Sammanfattning : Chlorophylls comprise one of the most important families of molecules for the photosynthetic process. Chlorophyll-like molecules have been classically interpreted under the Gouterman model, being thought to feature two independent transitions, Qy(S1) and Qx(S2). LÄS MER
2. Aqueous self-assembly behaviour alteration derived from primary structure changes of model peptidesMaster-uppsats, Lunds universitet/Kemiska institutionen
Sammanfattning : Understanding of the self-assembly behaviour of peptides is of great interest within several different areas such as neurodegenerative diseases, biotechnology, and peptide pharmaceuticals. In this work we have compared the impact on the self-assembly behaviour derived from systematic changes of the primary structure of A8K, where A denotes alanine and K lysine. LÄS MER

Sammanfattning : Multi-spectral imaging is a powerful approach in spectral analysis of objects with spatial details. However, such approaches are most often time consuming and experimentally complex since both spectral and spatial information in two dimensions are to be resolved. LÄS MER

Sammanfattning : Femtosecond pulse shaping is a versatile tool that enables the generation of ultrashort laser pulses with nearly arbitrary temporal shapes. Among others, the technique is of use in ultrafast spectroscopy experiments where it can be employed for dispersion control and the generation of well-deﬁned laser pulse sequences. LÄS MER
- Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik
Sammanfattning : Recently, new spectroscopic techniques have been developed such as photocurrent detected two-dimensional spectroscopy , which measure the response from a sample that is excited by a high intensity laser pulses. The responses are linear and nonlinear signals that have very different amplitudes; the linear signal can be from 103 to 105 times larger than the nonlinear signal. LÄS MER
