Potential Additive-Manufacturing of Ablative Thermal Protection Systems

Creator:: Hazell, Kenya K.
Abstract:: Electrodeposition is a versatile polymer deposition technique to create nano-microscale materials using an electrical field generated from a charged droplet of solution and a grounded collector. Electrospinning or electrospraying can occur during electrodeposition, leading to the creation of nanofibers or bead-like materials depending on the process parameters. Photopolymerization of the...

Development of new high-temperature piezoelectric perovskite ceramics

Creator:: Ansell, Troy Youngmin
Abstract:: Lead zirconate titanate (PZT) is the dominant ferroelectric material in the market due to its excellent piezoelectric properties, relatively high Curie transition temperature (T[subscript C]), low cost, etc. However, because of emerging applications with requirements for high temperature (T[subscript C] > 400 °C) ferroelectrics, researchers are increasingly looking at alternative...

Development of bi-based lead-free piezoelectric materials : thin film piezoelectric materials via PVD and CSD routes

Creator:: Jeon, Yu Hong
Abstract:: Piezoelectric materials have been widely used in electromechanical actuators, sensors, and ultrasonic transducers. Among these materials, lead zirconate titanate Pb(Zr[subscript 1‐x]Ti[subscript x])O₃ (PZT) has been primarily investigated due to its excellent piezoelectric properties. However, environmental concerns due to the toxicity of PbO have led to investigations into alternative materials systems....
