Congratulations:
                Happy Birthday

Imam RezaPBUH): "Seven desires without seven deeds is self-mockery: asking of God's forgiveness without heartily repentance; asking God's help without undertaking effort; making firm resolution to doing something without taking due precautions; asking God for paradise without enduring the related hardships; beseeching deliverance from the hell-fire without refraining from lusts; remembering God without anticipating to encounter him".

Imamreza1 Imam RezaPBUH): "An intellect Muslim does not mature unless: benevolence be expected from him, people be secure of him, considers small benefaction of others as plentiful, takes plenty of his own benevolence as meager, does not get tired of demands asked to be fulfilled, does not get fatigued of seeking knowledge, loves poverty more than plentifulness, loves abjectness in the way of God more than the honor on the course against God, likes anonymity more than fame, reference others as better than himself".

TiO2 surface nanostructuring for improved dye loading and light scattering in double-layered screen-printed dye-sensitized solar cells

afm-torabi Surface-nanostructured TiO2 nanorods with ‘crack-like’ surfaces that resemble burnt charcoal were synthesized hydrothermally. The charcoal-like nanorods had higher-specific surface area, 20 % higher dye loading and higher diffuse reflectance than smooth surface nanorods. The efficiency of a screen-printed double-layer dye-sensitized solar cell based on the charcoal-like nanorods was 7.29 %.

Fig. 4 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.
afm-torabi 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.

Enhanced dye loading-light harvesting TiO2 photoanode with screen printed nanorod-nanoparticles assembly for highly efficient solar cell

Vol. 169, 1 July 2015, 395–401

nio-16nmTiO2 nano assemblies consisting of nanorods and nanoparticle attachments were hydrothermally synthesized and their characteristics and light scattering properties were determined. Distinct NR-NPs morphology indicated multiple wave trapping and strong light scattering which was as high as 89.2%. Improvements in NR-NPs DSSCs performance were obtained because of lower resistance to charge transfer (10.07 Ω) and faster diffusion of electrolyte ions (1.22 Mho).
