Investigation of the milling route for the development of colloidal suspensions to be used as binder in refractory castables

open access: yesOpen Ceramics, 2023
Refractories castables bonded with CAC (calcium aluminate cement) have a limitation when they are used at high temperature in micro-silica containing system and/or in acidic corrosive environments.

Demixing, remixing and cellular networks in binary liquids containing colloidal particles [PDF]

open access: yes, 2010
We present a confocal-microscopy study of demixing and remixing in binary liquids containing colloidal particles. First, particle-stabilized emulsions have been fabricated by nucleation and growth of droplets upon cooling from the single-fluid phase.

Allergen Inactivation with Colloidal Silica

open access: yesJournal of Oleo Science, 2008
We evaluated the allergen inactivating effect of colloidal silica by performing enzyme-liked immunosorbent assay (ELISA) whose wells were coated with 150 ng/mL of Japanese cedar pollen allergen (Cry j 1) or mite allergen (Der f 2). The allergens were almost 100% inactivated by 100 microg/mL of colloidal silica having a particle size 5 nm, and the ...
