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 ...

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 ...

Layer-by-layer surface modification of lipid nanocapsules
European Journal of Pharmaceutics and Biopharmaceutics, 2010Lipid nanocapsules (LNCs) were modified by adsorbing sequentially dextran sulfate (DS) and chitosan (CS) on their surface by the layer-by-layer (LBL) approach. Tangential flow filtration (TFF) was used in intermediate purifications of the LNC dispersion during the LBL process. The surface modification was based on electrostatic interactions between the

Planetary boundary layer and surface layer sensitivity to land surface parameters
Boundary-Layer Meteorology, 1996The sensitivity of the development of the convective planetary boundary layer (PBL) and the surface layer are examined using a coupled surface parameterization and detailed PBL model. First, the coupling is verified against observations from the First ISLSCP (‘International Satellite Land Surface Climatology Project’) Field Experiment (FIFE).

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

Unpolymerized Surface Layers on Sealants
Acta Odontologica Scandinavica, 1981Oxygen inhibits radical polymerization, and for the present investigation, the thickness of the resulting unpolymerized surface layer on various proprietary dental polymers was measured by a microscopic technique. The inhibition depth of the polymerized resins varied from 7 to 84 micrometers.

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 ...

Purification of Tannerella forsythia Surface-Layer (S-Layer) Proteins
2020The objective of this chapter is to provide a detailed purification protocol for the surface-layer (S-layer) glycoproteins of the periodontal pathogen Tannerella forsythia. The procedure involves detergent based solubilization of the bacterial S-layer followed by cesium chloride gradient centrifugation and gel permeation chromatography. The protocol is
