Congratulations

Congratulations:

Day of first revelation

The great event happened when Mohammad^(PBUH) received a Quranic verse transferred by the angel Gabriel to him in the cave named Hira. He then proclaimed being the messenger of God with the command to advise the people towards prosperity and salvation.

Read: in the name of that who created. Created the man from a clot. Read; and thy Lord is the most bounteous. That who taught using the pen. That who taught the man what the man knew not.

New Cathode Material

Na Ion Battery:

Na₃MnCO₃PO₄(NMCP)/reduced graphene oxide (rGO) nanocomposite was synthesized by one-step hydrothermal method. The produced 25 nm NMCP nanoparticles were randomly distributed on rGO sheets. As a promising cathode material for Na-ion batteries, the hybrids deliver gravimetric discharge capacities of 98.3 mAh per gram of electrode (156.0 mAh per gram of NMCP) and 114.0 mAh per gram of electrode (180.9 mAh per gram of NMCP) at C/30 and C/100 rates, respectively.

In-situ synthesis of porous g-C₃N₄/SnO₂ catalyst by fast microwave-assisted method was done. Sn derivatives in the condensation step triggered simple pyrolysis of urea to C₃N₄. The visible-light catalyst had high potential for clean energy production.

Sprayed Coatings

NiCoCrAlY/CoNiCrAlY Coatings:

Cyclic oxidation characteristics of HVOF thermal-sprayed NiCoCrAlY and CoNiCrAlY coatings at 1273 K

NiCoCrAlY coating is more resistant to 1000°C air-oxidation than CoNiCrAlY. The main protecting phase on NiCoCrAlY is α-Alumina. Oxidation of CoNiCrAlY initially is sub-parabolic; while finally parabolic.

Ni Nanocatalyst

Recent Article:

Synthesis and characterization of supportless Ni-Pd-CNT nanocatalyst for hydrogen production via steam reforming of methane

Foamy nanocatalysts of Ni-Pd-CNT were synthesized by electroless deposition method. BET results indicated specific surface areas as high as 611.3 m²/g for Ni-Pd-CNTs. TPR and TPO activation energies reduced with addition of Pd-CNT to the Ni foam. At 850 °C, Ni-Pd-0.1CNT nanocatalyst increased methane conversion rate up to 85 %. Ni-Pd-0.1CNT resulted in 22% higher methane conversion than Ni-MgO catalyst.
