Title of Speech: Review of Metamaterials: Designed Crystalline Materials with Unusual Properties 

Abstract: Metamaterials are rationally designed artificial materials composed of tailored functional building blocks densely packed into an effective (crystalline) material. While metamaterials historically are primarily thought to be associated with negative refractive indices and invisibility cloaking in electromagnetism or optics, it turns out that the simple metamaterial concept also applies to many other areas of physics namely the thermodynamics, classical mechanics (including elastostatics, acoustics, fluid dynamics and elastodynamics) and in principle also to the quantum mechanics. This lecture will review the basic concepts and analogies behind the thermodynamic, acoustic, elastodynamic/elastostatic, and electromagnetic metamaterials and differences among them. It will provide an overview of the theory, the current state of the art and example applications of various types of metamaterials. The review will also discuss the homogeneous as well as inhomogeneous metamaterial architectures designed by coordinate-transformation-based approaches analogous to transformation optics. The application examples will include laminates, thermal cloaks, thermal concentrators and inverters, anisotropic acoustic metamaterials, acoustic free-space and carpet cloaks, auxetic mechanical metamaterials, pentamode metamaterials (meta-liquid), and mechanical metamaterials with negative dynamic mass density, negative dynamic bulk modulus, or negative phase velocity. Finally an example of quantum-mechanical matter-wave cloaking will be provided.

Title of Speech: Recent Developments on Deformation Twinning in Metallic Materials 

Abstract: Twinning is known to be an important deformation mechanism in crystalline materials like metals and ceramics. Once the twin nucleates, it is normally expected that the growth of twins approaches the speed of sound in the material. However, the author and his coworkers have discovered that this process can occur at speeds many orders of magnitude lower than the speed of sound. This was found to occur both in hexagonal close-packed (HCP) structures as well as in body centered cubic (BCC) structures. More importantly, twinning in titanium alloys has been attributed to control the low temperature (<0.25 Tm) creep deformation. Given that many metallic and ceramic materials exist in HCP and BCC crystalline forms, these findings are expected to be applicable to most of these materials as well. The phenomenon of slow growth of twins has been termed time-dependent twinning. It has been suggested that this process is due to slow diffusion of oxygen atoms that occupy interstitial sites, which are displaced away from the twin/parent matrix grain boundary. In this presentation, the crystallographic and atomistic models for the diffusion of oxygen for time-dependent twinning phenomena will be presented. In addition, the effect of the microstructural parameters, such as grain size, on the time-dependent twinning phenomenon will be discussed. Furthermore, the ramifications of these findings in relation to the processing of existing metallic materials and the development of new alloys will be outlined.

Title of Speech: Bioinspired Electrocatalyst for Solar Fuel 

Abstract: Water splitting is regarded as a promising step towards environmentally sustainable energy schemes because electrolysis produces only hydrogen and oxygen, without any by-products. The oxygen evolution reaction (OER), an anodic half-cell reaction, requires extremely high overpotential due to its slow reaction kinetics. In nature, there exists a water oxidation complex (WOC) in photosystem II (PSII) comprised of the Mn and Ca elements. The WOC in PSII, in the form of a cubical Mn4CaO5 cluster, efficiently catalyzes water oxidation with extremely low overpotential value (~160 mV) and a high turnover frequency (TOF) number (~25,000 mmolO2 mol-1Mn s-1).
We first identified a new crystal structure, Mn3(PO4)2-3H2O, and demonstrated its superior catalytic performance at neutral pH. We revealed that structural flexibility can stabilize Jahn-Teller distorted Mn(III), and thus facilitate Mn redox during catalysis. Additionally, a new pyrophosphate based Mn compound, Li2MnP2O7 was studied. We verified the influence of Mn valency and asymmetric geometry on water oxidation catalysis using Li2MnP2O7 and its derivatives.
Specific questions that our group intensively focus for the further applications include 1) how we can translate the underlying principles in Mn4CaO5 cluster into the synthetic heterogeneous catalysts and 2) how we can mimic the redox molecule involved biological dark reaction for the CO2 reduction. Toward this vision, we have been developing a new catalytic platform based on sub-10 nm uniform nanoparticles to bridge the gap between atomically defined biological catalysts or their metalloenzyme counterparts and the scalable, electrode depositable heterogeneous catalysts. In this approach, the local atomic geometry is controlled by the nitrogen containing graphitic carbon and the heterogeneous atom doping, that enhance the catalytic activity and selectivity. Additional surface modification by the specific ligand allows for the atomic scale tunability to realize the unique electronic hybridization.

Title of Speech: On Fireworks Algorithm Research and Its Application to Material Engineering 

Abstract: Recently, inspired from the collective behaviors of many swarm-based creatures in nature or social phenomena, swarm intelligence (SI) has been received attention and studied extensively, gradually becomes a class of efficiently intelligent optimization methods. Inspired by fireworks explosion at night, the fireworks algorithm (FWA) was developed in 2010. Since then, several improvements and some applications were proposed to improve the efficiency of FWA. In this presentation, the fireworks algorithm is first described in detail and reviewed, then several effective improved fireworks algorithms are highlighted individually. By changing the ways of calculating numbers and amplitudes of sparks in fireworks’ explosion, the improved FWA algorithms become more reasonable and explainable. Extensive experiments on IEEE-CEC’s benchmark functions demonstrate that the improved fireworks algorithms significantly increase the accuracy of found solutions, yet decrease the running time dramatically. Finally, some applications of FWA are briefly described, in particular, the applications of FWA to some important optimization problems happened in material engineering filed are highlighted and reviewed in details. I believe that the FWA will find its right way in the field of material engineering in future.
