The transport of minute amounts of liquids using microfluidic systems has opened avenues for higher throughput and parallelization of miniaturized bio/chemical processes combined with a great economy of reagents. In this report, we present a microfluidic capillary system (CS) that autonomously transports aliquots of different liquids in sequence: liquids pipetted into the service port of the CS...

Capillary porosity percolation in a hydrating cement paste has a large influence on transport properties and durability. Percolation can be examined using low-temperature calorimetry and using microstructure models. In this paper, the two approaches are compared for cement pastes with different water-to-cement ratios and exposed to various curing conditions. The influence of sealed curing is se...

This article explores how common misunderstandings about the microcirculation - that capillary supply varies directly with O(2) demand, that local capillary supply in muscle is determined by fibre type and that it is appropriate to model capillary distribution as either random or in a fixed geometric pattern - arise from quantifying capillarity by simple measures of quantitative extent, rather ...

This article is available online at http://www.jlr.org The lipolytic processing of triglyceride-rich lipoproteins (e.g., chylomicrons, very low density lipoproteins) by lipoprotein lipase (LPL) is the central event in plasma triglyceride metabolism and plays a crucial role in the delivery of lipid nutrients to parenchymal cells (e.g., adipocytes, myocytes) ( 1–4 ). LPL is synthesized by parench...

Two-phase passive heat transport devices such as vapor chambers, loop pipes, and capillary pumped loops utilize porous evaporators for phase change to drive fluid transport. Nucleate boiling can occur within capillary-fed evaporators, especially under high-heat-flux operation, has been visually observed in various experimental studies the literature. However, prior modeling efforts have typical...

In nature, capillary forces are often driving microfluidic propulsion and droplet manipulation, technologies have been developed to utilize these in applications such as lab-on-a-chip biosensors systems. At the same time, responsive materials that can be activated by a variety of external triggers, including light, electric fields, temperature, locally deform create dynamic surface structures, ...

Morphological and physiological studies indicate multiple routes for transport across capillary endothelium. However, the identification of the morphological counterparts of specific transport processes (or the assignment of specific transport roles to morphologically identifiable pathways) has been only partly achieved: the contribution of endothelial cell membranes to transport of water and s...
