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.

Optoacoustic‐Guided Magnetic Microrobot Platform for Precision Drug Delivery
Advanced Materials, EarlyView.Optoacoustically guided FePt@ZIF‐8‐based microrobots are designed with high drug loading capacity, controllable locomotion, and deep‐tissue imaging capability. By integrating navigation, drug release, and real‐time monitoring into a single platform, they provide a versatile tool for precise intervention, opening new possibilities for treating ...

The Multiparameter Fractional Brownian Motion
, 2006 We define and study the multiparameter fractional Brownian motion. This process is a generalization of both the classical fractional Brownian motion and the multiparameter Brownian motion, when the condition of independence is relaxed. Relations with the

Emergent Motility of Self‐Organized Particle‐Giant Unilamellar Vesicle Assembly
Advanced Materials, EarlyView.Giant unilamellar vesicles (GUVs), when combined with silica particles under alternating electric fields, spontaneously self‐assemble into motile structures. Asymmetric particle decoration induces fluid flows that propel the assemblies, enabling persistent motion and reversible control.

Haloarchaea swim slowly for optimal chemotactic efficiency in low nutrient environments
Nature Communications, 2020 Brownian motion places the ultimate limit on microorganisms’ ability to navigate. Thornton et al. show that Haloarchaea have a strategy of slow swimming and infrequent reorientation that exploits the randomising nature of Brownian motion to achieve ...

Observation of Topological Chirality Switching Induced Freezing of a Skyrmion Crystal
Advanced Materials, EarlyView.Using Lorentz Transmission electron microscopy, it is shown that in the insulating van der Waals ferromagnet, CrBr3, a magnetic field can cause Bloch skyrmionic bubbles to spontaneously switch their chirality. As achiral type‐II bubbles are an intermediate state, the bubbles rapidly elongate and shrink when switching, thereby inducing a freezing of the

Ultraslow scaled Brownian motion
New Journal of Physics, 2015 We define and study in detail utraslow scaled Brownian motion (USBM) characterized by a time dependent diffusion coefficient of the form $D(t)\simeq 1/t$ .

Advanced Materials Interfaces, EarlyView.Plasma polymerized nanoparticles (PPNs) offer a solvent‐free route to functional nanocarriers with long‐lived radicals. This study establishes design principles for long‐term storage of PPNs, demonstrating that dry‐phase storage retains radical content, covalent reactivity, and bioactivity over extended periods. These findings advance the translational

Shaping Microbial Motion with Light: A Contactless Approach Using Diffusioosmotic Flow
Advanced Materials Interfaces, EarlyView.Light‐controlled, contactless manipulation of cyanobacteria using photoresponsive azobenzene surfactants. Reversible photo‐isomerization generates surface flow, enabling precise trapping, relocation, and directional control of single cells or ensembles with adjustable light intensity and wavelength for noninvasive, spatiotemporally resolved microbial ...
