报告介绍 Scanning probe microscopy and optics are the workhorses in various research fields including condensed matter physics and surface science. In this talk, I will introduce you our research effort to combine the two powerful, yet complementary, experimental tools. First, by showing you a few examples that use the two tools respectively, I will tell you, and hopefully convince you the necessity and impo...

报告介绍 Photoisomerization or photodissociation often involves the passage of the excited molecule through a conical intersection between two potential energy surfaces, a process that is important in isolated molecules as well as those in solution. High resolution studies of the dissociation of isolated ammonia molecules prepared with specific vibrations in an electronically excited state show that initial ...

报告介绍 With the development of modern laser technology, nonlinear optics has become an increasingly prominent field in recent decades. It serves as unique characterization tools of many systems that are difficult to access by other means, including surfaces and interfaces of insulating materials, soft matters, etc, making substantial contributions to related fields. Meanwhile, the discovery and synthesis o...

报告介绍 Non-invasive molecular imaging opens a window into the biology of living subject, and its success is critically dependent on the development of chemical probes to enable direct visualization of specific molecular targets and processes. This talk will highlight some of our efforts in building these molecules. The first example involves the design and synthesis of fluorogenic substrates for imaging th...

报告介绍 Beyond its biological interests, DNA is an excellent building block in material science and nanotechnology due to its unique molecular recognition capability and well-defined physical and chemical properties. Using DNA as information-rich construction material, it's feasible to engineer various static DNA nanostructures and dynamic DNA devices via programmed self-assembly. In this seminar, I will di...
