公募基金费率改革不断提速 第二批浮动费率基金发行节奏显著快于预期 从渠道获悉，中欧核心智选混合基金因募集规模突破20亿元提前结束发行，易方达价值回报混合同样宣 布提前结束募集，第二批浮动费率基金发行节奏显著快于预期。近年来，公募基金费率改革不断提速。 自证监会今年5月发布《推动公募基金高质量发展行动方案》以来，浮动费率机制被视为行业重点试点 方向。此次中欧核心智选、易方达价值回报混合的提前结募，反映出该类产品正获得市场快速认可。有 业内人士指出，浮动费率基金通过将管理费与投资者收益直接挂钩，实现"多赚多收、少赚少收"，在利 益共担的机制下，有望强化基金经理的责任感与长期投资动力。 (证券时报) 存量改规则、新品新机制 权益类基金加大分红力度 数据显示，截至8月13日，今年以来基金分红总额达到1415亿元，较去年同期大幅增长近40%。其中， 权益类基金分红金额猛增，达到348.84亿元，是2024年同期的3倍多。权益类基金分红金额激增的原因 主要有两方面：一是业绩打底，今年权益类基金整体表现强劲；二是基金公司对投资者体验的重视程度 不断提升，通过分红增强持有人获得感。（上证报） 沪指突破拉动公募赚钱效应 股基增 ...

Market Dynamics - The State Administration for Market Regulation and the Ministry of Industry and Information Technology are drafting a notice to strengthen the recall and supervision of intelligent connected new energy vehicles, preventing misleading marketing and ensuring product safety and consistency [1] Company Developments - Apple is planning to re-enter the artificial intelligence sector with new products, including large robotic arms for retail and manufacturing, a home security ecosystem, and an updated version of Siri with conversational capabilities [4] - Tencent Holdings reported a second-quarter revenue of 184.5 billion yuan, a year-on-year increase of 15%, with net profit attributable to shareholders reaching 55.63 billion yuan, up 17% [5] - Zhengfan Technology announced plans to acquire 62.2318% of Hanjing Semiconductor for 1.12 billion yuan, aligning with its strategic development goals [7] Industry Events - The first full-size humanoid robot competition in China will take place in Hefei from August 23 to 24 [6] Technology Advancements - Chinese researchers have developed lithium batteries with energy densities exceeding 600 watt-hours per kilogram, improving energy density and endurance by 2-3 times compared to existing lithium-ion batteries [10]

Group 1 - A recent study led by a team from Rice University has achieved the strongest phonon interference effect in silicon carbide systems to date, known as "Fano resonance," with an intensity two orders of magnitude higher than previously reported [1] - This phonon-based technology is expected to advance molecular-level sensing technology and open new application pathways in energy harvesting, thermal management, and quantum computing [1] - The breakthrough relies on constructing a two-dimensional metallic interface on a silicon carbide substrate, significantly enhancing the interference effect of different vibration modes within silicon carbide [1] Group 2 - The interference sensitivity is high enough to detect single molecules without the need for chemical labels, and the device is simple and scalable, promising applications in quantum sensing and next-generation molecular detection [2] - In low-temperature experiments, the team confirmed that this effect is entirely due to phonon interactions rather than electronic effects, making this "pure phonon" quantum interference rare and specific to the two-dimensional metal/silicon carbide system [2]
