Condolencias:
para el aniversario de Ashura

El 10 de Muharram de 61 AHL (~ 20 de octubre de 680 ACE), el Imam Hossein^{la paz sea con él} (el nieto del Profeta Muhammad^{la paz sea con él}) y sus 72 compañeros resistieron heroicamente a un ejército de miles enviados por el gobernante tirano de su tiempo; hasta que todos fueron martirizados. Basado en las enseñanzas de Hossein^{la paz sea con él}, el martirio honorable es mucho mejor que vivir bajo crueldad, injusticia y opresión.

Una lección importante: el evento de Ashura se ha convertido en una inspiración y un faro para que las generaciones futuras no se rindan a la tiranía, la transgresión y el engaño. El imám Hussein^{la paz sea con él} ha enseñado lecciones de dignidad, orgullo, victoria y un eslogan eterno: "¡Nunca Humillado!"

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.

New photovoltaic electrode:

Physica E: Low-dimensional Systems and Nanostructures

Volume 123, September 2020, 114206

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.
