He has served board member and the treasurer of Laser Institute of America (LIA). He is now the President of LIA. He has served as chairs and general chairs for numerous international conferences including the general congress chair for International Congress of Applications of Lasers and Electro-Optics in 2007 and 2008. His recent work has been featured by Science 360 and 2011 International Science and Engineering Visualization Challenge joint organized by Science magazine and NSF. 报告摘要：
由于激光能够提供多变且独特的能量源，因此在精确控制材料生长与成形方面有独到优势，并得到了广泛的工业应用。例如，激光材料加工技术已经在材料科学、电子学、国防等领域证明其重要性。在本次讲座中，陆永枫教授主要介绍空气中利用光谱及空间技术调控激光物质相互作用，实现纳米结构功能材料的增材制造。具体内容包括：金刚石薄膜和晶体的快速生长，碳纳米管的自校准生长，在绝缘体表面直接形成石墨烯薄膜层，碳纳米洋葱的合成及其在能量存储和摩擦力学中的应用，以及使用激光辅助光谱和质谱分析法进行核分析鉴定等方向的科研成果。同时，陆永枫教授还将介绍前体分子的震动模式在材料合成中起到关键作用这一新的科研发现，由此推断出温度并非是化学热催化过程的唯一参数。 Abstract:
Since versatile laser sources provide flexible and unique energy sources for precise control of material processing spectrally and specially，different industrial technologies such as laser materials processing have been developed and have demonstrated their significance in many areas such as material science, electronics, defense, and mechanics, In this presentation, the speaker will introduce their research activities in spectrally and spatially controlled laser-material interactions for fast growth of diamond films and crystals in open air, self-aligned growth of carbon nanotubes, formation of wafer-size graphene layer directly on dielectric surfaces, directly writing of nanoscale graphene patterns, synthesis of carbon-nanoonions and their applications in energy storage and triobology, and nuclear forensics using laser-assisted optical spectroscopy and mass spectrometry. The speaker will also introduce their recent discovery that vibrational modes of precursor molecules play important roles in material synthesis, leading to an assumption that temperature may not be the unique parameter governing thermally drive chemical processes. |
