A Study on Antibacteria of Hydroxyapatite Filter

Journal of the Korean Ceramic Society, 2013
A hydroxyapatite air filter was made with hydroxyapatite powder, water and chitosan solution. The structures of the sintered HAp samples were determined by MP-XRD. Hydroxyapatite has antibacteria properties against Staphylococcus aureus, Klebsiella pneumoniae and Escherichia coli. The bacteria removal rate was 99.9%.

Effects of annealing on antiwear and antibacteria behaviors of TaN–Cu nanocomposite thin films

Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 2008
TaN–Cu nanocomposite films were deposited by reactive cosputtering on Si and tool steel substrates. The films were then annealed using rapid thermal annealing (RTA) at 400°C for 2, 4, and 8min, respectively, to induce the nucleation and growth of Cu particles in TaN matrix and on film surface.
