They are obtained from an adapted sol\u2013gel process combined with phase separation phenomena that occur within the water droplets of an emulsion. We present here a methodology based on cryogenic scanning electron microscopy (cryo-SEM) that allows, with minimal specimen preparation, the direct and in situ visualization of \u2018wet\u2019 alkoxide-derived microstructures, for the mechanistic study of the complex process of MICROSCAFS\u00ae generation. It is simultaneously combined with energy dispersive X-ray spectroscopy (EDS) to visualize phase separation phenomena and study the chemical elemental composition at specific regions of the sample and reaction times.<\/jats:p>","DOI":"10.3390\/gels9090704","type":"journal-article","created":{"date-parts":[[2023,9,1]],"date-time":"2023-09-01T09:12:22Z","timestamp":1693559542000},"page":"704","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Mechanistic Study of the Formation of Multicomponent Oxide Porous Microspheres (MICROSCAFS\u00ae) by Cryo-Scanning Electron Microscopy"],"prefix":"10.3390","volume":"9","author":[{"given":"M\u00e1rio","family":"Vale","sequence":"first","affiliation":[{"name":"CERENA, DEQ, Instituto Superior T\u00e9cnico, Universidade de Lisboa, Av.
