1. Pulmonary Drug Absorption : In vitro and in vivo investigations of drug absorption across the lung barrier and its relation to drug physicochemical properties
Abstract : Although, pulmonary drug delivery is a well established means for targeting of drugs to the lungs for the treatment of respiratory diseases as well as for the systemic delivery of volatile anesthetic agents, drug absorption kinetics in the lung have not been subjected to extensive research. The main objective of this thesis was to investigate drug absorption characteristics of the lung barrier, using the isolated and perfused rat lung model and in vivo pharmacokinetic studies in rats.

2. Luminescence properties of flexible conjugated dyes
Abstract : In this licentiate thesis the luminescence properties of two flexible conjugated dyes have been studied. The first, Pt1, is a platinum(II) acetylide chromophore used in optical power limiting materials. READ MORE

3. Cavity enhanced optical sensing
Abstract : An optical cavity comprises a set of mirrors between which light can be reflected a number of times. The selectivity and stability of optical cavities make them extremely useful as frequency references or discriminators. READ MORE

4. Fiber-laser-based noise-immune cavity-enhanced optical heterodyne molecular spectrometry
Abstract : Noise-immune cavity-enhanced optical heterodyne molecular spectro-metry (NICE-OHMS) is one of the most sensitive laser-based absorption techniques. The high sensitivity of NICE-OHMS is obtained by a unique combination of cavity enhancement (for increased interaction length with a sample) with frequency modulation spectrometry (for reduction of noise).

5. Fingerprints of light-induced molecular transients : from quantum chemical models of ultrafast x-ray spectroscopy
Abstract : Absorption of sunlight generates renewable electricity and powers the growth of plants, but also causes severe damage both to synthetic materials and biological tissue. The wildly varying outcomes of these light-induced processes are ultimately determined by much slighter differences in their underlying reaction pathways, induced by the transient properties of short-lived and miniscule molecules; a powerful approach to their detection and characterization is offered by ultrafast x-ray spectroscopy, with identification of spectral fingerprints and further guidance from quantum chemical models.
