Dr Matthew Weyland - Researcher Profile

Biography

Bringing the nanoworld into sharper focus

The underlying reasons for the behaviour of the materials around us are coded into the arrangement of nanostructures and the atoms within them. Our understanding of the modern world is predicated on the ability to see, characterise and quantify this smallest of length scales. Transmission electron microscopy (TEM) is the most powerful technique for directly decoding the nanoworld - allowing 2D/3D imaging and chemical analysis at resolutions of under 1/10th of a nanometre.
