Congratulations:

                for Teacher's Day

 

Of one Essence is the human race
Thus has "creation" put the base
One "limb" impacted is sufficient
For all "others" to feel the "mace"

Imam Sajjad(PBUH): The right of teacher on you is to consider teacher great, to respect his session significant, to listen to him well, not to talk to others in his presence, defending him when vilified, covering him from defects, highlighting him for wisdom and avoiding hostility with his friends. If you do all these, angels will favor you with witness of your pure Godly destination and purpose; instead of learning for peoples' sake.

Solar Cell:

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.

In presence of sodium citrate, PVA and K2CO3, mixture of silver oxide and Ag-Ni ANPs was achieved. Stoichiometry of the Ag-Ni ANPs was found strongly dependent on ligands of the reduction reaction. Without any ligand, 100% Ag-Ni ANPs was observed. Using THPC resulted in construction of near-uniform ANPs. NPs having up to 65 % Ni were obtained for the first time in this research.
