MRI investigation of granular interface rheology using a new cylinder shear apparatus [PDF]

open access: yes, 2009
The rheology of granular materials near an interface is investigated through proton magnetic resonance imaging. A new cylinder shear apparatus has been inserted in the MRI device, which allows the control of the radial confining pressure exerted by the ...

Oxide dispersion strengthened nickel produced by nonreactive milling [PDF]

open access: yes
It is shown that oxide dispersion strengthened alloys can be produced by a postulated nonreactive milling mechanism whereby the dispersoid is trapped at the interface between welding metal powder particles. This interparticle welding is possible because,

Preparation of respirable nanoparticle agglomerates of the low melting and ductile drug ibuprofen: impact of formulation parameters [PDF]

open access: yes, 2016
Ductile and low melting point drugs exhibit challenging behaviour during both particle size reduction and spray drying as considerable amount of heat is involved in both processes.
