Novel hot electron-emitting working electrodes and conventional counter electrodes were created by screen printing. Thus, low-cost disposable electrode chips for bioaffinity assays were produced to replace our older expensive electrode chips manufactured by manufacturing techniques of electronics from silicon or

Morphological properties of atmospheric particles are directly related to their residence time and transport behaviors, and their deposition patterns in human respiratory systems. The projected properties of particles measured by transmission electron microscopy (TEM) were combined with the particle height

In this study, membrane biofouling caused by bacteria that have different characteristics was evaluated using flow field-flow fractionation (FlFFF). Three different bacteria which differed from size and shape (Staphylococcus epidermidis, Escherichia coli, Flavobacterium lutescens) were investigated with GM ultrafiltration (UF
