Efficient cathode interfacial layers (CILs) are becoming essential elements for organic solar cells (OSCs). However, the absorption of commonly used materials (CIMs) is either too weak or overlaps much with that photoactive materials, hindering their contribution to light absorption. In this work, we demonstrate construction highly efficient CIMs based on 2,7-di-tert-butyl-4,5,9,10-pyrene diimide (t-PyDI) framework. By introducing amino, amino N-oxide and quaternary ammonium bromide as...
Structural centrality metrics of the networks are important features to identify central nodes or links, assess network vulnerability against removal and manage control traffic reduce congestion. Classic graph-based not effective in dynamic space satellite due changing connectivity they cannot effectively capture temporal properties. In this paper, we employ a new technique called time-varying graphs (TVGs) express concepts definitions propose several order account for networks. To calculate...
Mechanochemistry studies the effect of mechanical force on chemical bonds, bringing opportunities for synthesizing alloys, ceramics, organics, polymers, and biomaterials. A vital issue applying macro-scale to manipulate crystal structures is finding ways precisely adjust directions break micro-scale target bonds. Inspired by a common technique driving wedge into wood make chopping much easier, wedging strategy splitting three-dimensional structured crystalline frameworks then converting them...

Abstract Efficient cathode interfacial layers (CILs) are becoming essential elements for organic solar cells (OSCs). However, the absorption of commonly used materials (CIMs) is either too weak or overlaps much with that photoactive materials, hindering their contribution to light absorption. In this work, we demonstrate construction highly efficient CIMs based on 2,7‐di‐ tert ‐butyl‐4,5,9,10‐pyrene diimide (t‐PyDI) framework. By introducing amino, amino N‐oxide and quaternary ammonium...
Currently, the development of urban slow traffic information services is lagging. Numerous issues, such as lack and deficient dissemination, restrict technical economic development, systems. So it critical crucial to develop for pedestrian bicycle In this paper, a smartphone-based platform proposed provide customized ubiquitously walking cycling commuters with various characteristics demands. The can value-added like smart tour by cooperating mobile operators, or promote national...
随着时代的迅速发展与信息技术的广泛渗透，数字技术赋能高校思政课具有丰富的价值意蕴，其能够创新教育模式，提升教学效果；深化师生互动，增强情感交流；优化教育生态，促进教育公平。但在实际运用中还面临着混淆教育内容与数字技术主次地位、教育者数字技术运用素养有待提高和高校思政课数字化协同育人机制尚未健全的现实困境。因此，在教学内容方面，应把握基本原则，将数字技术融入“大思政”育人格局；在教育者方面，应破除教师的技术应用障碍，提升思政课教师数字化素养；在高校与社会方面，应强化数字教育顶层设计，构建多元协同的育人模式。通过这些举措将进一步优化高校思政课教学实践，推动高校思政课教育现代化。
在新时代背景下，高校应积极加强马克思主义理论学科建设，充分发挥高校思政课教学的思想引领和价值塑造功能。马克思主义理论学科支撑高校思政课教学具有重要意义，其不仅有利于为思政课教学提供坚实的理论基础，还有利于为高校思政课提供人才支撑，并发挥马克思主义理论对社会意识形态的引领作用。高校应坚持姓“马”姓“共”、立德树人和把握问题导向的基本原则，通过辨析社会思潮、加强马克思主义理论学科建设、推动高校思政课教学改革、构建马克思主义理论学科与思政课教学科研一体化团队和建设马克思主义理论学科和思政课程双向支撑机制的一系列举措推动思政课教学质量和效果得以提升，为培养社会主义建设者和接班人贡献力量。
Wireless network's traffic capacity is one of the most important measurements network performance. In a vulnerable environment, attacks for components can cause degradation and lead to increasing congestion overall performance degradation. this paper, we propose an effective protection resources allocation scheme which allocates limited nodes based on assessment vulnerability components. This proves be best strategy in respect enhancing quantity capacity. The simulation results show that...
Chatter causes great damage to the machining process, and selection of appropriate process parameters through chatter stability analysis is significance for achieving chatter-free machining. This article proposes a milling method based on barycentric rational interpolation differential quadrature (DQM). The dynamics considering regeneration effect first modelled as time-delay equation (DDE). When adjacent pitch angles cutter are symmetric, dynamic contains single time delay. Otherwise, when...
