An ambient air sampling study was conducted around a municipal waste combustor; a primary goal was to develop procedures and methods to evaluate the emissions of organic mutagens resulting from incomplete combustion of municipal waste. The products of incomplete combustion from incineration include complex mixtures of organics, particularly polycyclic(More)
Quantitative health risk assessments have been performed for a number of proposed municipal waste combustor (MWC) facilities over the past several years. This article presents the results of a comparative analysis of a total of 21 risk assessments, focusing on seven of the most comprehensive methodologies. The analysis concentrates on stack emissions of(More)
The synthesis and magneto-optical properties of HgTe nanocrystals capped with HgxCd1-xTe(S) alloyed shells have been investigated. The magneto-optical measurements included the use of optically detected magnetic resonance (ODMR) and circular polarized photoluminescence (CP-PL) spectroscopy. The PL spectra suggest the existence of luminescence events from(More)
The review describes the studies of the magneto-optical properties of II-VI and III-V semiconductor nanocrystals (NCs) capped with organic or inorganic epitaxial shells. The investigations focused on the chemical identification of localization sites (core, shell, or interface) of photogenerated carriers in spherical NCs and elucidated the influence of the(More)
Several semianalytical approaches are now available for describing diffraction of a plane wave by the 2D (two dimensional) traction free isotropic elastic wedge. In this paper we follow Budaev and Bogy who reformulated the original diffraction problem as a singular integral one. This comprises two algebraic and two singular integral equations. Each integral(More)
An investigation of the optical and magnetic properties of a unique hydrogen-linked conjugate nanostructure, comprised of superparamagnetic gamma-Fe(2)O(3) nanoparticles (NPs) and near-infrared PbSe nanocrystal quantum dot (NQD) chromophores, is reported. The results show retention of the NQDs' emission quantum efficiency and radiative lifetime, and only a(More)
The magneto-optical properties of chromophore/semiconductor nanocrystalline superstructures were examined using optically detected magnetic resonance (ODMR) and time-resolved photo-luminescence (PL) spectroscopy. The samples consisted of CdS or PbS nanocrystals separated by conjugated organic chains, forming three-dimensional superstructures. The ODMR(More)
