A simple one-step spraying method to produce poly(vinylidene fluoride) (PVDF) in the desired conformation is presented. The content of piezoelectric ?-phase measured at different spray drying conditions and during electrospray. influence a strong electrical field charges on droplet are investigated separately from electrospray setup with pneumatic atomizer. For this purpose, electric integrated...

A real-time analysis of secondary organic aerosol (SOA) particles formed from cyclohexene ozonolysis in a smog chamber was performed using a laser-ionization single-particle aerosol mass spectrometer (LISPA-MS). The instrument obtains both size and chemical compositions of individual aerosol particles with a high time-resolution (approximately 2 s at the maximum). Both positive and negative-ion...

This paper describes a collaborative theoretical and experimental research effort to investigate the performance of co-axial atomizers utilized in pharmaceutical tablet coating when atomizing common tablet coating solutions under typical processing conditions. In pharmaceutically relevant applications, the liquids being atomized are typically complex, non-Newtonian fluids which may contain poly...

Aim of the present study was to characterize the process of atomization and drying of layer-by-layer emulsions containing lecithin (single layer emulsion) and lecithin/chitosan (multilayer emulsion) and the oxidative stability of the spray-dried emulsions during storage. For this purpose, the analysis of the emulsion spray droplet size during atomization by two different atomization devices, i....

A procedure for the determination of the total content of arsenic in urine, serum and blood by electrothermal atomic absorption spectrometry (ETAAS) is described. Zeeman correction is used to compensate the high background signals. The samples are diluted (1 + 1 for urine and 1 + 3 for both serum and blood samples) in a medium containing 0.1% w/v Triton X-100 before being introduced directly in...

An acute allergic reaction in a 5-year-old healthy male, after receiving midazolam by intranasal atomizer for sedation purposes in the dental clinic, was reported. Shortly after the midazolam was provided, the child developed urticaria in both ankles, which rapidly progressed to the lower extremities, stomach, back, arms, neck, and face. The periorbital skin also became edematous. In the emerge...

This study proposes a two-color laser-induced fluorescence (LIF) technique for measuring the temperature distribution of an airflow by spraying a mist of a fluorescent dye. The mist is generated by using propylene glycol, the vapor pressure of which is much lower than that of water, as the solvent of the fluorescent dyes. A supersonic moisture chamber is used as the atomizer for seeding the tra...
