for Great Eid Adha


Adam(PBUH)constructed the original Kaaba, which was demolished by the Great Flood at the time of Noah(PBUH). Abraham and Ismael(PBUT)rebuilt the Kaaba on the old foundations. The rites were instituted by Abraham(PBUH)as a way of obtaining perfection.

kabaAbraham and Ismael(PBUT): "Our Lord! Accept from us; surely You are the Hearing, the Knowing.   Our Lord! Make us both submissive to You and raise from our off-spring a nation submitting to You and show us ways of devotion and turn to us mercifully.  You are the oft-Returning to mercy, the Most Merciful."

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.

Biphasic TiO2 nanoleafed nanorod electrode for dye-sensitized solar cell


S. Daneshvar e Asl, S.K. Sadrnezhaad



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.

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.
