发表在新一期《微尺度·方法》上的论文称，美国弗吉尼亚理工大学研究团队利用冰自身的物理特性， 开发出一种新型静电除霜技术，通过在冰霜上方施加高电压，使冰晶在静电力作用下脱离表面，实现低 能耗、环保的除霜方式。 随着冰霜晶体的生长，水分子会整齐排列成冰晶格。但有时水分子会"站错队"，这些微小的错误会在霜 层中形成"离子缺陷"，即局部带有正电或负电的区域。 实验显示，即使不施加电压，仅悬挂铜板也能去除约15%的霜。施加120伏电压后，去霜率提升至 40%，550伏时可达50%，说明电压提升能显著增强静电除霜效果。然而，当电压继续升高时，去霜率 却意外下降——1100伏时去霜率降至30%，5500伏仅有20%。分析认为，高电压下霜层的电荷可能向基 底泄漏，导致除霜效率下降。 为解决这一问题，团队采用绝缘玻璃和超疏水基底进行实验。结果显示，在超疏水表面施加高电压时， 去霜效果显著提升，最高可去除75%的霜。 （文章来源：科技日报） 如果在霜层上方放置带正电的电极板，霜中的负离子缺陷会被吸引上移，而正离子缺陷则被排斥向下， 从而使霜层高度极化，产生强烈的静电吸引力。如果这种吸引力足够大，冰晶就会断裂并"跳"向电极。 基于 ...

美国佛罗里达大学科学家在新一期《自然·通讯》杂志发表论文称，全球广泛使用的便携式基因测序仪 存在未知的安全隐患，可能导致私人基因数据在无察觉的情况下泄露或被篡改。 研究团队在牛津纳米孔公司生产的MinION便携式测序仪及其配套软件中，识别出3处安全漏洞。其中两 处漏洞可使未经授权者擅自访问设备，在用户不知情时复制或修改DNA数据；第三处缺陷则易引发"服 务中断"问题，测序过程中止，导致设备呈现故障状态。尽管牛津纳米孔公司已根据安全人员提示发布 软件更新以修复漏洞，但若设备继续使用旧版软件或接入不安全的网络系统，仍面临被攻击的风险。 团队表示，仅有手掌大小的MinION测序仪售价数千美元，可在全球任意地点操作，彻底改变了以往 DNA测序工作流程复杂、成本高昂的局面。然而，这种便利性也带来了新的安全隐患，测序仪需连接 计算机运行，而计算机若接入不安全网络，或在野外等非受控环境中感染恶意软件，便可能成为数据泄 露的突破口。 目前这类纳米孔测序仪仅用于科研领域，尚未应用于临床诊断。但团队强调，即便是科研用途，这些设 备同样涉及人类DNA的测序分析。 值得注意的是，美国国家标准与技术研究院在最新发布的指南草案中，已开始 ...
