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.

Hara14
بِسْمِ اللَّـهِ الرَّ‌حْمَـٰنِ الرَّ‌حِيمِ

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

TNT 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.

Abstract 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

HVOF 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.

Porous shape memory dental implant by reactive sintering of TiH2–Ni-Urea mixture

ToothWe produced bifurcated bone-like shape memory implant with desirable tooth-root fixation capability by compact-sintering of TiH2-Ni-urea mixture. The primary constituents of the porous product were Ni and Ti. We could adjust the pores’ shape, size, and interconnectivity for favorite bone ingrowth by using urea as a space holder. Bending tests showed 0.9 mm recoverable deflection for specimens which assisted immediate self-fixation of the implant into the jaw bone cavity.
