Really, really small, but very, very strong: this sums up the very specific advanced material that scientists led by IAS Senior Fellow Professor Jian Lu at CityU have created.

5月4日出版的《自然》紙質版雜誌的封面主題是“POWERFUL ALLOY”（“超強合金”），這是一項由香港城市大學副校長、香港城市大學深圳研究院院長、先進結構材料研究中心主任呂堅率領的科研團隊取得的科研成果。這也是近年來，中國研究單位在物理、材料科學等領域的成果首次被選為這本權威科學期刊的封面故事。

2017年5月4日，國際頂尖的科學學術期刊《自然》發表了一篇題為“雙相納米結構鑄就最強鎂合金”的封面文章，這是中國結構材料界本世紀首次在《自然》雜誌上發表封面文章，引發業界廣泛關注。新材料線上®第一時間對論文通訊作者，法國國家技術科學院院士、香港城市大學副校長呂堅進行了獨家專訪。

The cover of Nature (4 May 2017, Volume 545, Number 7652) shows the microstructure of an exceptionally strong thin-film magnesium alloy captured using transmission electron microscopy. Produced by dual-phase nanostructuring, this alloy has a strength that approaches the ideal theoretical limit. Nanostructuring of crystalline metal alloys can yield high-strength materials, but these tend to soften as the strain is increased. In this latest work, IAS Senior Fellow Professor Jian Lu and his team combine the benefits of nanocrystallinity with those of single-phase amorphous metallic glasses to yield a dual-phase material --- MgCu₂ nanocrystalline grains (6 nm) enclosed in an amorphous glassy shell (2 nm) --- that resulted in the strongest thin-film magnesium alloy to be made so far.

香港城市大學（城大）團隊最近在材料研究取得重大突破，成功研製全球首創的超納鎂合金材料。這類尖端新型材料的強度較現有超強鎂合金晶體材料高出十倍，變形能力較鎂基金屬玻璃高兩倍，並可發展成生物降解植入材料。

A research team at City University of Hong Kong (CityU) has achieved a ground-breaking advancement in materials research by successfully developing the first-ever supra-nano magnesium alloy.

The French government has bestowed the Chevalier de la Légion d’Honneur on Professor Jian Lu, Vice-President (Research and Technology) (VPRT) and Dean of Graduate Studies at City University of Hong Kong (CityU) since November 2013.
The Légion d’Honneur is the highest national order led by the President of France who services as grand master of the order.

香港城市大學（城大）副校長（研究及科技）兼研究生院院長呂堅教授榮獲法國政府授予國家榮譽軍團勳章（騎士勳位）。國家榮譽軍團勳章是法國總統頒授的最高級別國家勳章。
