Nitroxide‐Mediated Photo‐Polymerization: A Swiss Army Knife for Microfluidic Design
Advanced Materials Technologies, EarlyView.This article illustrates the application of NMP2 to the rapid (less than 1 h) photostructuring and sealing of model structures intended for microfluidic applications. Remarkably, the careful design of resin composition allows completing these steps by simply spreading bare monomer (i.e., no added photoinitiator) on top of the bottom layer embedding ...

Mechanical loss of laser-welded fused silica fibers [PDF]
Review of Scientific Instruments, 2006 The mechanical quality factor of a carbon dioxide laser-welded fiber was measured and compared to flame-welded fibers to determine the suitability of laser welding for attaching suspension fibers to test masses in precision experiments. The loss in the fiber was found to be limited primarily by thermoelastic damping and surface loss, rather than loss ...
