The dynamics and mixing properties of vortex rings obliquely impacting a density interface
… experimental investigation into the dynamics and mixing properties of vortex rings obliquely impacting the density interface in a two-layer density stratification. For turbulent two-layer zero-mean-shear flows, the classical grid-mixing experiments of J.S. Turner (J. Fluid. Mech, 33:639–656, 1968) …

Dynamic nuclear polarization and electron spin resonance in paramagnetic solids at high field
… spin dynamics are consistent with the thermal mixing mechanism of polarization transfer. The high frequency (139.5 GHz, 5T) EPR spectrometer used to perform these experiments is described in detail and several other advancements in the application of high power, high frequency microwave …

Modeling of high fluence Ti ion implantation and vacuum carburization in steel
… was developed to account for diffusion and mixing processes, as well as sputtering and lattice dilation. A Gaussian distribution of Ti was assumed to be incorporated at each time interval. The effects of sputtering and lattice dilation were then included by means of an appropriate coordinate …

Shear induced mixing and self-organization in immiscible alloys during severe plastic deformation
… research focuses on understanding the underlying mechanisms and evolution of the microstructure in Cu-Ag, an immiscible alloy, during SPD. The two key features of SPD processing that will be presented are shear induced chemical mixing of alloying elements at room temperature and self-organization …

Novel Functional Graphene and its Thermodynamic Interfacial Localization in Biphasic Polyolefin Systems for Advanced Lightweight Applications
… graphene. Then, a thermodynamically driven mixing mechanism of the three components is proposed for selectively localizing the additive at the PE/PP interface. The focus is on improving the structural attributes of PE, increasing its industrial value, through the combined effect of micro …

Mixing at Low Reynolds Numbers by Vibrating Cantilevered Ionic Polymers
Creating mixing at low Reynolds numbers is a non-trivial challenge that has been approached from many different perspectives, using passive or active methods. This challenge been further highlighted with the rise of microfluidics. Based on the diminutive size of these devices, the Reynolds numbers …

3-D numerical simulation of reactive extrusion and its application to polymerization of ε-caprolactone in co-rotating twin-screw extruders
… channels were developed based on the conveying mechanisms of the reaction system in the screw channels. Finally, a global model for reactive extrusion was proposed, combining the models for the fully-filled screw elements and the partiallyfilled channels. The predicted conversion ratios at the …

MEASUREMENT OF THE MAGNETIC AND ELECTRIC DIPOLE MOMENTS OF THE $\LAMBDA$ BARYON AT LHCB
… via the Cabibbo-Kobayashi-Maskawa (CKM) quark-mixing mechanism, cannot explain the large observed asymmetry, thus new sources of CP violation, beyond the SM, are expected. A possible way to probe such sources is to search for electric dipole moments (EDMs) of fundamental particles. This thesis …

The in situ generation of liquid crystalline polymer reinforcements in thermoplastics
… method (hereon referred to as the dual-extruder mixing method) was developed to overcome this limitation. In this method, the matrix and LCP polymers were plasticated in two separate extruders, subsequently mixed downstream in a static mixer (Kenics) and the melt blend than passed through an …

Refinement of a Fertiliser-producing Urinal
… element of fertiliser production. The lack of mixing of the contents of this original urinal design would potentially result in a pH gradient, in which localised sections of the urinal would have pH levels below the enzymatic urea hydrolysis threshold (pH 11). Manual mixing was done once a day …

Interaction of Terahertz Radiation with Semiconductor Nanostructures and Quantum Systems
… common interpretation by the classical plasmonic mixing mechanism. I found that the observed phenomenon is due to a new, quantum-mechanical effect, which I called the "in-plane photoelectric effect". This phenomenon, which is described in chapter 5, is observed under conditions where the …
