This NSERC Discovery program builds on five years of fundamental research and technological developments supported by NSERC-DG, NSERC-CRD, NSERC-I2I, OCE-VIP2 and other funding programs. The long-term goal of my research program lies in the investigation of dynamical phenomena and structure-function correlations relevant to the fields of condensed matter physics, solution chemistry, and molecular biology. To achieve this goal, my team implements homebuilt femtosecond (fs) spectroscopic and electron imaging methods that are capable of providing us with the prerequisite temporal and spatial resolutions to observe atoms in motion; i.e. sub-picosecond temporal and ångstrom spatial resolutions. I lead the Ultrafast electron Imaging Lab (UeIL); I highly motivated and interdisciplinary team with research topics ranging from the study of carrier dynamics, electron-phonon and phonon-phonon interactions, excitons, and laser-induced phase transformations in crystalline low dimensional materials to excited state dynamics and electron transfer reactions between molecular species in the liquid phase. My group also utilizes molecular dynamics simulations and electronic structure calculations to assist our experimental observations. UeIL hosts unique homebuilt infrastructure for the dynamic characterization of molecular structure and materials properties. The objectives of this Discovery proposal are a logical continuation of my research with a focus on the application of time-resolved techniques to the investigation of nanomaterials, thin films and molecular species; special attention will be paid to model two-dimensional van der Waals-stacked materials exhibiting exotic behaviours such as charge density wave, topological insulation, ferromagnetism and Weyl semi-metallicity. In addition to the aforementioned time-resolved experiments, a new and quickly growing research direction at UeIL involves the study of nanoparticles and biospecimens by in-liquid transmission electron microscopy (in-liquid TEM) and cryogenic-TEM (cryo-TEM). My team has developed our own specialized side-entry TEM holders and established collaborations with world leading experts in these research areas. Three of our technologies have been patented via Waterloo Commercialization Office and the creation of a spinoff by senior group member is anticipated, ca. 2021. My intention is two-fold; to enable unique impactful research results through technology innovation and to bring to the market state-of-the-art devices that will drive further expansion of both, the startup and my own laboratory. My team is about to enter a very exciting and productive phase in which UeIL's state-of-the-art instrumentation will drive the generation impactful research results, the establishment of a multitude of interdisciplinary collaborations, and open the doors to new discoveries.

该NSERC发现计划基于NSERC-DG，NSERC-CRD，NSERC-I2I，OCE-VIP2和其他资金计划的五年基础研究和技术发展。我的研究计划的长期目标在于动态现象的投资和结构 - 功能相关性与凝聚物物理，溶液化学和分子生物学领域有关。为了实现这一目标，我的团队实施了自制的飞秒（FS）光谱和电子成像方法，这些方法能够为我们提供先决条件的临时和空间分辨率，以观察运动中的原子；即临时和Ångstrom空间分辨率。我领导超快电子成像实验室（UEIL）；我具有较高的动力和跨学科团队，研究主题从载体动力学，电子 - 波和声子 - 波相互作用，激发子以及激光诱导的相位相变的相位转换到液体相位液相的激发态动力学和电子转移反应之间的激光诱导的相变的研究主题。我的小组还利用分子动力学模拟和电子结构计算来帮助我们的实验观察。 UEIL拥有独特的本地基础设施，用于分子结构和材料特性的动态表征。这项发现提案的对象是我的研究的逻辑延续，重点是应用时间分辨技术在研究纳米材料，薄膜和分子物种中的应用。将特别关注二维范德华堆积物材料的模型外来行为，例如电荷密度波，拓扑隔热，铁磁性和Weyl Semi-Metallicity。除了近似时间分辨的实验外，UEIL的新的，快速增长的研究方向还涉及通过液体透射透射电子显微镜（液体液体TEM）和低温TEM（Cryo-Tem（Cryo-TEM））研究纳米颗粒和生物膜的研究。我的团队已经开发了我们自己的专业辅助入口持有人，并与这些研究领域的世界领先专家建立了合作。我们的三项技术已通过滑铁卢商业化办公室获得了专利，预计将由高级小组成员创建衍生。 2021年。我的意图是两个方面；通过技术创新来实现独特的有影响力的研究结果，并为市场最先进的设备带来，这将推动这两者的进一步扩展，初创企业和我自己的实验室。我的团队即将进入一个非常令人兴奋和富有成效的阶段，在该阶段中，UEIL的最新工具将推动一代有影响力的研究结果，建立多种跨学科合作，并为新发现打开大门。
