Ionization of large molecules with short laser pulses
(2010-03-24)The decay dynamics of fullerenes and polyaromatic hydrocarbons (PAH) after femtosecond-laser excitation have been studied experimentally by electron momentum mapping and mass spectrometry. The electron spectra of fullerenes ... -
Quantitative analysis of tumor growth and response to therapy
(2010-01-14)Modeling the natural growth of tumors is of value for evaluation of tumor progression and optimization of treatment strategies. However, modeling tumor growth based on clinical data is hampered by the limited data available, ... -
Laser Photodetachment of Negative Ions - Fundamental Research and Applications
(2009-05-07)Photodetachment studies of atomic and molecular negative ions in the gas phase are presented. Negative ions are loosely bound quantum systems whose existence is strongly dependent on the correlations between the electrons. ... -
Towards quantitative single cell analysis using optical tweezers and microfluidics
(2009-04-03)Experiments on single cells have the potential to uncover information that would not be possible to obtain with traditional biological techniques, which only reflect the average behavior of a population of cells. In the ... -
Susceptibility effects in MRI and 1H MRS. The spurious echo artifact and susceptibility measurements.
(2009-01-29)When performing magnetic resonance (MR) experiments, a strong homogeneous magnetic field is often preferred, especially in clinical applications. However, all objects that are placed in the magnetic field will disturb the ... -
Studies on the gamma radiation environment in Sweden with special reference to 137Cs
(2008-09-05)Gamma radiation in the environment today mainly originates from naturally occurring radionuclides, but anthropogenic radionuclides, such as 137Cs, contribute in some areas. In order to assess population exposure in case ...
