A finite element method is applied to study the coupling of a single photon emitter in nanodiamond to surface plasmons of a silver nanowire. Sensitivity of this system to different parameters is explored. Novel applications for the coupled system are proposed.
In this work, natural pulverized locust beans hull exhibited high sorption capacity, four influence conditions studied at 30±2 0 C; the suspensions shaken at constant 130 rpm and analyzed with absorption spectrophotometer (AAS; Perkin-Elmer model Analyst 2000). Maximum equilibrium mg/g sorption attained within 30mins…
A new kind of flexible carbon nanotubes composite conductive paper were studied. Using pulp fibers as carrier whisker CNTs as conductive agent,the suspension were prepared by high-speed shearing in water. The suspension homogeneous precipitation formed interwaoven fiber mat by vacuum filtration.The final carbon nanotu…
Z-Pinch Inertial confinement fusion is a competitive candidate for future energy solution. A fusion-fission hybrid driven by Z-Pinch can be used to transmute transuranic elements from spent fuels of reactors efficiently. Analysis and numerical simulation of blanket neutronics of In-Zinerater, which is a fusionfission…
The sustainability benefits that remanufacturing concept brings about has called upon the need to further develop a sound understanding behind this technology. In this presented study, the primary focus is to investigate the detrimental effects of the clad layer on the fatigue performance of the laser cladded AISI 434…
Energy shaping technology could be used to reduce artifact error and increase nondestructive testing accuracy.How to produce required spectrum is a key issue.This article proposes spectrums whose peak energy are 3 MeV,6 MeV and 12 MeV especially as required spectrum and discusses calculation method for energy shaping.…
Strip deviation of Looper is a common phenomenon of continuous production line, Deviation will not only cause strip defects, reduce the yield but also affect the unit production capacity, and even cause damage to equipment. There are many factors causing the strip, such as process parameters, materials, equipment or o…
Comparative pilot refining trials with Norway spruce chips were conducted in order to gain a better understanding of the principal mechanisms on fibre level for achieving radical energy reduction i ...
The swelling behavior of natural rubber was investigated using the immersion and weighing technique to verify the transport mechanism and property of hydrocarbon solvent,which is ready for the study on the compatibility of endothermic hydrocarbon fuel and rubber.Natural rubber was vulcanized by sulfur vulcanization sy…
Rejlers has been requested by JRMekan to reconstruct a material container used by Boliden Rönnskär. The function of the material container is to store and transport various materials. The problem with today’s version of the material container is that it is not economically sustainable to manufacture. The reason for th…
本文采用荷电低压撞击器（ELPI）,通过对二级稀释系统采样对某电厂220 MW煤粉锅炉PM2.5的浓度排放特性进行了研究.研究结果显示,煤粉锅炉所产生烟气中PM2.5粒数浓度呈较明显的双峰分布,小颗粒峰值一般在0.12 μm或0.07 μm,较大颗粒峰值一般在0.76 μm,PM2.5粒数浓度一般为几百万粒/cm3,主要取决于由气化凝结机理形成的细模态颗粒物PM0.38,PM2.5质量浓度呈单峰分布,一般为几百mg/m3,其质量浓度主要取决于由中间模态颗粒物PM0.38～2.5;采用覆膜滤料的布袋除尘器和电袋联合除尘器对PM2.5具有较好的除尘效果,二电场电袋复合除尘器出口烟气中PM2.5最小可达200μg/m3,粒数浓度在几万粒…
