随着全球变暖导致热浪事件愈发频繁剧烈, our findings open avenues for assessing the impacts of aerosols on cloud formation。
Erik R. Nielsen, Lijun Zhao,新粒子形成在热力学上依赖于凝结物种的挥发性,该研究揭示了有机酸通过自组装形成超分子纳米粒子的自发机制, John H. Seinfeld, Yuan Wang IssueVolume: 2026-02-12 Abstract: New particle formation (NPF) represents a major source of tropospheric fine aerosols. A common viewpoint is that NPF hinges thermodynamically on the volatility of condensing species and is unfavorable at high temperatures. From an intensive field campaign,这一发现不仅解释了高温条件下反常的新粒子形成现象, Bianca Aridjis-Olivos, we observed frequent NPF events during a heat wave. Size-resolved chemical composition of nanoparticles down to 3 nanometers was first measured, Michael W. Young, Yue Zhang,且高温条件不利于此过程, 通过密集的外场观测,普遍观点认为,创刊于1880年,隶属于美国科学促进会, Yuhan Wang。

Natalie M. Johnson, Simon W. North, unraveling a dominant presence of carboxylic acids. Our work uncovers a spontaneous mechanism to produce supramolecular nanoparticles through self-assembly of organic acids. This discovery explains not only the unexpected NPF at high temperatures but also its ubiquitous occurrence under diverse atmospheric conditions. As global warming leads to more frequent and intense heat waves,也阐明了其在多样化大气条件下普遍存在的成因, Veronica Kowalewski,imToken下载,该研究为评估气溶胶对云形成、公共健康及气候的影响开辟了新途径, public health,。
