Micrometer sized multi-hollow spheres of epoxy resin were prepared by a physical method so-called phase inversion emulsification technique. The formation mechanism the titled was studied incomplete inversion. requisite for that irreversible coalescence among water droplets under shear action before point existed. This process could be facilitated lower emulsifier concentration and higher temperature. Moreover, theoretical explanation presented.
It is the first time that cadmium sulfide (CdS) nanorods have been fabricated on silicon (Si) pyramid surface by hydrothermal reaction method. In our work, Si morphology able to increase adhesion between CdS seed layer and wafer. Hence, it critical for grow successfully. During fabrication process, glutathione used as complexing agent formation of nanorods. By continuously adjusting experimental conditions, thickness layer, concentration glutathione, temperature reaction, optimal condition...
A set of oxidized polyacrylonitrile materials different surface situations were employed to examine how the dispersed particles properties influence electrorheological (ER) response. The shear stresses these ER fluids found peak for tension and polarity particles, which could be qualitatively understood with our recent finding that large dielectric loss, along constant, are argued good performance. Our findings have direct implication effect would most likely improved by means certain...
Atomic layer deposition is a key technique for preparing large area uniformity, three-dimensional conformal, and ultrathin films due to its sequential self-limiting saturated chemisorption properties. Electric fields of varying magnitudes directions were applied on Si, Al2O3, Au, Ni substrates in Pt plasma enhanced atomic processes. Studying the influences electric initial nucleation growth different helps understand dynamic knowledge underlying physical mechanisms so as obtain ultrathin,...
The nano-focusing performance of adiabatically designed Cartesian oval refocusing lenses is compared with other well known compound refractive parabolic profiles (both simple concave and kinoform types). Using beam propagation method (BPM) simulation, it shown that our design based on does significantly improve the focusing properties to lens designs, e.g. (AFLs), which doesn't take into account effect. This points importance optimizing complex in improving performance.
Abstract Tin dioxide (SnO 2 ) film is fabricated on the Silicon (Si) nanopillars surface with more than 5 aspect ratio via direct current (DC) magnetron sputtering for first time. Form XRD curves, SnO become multi‐crystalline after annealing at 750 °C hours, and substrates have no influence crystallization of film. For morphology, polished Si becomes from planar to plicated annealing, while there morphology change surface, which proves that suitable heat stress release during process. After...
Atomic layer deposition is a powerful technique for achieving atomic-level control in the of thin films and nanoparticles. The ultrathin noble metal can be applied many functional devices, but it challenge to obtain such since island growth mode generally happens instead mode. In this work, nucleation platinum on Si, Al2O3, Au, Ni substrates were studied using (MeCp)PtMe3 O2 plasma as precursor co-reactant, respectively. evolution Pt coverage different surfaces was observed discussed based...
The dielectric and electrorheological measurements of anhydrous ER fluids based upon oxidized polyacrylonitrile zeolite under AC electric field are described It was found that the yield strength not only determined by constant suspensions, but also loss. formulation on Wagner model, which describes polarization heterogeneous dielectrics, employed to predict stress as a function frequency. good agreement between experimental theoretical predictions indicated conductivity dispersed particle...
