Speech Title: Recent progress of acoustic tomography on noninvasive temperature and velocity measurement

Abstract: As a constituent of the industrial process tomography, acoustic tomography (AT) has emerged as a promising method for high-fidelity measurement of temperature and velocity fields, and is extensively employed in multiphase flow measurement techniques such as flow monitoring and combustion diagnostic. However, subjected to safety and reliability requirement of furnace, the number of installed transducers is restricted. This leads to a sparsity of valid data, which in turn results in the ill-posedness and rank-deficiency of limited-data AT. Therefore, special attention should be paid on acquisition of accurate time of flight (TOF) data and development of efficient reconstruction algorithm. In this work, we present a comprehensive review of the recent advancements made by our group in addressing the AT problem.

The intricate furnace environment, particularly the significant temperature gradient within, will affect the transmission of sound waves. According to Fermat’s principle of stationary time, path that wave travels is the one that takes the least time. Inhomogeneous temperature profile in region of interest will lead to velocity changes of sound wave, and thus the acoustic refraction effect. In large temperature gradient and low velocity magnitude situation, considering acoustic refraction effect, we utilized combined meshfree radial basis function and alternating direction method of multipliers to reconstruct temperature and velocity fields simultaneously. 

However, there are some cases that the magnitude of flow speed is more than 100 m/s, and even approach to a couple of Mach. The flow speed cannot be ignored compared with the sonic speed. TOF with respect to temperature and velocity fields is nonlinear. Therefore, the covariance matrix adaptation evolution strategy algorithm is introduced to solve the nonlinear AT (NAT) inverse problem. In addition, the selection strategies of temperature and velocity regularization parameters are given.

To further guarantee the quasi real-time reconstruction and alleviate ill-posedness of NAT problem, this problem is transformed to be a many-objective optimization problem with four objectives. Knee point-driven evolutionary algorithm with improved environmental selection strategy is proposed to reconstruct the arbitrary inhomogeneous temperature and aerodynamic fields in furnace simultaneously.

Actually, transducers arrangement will also affect the reconstruction accuracy. Based on the prior information that linear independence of vectors incorporates maximum measurement information, linear independence degree metric is proposed to optimize transducer arrays arrangement. It contains no prior information about flow velocity fields, which make the procedure perform in an off-line mode.

In conclusion, the proposed methods for multiphase flow measurement provide valuable guidance for the development of non-intrusive, real-time pyrometry and velocimetry systems, capable of accurately measuring a wide range of velocity magnitudes and temperature gradients. The potential of these methods in complex combustion and flow diagnostic applications is expected to greatly benefit energy conservation, emission reduction, and optimization of combustion processes.

Speech Title: Biomimetic peptide self-assembly for functional materials and novel applications

Abstract: The unique biological and physical properties of metabolites inspired fruitful studies of supramolecular assembly and their conjugates as engineering materials, and the discovery of piezoelectric peptide nanostructures enables the fundamental study of electromechanical characteristics and many practical applications. Randomly oriented polarizations of peptide nanostructures have severely limited their piezoelectric performance, while peptide assemblies with uniform polarization are essential for fundamental study and device fabrication. We have combined computational and experimental investigation and uncovered many piezoelectric biomaterials from amino acids and peptides. We discovered that applying an electric field to synthesize an ordered diphenylalanine (FF) array produced a uniformly polarized vertical array. Then we studied the effect of electric fields on the peptide self-assembled structures and achieved laterally aligned peptide arrays. Our computation showed that the piezoelectric peptide assemblies should outperform the conventional piezoelectric ceramics in an energy conversion device, and we then explored the peptide's energy harvesting potential. We fabricated peptide-based nanogenerators, hybrid nanogenerators, and flexible nanogenerators and explored their degradation behavior in different solutions. The self-assembled peptide structures are expected to expand the landscape of bio-inspired and environmentally friendly functional materials and enable new energy and sensing technology to improve health and quality of life.

Speech Title: Ceramic-Polymer Composites Prepared via Cold Sintering Process

Abstract: Ceramicpolymer composites have attracted much attention due to the excellent combined physical and chemical properties. However, most of the ceramics are sintered at high temperatures, typically higher than 1000 ºC, which are not compatible with the processing temperatures of polymers. Thus, it is challenging to integrate ceramics with polymers in a onestep sintering process. Cold sintering process proposed in 2016 provides a route for the densification of ceramics at temperatures lower than 350 ºC. The low sintering temperature makes it possible to cosinter polymers, nanoparticles, and 2Dmaterials with ceramics in a simple process. A wide variety of electronic materials have been demonstrated to be cold sintered at temperatures lower than 350 ºC. This talk will discuss the recent development of cold sintered electronic materials based on ceramic-polymer composites.
