Complete photoemission experiments, enabling measurement of the full quantum set of the photoelectron final state, are in high demand for studying materials and nanostructures whose properties are determined by strong electron and spin correlations. Here the implementation of the new spin polarimeter VESPA (Very Efficient Spin Polarization Analysis) at the APE-NFFA beamline at Elettra is report...

The interaction between surfaces displaying end-grafted hydrophilic polymer brushes plays important roles in biology and in many wet-technological applications. In this context, the conformation of the brushes upon their mutual approach is crucial, because it affects interaction forces and the brushes' shear-tribological properties. While this aspect has been addressed by theory, experimental d...

Nowadays, GNSS-Reflectometry (GNSS-R) can be a new promising remote sensing tool in the ocean, snow/ice and land surfaces, e.g., vegetation biomass monitoring. Although GNSS-R provides a potentially special L-band multi-angular and multi-polarization measurement, the theoretical vegetation scattering properties and mechanisms for GNSS-R are not understood clearly. In this paper, the GNSS-R vege...

Unlike terrestrial Wireless Sensor Networks (WSNs), communication between buried nodes in WUSNs happens through the ground. Due to the complexity of soil, accurate estimation of the underground signal attenuation is challenging. Existing path loss models mainly rely on semi-empirical and empirical mixing models for calculating the dielectric properties of the soil. In this paper, two existing m...

A spaceborne GNSS reflectometry experiment is to be undertaken by Surrey Satellite Technology Limited with support from the British National Space Centre (BNSC) to investigate the reception of reflected GPS signals off the ocean for oceanography applications. The GPS receiver on the UK-DMC satellite has been modified to accommodate a downward (nadir) pointing high gain antenna, to send sampled ...

Macular pigment is key to the healthy eye. Direct determination of macular pigment optical density using single-wavelength reflectometry with a fundus camera has allowed to identify changes in macular pigmentation in patients with dry or exudative macular degeneration. This approach could be useful for individualised patient follow-up, particularly in those with age-related macular degeneration.
