Congratulations:               

                   Happy Birthday

Imam RezaPBUH): "Seven desires without seven deeds is self-mockery: asking of God's forgiveness without heartily repentance; asking God's help without undertaking effort; making firm resolution to doing something without taking due precautions; asking God for paradise without enduring the related hardships; beseeching deliverance from the hell-fire without refraining from lusts; remembering God without anticipating to encounter him".

Ali1Imam RezaPBUH): "An intellect Muslim does not mature unless: benevolence be expected from him, people be secure of him, considers small benefaction of others as plentiful, takes plenty of his own benevolence as meager, does not get tired of demands asked to be fulfilled, does not get fatigued of seeking knowledge, loves poverty more than plentifulness, loves abjectness in the way of God more than the honor on the course against God, likes anonymity more than fame, reference others as better than himself".

G-P-S Graphitic carbon nitride-hematite nanocomposite was synthesized by the hydrothermal method. The VSM test showed the possibility of guidance of the nanoparticles to the cancer tissue by applying an external magnetic field. The heat generation ability of the nanocomposite by a magnetic field and the possibility of using that in PDT for cancer treatment was experimented.

D-S The thin-film of hierarchical rutile/anatase TiO2 nanorod/nanoleafs on fluorine-doped tin oxide glass was produced by the hydrothermal method. Superior specific area, accelerating charge transport and improving charge separation at the junctions of rutile nanorods and anatase nanoleafs resulted in 40% increase in energy conversion efficiency.

NiCoCrAlY/CoNiCrAlY Coatings:

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.
