Features and Benefits

Methylsilane is used in the plasma-assisted CVD of silicon carbide (SiC) and as a precursor to the epitaxial growth of SiGeC alloy layers via rapid thermal CVD. Recent developments include the use of methylsilane as a precursor to silicon-carbon-hydrogen polymer used as photoresists.
Precursor to silicon carbide or alloy thin films by chemical vapor deposition (CVD) and molecular beam epitaxy (MBE).

Interface conditions are an important property that can affect the drag of fluid flow. For surfaces with different oleophobicity, the boundary slip at the solid-oil interface is mostly larger than that at the solid-water interface. Roughness is a key factor

How to balance the sensitivity and signal-to-noise ratio of immunosensor remains many challenges during various diseases diagnosis. Here we develop a new microfluidic immunosensor based on surface-modified mesoporous nanofibers, and simultaneously realize an ultra-sensitivity and high signal-to-noise ratio for the
