Application of Al/B/Fe2O3 Nano Thermite in Composite Solid Propellant

HTPB-Polyurethane: A Versatile Fuel Binder for Composite Solid Propellant

Fabrication of PGS/CaTiO3 Nano-Composite for Biomedical Application

Biodegradable elastomeric materials are gaining extensive attention in the field of soft tissue engineering. Poly (glycerol sebacate) (PGS) is a novel biocompatible elastomer in this scope. However this polymer has poor mechanical properties especially when the molar ratio of glycerol is higher than sebacic acid. Calcium Titanate (CaTiO3) is a biocompatible ceramic with some degr...

Virtual prototyping of solid propellant rockets

cerns in rocket motor design because of the enormous cost of typical payloads and, in the case of the Space Shuttle and other manned vehicles, for the crew’s safety. In the spring of 1999, for example, a series of three consecutive launch failures collectively cost more than US$3.5 billion. The most notorious launch failure, of course, was the tragic loss of the Space Shuttle Challenger and its...

Integrated Simulation of Solid Propellant Rockets

This paper presents an overview of research activities at the Center for Simulation of Advanced Rockets (CSAR) at the University of Illinois at Urbana-Champaign. CSAR is one of five university-based research centers funded by the U. S. Department of Energy as part of the Accelerated Strategic Computing Initiative (ASCI). The purpose of ASCI is to advance the state of the art in computational si...

extraction and characterization of allium irancum plant extract and its application in the green synthesis of silver nano particles and oxidation of thiocarbony1 compounds

سنتز سبز نانوذرات فلزی (nps) درسالهای اخیر توجه بسیارزیادی را به خود جلب کرده است. زیرا این پروتوکل کم هزینه وسازگار با محیط زیست از روش های استاندارد سنتز. در این پایان نامه ما گزارش میکنیم یک روش ساده و سازگار با محیط زیست برای سنتز نانوذرات نقره با استفاده از محلول آبی عصاره گیاه allium iranicum به عنوان یک عامل کاهش دهنده ی طبیعی. نانو ذرات نقره مشخص شد با استفاده از تکنیک های uv-visible، x...
