Birthday of Prophet & Imam Jafar Sadegh^PBUT:

Muhammad^PBUH 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.

Muhammad^PBUH: “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.”

Li Ion Battery:

On the functionality of the polypyrrole nanostructures for surface modification of Co-free Li-rich layered oxide cathode applied in lithium-ion batteries

P. Vahdatkhah, S.K. Sadrnezhaad, O. Voznyy

Journal of Electroanalytical Chemistry

No. 914 (2022) 116317

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.

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 H₂as 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.

Porous shape memory dental implant by reactive sintering of TiH₂–Ni-Urea mixture

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.
