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...

We present experimental investigations of electroosmotic pumping using porous borosilicate glass and various low ion density liquids. The orking liquids were deionized water, deuterium oxide (heavy water), methanol, acetone, acetonitrile and a 1 mM sodium borate buffer as a ontrol. We measured ionic conductivity and, as a useful comparative reference, the zeta potential generated by these liqui...

This chapter presents the chosen aspects of the ion exchange technological method. Results of research refer to the refractive index profiles of planar waveguides produced by the ion exchange method in various glasses. All refractive index profiles were determined by measuring the effective refractive indices of the waveguide modes. In the first part of this chapter the processes of electrodiff...

The local environments around Ti, Cr, and several light rare-earth elements (La, Ce, and Nd) were investigated by in-situ XANES spectroscopy in a number of complex borosilicate glasses and melts (to 1120 °C) that are used for nuclear waste storage. Examination of the high-resolution XANES spectra at the Ti K-edge shows that the average coordination of Ti changes from ~5 to ~4.5. Cr is dominantl...

Recent surge in additive manufacturing efforts demonstrate stereolithography as a promising technique for fabricating glass materials due to the high speed and scalability of process. However, little have been devoted manufacture borosilicate by stereolithographic One challenges is that its relatively low softening temperatures could interfere with thermal post-printing process introduce poor f...

It is well known that silver nanoparticles have been used for centuries as a yellow tint for glasses, which made the silver a revolutionary colorant used to paint the windows of the religious places. An ion exchange non-conventional process comely called medieval pigment without using molten salts has long been used as a method for coloring the glass. In the same subject, this work aims to stud...

Glasses containing metallic nanoparticles are promising materials for technological applications in optics and photonics. Although several methods are available to generate nanoparticles in glass, only femtosecond lasers allow controlling it three-dimensionally. In this direction, the present work investigates the generation of copper nanoparticles on the surface and in the bulk of a borosilica...
