Precipitation of ultrafine particles using liquid antisolvent with concentric ultrasonic nozzle and subcritical CO2
… water soluble. Two processes namely, liquid antisolvent precipitation using ultrasonic nozzle and other process using subcritical CO_2 have been used to produce ultrafine particles of this drug. In liquid antisolvent precipitation, a combination of ultrasound, polymer and surfactant is used …

Supercritical fluid spray processes for microencapsulation and formation of submicron aqueous dispersions of pharmaceutical compounds
Precipitation with a Compressed Fluid Antisolvent (PCA) and Rapid Expansion from Supercritical Solution (RESS) are two processes based on supercritical fluids that are capable of producing submicron particles. Novel variations of these basic processes have been examined to produce stable particles …

Formulation development of a novel antivirulence compound for enhanced pharmacokinetic properties
… nanometers have been successfully produced using antisolvent precipitation- ultrasonication method. C790 nanoparticles, in the form of suspensions, have exhibited remarkably enhanced dissolution rate which obtained almost 100% release within 5 minutes under in-vitro sink environment. The …

Characterisation of turbulent mixing and its influence on antisolvent crystallisation
… it can control product quality and distribution. Antisolvent crystallisation is one such process which is strongly influenced by mixing. The initial mixing controls the distribution of supersaturation which in turn controls the nucleation rate and hence many key parameters such a particle size …

Design and Optimization of Angiogenic, Antibacterial Si-Zn-Hydroxyapatite for Use as Filler Particles in Polycaprolactone Nanocomposites
… stable ion-doped HAp was synthesized via aqueous precipitation. Co-doping with silicon and zinc (Si-Zn-HAp) was optimized through control of stoichiometry and processing conditions, and this work extended the previously reported Zn solubility limit in HAp, enabling the formation of continuous …

Precipitation of micro/nanoparticles in enhanced high energy dissipation mixing systems
… local rate of energy dissipation in the mixing precipitation zone where crystals are formed, thus promoting the formation of micro/nanoparticles, In this work, a submerged impinging jet system placed inside the tank was used in combination with another energy dissipation device, i,e., a …
