Title: Highly Efficient Synthesis of Helical Carbon Nanocoils and Their Applications

Abstract: 

Due to their specular 3D helical morphology, carbon nanocoils (CNCs) have superior electromechanical properties to the other carbon materials, which show potential applications in supercapacitors, microwave absorption materials, near-infrared detectors, elastic composites, and sensors.

In this presentation, we report the high-yield, high-purity and large quantity synthesis of CNCs and their growth mechanism, which are the foundation of the CNC composites and their applications. It is found that the super elastic CNCs and their composites are excellent sensing mediums, which can be used in multi-functional strain-temperature-humidity sensing, glucose sensing, and infrared sensing. Meanwhile, CNCs can easily form a three-dimensional framework to construct hierarchical porous structures with the other materials, which is suitable for high efficient electrodes of supercapacitors and batteries. Furthermore, CNCs are also excellent fillers for microwave absorbers because of their moderate conductivity, chirality and multiple-loss mechanisms.

Title: Propagation Prediction Based on Physical Optics

Abstract:

Physical optics (PO) or Fresnel-Kirchhoff theory forms the base to solve the problem of diffraction over terrain or buildings, particularly when the terrain or buildings can be modeled as knife edges. Because the numerical integration required to solve the realistic problems is very time-consuming, physical optics is not commonly used in the original formulations for developing the related software products. In order to increase the computational efficiency, a number of assumptions and simplifications have been made. In this presentation, Fresnel-Kirchhoff theory is briefly reviewed, the assumptions and simplifications made for improving the computational efficiency is explained and clarified, the software performance is analyzed through the comparison between prediction and measurement, the inherent drawbacks of the software and its limitations in application are discussed, and possible improvement of the prediction algorithm and procedure is proposed.
