[ 1 ] - Characterization of nanostructured SnO2 thin film coated by Ag nanoparticles
Nanostructured SnO2 thin films were prepared using Electron Beam-Physical Vapor Deposition (EB-PVD) technique. Then Ag nanoparticles synthesized by laser-pulsed ablation were sprayed on the films. In order to form a homogenous coated of SnO2 on the glass surface, it was thermally treated at 500°C for 1 h. At this stage, the combined layer on the substrate was completely dried for 8 h in the air...
[ 2 ] - Effect of Heat Treatment on Structural and Magnetic Properties of Nanocrystalline SrFe12O19 Hexaferrite synthesized by Co-Precipitation Method
Nanocrystalline strontium hexaferrite (SrFe12O19) powders have been successfully synthesized using the facile Co-precipitation method. The ferrite precursors were achieved from mixtures of strontium and ferric chloride in an aqueous medium without any surfactant and soft template. The as-received powders were calcined at 800 and 1000 ˚C for 2 hours in air. The final powders were characterized b...
[ 3 ] - Synthesis and characterization of nHA-PLA composite coating on stainless steel by dip-coating process for biomedical applications
316L stainless steel is the most commonly used metallic material in the manufacture of orthopedic implants. To achive better properties metal implants often coated with biocomposites. A sol–gel method was used for coating of Poly lactic acid (PLA)/Hydroxyapatite nanopowder (nHA) on stainless steel 316L substrate. The X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) wer...
[ 4 ] - تثبیت نوری ماده سنتزشده زیستی فتوراکتیو ژلاتین توسط تابش لیزر به منظور کاربردهای زیستی فتولیتوگرافی و چاپ سلولی
در این تحقیق که برای اولین بار در ایران انجام گرفته است، ابتدا ماده حساس به نور (گروه فتوراکتیو) و سپس ماده پروتئینی ژلاتین حاوی گروه فتوراکتیو طی یک سری فرآیندهای پیچیده شیمیائی در تاریکی سنتز شدند. این ماده پروتئینی ژلاتین عامل دار حاوی آزیدو آنیلین می تواند تحت تابش میدان الکترومغناطیسی (نورمعمولی، اشعه فرابنفش، LED، لیزر و سایر میدانهای الکترومغناطیسی) تحریک شده و روی سطوح مختلف تثبیت شود و...
[ 5 ] - Characterization and Corrosion Behavior of Hydroxyapatite- Coated Titanium Substrates Prepared Through Laser Induced Liquid Deposition Technique
Titanium and titanium alloys are often used in orthopedic surgery and dentistry because of their especial characteristics such as biocompatibility, mechanical properties, and corrosion resistance. However, their bio- inertness is the most serious drawback for biomedical applications. Therefore, a bioactive coating like hydroxyapatite (HA) is coated on their surface. In this regard, in the prese...
[ 6 ] - Synthesis of Al2O3-ZrO2 Nanocomposite by Mechanical Activated Self-propagating High Temperature Synthesis(MASHS) and Ignited via Laser
By consideration of unique properties of composite Al2O3-ZrO2 such as high toughness, high wear resistant and relative low thermal expansion, in this study, nanocomposite of Al2O3-ZrO2 was produced by Mechanical activated Self propagating High-temperature Synthesis (MASHS) using laser beam for ignition. First Al and ZrO2 powders were mixed in the mole ratio of 1:1 and milled for 1, 3 and 6 hour...
