On the fluidization of cohesive powders
Differences and similarities between micro- and nano-sized particle gas–solid fluidization
The fluidization of cohesive powders has been extensively researched over the years. When looking at literature on the fluidization of cohesive particles, one will often find papers concerned with only micro- or only nano-sized powders. It is, however, unclear whether they should

Enhancing colloid stability of polymer microspheres in water through SiO<sub>2</sub> coating
Effects of coating cycles and surface coverage
In this study, we investigated the wettability and agglomeration characteristics of polymer microspheres coated with low-temperature deposited SiO2 in a fluidized bed atomic layer deposition (ALD) setup. Surface characterization revealed the presence of a significant amount of de

Stirrer design for improving fluidization of cohesive powder
A time-resolved X-ray study
Stirring has been recognized in the literature as a promising technique for facilitating fluidization of cohesive powders, via inputting additional energy to counteract interparticle forces. However, the influence of operating conditions and stirrer configurations on flow behavio
