Research seminar: Super-resolution microscopy circumvents the diffraction limit of light so that emitters separated by ~5 nm can be resolved. While electron microscopy achieves better resolution, light microscopy records the fluorescence dynamics of the system, which are often indicative of underlying processes such as charge and energy transfer. However, most super-resolution images are acquired on […]

About the Seminar: Porosity in network solids, including zeolites, activated carbons, and metal-organic frameworks, has been widely interrogated for decades. In molecular metal-organic systems, however, it is a relatively novel phenomenon. This is somewhat surprising given the fact that porous organic cages can display surface areas that rival those of metal-organic frameworks. This talk will […]

About the Seminar: Nature produces soft materials possessing exceptional mechanical properties. These properties are to a large extent related to the well-defined structures and locally varying compositions of these natural materials. Key to the excellent control nature possesses over the structure and local composition of its materials is their fabrication: Many of these materials are […]

Nature has inspired inorganic chemists to look beyond the immediate coordination sphere of complexes to tune and optimize reactivity. Two important themes have been the use of pendant proton donors/acceptors as well as incorporating redox-active moieties into ligand scaffolds. However, nature does not limit itself to an “either/or” strategy, and uses both of these features […]

Coinage metal-thiolate assemblies exemplify hierarchical structure and structure-property relationships. They comprise structurally weak hydrogels of stacked sheets. Inclusion of an anti-solvent in synthesis of these materials fundamentally changes their structure, resulting instead in colloidal amorphous metal complexes. The colloids undergo a hydration-dependent and reversible sol-gel transition. Because the colloids are flexible, they morph in the […]

Pancreatic cancer is the fourth leading cause of cancer deaths in men and women. In general, pancreatic tumors are hypovascular and nutrient-deprived when compared to normal tissue or other cancer lines. As such, new cancer therapeutics are being investigated that utilize the “anti-austerity” strategy. An anti-austerity agents removes the ability of cancer cells to survive […]
