Condolences:
                for Anniversary of Ashura

On 10th of Muharram of 61st AHL (~October 20th, 680 ACE), Imam HosseinPBUH(the grandson of Prophet MuhammadPBUH) and his 72 companions heroically resisted an army of thousands sent by the tyrant ruler of their time; until all were martyred. Based on teachings of HosseinPBUH, honorable martyrdom is much better than living under cruelty, injustice and oppression.

ashuraeAn Important Lesson: The event of Ashura has become an inspiration and beacon for future generations not to surrender to tyranny, transgression and deceit. Imam HusseinPBUH has taught lessons of dignity, proud, victory and an everlasting slogan: “Never Ever Disgrace!”

Na Ion Battery:

GA 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.

Abstract 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.

NiCoCrAlY/CoNiCrAlY Coatings:


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

HVOF 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.

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

Ni-Pd-CNTFoamy 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.
