Dynamo in Weakly Collisional Nonmagnetized Plasmas Impeded by Landau Damping of Magnetic Fields [PDF]
, 2020 We perform fully kinetic simulations of flows known to produce dynamo in magnetohydrodynamics (MHD), considering scenarios with low Reynolds number and high magnetic Prandtl number, relevant for galaxy cluster scale fluctuation dynamos.

Origin of the DC output voltage from a high-Tc superconducting dynamo
Applied Physics Letters, 2019 Despite their proven ability to output DC currents of >100 A, the physical mechanism which underpins the operation of a high-Tc superconducting (HTS) dynamo is still debated widely.

Inverse pH Gradient-Assay for Facile Characterization of Proton-Antiporters in Xenopus Oocytes
MembranesXenopus oocytes represent one of the most versatile model systems for characterizing the properties of membrane transporters. However, for studying proton-coupled antiporters, the use of Xenopus oocytes has so far been limited to so-called injection ...

Geophysical Research Letters, 2019 In a metal, as in Earth's core, the thermal and electrical conductivities are assumed to be correlated. In a planetary dynamo this implies a contradiction: that both electrical conductivity, which makes it easier to induce current and magnetic field, and

Magnetism, dynamo action and the solar-stellar connection
Living Reviews in Solar Physics, 2017 The Sun and other stars are magnetic: magnetism pervades their interiors and affects their evolution in a variety of ways. In the Sun, both the fields themselves and their influence on other phenomena can be uncovered in exquisite detail, but these ...

Resolved magnetic dynamo action in the simulated intracluster medium [PDF]
, 2017 Faraday rotation and synchrotron emission from extragalactic radio sources give evidence for the presence of magnetic fields extending over ˜ Mpc scales. However, the origin of these fields remains elusive.

The Malkus–Robbins dynamo with a linear series motor
, 2003 Hide [1997] has introduced a number of different nonlinear models to describe the behavior of n-coupled self-exciting Faraday disk homopolar dynamos. The hierarchy of dynamos based upon the Hide et al.

Precessing spherical shells: flows, dissipation, dynamo and the lunar core [PDF]
Geophysical Journal International, 2018 Precession of planets or moons affects internal liquid layers by driving flows, instabilities and possibly dynamos. The energy dissipated by these phenomena can influence orbital parameters such as the planet’s spin rate.

A model for rapid stochastic distortions of small-scale turbulence [PDF]
, 2004 We present a model describing the evolution of the small-scale Navier–Stokes turbulence due to its stochastic distortion by much larger turbulent scales. This study is motivated by numerical findings (Laval et al. Phys. Fluids vol. 13, 2001, p.
