Condolencias:
para el aniversario de Ashura
El 10 de Muharram de 61 AHL (~ 20 de octubre de 680 ACE), el Imam Hosseinla paz sea con él (el nieto del Profeta Muhammadla 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 Hosseinla paz sea con él, el martirio honorable es mucho mejor que vivir bajo crueldad, injusticia y opresión.

The PPy(polypyrrole)/NP (nanoparticle)/NR(nanorod)/NW (nanowire)@Co-free Li-rich oxide (PPy-NP/NR/[email protected]) composites were prepared. PPy improved the ionic and electronic conductivity of the LMNO cathodes. [email protected] cathode delivered high discharge capacity of 191 mAh g−1, with capacity retention of 96%, after ∼ 200 cycles at 0.1C. Higher capacity and longer cycle-life contributed to the optimized intercalation and doping pseudocapacitive charge storage behaviour.
Catalyst for CH4 reforming:

Methane steam reforming is an assuring reaction using steam to produce H2 as clean energy over a nicκel- based catalyst. We synthesized mesoporous monometallic NiMgAl2O4 and bimetallic NiCoMgAl2O4 catalysts in a two-step combustion method using a mix of fuels and powder metallurgy. The evaluation tests at 750 ◦C showed the bimetallic catalyst has the highest conversion of 99.30% with low carbon deposition of 0.09% after 15 h.
CuO/g-C3N4 nanocomposite:

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.
