Europium oxide as a perfect electron spin filter
Essential to the emergence of spin-based electronics is a source of highly polarized electron spins. Conventional ferromagnets have at best a spin polarization P-50%. Europium monoxide is a novel material capable of generating a highly spin-polarized current when used as a tunnel barrier. EuO is …

Spin injection and manipulation in organic semiconductors
… use of organic semiconductors to enable organic spintronic devices requires the understanding of transport and control of the spin state of the carriers. This thesis deals with the above issue, focusing on the interface between the organic semiconductor and the spin source. The morphology of the …

NOVEL TYPES OF TWO-DIMENSIONAL METAL CARBIDES AND THEIR APPLICATIONS: FIRST PRINCIPLES STUDIES
… and oxygen reduction/evolution reaction) and spintronic devices (including spin filter and spin valve) are systematically studied.

Comparison of the growth and monoclonal antibody production of suspended mammalian cells in three perfusion systems
… hollow fiber membrane system, and the external spin filter (ESF) system. The batch experiments for each cell line were used as base case scenarios for the comparisons of cell growth and monoclonal antibody production. The fed-batch experiments for each cell line did not vastly improve the cell …

Growth of spinel oxide thin films for high efficiency room temperature spin filtering
In this thesis, the potential of all-spinel oxide tunnel junctions in the field of spintronics has been investigated. In particular, the suitability of the metallic and superconducting LiTi2O4 as non-magnetic electrode in an almost defect-free CoFe2O4-based spin-filter tunnel junction has been …

Magnetism in Two-Dimensional van der Waals Materials
… by electron tunneling through van der Waals spin-filter magnetic tunnel junctions, where a few-layer crystal of CrX3 serves as the insulating tunnel barrier. Surprisingly, these magneto-optical and tunneling experiments reveal magnetic properties in ultrathin CrX3 differing from those of the …

High density animal cell culture systems using porous supports
… eliminates the need for a separate oxygenator or spin filter for gas exchange. The input gas created a differential pressure drop across the porous draft tube and forced the medium to perfuse through the porous draft tube. A simple mathematical model was formulated to describe the hydrodynamic …
