¡Felicidades:

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.

Ramazan3 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.

The PPy(polypyrrole)/NP (nanoparticle)/NR(nanorod)/NW (nanowire)@Co-free Li-rich oxide (PPy-NP/NR/NW@LMNO) composites were prepared. PPy improved the ionic and electronic conductivity of the LMNO cathodes. PPy-NP@LMNO 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:

 

A two step Microwave-assisted coke resistant mesoporous Ni-Co catalyst for methane steam 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.

 

New Nanophotocatalyst:

       Ni0.8Co0.2/Zn0.8Cd0.2S/g-C3N4 ternary nano- photocatalyst for improved visible-light-driven photocatalytic H2 evolution and pollutants degradation

The catalytic performance of Ni0.8Co0.2/Zn0.8Cd0.2S/g-C3N4 is attributed to the formation of a direct Z-scheme heterojunction between Ni0.8Co0.2/Zn0.8Cd0.2S and g-C3N4, which can accelerate the separation and migration of photogenerated carriers. The H2 evolution rate of Ni0.8Co0.2/Zn0.8Cd0.2S/g-C3N4 during the experiments did not significantly decrease, suggesting that Ni0.8Co0.2/Zn0.8Cd0.2S/g-C3N4 exhibits durability. Consequently, this ternary nano-photocatalyst can be a potential photocatalytic material for H2 evolution under visible light.

NiTi Lumbar Vertebra:

 

Design and preparation of nickel-titanium implant for lumbar vertebra

A simple and affordable sintering/braiding technique produced a shape memory Nickel Titanium implant aiming to have outstanding shock absorption, strength, biocompatibility, and cell growth capability for lumbar vertebra substitution. The elastic modulus of the sample was 3.5 GPa, and its compressive strength at 6 % strain was 200 MPa. The alloy was thermoelastic, making it a good candidate for placement in bone tissue. The biocompatibility and non-toxicity of the bone cells, with cell viability of over 4 × 104 cells within 48 h, indicated that the produced implant had suitable cellular biocompatibility.
