AbstractThe competitive adsorption of lung surfactant (LS) and albumin at the air-liquid interface and the ability of polyethylene glycol (PEG) to mediate LS adsorption are analyzed using pressure area isotherms and grazing incidence x-ray diffraction (GIXD). The addition of albumin drastically reduces the amount of LS on the interface and slightly increases the LS lattice spacing. The addition of PEG restores the characteristic LS peaks, yielding a slightly more compact lattice. The scattering results are consistent with recent work which proposed that albumin creates a physical barrier which eliminates LS adsorption and that PEG enhances LS adsorption but does not significantly change LS surface ordering.

Anodized Titanium

AbstractThin copper foils (100 micrometers thick) are produced by electrolysis on anodized titanium substrates. A sharp distribution of grain diameter is observed around 200 nanometers. The X-ray diffraction pattern shows a slight preferential orientation of the crystals with the (111) planes parallel to the substrate. This X-ray diffraction pattern evolves at room temperature. After 60 days, a preferential orientation of the (200) planes parallel to the substrate is observed. This effect is associated with the recrystallisation of the foil with growth of large copper grains (diameter higher than 5 micrometers) as observed by high resolution transmission electron microscopy.The structural evolution of the copper foils is studied by electron microscopy, X-ray and electron diffractions at different temperatures.The mechanical properties of the foils are also studied as a function of time after electrodeposition.

A series of CrTiN films were successfully deposited by medium frequency magnetron sputtering in a mixture gas of nitrogen and argon. X-ray diffraction analysis shows that the CrTiN have preferential orientation of (200). The films show low friction and low wear rate at a certain percentage of the Ti content.

Structure Properties

Liquid – liquid interface reaction is the method forpreparation nanoparticles (NP'S) which depend on the supersaturation of ions that provide by using the system that consist fromtoluene and water, the first one is above the second to obtainnanoparticles (NP's) CdS at the interface separated between thesetwo immiscible liquid. The structure properties were characterized byXRD-diffraction and transmission electron microscopy.The crystalline size estimate from X-ray diffraction patternusing Scherer equation to be about 7nm,and by TEM analysis give usthat ananosize is about 5 nm which give a strong comparable withBohr radius. Photoluminescence analysis give two emission peak,the first one around the 380 nm and the second around the 760nmwhich indicate to the band edge and surface defect emissionrespectively and the intensity of these emission change with thechange of the pyridine substituent.

This study examined the chemical stability of malayaite pigments in ceramic glazes containing high amounts of zinc oxide (ZnO). The calcined pigments were embedded in a molten glaze which is basically corrosive glass. Within the glaze, ZnO has been known among potters to be undesirable as some pigments are not stable in glazes containing ZnO. The synthesized pigments’ particle size ranges from 4 to 18 μm without dominant preferential orientation. Their colors were in the red and yellow tones. Chemical stability between the pigments and glazes was tested using X-ray Diffraction (XRD). Slight changes were observed. Increasing amounts of ZnO resulted in an interfacial layer of approximately 50 μm between the crystalline pigment and surrounding amorphous glaze. The a color parameters gradually decreased while the b parameters switched to a negative value. The resulting glazes evolved from maroon to pale violet. The correlation between color and microstructural alterations was discussed.
