Scaled Brownian motion: a paradoxical process with a time dependent diffusivity for the description of anomalous diffusion. [PDF]
Physical Chemistry, Chemical Physics - PCCP, 2014 Anomalous diffusion is frequently described by scaled Brownian motion (SBM), a Gaussian process with a power-law time dependent diffusion coefficient. Its mean squared displacement is 〈x(2)(t)〉 ≃ 2K(t)t with K(t) ≃ t(α-1) for 0 < α < 2. SBM may provide a

Intersections of Brownian motions
Expositiones Mathematicae, 2003 A survey of the theory of intersection of Brownian motions is given. The central result of this theory, as is known, is the classical theorem of Dvoretzky, Erdős and Kakutani, which says that ``two independent Brownian motions in \(d\)-dimensional space can intersect if and only if \(d \leq 3\)''.

Deterministic Brownian motion [PDF]
Physical Review A, 1992 The goal of this thesis is to contribute to the ambitious program of the foundation of developing statistical physics using chaos. We build a deterministic model of Brownian motion and provide a microscpoic derivation of the Fokker-Planck equation.

Agglomeration of Nanoparticles Inhibits Solvent‐Driven Ligand Stripping
Advanced Materials Interfaces, EarlyView.This article investigates how solvent quality influences agglomeration and ligand stripping of oleylamine‐coated Fe3O4 nanoparticles using experimental techniques and atomistic molecular dynamics simulations. It demonstrates how poor solvents, such as ethanol, induce nanoparticle agglomeration and hinder ligand stripping through interdigitation.

How to Manufacture Photonic Metamaterials
Advanced Materials Technologies, EarlyView.Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.

Co‐Solvent‐Aided Opto‐Thermophoretic Printing of Gold Nanorod Assemblies
Advanced Optical Materials, EarlyView.A focused laser beam creates a thermal gradient, driving the gold nanorods and polymer coils toward the heated region of the glass substrate, i.e, the laser spot. After the adsorption of the polymer on the gold surface, the nanorods start to assemble onto the surface in a ring‐shaped pattern that grows radially until the beam is turned off.

Advanced Robotics Research, EarlyView.To achieve efficient cancer cell death, a bowl‐shaped PDA@UiO‐66@DOX nanorobot drug‐delivery nanoplatform was developed. Near‐infrared irradiation not only drives the nanorobot to exhibit self‐thermophoretic motion and elevates temperature but also triggers Doxorubicin (DOX) release via hyperthermia, enhancing cancer cells uptake of DOX and thereby ...
