Functional electrospun fibers for responsive coatings and sacrificial templates
… we study two polymer systems for use as sacrificial templates for developing microvasculature. Poly(lactic acid) and cyclic poly(phthalaldehyde) fibers are electrospun, embedded into epoxy, and thermally or chemically decomposed to remove the fiber and create channels. Characterization of …

Synthesis and properties of transition-metal arsenide nanostructures: from superparamagnetism to superconductivity
… through solid-solid conversion route aided by sacrificial templates"--Abstract, page iv.</p>

Biofabrication technologies enabling vascularization of organ- scale engineered tissues for clinical translation
… after implantation remains a major challenge. Sacrificial templating has emerged as a promising strategy that could overcome this challenge by confining fabrication stressors to a temporary scaffold that is later removed, leaving behind perfusable channels for convective transport of nutrients, …

Three-dimensional metallic architectures for photonic and energy storage applications
… for photonic and energy storage applications. Sacrificial templates are commonly used for the fabrication of materials possessing 3D structure. Self-assembly is particularly attractive for applications demanding large-area templates at low cost. This work focused on the incorporation of …

Colorimetric sensor array for identification of fungi & ultrasonic spray synthesis for supercapacitor materials
… steps) or expensive (such as nano-structured sacrificial templates), and can easily introduce impurities that negatively affect the electrochemical properties of the PEDOT products. In this project, we used ultrasonic spray polymerization (USPo) method for facile and continuous PEDOT …

Sacrificial polymers for rapid manufacturing of bioinspired vascular materials
… pullout, dissolution, melting, or evaporation of sacrificial templates (metal wires, fugitive inks, photoresists) embedded in a host matrix to leave hollow conduits ranging from microns to meters in length. Most sacrificial materials cannot be easily templated into complex interconnected …

Bioinspired microvascular self-healing in polymers and composites
… materials has been limited due to the delicate, sacrificial templates used to construct the inverse vasculatures. This dissertation outlines further development of in situ, microvascular self-healing in heterogeneous polymeric materials, particularly fiber-reinforced polymer composites, to …

Transition Metal Heterogeneous Catalysis Towards Applications in Sustainable Energy: Leveraging Rational Design Principles for Activity, Stability, and Stereoselectivity
… Finally, MHOFs present unique opportunities as sacrificial templates for thermocatalysis, with adjustable metal centers, structural robustness, and heteroatom incorporation through linker selection. In this thesis I present a model for using MHOFs and analogous MOFs to generate catalysts with …

Micro- and nanostructured materials via ultrasonic spray pyrolysis
… but prior synthetic methodologies using sacrificial templates increase complexity, cost, and waste. Using a one-step and template-free USP approach, gold NPswere encapsulated in situ in a highly porous carbon support, thus preventing sintering while still permitting accessibility to the …

Thermal regulation of vascularized fiber-reinforced polymer matrix composites
… uses the established Vaporization of Sacrificial Components (VaSC) technique for manufacture of the vascular network. In this method, sacrificial templates composed of a thermoplastic polymer and catalyst are embedded in the fiber preform prior to PMC manufacture, and then removed by …
