How do nanocomposites work?
Nanocomposites are materials that incorporate nanosized particles into a matrix of standard material. The result of the addition of nanoparticles is a drastic improvement in properties that can include mechanical strength, toughness and electrical or thermal conductivity.
What metals are oxides?
Metal oxides are crystalline solids that contain a metal cation and an oxide anion. They typically react with water to form bases or with acids to form salts. MO + H2O → M(OH)2 (where M = group 2 metal) Thus, these compounds are often called basic oxides.
Which of the following method is top-down method for nano materials?
Attrition, milling and etching are typical top down methods. 3.
How do you synthesize zinc oxide nanoparticles?
