(1988)Fluorescence techniques are used to study the effect of size on the properties of dioctadecyldimethylammonium chloride vesicles. The solubilization site and the deactivation rates of excited pyrene by bromide counterions ...
-
(1974)The absorbances in the uv region of sodium p-toluene sulfonate, sodium toluate, sodium benzene sulfonate and sodium phenyl phosphate have been measured in the presence of increasing amounts of cetyl trimethyl ammonium ...
-
(1988)A study of the adsorption and thermodynamic functions of sulfur dioxide on Aerosil has been made, leading to some conclusions about the mobility of the SO2 molecule. The differential and integral enthalpies and entropies ...
-
(2000)Electronic substituent effects may be rationalized in terms of Hammett- like linear relationships between global energy-dependent quantities and local electronic descriptors of reactivity. These linear relationships are ...
-
(1969)The reactions between hydroxide or fluoride ion and p-nitrophenyl diphenyl phosphate, catalyzed by micelles of cetyltrimethylammonium bromide, are inhibited by phenyl, diphenyl, and p-t-butylphenyl phosphate. With decreasing ...
-
(1993)Four sodium polysoaps from poly[malcic anbydride-co-styrene] were synthesized and the surface properties of their aqueous solutions at the air-water interface were determined. The surface tension lowering was directly ...
-
(1988)The kinetics of the quenching of excited pyrene by several molecules in a variety of hydrocarbon solvents and in a diol are reported. The rate constants for reaction of the excited pyrene are, for the most part, ...
-
(2012)Photoisomerization of a protein bound chromophore is the basis of the light sensing and signaling responses of many photoreceptors. Z-to-E photoisomerization of the Pr Cph1Δ2 phytochrome has been investigated by polarization ...
-
(American Chemical Society, 2001)Continuum solvent effect on the electrophilicity index recently proposed by Parr and co-workers (Parr, R. G.; von Szentpaly, L.; Liu, S. J. Am. Chem. Soc. 1999, 121, 1922) is discussed in detail. Solvent effect is introduced ...
-
(2003)Surface tension measurements have been made in aqueous solutions of anionic hemiesters of an alternating copolymer of maleic acid and styrene, MAS-n with n=0-12, in the presence of dodecyltrimethylammonium bromide, DTAB. ...
-
(1983)The photochemistry of several phenyl alkyl and p-anisyl alkyl ketones has been examined using laser flash photolysis and conventional quantum yield techniques. The methoxy-substituted ketones show higher activation energies ...
