Copper thin films prepared by chemical vapour deposition from copper (II) acetylacetonate

Copper thin films were prepared by a low-temperature atmospheric pressure chemical vapour deposition method. The raw material was copper (II) acetylacetonate. At a reaction temperature above 220 C, polycrystalline copper films can be obtained by hydrogen reduction of the raw material. The resistivity of the film was close to that for bulk copper.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 13395-16-9 is helpful to your research. Reference of 13395-16-9

High-efficiency perovskite solar cell using cobalt doped nickel oxide hole transport layer fabricated by NIR process

Lead halide perovskite solar cells (PVSCs) have potential toward commercialization because of their high efficiency and low cost. The hole transport layer (HTL) of p-i-n perovskite solar cell is usually made of NiOX. However, the NiOX needs to be processed at 300 C for 15 min for good hole transport property. This long heating time prohibits the development of continuous commercial process. Thus, a rapid heating process for the NiOX film deposition is critical to realize the commercialization of PVSCs in the future. In this study, we develop a facile method to obtain high quality NiOX films annealed by NIR in a short time of 50 s. A short-wave NIR lamp at 2500 K was used to systematically investigate the effect of NIR intensity on the film quality of sol-gel NiOX. The PVSCs fabricated from NIR-annealed NiOX (NIR-NiOX) film show a comparable power conversion efficiency (PCE) to those fabricated from traditional hot-plate annealed-NiOX (HP-NiOX). In addition, the NIR annealed cobalt-doped NiOX (NIR-Co:NiOX) was synthesized to replace pristine NIR-NiOX. The PCE of PVSCs fabricated from this new NiOX film can be increased from 15.99% to 17.77%, which is due to the efficient hole extraction, less charge accumulation, and reducing Voc loss resulting from the improved hole mobility, reduced interface resistance and well-matched work function. Our study paves a way to fulfill the requirements of low cost and low energy consumption of large scale production of high efficiency PVSCs.

One-pot synthesis of (ethoxycarbonyl)difluoromethylthioethers from thiocyanate sodium and ethyl 2-(trimethylsilyl)-2,2-difluoroacetate (TMS-CF2CO2Et)

An efficient one-pot cascade methodology for the synthesis of (ethoxycarbonyl)difluoromethyl thioethers is described. Benzyl, allyl, alkyl halides or diazonium salts as the starting materials together with thiocyanate sodium and TMS-CF2CO2Et in the presence of CsF or NaOAc afford a variety of the fluoroalkylthiolated products in moderate to good yields.

Luminescent dipyrrinato complexes of trivalent group 13 metal ions

Although free dipyrrins (dipyrromethenes) do not strongly luminesce, certain dipyrrinato complexes of BF2 and zinc(II) are known to be intensely luminescent species. Two new dipyrrinato fluorophores, based on complexes with gallium(III) and indium(III), are described. Using a previously described meso-mesityl-substituted dipyrrin, namely 5-mesityldipyrrin (mesdpm), the complexes [Ga(mesdpm)3] and [In(mesdpm)3] were prepared and structurally characterized. The complexes display the expected octahedral geometry about the metal ions. In some solvents, such as hexanes, the complexes emit green light upon excitation with UV light at room temperature, with quantum yields of 2.4% ([Ga(mesdpm)3]) and 7.4% ([In(mesdpm)3]) and lifetimes in the low nanosecond range. Observations are consistent with assignment to ligand-localized transitions, and this interpretation is further confirmed by density functional calculations described herein. The new complexes are important additions to the widely used family of dipyrrin-based fluorescent species and show that dipyrrinato complexes containing metals other than BF2 and zinc(II) may be useful fluorophores.

Triboluminescent Electrospun Mats with Blue-Green Emission under Mechanical Force

Fibrous mechanosensing elements can provide information about the direction of crack propagation and the mechanism of material failure when they are homogeneously dispersed into the bulk volume of materials. A fabrication strategy of fibrous systems showing triboluminescent (TL) responses is in high demand for such applications. In this work, micrometer-sized Cu(NCS)(py)2(PPh3) crystals were synthesized, and polymeric fibrous mats containing the TL crystals were obtained via electrospinning as a stress probe for the determination of mechanical impact. Four different polymeric systems have been employed (PMMA, PS, PU, and PVDF), and the mechano-optical sensing performance of electrospun mats of the polymer-crystal composites was measured. Photophysical properties (quantum yield, band gap, and broadness of the emission) of the TL crystal/electrospun mat composites were also studied. TL and PL emission maxima of the PU-based composite mat show identical behavior due to the chemical affinity between the two structures and the smallest fiber diameter. Moreover, the PU fiber mats exhibit long-lived bluish-green emission persisting over a large number of drops.

Abstract A new method has been developed for the copper-mediated trifluoromethylthiolation of allylic halides by using potassium fluoride, elemental sulfur, and (trifluoromethyl)trimethylsilane in anhydrous N,N-dimethylformamide. This protocol provides facile access to a variety of allylic trifluoromethyl thioethers in moderate to good yields under mild, ligand-free reaction conditions.

An IrRu alloy nanocactus on Cu2-xS@IrSy as a highly efficient bifunctional electrocatalyst toward overall water splitting in acidic electrolytes

Development of highly active and durable bifunctional electrocatalysts for overall water splitting is vital for the economical production of H2 as an alternative energy source. Herein, we report the synthesis of Cu2-xS@IrSy@IrRu nanoparticles (CIS@IrRu NPs), which show excellent catalytic performances for both the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in an acidic electrolyte. Benefiting from the optimal composition of IrRu and the stable IrSy shell, the cactus-like IrRu NPs show high electrocatalytic activity and stability. The cactus-like IrRu NPs exhibit optimal HER and OER performances and high stability at a ratio of Ir/Ru 1.00:1.07. In overall water splitting, the CIS@Ir48Ru52 NPs achieve a current density of 10 mA cm-2 at a cell voltage of only 1.47 V in 0.1 M HClO4 electrolyte and show negligible degradation after 100 h of continuous operation in the stability test.
