The samples for HRTEM analysis were prepared using an ultramicrotomy with a Leica Ultracut UCT (Leica Microsystems GmbH, Vienna, Austria).
Lines or scratches in surfaces, appearing after ultramicrotomy cutting due to the resol fragility, made difficult the observation of individual layers.
The specimens were prepared by ultramicrotomy (Ultracut S from Leica), and some samples were exposed to osmium tetroxide ([O.
The samples for transmission electron microscopy (TEM) analysis were prepared using an ultramicrotomy with a Leica Ultracut UCT (Leica Mikrosystems GmbH, Vienna, Austria).
Through this analysis it is possible to evaluate particle parameters such as thickness, length, aspect ratio, and interparticle distance, although a more recent study has shown that the image analysis underestimates the length and aspect ratio of the particles, due to effects that arise from the preparation of TEM samples by ultramicrotomy and to projection effects caused by the wavy shape of the clay particles (15).
