Condolences:
                for Anniversary of Ashura

On 10th of Muharram of 61st AHL (~October 20th, 680 ACE), Imam Hossein^PBUH(the grandson of Prophet Muhammad^PBUH) 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 Hossein^PBUH, honorable martyrdom is much better than living under cruelty, injustice and oppression.

Drug Delivery:

Both hard-tissue replacement and drug-delivery can be achieved via anodic oxidation/electrospun coating in Titanium-implants. The order and size of the titanium oxide nanotubes which facilitate drug-delivery, are both controllable. For prevention of the local bacterial infection, Vancomycin loading is possible. To prevent explosive release, nano-polymeric cords can be placed on the oxidized titanium nanotubes.

In-situ synthesis of porous g-C₃N₄/SnO₂ catalyst by fast microwave-assisted method was done. Sn derivatives in the condensation step triggered simple pyrolysis of urea to C₃N₄. The visible-light catalyst had high potential for clean energy production.

NiCoCrAlY/CoNiCrAlY Coatings:

NiCoCrAlY coating is more resistant to 1000°C air-oxidation than CoNiCrAlY. The main protecting phase on NiCoCrAlY is α-Alumina. Oxidation of CoNiCrAlY initially is sub-parabolic; while finally parabolic.

Foamy nanocatalysts of Ni-Pd-CNT were synthesized by electroless deposition method. BET results indicated specific surface areas as high as 611.3 m²/g for Ni-Pd-CNTs. TPR and TPO activation energies reduced with addition of Pd-CNT to the Ni foam. At 850 °C, Ni-Pd-0.1CNT nanocatalyst increased methane conversion rate up to 85 %. Ni-Pd-0.1CNT resulted in 22% higher methane conversion than Ni-MgO catalyst.
