明日主题前瞻 点评:国泰海通表示,2024年以来稀土价格逐步筑底,国内指标配额放缓基调延续,海外稀土开发预期发酵但实际进度或不及预期,而需求端新能源汽车、 家电、风电等领域维持需求基本盘,人形机器人形成远期向上期权,供需反转大幕已徐徐拉开。稀土作为国内战略品种,有望迎来盈利、估值双击。 5、金融科技 | 6月24日举办"数据要素x"系列第二场新闻发布会,中国人民银行科技司副司长周祥昆在会上详细介绍了中国人民银行在《"数据要素x"三年行 动计划(2024-2026年)》发布以来的工作成效。并表示,中国人民银行下一步将研究制定新阶段金融科技发展规划,出台深化运用金融科技推动金融数字化智 能化转型的政策文件,会同国家数据局开展"数据要素x"试点,引导金融机构在安全合规前提下,发挥金融海量数据和多元应用场景优势,增强数据基础能 力和底座支撑,激活做好金融"五篇大文章"的数据引擎。 1、星闪 | 据中证报报道,近日,国际星闪联盟秘书长曾国松在华为开发者大会上表示,在标准化方面,星闪标准引领产业生态发展。星闪SLE国家标准预计 今年正式发布;采用星闪SLB技术的《营运车辆全景环视系统技术要求和试验方法》(商用车360度环 ...
我科研团队成功合成稀土三重键化合物

稀土是重要战略资源,其化学键性质直接影响稀土化合物的特性、功能和技术应用。近日,我国科研团 队成功实现了长期以来被视作"科研禁区"的稀土三重键化合物的制备,打破了对稀土元素成键能力的传 统认知,为稀土化学键理论的发展提供了新的实验依据和理论支撑。相关研究成果已于近日发表在《自 然·化学》杂志上。 稀土元素包括钪、钇和15种镧系元素,电子结构呈现出极为复杂、特殊且多样的特点。在稀土化合物 中,化学键主要以基于静电作用的离子键形式存在,由于4f轨道的收缩效应和5d轨道的较高能量,稀土 元素形成共价键,特别是双重键和三重键的能力十分有限。也正因为这一特性,长久以来,制备出含双 重键的镧系稀土化合物已是极为罕见,制备其三重键化合物更是被认为"不可能"。 成功构建稳定的稀土三重键不仅可推动稀土元素价键理论的发展,还能为新型稀土催化剂的设计和先进 功能材料的开发提供新路径。近日,苏州大学谌宁课题组与清华大学李隽课题组合作,创新性地利用富 勒烯分子笼的空间限域和保护作用,采用改良电弧放电技术,成功制备出首个富勒烯内嵌的稀土元素铈 与碳形成的三重键化合物,实现了铈碳三重键的稳定构筑。 X射线单晶衍射分析显示,该结构中铈碳键键 ...
