Although traditional Thai fried banana snack (‘Klui Break Taek’ in Thai) is one of the favourite and high value snacks, practically it has a short shelf life (i.e. 14 days) under ambient atmospheric conditions because of rancidity and low crispness. In the present work, active modified atmosphere packaging systems (Ac…
Graphite-like amorphous carbon film was fabricated by unbalanced magnetron sputtering technique.Raman spectroscopy,atomic force microscopy(AFM)and tribometer were subsequently used to investigate the microstructure and tribological properties of the resultant film.It is found that the deposited carbon film is dominate…
The table of contents image illustrates the strain-gradient effect on the optical-electronic properties in a bent ZnO microwire, with a much stronger red-shift on the outer tensile side than a blue-shift on the inner compressive side. The low temperature cathodoluminescence cross-sectional scanning spectra on the stra…
采用合金平衡组织结构分析法结合热分析,研究了Nb-Ni-Ti系L(βTi,Nb)+TiNi共晶相平衡.结果表明,随着温度的降低,处于液相L、(βTi,Nb)和TiNi相三相平衡时的(βTi,Nb)相中Ni含量(摩尔分数)几乎不变,约为3.5%;而Nb的摩尔分数逐渐降低,从1 050℃时的62.6%,降为1 000℃时的54.1%;但TiNi相的成分变化不大.L+(βTi,Nb)+TiNi三相区也随温度的降低逐渐远离Nb-TiNi连线.并且随着Nb的溶入,Ti2Ni相的熔化温度也得以提高.
We numerically studied optical radiation pressure effect on metallic thin film in a magnetic metamaterial under oblique incidence. The model system consists of an aluminum nanowire and a spatially separated homogeneous gold thin film. We found that for localized SPPs coupling electrons in the metallic film are pulled…
开窗是刚挠结合印制板实现挠性弯曲的关键工艺,主要有通窗和盲窗法,其中后者因过程可对挠性窗口区域起良好的保护作用等而广泛应用,但其生产过程存在等离子处理爆板风险.本文通过对压机真空度、刚板厚度、盲窗面积/周长比、开窗区域是否覆铜等因素的影响进行研究,具体分析了等离子过程产生爆板的原因,总结出了在真空压合的条件下,刚板厚度和开窗区域是否覆铜是影响生产板等离子处理爆板的主要因素,并提出了一种新型的改善方法——开窗区域去铜法,该方法可有效改善排气降低气压影响,为盲窗工艺的扩大应用提供参考.
System-on-Chip (SOC) is a microchip consisting of different components such as processor, memory and logic circuitry all on the same chip and for providing communication between these components on the chip Network-on-Chip (NOC) is required as the conventional interconnects are not suitable to fulfil the demands. The…
Based on the mechanism of spoof surface plasmon polaritions (spoof SPPs), we present a kind of microwave band pass fllter in both theory and experiment, which is realized by periodic subwavelength metallic Domino array. The transmission bandwidth of spoof SPPs is controllable by designing the geometric parameters of t…
We have used X-ray absorption fine structure method and molecular dynamics (MD) simulations to characterize atomic order in Cu-Zr metallic glasses (MGs) [1]. The microstructure of these MGs is described in terms of interconnected icosahedral-like clusters (superclusters) which are basic building units reproducing the…

A new class of dicarboxylic bola-shaped compounds 1-2, possessing phthalyl head groups and diol spacers are synthesized and characterized. Keeping phthalyl head group common for all two diester-dicarboxylic acids, the spacer moiety is systematically altered by three and eight carbon atoms in 1 and 2, respectively. The…
A trial to use a natural, safe and available inhibitor in reducing corrosion rate of brass in tap water was held, this inhibitor is bees honey. The conditions of experiment look like to that in cooling systems at least in a stage of it. The corrosion estimation was evaluated by using weight loss method with and withou…
In this paper we describe an implementation of a single-uid interface model in the ALE-AMR code to simulate surface tension eects. The model does not require explicit information on the physical state of the two phases. The only change to the existing uid equations is an additional term in the stress tensor. We show r…
The purpose of this investigation was to explore the technical aspects of fast bowling, specifically those technique factors that are related to release velocity. Release velocity of the ball is an important characteristic for any fast bowler as any increase in release velocity can increase the probability of dismissi…
The process of slow material fragmentation is studied when the diffusion approximation is applicable. Final distribution density of fragment sizes is calculated in the case of scale-homogeneity of subdivision mechanism
We report experimental results on efficient all-optical modulation of terahertz waves over a wide band from 0.2 to 1.5THz with a modulation depth of up to 99% by means of a graphene-on-silicon (GOS) modulator. We observed that the sensitivity of the GOS modulator to the incident power of the modulating laser beam was…
The aim of this work was to find the best processing technique for poly(L-lactide)/olive stone flour (PLLA/OSF) composites. Processing with horizontal single-screw extruder gave nonhomogenous composites and was abandoned. The composites prepared using vertical twinscrew compounder followed by injection moulding and Br…
