Infrared spectroscopy of NaCl(CH3OH)n complexes in helium nanodroplets
Published 2016“…These complexes were formed in liquid helium nanodroplets by consecutive pick-up of NaCl and CH3OH molecules. For the smallest NaCl(CH3OH)n, complexes where n = 1−3, the IR data suggest that the lowest-energy isomer is the primary product in each case. …”

Novel opto-electronic and plastic fibre sensors
Published 1998“…The middle POF is coupled to a red LED and emits light onto a flat target with the two outer fibres receiving the reflected light from the target and guiding it to two silicon PIN photodiodes. Theoretical investigations on the behaviour of the sensor are presented for ranges between 0 mm and 100 mm, and for targets with different reflectivities. …”
