscale zerovalent iron (nZVI) supported industrial coal fly ash. (II) could be removed adsorption ash-nZVI in a very short time (5 min) with high rates (greater than 99.9%) over wide range (5-100 mg l-1). was physically adsorbed surface ash-nZVI. The preparation can incorporate use waste media, making overall...
The bis-benzimidazolium salts, 1,2-bis[2-(N-R-benzimidazolemethyl)phenoxy]ethane chloride (L1H2: R = Et, L2H2: nBu), 1,3-bis[2-(N-R-benzimidazolemethyl)phenoxy]propane (L3H2: nPr, L4H2: nBu) and bis[N-R-benzimidazolemethyl]mesitylene 2X (L5H2: nBu, X I; L6H2: PyCH2, Br L7H2: PhCH2, Br), as well their eight NHC silver(I), palladium(II) mercury(II) complexes, [(L1Ag)2Ag2Cl4] (1), [L1(PdCl2CH3CN)2] (2), [(L2Ag)2AgCl2][AgCl2] (3), [(L3Ag2Cl2)n] (4), [(L4Ag2Cl2)n] (5), [L5HgI][HgI4]0.5 (6),...

With the evolution of consumer purchasing power and consumption concepts, external attributes such as fruit size, color, peel smoothness have emerged pivotal determinants influencing preferences; among these, background color exerts a considerable impact on esthetics. The is predominantly influenced by chlorophyll content. Consequently, examining degradation patterns in Prunus persica L. holds significant importance for cultivating varieties with cleaner color. In this study, CP14 20–29 were...
An expedient synthesis of α-aminoboronic acid derivatives via cobalt-catalyzed remote site-selective hydroboration unactivated alkenes is described herein. The strategy characterized by its simplicity, site-selectivity, and wide substrate scope, as both terminal internal could undergo the reaction smoothly, affording corresponding products in good yields. According to mechanism, Co-H generated from Co(acac)2 presence HBpin, which starts chain-walking a series alkene insertion β-H elimination process.
We report on the use of block copolymer micelles polystyrene-b-poly(acrylic acid) (PS-b-PAA) as matrixes for incorporating dibenzyl diselenide. found that water-insoluble diselenide, after being incorporated into micelles, demonstrates glutathione peroxidase (GPx) activity in water. Surprisingly, mimicking system can be adjusted to show higher GPx by increasing ionic strength solution simply upon addition NaCl. Moreover, diselenide is quite stable and maintains its even exposure atmosphere.
A novel RuCl3-catalyzed intramolecular oxidative hydration–deprotonation–cyclization method was developed for the synthesis of substituted quinolinones. The serves as first example direct carbocyclization an alkyne with sp3carbon at α-position amide through deprotonation process.

The as‐prepared exhibit good properties as surface‐imprinted multilayers, because molecules that are locked inside multilayers can act nanocontainers specific binding to certain guest molecules, loading release is redox‐controllable reversible.
A stable solid acid catalyst, cross-linked poly(ether sulfone) containing high content of sulfonic group, was directly synthesized from monomer. It characterized by Fourier transform infrared spectra, thermogravimetric analysis, acid–base titration, and reagent uptake.
