We have developed a laser-induced chemical vapor deposition (LCVD) method for preparing nanocarbons with the aid of SF 6 . This method would offer advantages for the production of aggregates of nanoscale foams (nanofoams) at high rates. Pyrolysis of

Power devices play an important role in energy saving and material substrates for power devices such as sapphire, silicon carbide (SiC), gallium nitride (GaN), and diamond are attracting extensive concern. However, because of the high hardness and st

We derive a means to construct a locally supported basis for the truly bivariate cardinal spline functions under the influence of parameter called tension being a different constant in each grid cell. First, the functions are formulated as a solution

The structure of single-wall carbon nanohorn (SWNH) was analyzed with X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy. The considerably strong peak due to single bonding carbons was observed in C1s XPS spectrum of SWNH. This peak intens

Reduction of debris adhesion and increasing the process performance by SF6 assist laser processing of silicon wafer was investigated. It is observed that debris adhesion was drastically reduced when SF6 gas was used to compare the case of He gas. Sha

An extension of the bivariate cubic spline on the uniform grid is derived in this paper to have different tensions in different square cells of the grid. The resulting function can be interpreted also as a bivariate extension of the univariate spline
