Fluidization of nanoparticle agglomerates is a promising technique to process nanoparticles. However, possible elutriation small may cause significant loss bed material. To obtain the behavior under stable operation, in this study fraction silica measured vibro-fluidized bed, which operated for several hours. Among conditions with different fluidizing gas velocities, Ug, and vibration strength,...

Over the last few years, the building industry has been focusing on research, on the construction of passive houses and on the use of natural, local materials that are non-toxic, recyclable and can assure high thermal insulation. Cork is a natural material whose qualities have been known since ancient times and which fully meets sustainability requirements. Cork granulate is a sustainable solut...

Metal nanoparticles (NPs) scatter and absorb light in precise, designable ways, making them agile candidates for a variety of biomedical applications. When NPs are introduced to a physiological environment and interact with cells, their physicochemical properties can change as proteins adsorb on their surface and they agglomerate within intracellular endosomal vesicles. Since the plasmonic prop...

This paper demonstrates the optical trapping of micron-sized gold nanoparticle aggregates GNAs with a TEM00 mode laser at 532 nm and reports the observation of an unusual light-induced agglomeration phenomenon that occurs besides the trapping of the GNAs. The observed agglomerate has a 60–100 m donut-shaped metal microstructure with the rate of formation dependent on the laser power used. Citra...

The impact between particles or agglomerates and a device wall is considered as an important mechanism controlling the dispersion of active pharmaceutical ingredient (API) particles in dry powder inhalers (DPIs). In order to characterise the influencing factors and better understand the impact induced dispersion process for carrier-based DPIs, the impact behaviour between an agglomerate and a w...

This paper presents an investigation of powder dispersion based on a combined computational fluid dynamics (CFD) and discrete element method (DEM) approach. Agglomerates of different particle sizes and polydispersities are dispersed in a cyclonic flow at different flow velocities. The analysis of flow field and agglomerate properties indicates that the dispersion is governed by two competitive ...
