Magnesium Stearate Surface Coverage on Tablets and Drug Crystals: Insights from SEM-EDS Elemental Mapping.

International journal of pharmaceutics, 2022
Scanning electron microscopy-based energy dispersive X-ray spectroscopy (SEM-EDS) is proposed as a versatile tool for quantifying surface area coverage (SAC) by magnesium stearate (MgSt) on pharmaceutical tablets and particles. Our approach involved fast

The effect of thickness on surface structure of rf sputtered TiO2 thin films by XPS, SEM/EDS, AFM and SAM

Vacuum, 2020
In the current study, silicon was utilized as the substrate material and, then, the TiO2 depositions with 100 nm, 300 nm, 500 nm and 700 nm were done onto substrates as thin films at room temperature by a radio frequency (rf) magnetron sputtering method.

Detection of amorphous-amorphous phase separation in small molecular co-amorphous mixtures with SEM-EDS.

European journal of pharmaceutics and biopharmaceutics, 2020
Amorphicity is one possible way to increase the solubility of poorly water soluble drugs. However, amorphous solids are thermodynamically unstable and tend to recrystallize with material-specific kinetics.
