在之前的论文（S. Rana, R. S. Srivastava, M. M. Sorensson and R. D. K. Misra, Materials Science & Engineering B, 2005, 119, 144-151）中，描述了通过结合反胶束和化学水解技术加工由锐钛矿二氧化钛光催化壳和铁酸镍磁芯组成的复合纳米颗粒。本研究证明了未掺杂和掺杂的合成复合纳米颗粒的抗菌性能。掺杂过程包括在大约 400 摄氏度下热处理 20 分钟。复合纳米颗粒的热处理不影响镍铁氧体磁芯的磁特性。
In the previous paper (S. Rana, R. S. Srivastava, M. M. Sorensson and R. D. K. Misra, Materials Science & Engineering B, 2005, 119, 144-151), the processing of composite nanoparticles consisting of a photocatalytic shell of anatase titania and a magnetic core of nickel ferrite by combining reverse micelle and chemical hydrolysis techniques was described. The present study demonstrates the anti-microbial performance of undoped and doped as synthesised composite nanoparticles. The doping process involved heat treatment at similar to 400 degrees C for 20 min. Heat treatment of the composite nanoparticles does not influence the magnetic characteristics of the nickel ferrite core.
