Condolences:
                for Anniversary of Ashura

On 10th of Muharram of 61st AHL (~October 20th, 680 ACE), Imam Hossein^PBUH(the grandson of Prophet Muhammad^PBUH) 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 Hossein^PBUH, honorable martyrdom is much better than living under cruelty, injustice and oppression.

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.

Ti6Al4V Bone:

A novel method for fabrication of bone-like Ti6Al4V foamy core@compact 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.

Electrochemical evaluation of nanocrystalline Zn-doped tin oxides as anodes for lithium ion microbatteries

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.

TiO₂ 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).
