Increasing methylation of the headgroup in DPPE results in an increase of minimum area per molecule in highly compressed monolayers at the air-water interface. The shape of solid domains, as observed by epifluorescence microscopy, also exhibits marked changes upon increasing headgroup methylation. B
## Abstract This article questions the use of focus groups for assessing consumer attitudes. A repeatedβmeasures research design was used to determine whether the interaction and discussion among focusβgroup participants changed their attitudes. Experimental results indicate that focusβgroup partic
Permeability coefficients of Hz, Oz, and Nz were measured under 10 atm at the temperature from ambient temperature up to 15OoC in a series of structurally different aromatic homoand copolyimides, which were prepared from 4,4'-oxydianiline (ODA) or 4,4'-methylene dianiline (MDA) with various aromatic
