Calam, Tugba Tabanligil published the artcileElectrochemical Oxidative Determination and Electrochemical Behavior of 4-nitrophenol Based on an Au Electrode Modified with Electro-polymerized 3,5-diamino-1,2,4-triazole Film, Product Details of C2H5N5, the main research area is nitrophenol analysis water gold electrode diaminotriazole film.

A simple and fast electrochem. method was described and evaluated to determine the hazardous compound, 4-nitrophenol (4NP). In this work, concentration of 4NP was determined by differential wave voltammetry (DPV). A gold electrode (Au) was modified with 3,5-diamino-1,2,4-triazole (35DT). The modified electrode (35DT-Au) was characterized by using electrochem. impedance spectroscopy (EIS), fourier transform IR spectrophotometry (FTIR), cyclic voltammetry (CV) and DPV. The modified electrode showed more sensitivity towards 4NP compared to unmodified one. A wide linear concentration range from 0.24 to 130.6μM was obtained for 4NP with a detection limit of 0.09μM. In the reproducibility and repeatability studies, the relative standard deviation (RSD%) values of the method were obtained as 3.72% and 2.56%, resp., which are acceptable values. This proposed method was successfully used for the anal. of 4NP in lake and tap water samples. Simplicity, sensitivity, selectivity and high efficiency of the proposed method can be used in routine anal. of trace amounts of 4NP in polluted waters.

Chen, Xinyi published the artcileControlling Speciation during CO2 Reduction on Cu-Alloy Electrodes, Recommanded Product: 3,5-Diamino-1,2,4-triazole, the main research area is carbon dioxide reduction copper alloy ethylene Raman cupric oxide.

Electrodeposition of Cu, Cu/Ag, and Cu/Sn alloy films by using 3,5-diamino-1,2,4-triazole (DAT) as an electrodeposition inhibitor yields a high surface area Cu-based catalyst. All three Cu-based electrodes exhibit high Faradaic efficiency (FE) of CO2 reduction toward C2H4 production The CuSn-DAT electrode exhibits the highest FE for CO (∼90% at -0.4 V) and C2H4 (∼60% at -0.8 V) production and high c.d. (∼-225 mA/cm2 at -0.8 V). In situ surface enhanced Raman spectroscopy (SERS) studies in a flow cell obtained from the three Cu-based samples show a correlation between the decreased oxide content on the Cu surface, increased presence of CO, and increased activity for CO and C2 production The CuSn-DAT electrode has the lowest amount of Cu2O and exhibits the highest activity, whereas the Cu-DAT electrode has an increasing Cu2O content and exhibits lower activity as the potential is made neg. These results demonstrate that incorporation of different well-mixed alloy materials provides a way to tune CO2 reduction speciation.

Jeong, Mi Ho published the artcilePre-validation of a Calu-3 epithelium cytotoxicity assay for predicting acute inhalation toxicity of chemicals, SDS of cas: 598-50-5, the main research area is Inhalation toxicity cyclohexanol pentanal; Acute inhalation toxicity; Alternative test; Calu-3 epithelium; Cytotoxicity assay; Pre-validation study.

Although in vivo inhalation toxicity tests have been widely conducted, the testing of many chems. is limited for economic and ethical reasons. Therefore, we previously developed an in vitro acute inhalation toxicity test method. The goal of the present pre-validation study was to evaluate the transferability, reproducibility, and predictive capacity of this method. After confirming the transferability of the Calu-3 epithelium cytotoxicity assay, reproducibility was evaluated using 20 test substances at three independent institutions. Cytotoxicity data were analyzed using statistical methods, including the intra-class correlation coefficient and Bland-Altman plots for within- and between-laboratory reproducibility. The assay for the 20 test substances showed excellent agreement within and between laboratories To evaluate the predictive capacity, 77 test substances were analyzed for acute inhalation toxicity. Accuracy was measured using a cutoff of 40%, and the relevance was analyzed as a receiver-operating characteristic (ROC) curve. An accuracy of 72.73% was obtained, and the area under the ROC curve was 0.77, indicating moderate performance. In this study, we found that the in vitro acute inhalation toxicity test method demonstrated good reliability and relevance for predicting the acute toxicity of inhalable chems. Hence, this assay has potential as an alternative test for screening acutely toxic inhalants.

Fonseca, Sarah published the artcileOxygen Reduction Reaction on a CuII Complex of 3,5-Diamino-1,2,4-triazole: A DFT Approach, Recommanded Product: 3,5-Diamino-1,2,4-triazole, the main research area is oxygen reduction reaction diaminotriazole copper complex electrocatalyst analysis.

The high costs for producing catalysts for fuel cells combined with low efficiency in oxygen reduction make metal-organic complexes a promising alternative to noble-metal catalysts. The electrochem. activity of Cu-complex-based catalysts has been reported by many authors, but only a few works are devoted to theor. studies. In this manuscript, d. functional theory (DFT) calculations are used to investigate the oxygen reduction reaction (ORR) on a CuII complex of 3,5-diamino-1,2,4-triazole. The determining steps for the associative and dissociative mechanisms are the oxygen adsorption and the oxygen bond cleavage, resp. The barrier for breaking the O-O bond in the dissociative mechanism was estimated at 0.7 eV.

Jiang, Jingyun published the artcilePoly-quasi-eutectic solvents (PQESs): versatile solvents for dissolving metal oxides, Related Products of isoquinoline, the main research area is polyquasieutectic solvent polymer hydrogen bond donor dissolution metal oxide; carboxylic acid mixture polymer polyquasieutectic solvent dissolution metal oxide; amide mixture polymer polyquasieutectic solvent dissolution metal oxide.

The concept of poly-quasi-eutectic solvents (PQESs) has been proposed in this study. A class of PQESs composed of polymers, namely polyethylene glycol (PEG), poly(ethylene glycol)-block-poly(propylene glycol)-block poly(ethylene glycol) (P123), poly(propylene glycol) bis(2-aminopropyl ether) (PPG-NH2), and poly(ethylene glycol) di-Me ether (DMPEG), and hydrogen bonding donors (HBDs, including carboxylic acids and amides) were prepared, which could be used for dissolving metal oxides. The PQESs were formed by simply mixing the selected polymers and HBDs. The PEG-based PQESs have excellent physiochem. properties, including negligible volatility, low viscosity, intrinsic conductivity, and wide electrochem. windows. Moreover, they were shown to be good solvents for metal oxides, which have potential applications in industrial metallurgical processes.
