Objective(s): This study was carried out to boost the pharmacologic influence of carvedilol (CAR) (as a poorly water-soluble drug) by developing CAR-eudragit® RS100 (Eud) nanofibers and nanobeads benefiting an electrospraying approach. Materials and Methods: CAR-Eud nanoformulations with varying ratios (1:5 and 1:10) at total solution co...
This study demonstrates that the hydrodynamic phenomena taking place inside the capillary limits the frequency range of voltage pulses for stable single event electrospraying SEE , when the meniscus/cone size is defined by the inner diameter of the nozzle. For the analysis of SEE, we used a one-dimensional model describing the displacement and oscillations of the liquid inside the nozzle. The f...
The carefully-sized electrospraying of water is an important research problem because of wide use of sprays of water and aqueous solutions in many fields of industry and agriculture. The size of water droplets (or aqueous solutions) and its distribution is essential for various applications of aerosols. The measurement of size of electrosprayed water using laser-based measurement techniques is ...
Carbon nanotubes have been explored as interconnects in solid acid fuel cells to improve the link between nanoscale Pt catalyst particles and macroscale current collectors. The nanotubes were grown by chemical vapor deposition on carbon paper substrates, using nickel nanoparticles as the catalyst, and were characterized using scanning electron microscopy and Raman spectroscopy. The composite el...
A continuous near-field electrospray process has been developed to deposit micropatterns. Different from traditional electrospray technologies, the nozzle-to-substrate distance was shortened to less than 5 mm, and a glass capillary nozzle with a diameter of tens of microns was used. Steady and continuous ejection was achieved, and patterns with line widths of sub-100 μm were generated. The infl...
