the objective of this research is characterizing the effect of nano-zinc oxide (nano-zno) dispersions on leach resistance and contact angle of beech wood (fagus orientalis lipsky). the beech wood was cut into standard dimension, and oven dried after treating with nano-zno solution, based on immersion method. three treating nano-zno solution levels: (o, 20000 and 40000 ppm), and two thermal trea...

The leaching reaction kinetics of weathered crust elution-deposited rare earth with mixed ammonium salts was studied. The in uence of concentration of reagents and particle size of ore on leaching rate was investigated. The results showed that the di usion process and leaching rate could be improved by increasing reagents concentration and decreasing leaching owing rate and particle size. The l...
