Phenyl SAMMS 2
The need to develop inexpensive and efficient filtration media is a high priority for researchers, and in turn offers a challenge for finding new, functional, designer materials that have high uptake capacities and selectivity for environmental contaminants. Phenyl SAMMS is one such high uptake, selective binding substrate. Self-Assembled Monol...

Enhanced Photovoltaic Efficiency by Heterojunction Assisted Impact Ionization
Charge multiplication by impact ionization (II) produces ~1% of the photogenerated charge in silicon photovoltaic (PV) devices under solar illumination and ~30% for photons above the silicon direct band gap. Despite these observations, few efforts have been reported to find materials and structures that optimize the rate of II and thereby conve...

Heterometallic Group 13 Keggin-like Nanoclusters
The Johnson research group has developed a high-yielding synthetic strategy for preparing discrete polynuclear inorganic clusters containing thirteen Group 13 metals (Al, Ga, In) in a Keggin-like structure. Seven of the metal ions comprise the interior core, arranged in a flat hexagonal disc and bridged by hydroxo ligands. The remaining six m...

Polymer Light Emitting Devices Based On Interfaces Enabled By Internally Compensated Doped Conjugated Polymers
There is a need for low cost, stable and efficient light-emitting devices for solid-state lighting. Polymer light-emitting electrochemical cells (PLECs) are being actively explored for their potential in this area. The stability and efficiency of current PLECs needs to be improved if they are going to be practical. In order to improve stabi...
