This phenomenon, known as the "bottleneck effect" is here revisited from a different perspective, by using confined displacements of interfacial fluids. Compared to standard microfluidics, such effect admits in this case a neat quantitative characterization, which reveals intrinsic material characteristics of flowing monolayers and permits to envisage strategies for their controlled micromanipulation.4 p.application/pdfeng(c) American Physical Society, 2008Dinàmica de fluidsPel·lícules finesSuperfícies (Física)Fluid dynamicsSurfaces and interfacesThin films and nanosystemsinfo:eu-repo/semantics/article559134info:eu-repo/semantics/openAccess
