Chemosensation is important for the survival and reproduction of animals.The odorant binding proteins (OBPs) are thought to be involved in chemosensation together with chemosensory receptors.While OBPs were initially considered to deliver hydrophobic odorants to olfactory receptors in the aqueous lymph solution, recent studies suggest more complex

Many viruses, such as coronaviruses, tend to spread airborne inside water microdroplets.Evaporation of the microdroplets may result in a reduction of their contagiousness.However, the evaporation of small droplets is a complex process involving mass and heat transfer, diffusion, convection and solar radiation absorption.Virological studies indicate
