Abstract

A surface with periodic hydrophobicity gradient (SPHG) is fabricated by shaped femtosecond laser. The directional self-propulsion of the Leidenfrost droplets is realized. The viscous gradient force between gas and liquid is used to drive the droplet to move. A brand-new method for controlling the movement of droplets is provided.

具有周期性疏水性梯度的飞秒激光诱导表面上的自推进莱顿弗罗斯特液滴
利用成型飞秒激光制造出了具有周期性疏水梯度(SPHG)的表面。 莱顿弗罗斯特液滴的定向自推进得以实现。 气体和液体之间的粘性梯度力被用来驱动液滴移动。 这提供了一种控制液滴运动的全新方法。

期刊介绍: ACS Energy Letters is a monthly journal that publishes papers reporting new scientific advances in energy research. The journal focuses on topics that are of interest to scientists working in the fundamental and applied sciences. Rapid publication is a central criterion for acceptance, and the journal is known for its quick publication times, with an average of 4-6 weeks from submission to web publication in As Soon As Publishable format. ACS Energy Letters is ranked as the number one journal in the Web of Science Electrochemistry category. It also ranks within the top 10 journals for Physical Chemistry, Energy & Fuels, and Nanoscience & Nanotechnology. The journal offers several types of articles, including Letters, Energy Express, Perspectives, Reviews, Editorials, Viewpoints and Energy Focus. Additionally, authors have the option to submit videos that summarize or support the information presented in a Perspective or Review article, which can be highlighted on the journal's website. ACS Energy Letters is abstracted and indexed in Chemical Abstracts Service/SciFinder, EBSCO-summon, PubMed, Web of Science, Scopus and Portico.
