Developments in Quantitative Organic Ultramicro Elementary Analysis
Numerous principles for the mineralization of samples and for the measurement of the elements have been tried since the days of Liebig, Dumas, Dennstedt and Pregl. Attempts to develop accurate and reliable ultramicro methods have been successful only in recent years. Almost absolutely quantitative recovery of the analyte from the mineralization process, freedom from risk of contamination, and v...
متن کاملQuantitative Analysis of Electron Beam Damage in Organic Thin Films
In transmission electron microscopy (TEM) the interaction of an electron beam with polymers such as P3HT:PCBM photovoltaic nanocomposites results in electron beam damage, which is the most important factor limiting acquisition of structural or chemical data at high spatial resolution. Beam effects can vary depending on parameters such as electron dose rate, temperature during imaging, and the p...

متن کاملQuantitative analysis of the functionalization of gallium phosphide with organic azides.
Gallium phosphide (GaP) surfaces were functionalized with two different molecules that contain an azide moiety at their terminus. Compound 4-azidophenacyl bromide (4AB) is an aryl azide with a bromine group at its opposite terminus that provides easy identification of the molecule's presence on the surface with x-ray photoelectron spectroscopy (XPS). O-(2-aminoethyl)-O'-(2-azidoethyl)pentaethyl...
