Condolences:
for Anniversary of Ashura

On 10th of Muharram of 61st AHL (~October 20th, 680 ACE), Imam Hossein^PBUH(the grandson of Prophet Muhammad^PBUH) and his 72 companions heroically resisted an army of thousands sent by the tyrant ruler of their time; until all were martyred. Based on teachings of Hossein^PBUH, honorable martyrdom is much better than living under cruelty, injustice and oppression.

An Important Lesson: The event of Ashura has become an inspiration and beacon for future generations not to surrender to tyranny, transgression and deceit. Imam Hussein^PBUH has taught lessons of dignity, proud, victory and an everlasting slogan: “Never Ever Disgrace!”

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.

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.

C-doped CuO/g-C3N4 with a unique microstructure, enhanced hotoelectrochemical performance, and considerable photostability is synthesized under microwave irradiation.The product demonstrates 227% photoelectrocatalytic activity enhancement over CuO and ~80% photocurrent retention. The nanocomposite synergistically integrates the advantages of both the constituents, offering a low- cost, efficient photocathode for PEC water splitting, photocatalytic hydrogen evolution, and degradation of pollutants.

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

We 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.
