We report the XPS characterization of a thin film of Al2O3 (35 nm) deposited via e-beam evaporation onto silicon (100). The film was characterized with monochromatic Al Kα radiation. An XPS survey scan, an Al 2p narrow scan, an O 1s narrow scan, and

In this paper, a systematic study is provided of the chemical environment inside free volume holes in a series of halogenated polystyrenes (p-position), −[CH2CH C6H5X]n– (X = F, Cl, Br, I), by using positron annihilation spectroscopy. In such pol

A squaraine−cholesterol diad, 1, which has been found to be a good gelator, has been studied in films at the air−water interface and in supported Langmuir−Blodgett films. Both experimental observations and simulations are consistent with a low-

The aggregation of the cyanine dye, 3,3’-disulfobutyl-5,5’-dichloro thiacarbocyanine triethylamine, (NK-3796) in aqueous solution was investigated using absorption and emission spectroscopy. The equilibrium, n(monomer) ⇆ n(dimer) ⇆ (H-aggrega

Monolayer and multilayer Langmuir-Blodgett (LB) films of the neutral hydrophobic Ir(ppy)[sub 3] (1) (ppy = 2-Phenylpyridine) have been produced on the water surface when mixed with a fatty acid (stearic acid). The molecular area of the complex in the

The molecular distribution of the cyanine dye (5-chloro-2-[3-[5-chloro-3-(4-sulfobutyl)-2(3H)-benzothiazolylidine]-1-propenyl]-3-(4-sulfobutyl)-benzothiazolium hydroxide triethylamine salt, NK-3796) in aqueous solution was investigated using absorpti
