Quenching of the first excited singlet state of anthracene (1An*) by nitromethane (NM) and 2-methyl-2-nitropropane (2M2NP) has been evaluated by picosecond, fluorescence-based methodologies in alka...

The fluorescence lifetime (τf) of trans-stilbene has been evaluated in zeolites Y and ZSM-5 under various conditions, e.g., at low temperature and in the presence of coadsorbed solvents. To make these measurements, an indirect method was developed t

Triplet excited states of pyrene, phenanthrene, and naphthalene have been prepared in zeolite KY by pulsed laser excitation and the influence of coadsorbed water on quenching of these triplet states by ferrocene and the immobile ferrocene derivative

Ultrathin films of polystyrene (PS) and poly(methyl methacrylate) (PMMA) coated on fused quartz plates (or slides) by dip coating are examined by using fluorescence spectroscopy. Cations of the pyrene derivative (4-(1-pyrenyl)butyl)trimethylammonium

Studies of Joule-discharge heating of packed beds of chemically modified silica gel address the influence of pore diameter, particle size, and chemical modification on the heating kinetics of the silica gel. The results reveal that surface modificati

Temperature-jump relaxation techniques are adapted to measuring the kinetics of reversible reactions at interfaces of liquid phases/solid phases. In the present work, we determine whether fast temperature changes can be created within a packed bed of

Spread phospholipid monolayers are particularly useful as model membranes in that changes in surface pressure (Deltapi) can be monitored in response to protein adsorption to the monolayer, thus providing a unique manner of assessing protein-membrane
