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. Canser Treatment:

Graphitic carbon nitride-hematite nanocomposite was synthesized by the hydrothermal method. The VSM test showed the possibility of guidance of the nanoparticles to the cancer tissue by applying an external magnetic field. The heat generation ability of the nanocomposite by a magnetic field and the possibility of using that in PDT for cancer treatment was experimented.New photovoltaic electrode:

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.

Porous shape memory dental implant by reactive sintering of TiH2–Ni-Urea mixture

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.
