The transverse proximity effect in quasar spectra
… alpha forest of neutral hydrogen. This so-called proximity effect has been detected with high statistical significance towards luminous quasars. If quasars radiate rather isotropically, background quasar sightlines located near foreground quasars should show a region of decreased Lyman alpha …

Constraining the UV background with the proximity effect
… forest. This phenomenon is known as the proximity effect and it is the main focus of this thesis. Modelling the influence on the IGM of the quasar radiation, one is able to determine the UV background intensity at a specific frequency (J_nu_0), or equivalently, its photoionisation rate …

The Influence of Contact Transparency on the Superconducting Proximity Effect in Thin Semiconducting Films
The superconducting proximity effect allows for the introduction of pair correlations into otherwise normal metals provided that they are coupled through a sufficiently transparent junction. The influence of this proximity effect manifests itself by modifying both the normal layer sheet resistance …

Growth of amorphous tungsten silicide and study of the proximity effect at low dimensions for superconducting applications
… silicide (WSi). These hybrid devices use the proximity effect to potentially be more efficient than either of the materials alone. In order to make these devices, we first grew high quality samples of tungsten silicide and characterized them before growing hybrid films useful for nanoscale …
