The concentration and chemical composition of ambient fine particulate material (PM2.5) is reported for two sampling sites in the Pittsburgh, Pennsylvania metropolitan area: the Department of Energy, National Energy Technology Laboratory (NETL) PM study si ...
Monolayers of gramicidin A, pure and in mixts. with dimyristoylphosphatidylcholine (DMPC), were studied in situ at the air/H2O and air/D2O interfaces by polarization-modulated IR reflection absorption spectroscopy (PM-IRRAS). Simulations of the entire set ...
Poly(vinylbenzylammonium chloride) (PVBAC) polyelectrolytes possessing defined chain lengths, narrow chain length distributions, uniform charge d., but substituents of different hydrophilicity and size at the quaternary ammonium group were used as model co ...
New types of oxygen-sensitive membranes based on immobilized (meso-α,α,α,α-tetrakis(o-pivalamidophenyl)porphinato)cobalt(II) (CoP) were prepared, and their optical response behavior was studied. The complex CoP was immobilized on poly(octylmethacrylate-co- ...
Specific volumes of forsterite and San Carlos olivine have been measured by in-situ X-ray diffraction at simultaneously high pressure and high temperature up to 7 GPa and 1300 K in a cubic-anvil press coupled to synchrotron radiation. No difference could b ...
CsI photocathodes were studied in order to evaluate their potential use as large photoconverters in RICH detectors for the PID system at ALICE (LHC in heavy ion collider mode). It has been demonstrated that a quantum efficiency comparable to the reference ...
This thesis describes the development and selected applications of a global vegetation model, BIOME4. The model is applied to problems in high-latitude vegetation distribution and climate, trace gas production, and isotope biogeochemistry. It demonstrates ...
For the analysis of flows in compliant vessels, we propose an approach to couple the original 3D equations with a convenient 1D model. This multi-scale strategy allows for a dramatic reduction of the computational complexity and is suitable for "absorbing" ...
We develop a microionizer as the ion source in a miniaturized spectrometerlike gas analyzer, operating at atmospheric pressure. Several options for the ionizing principle were considered. The application of dc glow discharge in a microsystem was studied in ...
Recent developments in Raman spectroscopy at high pressure, high temperature and combined high pressure and variable temperature are presented. The instrumental and technical aspects of Raman spectroscopy, and coupling of diamond anvil cells and miniature ...
