Paleoenvironmental reconstructions on the Cerro Blanco subcomplex of Nevados de Chillán volcano, using volcanic facies (Winner)
Authors: Jennie S. Gilbert, Katy Mee and Hugh Tuffen
Nevados de Chillán volcano, central Chile (Fig. 1) has been active for at least 640 ka(1) and continues to be active at the present day. Eruptions have occurred during both glacial and intergalcial periods, with frequent interaction between volcanic products and snow and ice of varying thicknesses.
Field evidence and volcanic textures from three andesitic lavas from the Cerro Blanco subcomplex of Nevados de Chillán are used here to aid reconstructions of former eruptive environments.
Supportive or suggestive? Using drawings to help children talk about touch (Runner-Up)
Authors: Deirdre Brown (Lancaster University, UK), Michael Lamb (Cambridge University, UK), Margaret-Ellen Pipe (NICHD, USA), Yael Orbach (NICHD, USA), Charlie Lewis (Lancaster University, UK)
In cases of child abuse children are often the only witness or source of evidence, but what they tell investigators is often insufficient to secure a conviction or acquittal.
Researchers have therefore explored techniques that can support children to tell as much as possible about what they have seen or experienced, without compromising the accuracy of the information they report.
Identifying and evaluating these techniques is important to ensure that children are adequately protected from their abusers, but also to ensure that innocent defendants are not wrongfully convicted.
Nanostructures for Optoelectronic Devices Grown using Molecular Beam Epitaxy (Runner-Up)
Authors: M.Stone, Q.Zhuang, A.Godenir, R.Jones, A.Krier
Molecular-Beam Epitaxy (MBE) is an ultra-high vacuum technique for the production of high quality semiconductor nanostructures. The special merit of this technique is that epitaxial layers can be grown with thickness control at the single monolayer level and precise control over alloy composition and doping levels.
Our research involves using MBE in the quantum engineering of novel semiconductor nanostructures with optimized electrical and optical properties for the development of next generation LEDs, lasers and photodetectors operating in the mid-infrared (2-5 µm) spectral range.
