Desde la implantación del Espacio Europeo de Educación Superior (EEES), las universidades han tenido que hacer frente a una serie de retos. Entre ellos, destaca la obligación de poner en marcha una estrategia que tiene como fin reducir las altas tasas de abandono de los estudios, fenómeno que se produce tanto a nivel nacional como internacional (González-Ramírez & Pedraza-Navarro, 2017).En España, los datos aportados por el Ministerio de Ciencia, Innovación y Universidades (2020) para la cohorte de nuevo ingreso del curso 2013-2014, arrojan una tasa de abandono del 33,9%. Este porcentaje muestra, además, cierto tipo de

Mixing a small amount of liquid into a powder can give rise to dry-looking granules; increasing the amount of liquid eventually produces a flowing suspension. We perform experiments on these phenomena using Spheriglass, an industrially-realistic model powder. Drawing on recent advances in understanding friction-induced shear thickening and jamming in suspensions, we offer a unified description of granulation and suspension rheology. A 'liquid incorporation phase diagram' explains the existence of permanent and transient granules and the increase of granule size with liquid content. Our results point to rheology-based design principles for industrial granulation.Incorporating a small amount of liquid into powders is a ubiquitous unit operation in industrial materials processing. In some cases, a minimal amount of liquid is used to produce matt solid granules. Such 'wet granulation' 1 has long been used in the manufacturing of, e.g., detergents, drugs 2 and gunpowder 3 . When too much liquid is added, the mixture becomes (in granulation jargon) 'overwet' 4 : it turns into a flowing suspension and granulation fails. However, such high-1
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
