عید مبعث:
مبارک باد
گویی که ز صخره ها صدا می آید
آوای خوش خدا خدا می آید
ای خسته دلان منتظر، گوش کنید
آوای محمد(ص) از حرا می آید
قران کریم:
بخوان به نام پروردگارت که آفرید
انسان را از خون بسته آفرید
بخوان و پروردگارت بزرگوارتر است
اوست آنکه قلم را آموخت
به انسان آنچه نمی دانست آموخت

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.g-C3N4/SnO2 Nanocomposite:

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

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.مقاله جدید
Synthesis and characterization of supportless Ni-Pd-CNT nanocatalyst for hydrogen production via steam reforming of methane
A. Chaichi, S.K. Sadrnezhaad, M. Malekjafarian
International Journal of Hydrogen Energy
43 (2018), 1319-1336
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.
