Spin traps, like 5,5-dimethyl-1-pyrroline N-oxide (DMPO), are commonly used to identify radicals formed in numerous chem. and biol. systems, many of which contain metal-ion complexes. In this study, continuous wave ESR and hyperfine spectroscopy are used to prove the equatorial ligation of DMPO(-derived) mols. to Cu(II), even in the presence of competing nitrogen bases. The exptl. data are corroborated with d. functional theory calculations It is shown that 14N HYSCORE can be used as a fingerprint method to reveal the coordination of DMPO(-derived) mols. to Cu(II), an interaction that might influence the outcome of spin-trapping experiments and consequently the conclusion drawn on the mechanism under study.

《Experimental and Theoretical Study into Interface Structure and Band Alignment of the Cu2Zn1-xCdxSnS4 Heterointerface for Photovoltaic Applications》 was published in ACS Applied Energy Materials in 2020. These research results belong to Rondiya, Sachin R.; Jadhav, Yogesh; Dzade, Nelson Y.; Ahammed, Raihan; Goswami, Tanmay; De Sarkar, Abir; Jadkar, Sandesh; Haram, Santosh; Ghosh, Hirendra N.. COA of Formula: C10H16CuO4 The article mentions the following:

To improve the constraints of kesterite Cu2ZnSnS4 (CZTS) solar cell, such as undesirable band alignment at p-n interfaces, bandgap tuning, and fast carrier recombination, cadmium (Cd) is introduced into CZTS nanocrystals forming Cu2Zn1-xCdxSnS4 through cost-effective solution-based method without postannealing or sulfurization treatments. A synergetic exptl.-theor. approach was employed to characterize and assess the optoelectronic properties of Cu2Zn1-xCdxSnS4 materials. Tunable direct band gap energy ranging from 1.51-1.03 eV with high absorption coefficient was demonstrated for the Cu2Zn1-xCdxSnS4 nanocrystals with changing Zn/Cd ratio. Such bandgap engineering in Cu2Zn1-xCdxSnS4 helps in effective carrier separation at interface. Ultrafast spectroscopy reveals a longer lifetime and efficient separation of photoexcited charge carriers in Cu2CdSnS4 (CCTS) nanocrystals compared to that of CZTS. It was found that there exists a type-II staggered band alignment at the CZTS (CCTS)/CdS interface, from cyclic voltammetric (CV) measurements, corroborated by first-principles d. functional theory (DFT) calculations, predicting smaller conduction band offset (CBO) at the CCTS/CdS interface as compared to the CZTS/CdS interface. These results point toward efficient separation of photoexcited carriers across the p-n junction in the ultrafast time scale and highlight a route to improve device performances. The experimental part of the paper was very detailed, including the reaction process of Bis(acetylacetone)copper(cas: 13395-16-9COA of Formula: C10H16CuO4)

In 2022,Kim, Jaewon; Kendall, Owen; Ren, Jiawen; Murdoch, Billy J.; McConville, Christopher F.; van Embden, Joel; Della Gaspera, Enrico published an article in ACS Applied Materials & Interfaces. The title of the article was 《Highly Conductive and Visibly Transparent p-Type CuCrO2 Films by Ultrasonic Spray Pyrolysis》.Application of 13395-16-9 The author mentioned the following in the article:

The development of high-performing p-type transparent conducting oxides will enable immense progress in the fabrication of optoelectronic devices including invisible electronics and all-oxide power electronics. While n-type transparent electrodes have already reached widespread industrial production, the lack of p-type counterparts with comparable transparency and conductivity has created a bottleneck for the development of next-generation optoelectronic devices. In this work, we present the fabrication of delafossite copper chromium oxide p-type transparent electrodes with outstanding optical and elec. properties. These layers were deposited using ultrasonic spray pyrolysis, a wet chem. method that is fast, simple, and scalable. Through careful screening of the deposition conditions, highly crystalline, dense, and smooth CuCrO2 coatings were obtained. A detailed investigation of the role played by the deposition temperature and the cation ratio enabled the properties of the prepared layers to be reliably tuned, as verified using X-ray diffraction, XPS, optical spectroscopy, Hall effect measurements, and electron and at. force microscopies. We demonstrate record conductivities for solution-processed CuCrO2, exceeding 100 S cm-1, and we also obtained the highest value for two sep. figures of merit for p-type transparent conducting oxides. These performances position solution-deposited CuCrO2 as the leading p-type transparent-conducting oxide currently available.

The article was titled 《Growth-Temperature Dependent Unpassivated Oxygen Bonds Determine the Gas Sensing Abilities of Chemical Vapor Deposition-Grown CuO Thin Films》, and you may find the article in ACS Applied Materials & Interfaces.Application of 13395-16-9 The information in the text is summarized as follows:

CuO is a multifunctional metal oxide excellent for chemiresistive gas sensors. In this work, we report CuO-based NO2 sensors fabricated via chem. vapor deposition (CVD). CVD allows great control on composition, stoichiometry, impurity, roughness, and grain size of films. This endows sensors with high selectivity, responsivity, sensitivity, and repeatability, low hysteresis, and quick recovery. All these are achieved without the need of expensive and unscalable nanostructures, or heterojunctions, with a technol. mature CVD. Films deposited at very low temperatures (≤350°C) are sensitive but slow due to traps and small grains. Films deposited at high temperatures (≥550°C) are not hysteretic but suffer from low sensitivity and slow response due to lack of surface states. Films deposited at optimum temperatures (350-450°C) combine the best aspects of both regimes to yield NO2 sensors with a response of 300% at 5 ppm, sensitivity limit of 300 ppb, hysteresis of <20%, repeatable performance, and recovery time of ~1 min. The work demonstrates that CVD might be a more effective way to deposit oxide films for gas sensors.

In 2022,Pushpalatha, Nataraj; Abraham, Elezabeth V.; Saravanan, Govindachetty published an article in New Journal of Chemistry. The title of the article was 《Pt-Cu nanoalloy catalysts: compositional dependence and selectivity for direct electrochemical oxidation of formic acid》.Computed Properties of C10H16CuO4 The author mentioned the following in the article:

Tuning catalytic activity without increasing the platinum (Pt) load in electrode catalysts is one of the essential steps to realizing a viable fuel cell technol. on a larger scale. The formation of a Pt-alloy phase with various compositions may enhance the catalytic activity without increasing the Pt load. In this work, we report the compositional dependence of Pt-Cu nanoalloy catalysts for direct formic acid (FA) oxidation without changing the Pt load. Pt-Cu nanoalloy catalysts with various compositions (Pt : Cu = 3 : 1, 1 : 1 and 1 : 3) were prepared by a thermal reduction method using stoichiometric amounts of Pt and Cu precursors at various set temperatures (500 and 800°C), where the Pt loading (5 wt%) was maintained the same for all the tested catalytic compositions The formation of the Pt-Cu alloy phase was confirmed by pXRD as the characteristic diffraction peaks were shifted to higher diffraction angles when compared with those of the pure phase of Pt. The average particle sizes of Pt3Cu, PtCu and PtCu3 are 5, 3, and 20 nm, resp. Although of larger particle size and lower electrochem. surface area than com. Pt and the other Pt3Cu and PtCu catalysts, the PtCu3 nanoalloy catalyst showed a much-improved direct FA oxidation performance both in terms of mass and specific catalytic activity when compared with the other catalysts, implying the intrinsic catalytic activity of the PtCu3 nanoalloy phase. The Pt-Cu nanoalloy catalysts showed selectivity for the direct electrochem. oxidation of FA over other fuels (e.g., methanol and ethanol). Although the multi-cycle performance of all the Pt-Cu nanoalloy catalysts decreased with the increase of the number of cycles, the catalytic performance of the PtCu3 nanoalloy catalyst was still higher in the tested 1000 cycles when compared with that of the other Pt3Cu and PtCu nanoalloy catalysts and the com. Pt catalyst. In the experiment, the researchers used many compounds, for example, Bis(acetylacetone)copper(cas: 13395-16-9Computed Properties of C10H16CuO4)

In 2022,Mosaferi, M.; Selles, P.; Miteva, T.; Ferte, A.; Carniato, S. published an article in Journal of Physical Chemistry A. The title of the article was 《Interpretation of Shakeup Mechanisms in Copper L-Shell Photoelectron Spectra》.Recommanded Product: Bis(acetylacetone)copper The author mentioned the following in the article:

We report on an original full ab initio quantum mol. approach designed to simulate Cu 2p X-ray photoelectron spectra. The description includes electronic relaxation/correlation and spin-orbit coupling effects and is implemented within nonorthogonal sets of MOs for the initial and final states. The underlying mechanism structuring the Cu 2p photoelectron spectra is clarified thanks to a correlation diagram applied to the CuO4C6H6 paradigm. This diagram illustrates how the energy drop of the Cu 3d levels following the creation of the Cu 2p core hole switches the nature of the highest singly occupied MO (H-SOMO) from dominant metal to dominant ligand character. It also reveals how the repositioning of the Cu 3d levels induces the formation of new bonding and antibonding orbitals from which shakeup mechanisms toward the relaxed H-SOMO operate. The specific nature, ligand → ligand and metal → ligand, of these excitations building the satellite lines is exposed. Our approach finally applied to the real Cu(acac)2 system clearly demonstrates how a definite interpretation of the XPS spectra can be obtained when a correct evaluation of binding energies, intensities, and relative widths of the spectral lines is achieved.

The article was titled 《Surface Coordination Layer to Enhance the Stability of Plasmonic Cu Nanoparticles》, and you may find the article in Journal of Physical Chemistry C.Formula: C10H16CuO4 The information in the text is summarized as follows:

The fast oxidation of plasmonic Cu nanomaterials caused by surface-absorbed oxygen has been a serious problem and has hindered their applications in many aspects. Herein, a lollipop-shaped Cu@Cu2O/ZnO heterojunction with a core-shell head and a rodlike stem was successfully prepared using the colloidal chem. method, which exhibits ultralong-term stability against air oxidation in hexane. The enhanced stability of Cu@Cu2O/ZnO was due to the presence of zinc acetate, which resulted in the crystal face reconstruction of Cu@Cu2O and the formation of a thin surface carboxylate coordination layer on the partial surface of Cu@Cu2O. The passivation layer effectively hindered the absorption of surface oxygen, thus reducing the oxidation rate of Cu. Our current work was expected to provide new insights into the protection of active metal nanostructures.

The article was titled 《Enhanced photocatalytic hydrogen production activity of Janus Cu1.94S-ZnS spherical nanoheterostructures》.HPLC of Formula: 13395-16-9 The article contains the following contents:

Photocatalytic hydrogen evolution is one of the most promising approaches for efficient solar energy conversion. The light-harvesting ability and interfacial structure of heterostructured catalysts regulate the processes of photon injection and transfer, which further determines their photocatalytic performances. Here, we report a Janus Cu1.94S-ZnS nano-heterostructured photocatalyst synthesized using a facile stoichiometrically limited cation exchange reaction. Djurleite Cu1.94S and wurtzite ZnS share the anion skeleton, and the lattice mismatch between immiscible domains is ∼1.7%. Attributing to the high-quality interfacial structure, Janus Cu1.94S-ZnS nanoheterostructures (NHs) show an enhanced photocatalytic hydrogen evolution rate of up to 0.918 mmol h-1 g-1 under full-spectrum irradiation, which is ∼38-fold and 17-fold more than those of sole Cu1.94S and ZnS nanocrystals (NCs), resp. The results indicate that cation exchange reaction is an efficient approach to construct well-ordered interfaces in hybrid photocatalysts, and it also demonstrates that reducing lattice mismatch and interfacial defects in hybrid photocatalysts is essential for enhancing their solar energy conversion performance.

COA of Formula: C10H16CuO4 And the article was included in ACS Sustainable Chemistry & Engineering in 2020. The article conveys some information:

In recent years, metal isolated site catalysts with the high exposure and maximized availability of metal species provide a new route to boost the oxygen reduction performance. However, in the absence of clusters and nanoparticles, the synthesis of this catalyst with metal high-loading, especially for copper, is still a big challenge. In this work, a metal isolated site catalyst with high copper content (1.12 wt %), copper isolated sites anchored on N-doped carbon materials (donated as Cu ISs/NC-1000), was prepared by the pyrolysis of copper acetylacetone within the metal-organic framework (ZIF-8) at 1000°C. The successful preparation of products can be demonstrated by high-angle annular dark-field scanning transmission electron microscopy and X-ray absorption spectra. With the merits of the atomically dispersed surface metal atoms and abundant ORR-favored copper active sites, the present Cu ISs/NC-1000 exhibits an excellent ORR electrochem. activity with a half-wave potential of 0.855 V (vs RHE) and a limiting c.d. of 5.2 mA cm-2 in the electrochem. tests, superior to the results from com. Pt/C and previously reported Cu-based materials. For the durability, the negligible activity decay after 10,000 continuous potential cycles and good resistance to methanol crossover can be noted. The outstanding catalytic activity from the present Cu ISs/NC-1000 demonstrates the superiority of metal isolated sites as electrocatalytic centers. The excellent ORR activity of Cu ISs/NC catalysts in this work promotes the development of clean and sustainable energy devices.
