Nanoparticle separation with a miniaturized asymmetrical flow field-flow fractionation cartridge
Asymmetrical Flow Field-Flow Fractionation (AF4) is a separation technique applicable to particles over a wide size range. Despite the many advantages of AF4, its adoption in routine particle analysis is somewhat limited by the large footprint of ...

Advection-dispersion in symmetric field-flow fractionation channels [PDF]
We model the evolution of the concentration field of macromolecules in a symmetric field-flow fractionation (FFF) channel by a one-dimensional advection-diffusion equation. The coefficients are precisely determined from the fluid dynamics.

Field-Flow Fractionation Analysis of Complex Biological Samples [PDF]
Normal analytical methods have difficulties when analysing complex samples containing particles of different size. In the 1960s, a new analytical technique was developed, which was able to overcome those difficulties.

Experimental setup for the ultrasonic fractionation of flowing whole blood in a capillary
If a long ultrasound driving pulse is chosen such, that its frequency is greater than the resonance frequency of one cell type and less than the resonance frequency of another cell type, the cells are separated in different nodes and antinodes of the ...

Conventional dielectrophoresis (DEP) force on cell and particle is altered in the proximity of the electrodes due to the failure of the dipole approximation. In these conditions an anomalous DEP (aDEP) force rules the particle manipulation.

Water-dispersible colloids distribution along an alluvial fan transect in hyper-arid Atacama Desert
As located in one of the oldest and driest deserts on Earth, soils in the Atacama Desert are greatly affected by atmospheric dust deposited on soil surface and the related fate of water-dispersible colloids (WDCs,
