Metal and metal oxide nanoparticles have, recently, been widely used in the field of electro chemistry where they have found applications in electroanalysis, electrocatalysis and biocatalysis, especially in sensors and ...

nanocomposites with SiO2. The results indicated that SiO2 nano powders can re-duce wear rate of cyanoacrylate and change its wear mechanism. It was also shown that surface hardness of cyanoacry-late is increased by addition of nano-sized SiO2...

Micro and nano sized powders of CaMnO3 were prepared by the conventional solid state-reaction and sol-gelprocedures, respectively. The X-ray patterns indicated that both types of the powders have orthorhombicsymmetry ...
