herein, a low-cost, biodegradable, and high-performance microwave shielding graphite/starch material was fabricated via constructing a cation-π interaction between ammonium ions and graphite. The graphite flakes and starch were firstly mixed with distilled water containing ammonium hydroxide to form graphite/starch slurry under an ultrasonic assistant. The cation-π interaction could improve delamination degree and dispersion of graphite in starch matrix. The slurry was first used as a coating material on the surface of wood and paper to develop shielding packages. The effect of coating thickness and coating layers on EM shielding property of the materials was investigated. Second, the composites with a high orientation of graphite were fabricated by compression at high pressures. The electrical conductivity and EM shielding effectiveness(SET) of the materials were greatly enhanced by construction of cation-πinteraction and orientation of graphite. Specifically, the EM SETvalues increased from 56.9 to 66.8 d B for the composites with 50 wt.% graphite and 2.0 mm in thickness by constructing cation-π interaction. The EM SETvalues raised from 17.4 to 66.8 d B via the graphite orientation in the materials with the same components and thickness. The shielding mechanism of the compressed composites with orientation dispersion of graphite was also discussed in comparison to the coating layer with random dispersion of graphite.

The activity and selectivity of some diamine iron complexes were analyzed. The influence of phosphorous-oxygen chelates on the catalytic activity and selectivity of these diamine iron catalysts in ethylene oligomerization was presented. Experimental results showed that precatalysts exhibited moderate activities for the oligomerization reaction with high selectivities for low carbon C4 and C10 olefins. These selectivities were attributed to high reaction temperatures and accessible metal centers.

本研究对兄弟姐妹数量与青少年成长之间的关系进行了全面的理论探讨,并利用2010—2018年中国家庭追踪调查数据,为识别兄弟姐妹对青少年认知能力和主观幸福感的影响提供了微观证据。实证研究结果表明:拥有1个兄弟姐妹对青少年的主观幸福感有积极影响,这种影响效应随年龄增长而加强,并且在成年后依旧保持稳定;拥有兄弟姐妹可能对青少年的数学类认知能力产生负向影响,这种影响主要体现在较低学段样本中,并随年龄增长逐渐消失。本研究为父母制定生育决策时更有效地开展成本收益分析提供了支持,也为缓解养育焦虑、完善生育政策以及促进人口可持续发展提供了政策启示。
