Inspired by the ancient pinhole camera, researchers have developed a technology to give new insights into the nature of matter. The scanning helium microscope makes it possible to generate images with fine details without the kind of damage to the delicate structures caused by traditional microscopes. For example, one can see the distinct flakes of chitin on a butterfly's wing that resemble plated armour, or the curve of a spider's fang. Matthew's talk will describe how the new technology works and show some of the new types of images that are now possible.
Matthew recently completed his PhD at the University of Newcastle in the Centre for Organic Electronics. He specialises in microscope design and has a particular interest in free jet atomic and molecular beam sources. He also has experience in experimental vacuum science techniques, from vacuum system design through to x-ray techniques, and systems operation and analysis. In 2011 he received an Australian Nanotechnology Network travel fellowship that allowed him to travel to University of Cambridge. While there he was involved in the successful construction of a first-generation helium microscope.
