Using two-pulse photon echo excitation a strong resonance in the measured homogeneous dephasing time as a function of magnetic field is observed in the H-3(4)-D-1(2) transition of Pr3+:YAlO3. The resonance could only be observed at low excitation energies since it otherwise was masked by excitation intensity dependent extra dephasing processes in the crystal. Thus intensity dependent dephasing pro

The electricity sector is in the beginning of a large shift from centralized dispatchable production to distributed variable production. With this necessary change, new challenges arise. One crucial challenge is related to upholding the system balance in the power grid. In this master thesis, a Battery Energy Storage System (BESS) has been implemented in an HVDC-system with large amounts of Wind P

Ultrafast accelerator-based sources combined with synchronized femtosecond lasers are currently being developed. The method described here is intended as a jitter monitor at such facilities. We report on the possibility of extracting a time-offset signal between two different synchronized ultrashort light pulses. The method is based on sum-frequency generation in a nonlinear crystal. Aiming at ext

Synchrotron radiation sources have greatly contributed to the progress in many fields of science. The development of the storage ring technologies has made possible to obtain very low emittance electron beams, which together with the use of undulators allow guiding a very high photon flux into a very small spot required by the experiments. Development of the sources has been accompanied with equa

The goal of this study is to investigate the applicability of asymmetrical flow field-flow fractionation (AsFlFFF)–multi angle laser light scattering (MALLS), and to develop a method for analysis of cationic potato amylopectin (CPAP) having ultrahigh molecular mass (UHMr). Use of the aqueous carrier having low salt content (3 mM NaN3) resulted in a distortion in AsFlFFF fractograms of CPAP with a

The reactions in acidic aqueous solution between thiocyanate and each of the gold(II1) complexes Au(NH,)?+, rrans-Au- (NH,)zC12t, and rrans-A~(NH,)~Br~+ have been studied by use of potentiometric pH measurements and sequential-mixing stopped-flow spectrophotometry. The reactions give a common gold(1) product whereas the rate-controlling steps are different. The reaction between Au(NH,)?+ and thiocThe reactions in acidic aqueous solution between thiocyanate and each of the gold(III) complexes Au(NH3)43+, trans-Au(NH3)2C12+, and trans-Au(NH3)2Br2+ have been studied by use of potentiometric pH measurements and sequential-mixing stopped-flow spectrophotometry.
