atemehPBUH

Some enemies of Islam  had mentioned that Muhammad(PBUH) would be without posterity. Then, Fatima was born in Mecca, and Surah Al-Kauthar was revealed: «Indeed, we have granted you al-Kawthar. So pray to your Lord and sacrifice to him alone. Indeed, your enemy is the tailless

                                         

chris1 In an episode in which Muhammad(PBUH) proposed an ordeal of mutual adjuration to a delegation of Christians, Fatimah, according to the "occasion for the revelation" of the following verse, was among those offered by Muhammad(PBUH) as witnesses and guarantors. In verse 23 of Surah Ash-Shura of Quran, Allah teaches the holy profit to say: “I do not ask you any reward for carrying my mission, except loving my relatives.”

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.

Synthesis and characterization of supportless Ni-Pd-CNT nanocatalyst for hydrogen production via steam reforming of methane

Ni-Pd-CNTFoamy 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.

Porous shape memory dental implant

 

We produced bifurcated bone-like shape memory implant with desirable tooth-root fixation capability by compact-sintering of TiH2–Ni-ureamixture. 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.
