  目前📸，科學家們在新材料設計和加工戰略和方法的發展方面取得了重大進展。在這裏🥷🏿，我們特別強調了多功能組合的優勢，以實現對材料性能的協同增強效應🤟。包括碳塗層與帶工程相結合以改變電子性能⚁；形貌控製的通用方法；物理約束與催化效應相結合以控製金屬硫電池中多硫化物的損失；多種應變工程用於改進超導體中的通量釘紮和催化劑中的反應位點；用於控製納米材料尺寸😿、形狀和成分等生長的加和減工程；實現優化的電子、離子和光學性能的多維操作🧙🏻；設計蛋黃殼球/核殼結構用於控製不需要的應變🦇；在材料、結構和裝置層面進行交叉🤏🏼，以實現高活性催化劑和存儲材料的製備🤳🏼。無論是在基礎還是應用層面，界面/表面科學和工程是材料設計和加工的最關鍵要素👩‍👩‍👧。我們的大多數研究都局限於研究投入到研究產出的範圍內🉐，而研究產出和商業應用之間存在巨大差距🫄，這也是需要我們重視的問題。在從實驗室到實際應用的工業轉化過程中👨🏼‍🍳🪱，擴大規模達到量產仍然是一大挑戰。

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.
