【讲座信息】

目前，科学家们在新材料设计和加工战略和方法的发展方面取得了重大进展。在这里，我们特别强调了多功能组合的优势，以实现对材料性能的协同增强效应。包括碳涂层与带工程相结合以改变电子性能；形貌控制的通用方法；物理约束与催化效应相结合以控制金属硫电池中多硫化物的损失；多种应变工程用于改进超导体中的通量钉扎和催化剂中的反应位点；用于控制纳米材料尺寸、形状和成分等生长的加和减工程；实现优化的电子、离子和光学性能的多维操作；设计蛋黄壳球/核壳结构用于控制不需要的应变；在材料、结构和装置层面进行交叉，以实现高活性催化剂和存储材料的制备。无论是在基础还是应用层面，界面/表面科学和工程是材料设计和加工的最关键要素。我们的大多数研究都局限于研究投入到研究产出的范围内，而研究产出和商业应用之间存在巨大差距，这也是需要我们重视的问题。在从实验室到实际应用的工业转化过程中，扩大规模达到量产仍然是一大挑战。

Significant advances in development of strategies and approaches on novel materials design and processing have been made. Here we particularly highlight the advantages of combination of multi-functionalities to achieve synergetic effect on materials performance. These include combination of carbon coating with band engineering for alteration of electronic properties; universal general approach for morphology control; combination of physical confinement with catalytic effect to control polysulphide loss in metal sulphur battery; Multiple strain engineering for improvement of flux pinning in superconductor and reactive sites in catalysts; Additive & subtractive engineering for controlled growth of nanomaterials with designed size, shape and composition; Multiple dimension manipulation to achieve optimised electronic, ionic and optical properties; York-shell sphere/Core-shell structures to control unwanted strain; Hybridisation at materials, structure & device level to achieve high reactivity in catalysts and storage materials. Among these the interface/surface science and engineering is the most critical element for materials design and processing at both fundamental and applied level. Most of our research is limited within the block of research inputs to research outputs while there is a huge gap between research outputs and commercial benefits in our research which need to be addressed. Scaling-up remains as a great challenge to facilitate industry transformation processes from laboratory to real world applications.
