Naphthoquinone methide dyes show a large Pockels coefficient at 1.3 µm when poled in a polymer matrix: the second-order nonlinear hyperpolarizability (µβ) values obtained from Pockels coefficients that appear after poling in a constant electric field are (5700–7400)× 10–48 esu, being much higher than that of commonly used Disperse Red 1 (DR1).

Powder X-ray diffraction, 29Si and 129Xe NMR spectroscopy of MCM-41 show that the long-range structural order and textural uniformity of the mesoporous molecular sieve are markedly improved due to a shift in the reaction equilibrium when acetic acid is repeatedly added during the conversion of sodium silicate and NMe3(C16H33)Cl to a MCM-41 phase.

Silica-supported tantalum hydride activates at low temperature the C–H and the C–D bonds of cyclooctane and CD4, respectively, to form the corresponding cyclooctyl and perdeuteriomethyl-tantalum surface complexes; these complexes are transformed under molecular oxygen into the corresponding tantalum-alkoxy derivatives which with acetic acid give rise to the corresponding alkylacetates.
