Controlled Delivery of (-)-Epigallocatechin 3-Gallate as a Therapeutic Strategy for the Degenerative Disc Disease

Degenerative disc disease (DDD) is the accelerated process of intervertebral disc decay (decrease of disc thickness, enhanced cell death, ECM damage and collagen loss etc.), accompanied with pain, as well as structural and functional failure. So far, there are no therapies that can inhibit or even reverse the degenerative progress of this...

Crystallization & Encapsulation in multicomponent mixtures

In this dissertation crystallization and microencapsulation processes are used to produce multicomponent particulate products with different functionalities (improved stability, controlled release, protection from environment, etc.) and their performance is assessed. Additionally, the interactions between the components in the processes are...

Time-of-Flight Mass Spectrometric Analysis of Ionic Liquid Electrospray Emission: Effects of Liquid Constituents and Ion Transport on Emission of Binary Ionic Liquid Mixtures

Ionic liquid ions sources (ILIS) are under investigation for their application in micro-propulsion for small spacecraft as well as their potential bene?ts for mass spectrometry. Micro-fabricated ILIS based thrusters have been under investigation at the École Politechnique Fédérale de Lausanne (EPFL), the Massachusetts Institute of Technology,...

Advanced Thin Layer Deposition of Materials for Li-ion Batteries via Electrospray

The remarkable physicist Richard P. Feynman once said, more than fifty years ago: ”the principles of physics, as far as I can see, do not speak against the possibility of maneuvering things atom by atom. It is not an attempt to violate any laws; it is something, in principle, that can be done; but in practice, it has not been done because we are...

Process Intensification in Crystallization: Submicron Particle Generation Using Alternative Energy Forms

Crystallization is one of the oldest separation and product formation techniques that continues to be in use today. Despite its long history, it only started to develop significantly in the past few decades. In this thesis, the application of Process Intensification in crystallization is investigated. Process Intensification is a set of often...

ElectroHydroDynamic Atomisation: Unipolar and bipolar characterisation and modelling

ElectroHydroDynamic Atomisation (or electrospraying) is a way to disperse a liquid into droplets by exposing it to a strong electric field. The resulting droplets are (highly) charged and can exhibit narrow size and charge distributions which is desirable for many applications. In this dissertation a novel method is developed to classify the...

Feasibility Study of an EWICON System using the Self Adjusting Multinozzle Electrospraying Technique

This thesis describes the research which have been conducted on the self adjusting multinozzle electrospraying technique, applied in an electrostatic wind energy converter (EWICON). An EWICON system directly converts wind energy to electrical energy by the displacement of charged droplets in the opposite direction of an electric field....

Electrospray-assisted synthesis methods of nanostructured materials for Li-ion batteries

This PhD thesis focuses on the synthesis of nanostructured materials via an aerosol-assisted route based on electrospraying of liquid precursors. Electrospraying is a powerful technique for the production of nearly-monodispersed, highly-charged droplets. The possibility of tailoring the droplet size, as well as coupling the process to different...

Analysis of Electrospraying as an On-demand Deposition Method

The goal of this thesis was to investigate the stability regime for electrospraying events. First of all, we wanted to use electrospraying as an on-demand volume deposition technology. For this purpose, a well controlled and precise liquid ejection was obtained. Instead of generating a continuous spray with constant flow rate or a constant...

The Electrostatic Wind Energy Converter: Electrical performance of a high voltage prototype

Wind energy is converted to electrical energy by letting the wind move charged particles against the direction of an electric field. The advantage of this type of conversion is that no rotational movement, which occurs in conventional wind turbines, is required. An electrostatic wind energy converter (EWICON) has been developed. Charged...
