; Thermal stability and long-acting antibacterial activity of phosphonium montmorillonites CAI Xiang(蔡祥... antibacterial activity. The results show that the phosphonium salts are intercalated into Na-MMT, and the basal spacing of P-MMTs is enlarged with the increase of phosphonium salt content or the growth......
system molten metal were calculated. A model for calculating the activity and activity coefficient of the molten ternary system alloys was derived based on Miedema’s model to calculate the formation heat of binary alloys, and Toop’s equation to calculate the excess free energy of ternary system solution. The activity coefficient and evaporation rate of the elements in Ti-6Al-4V alloy were also......
Article ID: 1003-6326(2005)05-1156-05 Preparation of titanium dioxide/silver sulfate powder and its antibacterial activity PENG Bing(彭 兵), YUAN Chun(苑 春), CHAI Li-yuan(柴立元), WEI Shun... with the temperature of heat-treatment increasing from 300℃ to 800℃. The antibacterial activity of the powder was judged in the way of the minimum inhibitory contents (MiCs). When the content of silver sulfate......
