This is an extension of the Fellowship: 'NEMESIS' (New Mathematics for Materials Modelling in the Engineering Sciences and Industrial Sectors).Advanced materials sit at the heart of modern technology and are at the forefront of many improvements in quality of life. Key to enhancing material properties is a deep understanding of the link from microstructure to macroscale properties. This requires a diverse range of science including theoretical modelling, computational simulation and experimentation. This Fellowship Extension project sits at the triple point of these approaches and principally, uses the experience of the team, in particular in advanced mathematical modelling in order to design new materials for a range of applications. Three themes will be considered, "Reinforced syntactic foams", "Acoustic metamaterials" and "Thermal metamaterials" and a programme of Public Engagement will illustrate the research to a wide audience. Syntactic foams offer stiff, lightweight materials with strong recoverability, even after significant loading. This theme will investigate the ability of reinforcements including families of 2D materials and other micro and nano fillers in order to enhance stiffness whilst maintaining weight and recoverability. Iteration between models and experiments will ensure that optimise properties are determined. Applications are in marine structures, although a very well-publicised use of syntactic foams was in the football used in the 2006 world cup!Acoustic metamaterials are providing us with new way to manipulate sound. This theme builds on the recent work of the principal investigator's team where, together with an industrial partner he developed and subsequently built microstructured materials that were able to simultaneously slow down sound and also ensure that sound could penetrate the structure. This is a highly non-trivial task and the realisation of such a medium means that it can now potentially be employed in applications where it is important to manipulate sound. Classical examples are in sound attenuation devices, which using this approach could be made more compact. This theme will therefore look to better the designs using more complex microstructures and utilise the medium in more complex geometries. Thermal metamaterials are new media that look to manipulate heat flow and temperature fields. Research so been to direct thermal fields so that regions of space fare protected from high temperatures. In many applications associated with thermal efficiency, it is important to ensure uniform temperature distributions in electronic devices or regions of space within those devices. This is difficult to achieve in complex geometries. This project will look to design and realise new thermal metamaterials whose aim is to be deployed in specific complex geometries in order to ensure thermal uniformity and therefore enhanced heat dissipation and thus improved energy efficiency.The public engagement theme will use results from the original Fellowship of the PI, together with new results from the Extension in order to devise a programme of public engagement with the specific remit of widening participation in Mathematics, Science and Engineering. This will be achieved by devising talks and events aimed at School children, using stands and exhibitions at Science fairs, national competitions and web and social media presence in order to reach out to as broad a community as possible. This inter-disciplinary project is ideal for this in the sense that it sits many academic fields, with its core in Applied Mathematics but employing ideas from Materials Science, Chemistry, Engineering and Physics in order to achieve its goals.

这是该奖学金的延伸：“NEMESIS”（工程科学和工业领域材料建模新数学）。先进材料是现代技术的核心，也是许多生活质量改善的前沿。提高材料性能的关键是深刻理解微观结构与宏观性能之间的联系。这需要各种各样的科学，包括理论建模，计算模拟和实验。该研究金扩展项目位于这些方法的三点，主要使用团队的经验，特别是在高级数学建模方面，以便为一系列应用设计新材料。会议将考虑三个主题：“增强复合泡沫”、“声学超材料”和“热超材料”，以及一个公众参与计划，向广大观众展示研究成果。句法泡沫提供坚硬，轻质材料，具有很强的可恢复性，即使在显著加载后。本主题将研究增强材料的能力，包括二维材料家族和其他微纳米填料，以提高刚度，同时保持重量和可恢复性。模型和实验之间的迭代将确保确定最优属性。虽然句法泡沫在2006年世界杯足球比赛中使用得很好，但它的应用也在海洋结构中。声学超材料为我们提供了操纵声音的新方法。这个主题建立在首席研究员团队最近的工作基础上，在那里，他与一个工业合作伙伴一起开发并随后建造了微结构材料，这种材料能够同时减慢声音，并确保声音能够穿透结构。这是一项非常重要的任务，这种媒介的实现意味着它现在可以潜在地用于处理声音的应用中。典型的例子是声音衰减装置，使用这种方法可以使其更紧凑。因此，这个主题将着眼于更好的设计，使用更复杂的微观结构，并在更复杂的几何形状中利用介质。热超材料是一种旨在控制热流和温度场的新型介质。研究人员一直在引导热场，以保护太空区域免受高温的影响。在许多与热效率相关的应用中，确保电子设备或这些设备内空间区域的均匀温度分布是很重要的。这在复杂的几何形状中很难实现。该项目将着眼于设计和实现新的热超材料，其目标是在特定的复杂几何形状中部署，以确保热均匀性，从而增强散热，从而提高能源效率。公众参与主题将使用原始PI奖学金的成果，以及扩展项目的新成果，以设计一个公众参与计划，其具体职责是扩大数学、科学和工程的参与。这将通过设计针对在校儿童的讲座和活动、利用科学博览会的展台和展览、全国竞赛以及网络和社交媒体的存在来实现，以便尽可能广泛地接触到一个社区。这个跨学科项目是理想的，因为它涉及许多学术领域，以应用数学为核心，但采用材料科学，化学，工程和物理的思想来实现其目标。
