Hierarchically hollow nanostructures have been the focus of numerous studies due to their prominent physicochemical properties that differ significantly from bulk materials and their potential for extensive applications. We present a novel diatom-based scaffold for the synthesis of hierarchically biomorphic CeO2 with…
Thermal conductivity is a key parameter for thermal design and management of the electronic compo- nents in their passive cooling processes. In this work, thermal and electrical conductivities of six groups of binary Mg alloys (Mg-Al, Mg-Zn, Mg-Sn, Mg-Zr, Mg-Mn, and Mg- Ca) in as-cast, as-solution, and annealed states…
/BDSAK 是 1:1。稳定性常数在各种各样的温度被计算了，热力学的参数也从由使用 van’t Hoff 方程的稳定性常数的温度依赖是坚定的。结果显示有 BDSAK 的碘建筑群是稳定的热含量，但是熵使动摇。
The ultrafine Ce-based oxide nanoparticles with different element dopings(Zr,Y) were synthesized by the method of micropores-diffused coprecipitation(MDC) using ammonia solution as the precipitation agent.The activities of the catalysts for soot oxidation were evaluated by the temperature-programmed oxidation(TPO) rea…
The influence of C60 aggregation on time-resolved (TR) electron para- magnetic resonance (EPR) of C60 in the excited triplet state was investigated by multifrequency EPR techniques. Temperature-independent X-band (9.7 GHz) TR- EPR spectra were observed in a fresh toluene solution, while temperature-dependent ones were…
Ionic liquids have been the subject of study over the past several years and there are quite a few advantages to their use in charge storage devices such as extremely low volatility, high voltage window, and inherently high concentration of cations and anions for charge transport processes1-8. Several ionic liquids ar…
由与钯(Pd ) 装载的多孔的膜的偶氮的染料的催化没有水泡的加氢减小 nanoparticles 第一次被学习。装载的 Pd 的效果，染料集中和膜的复用重复被调查。在减小，而 pH 逐渐地升起了，染料集中减少了。装载的最佳的 Pd 被发现。催化的膜能被再使用超过 3 次。
The process of equal channel angular pressing(ECAP)of 7075 aluminium alloy is numerically simulated using a finite element software to predict the microstructure grain size.The method of the combining application of finite element simulation and experimental analysis is explored to investigate the variation of microst…
A volume-adjustable cavity of molding machine for polymer foaming was fabricated with renovation of an ordinary injection molding machine.Polypropylene(PP) composite foams were prepared by chemical foaming method via the volume-adjustable cavity of the molding machine.The decompressing and short shot processes in prep…
In this paper the influence of two different sizes of silica particles (micro-silica and nano-silica) was studied on mechanical properties of sulfur and sulfur composite. To improve the structural properties, sulfur was plasticized using dicyclopentadiene (DCPD) and methyl styrene (MSt). Plasticized sulfur composite w…
To prepare the porous NC-based （nitrocellulose-based） gun propellants, the batch foaming process of using supercritical CO2 as the physical blowing agent is used. The solubilities of CO2 in the single-base propellants and TEGDN （trimethyleneglycol dinitrate） propellants are measured by the gravimetric method, and SEM…
新 MnSiAlMoNb 导致转变的粘性钢被退火让不同持续时间调查划分 C 元素和微结构成分的体积部分变化的 intercritical 退火。直接试验性的证据证实由电子探查微量分析和 X 光线衍射在热处理期间在不同阶段划分 C 元素。precipitates 的分发也被调查。微观结构和调查的钢的机械性质被退火的 intercritical 影响，这被揭示时间。根据现在的实验，保留的奥氏体的体积部分和张力的力量的产品和有增加退火的 intercritical 的调查的钢减少的全部的延伸预定。1,103 MPa， 21.3% 的全部的延伸，和 23,493.9 MPa % 的力量韧性产品的高张力的力量能成功地在退火的 intercr…
ZnO sub-microspheres were synthesized via a new, simple, and one-step method by using zinc acetate dihydrate as a precursor and PEG200 as a solvent and modi- fier. The effect of temperature (160-210 C) on the crystal- lization, surface morphology, and luminescence properties of ZnO spheres was investigated using diffe…
Understanding the role of chemical burn addi- tives on modifying the toxic gaseous constituents and thermal behavior of reconstituted tobacco sheet (RTS) has recently taken center stage through a number of initiatives. In this current study, the effects of ammonium chloride (AC), ammonium sulfate, diammonium phosphate…
Calculations of the ElectroMagnetic(EM) response produced by a large horizontal loop placed over layered medium are rather complex because its integral expression contains the product of two Bessel functions and has a divergent term. In this paper, an improved fast Hankel and Gaver-Stehfest transforms are introduced t…
本地原子对称为在金属性的眼镜里理解机械、震动、动态的性质被调查并且讨论。本地五倍的对称在 Voronoi 镶嵌细工方法分析的 Voronoi 簇基于五边形的比率被定义到脸的全部的数字。塑料变丑喜欢与本地五倍的对称(LFFS ) 的更少的度在这些区域被开始并且与 LFFS 的更多的度向这个区域逐渐地宣传，这被发现。在另一方面，有 LFFS 的更少的度的本地结构作出贡献更多到软低频率的模式，并且这样所谓的波色子山峰，当那些在金属性的眼镜里在中等频率、高周波的模式与 LFFS 的更多的度参与更多时。在本地原子对称和结构的异质，机械异质，和玻璃转变之间的关系也被讨论。本地原子对称能为更好在非结晶的合金理解结构性质关系是在金属性的液体和眼镜…
Synergistic effect in network formation of nylon-6(PA6) nanocomposites containing one dimensional(1D) multi-walled carbon nanotubes(CNTs) and two dimensional(2D) layered double hydroxide(LDH) platelets on improving the mechanical properties has been studied. Mechanical tests show that, with incorporation of 1 wt% LDHs…
Conventional plating / coating techniques like hard-chrome plating suffer from a serious drawback of being environmentally non-friendly. As a result, advanced surface engineering techniques such as electro-less nickel coating, thermal spraying etc. are being increasingly used to replace these conventional surface prot…
