Effect of particles on evaporation of droplet containing particles
The evaporation of droplet containing insoluble particles has grown into an active area of research due to the needs for nanofluids for applications in heat transfer, combustion, and manufacturing desired micro/nano particles in the pharmaceutical industry. The evaporation of droplets containing …

Particles Inside Particles: The Flow of Energy in Quarks, Gluons, and Jets
This thesis presents the author’s work in developing probes of the inner structure of jets in high-energy particle collisions. We begin by introducing QCD and the scattering of partons (quarks and gluons), discussing jets as theoretical and experimental proxies for partonic physics, and presenting …

Janus Particles at Interfaces
… of both polymeric and hybrid Janus particles of well-defined size, shape and functionality and their high potential for applications in colloidal and material science. Soft Janus particles, based on polystyrene-block-polybutadiene-block-poly(methyl methacrylate) (SBM) triblock …

Sintering of small particles
An atomistic approach to modeling the sintering of nanocrystalline alloys has been developed. It has been shown that there exist alloys that exhibit both nanostructured stability and undergo an accelerated sintering process [1], [2]. However, the widespread adoption of such alloys has been limited …

Coagulation between fractal aggregates and small particles and fractal properties of marine particles
… aggregates (200-1000 μm) and small (1.48 μm) particles were studied for collisions induced by differential sedimentation and turbulent fluid shear. The collision frequency functions (beta) between these aggregates and small particles were found to be lower than predicted by a rectilinear …

Computer simulations of tapered particles
… simulations of systems of soft repulsive tapered particles. Essentially, the objective of the project was to investigate the effect that changing the degree of taper of these particles has on the collective behaviour of the system. The particle shapes were modelled using the parameterised Gaussian …

Reentrainment of Submicron Solid Particles
… on the short-term reentrainment of submicron particles. The particles tested are in the size range of 10-900 nm and are deposited by wetting the inside of capillary tubes with a liquid suspension. The tubes are then dried in a desiccator. The particles are reentrained under turbulent dry air …

Fluid surface reconstruction from particles
Outlined is a new approach to the problem of surfacing particle-based fluid simulations. The key idea is to construct a surface that is as smooth as possible while remaining faithful to the particle locations. We describe a mesh-based algorithm that expresses the surface in terms of a constrained …

THE MICROSTRUCTURES OF ESTUARINE PARTICLES
… The surface areas and porosities of the particles were determined using BET theory and capillary models applied to the gas adsorption isotherms. The surface areas of the suspended particles collected on axial transects of the Tamar Estuary ranged between 8 and 22 m²/g. The highest values …

Combustion of fine magnesium particles
… prompted studies of combustion mechanisms for particles of such alloys with different Al/Mg ratios. Reference experiments with pure Al and Mg powders are also desired to better understand and model combustion of the respective alloys. While combustion of pure Al powders has been addressed in …

Suspended Particles as Photoelectrochemical Systems
… the fundamentals concerning three types of fine particles that can serve potentially as minute photoelectrochemical reaction centers in form of suspensions have been carried out for InP powders, colloidal CdS, and tris(2,2'-bipyridine)ruthenium(II) complex assembled in particles of zeolite X in …

Geometric Mechanics of Active Particles
… for active systems, where constituent active particles provide energy input at the microscopic level, the emergence of symplectic structure is investigated. In the presence of overdamped forces and torques, inertial forces are negligible and time-evolution become purely kinematical in nature. …

Controlled synthesis of magnetic particles
Magnetic particles have been used for many applications demanding a broad range of particles morphologies and chemistries. Superparamagnetism is advantageous over ferromagnetism because it enables us to control and recover magnetic nanoparticles during and after chemical processing. …
