A nanoparticle composed of a [gold] metallic shell surrounding a semiconductor.  7, record 1, English, - gold%20nanoshell

Record number: 1, Textual support number: 1 OBS

When nanoshells reach a target cancer cell, they can be irradiated with near-infrared light or excited with a magnetic field, either of which will cause the nanoshell to become hot, killing the cancer cell.  7, record 1, English, - gold%20nanoshell

Record number: 1, Textual support number: 1 CONT

This chemical sensing technique relies on nanoparticles consisting of gold and silica called nanoshells, invented 10 years ago at Rice by nanophotonics pioneer Naomi Halas. Nanoshells are about 20 times smaller than a red blood cell, and they can amplify light waves and focus them so tightly that scientists can use them to detect just a few molecules of a target chemical. Building catalysts directly on the surface of the nanoparticles themselves allows researchers to use the nanosensing capabilities of nanoshells to directly follow chemical reactions on the catalyst using light.  8, record 1, English, - gold%20nanoshell

The laser gyro need not be mechanically dithered. The same result may be achieved by optical devices. A Faraday cell is a piece of crystal, which changes the phase of a light wave traveling through it as a function of an applied magnetic field. The effect is nonreciprocal. A light beam traveling in one direction is advanced in phase, while a light beam traveling in the other direction is retarded in phase. Reversing the magnetic field reverses the effect. Changing the phase of the light beam has the same effect on frequency as changing the path length.

[...] si le rayon de Larmor de la particule est tel qu'il existe des valeurs de l'angle pour lesquelles la relation (3.16) est vérifiée, la particule subira alors une déflection qui fera varier son angle d'attaque, entraînant du même coup une déviation de sa trajectoire originelle. Le processus alors engagé amènera la particule à rencontrer d'autres résonances qui entraîneront alors une marche au hasard pour la particule. Cette marche au hasard est la base du processus diffusif qui veut qu'une particule perde rapidement le souvenir de sa trajectoire initiale. L'exemple présenté ici est évidemment simpliste (la relation 3.16 n'est pas [toujours valide]). Néanmoins, dans le cas des champs magnétiques chaotiques à trois dimensions, l'idée de résonance reste. Ainsi, il faudra que la particule suive une relation similaire à (3.16) pour qu'elle rencontre des résonances avec le chaos. Si le rayon de Larmor d'une particule est très inférieur (ou supérieur) à la plus petite longueur d'onde du champ chaotique, elle ne subira pas d'effets de diffusion spatiale ou angulaire.  3, record 20, French, - cheminement%20al%C3%A9atoire

Strictly speaking the beads are not magnetic but superparamagnetic : they have no magetic "memory, and thus, after exposure to a magnetic field, can be redispersed without aggregation.
