Measurement of electric charge of aerosol particles generated by various methods

TL;DR: The charge of aerosols generated by various methods was measured by a visual experimental technique as mentioned in this paper, and the results obtained are as follows: 1) Aerosol particles generated by condensation after evaporation almost reach the Boltzmann charge distribution when ions are mixed as condensation nuclei, but have a lower charge when no ions were mixed.
Journal ArticleDOI

Luminescent Polymer Electrolytes Prepared by Growing ZnO Nanoparticles in the Matrix of Polyethylene Glycol

TL;DR: In this paper, the luminescent nanoparticles inside the polymer matrix are grown instead of dispersing the preparednanoparticles by a mixing process, as is currently used in conventional methods, allowing the sizes of thenanoparticles to be controlled by using different quantities of precursors as well as by adjusting the storage time prior to drying.
Journal ArticleDOI

Aerosol synthesis of self-organized nanostructured hollow and porous carbon particles using a dual polymer system.

TL;DR: This work investigates how the zeta potential of the polystyrene latex particles, and the resulting electrostatic interaction with the negatively charged phenolic resin, influences the particle morphology, pore structure, and CO2 adsorption capacity.
Journal ArticleDOI

High performance electrospinning system for fabricating highly uniform polymer nanofibers

TL;DR: A high performance electrospinning system has been successfully developed for production of highly uniform polymer nanofibers and it was found that the cone jet length observed at the end of the needle during the injection of the precursor solution and the average diameter of the nan ofibers decreased with decreasing Q/I.

Preparation of Ni particles by ultrasonic spray pyrolysis of NiCl2·6H2O precursor containing ammonia

TL;DR: In this paper, the preparation of nickel particles from nickel ammine complex was studied by ultrasonic spray pyrolysis in the presence and the absence of hydrogen, and spherical, solid and well-distributed Ni particles of about 0.5 μm were obtained at a residence time of 7-9 s in the aerosol reactor.
