An interlaboratory investigation of intrinsic dissolution rate determination using surface dissolution [PDF]

European Journal of Pharmaceutics and Biopharmaceutics, 2020
The purpose of this study was to conduct an interlaboratory ring-study, with six partners (academic and industrial), investigating the measurement of intrinsic dissolution rate (IDR) using surface dissolution imaging (SDI) equipment. Measurement of IDR is important in pharmaceutical research as it provides characterising information on drugs and their ...

Dual-barrel conductance micropipet as a new approach to the study of ionic crystal dissolution kinetics [PDF]

, 2013
A new approach to the study of ionic crystal dissolution kinetics is described, based on the use of a dual-barrel theta conductance micropipet. The solution in the pipet is undersaturated with respect to the crystal of interest, and when the meniscus at ...

Experiment and simulation study on dissolution widening of carbonate rock fracture

Shuiwen dizhi gongcheng dizhi
Previous researches show that the dissolution of carbonate rocks can be characterized by dissolution rate equation, but the form of characterization is quite different, which is mainly reflected in the undersaturated state far from equilibrium.

Holistic approach to dissolution kinetics : linking direction-specific microscopic fluxes, local mass transport effects and global macroscopic rates from gypsum etch pit analysis [PDF]

, 2013
Dissolution processes at single crystal surfaces often involve the initial formation and expansion of localized, characteristic (faceted) etch-pits at defects, in an otherwise comparatively unreactive surface.
