An Experimental Study on Wear Performance of Electrolytic Multilayer Cu-Ni-Cr Coated ABS Under Different Test Forces

Oxidation resistance of graphene-coated Cu and Cu/Ni alloy.

The ability to protect refined metals from reactive environments is vital to many industrial and academic applications. Current solutions, however, typically introduce several negative effects, including increased thickness and changes in the metal physical properties. In this paper, we demonstrate for the first time the ability of graphene films grown by chemical vapor deposition to protect th...

The Effect of Different Dopants (Cr, Mn, ‎Fe, Co, Cu and Ni) on Photocatalytic ‎Properties of ZnO Nanostructures

   ZnO structures with different dopants (1mol% Cr, Mn, Fe, Co, Cu and Ni) have been synthesized via a simple hydrothermal method using sucrose as a template. These doped ZnO nanostructures characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and photoluminescence (PL). The photocatalytic property of these synthesized materials was studied by a pho...

Fabrication of the Cu-Zn multilayer and Cu-Zn alloy by accumulative roll bonding (ARB) with an emphasis on the wear behavior

Accumulative roll bonding (ARB) was used to fabricate the Cu-Zn multilayer and Cu-Zn solid solution. A lamellar structure with the hardness of about 130 VHN was formed after eight ARB cycles. Following to the suitable heat treatment, a solid solution with a uniform microstructure and hardness of about 57 VHN was produced. The dominant wear mechanism in the ARB processed multilayer was found to ...

the relationship between self-awareness and learners’ performance on different reading comprehension test types among iranian efl elementary learners

یادگیری یک فرایند چند بعدی است که حیطه های مختلف شناختی، رفتاری، و عاطفی را شامل می شود. از آن جا که حیطه ی عاطفی ریشه در هیجانات و احساسات و حتی بر اساس برخی مطالعات خودآگاهی فراگیران دارد، محقق این مطالعه را بر اساس مدل هوش هیجانی دانیل گلمن انجام داده است. در این تحقیق توانش خودآگاهی به عنوان یکی از متغیرها دارای سه مولفه: خودآگاهی هیجانی، خود ارزشیابی صحیح، و اعتماد به نفس می باشد که ارتب...
