Learning from nature and based on lotus leaves and fish scale, we developed super-wettability system: superhydrophobic, superoleophobic, superhydrophilic, superoleophilic surfaces in air and superoleophobic, superareophobic, superoleophilic, superareophilic surfaces under water [1]. Further, we fabricated artificial materials with smart switchable super-wettability [2], i.e., nature-inspired binary cooperative complementary nanomaterials (BCCNMs) that consisting of two components with entirely opposite physiochemical properties at the nanoscale, are presented as a novel concept for the building of promising materials [3-4]. The smart super-wettability system has great applications in various fields, such as self-cleaning glasses, water/oil separation, anti-biofouling interfaces, and water collection system [5]. The concept of BCCNMs was further extended into 1D system. Energy conversion systems that based on artificial ion channels have been fabricated [6]. Also, we discovered the spider silk’s and cactus's amazing water collection and transportation capability [7], and based on these nature systems, artificial water collection fibers and oil/water separation system have been designed successfully [8]. Learning from nature, the constructed smart multiscale interfacial materials system not only has new applications, but also presents new knowledge: Super wettability based chemistry including basic chemical reactions, crystallization, nanofabrication arrays such as small molecule, polymer, nanoparticles, and so on [9].

School of Chemical Engineering, The University of Adelaide, SA 5005, Australia School of Material Engineering and Science, Tianjin University, Tianjin 300072, China s.qiao@adelaide.edu.au

Abstract:
Replacement of precious metal catalysts by commercially available alternatives is of great importance among both fundamental and practical catalysis research. Nanostructured carbon-based and transition metal materials have demonstrated promising catalytic properties in a wide range of energy generation/storage applications. Specifically engineering carbon with guest metals/metal-free atoms can improve its catalytic activity for electrochemical oxygen evolution reaction (OER) and hydrogen evolution reaction (HER), thus can be considered as potential substitutes for the expensive Pt/C or IrO2 catalysts in metal-air batteries and water splitting process. In this presentation, I will talk about the synthesis of nonprecious metal and metal free elements-doped graphene, and their application on electrocatalysis [1-6]. The excellent OER and HER performance (high catalytic activity and efficiency) and reliable stability indicate that new materials are promising highly efficient electrocatalysts for clean energy conversion. I will also present some research results of CO2 electrocatalytic reduction conducted in my research group [7,8].

Abstract
Hollow multi-shelled structures (HoMSs) with hollow interior and multiple shells have been recognized as one type of promising material for applications in in energy conversion and storage, sensors, catalysis, electromagnetic absorption and drug delivery, etc.[1-3, 18] However, compared to their single- shelled counterparts, the synthesis of HoMSs is much more challenging due to the increased complexity of the structure. Our group proposed a general and widely usable sequential templating approach (STA) to prepare HoMSs by utilizing carbonaceous spheres as templates to adsorb metal ions and heating them to remove the template and generate multiple shells[4,5] . Numerous HoMSs of single metal oxides (such as α-Fe2O3, [4,6] ZnO, [7] Co3O4, [8] SnO2, [9] TiO2, [10, 20] Mn2O3 [11] and V2O5 [12]), metal sulfides (Ni3S2, NiS, NiS2) [13], binary metal oxides ((Co2/3Mn1/3)(Co5/6Mn1/6)2O4) [14] and also heterogeneous mixed metal oxides (ZnO@ZnO/ZnFe2O4@ ZnO/ZnFe2O4) [4] have been successfully prepared using STA. The concentration and radial distribution of metal ions can be adjusted by changing the corresponding experimental conditions, such as the metal salt concentration, the solvent, the adsorption temperature and duration, the heating temperature and rate, and so forth, thus controlling the geometric parameters of HoMSs. The breakthrough of synthetic methodologies for HoMSs also provides opportunities to acquire unique physical or chemical properties and performance in specific applications by manipulating their geometric structures, such as shell numbers, shell thickness, inter-shell space as well as shell composition and morphology. Many successful examples have been well demonstrated in the specific fields, including dye-sensitized solar cells, [7,9] lithium ion batteries, [6,8,10,12] sodium-ion battery,[15] alkaline rechargeable battery,[14,16, 19] photo detector,[17] gas sensors,[4,5] etc.

Abstract
The ever-increasing demands for batteries with high energy densities to power portable electronics with increased power consumption and to advance vehicle electrification and grid energy storage have propelled lithium battery technology to a position of tremendous importance. Nanocarbon, including the carbon nanotubes (CNTs) and graphene, known with many appealing properties, have been investigated intensely for improving the performance of lithium batteries. However, a general and objective understanding of their actual role in lithium batteries is lacking. It is recognized that CNTs and graphene are not appropriate active lithium storage materials but are more like a regulator: they do not electrochemically react with lithium ions and electrons but serve to regulate the lithium storage behavior of a specific electroactive material and promote the functional applications of a lithium battery. First, metrics for the evaluation of lithium batteries are discussed, based on which the regulating role of CNTs and graphene in lithium batteries is comprehensively considered from fundamental electrochemical reactions to electrode structure and integral cell design. Finally, perspectives on how CNTs and graphene can further contribute to the development of lithium batteries are presented.

Abstract
Cancer immunotherapy has attracted tremendous attention in recent years. In our recent studies, by employing biomaterials as well as nanoscale delivery systems, we are able to enhance cancer immunotherapy via developing novel nano-vaccines, modulating tumor microenvironment, and achieving combinational immunotherapy, as evidenced by various animal model experiments. In particular, we have demonstrated that local tumor treatment via phototherapy or radiotherapy with rationally designed biomaterials is able to trigger systemic immune responses, which with the help of immune checkpoint blockade therapy would be able to inhibit tumor metastasis and prevent tumor recurrence. In this presentation, I would introduce our latest efforts in this exciting research direction.

Rational electrode design principles beyond li ion batteries

Palladium-copper (PdCu) alloys have two representative crystal structures; one is body-centered cubic (bcc), the other is face-centered cubic (fcc) even though both Pd and Cu originally have fcc crystal. The fcc PdCu alloys have disordered structure within which Pd and Cu have solid-solution in fcc lattice, whereas the bcc PdCu alloys have ordered structure which consists of alternative layers with either Pd or Cu atoms. In particular, bcc PdCu alloys have occasionally shown superior performance to fcc PdCu alloys since the unique ordered structure of bcc has isolated Pd on the surface. Most of bcc PdCu alloys have been synthesized for structural transformation by annealing or seed-growth method of fcc PdCu alloys with inevitable grain growth, uneven surface structure and particle size distribution. Despite these limitations, the Pd on the bcc surface which is provided charge flow from Cu serves as an active site for catalytic reaction, which is highly favorable for lithiumoxygen battery. However, the same size of fcc and bcc PdCu alloys is quite difficult to be obtained since the crystallites larger than 20 nm favor the ordered bcc structure with lower symmetry. Thus, bcc PdCu alloys in nanoscale have been rarely reported, consequently fcc and bcc PdCu nanoparticles (NPs) have never been properly compared until now. In this study, we successfully synthesize fcc and bcc PdCu alloys in nanoscale through precisely adjusting the driving force for reducing organometallic complex. The bcc PdCu NPs with higher surface energy govern the growth thermodynamics of discharge product and greatly improved battery performance based on density functional theory calculation and experimental proof. This study provides critical descriptor on material design in the perspective of modulating surface structure via crystal structure to tune its intrinsic properties.

Exceptional Li storage in nanostructured materials for next generation Li rechargeable batteries

Lithium ion batteries (LIBs) are a key-enabling technology for addressing the power and energy demands of electric vehicles and stationary electrical storage for renewable energy as well as mobile electronics.[1] However, the energy density of currently commercialized LIBs is already close to its technological limit as it is restricted to the conventional reaction mechanisms such as insertion, conversion, and alloying reactions.[2] In this situation, exploring new reaction mechanism and related novel electrode materials can be critical for pushing current battery technology to a next level. Herein, we introduce a novel reaction with a new Co(OH)2 material which exhibits an initial charge capacity of 1,112 mAh g-1 , about twice its theoretical value based on known conventional conversion reaction, and retains its first cycle capacity after 30 cycles. For understanding the origin of anomalously high capacity beyond the theoretical value for the conversion reaction as well as detailed lithium storage mechanism, we conducted synchrotron XRD and XAS, AIMD simulation, localized STEM and XPS measurements. These results will provide novel insight for possible lithium storage mechanisms for nanostructured anode materials, and thus enable the innovative design of electrode materials for next generation LIBs. Additionally, we will present detailed results for mesoporous SnO2 and MoO2 anode materials that show anomalously higher capacity than their theoretical limit, at the time of meeting.

ziqi.sun@qut.edu.au

Abstract Unique structures and functions for plants and animals, which come very close to perfection to suit their specific living environments, have been evolved to suit their environment. Inspired by these interesting properties in nature, researchers have endeavoured to discover novel biological structures and functions and to develop novel artificial bio-inspired materials. In this study, we introduce a novel approach to achieve structure/function mimicking inorganic nanomaterials by designing architecturedefined complex nanostructures by learning from targeted natural species. For example, bio-inspired ZnO nanostructures with designed wetting behaviors have been successfully fabricated by mimicking the natural photonic structures found in the cycloid scales of Asian Arowana (Scleropages) and the compound eyes of horse-flies (Hybomitra micans).

Crystal domain battery materials

For the rapid development of modern society, high-energy storage devices are in demand. Actually in the past 30 years, many kinds of energy storage devices, such as lithium-ion batteries, sodium-ion batteries and so on, have been developed. However, most of the commercially active electrode materials still cannot support the demand of society. Research efforts on higher specific energy density and long cycle life alternative materials are mainly focused on element doping or surface modification. Electrode materials through introducing structure units have been attracted great attentions in recent years. Herein, some important scientific points focusing on crystal domain materials design for better electrochemical performance, reveal and distinction of crystal domain structures based on average and local structure analysis methods, and understanding the relationship between these interior crystal domains and their electrochemical performance, will be discussed.

Abstract
To reduce our dependence on fuel oil and green gas emission, the search for the high figure of merit (ZT) thermoelectric materials have been carried out extensively to convert waste heat into useful electricity. Metal chalcogenides (such as GeTe, SnSe, Cu2Se, and Bi2Te3), as ideal thermoelectric candidates for room temperature and intermediate temperature applications, have been considered the most important thermoelectric materials in this field and show great potential on thermoelectrics. However, further improve their thermoelectric performance have been a current global research focus, which needs innovative strategies. In this presentation, through employing bandgap engineering and nanostructural engineering, we summaries our recent findings on a range of metal chalcogenides with improved thermoelectric properties and their applications in energy conversion generators and medical devices [1-17].

Composite Yttrium-Carbonaceous Spheres Templated Multi-Shell Hollow Spheres with Enhanced Photoluminescence

Keywords: Multi-Shell, Hollow Sphere, Photoluminescence.

Nanosized upconversion (UC) luminescent materials are conspicuous because they are highly suitable for use as alternatives to quantum dots and organic fluorescent dyes for various biological applications including biological imaging, clinical diagnosis, detection, and photodynamic therapy.[1-5] But one crucial limitation of nanosized UC crystals is their low conversion efficiency. In order to overcome this obstacle, a series of approaches have been attempted, including develop of special nano/microstructures to minimize surface quenching.[6] Among various special structure types, hollow-shell spheres are the promising candidate for future luminescent materials. In addition to the well-known features of low effective density and high packing densities, hollow-shelled rare-earth ions doped luminescent materials possess the prominent characteristic of multiple nano/micro-sized inner structures with multiple reflections of light, which would much benefit their luminescent property. As for the synthesis of multi-shell hollow spheres, it is far more challenging to synthesize complex oxides hollow spheres. It is thus highly desirable to develop a novel and general synthetic protocol for the synthesis of high-quality hollow spheres with both controlled multi-shells and multi-components as well. Our group started the research on rare earth metal oxides system and successfully synthesized simple oxides CeO2 multishell hollow spheres.[7,8] However, rather few previous research has stepped into complex oxides multi-shell hollow spheres. Herein, we report a novel synthetic strategy for complex oxide multi-shell hollow spheres. Through the hydrothermal route, the composite yttrium-carbonaceous spheres (YCSs) can be obtained in large quantity, which with hydrophilic functional groups are further employed as the hard template for the adsorption of VO3− anion. And then, the complex oxide YVO4 multi-shell hollow spheres with uniform morphology, high crystallinity, and controlled shell numbers up to the triple could be successfully synthesized under the programmed thermal annealing. Moreover, with doping of Yb3+ and Er3+ , the as-synthesized phosphors can offer much enhanced UC luminescence properties comparing with the reference. The UC luminescent intensity increases with the shell number increasing.

About the Speaker

Ranbo Yu’s current research interests are the design and synthesis of mesoscopic structured materials with "self-supporting", multiple levels and composites. Due to the high effective surface area, and rapid mass transport and energy transfer the construction of these materials may lead to enhanced chemical and physical properties. I have devoted a majority of my time to development of several methods to synthesize metal oxide multiple-shell hollow spheres and for the self-assembly of inorganic nanoparticles. Hierarchically ordered structures and mesoscopic composites have also been created by translating the knowledge obtained in the above studies. More efforts are paying to the exploration of the physical-chemical property of the synthesized materials.
