Grand canonical Monte Carlo calculations and molecular dynamics simulations are used to investigate binary mixtures confined between chemically patterned surfaces. For certain patterns and surface separations, a surfaceinduced phase consisting of liquid “bridges” joining like-patterned regions of the plates is observed. Furthermore, since these bridges involve liquid-liquid interfaces their sha...
Lightweight nano-composite materials, nano-coatings, nanocatalysts, and nano-structured materials have demonstrated an ability to reduce emissions maximize clean energy production. Nanoparticles play important role in engineering decarbonization for applications, a wide range of nanoparticle synthesis methods been developed include those that enable control over particle morphology. The morphol...
Abstract Stress shielding is known to cause bone refracture or low healing rate in fractured bones. The numerical study of process a transverse tibia was conducted this research reduce the stress shielding. and strain on callus were evaluated when plates different metallic non-metallic biomaterials used. Time varying material properties applied, loading conditions coupled with callus. distribut...
In the present study, small scale effect on critical buckling loads of triangular nano- composite plates under uniform in-plane compression is studied. Since at nano-scale the structure of the plate is discrete, the size dependent nonlocal elasticity theory is employed to develop an equivalent continuum plate model for this nanostructure incorporating the changes in its mechanical behavior. The...
طراحی و سنتز پلیمر های کئوردینانسیونی متخلخل یا چارچوب های فلز- آلی به علت ساختارهای جالب این ترکیبات و قابلیت های کاربردی آنها برای ذخیره و جداسازی گاز، کاتالیز، تشخیص و جداسازی انانتیومرها، خواص مغناطیسی، تنظیم لومینسانس و غیره توجه زیادی را به خود جلب کرده است. اخیرا مشخص شده است که برخی لیگاندهای آلی مسطح صلب مثل ایمیدازول-5،4-دی کربوکسیلیک اسید (h3idc) برای تشکیل چارچوب های فلز- آلی مناسب ...
Zone plates are circular diffraction gratings that can provide diffraction-limited nano-focusing of x-ray radiation. When designing zone plates for X-ray Free Electron Laser (XFEL) sources special attention has to be made concerning the high intensity of the sources. Absorption of x-rays in the zone material can lead to significant temperature increases in a single pulse and potentially destroy...
The following article investigates nonlinear symmetric buckling of moderately thick circular Nano plates with an orthotropic property under uniform radial compressive in-plane mechanical load. Taking into account Eringen nonlocal elasticity theory, principle of virtual work, first order shear deformation plate theory (FSDT) and nonlinear Von-Karman strains, the governing equations are obtained ...
