Errors that are commonly made in the quantification of biogas from anaerobic digestion experiments were investigated. For liquid displacement gasometers where a barrier solution separates the biogas and the atmosphere, inaccuracy due to gas diffusion was examined experimentally. Acidified saturated saline solution was the most suitable barrier solution, as biogas characteristics changed least w...
Liquids handling is an important issue in biomedical analysis. We propose two different devices for ultrasonic droplets displacement. Each one involve a different physical phenomenon. The first device proposed is a low frequency standing waves using flexural plate waves (FPW). In this case, acoustic radiation pressure is involved for the displacement. The second one uses high frequency travelli...
Nonthermal Brownian motion is investigated experimentally by injecting a particle into soft-mode turbulence (SMT), in the electroconvection of a nematic liquid crystal. It is clarified that the particle motion can be classified into two phases: fast motion, where particles move with the local convective flow, and slow motion, where they are carried by global slow pattern dynamics. We propose a ...
