Chemistry graduates have much scope to use their knowledge in a range of research sectors, including roles within chemical engineering, chemical and related industries, healthcare and more. Quality Control of Bis(acetylacetone)copper. Introducing a new discovery about 13395-16-9, Name is Bis(acetylacetone)copper, The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis.

Cu2ZnSnS4 (CZTS) compound semiconductor has the advantage of good matching with solar radiation in optical band-gap, large absorption coefficient, non-toxic and especially large abundance ratios of elements, so that CZTS has been considered as a good absorber layer used for the thin-film solar cells with most industrialization promising and environment friendly. In the present work, colloidal CZTS nanocrystals (average size ~8-16 nm) with the band gap of ~1.5 eV were synthesized via wet-chemical processing, using oleylamine (OLA) as solvent and capping molecules. The colloids were characterized by X-ray diffraction (XRD), Raman spectroscopy, transmission electron microscopy (TEM), scanning electron microscopy (SEM) and UV-Vis-NIR spectroscopy. The structure and morphology of nanocrystals were influenced with the reaction temperature. The resulting nanocrystals were kesterite-phase CZTS when the reaction temperature was lower, but were wurtzite-phase CZTS when the reaction temperature above 275 C. The CZTS films on glass substrates were prepared by drop-casting, from the colloidal 10 wt% CZTS-toluene solution where the CZTS colloids were synthesized at 260 C with three different recipes. The resulting films with different heat-treatments were investigated by XRD, SEM and energy dispersive spectroscopy (EDS). Densified CZTS films (5 lm in thickness) could be obtained by drying and sintering in vacuum. The CZTS films have the band-gap around 1.6-2.0 eV, due to Zn rich and S poor in the films. The dark conductivity and photoconductivity under AM 1.5 irradiation of the CZTS films on ITO glass substrates with different heat-treatments were measured by the AC impedance method.

A new method was developed for the determination of cefradine by extraction-flotation of CuSCN. The experiment indicated that in the presence of 0.20 mol/L NaOH the degradation of cefradine took place in water bath at 100 C. The thiol group (-SH) of the degradation product could reduce Cu(II) to Cu(I) for the formation of the emulsion CuSCN in the presence of NH4SCN at pH 4.0. By determining the residual amount of Cu(II) in the solution and calculating the flotation yield of Cu(II), the indirect determination of cefradine can be obtained. This method has been applied to determine cefradine in capsules, human serum and urine samples, respectively.

Lead halide perovskite solar cells have rapidly achieved high efficiencies comparable to established commercial photovoltaic technologies. The main focus of the field is now shifting toward improving the device lifetime. Many efforts have been made to increase the stability of the perovskite compound and charge-selective contacts. The electron and hole selective contacts are responsible for the transport of photogenerated charges out of the solar cell and are in intimate contact with the perovskite absorber. Besides the intrinsic stability of the selective contacts themselves, the interfaces at perovskite/selective contact and metal/selective contact play an important role in determining the overall operational lifetime of perovskite solar cells. This review discusses the impact of external factors, i.e., heat, UV-light, oxygen, and moisture, and measured conditions, i.e., applied bias on the overall stability of perovskite solar cells (PSCs). The authors summarize and analyze the reported strategies, i.e., material engineering of selective contacts and interface engineering via the introduction of interlayers in the aim of enhancing the device stability of PSCs at elevated temperatures, high humidity, and UV irradiation. Finally, an outlook is provided with an emphasis on inorganic contacts that is believed to be the key to achieving highly stable PSCs.

Reactions of a tungsten trisulfido complex of hydridotris(3,5- dimethylpyrazol-1-yl)borate (Tp*) [Et4N][Tp*WS 3] (1) with 3 equiv of CuCl in CHCl3 afforded a tetranuclear anionic cluster [Et4N][Tp*W(mu3-S) 3(CuCl)3] (2), while that of 1 with 3 equiv of CuNCS in MeCN produced a decanuclear neutral cluster (major product) [Tp*W(mu3-S)3Cu3(mu-NCS) 3(CuMeCN)]2 (3) along with a binuclear anionic cluster (minor product) [Et4N][Tp*WO(mu-S)2(CuNCS)] (4). Solvothermal reactions of 1 with 3 equiv of CuCN in MeCN at 80C for 48 h followed by slowly cooling it to ambient temperature gave rise to a polymeric cluster [Tp*W(mu3-S)(mu-S)2Cu 2(MeCN)(mu-CN)]n (5). Compounds 2-5 were characterized by elemental analysis, IR, UV-vis, 1H NMR, and single-crystal X-ray crystallography. The cluster anion of 2 has a [Tp*WS3Cu 3] incomplete cube with one Cl atom coordinated at each Cu center. 3 is composed of an unprecedented centrosymmetric W2Cu8 cluster core in which each void of the two single incomplete cubane-like [Tp*W(mu3-S)3Cu3(mu-NCS)] + cations is partially filled with an extra [Cu(MeCN)(mu-NCS) 2]- anion via a pair of Cu-mu-NCS-Cu bridges. The cluster anion of 4 contains one WS2Cu core that is formed by an oxidized [Tp*WO-(mu-S)2] species and one CuNCS fragment. 5 consists of butterfly shaped [Tp*W(mu3-S)(mu-S) 2Cu2(MeCN)] fragments that are interconnected via cyanide bridges to form a 1D spiral chain extending along the c axis. The successful synthesis of 2-5 from 1 suggests that 1 may be an excellent synthon to the W/Cu/S clusters. In addition, the third-order nonlinear optical (NLO) properties of 1-3 in solution were also investigated by femtosecond degenerate four-wave mixing (DFWM) technique with a 80 fs pulse width at 800 nm. Although 2 was not detected to have NLO effects, 1 and 3 exhibited relatively good optical nonlinearities with the nonlinear refractive index n2 and the third-order nonlinear optical susceptibility chi(3) values being 0.79 × 10-13 and 0.38 × 10-14 esu (1) and 2.08 × 10-13 and 1.00 × 10-14 esu (3), respectively. The second-order hyperpolarizability gamma value for 3 (5.46 × 10-32 esu) is ca. 5 times larger than that of its precursor 1.

CF3S, CF3 and HCF2 groups have been identified as valuable functionalities for drug development. Despite significant accomplishments in the trifluoromethylthiolation, trifluoromethylation and difluoromethylation reactions, directly converting common functional groups into CF3S, CF3 or HCF2 groups is still highly desirable. Described here is the dehydroxylative trifluoromethylthiolation, trifluoromethylation and difluoromethylation of alcohols promoted by a R3P/ICH2CH2I system. All of these dehydroxylative reactions were achieved under mild conditions via the activation of the hydroxyl group by the R3P/ICH2CH2I system. A wide substrate scope and good functional group tolerance were observed.

Stabilizing a 3d-transition metal component M from an MPd alloy structure in an acidic environment is key to the enhancement of MPd catalysis for various reactions. Here we demonstrate a strategy to stabilize Cu in 5 nm CuPd nanoparticles (NPs) by coupling the CuPd NPs with perovskite-type WO2.72 nanorods (NRs). The CuPd NPs are prepared by controlled diffusion of Cu into Pd NPs, and the coupled CuPd/WO2.72 are synthesized by growing WO2.72 NRs in the presence of CuPd NPs. The CuPd/WO2.72 can stabilize Cu in 0.1 M HClO4 solution and, as a result, they show Cu, Pd composition dependent activity for the electrochemical oxidation of formic acid in 0.1 M HClO4 + 0.1 M HCOOH. Among three different CuPd/WO2.72 studied, the Cu48Pd52/WO2.72 is the most efficient catalyst, with its mass activity reaching 2086 mA/mgPd in a broad potential range of 0.40 to 0.80 V (vs RHE) and staying at this value after the 12 h chronoamperometry test at 0.40 V. The synthesis can be extended to obtain other MPd/WO2.72 (M = Fe, Co, Ni), making it possible to study MPd-WO2.72 interactions and MPd stabilization on enhancing MPd catalysis for various chemical reactions.

Reactions of (NH4)2MS4 or (NH4)MOS3 (M = Mo, W) with CuSCN and the closo carborane diphosphine 1,2-(PPh2)2-1,2-C2B10H10 in CH2Cl2 yielded five heterobimetallic trinuclear Mo(W)-Cu-S clusters with the formula Cu2MS4L2 (M = Mo(1), W(3), L = 1,2-(PPh2)2-1,2-C2B10H10), Cu2MoS4L2 · CH2Cl2 (2) and Cu2MOS3L2 (M = Mo(4),W(5)). All the clusters have been characterized by elemental analysis, FT-IR, UV/Visible, 1H and 13C NMR spectroscopy and X-ray structure determination. X-ray crystal structure analysis showed that the metal skeleton of these clusters could be classified into two types. With (NH4)2MS4 (M = Mo, W), the three metal atoms (two Cu atoms and one M atom (M = Mo, W)) are almost in a linear conformation, while with (NH4)2MOS3 the conformation of the heterobimetallic trinuclear cluster core was a butterfly-shaped (or referenced as defective cubane-like with two corners missing). The coordination sphere of the metal atoms in all the clusters, either for Cu or M, should be described as a distorted tetrahedron. For each cluster, the closo carborane diphosphine ligand 1,2-(PPh2)2-1,2-C2B10H10 was introduced into the Cu2MS4 or Cu2MOS3 cluster cores and coordinated bidentately through the P atoms to Cu(I), and this resulted in a stable five-member chelating ring between the bis-diphosphine ligand and the metal.
