From:Journal of Research of the National Institute of Standards and Technology (Vol. 107, Issue 4) Peer-ReviewedLight scattering is used by semiconductor manufacturers to inspect silicon wafers for particulates, defects, and surface roughness. Since a particle's size determines its potential to cause device failure, it is...

From:Science (Vol. 264, Issue 5167) Peer-ReviewedThe spatial distribution of small translucent droplets inside a 50-millimeter-thick Intralipid solution was imaged with a picosecond time and spatial-gated Kerr-Fourier imaging system at a signal level of about 10-10 of...
-
From:Polymer Engineering and Science (Vol. 42, Issue 10) Peer-ReviewedLight scattering has proved itself an efficient technique to determine particle diameters in heterogeneous dilute dispersions in the micrometer range. Extrusion of polymer blends is expected to give rise to very small...

From:PLoS ONE (Vol. 12, Issue 12) Peer-ReviewedBackground Iron deficiency (ID) may impair long-term neurological development when it occurs in young infants. In cohort studies, it is sometimes necessary to evaluate ID with sera kept frozen for several years. To...

From:Journal of Research of the National Institute of Standards and Technology (Vol. 107, Issue 3) Peer-ReviewedNIST scientists have recently implemented a Brillouin light scattering facility for characterizing acoustic and magnetic waves in thin-film and bulk materials. This system is capable of measurements in the 3 GHz to 300...

From:Bulletin of the South Carolina Academy of ScienceLight scattering occurs when light waves encounter materials with varying index of refraction. Mie scattering occurs when the scattering particles are approximately the same size as the wavelength of light. Visible...

From:Proceedings of the Estonian Academy of Sciences (Vol. 64, Issue 3) Peer-ReviewedBased on ray tracing approach, light propagation in inhomogeneous media with fluctuating coefficient of refraction n = n(r) can be interpreted as a chaotic mixing of the wavefront in the 6-dimensional phase space where...
-
From:Science (Vol. 285, Issue 5427) Peer-ReviewedRayleigh scattering off a Bose-Einstein condensate was studied. Exposing an elongated condensate to a single off-resonant laser beam resulted in the observation of highly directional scattering of light and atoms. This...

From:Polymer Engineering and Science (Vol. 49, Issue 5) Peer-ReviewedEthylene-vinyl acetate copolymers with vinyl acetate (VA) contents of 9 wt% (EVA9) and 18 wt% (EVA18), and commercially modified montmorillonite clay were melt blended in a twin-screw extruder to produce nanocomposites...
-
From:Advances in Condensed Matter Physics (Vol. 2018) Peer-ReviewedHere we present measurements on the gel time of inorganic-organic materials used for stone preservation by means of rheology and dynamic light scattering. Our hybrid material is composed of tetraethyl orthosilicate...

From:Nature (Vol. 471, Issue 7340) Peer-ReviewedInelastic light scattering spectroscopy has, since its first discovery (1,2), been an indispensable tool in physical science for probing elementary excitations, such as phonons (3), magnons (4) and plasmons (5) in both...
-
From:Nature (Vol. 491, Issue 7423) Peer-ReviewedAnyone who has adjusted the sensitivity settings of a camera in weak light will have noticed that increasing the electronic gain of the camera's light sensor yields images of poor quality. This observation reveals a...
