A new coarse-grained model for E. coli cytoplasm: accurate calculation of the diffusion coefficient of proteins and observation of anomalous diffusion. [PDF]

PLoS ONE, 2014
A new coarse-grained model of the E. coli cytoplasm is developed by describing the proteins of the cytoplasm as flexible units consisting of one or more spheres that follow Brownian dynamics (BD), with hydrodynamic interactions (HI) accounted for by a ...

Homotopic solutions for stagnation point flow of third-grade nanoliquid subject to magnetohydrodynamics

Results in Physics, 2017
The prime intention here in this investigation is to report the influences of Brownian diffusion and thermophoresis in stagnation point flow towards a nonlinear stretching surface. Magnetohydrodynamic (MHD) third grade fluid is considered.

Controlling particle currents with evaporation and resetting from an interval

Physical Review Research, 2020
We investigate the Brownian diffusion of particles in one spatial dimension and in the presence of finite regions within which particles can either evaporate or be reset to a given location.

Smoluchowski diffusion equation for active Brownian swimmers [PDF]

Physical Review E, 2015
We study the free diffusion in two dimensions of active-Brownian swimmers subject to passive fluctuations on the translational motion and to active fluctuations on the rotational one. The Smoluchowski equation is derived from a Langevin-like model of active swimmers, and analytically solved in the long-time regime for arbitrary values of the P clet ...

Gram‐Scale Production of Iron Oxide Rubik‐Cube Nanoparticles: New Tools for the Clinical Translation of Magnetic Hyperthermia and Magnetic Particle Imaging

Advanced Functional Materials, EarlyView.
This work reports the first gram‐scale solvothermal synthesis of ‘Rubik's cube’ nanoparticles—cubic, dendritic multicore structures with tuneable sizes and exceptional magnetic heating performance. Featuring iron oxide single‐domain character, with low coercivity fields, high magnetization, and strong MPI signals, they enable viscosity‐independent ...

Strong anomalous diffusion in two-state process with Lévy walk and Brownian motion

Physical Review Research, 2020
Strong anomalous diffusion phenomena are often observed in complex physical and biological systems, which are characterized by the nonlinear spectrum of exponents qν(q) by measuring the absolute qth moment 〈|x|^{q}〉.
