Solubility and Crystallization of Piroxicam from Different Solvents in Evaporative and Cooling Crystallization [PDF]

, 2021
In this work, the solubility of a non-steroidal anti-inflammatory drug (NSAID), piroxicam, is investigated. The polymorphic form II, which is the most stable form at room temperature, was investigated in seven different solvents with various polarities ...

Mixing effect of slag compositions and additives on crystallization of mold fluxes for Ti-bearing steels

Journal of Materials Research and Technology, 2021
Increasing titanium content enhances the high temperature corrosion resistance and strength of steel and alloy, whereas it is prone to induce the severe slag/metal reaction during continuous casting, causing great property change of mold flux.

Application of Two-Dimensional Correlation Analysis to Explosives Detection and Polymer Crystallization [PDF]

, 2010
This thesis presents two novel applications of two-dimensional (2D) correlation analysis: (1) long standoff detection of explosives and (2) morphology development in semicrystalline materials. Due to the dangers of improvised explosive devices (IEDs),

Low-Temperature Rheology and Thermoanalytical Investigation of Lubricating Oils: Comparison of Phase Transition, Viscosity, and Pour Point

Lubricants, 2021
According to the ASTM D97, the pour point is the temperature below which petroleum products cease to flow. To evaluate the relevance of pour point measurements for synthetic lubricating oils, we investigated the crystallization, melting temperature and ...
