近期，新疆、贵州等地省级农商行改制重组消息频传。而在河北衡水、沧州等地，市级统一法人农商行 改革试点也正悄然推进，整合后的县级法人机构，正化身为更强大平台的分支网络。这种"减量"的整 合，正成为全国农信改革浪潮的缩影，其根本目标在于"提质"。 在科技浪潮的推动下，这场改革已不仅仅是农信机构的整合，更关乎如何以数字技术为引擎，开启服 务"三农"的新征程。 放眼全国，多地农信系统改革方案获批或实施，新组建的省级农商行资产规模迅速攀升，"万亿银行"接 连亮相。其主要模式聚焦于"省级农商联合银行"与"统一法人省级农商银行"。 改革的动因，源于农信系统长期存在的"小散弱"格局——机构单体规模小、资本实力弱、抗风险能力不 足，制约了整体发展。曾有案例，某县级行社因资金调度困难，无法及时满足农民春耕贷款需求。这不 仅影响了农业生产，也削弱了金融支农的根基。 因此，改革旨在通过增强资本实力、系统化解历史包袱，提升农信机构的整体稳健性。而当下，大数 据、人工智能等技术正深刻重塑传统金融业态。 "数字重塑"绝非简单的业务线上化，而是以数据为纽带，重构农信系统的核心竞争力。 首先，数字技术有助于打破数据壁垒。过去，各县域机构数据往 ...

AI可以极大程度地解放生产力，尤其在科研领域，它可以让繁冗的数据分析等工作大幅提速，让科研 人员将更多精力投入到创造性环节，进而提高科研效率。但对于AI向普通生活的入侵，尤其对其经由 语言系统"侵蚀大脑"的趋势，则需保持批判性审视的态度。 我们每个人都应持有一份清醒和自觉，和AI保持一定距离，始终把它圈定在"工具角色"的范围之内。我 们可以善用它在检索和整合上的优长，甚至将其作为参考启发、润色校正的助手，但不能逾越"雷池"， 让其直接代笔成为"脑替"。 未来，AI势必会接手人类更多的琐碎事务，成为工作、生活的参与者，但不应成为"主导者"。具体到语 言应用上，我们不应向AI交出自己的"语言权"。让技术的归技术、文化的归文化，或许才是我们的正确 选择。 （文章来源：科技日报） AI的普及是迅速的，"开源"之后，AI生成的文本大量流入社会生活。无论是常用文书，还是社交平台、 网络电商的文本文案，文风都为之一变。 这是一种什么样的语言呢？人们一定很难忘记初见它时的惊讶：结构严谨，语法完美，逻辑流畅，辞采 斐然，术语翻飞，比喻排比迭出……但这种没有瑕疵的语言慢慢传递出一种冰冷的"工业味"：模式化、 套路化，如同一种新型 ...

Core Viewpoint - A groundbreaking research led by Professor Xu Hui from Heilongjiang University has successfully achieved efficient electroluminescence in insulating rare earth nanocrystals, transforming the concept of "insulating luminescence" from impossible to reality [1]. Group 1: Research Background - Professor Xu Hui began his academic journey in 2003, focusing on organic electroluminescent (OLED) materials, particularly rare earth complexes, which are seen as core materials for next-generation display technology due to their narrow emission bands and high color purity [2]. - Despite the potential, rare earth complexes faced two major challenges: poor stability and low electroluminescence efficiency. Xu addressed stability issues by utilizing phosphine oxide ligands, significantly enhancing the material's stability for industrial production [2]. Group 2: Research Development - After resolving stability issues, the electroluminescence efficiency remained below industrial standards. Xu shifted his focus to understanding the physical mechanisms of the luminescence process, leading to the development of red-emitting rare earth complexes that met international standards [3]. - In 2006, Xu joined Heilongjiang University, where he built a research lab from scratch, demonstrating resilience and innovation despite limited resources. His team achieved significant breakthroughs, including publications in prestigious journals [5]. Group 3: Innovative Approach - Xu's team explored rare earth nanocrystals, which possess superior luminescent properties but are inherently insulating, preventing charge entry. They proposed a novel concept of using ligands to create a "photoelectric bridge" to facilitate energy transfer [6]. - Over 14 years, the team tested over 200 materials to find suitable ligands, ultimately designing the optimal molecule CzPPOA, which efficiently transfers electrical energy to the insulating rare earth nanocrystals with a remarkable efficiency of 96.7% [6]. Group 4: Collaborative Efforts - The research involved deep collaboration with teams from the National Academy of Singapore and Tsinghua University, highlighting the importance of teamwork and strategic guidance in achieving scientific breakthroughs [7]. Group 5: Education and Mentorship - Xu emphasizes the importance of cultivating students' problem-solving abilities rather than merely imparting knowledge. His mentorship has led to the rapid development of students, some of whom have become key figures in the research team [8]. - Xu's approach fosters collaboration among students, encouraging them to engage with the broader scientific community, which is essential for achieving significant research outcomes [9].

近日，中国科学院大连化学物理研究所研究员李先锋团队在溴基多电子转移液流电池新体系研究方面取得了新进展。团队成功开发出一种新型溴基两电子转 移反应体系，实现了长寿命锌溴液流电池的概念验证及系统放大。相关成果发表在学术期刊《自然·能源》上。 溴基液流电池依赖于溴离子（Br-）与溴单质（Br2）的氧化还原反应，具有资源来源广、电极电势高以及溶解度高等优势。然而，在充电过程中产生的大量 Br2会对电池材料造成严重腐蚀，显著降低电池的循环寿命，并对电池材料的耐腐蚀性提出了更高的要求，进一步推高了电池成本。传统溴络合剂虽然在一 定程度上可以缓解腐蚀问题，但其形成的分相结构往往导致体系均匀性差，增加了系统复杂性。 为解决这一难题，团队开发出一种新型溴双电子转移反应路径。通过在溴电解液中引入连接吸电子基团的胺类化合物作为溴清除剂，他们发现电化学反应中 产生的Br可以转化为溴代胺类化合物，有效降低溶液中Br的浓度。与传统的单电子转移方法（Br到Br0）不同，该反应实现了从Br到Br（溴代胺类化合物） 的双电子转移，显著提高了电池的能量密度。同时超低的Br浓度大幅度降低了电解液腐蚀性，提高了电池寿命。 研究团队进一步将这一新反应 ...
