Visualising Wooden Objects with an Environmental Scanning Electron Microscope.

is a hygroscopic material and so its dimensions and mechanical
properties change with its moisture content. Standard electron
microscopy requires a near perfect vacuum to obtain clear images and
such conditions cause wood samples to dry very rapidly.
ESEM uses a partial vacuum and this together with a cooling stage
permits the analysis of humid, and even saturated, specimens.
Consequently, it is possible to view wood that has never been dried and
is in its natural state.
