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 thin-film of hierarchical rutile/anatase TiO2 nanorod/nanoleafs on fluorine-doped tin oxide glass was produced by the hydrothermal method. Superior specific area, accelerating charge transport and improving charge separation at the junctions of rutile nanorods and anatase nanoleafs resulted in 40% increase in energy conversion efficiency.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.

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.
