Effect of particle size of magnesium silicate filler on physical properties of paper

25-May-2012 | Vipul Singh Chauhan, Nishi Kant Bhardwaj, Swapan Kumar Chakrabarti, The Canadian Journal of Chemical Engineering, 2012

Abstract Fillers are essential component of printing papers to increase the opacity, brightness, and to improve formation and printing properties. As a very little work has been reported so far on magnesium silicate (talc), the study was conducted with the filler of different particle size for ...

Physico-Chemical Effects on the Scale-Up of Ag Photodeposition on TiO2 Nanoparticles

10-Feb-2011 | Sze Chi Chan, Mark A. Barteau, Topics in Catalysis, 2011

We have previously demonstrated that TiO2 nanoparticles can be functionalized by photodeposition with silver or gold particles in the 1–2 nm range presumed to be desirable for catalysis applications. However, the preparation of these samples directly on microscope grids, while conducive to ...
