Quality Control of Bis(acetylacetone)copper And the article was included in Journal of Colloid and Interface Science in 2020. The article conveys some information:

Bornite (Cu5FeS4) exhibits great potential for the alk. hydrogen evolution reaction (HER) and few studies have been conducted on its electrocatalytic activity. Herein, we successfully fabricate NixS/Cu5FeS4hybrid catalyst with interface structure between NixS nanoparticles (NPs) and Cu5FeS4 NPs. The NixS/Cu5FeS4hybrid catalyst exhibits favorable HER performances in 1.0 M KOH electrolyte and demonstrates smaller overpotential and lower Tafel slope than bare NixS NPs and Cu5FeS4 NPs. The remarkable HER performances are attributed to the strongly coupling interface structure between NixS NPs and Cu5FeS4 NPs, which leads to synergistic effect optimizing the HER activity and enhancing the charge transfer during catalytic process. This work provides a promising strategy for the construction of Cu5FeS4-based hybrid catalyst and its application in energy systems.

《Binary Superlattices of Infrared Plasmonic and Excitonic Nanocrystals》 was published in ACS Applied Materials & Interfaces in 2020. These research results belong to Brittman, Sarah; Mahadik, Nadeemullah A.; Qadri, Syed B.; Yee, Patrick Y.; Tischler, Joseph G.; Boercker, Janice E.. Name: Bis(acetylacetone)copper The article mentions the following:

Self-assembled superlattices of nanocrystals offer exceptional control over the coupling between nanocrystals, similar to how solid-state crystals tailor the bonding between atoms. By assembling nanocrystals of different properties (e.g., plasmonic, excitonic, dielec., or magnetic), we can form a wealth of binary superlattice metamaterials with new functionalities. Here, we introduce IR plasmonic Cu2-xS nanocrystals to the limited library of materials that have been successfully incorporated into binary superlattices. We are the first to create a variety of binary superlattices with large excitonic (PbS) nanocrystals and small plasmonic (Cu2-xS) nanocrystals, both resonant in the IR. Then, by controlling the surface chem. of large Cu2-xS nanocrystals, we produced structurally analogous superlattices of large Cu2-xS and small PbS nanocrystals. Transmission electron microscopy (TEM) and grazing-incidence small-angle X-ray scattering (GISAXS) were used to characterize both types of superlattices. Furthermore, our unique surface modification of the large Cu2-xS nanocrystals also prevented them from chem. quenching the photoluminescence of the PbS nanocrystals, which occurred when the PbS nanocrystals were mixed with unmodified Cu2-xS nanocrystals. These synthetic achievements create a set of binary superlattices that can be used to understand how IR plasmonic and excitonic nanocrystals couple in a variety of symmetries and stoichiometries.

Formula: C10H16CuO4In 2021 ,《Spray synthesis of CuFeO2 photocathodes and in-operando assessment of charge carrier recombination》 was published in Journal of Physical Chemistry C. The article was written by Boudoire, Florent; Liu, Yongpeng; Le Formal, Florian; Guijarro, Nestor; Lhermitte, Charles R.; Sivula, Kevin. The article contains the following contents:

Semiconducting delafossite-phase CuFeO2 is a promising photocathode material for solar-driven hydrogen production given its suitable energy levels and established robustness for photoelectrochem. water reduction Nevertheless, reported methods for preparing CuFeO2 thin films are cumbersome, and an explanation for the observed poor performance of this material remains under debate. Herein, a facile and scalable deposition method based on aerosol-assisted chem. vapor deposition of CuFeO2 photocathodes is reported. Optimization of deposition conditions reveals that larger grain size is beneficial for photoelectrochem. operation. Extensive photoelectrochem. testing including illumination and potential modulation spectroscopy of these photocathodes under nonsacrificial operation conditions indicates solar photocurrent densities up to 2.5 mA cm-2. The bulk charge separation efficiency and the interfacial charge injection efficiency at +0.4 V vs RHE are estimated to be 11% and 0.8%, resp. This establishes that, while bulk photogenerated charge carrier recombination in CuFeO2 remains an important loss, the performance bottleneck of CuFeO2 for H2 production is clearly due to surface recombination.

In 2022,Li, Siyi; Ding, He; Chang, Jinhu; Dong, Shuming; Shao, Boyang; Dong, Yushan; Gai, Shili; He, Fei; Yang, Piaoping published an article in Journal of Colloid and Interface Science. The title of the article was 《Bimetallic oxide nanozyme-mediated depletion of glutathione to boost oxidative stress for combined nanocatalytic therapy》.Quality Control of Bis(acetylacetone)copper The author mentioned the following in the article:

Although nanocatalytic therapy has become an emerging strategy for tumor treatment, the therapeutic effects of reactive oxygen species (ROS)-mediated treatment are still seriously limited by the inherent flaws of the enzymic activities and the specific physicochem. properties of the tumor microenvironment (TME). Herein, we report an ultrasmall bimetallic oxide nanozyme (CuFe2O4@PEG, CFOs) for programmable multienzyme-like activities-primed combined therapy. Under the acidic condition, abundant highly toxic ROS can be generated through the peroxidase activity of CFOs with overexpressed hydrogen peroxide (H2O2) in the tumor. High metal ion utilization of bimetallic oxide nanozymes is related to the size effect and topol. structure. Furthermore, glutathione peroxidase activity-initiated depletion of GSH disrupts the intracellular antioxidant defense system and further amplifies the oxidative stress in turn. Subsequently, oxygen generation originating from the catalase activity of CFOs relieves tumor hypoxia and achieves exceptional TME-customized therapeutic effects. Notably, the high photothermal effect (η = 41.12%) of CFOs in the second near-IR biol. windows leads to the combinational inhibition of tumor growth. In summary, this report provides a paradigm for the rational design of TME-responsive and ROS-mediated nanocatalytic treatment, which is promising for achieving superior therapeutic efficiency.

The article was titled 《Enhancing the photocatalytic reduction of CO2 with undoped and Cu-doped TiO2 nanofibers synthesized in supercritical medium》. The information in the text is summarized as follows:

The photocatalytic reduction of CO2 with water vapor using titania nanofibers (TNFs) synthesized in supercritical medium has been assessed. TNFs have been produced from titanium isopropoxide (TTIP) precursor at different pressures (200-240 bar) and temperatures (40-80°C). Synthesized materials were later characterized by scanning and transmission electron microscopy, BET surface area anal., X-ray diffraction, and UV-vis diffuse reflectance spectroscopy. Better defined morphologies were obtained at the highest pressure and temperatures tested, so the catalyst synthesized at 240 bar and 60°C was doped with copper (0.4-2 weight %) in order to study the influence of metal doping on CO2 reduction All undoped and Cu-doped TNFs have been found to exhibit higher CO2 reduction rates than com. catalyst (P-25) and other TNF-based catalysts produced with traditional methods, although methane and CO remain the only two reaction products. Moreover, it has been found that copper doping improves CO2 conversion in comparison with the equivalent undoped catalyst.

《ZnO-CuO Core-Hollow Cube Nanostructures for Highly Sensitive Acetone Gas Sensors at the ppb Level》 was written by Lee, Jae Eun; Lim, Chan Kyu; Park, Hyung Ju; Song, Hyunjoon; Choi, Sung-Yool; Lee, Dae-Sik. Category: copper-catalystThis research focused onzinc copper oxide shell hollow nanocube acetone gas sensor; acetone detection; hybrid nanostructure; metal oxide semiconductor; p−n junction; ultrasensitive gas sensor. The article conveys some information:

This paper presents a ZnO-CuO p-n heterojunction chemiresistive sensor that comprises CuO hollow nanocubes attached to ZnO spherical cores as active materials. These ZnO-CuO core-hollow cube nanostructures exhibit a remarkable response of 11.14 at 1 ppm acetone and 200°C, which is a superior result to those reported by other metal-oxide-based sensors. The response can be measured up to 40 ppb, and the limit of detection is estimated as 9 ppb. ZnO-CuO core-hollow cube nanostructures also present high selectivity toward acetone against other volatile organic compounds and demonstrate excellent stability for up to 40 days. The outstanding gas-sensing performance of the developed nanocubes is attributed to their uniform and unique morphol. Their core-shell-like structures allow the main charge transfer pathways to pass the interparticle p-p junctions, and the p-n junctions in each particle increase the sensitivity of the reactions to gas mols. The small grain size and high surface area of each domain also enhance the surface gas adsorption.

Pesesse, Antoine; Carenco, Sophie published an article in 2021. The article was titled 《Influence of the copper precursor on the catalytic transformation of oleylamine during Cu nanoparticle synthesis》, and you may find the article in Catalysis Science & Technology.Application In Synthesis of Bis(acetylacetone)copper The information in the text is summarized as follows:

For optimal use of copper nanoparticles in catalysis, in-depth understanding of the reaction mechanisms and fine characterization of final products are equally relevant. Indeed, both have a direct impact on the nanoparticle core and surface. So far, most insights come from characterization techniques focusing on the inorganic component, i.e. the nanoparticle core. Mol. techniques are often overlooked and the reactions alongside the reduction of the copper precursor are not properly understood. Such understanding is mandatory to properly interpret the nanoparticle behavior in catalytic processes. Here, copper nanoparticle synthesis was studied by thorough characterization of the organic reactions happening during the synthesis, quant. by 1H NMR and qual. by infra-red spectroscopy (IR) and electrospray ionisation-mass spectrometry (ESI-MS). The reduction of copper(II) acetate (Cu(OAc)2) by oleylamine resulted in a high amount of water and few byproducts while the reduction of copper(II) acetylacetonate (Cu(acac)2) resulted in a low amount of water and many products. The resulting nanoparticles showed different abilities to further dehydrogenate and transaminate oleylamine in the synthesis reaction pot. This was explained by the presence of a copper oxide phase in the nanoparticles prepared from copper acetate.

Li, Jiaxiong; Ren, Chao; Sun, Zhijian; Ren, Yanjuan; Lee, Haksun; Moon, Kyoung-sik; Wong, Ching-Ping published an article in 2021. The article was titled 《Melt Processable Novolac Cyanate Ester/Biphenyl Epoxy Copolymer Series with Ultrahigh Glass-Transition Temperature》, and you may find the article in ACS Applied Materials & Interfaces.SDS of cas: 13395-16-9 The information in the text is summarized as follows:

The rapid progress in silicon carbide (SiC)-based technol. for high-power applications expects an increasing operation temperature (up to 250°C) and awaits reliable packaging materials to unleash their full power. Epoxy-based encapsulant materials failed to provide satisfactory protection under such high temperatures due to the intrinsic weakness of epoxy resins, despite their unmatched good adhesion and processability. Herein, we report a series of copolymers made by melt blending novolac cyanate ester and tetramethylbiphenyl epoxy (NCE/EP) that have demonstrated much superior high-temperature stability over current epoxies. Benefited from the aromatic, rigid backbone and the highly functional nature of the monomers, the highest values achieved for the copolymers are as follows: glass-transition temperature (Tg) above 300°C, decomposition onset above 400°C, and char yield above 45% at 800°C, which are among the highest of the known epoxy chem. by far. Moreover, the high-temperature aging (250°C) experiments showed much reduced mass loss of these copolymers compared to the traditional high-temperature epoxy and even the pure NCE in the long term by suppressing hydrolysis degradation mechanisms. The copolymer composition, i.e., NCE to EP ratio, has found to have profound impacts on the resin flowability, thermomech. properties, moisture absorption, and dielec. properties, which are discussed in this paper with in-depth anal. on their structure-property relationships. The outstanding high-temperature stability, preferred and adjustable processability, and the dielec. properties of the reported NCE/EP copolymers will greatly stimulate further research to formulating robust epoxy molding compounds (EMCs) or underfill for packaging next-generation high-power electronics.

《Low Pt-Content Ternary PtNiCu Nanoparticles with Hollow Interiors and Accessible Surfaces as Enhanced Multifunctional Electrocatalysts》 was written by Wu, Dengfeng; Zhang, Wei; Lin, Aijun; Cheng, Daojian. Category: copper-catalyst And the article was included in ACS Applied Materials & Interfaces in 2020. The article conveys some information:

Developing highly active and durable electrocatalysts with low levels of Pt content toward some crucial reactions including O reduction reaction, H evolution reaction, and MeOH oxidation reaction in an acidic electrolyte environment are desirable but still an open challenge for clean and efficient energy conversion. Herein, the authors present a facile route to synthesize low Pt-content ternary PtNiCu nanostructures with hollow interior and accessible surfaces (H-PtNiCu-AAT NPs) as enhanced multifunctional electrocatalysts. The galvanic replacement reaction and at. diffusion between in situ preformed CuNi nanocrystals and Pt species should be responsible for the formation of hollow PtNiCu NPs. Continuous activation by acid picking and annealing treatments were performed to leach out the excessive Cu and Ni on the surfaces and to enrich Pt-content on the surface. H-PtNiCu-AAT NPs exhibit excellent activity and durability toward HER, ORR, and MOR due to the rational integration of multiple structural advantages. Strikingly, the mass activity and specific activity of H-PtNiCu-AAT NPs (0.977 A mgPt-1 and 1.458 mA cm-2) is 7.1 and 6.9 times higher than that of com. Pt/C (0.138 A mgPt-1 and 0.212 mA cm-2) toward ORR at 0.9 V (vs. RHE), resp. This present work provides an efficient strategy for the design of low Pt-content trimetallic electrocatalysts with excellent activity and durability.
