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)

COA of Formula: C10H16CuO4In 2019 ,《Telescoping synthesis and goldilocks of CZTS nanocrystals》 appeared in Materials Research Bulletin. The author of the article were Aruna-Devi, R.; Latha, M.; Velumani, S.; Santoyo-Salazar, J.; Santos-Cruz, J.. The article conveys some information:

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.

《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.

《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)

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)

《Giant Single-Crystal Shape Transformation with Wide Thermal Hysteresis Actuated by Synergistic Motions of Molecular Cations and Anions》 was published in Chemistry – A European Journal in 2020. These research results belong to Wang, Xiao-Lei; Xue, Jin-Peng; Sun, Xiao-Peng; Zhao, Yan-Xin; Wu, Shu-Qi; Yao, Zi-Shuo; Tao, Jun. Safety of Cupric bromide The article mentions the following:

Manipulating the collective mol. movements to implement macroscopic mech. response of bulk material is attractive and challenging. Here, an organic-inorganic hybrid single crystal is synthesized, which exhibits a giant macroscopic shape transformation with a remarkable thermal hysteretic feature. The colossal anisotropic shape change, which manifests as an abrupt elongation of ca. 9 % along the crystallog. c-axis and a concomitant contraction of ca. 9 % in a perpendicular direction, is induced by a significant reorientation of imidazolium, accompanied with a substantial configurational variation in CuBr42- complex anions. The synergistic motions of both the mol. cations and anions engender a remarkable large thermal hysteresis (>30 K) in the shape transformation of the single crystal, implying that this material may play a role in alternating memory media. Furthermore, due to the stable crystal lattice, a single crystal that demonstrates naked-eye detectable large shape transformation was used as a thermal actuator to spontaneously control an elec. circuit by temperature variation.

《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. The experimental part of the paper was very detailed, including the reaction process of Bis(acetylacetone)copper(cas: 13395-16-9Application of 13395-16-9)

Zhao, Wenshi; Yang, Shuo; Guo, Chenzi; Yang, Jinghai; Liu, Yang published an article in 2021. The article was titled 《One-step fabrication of Fe3O4-Cu nanocomposites: High-efficiency and low-cost catalysts for reduction of 4-nitrophenol》, and you may find the article in Materials Chemistry and Physics.COA of Formula: C10H16CuO4 The information in the text is summarized as follows:

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.
