عيد الأضحى:

لالعظمى عيد الاضحى

 

آدم (عليه السلام) بناء الكعبة الأصلي، الذي تم تدميره على يد الطوفان العظيم في زمن نوح (عليه الصلاة والسلام). إبراهيم وإسماعيل (عليهم السلام) إعادة بناء الكعبة على الأسس القديمة. وأقيمت الطقوس التي كتبها إبراهيم (عليه السلام) وسيلة للحصول على الكمال.

 

ابراهیم و اسماعیل^(ع): "رَ‌بَّنَا تَقَبَّلْ مِنَّا إِنَّكَ أَنتَ السَّمِيعُ الْعَلِيمُ. رَ‌بَّنَا وَاجْعَلْنَا مُسْلِمَيْنِ لَكَ وَمِن ذُرِّ‌يَّتِنَا أُمَّةً مُّسْلِمَةً لَّكَ وَأَرِ‌نَا مَنَاسِكَنَا وَتُبْ عَلَيْنَا إِنَّكَ أَنتَ التَّوَّابُ الرَّ‌حِيمُ".

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.
