An evaporating colloidal particle–laden droplet leaves behind a ring-like residue after drying. We routinely observe this ubiquitous phenomenon for dried coffee drops; thus, it is known as the "coffee ...

In joint research with the University of Tokyo (UTokyo), the National Institute of Advanced Industrial Science and Technology ...

Modelling and monitoring HCHO is essential for protecting public health, mitigating environmental impacts, regulating industrial emissions, and advancing our understanding of atmospheric chemistry. In ...

Polymeric foams are increasingly used across industries, contributing to material and energy efficiency. In particular, chemical blowing agents (CBAs) are widely used in foaming processes due to their ...

Solutions of very low concentrations cannot be treated by the usual concept of concentration. Stochastic calculations are performed for the analysis of such solutions containing one or a few ...
