Gas and vapor nucleation in fluids under confinement or at textured surfaces is central for many phenomena of technological relevance, such as bubble release, cavitation, and biological growth. Understanding and developing quantitative models for nucleation is the key to control how bubbles are formed and to exploit them in technological applications. An example is the in silico design of textured surfaces or particles with tailored nucleation properties. However, despite the fact that gas\/vapor nucleation has been investigated for more than one century, many aspects still remain unclear and a quantitative theory is still lacking; this is especially true for heterogeneous systems with nanoscale corrugations, for which experiments are difficult. The objective of this focus article is analyzing the main results of the last 10-20 years in the field, selecting few representative works out of this impressive body of the literature, and highlighting the open theoretical questions. We start by introducing classical theories of nucleation in homogeneous and in simple heterogeneous systems and then discuss their extension to complex heterogeneous cases. Then we describe results from recent theories and computer simulations aimed at overcoming the limitations of the simpler theories by considering explicitly the diffuse nature of the interfaces, atomistic, kinetic, and inertial effects.<\/jats:p>","DOI":"10.1063\/1.4964395","type":"journal-article","created":{"date-parts":[[2016,10,24]],"date-time":"2016-10-24T17:00:27Z","timestamp":1477328427000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":41,"title":["Focus Article: Theoretical aspects of vapor\/gas nucleation at structured surfaces"],"prefix":"10.1063","volume":"145","author":[{"given":"Simone","family":"Meloni","sequence":"first","affiliation":[{"name":"Department of Mechanical and Aerospace Engineering, Sapienza University of Rome, via Eudossiana 18, 00184 Roma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2735-6982","authenticated-orcid":false,"given":"Alberto","family":"Giacomello","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Aerospace Engineering, Sapienza University of Rome, via Eudossiana 18, 00184 Roma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlo Massimo","family":"Casciola","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Aerospace Engineering, Sapienza University of Rome, via Eudossiana 18, 00184 Roma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2016,10,24]]},"reference":[{"key":"2023062607244742500_c1","doi-asserted-by":"publisher","first-page":"365","DOI":"10.1146\/annurev.fluid.30.1.365","volume":"30","year":"1998","journal-title":"Annu.
