Glass coating for PDMS microfluidic channels by sol-gel methods.

Soft lithography using polydimethylsiloxane (PDMS) allows one to fabricate complex microfluidic devices easily and at low cost. However, PDMS swells in the presence of many organic solvents significantly degrading the performance of the device. We present a method to coat PDMS channels with a glass-like layer using sol-gel chemistry. This coating greatly increases chemical resistance of the cha...

the sol–gel technique

The sol–gel technique is a highly flexible technique for fabrication of oxide glasses, and various researchers have previously reported fluorescence studies of Er-doped sol–gel films and monoliths. Here we report the fabrication of Er-doped strip-loaded sol–gel silicate waveguides, using a silica–titania–alumina host composition, and Er concentrations up to f1.1=10 Er rcm, for possible applicat...

Introduction to Sol-Gel

Using Sol Gel Technique

This paper presents experimental analysis and results of GaN (being a III-V semiconductor) doped with Ferrite elements synthesized using Sol-Gel technique which are carried out at National Chemical Laboratory, Pune Maharashtra. The GaN is employed as dopant for x=1 and x=5, in the formula Ga(2x) N Fe2(49-x) O3 . A non-spinel ferrite system ( Fe2 O3) is chosen for our study. The XRD (Structural)...

Sol-Gel Derived Titania Coating on Titanium Substrate

     The synthesis of titania via sol-gel method has been widely studied. In the present work, titania was deposited onto a titanium substrat...
