Towards Sacrificial Anode-Free Alkyne Electrocarboxylation
… alkyne electrocarboxylation routes rely on sacrificial metal anodes which inhibit their scalability and implementation in continuous flow systems. The aim of this research is to establish a scalable, sacrificial anode-free electrocarboxylation process. This work explores the sacrificial …

The artist as sacrificial in Schopenhauer's philosophy
… explorations to show that the artist is indeed a sacrificial figure in Schopenhauer’s work. Regardless of the fact that Schopenhauer does not confirm the artist-as-sacrificial paradigm explicitly, the claim can be made that he does — and indeed, must — tacitly accept it.

Sacrificial form: the libretti in English 1940-2000
This thesis focuses on the genre of libretto, the sung words for music theatre. The “little book” which accompanies every operatic performance is not just an extended program note to the spectacle, but in fact a substantial literary form in its own right. However, despite the immense influence of …

Dendritic Materials as a Dry Release Sacrificial Layer
… using the developed process to demonstrate a dry sacrificial etching technique. An array of cantilever beams 100 mum in width by 1000 mum in length was successfully released in 10 min. In addition, an array of microchannels was fabricated to better understand the limitations of HB560 …

Sacrificial Acts: Martyrdom and Nationhood in Seventeenth-Century Drama
Sacrificial Acts: Martyrdom and Nationhood in Seventeenth-Century Drama posits that the importance of sixteenth-century martyrologies in defining England's national identity extends to the seventeenth century through popular representations of martyrdom on the page and stage. I argue that drama …

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 …

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 …

The synthesis of nanoporous hydrogels using sacrificial block copolymers
… finally removing one of the polymer blocks. The sacrificial block needs to be degraded easily and controllably and the blocks must self-assemble. Desired properties for the non-degradable polymer block are that it be hydrophilic and that it can be crosslinked to form a hydrogel. Advantages of the …

Air-gap sacrificial materials by initiated chemical vapor deposition
… was selected as the potential air-gap sacrificial material among possible combination of twenty monomers and four crosslinkers. P(npMA-co-EGDA) was deposited onto substrates using initiated chemical vapor deposition (iCVD) technique. Spectroscopic data showed the effective incorporation …

Investigation of New, Low-Voltage, Aluminum, Sacrificial Anode Chemistries
… on the performance of low voltage, aluminum, sacrificial anodes. We have developed an overview of elemental trends and a comparison with literature, in support of a larger program on predicting anode behavior. The broader impact of this work was to enhance the ability to control corrosion and …

Fabrication of nanofluidic devices using electrochemical etching of sacrificial copper
… external electrical potential is applied to the sacrificial layer to accelerate the process. The electrochemical etching allows channels several hundred microns long to be created in approximately 20 minutes, compared to conventional chemical etching which will take several days. Etching rates …

Chemical vapor deposition of organosilicon and sacrificial polymer thin films
Chemical vapor deposition (CVD) produced films for a wide array of applications from a variety of organosilicon and organic precursors. The structure and properties of thin films were controlled by varying processing conditions such as the method and power of precursor activation, pressure, flow …

Sacrificial worship in Ancient Israel and its fulfillment in Jesus Christ
… little is generally known is the nature of the sacrificial system of the ancient Israelites. It is from this sacrificial system that the worship service of Christianity found the seeds of its early development.</p> <p>It is the purpose of this thesis to trace a view of the origin, purposes, and …

Synthetic vascular materials via a vaporization of sacrificial component (VaSC) approach
… these limitations. Namely, the vaporization of sacrificial component (VaSC). The chosen sacrificial material, poly(lactic acid) (PLA), can be easily incorporated into composites and undergoes a solid-to-gas transition at ca. 280 oC, which allows for the extraction of the gaseous product from the …

Voltaire: From Sacrificial to Judicial System in the Play The Orphan of China
… because they have overlooked the significance of sacrificial and judicial systems (in Europe and, more importantly, in China) in the play. In the first chapter, I will demonstrate Voltaire's theory of civilization by contrasting The Orphan of China with Rousseau's essays: Discourse on Arts and …

Sacrificial high-temperature phosphorus diffusion gettering for lifetime improvement of multicrystalline silicon wafers
… of the finished device. Here, we explore a "sacrificial" gettering step, in which gettering and emitter-formation steps are decoupled and optimized independently. The optimization of the sacrificial gettering step is guided by the Impurity-to-Efficiency simulation tool [2] and explores higher …

Fabricating Multifunctional Composites via Transfer of Printed Electronics Using Additively Manufactured Sacrificial Tooling
… conductive inks from additively manufactured sacrificial tooling to the composite surface. The process is demonstrated by creating multifunctional composites via embossing printed electronics onto structural composites without negatively affecting the mechanical performance of the structure. …
