Abstract Marine geoengineering (the specific subject of this talk) is one of the scientific techniques that could ultimately help combat global warming. As such, it is the subject of this symposium. However, it also presents a serious and irreversible …

Abstract The control of irrigation by a bureaucratic apparatus linked to religious and/or state power is at the heart of social theories that have marked the history of ideas over the last one hundred and fifty years. Although largely discredited, they …

Abstract Sharp structures can occur as minimizers of very regular problems. This means symmetry can lead us badly astray and the resultant symmetry breaking may lead to highly counter-intuitive structures. I will illustrate in a discrete example and then …

Abstract When it comes to exploring Greek poetic material to study the role of the gods in sacrificial contexts, tragedy is a prime example. Indeed, the association between tragedy and sacrifice is one of the most historiographically charged ever, for at …

Abstract Surface-initiated polymerization is a unique way to produce thin, functional polymer films. As polymer chains are grown from surfaces that are modified with initiators or chain transfer agents to mediate chain growth, this process ensures a …

Abstract Many drugs or drug candidates have physico-chemical characteristics that are unfavorable to the passage of the biological barriers that separate the site of administration from the site of pharmacological action. These mechanical, …

Abstract Amyloid fibrils interact with metal ions via metal-ligand supramolecular interactions whose energy is of the order of tens to hundreds of KBT. The occurrence of the 20 essential amino acids in food-based amyloid fibrils derived from inexpensive …

Abstract Our lab has pursued development of methods to allow selective incorporation of diverse functionality into synthetic polypeptide materials. Specifically, we have developed synthetic methods that allow a robust variety of modifications to …
