Integration of ultrafine CuO nanoparticles with two-dimensional MOFs for enhanced electrochemical CO₂ reduction to ethylene was written by Wang, Linlin;Li, Xin;Hao, Leiduan;Hong, Song;Robertson, Alex W.;Sun, Zhenyu. And the article was included in Chinese Journal of Catalysis in 2022.Recommanded Product: Cuprichydroxide This article mentions the following:

To facilitate the electrochem. CO₂ reduction (ECR) to fuels and valuable chems., the development of active, low cost, and selective catalysts is crucial. We report a novel ECR catalyst consisting of CuO nanoparticles with sizes ranging from 1.4 to 3.3 nm anchored on Cu metal-organic framework (Cu-MOF) nanosheets obtained through a one-step facile solvothermal method. The nanocomposites provide multiple sites for efficient ambient ECR, delivering an average C₂H₄ faradaic efficiency (FE) of ∼50.0% at -1.1 V (referred to the reversible hydrogen electrode) in 0.1 mol/L aqueous KHCO3 using a two-compartment cell, in stark contrast to a C₂H₄ FE of 25.5% and 37.6% over individual CuO and Cu-MOF resp., also surpassing most newly reported Cu-based materials under similar cathodic voltages. The C₂H₄ FE remains at over 45.0% even after 10.0 h of successive polarization. Also, a ∼7.0 mA cm^-2 C₂H₄ partial geometric c.d. and 27.7% half-cell C₂H₄ power conversion efficiency are achieved. The good electrocatalytic performance can be attributed to the interface between CuO and Cu-MOF, with accessible metallic moieties and the unique two-dimensional structure of the Cu-MOF enhancing the adsorption and activation of CO₂ mols. This finding offers a simple avenue to upgrading CO₂ to value-added hydrocarbons by rational design of MOF-based composites. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Recommanded Product: Cuprichydroxide).

In vitro pesticides susceptibility of Erwinia sp. causing papaya (Carica papaya) black rot in Okinawa, Japan and captan effectiveness on papaya pot seedlings was written by Hanagasaki, Takashi;Takushi, Tetsuya;Kawano, Shinji;Yamashiro, Maki. And the article was included in Journal of General Plant Pathology in 2022.Formula: CuH2O2 This article mentions the following:

Since 2002, papaya black rot has been spreading over several islands of Okinawa Prefecture. The pathogen of the disease was identified as Erwinia sp., genetically close to E. mallotivora and E. papayae. In terms of the disease transmission, it is probably carried by the wind or rain. In order to devise a prevention strategy for the disease, in vitro pesticides susceptibility of the pathogen and tests with papaya pot seedlings were conducted. A min. inhibitory concentration assay demonstrated that copper (II) hydroxide, basic copper sulfate, and captan present in the papaya-registered pesticides inhibited the growth of the pathogen on nutrient agar plates. In addition, mancozeb that is non-papaya-registered pesticide also showed an inhibitory effect on the pathogen. Thus, there is a high possibility that even the existing papaya-registered or non-papaya-registered pesticides can prevent papaya black rot. In the test with papaya pot seedlings, copper (II) hydroxide exerted a relatively lower pesticide effect; however, captan exhibited a pesticide effect, although it is one of the fungicides not registered for use in the treatment of bacterial diseases of plants in Japan till date. Indeed, based on the result of the present study, the official registration of legal expansion for use of captan to control papaya black rot was approved in Japan on Dec. 22, 2021. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Formula: CuH2O2).

Metallic coloration and multifunctional preparation on fabrics via nitriding reactive sputtering with copper and titanium targets was written by Huang, Mei-Lin;Wu, Ying-Zhu;Liu, Zhi-Kai;Lu, Sheng-Guo. And the article was included in Vacuum in 2022.Application In Synthesis of Cuprichydroxide This article mentions the following:

Metallic coloration and multiple functions were prepared on polyester woven fabrics via nitriding reactive magnetron sputtering with copper and titanium targets. The resulting colors ranged from light gray to pale yellow. The color of the copper film-coated fabrics was affected by elemental Cu, Cu₂O, and Cu(OH)₂ in the films. These species had a bandgap of 2.16 eV and a corresponding absorption edge of 574 nm. The color of the titanium film-coated fabrics was tuned via TiO₂ and TiON with a bandgap of 2.35 eV and a corresponding absorption edge of 528 nm. The films’ color brightness and the optical bandgap decreased with a red shift in the absorption edge for the absorption of visible light. This phenomenon increased as the film thickness increased with increasing sputtering current. The UV protection performance of the copper film-coated fabrics was significantly and rapidly improved by increasing the sputtering current. An average UPF of 234.1 and an average improvement of 287.3% were obtained for the CuN series samples. The elimination of static electricity was improved for the two series of coated fabrics. This research offers a reference for structural coloration or metallic coloration on textiles and the preparation of functional textiles.

Wastewater containing oil and surfactant pollution causes health, environment, and resource issues. Surfactant-stabilized emulsion separation is conventionally achieved by modified sponges, membranes and micro-nanoparticles, still, with relevant limitations in low durability, high energy consumption, and discontinuity. Inspired by nasal cavity, a superhydrophobic/superoleophilic nanowires decorated cone array tube with penetrated pores is demonstrated for oil recovery in micron-sized oil-in-water emulsions. The exptl. results reveal that the separation efficiency can reach 99.84% and the oil recovery efficiency can achieve 92% at the same time. Oil droplets are captured by cones under the synergy of superwettability and gradient structure, and then transport driven by the force of Laplace pressure. The whole process of oil recovery in wastewater is continuous, durable, and versatile for different oil/surfactant contents.

Electrochem. reduction of CO₂ to multi-carbon fuels and chem. feedstocks is an appealing approach to mitigate excessive CO₂ emissions. However, the reported catalysts always show either a low Faradaic efficiency of the C₂₊ product or poor long-term stability.

And the article was included in Separation and Purification Technology in 2022.Electric Literature of CuH2O2 This article mentions the following:

Development of an under-liquid super-repellent (ULSR) surface that can act as a versatile platform for separating both liquid/liquid and liquid/gas mixtures is highly desirable, yet still hard to realize. Herein, to address this challenge, a Cu(OH)₂ nanowire textured surface on copper mesh was developed through a simple immersion process. The resulting Cu(OH)₂ nanowire surface displayed underwater superoleophobicity, underoil superhydrophobicity, and unusual dual superoleophobicity under immiscible oil-oil system. Exploiting its superlyophobicity under-liquid, the Cu(OH)₂ nanowire covered copper mesh was applied to sep. oil/water mixtures, emulsions, and oil/oil mixtures effectively, even though the surface tension between two liquids was just 2.4 mN/m. The separation efficiency is higher than 99% for all mixtures, and the oil/water separation efficiency can maintain above 98% even after 40 cycles. Furthermore, owing to its superaerophobicity underwater and underoil, the obtained copper mesh was also able to sep. gas from bulk water and oil efficiently. This work is hoped to provide a key addition to the fields of ULSR surfaces as well as membrane-based separation techniques.

High-performance semiconductor gas sensors comprising of metal oxides have offered appealing promise to environment monitor devices but remain challenging due to their high working temperature and sluggish response/recovery speed. Here we report a simple impregnation method that utilizing the high catalytic activity of palladium oxide activates copper oxide parallel nanowires assembled hierarchical microspheres (PdO-CuO NWMs). And then gas-sensing devices with different decorating concentrations were fabricated to investigate their sensing performance on hydrogen sulfide (H₂S). It was demonstrated that the CuO microspheres with 2 wt% PdO decorating concentration is the optimum, with high response of 6.8 and extremely short response/recovery time of 1.8/4.1 s towards 50 ppm H₂S at 30°C, effective enhancing the response (4.9-50 ppm H₂S) and working temperature (150°C) of pristine CuO NWMs sensor. The boosting sensing performance of our PdO-CuO NWMs gas sensor was attributed to the synergistic effect of high catalytic noble nanoparticles and hierarchical structures. The coupling strategy offers new insights to explore room temperature and real-time monitoring gas sensors.

Improving the cycling stability of lithium metal anodes using Cu₃N-modified Cu foil as a current collector was written by Tang, Danlei;Yuan, Lixia;Liao, Yaqi;Jin, Wenxuan;Chen, Jie;Cheng, Zexiao;Li, Xiang;He, Bin;Li, Zhen;Huang, Yunhui. And the article was included in Science China Materials in 2022.COA of Formula: CuH2O2 This article mentions the following:

Lithium (Li) metal anodes have the potential to stimulate the development of secondary batteries due to their high theor. specific capacities and low redox potentials among all possible solid secondary anode compounds However, the growth of Li dendrites during repeated Li stripping/plating processes leads to low coulombic efficiencies (CEs) and safety hazards, which significantly hinders their practical application. In this work, com. Cu foil was modified in situ by Cu₃N nanowires (Cu₃N NWs/Cu) and used as the current collector for a Li anode. In addition to decreasing the true c.d. of the anode and alleviating the volume change during the cycles, Cu₃N reacted with Li during the initial cycle (3Li + Cu₃N → Li3N + 3Cu), which enabled the formation of a Li3N-rich solid electrolyte interphase (SEI). This Li3N-rich SEI with a high ionic conductivity not only boosted Li ion transport but also promoted the homogeneous deposition of Li via increased Li nucleation sites. The improvements in both mass transport and deposition dynamics restrained dendrite growth. As a result, the Cu₃N NWs/Cu anode had stable Li plating/stripping over 270 cycles with a high average CE of 98.6% at 1 mA cm^-2, with Li capacities of 1 mA h cm^-2. A long cycling lifespan of 430 cycles was achieved using a full cell with a high-load LiFePO₄ cathode (mass loading: 10 mg cm^-2) and a Cu3N NWs/Cu-Li anode (N/P = 2.35), demonstrating the effectiveness and practicality of the Cu₃N NWs/Cu current collector in stabilizing the Li anode.

N.;Lin, Jui-Yen;Shih, Yu-Jen;Huang, Yao-Hui. And the article was included in Journal of Environmental Chemical Engineering in 2022.Formula: CuH2O2 This article mentions the following:

The fluidized-bed crystallization (FBC) removes heavy metals onto the fluidized pellets, which is an outstanding alternative to the precipitation method. This study simultaneously recovers iron and copper as binary metal-oxide pellets (Fe^III_0.66Cu^I_0.33 @SiO₂) in a synthetic wastewater using FBC and silica as a seed material. The operating parameters for FBC include the Fe/Cu ratio, pH, cross-sectional loading (L, kg/m².h) and bed height (H, cm) and these are optimized to maximize the crystallization efficiency of iron and copper. At pH = 8, an input Fe/Cu ratio = 2 at a total metal concentration of 3 mM, the crystallization ratio (CR) and the total resp. metal removal (TR) for Fe and Cu is 90% and 99%. Precipitation rates of 0.88 and 0.38 mg-metal/ gr-seed•h were obtained at resp. cross-sectional loadings of 0.25 kg m^-2•h and 0.15 kg m^-2•h for Fe and Cu. The crystal phases of FBC product are resp. characterized as FeOOH and Cu₂O by XRD anal. The high crystallization ratio and the recovery of crystal pellet product indicated that the quantity of the sludge has been reduced significantly in comparison to the traditional chem. precipitation In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Formula: CuH2O2).
