PLENARY SPEECH: Silvia Vignolini
Professor at University of Cambridge, United Kingdom
Title: Light management for control of visual appearance, from nature to applications
The most brilliant colours in nature are obtained by structuring transparent materials on the scale of the wavelength of visible light. By designing the dimensions of such nanostructures, it is possible to achieve extremely intense colourations over the entire visible spectrum without using pigments or colorants. Colour obtained through structure, namely structural colour, is widespread in the animal and plant kingdom. Such natural photonic nanostructures are generally synthesised in ambient conditions using a limited range of biopolymers. Given these limitations, an amazing range of optical structures exists: from very ordered photonic structures, to partially disordered, to completely random ones.
More about the speaker
Silvia Vignolini is currently a University Professor in Sustainability and Bio-inspired materials at the Chemistry Department in Cambridge. She studied Physics at the University of Florence, Italy. In 2009, she was awarded a PhD in Solid State Physics at the European Laboratory for non-Linear Spectroscopy and the Physics Department at the University of Florence. In 2010, she moved to Cambridge as a post-doctoral research associate working in the Cavendish Laboratory and the Plant Science Department. Her research interest lies at the interface of chemistry, soft-matter physics, optics, and biology. In particular, her research focuses on the study of how natural biopolymers (like cellulose) are assembled into complex architectures within living organisms and they can be exploited to fabricate a sustainable functional materials.
