(University of Oregon, 2022-10-26)Hydrogen selenide (H2Se) is the central species in the selenium metabolic cycle, sitting at the crossroads of protein-synthetic and excretory pathways. Despite its importance in biology and potential for therapeutic ...
-
(University of Oregon, 2022-10-26)Due to their generally poor conductivity, metal–organic frameworks (MOFs) have been limited in electrical applications. In this dissertation we explore structural deformation as a route to augmenting the electronic properties ...
-
(University of Oregon, 2022-10-26)Atomic, molecular, and porous material void space shape and size play a critical role in chemistry. The most familiar method was formalized by Bondi: the van der Waal radii and volume of atoms and molecules. However, the ...
-
(University of Oregon, 2022-10-26)Supramolecular chemistry is an ever-growing area in science that studies noncovalent interactions between small molecules and/or ionic species through molecular recognition or self-assembly. Host-guest chemistry is a branch ...
