Direct epoxidation of aromatic nuclei by cytochrome P450 monooxygenases is one of the major metabolic pathways of arenes in eukaryotes. The as-prepared high entropy oxides possess five highly dispersed metal species, and the average particle size is approximately 5 nm, which is the smallest nanometer size of the high entropy oxides that has been reported so far. Die Erfindung betrifft eine Vorrichtung zur Imprägnierung von Einzelfasern (5), Einzelfäden oder Einzelrovings mit einem Matrixmaterial, umfassend ein mit dem Matrixmaterial getränktes poröses Material (3) sowie eine Dosiereinrichtung, um Matrixmaterial in das poröse Material (3) einzudosieren, wobei eine Einrichtung umfasst ist, mit der die zu imprägnierende Einzelfaser (5), der zu. Nano-scale Fe oxides are redox sensitive and have a strong affinity for OC (Coward et al.
