介绍了在进入22 nm技术节点后MOSFET器件的两个发展方向,即多栅结构和应变硅纳米线结构.首先通过分析特征长度与有效栅极数量的关系,表明多栅结构器件可以有效增强栅极对沟道
We have directly investigated the chemical state of the Pd species in a realμ-gas sensor device by examining theμ-fluorescence X-ray absorption fine structure
Antibacterial activity of zinc oxide nanoparticles(Zn O-NPs) has received significant interest worldwide particularly by the implementation of nanotechnology to
Mesoporous TiO2/Carbon beads have been prepared via a facile impregnation-carbonization approach, in which a porous anion-exchange resin and K2TiO(C2O4)2 were u
We propose an ultra-thin glass film coated with graphene as a new kind of surrounding material which can greatly enhance spontaneous emission rate (SER) of dipo
伊马替尼( Imatinib,IM)是以bcr-abl融合蛋白为作用靶点的治疗慢性髓系白血病(CML)最有效的酪氨酸激酶抑制剂(TKI),但长期应用可使部分CML患者产生IM耐药性[1],特别是bcr-abl
采用自主开发的工艺加工技术和设计方法,直接将两个微波SiC MESFET管芯在管壳内部进行并联,实现了器件在S波段脉冲状态下(工作频率2GHz,脉冲宽度30μs,占空比10%)输出功率大
As an ionic conductive functional layer of intermediate temperature solid oxide fuel cells(ITSOFC), samarium-doped ceria(SDC)–Li Na SO4nano-composites were syn
在科学和技术的进步,社会经济的不断发展,人民生活水平的提高,互联网已经深入人们的日常生活,电子信息技术的重要技术支持人们生活正常运行,目前已进入大数据的时代网络信息。互联网使人们生活方便但也有一定的信息安全风险,如侵犯人们的隐私的行为越来越多。为了保护人民基本权利,要构建一个安全、稳定的网络环境。本文基于TCP/IP协议的网络安全问题进行了讨论和分析。
