Summary: N-heterocyclic carbene (NHC)-modified ligands were tested for coordinating and stabilizing luminescent CdSe-ZnS core-shell quantum dots (QDs) in hydrophilic media. The coordination of NHC ligands onto QDs was found to be rapid and effective, leading to enhanced long-term colloidal stability and changes in optical and spectroscopic properties of the nanocrystals, including red-shift in absorption and fluorescence spectra and intensity changes under different storage conditions.

Summary: In this paper, a straightforward synthesis method for NHC-coated gold nanoparticles (NHC-AuNPs) is reported. The commercially available gold(I) precursor is treated with an easy-to-synthesize NHC-BH3 reagent, serving as both the reducing agent and the source of surface ligands. The strategy allows efficient control over the nucleation and growth of gold particles, resulting in a wide range of particle size variation from 4.9±0.9 to 10.0±2.7 nm. The NHC-AuNPs obtained exhibit narrow size distributions, stability over months, and do not require extensive purification or size-selectivity techniques.

Summary: In this study, the catalytic activity of a series of platinum(II) pre-catalysts with N-heterocyclic carbene (NHC) ligands in the alkene hydrosilylation reaction is reported. The structural and electronic properties of these catalysts are fully characterized using X-ray diffraction analysis and nuclear magnetic resonance spectroscopy (NMR). A structure-activity relationship within this group of pre-catalysts is established, and mechanistic insights into the catalyst activation step are provided. One of the complexes shows exceptional catalytic performance, achieving a turnover number (TON) of 970,000 and a turnover frequency (TOF) of 40,417 h(-1) at 1 ppm catalyst loading. Furthermore, a solvent-free and open-to-air alkene hydrosilylation protocol with efficient platinum removal (reducing residual Pt from 582 ppm to 5.8 ppm) is disclosed.

Summary: In this study, gold nanoparticles were functionalized with natural abundance and C-13-labeled N-heterocyclic carbenes to investigate the Au-C stretch. A combination of surface enhanced Raman spectroscopy (SERS) and density-functional theory (DFT) calculations highlighted the vibrational modes significantly impacted by isotopic labeling at the carbene carbon. Critically, none of the isotopically-impacted stretching modes showed majority Au-C character.

Summary: This study presents the successful construction of highly stable and active platinum nanoparticles (Pt NPs) within a three-dimensional porphyrinic nanocage. The nanocage, containing eight N-heterocyclic carbene (NHC) precursors, was prepared using a metal-carbene-templated ring-closing metathesis (RCM) approach, and served as a new capping material for the fabrication and stabilization of Pt NPs. The NHC-stabilized Pt NPs within the nanocage exhibited high catalytic activity for the selective oxidation of 2-chloroethyl ethyl sulfide to nontoxic 2-chloroethyl ethyl sulfoxide, with excellent stability and recyclability.

Summary: This study investigated the chemical and structural changes in dentin during the application of a mild universal adhesive. It was found that the etch-and-rinse mode led to a decrease in inorganic apatite and a reorganization of the mineral phase, while the self-etch mode formed a low amount of adhesive phosphate monoesters calcium salt. The adhesive had a similar interaction with dentin collagen in both modes, but the presence of isopropanol as the solvent significantly reduced the amount of free water molecules without significant changes in collagen structure.

Summary: Doubly thermo-and pH-responsive PNIPAM-b-PDEAEAM polymers were synthesized by RAFT polymerization. The properties of these polymers and corresponding homopolymers in solution depend on pH and the protonation degree of the diethylamino moiety. The behavior of the polymers is also influenced by the nature of the polymer chain ends. At pH 10, both PNIPAM and PDEAEAM blocks contribute to phase transition and form stable spherical nanoobjects. At pH 4, PNIPAM-b-PDEAEAM with longer PDEAEAM length exhibits a two-step thermoresponsive behavior and forms large aggregates with a positively charged shell.

Summary: A pure mixed-anion Fe(NH(2)trz)(3)(BF4)(SiF6)(0.5) spin crossover complex is obtained through a solid-liquid post synthetic modification approach from the Fe(NH(2)trz)(3)(BF4)(2) parent complex. Highly crystalline powder samples incorporating homogeneous micrometric (1 & mu;m long) rod-shaped particles can be achieved using this method. This compound exhibits an abrupt spin crossover behavior with a narrow (10 K) hysteresis loop centered just above room temperature (320 K), making it highly interesting for integration into various application devices.

Summary: This study elucidates the crucial role of amine surfactants in the controlled anisotropic growth of ZnO nanoparticles and their impact on the nature of molecular species in solution, as well as the dynamic behavior on the surface of the grown ZnO nanocrystals. The structuring influence of alkyl substituents on the nitrogen atom of amines strongly influences the formation of molecular species in the solution and the subsequent growth of ZnO nanocrystals. Surface dynamic behavior, particularly H-bonding, plays a predominant role in driving nanocrystal growth and morphology determination, highlighting the importance of weak surface interactions in nanoscience progress.

Summary: The study demonstrates the formation of stable carbides during CO bond dissociation on small ruthenium nanoparticles through DFT calculations and solid state C-13 NMR techniques. The mechanistic investigations reveal that carbide formation via hydrogen-assisted hydroxymethylidyne pathways is exothermic and occurs at reasonable kinetic cost on standard sites of the RuNPs. The possible formation of mu(6) ruthenium carbides in the tip-B-5 site, as well as the rearrangement of surface metal atoms resulting in a pseudo-octahedral metal center on the NP surface, are novel outcomes of the DFT study.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
