PhD and Master candidates are needed in the following topics:
1. Light scattering and optical manipulation of anisotropic particles by vector Bessel beams;
Introduction: Compared to the traditional micro manipulation technique based on the Gaussian beam, the micro-manipulation technique based on a vector Bessel beam can achieves a higher efficiency and stability. Different from the isotropic particles, anisotropic particles in the potential well demonstrates several brand new features dates back to its properties of anisotropy. The analysis of scattering properties as well as physical mechanism between a vector Bessel beam and anisotropic particles will provide a significant theoretical support and practical guidance for related technologies, including particle characteristics, particle diagnosis and micro-manipulation technology.
2. Optical characterization of droplets: size, temperature, composition, structure
Introduction: Optical diagnostic techniques, including Digital Holography (DH), Rainbow Refractermetry, Interferometric Particle Imaging (IPI), and others, are attractive technologies in the detection and recognization of droplets due to the advantages that they are able to realize a non-invasive, non-damage and real-time analysis.
3. Optical characterization of nanoparticles
Nanomaterials are a new generation of materials composed of nanoparticles with sizes between atoms and macro particles. Nanoparticles presents many special properties different from the bulk macro material. The research on the properties of nano materials has become a hot spot and strategic highland of scientific research in the current international research. The particle size and shape parameters of nanoparticles play a key role in their physicochemical properties and their application in specific fields. How to accurately characterize the parameters of nano materials is a key common problem in the research of nano material properties.
The applicant will focus on the topic "Characterization of nanoparticles based on ultrafast dynamic light scattering imaging method". Based on the translation-rotation ultrafast image dynamic light scattering method, the optical characterization platform of nanoparticle material parameters will be built, and an accurate, fast and economical characterization method of nanoparticle parameters will be developed, which provides a new feasible solution to the key problem of nanoparticle characterization. The expected results will be useful in various fields, such as nano electronic devices, medicine, aerospace, aviation and space exploration, environment and energy.
