Properties of concrete containing used engine oil
Since last few years cement replacement materials with industrial by-products and agricultural wastes in concrete production are widely used. It imparts positive environmental effect because the waste materials are not released to the environment. It was reported that the leakage of motor oil onto concrete surfaces in old grinding units increased the resistance such concrete to freezing and tha...
متن کاملcontrol of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولShort-term safety and risk evaluation of engine oil enriched by high concentrations copper nanoparticles on the skin
Abstract Objective(s): Copper nano particles are added to ordinary engine oil as an additive to reduce friction and repair damaged surface under friction conditions. However, it is still unclear what environmental effects such a compound might have on conventional engine oils and its toxicity in different animal species has not been determined. The aim of this study is to investigate the ...
متن کاملBiological Synthesis of Copper/copper Oxide Nanoparticles
Metal nanoparticles have gained significant interest in the past decade because of their unique physio-chemical properties which has a potential to be used in a wide range of applications. Recent efforts have gained success in synthesising nanoparticles with excellent shape and size control; however they are largely restricted to chemical methods. There is an increasing focus on eco-friendly ‘g...
متن کاملEVALUATION OF ANTIBACTERIAL PROPERTIES OF POLYLACTIC ACID-POLYCAPROLACTONE-CONTAINING HYDROXYAPATITE AND ZINC OXIDE NANOPARTICLES IN HARD TISSUE ABSORBABLE SCAFFOLDS
Today, many people need to use bone grafts and implants because of damage to bone tissue. Due to the stimulation of the immune system after implantation, infection at the operation site is very common, which causes swelling and pain in the operation area. The use of zinc oxide nanoparticles reduces infection at the operation site and reduces the patient's need for antibiotics. In the present st...
