Title of Speech: Membrane concepts for gas separations 

Abstract: Membranes with high CO2 permeance are of great interest for the capture of greenhouse gases and natural gas purification. Our research originally focused on few-layered selective skin layers of graphene oxide (GO) supported on commercial ultrafiltration membrane substrates to create CO2-selective channels by interspersing the layers with CO2-philic compounds [Energy & Environ. Sci. 9 (2016) 3107-3112; Angew. Chem. Int. Ed. 56 (2017) 14246-14251]. These interlayer compounds serve (1) as crosslinkers and molecular spacers to stabilize and control the d-spacing, (2) to create a chemical environment, and (3) to create a ‘water’ environment. Now, metal-induced ordered microporous polymers (MMPs) are reported as a new class of materials derived from functional polymers, small organic linkers and divalent metal ions [Nat. Mater. 18 (2019) 163-168]. MMPs are 3D self-assembled nanoparticles in the range of 50-100 nm, which can simply be coated as dilute dispersions onto modified polysulfone substrates, providing a practical route to prepare large-scale membranes with defect-free ultrathin gas-selective coated layers. CO2 permeances in the range of 3000-5500 GPU and suitable mixed gas CO2/N2 selectivities are obtained, which are promising for meeting DOE CO2 capture targets.
Current research is underway on in situ fabrication of large-area ultra-thin metal organic frameworks on commercial ultrafiltration membrane supports. Further work on covalent organic framework mixed matrix membranes is being conducted.

Title of Speech: Development of porous carbon materials using polymers and its application to greenhouse gas capture 

Abstract: In this talk, recent studies to prepare porous carbons using polymers are introduced.
First, polyvinylidene fluoride (PVDF) was used to develop porous carbons. The carbonized PVDF has been known for exhibiting high surface area and pore volume with highly uniform micropores, which give the potential for high adsorption capacities. The effects of carbonization temperature on the characteristics and greenhouse gas (CO2 and CF4) adsorption behavior of prepared carbon materials were investigated. The PVDF-based porous carbons showed high surface area and pore volume more than 1000 m2/g and 0.4 cm3/g, respectively, and the significant increase of these textural properties was mainly attributed to the development of micropores. The surface area and pore volume could be increased up to 2750 m2/g and 1.465 cm3/g, respectively, with further activation. It is noteworthy that the greenhouse gas adsorption uptake was highly influenced by narrow micropore volume, rather than surface area or total pore volume. The developed PVDF-based porous carbon showed high greenhouse gas adsorption uptake, excellent recyclability, easy regeneration, and rapid adsorption–desorption kinetics.
Second, waste polyethylene terephthalate (PET) plastic bottles were used to prepare environmentally friendly and cost-effective porous carbonss. PET plastic bottles were carbonized and activated to develop porous carbons, and their greenhouse gas adsorption behaviors were investigated from both equilibrium and kinetic perspectives. Varying the activation temperature had a dramatic effect on the textual properties of the prepared carbons. The greenhouse gas adsorption on the PET-derived porous carbons was also mainly related to the pore volumes of narrow micropores. The PET-derived porous carbons not only exhibited high greenhouse gas uptake, but also good selectivity, simple regeneration, excellent cyclic stability, and rapid adsorption-desorption kinetics. The development of porous carbons from waste PET plastic bottles can provide cost-effective and promising greenhouse gas adsorbents, and can also alleviate environmental issues caused by PET plastic waste.

Title of Speech: Inorganic solid electrolytes for all-solid-state lithium batteries 

Abstract: As a typical type of energy storage devices, lithium-ion batteries (LiBs) play a more and more important role in the modern life. However, organic polymer-based electrolytes are widely used in commercial Li-ion batteries, which may cause a large number of safety issues, considering the flammability, electrochemical stability, and leakage. Fires and explosions of LiBs have been reported throughout the world, and thus, safety has become one of the main obstacles for the wide application of LiBs. Therefore, the continued drive for high-performance lithium-ion batteries has imposed stricter requirements on the electrolyte materials and all-solid-state lithium batteries (ASSLiBs) have entered the field. In contrast to organic liquid electrolytes, solid inorganic ones show better thermal and chemical stabilities and also present a great advantage to the point that they can enable the use of high capacity electrode materials. Accordingly, a great deal of effort is underway to improve further the ionic conductivity and electrochemical/chemical stability of inorganic solid electrolytes and the solid electrolyte/electrode interface as well, thereby pushing them further for practical applications. In this talk, I will present our research breakthroughs in studying the preparation, structure, electrochemical properties, and potential applications of several important inorganic solid electrolytes, such as Li-oxide garnets like Li7La3Zr2O12 (LLZO), perovskite-type La2/3−xLi3xTiO3 (LLTO), NASICON-type Li1+xAlxTi2-x(PO4)3 (LATP), and sulfide-based LGPS-type Li10.35Ge1.35P1.65S12.

Title of Speech: Metamaterial-like vibration of mass chain-filled carbon nanotubes 

Abstract: Inspirited by recent literature on metaelastic materials of locally resonant microstructure, vibration of CNTs (carbon nanotubes) filled with mass chains (such as carbon atom-chain or C60 molecule chain) is studied as a potential new kind of metaelastic materials. Our work revealed that a mass chain-filled CNT does exhibit negative effective mass density and an associated "bandgap" within a certain terahertz range of frequencies. Our results clearly confirmed that when the applied exciting frequency falls in the bandgap, forced vibration of the mass chain-filled CNT is highly isolated nearby the site of the applied stimulus and all other parts of the filled CNT remains essentially static. This result predicts that mass chain-filled CNTs could offer a new kind of metaelastic materials and exhibit remarkable vibration isolation in the terahertz range. The results shown here may provide useful insights into vibration controlling of CNT-related materials at terahertz frequencies.

Title of Speech: Hybrid Fiber-Metal Laminates for Lightweight Marine Structural Applications 

Abstract: Steel has certain limitations that impede continued improvements targeted to construct lighter, more resistant and safer marine structures. Composite materials are light and resistant, but the manufacturing processes are more labor-intensive and costly; in addition they are very sensitive to damage from impact and can present problems of degradation of mechanical properties through water absorption, and fire safety issues. Fiber-Metal Laminated (FML) hybrid materials combine a high resistance to impact, an extended durability, and the versatility in processing of metals with a specific strength and stiffness in the direction parallel to the fibers, as well as good resistance to fatigue, characteristics of the composites. In the old art of naval construction only one revolution took place, the step from wood to steel, but perhaps we are in the second revolution, the use of FML materials capable of satisfying all the design and fabrication requirements for lighter structures that are in turn more resistant, permit higher speeds of movement and lower energy consumption. Repair of existing vessels can also be improved with the use of these hybrid materials. In lightweight designs, weight reduction by using hybrid materials will reduce CO2 emission and increase fuel economy, which will significantly reduce environmental impact. A promising area of application is the design of hybrid-towers for wind energy converters (WEC). However, the requirements on the supporting structures will be also increased with the development of bigger turbines, especially in offshore parks. A tower section made of FML materials offers some advantages with regard to the stability and structural integrity of these huge structures floating in the ocean. Reducing construction and operating costs, and keeping the safety standards: these advantages are key factors in selecting FML hybrid materials for lightweight structural marine applications.
