Creating microfluidic channels functionalized with micro- and nano-scale features via femtosecond laser surface processing

We demonstrate the ability to create functionalized microfluidic channels using femtosecond laser surface processing (FLSP). FLSP is an emerging advanced manufacturing technology used to modify the surface properties of materials directly and permanently by producing self-organized quasi-periodic micro- and nano-scale surface features along with surface and subsurface chemical and grain structure changes. We demonstrate on Hastelloy X that by controlling the laser fluence and pulse count, the depth of the microchannels and height of the FLSP microstructures within the microchannels can be controlled independently.

Monosubstituted diphenylsilanes and synthesis thereof

A method for forming monosubstituted diphenylsilanes is broadly provided. The method involves reacting diphenylsilane with an alcohol in the presence of a catalyst and a strong base activator. The reaction results in high selectivity to addition at only one hydrogen site.

Method and system for recovering filler material

A method of recovering filler material from a polymer material comprises (a) heating the polymer material to a first temperature; (b) heating the polymer material to a second temperature higher than the first temperature resulting in a pyrolyzed material; (c) elutriating the pyrolyzed material to obtain a separated mixture; and (d) filtering the separated mixture to obtain the filler material.
