Condolences:
                for Anniversary of Ashura

On 10th of Muharram of 61st AHL (~October 20th, 680 ACE), Imam HosseinPBUH(the grandson of Prophet MuhammadPBUH) and his 72 companions heroically resisted an army of thousands sent by the tyrant ruler of their time; until all were martyred. Based on teachings of HosseinPBUH, honorable martyrdom is much better than living under cruelty, injustice and oppression.

ashuraeAn Important Lesson: The event of Ashura has become an inspiration and beacon for future generations not to surrender to tyranny, transgression and deceit. Imam HusseinPBUH has taught lessons of dignity, proud, victory and an everlasting slogan: “Never Ever Disgrace!”

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.

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.
