Metastable seed-cry.tals: epitaxial growth of branched-array.organic heterostructure nanowires

Tunable light–matter interactions are exhibited by.organic low-dimensional cry.tals, making these cry.tals a promising platform for organic photonics. However, the precise sy.thesis of organic low-dimensional cry.tals remains challenging due to the stochastic nature of molecular nucleation processes. Herein, the directed nucleation process is driven by.the introduction of metastable seed-cry.tals as the trunk, which ultimately.leads to branched-array.organic heterostructures. The successful formation of organic heterostructures with high-density.branched array. is attributed to the highest attachment energy.(Eatt（023）=-104.25 kcal mol-1) of the exposed （023） cry.tal plane during the seed-cry.tal growth route. Significantly. these as-prepared heterostructures inherently.have an ultralow lattice mismatch ratio η of 0.7%between trunk and branch, which contributes to the multi-channel photon transportation. Therefore, this work provides valuable insights into a versatile sy.thetic strategy.for accessing low-dimensional heterostructures for integrated optoelectronics.

地震等灾害的突发性和破坏性导致大量且多样的避难需求,但灾后物资往往不能快速有效地送达,容易出现应急资源供需匹配低效的问题。综合考虑分层避难需求下应急避难场所选址、人员疏散和物资分配等三个重要决策,基于灾后三层应急避难结构框架,本文构建了具有递归机制的应急避难网络,包括避难灾民和不同种类物资需求数量预测、应急避难场所选址和人员疏散以及物资分配;还提出了混合决策方法,包括模糊聚类和多目标规划模型,旨在优化应急避难场所位置和开放数量、灾民疏散距离以及物资满足率。以四川省成都市为例,本文分析了灾民疏散和安置过程,结果表明本文所提方法能公平快速地解决灾后初期应急避难场所选址、灾民疏散和物资分配问题,确保应急避难行动有序高效地进行。

Reaction mechanisms between molten CaF2-based slags and molten 9CrMoCoB steel

引用

International Journal of Minerals,Metallurgy.and Materials 2020年第5期27卷 611-619页

作者： Lei-zhen Peng Zhou-hua Jiang Xin geng School of Metallurgy Northeastern UniversityShenyang 110819China

Investigating the reaction mechanism between slag and 9CrMoCoB steel is important to develop the proper slag and produce qualified ingots in the electroslag remelting(ESR) process. Equilibrium reaction experiments between molten 9CrMoCoB steel and the slags of 55 wt%CaF2–20 wt%CaO–3 wt%MgO–22 wt%Al2O3–xwt%B2O3(x = 0.0, 0.5, 1.0, 1.5, 2.0, 3.0) were conducted. The reaction mechanisms between molten 9 CrMoCoB steel and the slags with different B2O3 contents were deduced based on the composition of the steel and slag samples at different reaction times. Results show that B content in the steel can be controlled within the target range when the B2O3 content is 0.5 wt% and the FeO content ranges from 0.18 wt% to 0.22 wt% in the slag. When the B2O3 content is ≥1 wt%, the reaction between Si and B2O3 leads to the increase of the B content of steel. The additions of SiO2 and B2O3 to the slag should accord to the mass ratio of [B]/[Si] in the electrode, and SiO2 addition inhibits the reaction between Si and Al2O3.

Novel Hash Function Based on Coupled Chaotic Map Lattices

引用

Chinese Journal of Electronics 2014年第4期23卷 836-841页

作者： zhen Ping ZHAO geng MIN Lequan LI Xiaodong School of Automation and Electrical Engineering University of Science and Technology Beijing Beijing Electronic Science and Technology.Institute School of Mathematics and Phy.ics University of Science and Technology Beijing

Hash function has been widely.used in cry.tographic field. This paper proposes a Hash function based on complexly.Coupled chaotic map latices(CCML).It is equipped with new features of parallel and flexible processing. Parallelism indicates that the algorithm can reach high level of efficiency.and speed. Flexibility.means the length of Hash function and message block processed each time can be easily.changed to adapt to practical demand. Experimental results show that the Hash function is one-way. with high plaintext sensitivity. as well as its strong capability.for confusion and diffusion, and collision resistance. In comparison with MD5 and another Hash function based on chaos, the proposed Hash function shows good performance.
