Abstract: A coated substrate comprising a coating layer comprising inorganic oxide and pores, the coating layer demonstrates improved durability properties. The coated substrate may for example be used in solar modules.

Abstract: The present invention relates to a multi-layer material sheet comprising an NIR-reflective, translucent polymeric layer having a reflectance of more than 20% of all light with a wavelength from 750 nm to 1000 nm and a transmission of more than 50% of all light with a wavelength from 380 nm to 750 nm and an NIR-reflective, colored polymeric layer having a reflectance of more than 25% of all light with a wavelength from 1000 nm to 2100 nm. The present invention also relates to a backsheet suitable for use in a photovoltaic module, said backsheet comprising said multi-layer material sheet; and to a photovoltaic module comprising said backsheet.

Abstract: The invention relates to the discrimination of spectroscopically different tracer materials by magnetic particle imaging (MPI), based on the differences of the MPI spectral responses of said tracer materials.
