Large scale synthesis of ordered silver nanoparticles for superhydrophobic and anti-icing application

Safaee A., Sarkar D.K., Farzaneh M., Université du Québec à Chicoutimi, CA

Large scale syntheses of ordered colloidal silver nanoparticles have been achieved through solution phase method. These colloidal nanoparticles have been spin-coated on glass substrates and investigated using AFM and UV-Vis spectroscopy. Nearly cubic shape silver [...]

Lotus effect on Al-surfaces

Sarkar D.K., Farzaneh M., Université du Québec à Chicoutimi, CA

Nanostructured patterns have been produced on aluminum surfaces by chemical etching. The density of the nanopatterns increases with the increase of the concentration of the etchent. The patterned aluminum surfaces have been passivated using stearic [...]

Superhydrophobic ZnO nanotowers

Saleema N., Sarkar D.K., Farzaneh M., Sacher E., Université du Québec à Chicoutimi, CA

Superhydrophobic zinc oxide nanotowers have been grown successfully on sodalime glass substrates by chemical bath deposition (CBD). Field emission scanning electron microscopy (FESEM) images have revealed the presence of randomly oriented hexagonal patterned ZnO nanotowers. [...]
