Rheology for Traffic Safety

Posted on Leave a commentPosted in LifeLog, Rheology

Very interesting movie below, in which a nice application of rheology to safety is demonstrated. This is actually the application of shear thickening liquids, for which the viscosity increases with increasing shear rate. The famous application is d3o and mainly for sports. The other famous example is the STF for military usage. Several years back, […]

It is pity that I did not recognize the importance of this study (see page 17), which has received The 2017 Ig Nobel Prize. Below is the ceremony, but almost nothing for the research was presented. http://www.improbable.com/ig/2017/ The video linked to the paper would be sufficient to demonstrate the fun of this study. Nevertheless, the […]

I found this paper very interesting. From my phD study, Brownian motion of DNA molecules has been observed via fluorescent microscope, and typical observed behavior of DNA is as shown above. (This movie was taken by Mr Sato who graduated form my group when I was in Tokyo University of Agriculture and Technology.) Just following […]

“Coffee ring” for liquid crystals

Posted on Leave a commentPosted in Rheology

An interesting article for the topic above. As shown in the photo above, when a drop of coffee is put on a substrate, after the drying process the drop exhibits a ring pattern. This phenomenon has been of course well-known in our daily life, and has been discussed in the soft-matter community. The pioneering work […]

Thrombelastography

An interesting article for clotting of human blood, I have found. I can imagine that clotting (solidification) of blood has significant effects on surgeries and other medical operations. But I did not know how people quantify it. According to the article above, medical people make rheological measurements so-called thrombelastography. Because I did not know the […]
