Dispersion of clusters of nanoscale silica particles using batch rotor-stators [PDF]

open access: yes, 2017
Nanoparticle powders added into a liquid medium form structures which are much larger than the primary particle size (aggregates and agglomerates)-typically of the order of 10’s of microns.

Novel 24-slots14-poles fractional-slot concentrated winding topology with low-space harmonics for electrical machine

open access: yesThe Journal of Engineering, 2019
This paper proposes a novel winding layout for the electric machines with fractional-slot concentrated windings (FSCW) using a stator shifting concept, with which all the non-working harmonics can be completely cancelled or significantly reduced and the ...

Simultaneous Tracking of Pseudomonas aeruginosa Motility in Liquid and at the Solid-Liquid Interface Reveals Differential Roles for the Flagellar Stators

open access: yesmSystems, 2019
Bacteria sense chemicals, surfaces, and other cells and move toward some and away from others. Studying how single bacterial cells in a population move requires sophisticated tracking and imaging techniques.
