Large-area wet-chemical deposition of nanoporous tungstic silica coatings

Abstract

We report on a facile procedure for the synthesis of nanoporous coatings of tungstic silica through wet-chemical deposition and post-treatment of tungsten-doped potassium silicate solutions.

Two‐step ion‐exchanged soda lime silicate glass: Effect of surface compression on silver ion release

“…[3][4][5] Self-disinfecting surfaces are an alternative solution to the use of disinfectants for reducing microbial activity; different strategies have been proposed for anti-bacterial applications: for instance, coating the glass surfaces with a layer containing active eluting agents such as silver, copper, tungsten or zinc nanoparticles, or introducing silver directly to the glass composition. 3,[6][7][8][9][10][11] Most prominently, Ag + release from the glass surface is a practical method to prevent microbial activity 1,12,13 . While introducing silver to the glass composition significantly increases the production cost, covering the glass surface with silvercontaining coatings, using, for example, sol-gel methods, is economically favorable.…”
