Antibacterial activity of yellow zinc oxide prepared by high-energy ball milling technique

Size reduction in nanoscale of commercial zinc oxide (ZnO) powder is required to enhance its promising properties. Therefore, milling technique is one of an effective method to produce ultrafine ZnO powder. Milling speed is the important parameter that affected on size reduction of the particles. In this work, commercial ZnO powder was milled at 0, 200, 400 and 600 rpm by high energy ball milling process during 10 min. Surface morphology of...
