The rich diversity of man-made complex fluids and naturally occurring biofluids is opening
up new opportunities for investigating their flow behavior and characterizing their …

Viscosity, as a crucial property of liquids, plays a vital role in various fields, including food,
chemical, pharmaceutical, personal care, and biomedicine. Therefore, it is of great …

Physical characterization of viscous samples is crucial in chemical, pharma and petroleum
industry. For example, in the refining industry of petroleum, water percentage is verified by …

We propose a novel device capable of measuring relaxation times of viscoelastic fluids as
small as 1 ms. In contrast to most rheometers, which by their very nature are concerned with …

In this study, a microfluidic-based physiometer capable of measuring whole blood viscosity,
hematocrit, and red blood cell (RBC) deformability on a chip is introduced. The physiometer …

Viscosity measurements have a wide range of applications from industrial chemical
production to medical diagnosis. In this work, we have developed a simple droplet-based …

In cystic fibrosis (CF) patients airways mucus shows an increased viscoelasticity due to the
concentration of high molecular weight components. Such mucus thickening eventually …

Blood viscosity is considered as a vital determinant of the efficiency of blood flow in blood-
vessel networks. The coflowing method is considered as a promising technique for …

We report a stress-controlled microfluidic shear viscometer with flow visualization aided by
smartphone technology. The method involves driving the fluid into a microchannel at …

Gas injection plays an important role in bubble formation in microfluidics. The effects of the
gas feed on the formation of N2 bubbles in a microfluidic T-junction is highlighted under …
