Plasma-spraying deposition, like many applications that guarantee a high reproducibility of processes, requires the use of free-flowing powders. In this example, the substrate needs to receive a ...

A high-pressure gas atomization process has garnered an American laboratory at least 16 patents over the last two decades and created a spin-off company. Iver Anderson and Emma White, metallurgists at ...

The synthesis of silica particles, used in bioimaging and drug delivery, could become considerably cheaper and more efficient by adopting a new flow synthesis method which involves a spiral channel ...

Powders are widely used in pharmaceuticals as active ingredients or excipients in formulations. As a result, several production processes are used for handling powders: wet and dry granulation, ...

WEST LAFAYETTE, Ind. – Anyone who has tried to pour powdered sugar into a jar knows that sometimes beating the sides of the container or package is the only way to make it flow. That same process is ...

GREGORY 1 has defined two types of flow in powder agglomerates; ‘stick and slip’ flow and free flow. It is well known that fine particles tend to stick and that larger particles flow more easily.

The uses of rheology are spreading beyond their traditional scope in mechanical engineering. Powder tribology, in particular, is increasingly being used in pharmaceutical formulation. How do powders ...
