    Developing supply chain innovations - requirements for research and challenges for the food industry

    The European food system serves 480 million people each day with food and drink (Raspor, McKenna & de Vries, 2007). It is of intense current research interest to understand how food purchase choice will impact on resource use, climate change and public health (Deloitte, 2007). It is clear that the current food needs of consumers in developed nations are becoming more complex with consideration of environmental impact, social responsibility, functional foods, nutraceuticals, obesity and food miles, amongst many issues, driving the emergence of new products (UK Cabinet Office Strategy Unit, 2008). The research reported here shows how aspects of food manufacture can enhance the quality control, decrease environmental impact and improve traceability of products in food supply chains. We specifically use examples of accounting for carbon dioxide emissions, water use and food production / transport approaches in supply chains to show how manufacturers can improve their operational awareness of such factors and stimulate innovative solutions. The research presented also considers the impact of developing comprehensive sensory and consumer research when new manufacturing practices are utilised

    On the best method of relaxing the dried skins of birds and other animals

    Observing in the Museum of the Royal Society of Tasmania a valuable and not an inconsiderable collection of bird skins from different countries, which will require, eventually, to be mounted or set up in their natural attitudes, I think it very desirable to lay before the Society the method of relaxing such skins, as pursued by the best animal preservers in Europe, and the efficiency of which I have repeatedly proved

    From soft harmonic phonons to fast relaxational dynamics in CH3_{3}NH3_{3}PbBr3_{3}

    The lead-halide perovskites, including CH3_{3}NH3_{3}PbBr3_{3}, are components in cost effective, highly efficient photovoltaics, where the interactions of the molecular cations with the inorganic framework are suggested to influence the electronic and ferroelectric properties. CH3_{3}NH3_{3}PbBr3_{3} undergoes a series of structural transitions associated with orientational order of the CH3_{3}NH3_{3} (MA) molecular cation and tilting of the PbBr3_{3} host framework. We apply high-resolution neutron scattering to study the soft harmonic phonons associated with these transitions, and find a strong coupling between the PbBr3_{3} framework and the quasistatic CH3_{3}NH3_{3} dynamics at low energy transfers. At higher energy transfers, we observe a PbBr6_{6} octahedra soft mode driving a transition at 150 K from bound molecular excitations at low temperatures to relatively fast relaxational excitations that extend up to \sim 50-100 meV. We suggest that these temporally overdamped dynamics enables possible indirect band gap processes in these materials that are related to the enhanced photovoltaic properties.Comment: (main text - 5 pages, 4 figures; supplementary information - 3 pages, 3 figures
