Development of new alumina precipitation routes for catalysis applications

(a) Specific surface area and (b) pore volume evolution with micromixing time of boehmite and NH 4 -dawsonite derived alumina prepared with different fast contacting mixers

On the contrary, for AACH-derived alumina case, it seems that sintering occurs at constant mean pore diameter in the temperature range 500 °C to 1000 °C, while pore volume

Since the maximal micromixing time achieved was 180 ms in the SSMD, it could be assumed that such local viscosity was obtained in the mixing zone, preventing

In any case, the presence of shear stress at the ceramic side, near the joint interface, in combination with the ten- sile stresses that are present, may cause cracks in the joint,

The effect of the residual stresses on the strength of joints fabricated between alumina–alumina or alumina and the nickel base alloy HAYNES  214 TM using a solid-state

Inspired by [MT12], we provide an example of a pure group that does not have the indepen- dence property, whose Fitting subgroup is neither nilpotent nor definable and whose

A perfectly flat, infinite surface does not give any diffusely scattered light, any amount of scattered light will therefore signal the presence of surface roughness,

While alumina is known to possess considerable amount of both Lewis and Brønsted acid sites, most of the MOF’s including MIL-53 offers only weaker Lewis acid sites in a comparatively
