Demise of Prophet Muhammad^(PBUH) Martyrdom of Imam Hassan^(PBUH)

After ten years of stay in Medina on June 8, 632 the Prophet fell ill and died after a few days of illness. According to existing traditions the last words on his lips were advice concerning slaves and women. On the Islamic calendar, the anniversaries of the deaths of the prophet Muhammad and his grandson, Hasan, are held on the same date.

Imam Hassan^PBUH): "Allah has made the month of Ramadan the racetrack of His creatures so that they will compete with each other in acts of obedience to Him to attain His satisfaction. Some people preceded others and could win, while others dropped behind and failed. How strange that who plays and laughs on the day when the good-doers are rewarded and the wrongdoers are losing! By Allah, I take the oath, if the cover is removed, man will realize that the good-doers are engaged in their advantages and the evildoers are engaged in their sins.".

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.
