Half of the medium-size cities of France are slowly disappearing. From social and economical weaknesses, they experience a rang of symptoms such as shrinkage, urban decay, ageing and impoverished populations that directly impact their spatial qualities and their very own identity. They need a spatial …

Materials with semiconducting properties are present in every microelectronic device and form the backbone of our information society. Commonly used inorganic semiconductors are poorly modular and their production is expensive and energetically demanding. Moreover, the use of metals and critical raw …

In this thesis the different aspects of acquiring the complex refractive index of interstellar ice analogues are treated. The ultimate aim of this work is to search for abilities to predict the infrared absorption spectra of these analogues. A key factor in these predictions is the optical influence …

Increasing oil and energy demand asks for higher efficiency when it comes to oil recovery. To increase oil recovery efficiency, pore-scale mechanisms during waterflooding, a common recovery method, have to be better understood. This provides knowledge on the dynamic process during imbibition, which …

This thesis describes how the abundance of CO2 a ects the porosity of H2O:CO2 ice mixtures deposited at di erent growth temperatures ranging from 30 - 70 K. The mixing ratios of the used ice samples H2O:CO2 = 10:1, 4:1 and 2:1 are of astrophysical relevance. Laser optical interference is used to monitor …

The goal of this study was to explain various measurements of atmospheric methane on Mars performed by the PFS instrument on-board the European Mars Express mission and from ground based observations. In order to reach this goal a layer of methane was assumed to exist in porous near surface layers of …
