             Demise of Prophet Muhammad^(PBUH)
              Martyrdom of Imam Hassan^(PBUH)

After ten years of stay in Medina on June 8, 632 the Prophet fell ill and died after a few days of illness. According to existing traditions the last words on his lips were advice concerning slaves and women. On the Islamic calendar, the anniversaries of the deaths of the prophet Muhammad and his grandson, Hasan, are held on the same date.

Imam Hassan^PBUH): "Allah has made the month of Ramadan the racetrack of His creatures so that they will compete with each other in acts of obedience to Him to attain His satisfaction. Some people preceded others and could win, while others dropped behind and failed. How strange that who plays and laughs on the day when the good-doers are rewarded and the wrongdoers are losing! By Allah, I take the oath, if the cover is removed, man will realize that the good-doers are engaged in their advantages and the evildoers are engaged in their sins.".

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.

Recent Article:

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.
