Liquid–liquid phase separation in alkali-borosilicate glass. An impedance spectroscopy study

We followed the first stages of liquid–liquid phase separation in an alkali-borosilicate glass by complex impedance spectroscopy at constant temperatures below and above the glass transition temperature, Tg. We found a new feature of the electrical conductivity behavior: at temperatures below Tg, the electrical conductivity, r, diminished with time, while above Tg, the electrical conductivity i...

In-situ Fabrication of Dialysis Membranes in Glass Microchannels Using Laser-induced Phase-Separation Polymerization

Laser-induced phase-separation polymerization of a porous acrylate polymer is used for in-situ fabrication of dialysis membranes inside glass microchannels. A shaped 355 nm laser beam is used to define polymer membranes of 4-14 μm thickness, which bond to the glass microchannel and form a semipermeable membrane. Differential diffusion through the membrane is observed for fluorescein molecules v...

Quantitative AFM analysis of phase separated borosilicate glass surfaces

Phase separated borosilicate glass samples were prepared by applying various heat treatments. Using selective chemical etching we performed AFM measurement on the phase separated glass surfaces. A quantitative roughness analysis allowed us to measure precisely the dependence of the characteristic size of the phase domains on heating time and temperature. The experimental measurements are very w...

Fabrication of integrated porous glass for microfluidic applications.

This paper presents a method for the fabrication of integrated porous silica layers in microfluidic channel networks by microfabrication techniques. Porous silica is obtained by anodization of silicon, followed by full conversion of the porous silicon network into porous silica by means of thermal oxidation. A series of experiments were performed with various channel layouts to determine the cr...
