Grain & Oil Science and technology 2020年第1期3卷 18-24页

The aim of this study was to analyze the physicochemical and structural characteristics of the Venn components of wheat gliadin to provide theoretical basis of gliadin for processing in dough and Chinese steamed bread. Eight Venn components, Gli-8, Gli-9, Gli-10, Gli-11, Gli-12, Gli-13, Gli-14, and Gli-15, were extracted from wheat gliadin based on their solubility. The results of physicochemical characteristics showed that the differences in the contents, TDS,electrical conductivity, particle size and zeta potential of Venn components were significant, respectively. The content of Gli-15 in gliadin was the highest, and the content of Gli-9 was the lowest. The TDS value of Gli-9 was the highest(336.0), and the TDS value of Gli-15 was the lowest(52.0). The electrical conductivity of Gli-9 was the highest,which was 7.54 times the lowest value of Gli-11. The zeta potential of Gli-9 was -25.2 mV, and the zeta potential of the Gli-15 was -7.64 mV. However, the difference in the p H values was not significant. The results of uv spectrum and FTIR analysis showed that the secondary structures of the Venn components had significant differences. The results of the XRD patterns indicated that the Venn components might not be a single substance. The results of CLSM images implied that the molecular interactions among the components were varied. Hence, the results could provide research materials and basic data for deep processing and utilization of gliadin.

稀土(RE)微合金化是开发高品质模具钢的重要手段之一。采用稀土渣系结合电渣重熔实现H13钢铸锭的稀土添加,重点对比研究了稀土氧化铝渣系和氧化铝渣系所制备H13钢铸锭的成分、组织及夹杂物特征,揭示了稀土氧化铝渣系对于H13钢铸态组织的稀土改性作用及机制。结果表明,采用稀土氧化铝渣系或稀土氧化钙渣系均可制备稀土质量分数约0.01%的H13钢铸锭,并分别将S质量分数从电极(原料)的0.01%降低至铸锭的0.005%和0.002%。稀土氧化铝渣系的H13钢铸锭中晶界处有稀土La富集,晶内分布尺寸1~2μm的近球形稀土硫氧化物La_(2)O_(2)S(与基体具有4.7%的较低界面错配度)。相比氧化铝渣系,稀土氧化铝渣系将H13钢铸态组织的二次枝晶平均尺寸从109.6μm减少到84.9μm,液析碳化物和夹杂物平均尺寸从5.1μm减少到3.1μm,从而改善稀土H13钢铸态组织的均匀性。

有机无机杂化钙钛矿太阳能电池(PSCs)近几年吸引了众多的关注。目前,在反式平板异质结钙钛矿太阳能电池中,最普遍使用的电子传输层材料是富勒烯衍生物PCBM,但是由于其价格昂贵,将会影响钙钛矿太阳能电池的最终产业化。本文开发出一种新的低成本富勒烯衍生物N-甲基-2-戊基[60]富勒烯吡咯烷(NMPFP)来取代PCBM,用于反式钙钛矿太阳能电池的电子传输层。和PCBM电子传输层相比,NMPFP具有更快的电子传输速率。用NMPFP制作的钙钛矿太阳能电池几乎没有迟滞现象,取得了13.83%的光电转换效率,和PCBM电池性能相当。而且,由于NMPFP更强的疏水性,其电池的稳定性优于PCBM电池。本研究表明NMPFP是一种非常有前景的电子传输材料,用于反式平板钙钛矿太阳能电池,可以有效的取代PCBM。

The recent appearance of mobile application processor now plays an important role in the semiconductor industry. Additionally, there have been endless demands for small form factor, thin profile, outstanding thermal, mechanical properties and electrical performances in the field of IC packages for mobile application processors. MIS (Molded Interconnect Substrate) can provide ideal and this solution in the mobile industry as it contains multiple solutions for the complicated requirement of the IC packages for application processors. Based on the embedded pattern technology, this solution can provide high I/O count, fine pattern for small form factor, and stable flip chip mounting methods. Other advantages of this solution include stable properties required for high-frequency transmission and high thermal dissipation rate as it is only composed of copper and epoxy mold compound materials. These core techniques for MIS technology can be divided into below major concepts. First, Cu pillar electrolytic plating technology electrically connects the inner and the outer layers using photo-lithography method, instead of laser method. The shape of Cu pillar and the plating thickness tolerance control are the key parameters. Second, grinding technology is to precisely grind the plated Cu pillars and applied mold epoxy. And deposition of Cu layer on top of grinded mold surface can construct fine pattern traces.
