X-Ray and Neutron Reflectivity
re = 2.818 × 10−15m is the classical electron radius, ρe is the electron density of the material, and μx is the absorption length. With δ > 0 we find that n < 1, which leads to the phenomenon of so-called total external reflection for incident angles αi below the critical angle αc = √ 2δ. Typical values for δ are 10−5 . . . 10−6, and thus αc is in the range of 0.1 ◦ . . . 0.5◦. For simplicity, ...
متن کاملStructural studies of the neural-cell-adhesion molecule by X-ray and neutron reflectivity.
The structures of adhesion proteins play an important role in the formation of intercellular junctions and the control of intermembrane spacing. This paper describes the combination of neutron and X-ray specular reflectivity measurements to investigate the structure of the ectodomain of the neural-cell-adhesion molecule (NCAM). The measurements with unmodified NCAM suggest the presence of a ben...
متن کاملMembranes at interfaces: structure studies by AFM and time-resolved neutron reflectivity.
Model biomembranes are either organized as vesicles or as planar bilayers. These represent two principally different model systems for the investigation of biophysical processes in single bilayers. Here we report on supported planar layers prepared by precipitation of lipid molecules from vesicles in a suspension [1], and on initial studies of small peptides interacting with such model membrane...
متن کاملAdsorption of Polystyrene Sulfonate to the Air Surface of Water by Neutron Reflectivity
The adsorption of the strong polyelectrolyte polystyrene sulfonate (PSS) to the air surface of dilute aqueous solutions was investigated as a function of molecular weight and salt concentration. Detailed segment profiles of the deuterated polymer were determined by neutron reflection. Surface activity was also examined through surface tension measurements. In general, the segment profiles are c...
متن کاملNeutron Reflectivity and Grazing Angle Diffraction
Over the last 10 years, neutron reflectivity has emerged as a powerful technique for the investigation of surface and interfacial phenomena in many different fields. In this paper, a short review of some of the work on neutron reflectivity and grazing-angle diffraction as well as a description of the current and planned neutron rcflectometers at NIST is presented. Specific examples of the chara...
