TL;DR: In this paper, a model based on the elastic-plastic theory and a yield function is used to limit the admissible stresses in a tablet during a compaction cycle, which depends on the first and second invariants of the stress tensor: pressure and stress deviation.

TL;DR: Evaluating the density profile in microcrystalline cellulose (Vivapur 12) compacts obtained at different mean porosity using X-ray tomography technique finds important heterogeneity in density is observed and quantified, and underlined that in the case of pharmaceutical tablets, it is important to differentiate the mechanical properties representative of the total volume tablet and the Mechanical properties that only characterize the tablet surface like the Brinell hardness measurements.

TL;DR: This analysis provides chemical explanations to the historical evolution of cosmetic and painting preparation recipes by quantifying the ester saponification by lead salts by using FT-IR spectrometry.

TL;DR: Mercury porosimetry turned out to be a sensitive technique, able to provide quantitative information about powder flow properties, complemen ted by an evaluation of particles micro porosity and size distribution, in a single step, with only approximating 250mg of bulk powder compared to high quantities needed for other methods.

TL;DR: When the particles are non-cohesive, the Turbula blender perfectly mixes identical beads but segregation occurs for beads of different size after just a few rotations, in conclusion.
