From: Antibacterial composite coatings of MgB2 powders embedded in PVP matrix
Preparation of composite MgB2-PVP coatings (I–III), release of active MgB2 from the composite coating and its decomposition in the presence of water/aqueous solution (IV), and the antimicrobial effect through possible mechanisms on different microbes. SEM image from III is taken on the sample (MgB2-PVP)foil0.25.
