Liquid-phase exfoliation via shear flow is a widely adopted technique for the large-scale production of graphene. However, the underlying nano- and microscale exfoliation mechanisms remain poorly understood. In this work, ...
Mikaberidze, Guram; Artime, Oriol; Díaz Guilera, Albert; D'Souza, Raissa M. (Publication date: 2026-03-17)
Network flows are pervasive, including the movement of people, transportation of goods, transmission of energy, and dissemination of information; they occur on a range of empirical interconnected systems, from designed ...
(Publication date: 2026-03-16)
We investigate the transport of superparamagnetic colloidal particles along self-assembled tracks using a periodically applied magnetic field as a model for ratchetlike mechanisms. Through video microscopy and simulations, ...
Pérez González, Carlos; Alert Zenón, Ricard; Blanch Mercader, Carles; Gómez González, Manuel; Kolodziej, Tomasz; Bazellières, Elsa; Casademunt i Viader, Jaume; Trepat Guixer, Xavier (Publication date: 2026-03-13)
Development, regeneration and cancer involve drastic transitions in tissue morphology. In analogy with the behaviour of inert fluids, some of these transitions have been interpreted as wetting transitions. The validity and ...
Coronas, Luis Enrique; Vilanova, Oriol; Franzese, Giancarlo (Publication date: 2026-03-10)
Water is essential for life, and its unique properties present significant scientific challenges because of our limited understanding of its thermodynamic behavior. This knowledge gap hinders the accurate theoretical ...
Álvarez Braña, Yara; Benavent Claró, Andreu; Benito López, Fernando; Hernández Machado, Aurora; Basabe Desmonts, Lourdes (Publication date: 2026-03-10)
To enhance the portability of Lab-on-a-Chip technology, avoiding bulky electronic flow control systems is crucial. Self-powered microfluidics can significantly improve portability by eliminating the need for electronic ...
