We present a microscopic theoretical analysis of time and spatially resolved photoluminescence of naturally occurring quantum dots induced by monolayer fluctuations in the thickness of semiconductor quantum wells. The analysis is based on a recently develo ...
A wind-tunnel experiment was designed and carried out to study the effect of a surface roughness transition on subfilter-scale (SFS) physics in a turbulent boundary layer. Specifically, subfilter-scale stresses are evaluated that require parameterizations ...
In recent years, superhydrophobic surfaces have attracted a considerable amount of attention from the academic and industrial communities. This growing interest is mainly caused by the fundamental physico-chemical theoretical aspects that remain obscure an ...
The high-temperature wettability of AlN particle preforms with pure molten Cu, Al and Ph is quantified by means of drainage curves measured during pressure infiltration. By integrating the drainage curves obtained in this study, the work of immersion for e ...
In this project, we intend to use inkjet-based delivery of functional liquid droplets on pre-structured surfaces for the directed (self-)assembly of micro/nano-objects as experimental platform to build up and validate multi-level models of micro-droplet de ...
The use of nanomaterials has been shown to be promising in potential applications such as magnetic storage devices, nano-optical devices and sensors, amongst others. Such applications require the disposition of nanoparticles, of a wide variety of materials ...
Correlations between adhesion hysteresis and local friction are theoretically and experimentally investigated. The model is based on the classical theory of adhesional friction, contact mechanics, capillary hysteresis, and nanoscale roughness. Adhesion hys ...
Manipulating biological samples in microliter droplets has vast potential in molecular diagnostics. We present a system for the two-dimensional (2D) magnetic manipulation of aqueous droplets suspended in silicone oil as a platform for on-chip bioanalysis. ...
The possibility of using surface-adsorbed monolayers on oxidized GaAs single crystals is investigated to explore liquid crystal (LC) wettability and alignment. A technological process is developed to chemically activate the GaAs surface with a view to perf ...
Flow processes in unsaturated fractures considerably differ from flow in rock matrix because of the dominance of gravitational forces, accentuated by variations in fracture geometry. This gives rise to liquid fragmentation, fingering, and intermittent flow ...
