Congratulations:
for 15th of Sha'ban

Muhammad(PBUH): "During the night of 15th Sha'ban the Almighty takes decisions in the matters of sustenance, life, death and welfare of the people".

Muhammad(PBUH): "Shabaan is my month". The holy Prophet(PBUH) used to observe fast during the whole month of Sha'baan.

15th2 The fifteenth night of the eighth month of the Islamic lunar calendar (Mid-Sha'ban) is of great importance because for many historic occasions and significant relevance. This day is celebrated because of the birthday of the 11th grandson of the prophet Muhammad(PBUH), who is to rid the world of tyranny and injustice in the darkest days of misery and transgression. This night is at the same time important for provision of priceless chance for repentance and possible forgiveness.

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:

NiOCo3O4

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.

Cell

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.

VertabraA 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.
