Emergence of Coupled Rotor Dynamics in Metal-Organic Frameworks via Tuned Steric Interactions. [PDF]
J Am Chem Soc, 2021 The organic components in metal–organic frameworks (MOFs) are unique: they are embedded in a crystalline lattice, yet, as they are separated from each other by tunable free space, a large variety of dynamic behavior can emerge.

Atrial Rotor Dynamics Under Complex Fractional Order Diffusion. [PDF]
Front Physiol, 2018 The mechanisms of atrial fibrillation (AF) are a challenging research topic. The rotor hypothesis states that the AF is sustained by a reentrant wave that propagates around an unexcited core.

Quincke rotor dynamics in confinement: rolling and hovering. [PDF]
Soft Matter, 2019 The Quincke effect is an electrohydrodynamic instability which gives rise to a torque on a dielectric particle in a uniform DC electric field. Previous studies reported that a sphere initially resting on the electrode rolls with steady velocity.

Investigation on the Rotordynamic Characteristics of Turbopumps with Angular Contact Ball Bearings
Vibration, 2023 The support stiffness of the turbopump rotor system with angular contact ball bearing varies with the rotational speed, which leads to the inaccurate prediction of the dynamics of the turbopump rotor system.
