Is CuO Suitable for Improving the Electrochemical Properties of g-C₃N₄?

G-C₃N₄ has a bright application prospect as an electrode material of supercapacitors, which makes it a concern. In order to increase the specific capacitance of g-C₃N₄, we consider to combine it with a metal oxide with high theoretical specific capacitance and utilize the synergistic effect. As a common metal oxide, CuO has the characteristics of high theoretical capacitance, high chemical stability, simple preparation and environmental friendliness.

Liquid Exfoliation and Electrochemical Properties of WS₂ Nanosheets.

Commercial WS2 powders were exfoliated in sodium dodecyl sulfate solution with a combination of ball-milling and sonication. WS2 nanosheets can be uniformly dispersed in the solution. The layers and thicknesses of WS2 nanosheets could be tailored via changing the ball-milling speed.

Effects of micro-magnetic field at the surface of 316L and NiTi alloy on blood compatibility.

We have established the micro-magnetic field on the surfaces of 316L stainless steel and NiTi alloy through the magnetization process of sol-gel prepared TiO(2) thin film with the powder of SrFe(12)O(19). The nano-sized with brown color of SrFe(12)O(19) powder was verified by transmission electron microscope. By using X-ray diffraction, surface roughometer, and corrosion experimental test, the deposited thin film can decrease the etching of body fluid as well as prevent the hazardous Ni ions released from the metal.

[Study on adductive reaction of Ni[(C4H9O)2PS2]2 with nitrogen base by spectrophotometric method(II)].

Reaction of Ni[(C4H9O)2PS2]2 with ethylamine, n-propylamine, n-butylamine, and n-amylamine have been studied by spectrophotometry in ethanol at 30 degrees C. For nitrogen base(B), the adduct formation of NiL2.B and NiL2.
