Targeted ligand design using a combined computational and experimental approach to unlock new metal separations
No full textAs societal demand for metals grows, sustainable routes to their efficient recovery from primary ores and secondary waste streams have become increasingly important. In this regard, understanding the chemical detail of metal separations is implicit to designing more efficient and environmentally benign processes. Herein, we report a combined computational and experimental approach to targeted ligand design by modification of a simple diamide (L), previously reported as a selective precipitant for Au. This afforded three new reagents through the addition of electron-donating (LOMe) and withdrawing (LCl) groups, and the inversion of the amide linkage (Linv). Computational studies confirmed the expected trends in protonation of the amide and subsequent metal uptake experiments showed all ligands act as selective precipitants for Au at low acid concentrations in the presence of an excess of ligand. Significantly however, the use of stoichiometric amounts of LOMe and LCl resulted in a switch in selectivity from square-planar (AuCl4-) to tetrahedral metalates (GaCl4- and FeCl4-), with precipitation suppressed for Linv. Computational modelling rationalised this reversal in metalate selectivity with LOMe and LCl on thermodynamic grounds, while Hirshfeld surfaces, NCI plots and QTAIM analyses highlighted halogen bonding as the most important structure directing interaction. Importantly, preliminary studies with LOMe suggested a viable pathway to the separation of Ga and Fe from industrially generated waste streams, which could be exploited in the recycling of zinc residues and end-of-life GaN light-emitting diodes

Why I Can’t Love the Homemade Semantic Web

Gold precipitation by diamides - ICP-OES and NMR data
No full textThe efficient separation of gold and other metals from their ores and composite secondary sources such as electronic waste is necessary to realising circularity in metal supply chains. Processes based on precipitation are becoming increasingly popular and their development is reliant on designing and understanding chemical recognition to achieve selectivity. Here we show that the simple tertiary diamide PhC(O)NMe(CH2CH2)NMeC(O)Ph (L) precipitates gold selectively and directly from aqueous acidic solutions as the ion pair [HL][AuCl4], including from aqua regia solutions of electronic waste. The X-ray crystal structure of the precipitate displays an infinite chain of diamide cations, formed through an intermolecular proton chelate, interleaved with tetrachloridoaurate. Gold is released quantitatively from the isolated precipitate as HAuCl4 on contact with water, enabling ligand recycling. The diamide is highly selective, with its addition to a mixture of 29 metals in 2 M HCl resulting in 70% gold uptake and minimal removal of all other metals. Increasing the HCl concentration to 6 M allows complete collection of gold, iron, tin, and platinum, demonstrating that L is an adaptable selective metal precipitant controlled by just one variable. Thus, this discovery could be exploited in metal refining and recycling processes due to its tuneable selectivity under different metal leaching conditions, the avoidance of organic solvents inherent to biphasic extraction, and the straightforward recycling of the precipitant

Jason vs GIJOE
No full textThesis (Master's)--University of Washington, 2019Jason vs GI JOE is partly an exercise in autobiography, an experiment in relational aesthetics, and an interdisciplinary artist project at the intersection of comic books, creative writing and performance art. This comic book, Jason vs. GIJOE, is a postmodern double erasure, based on the comic book GIJOE: Cobra II (Issue 1). The original pictures from the comic book have been removed, and replaced by a series of short narratives, describing autobiographical events from the life of the author: me, Jason. Speech bubbles from the original have been left to comment back over top of the stories, obscuring meaning but creating moments of unplanned dialogue. The comic is a readymade, twice erased: once to replace the drawings of the initial comic, and again when using the original dialogue bubbles to speak back to the narrative

Euripides’ Medea and Jason: A Study in the Social Power of Love
No full textEuripides’ Medea resonates with modern issues in intimate relationships. However, little has been written on this, especially from the social-psychological perspective. This paper explores the breakdown of the Jason-Medea marriage in terms of the social-psychological theory of love as an exchange in a power game in which a certain degree of imbalance in the exchange could account for such a breakdown. I analyse the Medea text in terms of Olson and Cromwell’s (1975) tripartite theoretical framework, namely: (a) the bases on which social power is built; (b) the processes by which social power is wielded; and (c) the outcomes produced by the use of social power. I find that Medea carried a greater burden of love towards Jason than Jason did towards her, fuelled and sustained by her enduring and greater need for security and happiness. And in intimate relationships, the principle of least interest (Waller and Hill 1951) works: the beloved tends to dominate the lover. Jason, however, overreached himself when he violated the minimum conditions of his own desirability – fidelity to and respect for Medea. I conclude that Medea’s violent reaction to Jason’s conduct indicates the fragility of love as a basis of social power in intimate relationships
