The structure of the antimicrobial peptide NK-2 has been studied at the air-water interface and in different solutions using spectroscopic methods such as circular dichroism (CD) and infrared reflection absorption spectroscopy (IRRAS) as well as spec

Gas−liquid scattering experiments are used to explore the role of interfacial ions in controlling collisions and reactions of DCl molecules with ∼2.5 M KI, NaI, LiI, and NaBr glycerol solutions. DCl molecules that thermalize upon collision with t

The fate of DCl molecules striking pure glycerol and a 2.6 M NaI-glycerol solution is investigated using scattering, uptake, and residence time measurements. We find that dissolved Na+ and I- ions alter every gas-liquid pathway from the moment of con

Molecular beam scattering experiments are used to identify a submicrosecond, near-interfacial DCl → HCl exchange pathway following collisions of DCl with pure and NaOH-doped glycerol. We find that ∼7% of the thermally equilibrated DCl molecules u

Gas−liquid scattering, D → H exchange, and time-dependent uptake measurements are used to follow HCl, DCl, and HBr as they strike the surface of the neutral, hydrogen-bonding liquid glycerol. In this and the following paper, we report studies of

A new mechanism for spectral sensitization of silver halide is described, which can potentially double the sensitivity of photographic emulsions. The photooxidized sensitizing dye is trapped using an organic donor molecule, which fragments to form a

The primary process in conventional photography involves electron transfer from an excited dye molecule into the conduction band of a silver halide microcrystal. Repeated events of this type ultimately lead to formation of a small, stable cluster of

Femtosecond fluorescence upconversion was used to study the excited-state dynamics of two-dimensional J-aggregates of a thiacyanine dye. At high intensities the excited-state population decay is faster than exponential and the decay is intensity depe

Ammonia is arguably the most important alkaline trace species in the atmosphere. In addition to major ammonia sources on the ground, ammonium has been observed in aircraft exhaust that injects ammonia or ammonium directly into the upper troposphere.

The excited state dynamics of J-aggregated cyanine dyes adsorbed to silver halide microcrystals as spectral sensitizers were investigated. The rates of charge transfer, fluorescence, and non-radiative relaxation were studied as a function of surface
