Catalysts containing isolated single atoms have attracted much interest due to their good catalytic behavior, bridging the gap between homogeneous and heterogeneous catalysts. Here, we report an efficient oxygen reduction reaction (ORR) catalyst that consists of atomically dispersed single copper sites confined by defective mixed-phased TiO2-x. This synergistic catalyst was produced by introducing Cu2+ to a metal organic framework (MOF) using the Mannich reaction, occurring between the carbonyl group in Cu(acac)2 and the amino group on the skeleton of the MOF. The embedding of single copper atoms was confirmed by at.-resolution high-angle annular dark-field scanning transmission electron microscopy and x-ray absorption fine structure spectroscopy. Electronic structure modulation of the single copper sites coupling with oxygen vacancies was further established by ESR spectroscopy and first-principles calculations Significantly enhanced ORR activity and stability were achieved on this special Cu single site. The promising application of this novel electrocatalyst was demonstrated in a prototype Zn-air battery. This strategy of the stabilization of single-atom active sites by optimization of the at. and electronic structure on a mixed matrix support sheds light on the development of highly efficient electrocatalysts.

The article was titled 《Hole mobility improvement in Cu2O thin films prepared by the mist CVD method》. The information in the text is summarized as follows:

A high-mobility Cu2O thin film was fabricated using the mist chem. vapor deposition (CVD) method. This was achieved by suppressing the contamination from nitrogen impurities and optimum growth conditions to obtain single-phase Cu2O without CuO. A 600 nm Cu2O thin film was obtained using EDTA as a complexing agent in dry-air growth atm. for 120 min. The resulting thin film had a resistivity of 2.8 × 102 Ω ·cm, carrier concentration of 1.2 × 1015 cm-3 and hole mobility of 19.3 cm2·V-1·s-1. This hole mobility improved by two or more orders of magnitude compared to that of previous Cu2O thin film obtained by the mist CVD method.

Synthetic Route of C10H16CuO4. The article was titled 《Bis-copper(II) Complex of Triply-linked Corrole Dimer and Its Dication》. The information in the text is summarized as follows:

Copper complexes of corroles have recently been a subject of keen interest due to their ligand noninnocent character and unique redox properties. Here the authors studied bis-copper complex of a triply-linked corrole dimer that serves as a pair of divalent metal ligands but can be reduced to a pair of trivalent metal ligands. Reaction of triply-linked corrole dimer 2 with Cu(acac)2 (acac = acetylacetonate) gave bis-copper(II) complex 2Cu as a highly planar mol. with a mean-plane deviation value of 0.020 Å, where the two copper ions were revealed to be divalent by ESR, SQUID, and XPS methods. Oxidation of 2Cu with two equivalent of AgBF4 gave complex 3Cu, which was characterized as a bis-copper(II) complex of a dicationic triply-linked corrole dimer not as the corresponding bis-copper(III) complex. In accord with this assignment, the structural parameters around the copper ions were revealed to be quite similar for 2Cu and 3Cu. Importantly, the magnetic spin-spin interaction differs depending on the redox-state of the ligand, being weak ferromagnetic in 2Cu and antiferromagnetic in 3Cu.Bis(acetylacetone)copper(cas: 13395-16-9Synthetic Route of C10H16CuO4) was used in this study.

Safety of Bis(acetylacetone)copperIn 2019 ,《Classes of non-conventional tetraspanins defined by alternative splicing》 was published in Scientific Reports. The article was written by Hochheimer, Nikolas; Sies, Ricarda; Aschenbrenner, Anna C.; Schneider, Dirk; Lang, Thorsten. The article contains the following contents:

Tetraspanins emerge as a family of membrane proteins mediating an exceptional broad diversity of functions. The naming refers to their four transmembrane segments, which define the tetraspanins’ typical membrane topol. In this study, we analyzed alternative splicing of tetraspanins. Besides isoforms with four transmembrane segments, most mRNA sequences are coding for isoforms with one, two or three transmembrane segments, representing structurally mono-, di- and trispanins. Moreover, alternative splicing may alter transmembrane topol., delete parts of the large extracellular loop, or generate alternative N- or C-termini. As a result, we define structure-based classes of non-conventional tetraspanins. The increase in gene products by alternative splicing is associated with an unexpected high structural variability of tetraspanins. We speculate that non-conventional tetraspanins have roles in regulating ER exit and modulating tetraspanin-enriched microdomain function.Bis(acetylacetone)copper(cas: 13395-16-9Safety of Bis(acetylacetone)copper) was used in this study.

Torras, Miquel; Roig, Anna published their research in Crystal Growth & Design in 2021. The article was titled 《Copper Oxide Nanocubes Wrapping Metals by Microwave Synthesis》.Safety of Bis(acetylacetone)copper The article contains the following contents:

Copper and copper oxide nanoparticles (NPs) are industrially important. In particular, Cu-based nanocatalysts find applicability in electrocatalysis and photocatalysis, profiting from the accessible oxidation states of copper and a band gap in the visible region of the Cu2O phase. However, in this case, the fast recombination of the charge carriers compromises the final photocatalytic efficiency. The combination of Cu2O with metals often results in higher and more stable photocatalytic efficiency. Here, the fabrication of noble metal NPs [Au, Ag, Pd, and Pt] and Cu2O heterostructures (HSs) by a microwave (MW)-assisted synthesis is presented. The selectivity of the MW technique with a fast two-step protocol enabled us to easily prepare these multicomponent nanoparticles in a short time (~40 min). First, metal NPs (Au, Ag, or Pd) are synthesized through a MW-assisted polyol approach, and these NPs serve as nucleation seeds for cubic Cu2O wrapping. Other types of heterostructures were found when using smaller Pt NPs instead. Focusing on Au NPs as the core, we analyzed the effect of the gold to copper molar ratio on the shape yield of the nanocubes, reported their optic and plasmonic properties, and demonstrated the reproducibility and scalability of the synthetic routes. Here, we are providing a pioneering example of MW heating as a non-conventional energy source for a general chem. approach to attain a family of complex metal/metal oxide heterostructures.Bis(acetylacetone)copper(cas: 13395-16-9Safety of Bis(acetylacetone)copper) was used in this study.

Computed Properties of C10H16CuO4This research focused onzinc oxide copper fabrication lithium ion electrode. The article conveys some information:

Designing electrodes with tailored architecture is an efficient mean to enhance the performance of metal-ion batteries by minimizing electronic and ionic transport limitations and increasing the fraction of active material in the electrode. However, the fabrication of architectured electrodes often involves multiple laborious steps that are not directly scalable to current manufacturing platforms. Here, we propose a processing route in which Cu-coated ZnO powders are directly shaped into architectured electrodes using a simple uniaxial pressing step. Uniaxial pressing leads to a percolating Cu phase with enhanced elec. conductivity between the active ZnO particles and improved mech. stability, thus dispensing the use of carbon-based additives and polymeric binders in the electrode composition The additive-free percolating copper network obtained upon pressing leads to highly loaded integrated anodes displaying volumetric charge capacity 6-10 fold higher than Cu-free ZnO films and that matches the electrochem. performance reported for advanced cathode structures. Achieving this high charge capacity using a readily available pressing tool makes this approach a promising route for the facile manufacturing of high-performance electrodes at large industrial scales.

Pt-based nanostructures with low Pt content are attractive electrocatalysts for high-efficiency hydrogen evolution reaction. It’s a challenge to simultaneously tailor the structure and size of Pt-based alloys in a simple manner and boost their electrocatalytic efficiency. Here, we report the synthesis of high performance Fe45Pt35Cu20 nanoparticles (NPs) with a well-controlled size and crystal structure by a simple organometallic method. Size control of the particles was realized in the range of 8 nm to 27 nm by simply varying the type of Fe precursor, and with the increase of particle size the Fe45Pt35Cu20 alloys exhibited a higher degree of chem. ordering (fct phase, namely L10 structure). The FePtCu nanoparticles showed superior catalytic activity and stability towards the hydrogen evolution reaction with a notably low Tafel slope of 24 mV dec-1 (0.5 M H2SO4) in comparison to com. Pt/C catalysts. The work provides a simple strategy for tailoring the size and crystal phase of Pt based nanostructures to facilitate their promising application in catalytic reactions.

Intermetallic phases in Au-Cu nanoparticles has been synthesized chem. in liquid phase. The heat-treatment of these nanoparticles at 180°C for 1 h in solution phase led to the formation of Au-Cu alloy nanoparticles with nearly spherical shapes and monodispersed size of ∼10 nm. Subsequent heat-treatment at 300°C for 30 min of these Au-Cu alloy nanoparticles not only revealed structural transformation to intermetallic phases (tetragonal AuCu (tP4) and cubic Cu3Au (cP4)) but also shape change occurs from spherical to rods having average aspect ratio ∼3.0. The structural determination at the particle has been carried out through nano-beam electron diffraction coupled with simulation of electron diffraction patterns and high resolution phase contrast images. These Au-Cu intermetallic nanoparticles exhibit an excellent surface enhanced Raman spectroscopic activity with methylene blue compared to that of Au-Cu alloy nanoparticles.

Transition metal Cu nanocrystals have shown promising prospects for degrading organic pollutants. Herein, high-efficiency Fe3O4-Cu nanocomposites (NCs) have been successfully synthesized though a facile one-step thermal decomposition method. With a turnover frequency of 6.4 min-1, our Fe3O4-Cu NCs (heated temperature: 225°C) could degrade the 4-nitrophenol in less than 15 s and showed almost unchanged catalytic efficiency (>90%) after recycled reactions up to six times. Furthermore, the influence of the heat treatment on the structure, elemental distribution, magnetic property and catalytic performance of Fe3O4-Cu NCs was investigated. As the temperature increased from 225°C to 285°C, the saturation magnetization of Fe3O4-Cu NCs decreased from 7.27 to 26.2 emu/g, owing to the enlarged mass ratio of Fe3O4 nanocrystals: Cu nanocrystals. This work provides the practical design guidance to the large-scale fabrication of high-efficiency and low-cost Fe3O4-Cu NCs catalysts, which shows promising future for degrading the nitro compounds in wastewater.

《Predicting the solubilities of metal acetylacetonates in supercritical CO2: Thermodynamic approach using PC-SAFT》 was written by Ushiki, Ikuo; Fujimitsu, Ryo; Takishima, Shigeki. Application of 13395-16-9 And the article was included in Journal of Supercritical Fluids in 2020. The article conveys some information:

Solubilities of metal precursors in supercritical carbon dioxide (scCO2) are needed to effectively design the scCO2-based deposition method. Herein, a method for predicting the solubilities of metal acetylacetonate (acac) precursors in scCO2 was developed using the perturbed-chain statistical associating fluid theory (PC-SAFT) equation of state. Three PC-SAFT pure-component parameters viz., the segment diameter, segment number, and dispersion energy, for two metal acetylacetonates (Cr(acac)3 and Cu(acac)2) were determined by adjusting their values to the measured solubilities in organic solvents. The PC-SAFT parameters of Cr(acac)3 and Cu(acac)2 were then applied to predict the exptl. determined metal precursor solubilities in scCO2 from the literature. The PC-SAFT predictions accurately described the exptl. solubilities in scCO2 over a wide range of pressures and temperatures even if the binary interaction parameter kij was set to 0. The isobaric solubilities in scCO2 were also calculated with the generalized kij values, which provided a successful PC-SAFT description.
