Electrochemical Technique for Materials Processing and Manufacturing: Manoj Mahapatra1; Mark King1; 1University of Alabama at Birmingham
Electrochemical technique, a low temperature materials processing method, is gaining renewed interest for corrosion prevention, functional coatings for energy conversion and storage and biomedical applications, and joining of metallic and ceramic components. Recent progress in materials processing by electrochemical method will be reviewed first. Subsequently, role of cyclic voltammetry on identifying the electrochemical parameters for metallic coating deposition on a model substrate will be discussed. We have shown that cyclic voltammetry is quick and effective to determine the suitable deposition parameters compared to Edisonian approach.

Cathode, Anode and Electrolyte for Non-flammable Sodium-ion Cells: Palani Balaya1; 1National University of Singapore
Deployment of micro-grids using renewable energy requires large-scale electrical energy storage (EES) systems. Currently, lithium-ion batteries (LIBs) are leading candidates for EES. High power density LIBs addressing intermittency of renewables are expensive. Besides, lithium is a scarce resource. Sodium, on the other hand, is one of the most abundant elements on the Earth crust. Sodium-ion batteries (NIBs) operating at ambient temperature are expected to be durable, safe and inexpensive. Regardless of the relatively lower energy density, NIBs can effectively be employed in micro-grid applications, where the footprint requirement is not severe.We recently developed a non-flammable sodium-ion conducting glyme based electrolyte displaying excellent storage performance of low voltage anodes as well as high voltage cathodes of sodium-ion cells. We will present our works on rhombohedral Prussian Blue analogoue and sodium vanadium phosphate as cathode and hard carbon as anode using above glyme electrolyte. We will end the talk with a note on the viability of room-temperature rechargeable in-situ sodium plated battery with bare Cu current collector foil as anode, which operates by sodium plating/stripping on Cu foil during each cycle.
A Preliminary Review and Classification of Environmental Life Cycle Impacts
for Various Materials
: John Wolodko1; Ehsan Vaziri Yeganeh1; 1University of Alberta
Over the past decade, there has been an increased interest and focus on sustainable development and design. This interest has corresponded with the development of new methodologies such as Design for Environment and Life Cycle Assessment (LCA). While these approaches are used by specific segments of the design community, there is still a lack of understanding about the potential environmental impacts of various material classes and how this information can be integrated in traditional materials selection processes. This paper provides a preliminary attempt to summarize various environmental impacts for different material classes based on a comprehensive review of the literature. Data is compiled from a number of LCA studies, and are grouped according to material classification and impact factor. From this analysis, guidance is developed which may assist materials engineers to better understand potential impacts and considerations in the selection process.

Development of Ice-templated Sintered Metal Oxides with Directional Porosity and Understanding Structure-mechanical Property Relationships: Dipankar Ghosh1; Rohan Parai1; Sashanka Akurati1; Justine Marin1; 1Old Dominion University
Mechanically robust open-cell porous ceramic materials are important for a variety of engineering applications such as energy storage, bone-tissue engineering, and lightweight structures. However, high pore tortuosity and weak mechanical behavior of conventionally processed open-cell ceramics require alternative fabrication methodologies. Ice-templating is an emerging, environment friendly manufacturing technique that enables the synthesis of hierarchical porous ceramic with directional porosity. This technique relies on the low temperature unidirectional solidification process in which simultaneous phase segregation of solvent (as crystals) and particles occurs. In this presentation, we will discuss our work on the synthesis of ice-templated sintered metal oxides which could be utilized as battery electrodes. We will discuss the role of different processing variables in tailoring length-scale components of hierarchical structure and the corresponding impact on compressive mechanical properties, which will enable to understand the structure-mechanical property relationships. This work has significant implications to utilize ice-templated materials for energy storage applications.

Development of Low Thermal Expansion Cordierite Porcelain Cook Wares: Lalit Sharma1; Kali Singh1; 1CSIR-Central Glass & Ceramic Research Institute
Cook wares are used to keep the eatables in warm condition.Investigations were carried out to develop formulations by using clays, Talc &, Calcined Alumina in different proportions. Transparent glaze of matching Thermal Expansion was developed. Different shapes were developed by using Roller Head Jigger. Shapes were Bisque fired at 1350deg C at soaking period of 4 hrs in Electric Kiln. Glost firing was carried out at 1000 deg C in Electric Kiln. Test bars were taken for further studies of Thermal Expansion, Apparent Porosity, Water Absorption, Thermal Shock and Bulk Density. Developed wares were tested for Thermal Shock for 20nos Cycles from 500 deg C to air quenching. 9% MgO based formulation was found to be best suitable with thermal expansion of 2.09x10-6/deg C. Out of different glaze compositions, fritted glaze was found to be suitable for the body formulations. XRD studies showed good cordierite peaks.
Conductivity Properties of Mg-Al Layer Double Hydroxides: Keiichiro Maegawa1; Qiaxian Johnson2; Mihaela Jitianu2; Atsunori Matsuda1; Andrei Jitianu3; 1Toyohashi University of Technology; 2William Paterson University; 3Lehman College, City University of New York
The Layer Double Hydroxides (LDHs) have been actively studied recently. Due to their anion exchange properties, LDHs are expected to be used for electrochemical applications. Until recently, only the samples obtained by co-precipitation (CP) method have been studied for electrochemical applications. The sol-gel (SG) method is a significant candidate for the synthesis of LDHs with smaller particle size. Here we report a comparative study of Mg-Al LDHs prepared by SG and CP. The crystallinity and the interlayer of the studied samples were enhanced by hydrothermal treatment. The conductivity, structure morphology of the LDH were compared between SG and CP. The interlayer anionic conductivity is higher for the SG samples, being between 199.6 and 245.0 mS/cm2, while for the CP samples this was between 0.39 and 7.32 mS/cm2. The structure of the LDH was investigated by X-Ray and FT-IR analysis. The FT-IR shows the structure of the interlayer ions.
Fabrication and Characterization of Metakaolin-based Geopolymers with and Battery and Construction and Demolition (C&D) Waste Content for Potential Shielding Applications: Raul Florez1; Deiber Riascos2; Carlos Castano1; Henry Colorado2; 1Missouri University of Science and Technology; 2Universidad de Antioquia
In the present study, alkaline battery waste has been processed and combined with construction and demolition waste (CDW) to produce geopolymers with shielding properties against gamma and neutron radiation. This innovative application is aimed to produce an alternative high-value product which can be used at the front end of the nuclear fuel cycle. Different contents of battery waste and CDW were mixed and alkali-activated to produce geopolymer cements. Microstructural and mechanical properties of the as-fabricated composite geopolymers were analyzed via X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Compression testing respectively. Transmission experiments and Monte-Carlo simulations were also performed to evaluate the attenuation properties of the geopolymers against gamma and neutron radiation. The strengths and limitations of this new proof-of concept shielding material are discussed in terms of structural, mechanical and attenuation properties.
Optimization of Torrefaction Parameters for High Energetic Yields: Jamiu Odusote1; Adekunle Adeleke1; Olumuyiwa Lasode1; M Malathi2; Dayanand Paswan3; 1University of Ilorin; 2 CSIR-National Metallurgical Laboratory; 3CSIR-National Metallurgical Laboratory
Torrefaction parameters for Tectona grandis (Melina wood) were optimised using a 2-level full factorial design (FFD) at temperature (240 - 300°C), residence time (30 - 60 min) and particle size (2 - 6 mm). The optimum parameters for high energetic yield obtained were temperature of 260℃, residence time of 60 minutes and 2 mm particle size. Temperature was found to have greatest influence on the combustion properties of the Tectona grandis sample. The results showed that the volatile matters and moisture contents of the raw biomass increased from 79.26 to 54.90% and 7.23 to 2.87%, respectively, while the fixed carbon and HHV increased from 11.73 to 40.43% and 18.73 to 23.10MJ/kg, respectively after torrefaction at optimum conditions. This indicates that the torrefied Tectonas grandis has better energetic yields and thus can be employed in energy generation and metallurgical purposes.

Fractal Nature Bridging the Gap within the Space Scale Nano-microstructures-Meso-mega Sizes: Vojislav Mitic1; Goran Lazovic2; Tsong Perng3; Dusan Milosevic4; Hans Fecht5; Branislav Vlahovic6; 1University Nis, Fac. Electronic Engineering, ITS. S.A.S.A; 2Faculty of Mechanical Engineering University of Belgrade; 3National Tsing Hua University; 4Faculty of Electronic Engineering University Nis; 5University Ulm; 6NCCU, USA
Today in the age of advanced ceramics civilisation and especially within modern ceramics naterials with specific properties there are a variety of applications. Our uptoday research recognize that ceramics have a fractal configuration nature on the basis of different phenomena. The key property of fractals is their independence of the scale. The practical value is that the fractal objects’ interaction and energy is possible at any reasonable scale of magnitude, including nanoscale. This is a consequence of fractal independence on scales. This brings us to the valuable conclusion that properties of fractals are valid on any scale, macro, micro, or nano. Fractality, as a scale-independent morphology, provides significant opportunity for energy storage. From the viewpoint of scaling, the relation between large and small in fractal analysis is very important. An ideal fractal can be magnified endlessly but natural morphologies cannot, what in the new inlight of materials sciences and space.

From Flash Sintering to Water-assisted Flash Sintering and Beyond: Energy and Cost-Saving Materials Processing Technologies: Jian Luo1; 1University of California, San Diego
This talk will review a series of our studies of flash sintering using ZnO as a model system. A coupled thermal and electric runaway model has been developed to forecast the onset flash temperatures [Acta Mater. 94:87 (2015)]. Further studies suggested that the rapid heating profiles enable the ultrafast densification rates [Acta Mater. 125:465 (2017)]. A two-step flash sintering (TSFS) technology was invented to densify nanocrystalline ceramics with suppressed grain growth [Scripta Mater. 141: 6 (2017)]. In a new water-assisted flash sintering (WAFS) technology, we can start a flash at room temperature to subsequently densify a ZnO specimen to ~98% densities in 30 s [Scripta Mater. 142: 79 (2018)]. The relevant scientific questions and technological opportunities of flash sintering are discussed in a recent Viewpoint Article [Scripta Mater. 146: 260 (2018)]. Our most recent ongoing research on several related areas will be presented and discussed.
