Hydrogen evolution reaction (HER), a promising strategy for converting electricity to value-added H-2 fuel, is a key half reaction of the overall water splitting. However, HER is suffering from the sluggish kinetics in alkaline. We here demonstrate a highly efficient catalyst for alkaline HER via surface and interface engineering of RhOOH nanosheets (NSs). The surface structure of RhOOH NSs can be precisely tuned by altering the cyclic voltammogram cycles (CVs) in the activation process, leading to the formation of strongly synergized RhOOH/Rh interface for boosted HER activity in alkaline. The optimized catalyst exhibits a promising alkaline HER performance with overpotential of 18 mV at current density of 10 mA center dot cm(2) and Tafel slope of 19.3 mV center dot dec(-1) in 1 M KOH, which surpasses the commercial Pt/C, Rh NSs/C and RhOOH NSs/C. Detailed experiments and theoretical calculations reveal that the synergy between RhOOH and Rh significantly promotes the H2O adsorption/ dissociation to form Had and the Had desorption to produce H-2.

Herein, we conceptualized a transient mediator approach that has the capability of para-selective C-H functionalization of monosubstituted aromatics. This approach is enabled by in situ generation of a versatile sulfonium salt via highly electrophilic phenoxathiine or thianthrene dication intermediate which can be readily generated from its sulfoxide with tri-fluoromethanesulfonic anhydride. Preliminary mechanistic study implied that the remarkable para selectivity might be related to the incredible electrophilicity of thianthrene dication intermediate. The versatility of this approach was demonstrated via para-borylation of various monosubstituted simple aromatics combining the sulfonium salt formation with further photocatalyzed transformation.

Methods for direct C-H trifluoromethoxylation of arenes and heteroarenes are rare, despite the importance of trifluoromethoxylated compounds for pharmaceuticals, agrochemicals, and material sciences. Especially selective C-H trifluoromethoxylation of pyridines remains a formidable challenge. Here we show a general late-stage C-H trifluoromethoxylation of arenes and heteroarenes as limiting reagent with trifluoromethoxide anion. The reaction is mediated by silver salts under mild reaction conditions, exhibiting broad substrate scope and wide functional-group compatibility. In addition, ortho-position selective C-H trifluoromethoxylation of pyridines is observed. The method is not only applicable to the gram-scale synthesis of trifluoromethoxylated products but also allows efficient late-stage C-H trifluoromethoxylation of marketed small-molecule drugs, common pharmacophores and natural products. Selective C-H trifluoromethoxylation of pyridines remains a formidable synthetic challenge. Here, the authors report a silver-mediated late-stage C-H trifluoromethoxylation of arenes and heteroarenes as limiting reagents with trifluoromethoxide anion.

The dependence of polymer film transparency on different kinds of planar orientations of nanoporous-crystalline (NC) phases of syndiotactic polystyrene (sPS) and poly(2,6-dimethyl-1,4-phenylene)oxide (PPO) is described. The two polymers exhibit opposite behavior: film transparency is improved for sPS and PPO by orientations of the chain axes of the NC phases being parallel (c(parallel to)) and perpendicular (c(perpendicular to)) to the film plane, respectively. This behavior can be rationalized by the negative and positive birefringence of sPS and PPO chains, respectively. In fact, to maximize transparency, the refractive index of the NC phase along the perpendicular to the film plane has to be increased to come closer to that of the corresponding amorphous phase. This can be pursued by controlling the orientation of the NC phases and hence of the associated refractive index ellipsoids.

Various optical clearing methods have emerged as powerful tools for deep biological imaging. Organic solvent-based clearing methods, such as three-dimensional imaging of solvent-cleared organs (3DISCO), present the advantages of high clearing efficiency and size reduction for panoptic imaging of large samples such as whole organs and even whole bodies. However, 3DISCO results in a rapid quenching of endogenous fluorescence, which has impeded its application. Here, we propose an advanced method named FDISCO to overcome this limitation. FDISCO can effectively preserve the fluorescence of various fluorescent probes and can achieve a long storage time of months while retaining potent clearing capability. We used FDISCO for high-resolution imaging and reconstruction of neuronal and vascular networks. Moreover, FDISCO is compatible with labeling by multiple viruses and enables fine visualization of neurons with weak fluorescence labeling in the whole brain. FDISCO represents an effective alternative to the three-dimensional mapping of whole organs and can be extensively used in biomedical studies.

We report on the shape, composition (from Pt95Zn5 to Pt77Zn23), and surface chemistry of Pt-Zn nanoparticles obtained by reduction of precursors M2+(acac) (-)(2) (M2+: Pt2+ and Zn2+) in oleylamine, which serves as both solvent and ligand. We show first that the addition of phenyl ether or benzyl ether determines the composition and shape of the nanoparticles, which point to an adsorbate-controlled synthesis. The organic (ligand)/inorganic (nanoparticles) interface is characterized on the structural and chemical level. We observe that the particles, after washing with ethanol, are coated with oleylamine and the oxidation products of the latter, namely, an aldimine and a nitrile. After exposure to air, the particles oxidize, covering themselves with a few monolayer thick ZnO film, which is certainly discontinuous when the particles are low in zinc. Pt-Zn particles are unstable and prone to losing Zn. We have strong indications that the driving force is the preferential oxidation of the less noble metal. Finally, we show that adsorption of CO on the surface of nanoparticles modifies the oxidation state of amine ligands and attribute it to the displacement of hydrogen adsorbed on Pt. All the structural and chemical information provided by the combination of electron microscopy and X-ray photoelectron spectroscopy allows us to give a fairly accurate picture of the surface of nanoparticles and to better understand why Pt-Zn alloys are efficient in certain electrocatalytic reactions such as the oxidation of methanol.

In-situ Raman spectroelectrochemistry is a powerful tool to understand the structures and reaction mechanisms of electrochemical interfaces yet usually suffers from a low sensitivity and detection efficiency. Herein, we develop a windowless thin layer electrochemical cell design to improve the detection efficiency of in-situ Raman spectroscopy for practical nanoscale electrocatalysts. This was achieved by perforating a hole in the optical window of the cell, which not only eliminates the refraction of light by the window but also induces a meniscus thin electrolyte layer on the working electrode, thus significantly improving the detection efficiency of Raman spectra. We successfully applied thismethod to conduct in-situ Raman spectroscopy of structural evolutions of two representative Ni-Fe oxide catalysts (layered double hydroxides and spinel oxides) during oxygen evolution reaction (OER) electrocatalysis. It was shown that both catalysts underwent surface transformation to oxyhydroxides and formed active oxygen species at OER relevant potentials. However, the extent of the surface transformation was much lower on the Ni-Fe spinel catalyst, accounting for its lower OER activity. We further show that adding a carbon support can promote the surface transformation of Ni-Fe spinel to oxyhydroxides, thus significantly increasing the electrocatalytic activities. The established windowless thin layer method provides a new way to conduct in-situ electrochemical Raman spectroscopy of a wide range of materials and may be also combined with surface-enhanced Raman spectroscopic methods.

In this study, a well-defined, novel NHC-Ni complex was developed and used to catalyze the N-arylation of alkyl- and arylamines with arylboronic acids in a rare version of Chan-Lam coupling. Although the same coupling using copper catalysts has been widely studied, the nickel-catalyzed version is rare and normally requires 10-20 mol% catalyst loading. This novel NHC-Ni complex in combination with 4,4′-dimethyl-2,2′-bipyridine, however, proved to be an effective catalyst that lowered the required catalyst loading to only 2.0 mol%.

Short-chain oxymethylene dimethyl ethers (OMEs) (molecular formula: H3CO-(CH2O)(n)-CH3, where n = 3-5) have previously been studied as diesel-like fuels and fuel additives. OMEs can be produced from sustainably sourced methanol, and tests indicate that they are neither genotoxic nor mutagenic. In this report, their potential as solvents has been investigated to expand the bio-derived solvent space. According to traditional solvatochromic parameters, a commercial mixture of OME3-5 and its individual components (OME3, OME4, and OME5) have solvation properties similar to problematic industrial ether solvents such as 1,4-dioxane. Peroxide formation, one of the chief dangers of classical ether solvents, was found to occur much more slowly in OMEs than in conventional solvents such as tetrahydrofuran (THE), demonstrating an improved safety profile. The commercial OME3-5 mixture was found to be broadly miscible with organic solvents but immiscible with water, suggesting potential application in aqueous extractions. It performed well in the dissolution of polystyrene and removal of paints and coatings, indicating OME3-5 may suitable to replace dichloromethane in polymer recycling, polymer welding, and cleaning applications. To further demonstrate applicability as a solvent, this mixture was shown to facilitate a model Suzuki coupling reaction at rates similar to cyclopentyl methyl ether, which is currently marketed as a green ether. Finally, OME3-5 proved a suitable solvent for enzymatic polymerization, giving high yields, moderately high degrees of polymerization, and remarkably narrow dispersity values.

In this study, the influence of grapefruit seed extract (GFSE) was studied on citric acid and zinc oxide incorporated cellulose-based hydrogel films. The effect of GFSE (0.25-1.0%, v/v) on hydrogel films was examined for their physico-chemical, mechanical, thermal, antioxidant and antibacterial properties. The swelling ratio, tensile strength and thermal stability of films decreased with increase in GFSE concentrations. On the other hand, elongation (%) and antioxidant activity of films were found to be 34-60% and 25-79%, respectively for increasing amounts of GFSE. FESEM and FETEM clearly showed that two different types of nanoparticles (50-90 nm and 5-10 nm) were present in GFSE incorporated films. The release of polyphenolic compounds and zinc from films was in sustained manner. Furthermore, the fabricated hydrogel films exhibited antibacterial activity against both E. coli and S. aureus. All these results indicate that the prepared nanocomposite hydrogel films could find their potential applications in wound healing.
