Performance degradation under environmental conditions currently limits the practical utility of perovskite-based solar cells. The moisture stability of CH3NH3PbI3 perovskite films and solar cells was measured during exposure to three different level

The fluorescence intensity and transport kinetics of uranyl into mesoporous silica gel was measured in the presence of six naturally occurring cations. It was shown that the presence of the cations can reduce the fluorescence intensity of the uranyl

Gamma spectroscopy was used to quantify the accumulation of the uranyl ion (UO22+) into mesoporous silica gel in an aqueous solution under static and pressure-driven flow conditions. The amount of uranyl accumulated into silica gel under static condi

The fluorescence lifetime of uranyl adsorbed within nanoporous silica gel was measured as a function of pore size at two different pH values and both wet and dry. It was determined that for uranyl adsorbed within pores larger than 4 nm, the lifetime

Perovskite-based solar cells with high power conversion efficiency were produced by annealing the perovskite layer at low temperature in the presence of supercritical carbon dioxide (scCO2). Photovoltaic devices were produced with perovskite layers a

Uranyl transport into nanoporous silica gel is limited in a static aqueous solution by slow natural diffusion to the open bonding sites. In order to make this process faster, the diffusion dependence was eliminated using pressure driven fluid flow. U

Crystallization of CH3NH3PbI3 perovskite films was performed in supercritical carbon dioxide with and without organic cosolvents. Post deposition crystallization of the films was performed in a binary, single phase supercritical fluid at constant con

Trace quantities of a uranyl dissolved in water were measured using a simple optical method. A dilute solution of uranium nitrate dissolved in water was forced through nanoporous silica gel at fixed and controlled water flow rates. The uranyl ions de

The fluorescence of organic fluorophore molecules is enhanced when they are placed in contact with certain metals (Al, Ag, Cu, Au, etc.) whose surface plasmon waves couple into the radiative modes of the molecules and increase the radiative efficienc

We report the fabrication and characterization of thin films from the water soluble polymer sodium poly[2-(3-thienyl)-ethyloxy-4-butylsulfonate] (PTEBS) by electrospray deposition (ESD). Contiguous thin films were created by adjusting the parameters
