The Stochastic‐Dissipative Störmer Problem‐Trajectories and Radiation Patterns

open access: yesAnnalen der Physik, EarlyView.
We consider charged particle motion and radiation in a dipole magnetic field, in the presence of friction and of stochastic forces. The numerical solutions of the Langevin equation reveal how these forces modify the complex dynamics of particles, and they offer some new insights into the nonlinear processes relevant to planetary radiation belts ...

Gypsum Gardens: Self‐Assembled Tubular Structures of Calcium Sulfate with Relevance for the Detection of Extraterrestrial Life

open access: yesAngewandte Chemie International Edition, EarlyView.
Chemical gardens are self‐assembled architectures with “life‐like” morphologies that form in the absence of any biological activity. Here we show that such structures can also be obtained by contacting reservoirs of calcium and sulfate ions, under conditions that plausibly emulate those prevailing on early Mars.

Characteristics of Enhanced Heat Transfer of Nanofluid in Microchannels Under Electric and Magnetic Co‐Excitation

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Due to its small size, microchannel heat exchangers are widely used in fine engineering fields such as electronic equipment. In this paper, the boiling heat transfer characteristics of refrigerants and nanofluids in microchannels are studied by applying electric fields, magnetic fields, and electromagnetic synergistic fields.
