1393: joy, cheer, prosperity and peace

Norooz (the 1st day of Iranian year):
In harmony with rebirth of the nature, the beginning of the Persian solar calendar which coincides with the first day of spring is a brilliant opportunity to wish health, bliss, prosperity and peace for all human kind.

Solar Cell:

‏         Fabrication of dye sensitized
         solar cell by titanium oxide
         nanostructures
     
Low- cost high-efficiency light absorber
materials for generation of electricity
and disinfection of water.

Degradation of dye contaminants under UV light illumination and enhancement of charge separation efficiency, charge carriers lifetime, photocatalytic activity and interfacial charge transfer by coupling of semiconductors have helped fabrication of new type of photoelectrochemical system using nanostructured substances with great consideration of efficiency and cost of manufacture.

Titanium Scaffolds:

‏         Fabrication of biocompatible
         titanium scaffolds using
         space holder technique

Foamy titanium scaffolds of excellent attachment and proliferation cell properties needless of surface preparation were fabricated by 100 % titanium hydride and space holder utilization. Well-controlled spherical pores with mechanical property improvement were achieved by the newly developed technique.

Amorphous SnO film deposited from electron beam vapor converted into nanocrystalline Romarchite and tetragonal SnO₂ by heat treatment. Doping led to a fine and uniform morphology with less Sn clustering during cycling. Anodic behavior of the thin film SnO₂ during charge/discharge exersize showed that Zn-dopping nearly doubled the specific capacity of the pure SnO₂.
