We study smectic liquid crystals in random environments, e.g., aerogel. A low-temperature analysis reveals that even arbitrarily weak quenched disorder (i.e., arbitrarily low aerogel density) destroys translational (smectic) order, in agreement with recent experimental results. A harmonic approximation to the elastic…

Surface-enhanced Raman spectroscopic (SERS) experiments on thin films of free base phthalocyanine (H2Pc) with embedded silver clusters are reported. The thin films were produced by thermal evaporation of H2Pc together with different amounts of silver (8, 15 and 26 vol.%). From transmission electron microscopy it turne…

A relation between nitrogen desorption/mercury intrusion porosimetry‐measured pore size and green density of a powder compact is examined with respect to data from the literature, as well as data from the current study on three ceramic oxides. In almost all cases, the relationship is well obeyed. Deviations from the r…
