and mechanical properties and polishability were investigated. 2 Fabrication of basic samples Carbon and SiC particles were mixed with distilled water and dispersant to a colloidal suspension. The suspension... increases slowly below 500℃ in order to remove organic dispersant. Above 1 410 ℃, molting silicon began to infiltrate into the green body and reacted with free carbon to form new SiC phase replacing......
by electroplating metal nickel on a carbon fiber. CHOU et al[5] invented a method for synthesizing nickel fibers with a diameter ranging from submicron to microns and a length up to centimeters. The invention... two gel precursors. 4) At 380-500℃ and over, the mass loss decreases substantially. It is believed that this decomposition stage comprised of further oxidation of the residual carbon and formation......
) By hydrogen thermal treatment at 600 ℃ for 2 h the elementary composition of nickel particles before and after the hydrogen thermal treatment. There contain carbon and oxygen elements in the as-prepared nickel powders, but there is no carbon or oxygen element after the hydrogen deoxidation. 4 Conclusions 1) Ultrafine core-shell nickel spheres are fabricated via a simple chemical method using self......

for the production of silver nanoparticle by using nano-carbon as active template. Special ultrasonic condition was used to assure the active effect of the template and achieve an even and stable micro-reactor... with the standard JCPDS card of silver. The results reveal that the nano-carbon in active template system not only exerts micro-reactor and steric stabilization effect, but also acts as reducing agent during......
with relatively inexpensive reagents and have high stability constant values of the metal complexes formed. Xanthates are formed by reacting an organic hydroxyl-containing substrate with carbon disulfide... was stirred at room temperature (25 ℃) for 3 h and for another 3 h after addition of 10 mL carbon disulphide (CS2). This mixture was then allowed to settle for 1 h. After that, the supernatant......
is described as follows: approximately 5 g of asphalt sample after RTFO was diluted by carbon disulfide to form a mixture of 15 g to 25 g. The mixture was deposited onto a glass plate that was placed... amplitude was 56 mW. A thermo Nicolet Model Nexus FTIR-Raman spectrophotometer loaded with Omnic 6.2 software was used to acquire FTIR spectra by weight solutions of asphalt prepared in carbon......
