Airborne and deposited water microdroplets can carry viruses including coronaviruses. The evaporation of containing virus particles often leads to inactivation. Microdroplet involves various mechanisms such as diffusion, the Kelvin effect, infrared irradiation, role solutes. For airborne microdroplets, temperature relative humidity ambient air are important factors. However, for sessile droplet...

In recent years, joining technologies have been developed owing to multi-materials. From the viewpoint of recycling, separating joined materials is necessary when they are disposed. Our previous study steel and aluminum plates showed that easy separation by foaming area at time disposal effective. Still, it could not be applied a single plate. this study, we attempted use agent interface before...

Bed symmetry has been analysed in fountain confined conical spouted beds operating with fine particles. Thus, vertical particle velocities and the spout shape have determined a wide range of spouting air bed configurations. is widely accepted without draft tubes or nonporous ones, but this not case when open-sided are used. radial velocity profiles differ depending on cross-sectional angular pl...

Analysis of multiple equilibria compounds with different coordination sites is extended to the description adsorption isotherms focus on low relative pressure range. The entropy evolution described using particle distribution theory which also holds for adsorbents consisting materials bearing more than one type and applies condition that adsorptive-adsorbent binding strength larger adsorptive-a...
