Multistage and passive cooling process driven by salinity difference

Passive Cooling Technologies

Passive optical separation and enrichment of cells by size difference.

A size-selective cell sorting microfluidic device that utilizes optical force is developed. The device consists of a three-dimensional polydimethylsiloxane microstructure comprised of two crossed microchannels in a three-dimensional configuration. A line shaped focused laser beam is used for automatic size-selective cell sorting in a continuous flow environment. As yeast cells in an aqueous med...

Active multistage coarsening of actin networks driven by myosin motors.

In cells, many vital processes involve myosin-driven motility that actively remodels the actin cytoskeleton and changes cell shape. Here we study how the collective action of myosin motors organizes actin filaments into contractile structures in a simplified model system devoid of biochemical regulation. We show that this self-organization occurs through an active multistage coarsening process....

Multistage vacuum membrane distillation (MSVMD) systems for high salinity applications

Multistage membrane distillation (MD) systems can have significantly higher efficiencies than their single stage counterparts. However, multistage MD system design has received limited attention. In this paper, the performance of a multistage vacuum membrane distillation (MSVMD) which is thermodynamically similar to a multi-stage flash distillation (MSF) is evaluated for desalination, brine con...

The multistage process of carcinogenesis

The multi-stage process of carcinogenesis includes initiation, promotion and progression. Initiation usually begins with consecutive damage of several strategic genes such as proto-oncogenes and tumor suppressor genes. In replicating cells DNA damage can be fixed as mutations activating proto-oncogenes and inactivating tumor suppressor genes. Promotion expands initiated cells leading to formati...
