A force and/or torque are induced in a material under the imposition of a magnetic field. Their magnitudes are different from those acting on the surrounding materials because of the difference in their physical properties. Therefore, a magnetic field is a powerful tool for controlling a second phase in a mother phase such as particles suspended in a liquid. In this paper, we focus on two proce...

Dispersive solid-phase extraction (DSPE) combined with ultrasound-assisted emulsification microextraction (UAEME) has been developed as a novel approach for the determination of lead and cadmium in food and environmental samples prior to graphite furnace atomic absorption spectrometry. SBA-15/CCMet was synthesized and used as a new sorbent for the extraction of metal ions in DSPE. It was charac...

A new high precision contact scanning probe possible to measure miniature components on a micro/nano-CMM is proposed. This contact probe is composed of a fiber stylus with a ball tip, a floating plate and focus sensors. The ball tip is fabricated using optical fiber with melting and solidification processes. The stylus is attached to a floating plate, which is connected to the probe housing via...

Food powders often exhibit hydrophobic surface areas. To understand the effect of corresponding wettability variations on particle floating, which critically influences powder reconstitution, we studied floating glass beads after creating heterogeneity by spraying cocoa butter. Force-position curves were recorded to characterise contact line pinning. Floating particles with heterogeneities comp...
