Pakrieva, Ekaterina published the artcileSupported gold nanoparticles as catalysts in peroxidative and aerobic oxidation of 1-phenylethanol under mild conditions, Recommanded Product: n-Octanol, the main research area is gold nanoparticle phenylethanol peroxidative aerobic oxidation; 1-phenylethanol; DFT; TBHP; alcohol oxidation; gold; heterogeneous catalysis.

The efficiency of Au/TiO2 based catalysts in 1-phenylethanol oxidation was investigated. The role of support modifiers (La2O3 or CeO2), influence of gold loading (0.5% or 4%) and redox pretreatment atm., catalyst recyclability, effect of oxidant, (tert-Bu hydroperoxide (TBHP) or O2), as well as the optimization of exptl. parameters of the reaction conditions in the oxidation of this alc. were studied and compared with previous studies on 1-octanol oxidation Samples were characterized by temperature-programmed oxygen desorption (O2-TPD) method. XPS measurements were carried out for used catalysts to find out the reason for deactivation in 1-phenylethanol oxidation The best catalytic characteristics were shown by catalysts modified with La2O3, regardless of the alc. and the type of oxidant. When O2 was used, the catalysts with 0.5% Au, after oxidative pretreatment, showed the highest activity in both reactions. The most active catalysts in 1-phenylethanol oxidation with TBHP were those with 4% Au and the H2 treatment, while under the same reaction conditions, 0.5% Au and O2 treatment were beneficial in 1-octanol oxidation Despite the different chem. nature of the substrates, it seems likely that Au+(Auδ+) act as the active sites in both oxidative reactions. D. functional theory (DFT) simulations confirmed that the gold cationic sites play an essential role in 1-phenylethanol adsorption.

Swami, K. Rama published the artcileUnraveling the role of phase modifiers in the extraction of Nd(III) from nitric acid medium in tetra-bis(2-ethylhexyl)diglycolamide in n-dodecane containing long chain aliphatic alcohols, SDS of cas: 111-87-5, the main research area is neodymium extraction nitric acid TEHDGA dodecane alc phase modifier.

Tetra-bis(2-ethylhexyl)diglycolamide (TEHDGA) alone in n-dodecane (n-DD) is unsuitable for the solvent extraction of trivalent actinides from high-level liquid waste due to the occurrence of third phase formation during the course of solvent extraction Significant concentration of long chain aliphatic alcs. ranging from 5% to 15% (V/V) have been added to the solvent phase, TEHDGA/n-DD, to control the undesirable third phase formation. The alcs. investigated were n-octanol, n-decanol, and isodecanol. To understand the role of alcs. in controlling the third phase formation, the extraction behavior of the trivalent metal ion, Nd(III), from nitric acid medium was studied in a solution of 0.2 M TEHDGA + 1 M alc. in n-DD. The equilibrium concentration of Nd(III) and nitric acid present in organic and aqueous phases were determined The organic phase obtained after extraction was subjected to dynamic light scattering studies to unravel the role of alc. phase modifiers in organic phase. The aggregate size and their distribution in organic phase was determined as a function of various parameters such as concentrations of nitric acid, Nd(NO3)3 and the nature of alc. In view of this, the aggregate size was controlled much below the limiting aggregate size required for third phase formation by these alc. phase modifiers. Even though all the alcs. investigated in the present study could bring down the aggregate size much below the limiting value, n-decanol was found to be superior to other alcs.

Liu, Xiangkai published the artcileLuminescent Hydrogel Based on Silver Nanocluster/Malic Acid and Its Composite Film for Highly Sensitive Detection of Fe3+, Recommanded Product: (S)-2-hydroxysuccinic acid, the main research area is silver nanocluster malic acid polymethylmethacrylate hydrogel aggregation fluorescence quenching; AIE; malic acid; self-assembly; sensor; silver nanoclusters.

Metal nanoclusters (NCs) with excellent photoluminescence properties are an emerging functional material that have rich phys. and chem. properties and broad application prospects. However, it is a challenging problem to construct such materials into complex ordered aggregates and cause aggregation-induced emission (AIE). In this article, we use the supramol. self-assembly strategy to regulate a water-soluble, atomically precise Ag NCs (NH4)9[Ag9(C7H4SO2)9] (Ag9-NCs, [Ag9(mba)9], H2mba = 2-mercaptobenzoic acid) and L-malic acid (L-MA) to form a phosphorescent hydrogel with stable and bright luminescence, which is ascribed to AIE phenomenon. In this process, the AIE of Ag9-NCs could be attributed to the non-covalent interactions between L-MA and Ag9-NCs, which restrict the intramol. vibration and rotation of ligands on the periphery of Ag9-NCs, thus inhibiting the ligand-related, non-radiative excited state relaxation and promoting radiation energy transfer. In addition, the fluorescent Ag9-NCs/L-MA xerogel was introduced into polymethylmethacrylate (PMMA) to form an excellently fluorescent film for sensing of Fe3+. Ag9-NCs/L-MA/PMMA film exhibits an excellent ability to recognize Fe3+ ion with high selectivity and a low detection limit of 0.3 μM. This research enriches self-assembly system for enhancing the AIE of metal NCs, and the prepared hybrid films will become good candidates for optical materials.

Schoettl, Sebastian published the artcileCombined molecular dynamics (MD) and small angle scattering (SAS) analysis of organization on a nanometer-scale in ternary solvent solutions containing a hydrotrope, COA of Formula: C8H18O, the main research area is mol dynamics small angle scattering nanometer scale hydrotrope; Detergentless microemulsion; Molecular dynamics; Pre-Ouzo; Small angle scattering; Surfactant-free microemulsion; Ternary mixtures; Ultraflexible microemulsion.

Mixtures of three solvents, with two immiscible liquids and a third one miscible to both – the solvotrope, may exhibit structuration. We explore the phase diagram of n-octanol/ethanol/water, where ethanol is the hydrotrope, varying composition from the water-rich side to the n-octanol-rich side at constant ethanol fraction. We resolve nanometer-sized structures exptl. by mean of four contrasts: three from Small Angle Neutron Scattering (SANS) and one from Small Angle X-ray Scattering (SAXS). On the water-rich side, we confirm the existence of droplets associated to a critical point stabilized by an excess adsorption of the hydrotrope: the ultra-flexible microemulsion (UFME) domain. The n-octanol-rich side is better described as a dynamic random network of chain-like associations of hydroxy groups. The continuous evolution from oil clusters to a dynamic network of hydroxy groups is demonstrated by the features of scattering patterns, successfully compared for all contrasts to Mol. Dynamics (MD) simulations, allowing to illustrate with snapshots the structuration of solvents. The free energy of transfer of the hydrotrope obtained from MD is low (∼1 kBT/mol.). This study suggests that Ouzo spontaneous emulsions may be in dynamic equilibrium with a pre-Ouzo, similarly to nanoemulsions kinetically stabilized by the co-existence of a microemulsion.

Das, Kalicharan published the artcilePhosphine-Free Well-Defined Mn(I) Complex-Catalyzed Synthesis of Amine, Imine, and 2,3-Dihydro-1H-perimidine via Hydrogen Autotransfer or Acceptorless Dehydrogenative Coupling of Amine and Alcohol, SDS of cas: 111-87-5, the main research area is manganese catalyzed dehydrogenative coupling aryl amine benzyl alc; crystal structure thioalkylaminopyridyl manganese cation complex; mol structure thioalkylaminopyridyl manganese cation complex; perimidine benzo preparation; stilbene amino preparation; resveratrol derivative preparation.

The application of nontoxic, earth-abundant transition metals in place of costly noble metals is a paramount goal in catalysis and is especially interesting if the air- and moisture-stable ligand scaffold was used. Herein, the authors report the synthesis of amines/imines directly from alc. and amines via H autotransfer or acceptorless dehydrogenation catalyzed by well-defined phosphine-free Mn complexes. Both imines and amines can be obtained from the same set of alcs. and amines using the same catalyst, only by tuning the reaction conditions. The amount and nature of the base are a highly important aspect for the observed selectivity. Both the primary and secondary amines were employed as substrates for the N-alkylation reaction. As a highlight, the authors showed the chemoselective synthesis of resveratrol derivatives Also, the Mn-catalyzed dehydrogenative synthesis of structurally important 2,3-dihydro-1H-perimidines also was demonstrated. D. functional theory calculations were also carried out to model the reaction path and to calculate the reaction profile.

Stefanucci, Azzurra published the artcileIn Silico Identification of Tripeptides as Lead Compounds for the Design of KOR Ligands, SDS of cas: 111-87-5, the main research area is KOR ligand design tripeptide compound identification; antinociceptive effect; binding; k-opioid receptor; molecular modelling; peptides.

The kappa opioid receptor (KOR) represents an attractive target for the development of drugs as potential antidepressants, anxiolytics and analgesics. A robust computational approach may guarantee a reduction in costs in the initial stages of drug discovery, novelty and accurate results. In this work, a virtual screening workflow of a library consisting of ∼6 million mols. was set up, with the aim to find potential lead compounds that could manifest activity on the KOR. This in silico study provides a significant contribution in the identification of compounds capable of interacting with a specific mol. target. The main computational techniques adopted in this exptl. work include: (i) virtual screening; (ii) drug design and leads optimization; (iii) mol. dynamics. The best hits are tripeptides prepared via solution phase peptide synthesis. These were tested in vivo, revealing a good antinociceptive effect after s.c. administration. However, further work is due to delineate their full pharmacol. profile, in order to verify the features predicted by the in silico outcomes.

Haque, Najirul published the artcileZn(II)-Embedded Nanoporous Covalent Organic Frameworks for Catalytic Conversion of CO2 under Solvent-Free Conditions, Recommanded Product: 3,5-Dimethylhex-1-yn-3-ol, the main research area is zinc embedded nanoporous covalent organic framework catalytic conversion CO2.

Covalent organic frameworks (COFs) have been gaining substantial attention over the past decade due to their developing crystalline porous polymeric nature linked by strong covalent bonds and widespread applications in various fields. Currently, three-dimensional COFs (3D COFs) are engaging the spotlight due to their distinctive porous features, greater surface area, and exceptional performances in comparison with formerly published two-dimensional (2D) frameworks with the AA-stacking layered mode. In this paper, we present, for the first time, a nanoporous 3D-COF-based zinc(II) catalyst (Zn@RIO-1), which shows an efficient pathway for the chem. conversion of carbon dioxide to produce α-alkylidene cyclic carbonates and oxazolidinones from propargylic alcs. The microporous material with a high surface area (312.61 m2/g) facilitates both types of catalytic reactions under atm. CO2 pressure. More importantly, easily recyclable and reusable catalysts produced moderate to high yields of desired carbonates as well as oxazolidinone products under solvent-free conditions. This study emphasizes the capability of nanoporous 3D-COF-based material in the catalysis field, more specifically in the field of CO2 capture and chem. fixation to fine chems. These results pave a spectacular pathway for the chem. fixation of CO2 into α-alkylidene cyclic carbonates and oxazolidinones from propargylic alcs. using 3D-COF as a potential heterogeneous ligand under sustainable conditions (i.e., solvent-free).
