(接上期)3.2 橡胶防护 石油蜡在橡胶制品中用作物理防老剂已有很久的历史,这是因为石油蜡能迁移到橡胶表面形成蜡膜,起到屏障臭氧、延缓橡胶臭氧氧化的作用。 我国从20世纪8
作为ATP再生技术的应用延伸,该专题以卡拉胶-魔芋多糖复配胶为载体,将酵母固定化,应用于生物合成CTP,取得了较好效果.酵母可反复使用十余次,催化反应后易于与反应溶液分离,并
Optical gains of type-Ⅱ InGaAs/GaAsBi quantum wells (QWs) with W,N,and M shapes are analyzed theoretically for near-infrared laser applications.The bandgap and
Dipole coupled nanomagnets controlled by the static Zeeman field can form various magnetic logic interconnects.However,the coer wire interconnect is often unrel
We present a high-pressure study of van der Waals ferromagnetic metal Fe3GeTe2 through electrical transport and Raman scattering measurements in diamond anvil c
A new memristor (MR) emulator is designed by making use of only three current-feedback operational amplifiers,one varactor diode,one capacitor and five resistor
Layered black phosphorus (BP) has recently emerged as a promising semiconductor because of its tunable band gap,high carrier mobility and strongly in-plane anis
We propose and investigate a novel metal/SiO2/Si3N4/SiO2/SiGe charge trapping flash memory structure (named as MONOS),utilizing SiGe as the buried channel.The f
