守得云开,FD-SOI工艺迎来爆发期

FD-SOI(全耗尽绝缘硅)是指一种平面晶体管结构。这种平面架构是通过在绝缘硅片晶圆超薄的绝缘氧化埋层(BOX)上再生长一层超薄的单晶硅层来实现的。由于采用超薄硅层,所以不需要沟道掺杂,使晶体管得以全耗尽。此外,薄氧化埋层使得基底偏压功能可以满足功耗/性能以及成本要求。相比传统的硅CMOS(bulk

纪录片《西藏一年》中中国法制化形象的柔性传播

以纪录片《西藏一年》为例,本文分析研究了对华友好人士是如何通过纪录片来影响普通大众对于中国形象、中国法制化形象的理解的;分析研究西方纪录片中有哪些法制传播的理念,进而可以反驳一些不当的误解;分析研究含有中国法制化形象的国外纪录和传播,对于我国做好法制化的对外宣传、展示中国的现代化形象、学习世界的法制理念的大众传播都有重要的意义。     

One-pot Sequential Reaction for the Synthesis of Polysubstituted 3-（3-Nitro-2-phenylchroman-4-yl）-3-arylaminoacrylates

The one-pot sequential reaction of arylamines, methyl propiolate and 2-aryl-3-nitrochromenes without any catalyst in refluxing ethanol afforded the polysubstituted 3-（3-nitro-2-phenylchroman-4-yl）-3-arylaminoacrylates in good yields and with high diastereoselectivity. Reaction mechanism was believed involving the initial formation of β-enamino ester and sequential Michael addition.     

An expedient one-pot synthesis of highly substituted imidazoles using supported ionic liquid-like phase（SILLP） as a green and effcient catalyst and evaluation of their anti-microbial activity

An effcient method for the synthesis of imidazole derivatives by a three-component condensation of benzil or 9,10-phenanthrenequinone,aldehydes and ammonium acetate using supported ionic liquidlike phase（SILLP）catalyst under ultrasonic irradiation or classical heating conditions is reported.The present methodology offers several advantages,such as excellent yields,simple procedures,short reaction times,simple work-up and mild conditions.The catalyst is easily separated from the products by fltration and also exhibits remarkable reusable activity.These highly substituted imidazoles were also evaluated for their anti-microbial activity.
