When biology meets materials science – Interdisciplinary applications of electron microscopy

Journal of Microscopy, EarlyView.
Abstract Research at the interface between biology and materials science creates challenges for electron microscopists. Everything from the sample preparation to the choice of imaging and analytical techniques and the interpretation of the resulting data refuses to sit comfortably within the domain of one discipline or the other.

TEM TOMATE, TEM QUÍMICA:

Revista Interdisciplinar em Ensino de Ciências e Matemática
O ensino de Química, especialmente de ácidos e bases, é frequentemente criticado por sua abordagem abstrata e descontextualizada. Este trabalho teve como objetivo propor, aplicar e analisar uma atividade experimental investigativa que tenta superar essa lacuna, utilizando o tomate como tema central.

Preparation artefacts mask the detectability of crosslinking‐induced structural changes in electron microscopy of collagen hydrogels

Journal of Microscopy, EarlyView.
Abstract Collagen hydrogels are widely used as biomimetic three‐dimensional matrices whose mechanical behaviour depends strongly on fibrillar micro‐ and nanoarchitecture and crosslinking state. Electron microscopy offers high spatial resolution for structural analysis, but sample preparation can substantially distort highly hydrated collagen networks ...
