[ 1 ] - Evaluation of tribological properties of (Ti,Al)CN/DLC composite coatings deposited by cathodic arc method.
In this study, Ti, Al and N doped DLC – referred to here after as “(Ti,Al)CN/DLC composite”- coating and pure diamond-like coating (DLC) were produced by cathodic arc deposition technique and the effects of the coating thickness on their tribological properties were evaluated. The coatings were characterized, using scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray diffrac...
[ 2 ] - بررسی مقایسه‌ای تأثیر افزودن نانوذرات دیوپسید و سیلیکا سولفوریک اسید بر خواص مکانیکی سیمان‌های گلاس آینومر
The aim of the present study is to study the effects of adding diopside (CaMgSi2O6) as well as silica sulfuric acid nanoparticles to ceramic part of glass ionomer cement (GIC) in order to improve its mechanical properties. To do this, firstly, diopside (DIO) nanoparticles with chemical formula of CaMgSi2O6 were synthesized using sol-gel process and then, the structural and morphological p...
[ 3 ] - تهیه و مشخصه‌یابی نانو ذرات شیشه زیست فعال اصلاح سطحی شده توسط عامل زوجی 3- (تری متوکسی سیلیل)پروپیل متا اکریلات
In this study, NBG was successfully achieved through a sol-gel technique, and to further improve its dispersibility, a crylate coupling agent was coupled onto the surface of the NBG. The 3-(Trimethoxysilyl)Propylmethacrylate coupling agent was used to the surface modification of the synthesized NBG by a wet-chemical method in a dynamic inert nitrogen atmosphere. The surface properties of the bi...
[ 4 ] - تأثیر غلظت پیش‌ماده فلزی بر شکل و اندازه نانو ذرات ساخته شده به‌وسیله عصاره گیاه
Bio-inspired silver nanoparticles were synthesized with the aid of a novel method, using leaves of the plant Nigella sativa. After drying the leaves in air, they were first sweltered in boiling distilled water and the liquid was filtered subsequently. The result was the brothused to reduce solutions including various concentrations of silver nitrate in a proper amount of pH. The displayed UV&nd...
[ 5 ] - Fabrication, Characterization and Process Parameters Optimization of Electrospun 58S Bioactive Glass Submicron Fibers
Over the past decades, bioactive glass (BG) has been of a great interest in the bone regeneration field, due to its excellent biocompatibility, bioactivity and osteoconductivity. Herein, fabrication of bioactive glass as one-dimensional fibers by employing an Electrospinning process is reported. The Sol-Gel method was chosen considering the final fibers smoothness and homogeneity. Starting sol ...
[ 6 ] - SYNTHESIS OF HIGH ASPECT RATIO SILVER NANOWIRES: PARAMETRIC STUDY OF THE POLYOL PROCESS
Silver nanowires (AgNWs) are considered as one-dimensional nanostructures, which have received much attention due to their nanoscale size, high aspect ratio, high electrical and thermal conductivity, optical transparency and high mechanical stability. Preparation of AgNWs by polyol process is remarkably sensitive to the interactions between synthesis parameters. In this study, the effect of the...
