Magnetostatic Fields in Multilayer Composite Films with a Bimodal Granule Size Distribution

Origin of the bimodal island size distribution in ultrathin films of para-hexaphenyl on mica

Ultrathin films of para-hexaphenyl (6P ) were prepared on freshly cleaved and sputter-amorphized mica(001) by physical vapor deposition. Ex situ atomic force microscopy (AFM) revealed a bimodal island size distribution for the films on both surfaces. On freshly cleaved mica long needlelike islands exist, which are surrounded by small crystallites. On the sputter-amorphized substrates, large den...

Bimodal Size-distribution of Bainite Plates

There are two well-known phenomena associated with the bainite reaction, both of which have been exploited here to enhance the mechanical behaviour of steel. Firstly, the bainite plate size decreases as the transformation temperature is reduced. Secondly, it is bad to have large regions of untransformed austenite in the microstructure; this is because they can transform, under the influence of ...

Quantum Size Effect in Conductivity of Multilayer Metal Films

Multilayer Nano Films for Corrosion Control

Nano films consisting of an alternating sequence of positively and negatively charged polyelectrolytes have been prepared by means of the electrostatic layer-by-layer (LBL) sequential assembly technique on treated and untreated mild steel wires. Inhibitor was encapsulated between cationic and anionic polyelectrolyte nano films. This paper mainly focuses on the effect of these nano-films of poly...

Fluid-fluid phase separation in hard spheres with a bimodal size distribution

– The effect of polydispersity on the phase behaviour of hard spheres is examined using a moment projection method. It is found that the Boublik-Mansoori-Carnahan-StarlingLeland equation of state shows a spinodal instability for a bimodal distribution if the large spheres are sufficiently polydisperse, and if there is sufficient disparity in mean size between the small and large spheres. The sp...
