تهانينا:
                      لليوم الوحي الأول

وقع حدث عظيم عندما تلقى محمد (ص) آية القرآنية نقلها بواسطة الملاك جبرائيل له في كهف يدعى غار حراء. ثم أعلنت كونه رسول الله مع الأمر لتقديم المشورة إلى الناس نحو الازدهار والخلاص.

اقْرَ‌أْ بِاسْمِ رَ‌بِّكَ الَّذِي خَلَقَ ﴿١﴾ خَلَقَ الْإِنسَانَ مِنْ عَلَقٍ ﴿٢﴾ اقْرَ‌أْ وَرَ‌بُّكَ الْأَكْرَ‌مُ ﴿٣﴾ الَّذِي عَلَّمَ بِالْقَلَمِ ﴿٤﴾ عَلَّمَ الْإِنسَانَ مَا لَمْ يَعْلَمْ ﴿۵)            سوره العلق ۱-۵

Drug Delivery:

Targeted drug delivery from hard tissue implants coated with porous double-layer titanium-oxide nanotubes and polymer nanocords

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.

g-C3N4/SnO2 Nanocomposite:

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:

 

Cyclic oxidation characteristics of HVOF thermal-sprayed NiCoCrAlY and CoNiCrAlY coatings at 1273 K

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.
