In 2016,Farzaneh, Amir; Hosseini, Mir Ghasem; Asl, Shahin Khameneh; Mermer, Omer published 《Electrochemical, structural and nano tribological behavior of Ni-W-PTFE nanocomposite coatings prepared by tartrate bath》.International Journal of Electrochemical Science published the findings.SDS of cas: 6381-59-5 The information in the text is summarized as follows:

A tartrate nickel plating bath has been used to prepare nickel- tungsten (Ni-W) dispersed PTFE composite coatings with four different PTFE contents (0, 4, 8 and 20 gl-1). The coatings are characterized using of Field-Emission SEM (SEM), Energy Dispersive Xray Anal. (EDAX) and X-ray Diffractrometry (XRD). XRD results indicate that the PTFE particle changed the surface texture significantly. The nano tribol. behavior of the nano composite coating was estimated by contact mode of AFM. Electrochem. performance of the nanocomposite depositions was evaluated using potentiodynamic polarization and electrochem. impedance spectroscopy (EIS). The results show that the Ni-W/PTFE nanocomposite films exhibit better electrochem. and tribol. performance than the Ni-W coating. The corrosion rate and surface roughness decreased about 50 and 5 times less than bare coating in optimum condition 8 gl-1 PTFE.

In 2019,Transition Metal Chemistry (Dordrecht, Netherlands) included an article by Qin, Yutian; Wang, Bowei; Li, Jiayi; Wu, Xingchun; Chen, Ligong. Quality Control of 2,6-Pyridinedimethanol. The article was titled 《Cobalt imine-pyridine-carbonyl complex functionalized metal-organic frameworks as catalysts for alkene epoxidation》. The information in the text is summarized as follows:

Aerobic epoxidation of alkene is a green and economical route to produce epoxides. For such reaction, transition metal complexes exhibit favorable catalytic activity. In this work, NH2-MIL-101, a stable metal-organic framework (MOF) material with large surface area and high pore volume, was functionalized with pyridine-2,6-dicarbaldehyde and Co(NO3)2, to realize the immobilization of Co(II) via imine-pyridine-carbonyl (N,N,O) tridentate ligands bonding to MOF skeleton. The modified materials were applied as heterogeneous catalysts for the aerobic epoxidation of cyclohexene at ambient temperature, and multiple factors were studied to explore their influences on catalytic effects. Under the optimal reaction conditions, satisfactory substrate conversion and epoxide selectivity were reached. In addition, this catalytic system is suitable for a variety of alkene substrates. Furthermore, recycle experiments and IR spectroscopy characterization illustrated that the coordination surroundings of Co are altering smoothly during the reaction process, thus having an impact on the performance of catalyst.

An environmentally benign protocol for diversity-oriented synthesis of functionalized bioactive dihydropyrano[2,3-c]pyrazole and benzylpyrazolyl coumarin derivatives has been investigated by the reaction of aryl aldehydes, Et acetoacetate, hydrazine derivatives, malononitrile and 4-hydroxycoumarin in the presence of melamine-modified chitosan (Cs-Pr-Me) materials as a reusable bifunctional organocatalyst.
