2017年7月5日上午10:30，网赌十大正规网址青年科技工作者协会、世界十大网赌排行榜青年科协联合世界十大网赌排行榜研究生会举办的青年学术沙龙第239场在化学楼210顺利举行，本次报告主讲人为温海明助理教授，世界十大网赌排行榜胡涛教授等师生到场参加。

本次报告的主题为“极端环境下的纳米材料的发展与表征”。具有结构单元的块体纳米材料近年来引起了全世界科学界的密切关注，它属于一种新的范畴内。它们的结构特点是包含着很高体积分数的晶界，这使得与传统的粗晶材料相比，纳米材料的力学与物理性能被显著加强。纳米材料技术的发展赋予了他们能在极端环境下的应用能力，例如中子辐射与弹道冲击。本报告中，温教授主要介绍其在适用中子辐射环境下的纳米材料方面所做的工作。块体纳米核材料可以通过低成本先进制造技术（如等通道挤压）制备而成，使用中子和离子辐射对其进行评估。核材料的结构能够被控制在纳米尺寸内，这样可以达到理想的性质和性能。另外，温教授也介绍了如何去表征这种核材料，以及一种纳米结构的铝合金材料。整场报告话题新颖，师生讨论热烈，取得了很好的效果。
