Birthday of Prophet & Imam Jafar SadeghPBUT:
MuhammadPBUH was born and lived in Mecca for ~52 years (c. 570–622). He lived in Madinah for 10 other years. His living in Mecca can be divided into two phases, before and after declaration of his prophecy. His father died almost six months before his birth. Due to his upright character he acquired the nickname "trustworthy" and was sought out as an impartial arbitrator.
MuhammadPBUH: “What actions are most excellent? To gladden the heart of human beings, to feed the hungry, to help the afflicted, to lighten the sorrow of the sorrowful, and to remove the sufferings of the injured.” “Be not like the hypocrite who, when he talks, tells lies; when he gives a promise, he breaks it; and when he is trusted, he proves dishonest." "He who will do good to the needy, God will do good to him in this world and the next.”

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:

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.

Design and preparation of nickel-titanium implant for lumbar vertebra

936 (2023), 167969
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.
