周末专家河北行暨化学化工创新前沿与交叉融合学术活动：有机共轭自由基的合成和应用
有机共轭自由基又被称为奇交替芳烃，是体系中含有奇数个碳原子及π电子的稠环共轭结构。其未成对电子占据分子单占据轨道（SOMO），形成双线态电子基态。由于共轭骨架存在，其自旋将于整个分子离域，从而具有独特的反应活性和自组装性质，有作为新型反应试剂和新型有机光电及生物活性材料的潜力。然而稠环芳烃自由基往往具有较高的反应活性，这为其合成和分离带来挑战，同时阻碍了其作为功能材料的探索。我们课题组围绕“有机共轭自由基的合成/增稳策略与构性关系”核心科学问题，针对其种类单一、合成难度大、稳定性不足、构性关系不明等关键瓶颈，提出了全新分子设计与合成策略。通过调控自旋离域、拓扑结构及取代基位阻/电子效应，在提升自由基本征稳定性的同时，实现了其聚集结构、反应活性及物理性质的精准调控，并拓展了其在光电磁功能材料与生物活性分子领域的应用。

On Learning Dynamical Systems and Reservoir Computing
In various machine learning applications, dynamical systems naturally appear as both the target system as well as the model. In this talk, we discuss how principles from dynamical systems enter learning considerations and explanations. We begin by reviewing essentials from dynamical systems theory and build towards synchronization phenomena in non-autonomous systems. Notions such as echo states, state forgetting, and fading memory will be rigorously linked. Reservoir computers will accompany us as an important class of examples. Finally, we will discuss extensions to the setting of learning distributions of stochastic processes instead of deterministic dynamics.

beat365英国官网科技大讲堂之院士论坛——Semiconductor Design for Photoelectrochemical Energy Conversion
Semiconductor nanomaterials hold the keys for efficient solar energy harvesting and conversion processes like photocatalysis and photoelectrochemical reactions. In this talk, we will give a brief overview on our recent progress in designing semiconductor nanomaterials for photoelectrochemical energy conversion including solar hydrogen generation and low-cost solar cells. In more details, we have been focusing on a few aspects; 1) artificial photosynthesis reaction mechanism, light harvesting, charge transfer and surface reaction engineering of low-cost semiconductors for solar driven hydrogen and valuable chemical production; 2) the working mechanism and stability improvement of perovskite quantum dots and lead-free tin-based perovskite solar cells; 3). The design of ultra-stable perovskite-MOF composites with improved light emitting performance and photocatalysis. The resultant material systems exhibited efficient photocatalytic performance for value-added chemical production and improved power conversion efficiency in solar cells, which underpin sustainable development of solar energy conversion technologies towards carbon neuralization.

文苑大讲堂2026年第43讲： 词义认识的演进与词义概念的再界定
什么是词义？历来众说纷纭，莫衷一是。不仅在理论上令人困惑，而且在实践中遇到很多困难，有必要深化相关研究。回顾词义研究史可知，虽然定义差异明显，但认识在不断深化，而且体现出一定的内在演进逻辑。基于词义的特性和相关研究，我们提出：词义是一定的语音形式所承载的由一定语义内容和功能特征构成的复合语言信息。
