Surface waves in chiral layers
Optics Letters, 1991We analyze the surface-wave propagation in homogeneous layers of chiral or optically active materials. Two cases of chiral slab are considered: a symmetric chiral slab waveguide and a grounded chiral slab waveguide. The dispersion relation and the electric-field components for surface waves guided in a symmetric chiral slab are analyzed and discussed ...

Viscosity of the ice surface layer
The Journal of Chemical Physics, 1980The thermal contraction of ice single crystals between 0 and −50 °C has been measured by the use of silicon strain gauges frozen on the crystal basal surface. The experimental results cannot be explained without assuming the existence of a Newtonian viscous layer at the ice-strain-gauge interface; this layer has a thickness which changes in temperature

The Cold Surface Layer on Storglaciaren
Geografiska Annaler. Series A, Physical Geography, 1989The thickness of the cold, water free surface layer was mapped using a high frequency radar. In the ablation area of Storglaciaren the layer was approximately 30 m thick.

Glycobiology of surface layer proteins
Biochimie, 2001Over the last two decades, a significant change of perception has taken place regarding prokaryotic glycoproteins. For many years, protein glycosylation was assumed to be limited to eukaryotes; but now, a wealth of information on structure, function, biosynthesis and molecular biology of prokaryotic glycoproteins has accumulated, with surface layer (S ...

Diffusion in the diabatic surface layer
Journal of Geophysical Research, 1962Diffusion from point and line sources in an adiabatic surface layer were briefly discussed using a similarity method by Ellison, following a suggestion made at the 1958 Oxford Symposium by Batchelor. The chief result is that the ground concentration at a downwind distance x, from a point source at ground level, is found to be proportional to xm, where ...

Layer-By-Layer Oxidation of Silicon Surfaces
MRS Proceedings, 1999ABSTRACTLayer-by-layer oxidation of Si(111) and (001) surfaces has been studied by using scanning reflection electron microscopy (SREM). We found that SREM images reveal interfacial structures of the SiO2/Si system. Our results showed that the initial step structure of Si substrates was preserved at SiO2/Si interfaces and that interfacial steps did not

Surface reconstruction in layer-by-layer sputtering of Si(111)
Physical Review B, 1991Using scanning tunneling microscopy, we have investigated vacancy-mediated, layer-by-layer removal of surface atoms from Si(111) under 225-eV Xe-ion bombardment. We observe, with increasing substrate temperature, both the transition from vacancy-cluster nucleation to step retraction, and a transition from disruption to preservation of the 7\ifmmode ...

Construction of Antibacterial Surface Via Layer-by-Layer Method
Current Pharmaceutical Design, 2018Construction of antibacterial surfaces or films is of great interest in various fields including biomedicine, food, agriculture and so on. So far, a number of antibacterial agents have been used to construct antibacterial surfaces. Layer-by-Layer (LbL) assembly is a simple and versatile deposition process for fabricating multilayer thin films with ...
