The structure and quantum state of the reactants have a profound impact on kinetics dynamics chemical reactions. Over past years, significant advances been made in control manipulation molecules with external electric magnetic fields molecular-beam experiments for investigations their state-, structure- energy-specific reactivity. Whereas studies neutrals so far mainly focused weak-field-seekin...

We present the initial results from a simulation of ion behaviour within Cassini’s cosmic dust analyser (CDA) instrument, using an inhouse ion dynamics code. This work is to enable and enhance the detailed interpretation of dust impact ionisation mass spectra returned from the Saturnian system. Early work has already provided insights into the properties of the impact plasma in both lowand high...

Z-Ligustilide was separated and purified from the traditional Chinese medicinal plant Angelica sinensis by high-speed counter-current chromatography (HSCCC). Analytical HSCCC was first used for the systematic selection of the two-phase solvent system. Preparative HSCCC separation was performed with a two-phase solvent system composed of petroleum ether (60-90 degrees C)-ethanol-water at an opti...

Previous results for the shift of the ionisation potential of an atom in a laser field are used to investigate the kinematics of multiphoton ionisation in either a laser beam or a laser pulse. Previous results for a laser beam show essentially no shifts of the 'above-threshold ionisation' peaks in the electron energy distribution and only small widths. Results for a laser pulse show the possibi...
