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》纸质版杂志的封面主题是“POWERFUL ALLOY”（“超强合金”），这是一项由香港城市大学副校长、香港城市大学深圳研究院院长、先进结构材料研究中心主任吕坚率领的科研团队取得的科研成果。这也是近年来，中国研究单位在物理、材料科学等领域的成果首次被选为这本权威科学期刊的封面故事。

2017年5月4日，国际顶尖的科学学术期刊《自然》发表了一篇题为“双相纳米结构铸就最强镁合金”的封面文章，这是中国结构材料界本世纪首次在《自然》杂志上发表封面文章，引发业界广泛关注。新材料线上®第一时间对论文通讯作者，法国国家技术科学院院士、香港城市大学副校长吕坚进行了独家专访。

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.

香港城市大学（城大）团队最近在材料研究取得重大突破，成功研制全球首创的超纳镁合金材料。这类尖端新型材料的强度较现有超强镁合金晶体材料高出十倍，变形能力较镁基金属玻璃高两倍，并可发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.

香港城市大学（城大）副校长（研究及科技）兼研究生院院长吕坚教授荣获法国政府授予国家荣誉军团勋章（骑士勋位）。国家荣誉军团勋章是法国总统颁授的最高级别国家勋章。
