卫远,男,系北京化工大学材料科学与工程学院2011级材料科学与工程专业本科生,于2014年通过北京化工大学材料科学与工程学院的“3+2”计划被选派至美国凯斯西储大学进行联合培养。2016年8月至今,在美国凯斯西储大学攻读博士学位。
卫远博士通过利用中子散射技术在聚合物合成方面创造了新的氘标记、聚合物接枝的二氧化硅纳米颗粒的专业合成技术:结合小角中子散射和中子自旋回波谱,测量了纳米颗粒的结构和弛豫动力学, 开启了聚合物接枝纳米粒子的局部弛豫动力学测量和研究的先河,相关研究仍在继续,以确定接枝聚合物中的新“呼吸模式”,研究结果将有助于增强对聚合物纳米复合材料的力学性能和能量耗散能力的理解。由于研究成果突出,卫远博士被凯斯西储大学校友会授予了2019-2020年度的Jack L. Koenig教授荣誉光谱学奖,该奖项每年表彰大分子工程领域的优秀研究生。卫远博士的指导老师Mike Hore表示,为了解决这个问题他付出了令人难以置信的努力,这需要大量的化学合成以及先进的中子散射技术的应用。他评价到:“这不是一个容易的实验,我们为他所取得的成就感到格外自豪。”
Professor Jack L. Koenig Endowed Spectroscopy Award 于1998年在凯斯西储大学校友会设立,由Jack Koenig的朋友、学生和同事创立。Jack Koenig是凯斯西储大学大分子科学与工程系的创始教员之一,其在聚合物光谱学(特别是红外、拉曼和核磁共振)领域成果突出,于2000年被选入美国国家工程院,以表彰他的诸多成就。
Yuan Wei receives Professor Jack L. Koenig Endowed Spectroscopy Award PUBLISHED ON APR. 5, 2020.Yuan Wei, a PhD student in the Department of Macromolecular Science and Engineering, was awarded the Professor Jack L. Koenig Endowed Spectroscopy Award for 2019-2020 by the Case Alumni Association. The award annually recognizes an outstanding graduate student in the department of macromolecular engineering.
Yuan was recognized for his multidisplanary skill in polymer synthesis to create novel deuterium-labeled, polymer-grafted SiO2 nanoparticles with neutron scattering techniques. Specifically, he measured their structure and relaxation dynamics using a combination of **all-angle neutron scattering and neutron spin echo spectroscopy. He is the first in the world to measure the local relaxation dynamics of polymer grafted nanoparticles, and is currently working on follow-up studies to identify novel “breathing modes” in the grafted polymers – the result of which may lead to an deep understanding of the mechanical properties and energy dissipation abilities of polymer nanocomposites.
“Yuan worked very hard to solve this problem, which required a lot of chemical synthesis as well as the application of advanced neutron scattering techniques, remarked Mike Hore, Assistant Professor in the Department Macromolecular Science and Engineering and Wei’s thesis advisor. “This was not an easy experiment, and we are extraordinarily proud of what he has accomplished.”
The prize was established at the Case Alumni Association in 1998 by the friends, students and colleagues of Jack Koenig, a founding faculty member of the department. Koenig distinguished himself in the area of polymer spectroscopy (in particular IR, Raman and NMR), and was elected to the National Academy of Engineering in 2000 in recognition of his many accomplishments.
