Novel tunable optical filter employing a fiber loop mirror for synthesis applications in WDM
(11/12/2001)
A novel optical filter employing a fiber loop mirror within an amplified ring resonator is presented. The fiber loop mirror allows tuning by changing the coupling factor of a coupler. The device can be used as a building ...

Modeling Competitive Cation Exchange of Aromatic Amines in Water-Saturated Soils
(06/01/2001)
Competitive association to several components of soil through ion exchange processes influences the fate of organic cations in the environment. To examine these processes, the distributions of aniline and 1-aminonaphthalene ...
Role of pH in partitioning and cation exchange of aromatic amines on water-saturated soils
(08/04/2001)
Predicting the reversible interactions between aromatic amines and soil is essential for assessing the mobility, bioavailability and exposure from contaminated sites. Reversible sorption mechanisms of aniline and α-naphthylamine ...
