Environmental scanning electron microscopy as a new technique to determine the hygroscopic behavior of individual aerosol particles.
On the other hand, this hygroscopic ability would mean vulnerability for exposure to liquid water.
Also, since glycerine is strongly hygroscopic, the prepared fluid must be kept sealed from the atmosphere as much as possible.
They survive by occupying the endolithic niche among the hygroscopic halite crystals, which is able to condense moisture from occasional fog or dew.
The hair, like so many hygroscopic substances, takes up a weight of water from the air which depends on the relative humidity, irrespective of temperature.
One mechanism involves a highly hygroscopic fluid secreted by the tick that is hydrated by water vapour from the surrounding atmosphere, and is then re-ingested into the tick.
Dry fronds and empty bunches burn much more easily than husks, which are a very hygroscopic.
In short, containers that are good for preserving cold drinks or potato crisps for a few months have been mistakenly judged adequate to preserve highly hygroscopic dry seeds for decades.
