Sammanfattning : Flows with evaporation and boiling are abundant in different contexts, such as geophysics, the biomedical sectors, and industrial applications. Spray combustion, boiling bubble flows, oceanic sprays, formation and evolution of clouds, spreading of infectious diseases are all relevant examples where a deeper understanding of phase-changing flows is of great importance.

Sammanfattning : This thesis summarizes work in which time-resolved X-ray diffraction has been used to probe crystalline materials, thereby revealing the dynamics of phonons and phase transitions. X-ray diffraction is the standard tool in investigations of structure on the atomic scale. LÄS MER

Sammanfattning : Different laser based techniques have been used to study lifetimes and spectra of gas phase molecules, and non-linear optical phenomena in condensed phase materials.The lifetimes of several electronically excited states of the diatomic molecules vanadium oxide, VO, zirconium sulphide, ZrS, titanium sulphide, TiS and titanium oxide, TiO have been performed by resonant two-photon ionisation spectroscopy in a molecular beam combined with a time of flight mass spectrometer.

Sammanfattning : When light is used to study structures, the wavelength limits the size of the details that can be resolved. Visible light can be used to investigate structures as small as a micrometre in size. To study smaller structures a shorter wavelength is required. LÄS MER
