Comparative study of anharmonicity : Ni „ 111 ... , Cu „ 111 ... , and Ag „ 111 ...

We present a comparative study of the structure and the dynamics of the most close packed surface of Ni, Cu, and Ag from near room temperature up to 0.9Tm , using molecular dynamics simulations and interaction potentials from the embedded atom method. Calculated shifts in the surface phonon frequencies, the broadening of their linewidths, and the variations in the mean square vibrational amplit...

Comparing Graphene Growth on Cu(111) versus Oxidized Cu(111)

The epitaxial growth of graphene on catalytically active metallic surfaces via chemical vapor deposition (CVD) is known to be one of the most reliable routes toward high-quality large-area graphene. This CVD-grown graphene is generally coupled to its metallic support resulting in a modification of its intrinsic properties. Growth on oxides is a promising alternative that might lead to a decoupl...

تاثیردما و زمان اتصال دهی بر ریزساختار سیستم GTD-111/BNi-3/GTD-111 به روش فاز مایع گذرا(TLP)

در این مقاله تاثیر دما و زمان اتصال­دهی بر ریزساختار اتصال فاز مایع گذرای سوپرآلیاژ پایه نیکل GTD-111 مورد مطالعه و بررسی قرار گرفته است. فرایند اتصال­­دهی در دماهای1080، 1120 و °C1160 در زمان­های مختلف انجام گردید و ریزساختار نواحی مختلف اتصال توسط میکروسکوپ نوری و الکترونی روبشی مورد بررسی و تحلیل قرار گرفت. نتایج نشان داد که با افزایش دمای اتصال­دهی از 1080 تا °C1160، زمان انجماد ...

Polycyclic aromatic hydrocarbons (PAHs) are immunotoxicants in fish. In mammals, phase I metabolites are believed to be critically involved in the immunotoxicity of PAHs. This mechanism has been suggested for fish as well. The present study investigates the capacity of immune organs (head kidney, spleen) of rainbow trout, Oncorhynchus mykiss, to metabolize the prototypic PAH, benzo [a]pyrene (B...
