Synthesis Protocol

An automated synthesis protocol is developed for the synthesis of block copolymers in a multi-step approach in a fully automated manner. For this purpose, an automated dialysis setup is combined with robot-based synthesis protocols. Consequently, several block copolymerizations are executed completely automated and compared to the respective manual synthesis. As a result, this study opens up the field of autonomous multi-step reactions without any human interactions.

Human Rationality

The paper describes the contributions of T. Schelling and R. J. Aumann, the Nobel Prize laureates of 2005 in economics, to modern economics and social sciences. Their key contributions were in the field of the game theory - a major tool to study human interactions and rational behavior in a wide variety of contexts, from applied industrial organization to labor economics, public policy, international relations and political science. Works by Aumann and Schelling were pathbreaking in this respect, and have paved the way to many modern developments that enhance our understanding of human rationality.

AbstractTriblock copolymers have traditionally been synthesized with conventional organic components. However, triblock copolymers could be synthesized by the incorporation of two incompatible protein-based polymers. The polypeptides would differ in their hydrophobicity and confer unique physiochemical properties to the resultant materials. One protein-based polymer, based on a sequence of native elastin, that has been utilized in the synthesis of biomaterials is poly (Valine-Proline-Glycine-ValineGlycine) or poly(VPGVG) [1]. This polypeptide has been shown to have an inverse temperature transition that can be adjusted by non-conservative amino acid substitutions in the fourth position [2]. By combining polypeptide blocks with different inverse temperature transition values due to hydrophobicity differences, we expect to produce amphiphilic polypeptides capable of self-assembly into hydrogels. Our research examines the design, synthesis and characterization of elastin-mimetic block copolymers as functional biomaterials. The methods that are used for the characterization include variable temperature 1D and 2D High-Resolution-NMR, cryo-High Resolutions Scanning Electron Microscopy and Differential Scanning Calorimetry.

Existential Issues

Although primarily known as a feminist scholar and author of such works as She Came to Stay and The Second Sex, Simone de Beauvoir contributed heavily to French existential thought. The two writings upon which this paper focuses, The Ethics of Ambiguity and The Woman Destroyed, deal with the existential issues involved in human interactions and personal relationships. The Ethics of Ambiguity, famous as an exploration of the ethical code created by existential theory, begins with a criticism of Marxism and the ways in which it deviates from existentialism. Similarly, the first of the three short stories that make up de Beauvoir’s fictional work The Woman Destroyed follows the French intelligentsia and their similarities and digressions from Marxist and existential thought. In this paper, I seek to analyze Simone de Beauvoir’s criticism of Marxist theory in The Ethics of Ambiguity and its transformation into the critique of intellectualism found twenty years later in The Woman Destroyed. I will investigate Marxism’s alleged attempts to constrain the group it wishes to lead and the motivation behind these actions. Finally, I conclude with a discussion of the efficacy of fiction as a medium for de Beauvoir’s philosophy.

<p>Block copolymers are used to construct covalent adaptable networks that employ associative exchange chemistry (vitrimers). The resulting vitrimers display markedly different nanostructural, thermal and rheological properties relative to those of their statistical copolymer-derived counterparts. This study demonstrates that prepolymer sequence is a versatile strategy to modify the properties of vitrimers.</p>
