The formation of complex inorganic superstructures in nature relies on the interaction between organic and inorganic species to direct the inorganic form away from its “usual” morphology. During synthesis the superstructures are soft and dynamic which makes a study of the nature of the ephemeral interface difficult. However, the inorganic skeletons formed are stable and consequently amenable to...

Disk-shaped π-surfaces that stack to form columnar structures1 are prototypes of molecular-scale wires that have an insulating hydrocarbon sheath surrounding a conductive aromatic core.2 Typically, the strengths of the associations between the molecules, formed through contacts between aromatic surfaces, are weak. Previous schemes to modulate these strengths are based on metalligand interaction...

This project examines a sequence of Tertiary volcanic rocks from the Langidalsfjall mountain range in the Skagi Peninsula of north-central Iceland, formed at about 7-8 Ma. This sequence is composed of basaltic flows, andesitic flows, and rhyolitic rocks (a flow and a dike). The main unit of interest is a 30-40 m thick plagioclase-phyric andesite flow. This flow contains calciumrich (up to An88)...

Cereal Chern. 84(4):415-422 Starch granules undergo structural and morphological changes during food processing unit operations as they interact with other food ingredients. This study was conducted to isolate and characterize starch granules from com masa. A proteolytic enzyme, thermolysin, was effective in separating and isolating starch granules from endosperm proteins present in masa. The e...
