Improving industrial processes such as filtration of colloidal suspensions requires an in depth understanding of colloidal stability that is linked to interparticle interactions. One way of investigating such phenomena is to determine colloidal phase

Publikováno v: Powder Technology. 255:74-79

Porous extrudates consisting of a packing of model spherical alumina particles with different median diameters (1.7 μm and 19 μm) were prepared. Peptized boehmite and aluminophosphate binders were used in order to ensure the cohesion of the materia

Publikováno v: Cement and Concrete Research. 36:71-78

The prime objective of the plug-and-abandon operations is to provide zonal isolation for infinite time. Cement-based materials are generally used as plugging materials. Therefore, it is important to understand the physical and chemical processes caus
