【科技日报】中等质量黑洞“进食”白矮星事件或首次被捕捉
Ke Ji Ri Bao· 2026-02-11 01:53
记者10日从中国科学院国家天文台获悉,"天关"卫星可能首次捕捉到中等质量黑洞撕裂并吞噬白矮 星的罕见事件。若最终获得证实,这将是人类首次清晰捕捉到此类极端宇宙现象,对理解黑洞活动规律 及高能天体物理机制具有重要意义。相关研究成果以封面文章形式发表于《科学通报》杂志。 (原载于《科技日报》 2026-02-11 02版) 2025年7月2日,"天关"卫星的宽视场X射线望远镜"万星瞳",在巡天中发现了一个异常明亮且剧烈 变化的X射线源。随后,全球多台望远镜联合观测确认,这一编号为EP250702a的事件发生在一个遥远 星系的外围区域。 "天关"卫星观测数据显示,在剧烈的伽马射线爆发出现前约一天,X射线辐射就已在此位置持续出 现。"这个'前奏'至关重要,它意味着爆发的物理引擎很早就启动了,不同于传统的伽马射线暴。"论文 共同第一作者、中国科学院国家天文台李东悦博士解释道。 该事件呈现出亮度极高、演化极快且位于星系外围等特征,难以用常见的天体爆发模型解释。综合 所有数据,"天关"科学团队提出了最合理的解释:一个中等质量黑洞正在撕裂一颗白矮星。 为何是这对组合?研究团队指出,该事件"衰减极快"与"亮度极高"并存,暗示被 ...

新方法精准操控与高效分离纳米颗粒
Ke Ji Ri Bao· 2026-02-10 23:01
精准操控与高效分离纳米颗粒,一直是生物技术领域的关键瓶颈。为攻克这一难题,芬兰奥卢大学科学 家开发出一种全新的纳米颗粒分离与纯化方法,显著提升了对合成微粒及细胞分泌的纳米级囊泡的分离 纯度。该技术在血液分析、癌症早期诊断、细胞间通信及纳米医学等领域具有广阔应用前景。相关成果 发表于新一期《分析化学》杂志。 团队表示,现有分离技术往往效率低、操作复杂或稳定性差。而新方法仅需常规微通道,即可实现对纳 米颗粒的高效分选。此前,这类尺寸颗粒的分离依赖极易堵塞的纳米通道,且需高压驱动,难以规模 化。相比之下,新技术更快速、精确,且易于放大应用。 实验表明,新方法将聚苯乙烯标准颗粒的分离纯度提升了30%至50%。这类模型颗粒因尺寸均一、形貌 可控、表面性质稳定,广泛用于微流控技术评估。更为重要的是,团队还将癌细胞分泌囊泡的纯度提高 了20%以上,在极小尺度上实现了显著突破。 (文章来源:科技日报) 纳米尺度是生命活动的重要舞台,许多生物过程都发生在这一级别。从体液中提取的细胞外囊泡,如同 身体的"分子信使",能反映疾病的早期信号。然而,若无法有效去除杂质,这些珍贵信息便可能被掩 盖。因此,发展一种高效、温和且可靠的纯化手 ...
瑞典电池巨头破产竟甩锅中国设备?起底背后真相→
Ke Ji Ri Bao· 2026-02-10 14:12
◎ 胡定坤 近日,一些瑞典媒体报道称,未经测试的中国产机器设备导致该国著名电池企业北伏公司(Northvolt)破产。我国驻瑞典大使馆发言人就此答记者问称, 这一说法与事实严重不符,完全站不住脚,属于典型的甩锅推责。 事实正是如此,北伏公司成立后忙于媒体宣传、融资圈钱、盲目扩张、四处建厂,却没有建立起最基础的制造能力。而影响制造能力的因素,绝不仅仅只 有机器设备。据瑞典《诺兰报》调查,北伏公司各个生产线上普遍存在管理混乱、效率低下等问题。还有知情人士爆料称,由于生产工艺设计严重不合 理,其高达80%的产品质量不合格。 这种经营方式的结果就是耗费越来越多,而收入远远赶不上支出,最终融资耗尽、企业倒闭。据统计,2023年1—9月,北伏公司每月亏损超过1亿美元, 但电池交付容量仅79.8兆瓦时,不到2024年计划产能的0.5%。 其实北伏公司的悲剧在成立之初就已注定。据欧洲科技新闻网站《阿里夫报告》报道,对于一家声称要革新绿色能源电池的公司来说,北伏公司的领导团 队缺少一个关键要素——实际经验:竟然没有一位高管之前建造过电池工厂。 可是,一家患有严重"先天病"的公司,是如何拿到上百亿美元的融资的?这确实和中国因素有 ...
