Investigation of Electroplated 3D Printed Antennas: Muneer Barnawi1; Trenton Cersoli1; Kerry Johnson1; Edward Burden1; Eric MacDonald1; Pedro Cortes1; 1Youngstown State University
Shape memory polymers (SMPs) are materials capable of changing their structural conformation when subjected to a thermal stimulus. Nowadays, the incorporation of SMPs within the 3D printing technology has allows the production of customized and intricate smart structures. One attractive area in the field of morphable structures is the production of adaptive aerial devices. The present work has investigated the production of 3D printed co-polymer substrates using a vat polymerization technology to be used as the platform for copper electrodeposition. Here, different co-polymers mixtures have been evaluated to produce an actuating structure. The investigated copper coating has resulted in a robust morphing antenna capable of providing unique multi-radio frequencies. The radiofrequency performance of the manufactured smart antennas seems to fit within the preliminary modeling performed by an electromagnetic software.

NSMM Modeling of Materials, Including Dipole Engineered Novel Relaxors: Steven Tidrow1; 1Alfred University
Dipole engineering at the nanoscale results in modification of materials like BaTiO3 from ferroelectric, to diffuse phase, to relaxor-like properties using the lowest substitution levels of any known ferroelectric material system. Such low level substitutions are important toward material sustainability and development of impactful material properties without use of Pb. Dipole engineering at the nanoscale affords both scientific and engineering tools for investigating, developing and tailor design engineering material properties. The new simple material model (NSMM) is reviewed and used to improve our scientific understanding of novel dipole engineered relaxor-like materials. NSMM is shown to be a reliable tool for tailor engineering of properties of dipole engineered materials, including temperature dependent lattice parameter, Tc, Tm, diffuseness, etc.

Topological Insulator Design for Quantum Computers Targeting BSTS Single Crystal Fabrication: Husain Alnaser; 1
Quantum computers are made possible to make and use day after day due to the emerging of topological insulator materials. One of the hottest topics in topological insulator materials’’ fabrication is BSTS (Bi-Se2-Te-Sb) single crystal system. Many researchers had tackled the challenge to create BSTS single crystal but they are lacking a solid scientific ground to further analyses the system and give explanation for its mechanics. This study will present a fundamental scientific approach that gives accurate predictions and assumptions by using theoretical thermal modeling through using CALPHAD approach (ThermoCalc) followed by a series of characterization techniques. The findings from both the theoretical and the experimental results converged to give an explanation for the BSTS single crystal system mechanics that can be useful for researchers to apply the method not only on BSTS but can be applied on their targeted system as well.
