Haynaldia villosa （L.） Schur （syn. Dasypyrurn villosum （L.） Can- dargy）（2n - 14, genome VV）, a wild relative of wheat, is an impor- tant gene pool for improving wheat quality and disease resistance. Several genes found in H. villosa have been transferred into wheat to improve wheat resistance by the development of alien transloca- tion lines. The seed storage protein loci on chromosome 1V contribute to grain quality （Zhang et al., 2014）.

四川三台县云台观创建于南宋,明代以"西岳云台"之誉与"武当太和"齐名,受到来自蜀王府和明朝廷的护持。历代蜀王均出资大力修建云台观,明万历二十七年与四十四年,明神宗两次赏赐《道藏》到云台观供奉。建国后这两部《道藏》分别被收藏于四川省图书馆与四川大学图书馆。本文基于对两部明代《道藏》的考察,分析两部《道藏》流转、版式、存本等重要内容,并对其中版式和图文进行辨析,以期推进对现存古本《道藏》的研究。

三台县云台观为北方真武大帝道场,也是明代四川蜀藩王府主要修醮之所。通过对云台观纪念真武大帝诞辰而举行“祖师会”的宗教社会学考察,可以看到道教真武信仰在四川地方社会中的广泛流布与持续影响。民间传说中真武大帝所具有的降福、禳灾、护民、降雨、护生等神性功能满足了信众的多方需求,体现出道教在地方社会信众中鲜明的信仰特征。“祖师会”所体现出的时间上的集中性与态势上的群体性,以及在不同信众的性别与年龄上的分布特点,也为研究地域宗教文化的传播以及现代道教在乡土社会中的发展特点提供重要参考。

选择性激光烧结(SLS)工艺中回收的尼龙(PA)12粉末(旧粉)的熔体流动性显著下降,严重影响旧粉的回收利用。研究了PA12旧粉和新粉的性能差异,然后分别以超支化树脂Hyper HPN202,Hyper C100和Hyper C181作为流变改性剂,采用机械共混法对PA12旧粉进行增塑改性,考察了各流变改性剂用量对其熔体流动性能、力学性能以及热性能等的影响。结果表明,Hyper HPN202,Hyper C100和Hyper C181均能有效改善PA12旧粉的熔体流动性,PA12旧粉的熔体流动速率(MFR)随着流变改性剂用量的增加而增大。Hyper HPN202的改善效果最佳,当其添加质量分数为1%时,PA12旧粉的MFR增加196.5%,拉伸强度较未添加时有些许增加,弯曲弹性模量和冲击强度较未添加时基本一致,维卡软化温度提高3.9%。

Crystallographic defects in noble metal nanocrystals are recognized as highly active catalytic sites, significantly enhancing activities in many important reactions. Despite their importance, synthesizing noble metal nanocrystals with a high density of defects poses a considerable synthetic challenge. Here, we present a novel lattice mismatch-induced formation mechanism to create high-density defects in noble metal nanocrystals. This approach takes advantage of lattice mismatch to enable nonepitaxial nucleation and growth of a noble metal on a foreign metal substrate, forming abundant noble metal crystallites with random lattice orientations not dictated by the substrate lattice. As these crystallites grow extensively, they merge, forming numerous grain boundaries and yielding defect-rich noble metal nanocrystals. Defect-rich alloy nanocrystals can also be synthesized through a subsequent vacancy-diffusion alloying process. We take defective PdCu alloy nanocages as an example and demonstrate the effectiveness of crystallographic defects in enhancing catalytic performance of noble metal *** nanocages exhibit superior activity in the electrocatalytic formic acid oxidation reaction, which is 1.6 times greater than their defect-free counterparts. Our strategy offers a new avenue for creating defect-rich noble metal nanocrystals as highly efficient catalysts for a wide array of catalytic applications.
