The possibility to arrange and embed magnetic micro- nanoparticles in thin polymer film systems using flat magnetically patterned substrate templates is investigated. In contrast self-organized particle rows forming by applying a homogeneous field, particles adapt the field landscape of substrate's pattern prior crosslinking. Crosslinking then fixes positions polymer. process tested for composi...

Spatially confined liquid crystals exhibit non-uniform alignment, often accompanied by self-organised topological defects of non-trivial shape in response to imposed boundary conditions and geometry. Here we show that a nematic liquid crystal, when confined in a sinusoidal microwrinkle groove, exhibits a new periodic arrangement of twist deformations and a zigzag line defect. This periodic orde...

Abstract. Theoretical and experimental work (Furbish et al., 2021a, b) indicates that the travel distances of rarefied particle motions on rough hillslope surfaces are described by a generalized Pareto distribution. The form this distribution varies with balance between gravitational heating, due to conversion potential kinetic energy, frictional cooling, particle–surface collisions; it from bo...

Abstract A two-dimensional ray model is introduced to realize the non-Markovian speedup evolution of a center massive particle gravitationally coupled controllable environment (multilayer arrangement particles). By controlling environment, for instance by choosing judicious mass environmental particles or changing separation distance each particle, two dynamical crossover behaviors from Markovi...

The relation of tobacco mosaic virus (TMV) to host cells was studied in leaves of Nicotiana tabacum L. systemically infected with the virus. The typical TMV inclusions, striate or crystalline material and ameboid or X-bodies, which are discernible with the light microscope, and/or particles of virus, which are identifiable with the electron microscope, were observed in epidermal cells, mesophyl...

The influence of cement particle-size distribution on autogenous strains and stresses in cement pastes of identical waterto-cement ratios is examined for cement powders of four different finenesses. Experimental measurements include chemical shrinkage, to quantify degree of hydration; internal relative humidity development; autogenous deformation; and eigenstress development, using a novel embe...

Abstract We study a one-dimensional mixture of active (run-and-tumble) particles and passive (Brownian) particles, with single-file constraint, in sawtooth potential. The experience ratchet effect this generates current, which can push against an applied load. resulting system operates as engine. Using numerical simulations, we analyse the efficiency engine discuss how it be optimised. Efficien...

A particle-based method is one of the most commonly used methods for fluid simulations. It has certain advantages over other fluid simulation methods; for example, it is easy to simulate irregular and complex fluid motion with topological changes. However, the surface reconstruction for particles remains a challenging problem. In this paper, we propose a surface reconstruction method for moving...

In a collection of assembling particles that is allowed to reach thermal equilibrium, the energy of a given microscopic arrangement and the probability of observing the system in that arrangement obey a simple exponential relationship known as the Boltzmann distribution. Once the same thermally fluctuating particles are driven away from equilibrium by forces that do work on the system over time...
