para el mes de banquetes de Dios
Diciendo Sagrado: O Ahmad; para mí no hay adoración es más caro que el silencio y el ayuno; también el que está en una forma rápida, pero no se ocupa de su lengua, es como un orante que dice que su oración sin la recitación.
Noveno mes lunar del calendario islámico se llama "Ramadán". Para orientación de la gente, el Corán fue revelado, en este mes, hasta el corazón del profeta (paz sea con él). Ramadán es el mes de la fiesta del Dios en el que los seres humanos no sólo están sujetos a la hospitalidad física de que el Señor, pero están entrenados para la limpieza espiritual y actualización.Li Ion Battery:

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.

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.

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.

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.
