‎‎ماه ضیافت الله:‬

مبارک باد

حدیث قدسی یا أحمَدُ: لَیْسَ شَيْءٌ مِنَ العِبادَةِ أحَبَّ إلَيَّ مِنَ الصَّمْتِ والصَّوْمِ، فَمَن صامَ ولَمْ یَحْفَظْ لِسانَهُ کانَ کَمَن قامَ ولَمْ یَقْرَأ في صَلاتِهِ.

ای احمد: هیچ عبادتی نزد من محبوب‌تر از خاموشی و روزه نیست؛ پس اگر کسی روزه بگیرد، ولی مراقب زبان خود نباشد، مانند کسی است که به نماز بایستد ولی نماز نخواند.

‎‎رمضان هو الشهر التاسع من السنة القمرية في الذي أنزل فيه القرآن للإرشاد عن طريق الوحي إلى نبي الإسلام^(ص). رمضان ماه میهمانی خدا یا ضیافت الله است که در آن اضافه بر پذیرایی جسم، روح انسان نیز به طور عملی توسط پروردگار آموزش می بیند تا پاک شده و ارتقاء یابد.

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.

NiCoCrAlY/CoNiCrAlY Coatings:

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.

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.
