Congratulations

Congratulations:

Banqueting Month of God

Sacred Saying: O Ahmad; to me, no worship is dearer than silence and fast; so he who is on a fast, but doesn’t take care of his tongue, is like a praying-one who says his prayer without a recitation.

‬The ninth lunar month in the Islamic calendar is called "Ramadan". For the guidance of the people, the Quran was revealed, in this month, to the heart of the prophet^(PBUH). Ramadan is the month of the feast of the God in which human beings not only are subject to the physical hospitality of their Lord but are trained for spiritual cleanliness and upgrade.‬

New Cathode Material

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

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.

NiCoMgAl2O4 Catalyst

Catalyst for CH₄ 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.

Nanocomposite

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.

NiTi Dental Implant

Recent Article:

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.
