science π¬ XPS uncovers surface secrets of bio-materials
Researchers are using X-ray photoelectron spectroscopy (XPS) to study the surface chemistry of bio-based and hybrid materials. This investigation is being conducted by the Fraunhofer Institute for Applied Polymer Research IAP. The analysis focused on biochar made from coffee grounds and orange peels combined with clay minerals and metal oxides, evaluated around the time of the study. Understanding these surface interactions is key for developing functional materials for water treatment and catalysis. This detailed chemical insight helps predict how these complex materials will perform in real-world applications.
