Nanoparticles (NPs) are applied in a wide range of processes, and their use continues to increase. Fluidization is one of the best techniques available to disperse and process NPs. NPs cannot be fluidized individually; they fluidize as very porous agglomerates. The objective of this article is to review the developments in nanopowder fluidization. Often, it is needed to apply an assistance meth...

Abstract Annotation. Nanopowders of aluminum oxide silicon and iron with silver coating were produces by the radiation-chemical method. The dimensions nanoparticles 50 to 80 nm, area can be changed from 2-3%, up 40%. Was carried out validation antibacterial properties against E.coli staphylococcus. Were estimated photocatalytic nanopowders, which showed applications perspective as a agent. Cyto...

pure barium zirconate nanopowders were successfully prepared in wet-chemistry synthesismethod, using barium stearate and tetra-n-butyl zirconate as ba, zr sources and stearic acid ascomplexing reagent. the gel was calcined at 800 and 900 °c in air. results of thermal analysisare given, including both dtg and tg. fourier transform infrared spectrometry (ftir), x-raydiffraction (xrd), transmissio...

Lead zirconate titanate (PZT) nanopowders with spherical-shaped morphology, perovskite structure and an average size of 20 nm were successfully synthesized. The prepared PZT nanopowders were characterized by differential thermal analysis (DTA), X-ray diffraction (XRD), scanning electron microscopy (SEM), Energy dispersive X-ray (EDS) and Transmission electron microscopy (TEM) technique. Single-...

Abstract Nanopowders doped with silver were produced by the methode pulsed electron beam evaporation.

The incorporation of a minor amount of carbogenic nanoparticles into powder compositions imparts remarkable colour-tuneability, without compromising the flowability. In a proof-of-concept demonstration we report the use of these hybrid nanopowders for the visual enhancement of latent fingerprints where they effectively resolve issues arising from poor contrast against multi-coloured or patterne...

Nanopowders are applied in a wide range of processes, and their use continues to increase. Fluidization is one of the best techniques available to disperse and process nanoparticles. However, nanoparticles cannot be fluidized individually; they fluidize as very porous agglomerates. Often, it is needed to apply an assisting method, such as vibration or microjets, to obtain proper fluidization. I...
