A project called NanoQI, funded by the European Union with Horizon 2020 funds, aims to develop an industry-ready, real-time and in-line capable method for characterizing and imaging nano-dimensions of (thin film) nanomaterials in the critical range of 1 to 300 nm on large sample surfaces of more than 500 Ã 500 mm2. The project involves a consortium of eight companies and organizations from five European countries and was initiated on March 1, 2020. The project's mid-term was in September 2021.

NanoQI combines for the first time X-ray reflectometry (XRR) and X-ray diffraction analysis (XRD) as well as broadband hyperspectral imaging (HSI) into a fast, real-time method for quality control in thin film processing that can be directly integrated into the coating equipment. This combination enables equipment operators to access application-relevant properties such as the thickness of individual layers in a coating system, the solid state structure or even derived functional properties ' such as water vapor permeability ' while the coating is still in progress.
