Congratulations:               

                   Happy Birthday

Imam RezaPBUH): "Seven desires without seven deeds is self-mockery: asking of God's forgiveness without heartily repentance; asking God's help without undertaking effort; making firm resolution to doing something without taking due precautions; asking God for paradise without enduring the related hardships; beseeching deliverance from the hell-fire without refraining from lusts; remembering God without anticipating to encounter him".

Ali1Imam RezaPBUH): "An intellect Muslim does not mature unless: benevolence be expected from him, people be secure of him, considers small benefaction of others as plentiful, takes plenty of his own benevolence as meager, does not get tired of demands asked to be fulfilled, does not get fatigued of seeking knowledge, loves poverty more than plentifulness, loves abjectness in the way of God more than the honor on the course against God, likes anonymity more than fame, reference others as better than himself".

Li

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. PP[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:

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.

Design and preparation of nickel-titanium implant for lumbar vertebra

 

M. Parsafara, S.K. Sadrnezhaad, N.H. Nemati

Journal of Alloys and Compounds
936 (2023), 167969

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.
