The article provides an overview of modern data on the main gel bases used in technology semisolid dosage forms. classes gelling substances are characterized. According to data, choice excipient must be justified from point view physicochemical properties active substance, and depends place application gel.

High pressure metal die casting is an extremely dynamic process with widely ranging cooling rates and intensifying pressures, resulting in a wide range of solid fractions deformation simultaneously existing the same casting. These parameters their complex interplay dictate formation microstructural solidification defects. In this study, fast synchrotron X-ray imaging experiments simulating high...

T Slow cooling and long stirring produce particles that are large and spherical, while fast cooling and short stirring produce small, jagged particles that tend to stick together. As a result, the larger particles slide by each other more easily than the smaller ones do, producing a semisolid with less resistance to flow. High-speed videos show that the semisolid advances smoothly and evenly, p...

The aim of this study is to investigate experimentally the microstructural evolution of the joints using ledeburitic AISI D2 Tool Steel parts. The application of a new process of the semisolid joining of two parts of AISI D2 cold-work tool steel is proposed using a partial remelting method. Samples were heated in an argon atmosphere up to 1300°C and held for 10 minutes. Metallographic analyses ...

Semisolid preparations for external application to skin have gained much demand, since it is easily absorbed through the skin layers. Many novel topical dosage forms have been discovered, among which organogels appears to play an important role. Organogels are thermodynamically stable, biocompatible, isotropic gel, which not only give localised effect, but also systemic effect through percutane...
