A broadband adjustable absorber operating in the terahertz (THz) range is presented based on a vanadium dioxide (VO2) multiple ring structure with certain gap design. The dynamic absorption regulation of realized by utilizing phase-change characteristics VO2, which easily affected external temperature. simulation results show that when temperature reaches 350 K, conductivity VO2 can reach 2 × 105 S/m, and obtain an efficiency over 90% from 3.01 THz to 7.27 THz. At this time, bandwidth 4.26...
A complex medical instrument exterior shell was chosen as a studying object to investigate the influence of relative low (<10 MPa) gas counter pressure process on microcellular injection molding process. The mould and related experiments were designed. under which melt can foam mainly considered improve surface quality molded parts without significantly prolonging production cycle. effects parameters quality, cell morphology, density studied. critical flow front effectively eliminate...
A novel and greatly simplified strategy was developed to fabricate high-permittivity dielectric nanocomposites. Interface structure, precursor rheology properties of the 0–3 BaTiO<sub>3</sub>/PVDF–hfp nanocomposite film were investigated.
Graphene has attracted much attention in biosensing applications due to its unique properties. In this paper, the monolayer graphene was grown by chemical vapor deposition (CVD) method. Using as electric channel, we have fabricated a field-effect transistor (G-FET) biosensor that can be used for label-free detection of RNA. Compared with conventional method, G-FET RNA run low cost, time-saving, and miniaturized measurement. The sensors show high performance achieve sensitivity 0.1 fM, which...
The stroke-averaged lift forces due to various vortex rings and their mutual interactions are studied using a flapping flight model (Rayner, J. Fluid Mech. , vol. 91, 1979, p. 697; Ellington, Phil. Trans. R. Soc. Lond. B, 305, 1984 b 115). system is decomposed into the wing plane (wing-linked) ring, loop closed by bound (arc-shaped) trailing wake (the shed previously). Using vorticity moment theory (Wu, AIAA 19, 1981, 432) we able identify roles of in production or reduction express as...
The microcellular injection-molded part usually consists of a foamed core region and two unfoamed skin layers on the cross section. This paper investigated formation process, mechanism structural characteristics in part. It is found that are formed processes namely “during filling” process “after process. shear flow fountain behaviors melt filling stage main controlling factors layer cooling solidification fundamental reason for Further studies has distinct regions, outer thin frozen which...
ABSTRACT In this article, we studied the cell forming process of microcellular injection‐molded parts. Using a modified injection molding machine equipped with Mucell ® SCF delivery system, microcellular‐foamed acrylonitrile–butadiene–styrene parts different shot sizes were molded. The structure on fractured surfaces along direction both vertical and parallel to melt flow in molded was examined. results showed that regular spherical cells region distorted ellipsoidal exist simultaneously....
A solar-blind UV photodetector is designed and fabricated based on a nanophotonic metal–oxide–semiconductor structure. large potential barrier of ∼3.8 eV at the metal/oxide interface enables detection by blocking electrons excited visible photons while allowing UV-excited hot to pass through. By selecting metal absorbers with high density states near Fermi level employing photon management in self-assembled pseudoperiodic nanostructures, we managed achieve ∼74% spectrally averaged absorption...
2D MoS2 attracts increasing attention for its application in flexible electronics and photonic devices. For material optoelectronic devices, the light absorption of molecularly thin absorber would be one key limiting factors device efficiency, conventional photon management techniques are not necessarily compatible with them. In this study, we show two semimetal composite nanostructures deposited on synergistic strain-induced band gap engineering: (1) pseudo-periodic Sn nanodots, (2)...
The development of tandem photovoltaics and photoelectrochemical solar cells requires new absorber materials with band gaps in the range ~1.5-2.3 eV, for use top cell paired a narrower-gap bottom cell. An outstanding challenge is finding suitable optoelectronic defect properties, good operational stability, synthesis conditions that preserve underlying device layers. This study demonstrates Zintl phosphide compound CaZn$_2$P$_2$ as compelling candidate semiconductor these applications. We...
Based on a Mach-Zehnder interferometer, we report the first observation of two different modes wire explosion for nanosized powder production in 5–30 kPa ambient gas, depending property material. For material with relatively high resistivity, such as titanium, more than one vapor burst was observed. While low copper, whole would explode totally within single burst.
The response of nuclear power plants (NPPs) to seismic events is affected by soil-structure interactions (SSI). In the present paper, a finite element (FE) model with transmitting boundaries used analyse SSI effect on NPP buildings subjected vertically incident excitation.
