Congratulations for:
                                   Eid Ghadir

Imam Ali(PBUH): "All piety and devoutness stands between two statements: (a) Never regret for what you have lost and (b) Do not exult for what you have gained." and  "Infuse your heart with mercy, love and kindness. ... Grant people your pardon and your forgiveness to the same extent that you hope God will grant you pardon and forgiveness."

Holy Quran: "O Messenger! proclaim (the message) which hath been sent to thee from thy Lord. If thou didst not, thou wouldst not have fulfilled and proclaimed His mission. And God will defend thee from men (who mean mischief). For God guideth not those who reject Faith." and "Only God, His Messenger and the true believers who are steadfast in prayer and pay alms while they kneel during prayer, are your guardians."

afm-torabi Surface-nanostructured TiO2 nanorods with ‘crack-like’ surfaces that resemble burnt charcoal were synthesized hydrothermally. The charcoal-like nanorods had higher-specific surface area, 20 % higher dye loading and higher diffuse reflectance than smooth surface nanorods. The efficiency of a screen-printed double-layer dye-sensitized solar cell based on the charcoal-like nanorods was 7.29 %.
Fig. 5 A novel method for fabrication of bone-like Ti6Al4V foamy [email protected] shell composite for utilization as substitutive implant for cortical bone having porous core is devetoped. Yield strength and Young's modulus of the prototypes ranged from 501 MPa to 46 GPa in the compact shells and 7 MPa to 2 GPa in the foamy cores of the composite samples.
afm-torabi Amorphous SnO film deposited from electron beam vapor converted into nanocrystalline Romarchite and tetragonal SnO2 by heat treatment. Doping led to a fine and uniform morphology with less Sn clustering during cycling. Anodic behavior of the thin film SnO2 during charge/discharge exersize showed that Zn-dopping nearly doubled the specific capacity of the pure SnO2.

nio-16nmTiO2 nano assemblies consisting of nanorods and nanoparticle attachments were hydrothermally synthesized and their characteristics and light scattering properties were determined. Distinct NR-NPs morphology indicated multiple wave trapping and strong light scattering which was as high as 89.2%. Improvements in NR-NPs DSSCs performance were obtained because of lower resistance to charge transfer (10.07 Ω) and faster diffusion of electrolyte ions (1.22 Mho).
