Synthesis and Electrochemical Studies of Sodium β’’-Al2O3/10Sc1CeZr Composite as a Two Independent Phase Mixed Ion Conductor: Pouyah Elahi1; Taylor Sparks1; 1University of Utah
    Ion conductors can be classified into one species, single-phase and multi-phase mixed ion conductors. One species ion conductors have been significantly studied. The main difficulty in tuning a single-phase class of conductors is the inter-dependency of the ions' transport and influence of one on the other species. In single-phase, mixed ion conductor systems, the thermodynamic properties of the whole system, such as operating temperature, chemical potential, and atmosphere composition, will affect the total conductivity. Here we used a method to synthesize, characterize, and electrochemically study a two-phase composite sodium β’’-Al2O3/10Sc1CeZr, oxygen and sodium ion conductors to tackle the complicity of the optimization and modification of the designed electrochemical system for multi-ion conductors. Since two phases constitute a contiguous composite, the ion transport properties are independent of other species; while electrochemical neutrality is globally and thermodynamic equilibrium is locally achieved.

Design Paradigm for Manufacturing Functional Materials from Environmentally Benigh Precursors: Surojit Gupta1; 1University of North Dakota
    Environmental concerns and sustainability have become critical consideration for manufacturing. To meet this critical need, novel benigh precursors are needed for sustainable manufacturing. In this presentation, I will present and review some of the recent progress in research group. More particularly, I will focus on ceramics and porous materials. The correlation of processing parameters, microstructure, and properties will be systematically delineated in the presentation.

In-situ Surface Modification of Biocompatible 3D Printed Polylactic Acid (PLA) and PLA Composites Using Plasma Micro-discharge: Sankha Banerjee1; Saquib Ahmed2; Deidra Hodges3; Edbertho Leal-Quiros4; 1California State University, Fresno; 2State University of New York at Buffalo State; 3Florida International University ; 4University of California, Merced
    Cell growth, cell adhesion, and proliferation on biocompatible polymers and polymer-based composites are affected by the surface energy and the interfacial properties. One of the major factors that affect adhesion is contamination by different microorganisms. This contamination and simultaneous growth of microorganisms can affect the quality and quantity of healthy cells that grow on the surface. Polylactic Acid (PLA) is a biodegradable polyester material produced from renewable resources like biomass. Additionally, its biocompatibility has permitted its use in food packaging and the biomedical industry. Despite its benefits, PLA intrinsically lacks strength, durability, and adhesiveness. The current work focuses on mitigating these problems by incorporating surface modification techniques to modulate the surface roughness metrics of PLA. PLA and PLA-based composites were 3D printed and then treated with in-situ corona discharge, a method widely used in a variety of industries because of its safety, low cost, and overall effectiveness.

Long-term Stability Improvement of Perovskite Solar Cells through a Solvent-free Encapsulation Method: Manuel Salado1; David Payno1; Shahzada Ahmad1; 1BC Materials
    The long-term stability of perovskite solar cell has been one of the main concerns regarding the up-scaling of this technology. In this work, we develop a simple, fast and green method to encapsulate perovskite solar cells maintaining the optoelectronic properties over 300 days after water immersion. The use of a photo-curable monomer offers a fast encapsulation as well as avoid the need of any solvent that could degrade the perovskite layer. Electronic characterization of the devices (J-V curves, IPCE and Impedance Spectroscopy) did show barely changes in the sample's behaviour. In addition, encapsulated samples kept 80% of their initial PCE after ageing test with several environmental conditions. This encapsulation process will contribute to the development of both extraordinarily efficient and stable solar cells.
