Adding 1.5 mL DMF to the mixed solution and heating at 60 °C for 12 h to obtain blue CuII-HHTP powder [36]. The resulting products were centrifuged and washed three times in water, ethanol and DMF, alternately. The collected solids were dried at room temperature and saved for further ...
A moulding powder based on urea–formaldehyde will contain a number of ingredients. Those most commonly employed include the following: (1) Resin. (2) Filler. (3) Pigment. (4) Hardener (more commonly referred to as an accelerator). (5) Stabiliser. (6) Plasticiser. (7) Lubricant. The ...
Characters: Appearance: white or slightly yellow ultrafine powder, soluble in water, no odor. Fineness: 90% through 80 mesh sieves. pH:7-8 Main features of the product: 1, feed added about 5% of this product, granulation can produce a strong water resistance,...
While powder flow to roller from feeder, overfeeding may occurs. Overfeeding is harmful because it will cause motor failure. To overcome this problem, the function of roller needs to be improved. The roller will be modified and hence, a new design will be produced.Tan, Chee Fai...
Preparations of Segmented Poly(urethane-urea) with PC Unit (SPUU-2a,b) In the above polymerization reaction, HO-PDMS (2.66 g, 2.66 mmol) was used instead of HO-PTMG, and the similar reactions and reprecipitation were carried out to afford SPUU- 2a as a white powder. Yield: 5.10 g (...
Nevertheless, it is still very challenging to synthesize self-supporting MOF-nanoparticles nanohybrids, which is highly desired for the application in the electrochemical field. On the other hand, OER is a thermodynamically sluggish multi-electron process with large over-potential, leading to energy ...
Aerosol preparations suitable for inhalation may include solutions and solids in powder form, which may be in combination with a pharmaceutically acceptable carrier, such as an inert compressed gas, e.g. nitrogen. Also included are solid form preparations which are intended to be converted, shortly...
in their compound, but any skin bleaching cream with over 2% may cause side effects. The most common side effect of skin bleaching is skin irritation and a burning sensation. The itching or stinging of the skin should be mild and temporary, with some reddening of skin where cream is ...
the counter of the Ni2P/NiF and NiO/NiF catalysts. Finally, we demonstrate that the as-synthesized Ni2P@NiO/NiF catalyst could be a promising electrode for the EOU in urea-rich wastewater and human urine samples for environmental safety management. Overall, the Ni2P@NiO/NiF catalyst electrode...
Experimental Section The expanded graphite-Ag-zeolite-epoxy (EG-Z-Ag-Epoxy) composite electrode was obtained from two-component epoxy resin (LY5052, Araldite) mixed with conductive expanded graphite (EG) fillers powder (Conductograph, SGL Carbon) and silver modified zeolite (clinoptilolite). The ...
