The Micropropulsion Group of the department of Space Systems Engineering of the Delft University of Technology is developing resistojet thrusters for small satellites operating on the vapourisation of liquid water via an electric heater and its subsequent expansion via a nozzle into vacuum for the generation of thrust. As the water vapour...

This thesis proposes the introduction of a metastable equilibrium state in a viscoelastic pre-curved beam. Generally, metamaterials with bistable unit cells need an external application of force to restore, leading to the contemplation of possible structures with self restorable behaviour. Such restorable nature is associated with metastable...

This research focuses on the stability of three metastable ? titanium alloys – Ti-10V-1Fe-3Al (Ti-1013), Ti-10V-2Cr-3Al (Ti-102Cr3) and Ti-10V-2Fe-3Al-B (Ti-1023B). In the first stage of the work, new ?+(?+?) heat treatment schemes were designed on the basis of Thermo-Calc® simulations and previous research work and carried out to such an extent...

Photovoltaic energy is one of the key components of a sustainable energy future. While the market is currently dominated by crystalline silicon solar modules, thin-film silicon technology holds the promise of a cheap, resource-efficient and versatile alternative. The major drawback of thin-film silicon PV is its relatively low conversion...

Hydrogenated Amorphous Silicon (a-Si:H) is a very promising solar cell material with a good potential to use in many applications, as it is cheap to produce, light-weight and flexible. However, upon prolonged exposure to light, the layers suffer from both metastable and irreversible changes (the Staebler-Wronski effect) that have a bad effect on...

Reflection on open-ended and metastable architecture. Metastability is a term which describes the extended duration of certain equilibria acquired by a complex system when leaving its most stable state after an external action. The parameters of such "excited" system may eventually reach and hold stationary values (a metastable state) but then,...

This thesis studies precipitation processes in the Aluminium 7000 series using quantum mechanical total energy calculations. The emphasis is laid on studying the energetics of the various transient phases involved in precipitation of the 5 most important strengthening precipitates. Bulk, strain and interface effects are studies separately, in...
