Mesoscale Acoustics on Soft Matter systems

该项目是欧洲(德国莱比锡大学；法国恩斯卡汉大学)和美国(亚利桑那大学，图森；中佛罗里达大学，奥兰多)之间国际跨学科材料研究合作的一部分。该项目的两个主要目标是：a)(理论上)进一步发展分布式点源方法(DPSM)，并使其最佳地应用于软物质的相敏声学显微镜(PSAM)；b)(实验)在研究中验证和应用所开发的模型和相关技术：i)支撑的合成和生物薄膜(模拟为超声场与界面相遇)，以及ii)胶体系统：胶体生物材料、磁泡、聚合物微球(带有超声造影剂的囊泡)。由此产生的DPSM-PSAM技术将为软物质的机械和结构特性的无损表面和亚表面表征提供领先的平台技术。这项技术将允许更有效和更高效的材料表征。该项目还将促进学生和科学家的研究培训、学习和国际交流。

This project is part of an international interdisciplinary materials research collaboration between Europe (University of Leipzig, Germany; ENS Cahan, France), and the U.S.A (University of Arizona, Tucson; University of Central Florida, Orlando). The two main objectives of this project are: a) (theoretically) further develop the Distributed Point Source Method (DPSM), and adapt it optimally to phase-sensitive acoustic microscopy (PSAM) applications to soft matter, and b) (experimentally) verify and apply the developed model and associated technology in investigating: i) supported synthetic and biological thin films, (modeled as ultrasonic field encountering an interface), and ii) colloidal systems: colloidal biomaterial, magneto-vesicles, polymeric micro-spheres (vesicles with ultrasound contrast agents). The resulting DPSM-PSAM technology would provide a leading platform technique for nondestructive surface and subsurface characterization of soft matter mechanical and structural properties. The technology would allow for more effective and efficient materials characterization. The project will also promote research training, learning and international exchange of students and scientists.
