《Epitaxial mist chemical vapor deposition growth and characterization of Cu3N films on (0001)α-Al2O3 substrates》 was written by Yamaguchi, Tomohiro; Nagai, Hiroki; Kiguchi, Takanori; Wakabayashi, Nao; Igawa, Takuto; Hitora, Toshimi; Onuma, Takeyoshi; Honda, Tohru; Sato, Mitsunobu. Name: Bis(acetylacetone)copper And the article was included in Applied Physics Express in 2020. The article conveys some information:

Epitaxial growth of Cu3N films on (0001)α-Al2O3 substrates was performed by mist chem. vapor deposition. As a source solution, 0.10 mol l-1 of copper (II) acetylacetonate dissolved in 28% aqueous ammonia was used. Even though an aqueous solution was used as the source solution, the epitaxial Cu3N film was realized without the incorporation of CuO and Cu2O phases in the growth of 300°C. The film was also found to have limited O incorporation from the results of scanning transmission electron microscopy and Rutherford back-scattering spectroscopy. The optical property of the Cu3N film was also investigated. The experimental process involved the reaction of Bis(acetylacetone)copper(cas: 13395-16-9Name: Bis(acetylacetone)copper)

《A novel dual mode X-band EPR resonator for rapid in situ microwave heating》 was written by Folli, Andrea; Choi, Heungjae; Barter, Michael; Harari, Jaafar; Richards, Emma; Slocombe, Daniel; Porch, Adrian; Murphy, Damien M.. Recommanded Product: Bis(acetylacetone)copper And the article was included in Journal of Magnetic Resonance in 2020. The article conveys some information:

A unique dual mode X-band Continuous Wave (CW) EPR resonator designed for simultaneous EPR measurement and rapid microwave (MW) induced sample heating is described. Chem. reactions subjected to a flow of energy and matter can be perturbed away from the thermodn. equilibrium by imposing a rapid shock or phys. change to the system. Depending on the magnitude of the perturbation, these changes can dictate the subsequent evolution of the entire system, allowing for instance to populate non-equilibrium reactive intermediate states. Temperature jump (T-jump) experiments are a common method to achieve such perturbations. Most T-jump experiments are based on Joule Heating methods or IR lasers. Here we demonstrate the principle of rapid sample heating based on microwaves. The benefits of MW heating include (i) rapid and efficient heating (i.e. using a tuned resonant cavity, >99% efficient power transfer to the sample can be achieved), and (ii) volumetric heating (i.e. the entire sample volume rises in temperature at once, since heat is generated in the sample instead of being transferred to it). Accordingly, the key concept of the design is the use of a cavity resonator allowing EPR detection (at 9.5 GHz) and simultaneous sample heating (at 6.1 GHz). Temperature increments of 50°C within a few seconds are possible. This is evidenced and illustrated here by probing the temperature-induced variation of the rotational dynamics of 16-doxyl stearic acid Me ester (16-DSE) spin probe grafted on the surface of sodium dodecyl sulfate (SDS) micelles in water, as well as copper (II) acetylacetonate in chloroform. Rapid changes in the rotational dynamics of the paramagnetic centers provide direct evidence for the in situ and simultaneous EPR measurement-heating capabilities of the resonator. Improvements afforded by the use of pulsed MW sources will enable faster heating time scales to be achieved. In the longer term, this current study demonstrates the simple and direct possibilities for using MW heating as a means of performing T-jump experiments After reading the article, we found that the author used Bis(acetylacetone)copper(cas: 13395-16-9Recommanded Product: Bis(acetylacetone)copper)

《Defect-Rich Copper-doped Ruthenium Hollow Nanoparticles for Efficient Hydrogen Evolution Electrocatalysis in Alkaline Electrolyte》 was published in Chemistry – An Asian Journal in 2020. These research results belong to Liang, Jiashun; Zhu, Lixing; Chen, Shaoqing; Priest, Cameron; Liu, Xuan; Wang, Hsing-Lin; Wu, Gang; Li, Qing. Electric Literature of C10H16CuO4 The article mentions the following:

It is of great importance to develop highly efficient and stable Pt-free catalysts for electrochem. hydrogen generation from water electrolysis. Here, monodisperse 7.5 nm copper-doped ruthenium hollow nanoparticles (NPs) with abundant defects and amorphous/crystalline hetero-phases were prepared and employed as efficient hydrogen evolution electrocatalysts in alk. electrolyte. Specifically, these NPs only require a low overpotential of 25 mV to achieve a c.d. of 10 mA cm-2 in 1.0 M KOH and show acceptable stability after 2000 potential cycles, which represents one of the best Ru-based electrocatalysts for hydrogen evolution. Mechanism anal. indicates that Cu incorporation can modify the electronic structure of Ru shell, thereby optimizing the energy barrier for water adsorption and dissociation processes or H adsorption/desorption. Cu doping paired with the defect-rich and highly open hollow structure of the NPs greatly enhances hydrogen evolution activity. In addition to this study using Bis(acetylacetone)copper, there are many other studies that have used Bis(acetylacetone)copper(cas: 13395-16-9Electric Literature of C10H16CuO4) was used in this study.

Facile, low-temperature synthesis of kesterite CZTS nanocrystals (NCs) using single solvent by heating up approach is presented for the first time. Temperature and time dependence on the structural, morphol. and compositional properties are investigated in detail. The size of the NCs was found to increase from 15 to 45 nm with increases in the reaction temperature From the structural anal., secondary and ternary phases were detected at less reaction time, and pure phase of CZTS was obtained at 3 h. On the basis of the detailed time-dependent phase evolution, a plausible formation mechanism of CZTS NCs was proposed. The sequence of CZTS phase evolved from Cu2S phase to Cu2SnS3 intermediate compound and finally to pure kesterite CZTS. The optimal composition of Cu/(Zn + Sn) and Zn/Sn ratio was obtained at 3 h. The calculated band gap was found to be 1.5 eV which is an optimum value for solar cell applications. Thus, the results revealed that the reaction temperature and time played a determining role to obtain pure phase CZTS with controlled composition and optimum band gap.Bis(acetylacetone)copper(cas: 13395-16-9COA of Formula: C10H16CuO4) was used in this study.

In 2019,Chemistry – A European Journal included an article by Chen, Desui; Li, Yifei; Dai, Xingliang; Du, Hui; Lin, Jian; Jin, Yizheng. Electric Literature of C10H16CuO4. The article was titled 《Synthesis of Highly Monodisperse Cu2O Nanocrystals and Their Applications as Hole-Transporting Layers in Solution-Processed Light-Emitting Diodes》. The information in the text is summarized as follows:

The synthesis of phase-pure, narrow-size-distributed and highly stable Cu2O nanocrystals is reported, which can be processed as hole-transporting layers (HTLs) in solution-processed optoelectronic devices. The synthesis is based on a thermal decomposition process with a ligand protection strategy. The reactivity of precursor can be tuned by simply modulating the concentration of oleylamine in non-coordinated solvent, resulting in effectively controlling the size and size distribution of Cu2O nanocrystals. Combined with ligand protection strategy of using lithium stearate and moderate reaction temperature of 170 °C, in situ aggregation of Cu2O nanocrystals could be inhibited, exhibiting excellent stability in hexane for several months. The resulting phase-pure colloidal Cu2O particles (after ozone-treatment) were applied as HTLs in polymer light-emitting diodes, the performance of which are comparable to that of the poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) based devices. In the part of experimental materials, we found many familiar compounds, such as Bis(acetylacetone)copper(cas: 13395-16-9Electric Literature of C10H16CuO4)

The author of the article were Lyu, Mengyao; Lin, Jou; Krupczak, John; Shi, Donglu. The article conveys some information:

A fundamental challenge in energy sustainability is efficient utilization of solar energy towards energy-neutral systems. The current solar cell technologies have been most widely employed to achieve this goal, but are limited to a single-layer 2D surface. To harvest solar light more efficiently, a multilayer system capable of harvesting solar light in a cuboid through transparent photothermal thin films of iron oxide and a porphyrin compound is developed. Analogous to a multilayer capacitor, an array of transparent, spectral selective, photothermal thin films allows white light to penetrate them, not only collecting photon energy in a 3D space, but generating sufficient heat on each layer with significantly increased total surface area. In this fashion, thermal energy is generated via a multilayer photothermal system that functions as an efficient solar collector, energy converter and generator with high energy d. A solar-activated thermal energy generator that can produce heat without any power supply and reach a maximum temperature of 76.1 °C is constructed. With a constant incoming white light (0.4 W cm-2), the thermal energy generated can be amplified 12-fold via multilayers. The multilayer system extends another dimension in solar harvesting and paves a new path to energy generation for the energy-neutral system.

Binary systems based on the Cu, Ni, and Co complexes with various ligands and cationic surfactant cetyltrimethylammonium bromide (CTAB) were prepared The catalytic activity of these systems in the decomposition of tert-Bu hydroperoxide (TBHP) was studied. A specific feature of the CuII-CTAB and NiII-CTAB catalytic systems is that in terms of the decomposition rate of the peroxide bond they are superior to their individual components. The highest efficiency was detected when the copper complexes were used in the binary systems. The CTAB additives combined with Co(acac)2 exert an inhibition effect on the catalytic activity of cobalt, while the CTAB additives exert no effect in the case of other CoL2 compounds Assumptions about the mechanism of action of the binary systems were advanced.

《Effect of acetylacetone metal salts on curing mechanism and thermal stability of polybenzoxazine》 was written by Yan, Hongqiang; Hu, Jianan; Wang, Huaqing; Zhan, Zuomin; Cheng, Jie; Fang, Zhengping. Application In Synthesis of Bis(acetylacetone)copper And the article was included in High Performance Polymers in 2020. The article conveys some information:

To overcome high water absorption of inorganic metal salts and their poor compatibility with resin, acetylacetone metal salts (M(acac)n) were selected as the catalysts of benzoxazine resin. Their effects on the catalytic activity, structure, and thermal stability of polybenzoxazine had been estimated by dynamic differential scanning calorimetry, in situ Fourier transform IR spectroscopy, XPS, and thermal gravimetric analyzer. The results revealed that M(acac)n of iron (Fe3+), cobalt (Co3+ and Co2+), and copper (Cu2+) exhibited high catalytic activity and reduced evidently activation energy, especially acetylacetone iron salt. The addition of M(acac)n was beneficial to the formation of Ph-N-Ph structure, which was easy to form a denser carbon layer during thermal degradation, prevented heat transfer and further decomposition of the resin, and finally led to the increase of carbon residue at high temperature In the experiment, the researchers used many compounds, for example, Bis(acetylacetone)copper(cas: 13395-16-9Application In Synthesis of Bis(acetylacetone)copper)

Reference of Bis(acetylacetone)copper The article mentions the following:

Cu2ZnSnS4 nanocrystals are annealed in a Se-rich atm. inside a transmission electron microscope. During the heating phase, a complete S-Se exchange reaction occurs while the cation sublattice and morphol. of the nanocrystals are preserved. At the annealing temperature, growth of large Cu2ZnSnSe4 grains with increased cation ordering is observed in real-time. This yields an annealing protocol which is transferred to an industrially similar solar cell fabrication process resulting in a 33% increase in the device open circuit voltage. The approach can be applied to improve the performance of any photovoltaic technol. that requires annealing because of the criticality of the process step.
