1. Quantitative Surface Enhanced Raman Spectroscopy
Sammanfattning : Surface enhanced Raman spectroscopy (SERS) is a very attractive technique for detection of various organic and inorganic molecules due to its sensitivity and selectivity. The surface enhancement is achieved when the molecules of interest are on or in the vicinity of a metal surface, usually gold and silver. LÄS MER
2. Type Ia Supernova Cosmology : Quantitative Spectral Analysis
Sammanfattning : Type Ia supernovae have been successfully used as standardized candles to study the expansion history of the Universe. In the past few years, these studies led to the exciting result of an accelerated expansion caused by the repelling action of some sort of dark energy. LÄS MER
3. Quantitative Spectroscopy of Gas Phase Reactions at Elevated Temperatures
Sammanfattning : Gas phase reactions at elevated temperatures are versatile tools for material manufacturing and energy conversion. They are of great commercial interest, but they often entail hazardous impacts on the environment. There is consequently a pronounced need for the further develpment of processes utilising these types of reactions. LÄS MER
4. Infrared spectroscopy : Method development and ligand binding studies
Sammanfattning : Infrared spectroscopy detects molecular vibrations and assesses the properties of molecules and their environment. It is a powerful technique to detect ligand induced changes in biomolecules as it has distinct signals and provides different levels of structural information. LÄS MER
5. Quantitative diffuse reflectance spectroscopy : myocardial oxygen transport from vessel to mitochondria
Sammanfattning : In the field of biomedical optics, diffuse reflectance spectroscopy (DRS) is a frequently used technique for obtaining information about the optical properties of the medium under investigation. The method utilizes spectral difference between incident and backscattered light intensity for quantifying the underlying absorption and scattering processes that affects the light-medium interaction.
