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

This paper describes research to characterize the benefits of a multiwavelength oceanographic LiDAR for various water types. Field measurements were conducted to establish endmembers representative of both typical and extremely challenging natural co

The photochemical reflectance index (PRI) is correlated to photosynthetic efficiency and has been successfully applied at multiple scales for remote estimation of physiological functioning. However, interpretation of the PRI signal can be confounded

A passive signal enhancement device for the standoff detection of uranium in soil was developed and tested. The device consists of a spherical ball lens half-coated with a polymer–silica gel composite. The nanoporous silica gel, when placed in cont

A series of models using cellular automata (CA) are created to examine the influences on the phenomenon of solute aggregation. The models used the variations in hydropathic states of the solutes to produce changes in the clustering patterns. It was f

A cellular automata (CA) model of liquid water has been used to study self-diffusion and the diffusion of a solute. The influences of temperature and solute hydropathic state are modeled as variables in this process. The self-diffusion model correlat

Nanoporous silica gel was employed to extract uranyl from contaminated soil and to enhance the fluorescence intensity and lifetime. The fluorescence lifetime and intensity of uranyl ions absorbed within nanoporous silica gel was measured from pH 1–

Fluorescence spectra of 10-, 25- and 50-nm diameter CdS nanowires (relative dielectric constant = 5.4) self assembled in a porous alumina matrix (relative dielectric constant = 8-10) reveal peaks associated with free electron-hole recombination. The
