Third-order active-RC complex filter with automatic frequency tuning for ZigBee transceiver applicationsLI Di(李迪)1, JING Zhan(井站)1, YANG Yin-tang(杨银堂)1, WU Xiao-feng(吴笑峰)2, SHI Zuo-chen(石佐辰)1, LIU...)Abstract:A 3rd-order Butterworth active-RC complex band-pass filter was presented for ZigBee (IEEE802.15.4) transceiver applications. The filter adopted cascaded complex pole stages to realize the 3......
Modeling infrared radiative properties of nanoscale metallic complex slit arraysWANG Ai-hua(王爱华)1, NIU Yi-hong(牛义红)1, CHEN Yu-bin(陈玉彬)2(1. School of Materials and Metallurgy, Northeastern University... are also comprehensively studied. When multiple slit types coexist in an array (complex slits), a wide-band transmittance or absorptance enhancement is feasible by merging spectral peaks contributed......
La2Ce2O7 supported ruthenium as a robust catalyst for ammonia synthesisWenfeng Han,Zhi Li,Huazhang LiuInstitute of Industrial Catalysis, Zhejiang University of Technology摘 要:ammonia synthesis under conditions similar with industry. With La2Ce2O7 being calcinated at 700 or 800℃, the experimental results indicate that the Ru/La2Ce2O7 catalyst exhibits much higher......
