Abstract Zirconium has certain application advantages compared with other metals due to its high density, volume calorific value and combustion performance. Unfortunately, the applications of current powders are limited electrostatic discharge sensitivity, making more pyrophoric less amenable functionalization. To improve security, Zr/NC composite particles reduced sensitivity prepared by solve...

In this work the solubility of metastable α-form and stable β-form L-Glutamic acid in pure water different water/ethanol mixtures at high concentrations ethanol is measured by analytical gravimetric method. The experiments are carried out over a temperature ranging from 283 to 343 K. experimental results show that lower than regardless solvent studied (water or mixtures). also highlight both po...

Abstract Microfluidic processes are of great interest for the production nanoparticles with reproducible properties. However, in real systems, it is difficult to completely exclude incidental larger particles, which can contaminate product or clog downstream process modules. A class microfluidic filters was devised eliminating particulate contamination multistage continuous‐flow processes. To a...

Particle size reduction is effective in increasing the dissolution rate and bioavailability of poorly water-soluble drugs. However, obtaining microparticles without a distribution or even with narrow difficult conventional methods, such as milling antisolvent precipitation. In novel method used this study, uniformly sized droplets drug solution were first prepared on polydimethylsiloxane film, ...

A pressure decay method is used to measure the overall and individual solubilities of multicomponent gas mixtures in different polyethylenes. The new apparatus was validated using literature data, then solubility components realistic mixtures. This data were estimate interaction parameters Sanchez–Lacombe Equation State, which turn model co- antisolvent effects mixture components. need for this...
