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.

Brownian simulations and unidirectional flux in diffusion [PDF]

Physical Review E, 2005
Brownian dynamics simulations require the connection of a small discrete simulation volume to large baths that are maintained at fixed concentrations and voltages. The continuum baths are connected to the simulation through interfaces, located in the baths sufficiently far from the channel. Average boundary concentrations have to be maintained at their

Generating Diffusions with Fractional Brownian Motion

Communications in Mathematical Physics, 2022
AbstractWe study fast/slow systems driven by a fractional Brownian motion B with Hurst parameter $$H\in (\frac{1}{3}, 1]$$ H ∈ ( 1 3 , 1

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.

Dual‐Mode Magnetic Elastomer for On‐Demand Motion and Degradation

Advanced Functional Materials, EarlyView.
A dual‐mode magnetic elastomer is introduced, enabling DC field‐driven programmable actuation and AC field‐driven magnetothermal degradation. GHz‐range magnetic fields generate ultrafast heating of magnetic nanoparticles that activates cleavage of the silicone elastomer matrix.

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}〉.

Near‐Infrared Light‐Driven Zn/Au Janus Micromotors for Multiplex SERS Detection of Anticancer Drugs

Advanced Functional Materials, EarlyView.
Zn/Au Janus micromotors, propelled by thermophoretic effects under NIR light, function as active SERS platforms for single and multiplex detection of anticancer drugs. Their dynamic motion enhances analyte exchange at the Au interface, reducing saturation and competitive adsorption, thereby improving sensitivity and extending the linear detection range.
