Recent years have witnessed the transformative impact from the integration of artificial intelligence with organic and polymer synthesis. This synergy offers innovative and intelligent solutions to a range of classic problems in synthetic chemistry. These exciting advancements include the prediction of molecular property, multi-step retrosynthetic pathway planning, elucidation of the structure-performance relationship of single-step transformation, establishment of the quantitative linkage between polymer structures and their functions, design and optimization of polymerization process, prediction of the structure and sequence of biological macromolecules, as well as automated and intelligent synthesis platforms. Chemists can now explore synthetic chemistry with unprecedented precision and efficiency, creating novel reactions, catalysts, and polymer materials under the datadriven paradigm. Despite these thrilling developments, the field of artificial intelligence(AI) synthetic chemistry is still in its infancy, facing challenges and limitations in terms of data openness, model interpretability, as well as software and hardware support. This review aims to provide an overview of the current progress, key challenges, and future development suggestions in the interdisciplinary field between AI and synthetic chemistry. It is hoped that this overview will offer readers a comprehensive understanding of this emerging field, inspiring and promoting further scientific research and development.

Journal of Semiconductors 2024年第2期45卷 7-9页

作者： Chengcheng Xie bin zhang Menglan Lv Liming Ding Engineering Research Center for Energy Conversion and Storage Technology of Guizhou School of Chemistry and Chemical EngineeringGuizhou UniversityGuiyang 550025China Center for Excellence in Nanoscience(CAS) Key Laboratory of Nanosystem and Hierarchical Fabrication(CAS)National Center for Nanoscience and TechnologyBeijing 100190China

The power conversion efficiency(PCE)for single-junction organic solar cells(OSCs),wherein the photoactive layer is a typical bulk-heterojunction containing donor and acceptor materials,has surpassed 19%[1−4].The advance is ascribed to the development of Y-series non-fullerene acceptors(NFAs)[5,6]and polymer donors[7−13],and the refined control of the blend film morphology.

宋杂剧首服“诨裹”的形制与流行原因

艺术设计研究 2024年第1期 61-67页

作者：张彬西安工程大学服装与艺术设计学院

首服“诨裹”最早出现并流行于宋代,是一种经过杂剧艺人夸张、变形处理后,带有滑稽色彩的头巾,也是副末或副净表演时使用的一种首服,与宋杂剧滑稽调笑的表演形式和角色属性有关。本文从物质文化研究角度出发,通过文献与文物的相互印证,... 详细信息

首服“诨裹”最早出现并流行于宋代,是一种经过杂剧艺人夸张、变形处理后,带有滑稽色彩的头巾,也是副末或副净表演时使用的一种首服,与宋杂剧滑稽调笑的表演形式和角色属性有关。本文从物质文化研究角度出发,通过文献与文物的相互印证,全面系统地对其进行了考察。研究表明:宋杂剧艺人首服“诨裹”的主要形制可以归纳为三种类型,并与宋代乐舞艺人首服缠头的形制不同,具有一定的特殊性;其流行原因与宋杂剧表演形式和角色扮演的需要密切相关;它是在宋人日常生活首服基础上加工创造出的“新首服”。宋杂剧艺人的“诨裹”样式,为后世元明杂剧首服的发展提供了借鉴与创新基础。

引言画扇具有实用和观赏的双重功能,宋代画扇以团扇形式存世,被裱成册页或卷轴,保留了观赏性,而失去了实用性。失去了原有的功能和语境。扇画又被美术史学者当成独立的绘画作品进行讨论,把它们放到同卷轴画相似的状况来关注。画扇作为单纯的绘画被当代观众欣赏或被学者进行艺术史书写。明代的宫廷画扇的境遇与此类似。明代是折扇流行的时期,本文试图将画扇放到宫廷赐扇的活动中和民间日常使用中,来考察画扇的功能以及它们连接宫廷和民间的特殊作用。一、韩雍与林良明代文官韩雍(1422-1478)于成化八年(1472)端午节在广州城与回乡探亲的宫廷画家林良(1413?-1488?)有过一次聚会。当时韩雍为左副都御史,提督两广军务,已经平定了大藤峡的瑶民事变。这次聚会的地点安排在总督行台的喜雨堂中,由韩雍宴请林良。

我国刑事法律援助的立法和司法现状显示法援辩护人际信赖并不乐观。基于制度增修形成的制度信任旁落了法援辩护人际信赖,法援辩护权能短缺损害了法援辩护人际信赖,辩护冲突危及了法援辩护人际信赖。但是,法援辩护人际信赖具有正当性,契合法援辩护之委托关系的内在要求、有助于推动法援辩护过程有效性、有利于实现法援律师忠实义务。通过转变法律援助机构的指派范式、确立被追诉人的不完全选任权以及强化法援律师的辩护质量的方式,建立、增进、稳固法援辩护人际信赖,促进我国刑事法律援助制度的良性运作。

Atomic nonlinear interferometry has wide applications in quantum metrology and quantum information *** we propose a nonlinear time-reversal interferometry scheme with high robustness and metrological gain based on the spin squeezing generated by arbitrary quadratic collective-spin interaction,which could be described by the Lipkin–Meshkov–Glick(LMG)*** optimize the squeezing process,encoding process,and anti-squeezing process,finding that the two particular cases of the LMG model,one-axis twisting and two-axis twisting outperform in robustness and precision,***,we propose a Floquet driving method to realize equivalent time reverse in the atomic system,which leads to high performance in precision,robustness,and *** study sets a benchmark for achieving high precision and high robustness in atomic nonlinear interferometry.
