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 ...

Dissolution Profile of Nimesulide from Pharmaceutical Preparations for Oral Use
Acta Chimica Slovenica, 2016 Nimesulide belongs to the group of semi-selective COX-2 inhibitors, widely used in solid oral formulations. In the present work the influence of surfactants among other drug excipients, as well as particle size of the active substance and the effects of ...

Dissolution Kinetics of Meloxicam Formulations Co-Milled with Sodium Lauryl Sulfate
Pharmaceutics, 2022 Meloxicam (MLX) is a poorly soluble drug exhibiting strong hydrophobicity. This combination of properties makes dissolution enhancement by particle size reduction ineffective; therefore, combined formulation approaches are required.

Surface‐Volume Scaling Controlled by Dissolution Regimes in a Multiphase Flow Environment
Geophysical Research Letters, 2023 Fluid‐rock dissolution occurs ubiquitously in geological systems. Surface‐volume scaling is central to predicting overall dissolution rate R involved in modeling dissolution processes.

Dissolution Stability Study of Cefadroxil Extemporaneous Suspensions [PDF]
, 2008 Dissolution studies have become matter of great significance because, in most cases, drug dissolution is the rate-limiting step in the absorption process.

Rate controls on silicate dissolution in cementitious environments
RILEM Technical Letters, 2017 The dissolution rate of silicate minerals and glasses in alkaline environments is of importance in cementitious systems due to its influences on: (a) early-age reactivity that affects the rate of strength gain and microstructure formation, and/or, (b ...

The Alkaline Dissolution Rate of Calcite [PDF]
The Journal of Physical Chemistry Letters, 2016 Due to the widespread presence of calcium carbonate on Earth, several geochemical systems, among which is the global CO2 cycle, are controlled to a large extent by the dissolution and precipitation of this mineral. For this reason, the dissolution of calcite has been thoroughly investigated for decades. Despite this intense activity, a consensual value
