We report on the use of the self-organization process of sputtered gold nanoparticles on a self-assembled block copolymer film deposited by horizontal precipitation Langmuir-Blodgett (HP-LB) method. The morphology and the phase-separation of a film of poly-n-butylacrylate-block-polyacrylic acid (PnBuA-b-PAA) were studied at the nanometric scale by using atomic force microscopy (AFM) and Time of...

We investigated the magnetic properties of thin film samples with different number of layers stacked by the LB technique. The film samples showed a magnetically complex behavior in low temperature region, which is insufficiently explained by the idea of the homogenous dipole interaction field analogous to the demagnetizing field. The film thickness dependent behavior is discussed in terms of a ...

We first observed an unique pyrene (Py) emission from 10-(1-(6-hexyl)pyrenyl)decanoic acid (1,6-HPDA) Langmuir-Blodgett (LB) films. In the fluorescence spectra of the 1,6-HPDA LB films, the normal bands of monomer and excimer emission of Py were absent but the new structured emission band with peaks at Manuscript

Langmuir-Blodgett type polypeptide monolayers have been irradiated under conditions simulating the hazards of electron microscopic imaging. The damaging effect, i.e. the randomization of the alpha-helical layers, which occurs in the dose range between 50 and 200 e-/nm2, has been monitored by infrered dichroism.

Optical second harmonic generation (SHG) is used as a noninvasive probe of two-dimensional (2D) ferroelectricity in Langmuir-Blodgett (LB) films of copolymer vinylidene fluoride with trifluorethylene. The surface 2D ferroelectric-paraelectric phase transition in the topmost layer of LB films and a thickness independent (almost 2D) transition in the bulk of these films are observed in temperatur...
