synthesis of 3-aryl-2h-benzo[b]-1,4-oxazines in [omim]bf4 and reduction of organic compounds in methylimidazolium formate
در این پروژه ترکیبات 3-آریل-2h-بنزو[b]-4،1-اکسازین ها از مواد اولیه تجاری مشتقات دو آمینو فنول و ?-هالو کتون های آروماتیک در مایع یونی 1-اکتیل-3-متیل ایمیدازولیوم تترا فلورو بورات([omim]bf4) سنتز شده است. این واکنش توسط باز پتاسیم کربنات محلول از طریق o-آلکیلاسیون و سپس یک واکنش آمیداسیون درون مولکولی خود بخود در مدت زمان کوتاه انجام می شود. ترکیبات 4،1-بنزوکسازین به این روش با بهره خوب تا آلی ...
15 صفحه اولTensile strength of dentin after bleaching treatment.
The mechanical properties of dentin are changed after bleaching, although the effects of the bleaching conditions on the tensile strength of dentin have not been determined. In the current study, a tensile test of bovine dentin was conducted after bleaching and the effects of the bleaching conditions were investigated, including the number of bleaching times, the location where the bleaching ag...
متن کاملTensile Strength of the Eggshell Membranes
STRNKOVÁ JANA, NEDOMOVÁ ŠÁRKA, KUMBÁR VOJTĚCH, TRNKA JAN. 2016. Tensile Strength of the Eggshell Membranes. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 64(1): 159–164. The mechanical behaviour of eggshell membranes under tensile loading has been studied. Samples from diff erent bird species (hen, goose and Japanese quail) have been used. Samples were cut out of the m...
متن کاملUltimate tensile strength of tooth structures.
OBJECTIVE This study determined the ultimate tensile strength (UTS) of enamel (E), dentin (D) and dentin-enamel junction (DEJ) using the microtensile technique. It was hypothesized that the UTS of dental structures varies according to location and nature. METHODS Intact occlusal enamel surfaces from extracted human third molars were etched with 37% phosphoric acid and bonded with a one-bottle...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
