Removal of the deposition on JT-60 tile by nano-second pulsed-laser irradiation
To clarify the property of tritium removal from carbon codeposition by using pulsed-laser induced desorption, hydrogen removal from co-deposits on JT-60 divertor tile using a fourth-harmonic emission (266 nm) of a nano-sec Nd:YAG laser was demonstrated. The threshold laser fluence for ablation was ~ 0.3 J/cm, which was slightly higher compared to that of the pico-sec laser irradiation. The ener...
متن کاملNear-field thermal transport in a nanotip under laser irradiation.
We report on a systematic study of highly enhanced optical field and its induced thermal transport in nanotips under laser irradiation. The effects on electric field distribution caused by curvature radius, tip aspect ratio, and polarization angle of the incident laser are studied. Our Poynting vectors' study clearly shows that when a laser interacts with a metal tip, it is bent around the tip ...
متن کاملReprogramming cell shape with laser nano-patterning.
Cell shape in vitro can be directed by geometrically defined micropatterned adhesion substrates. However conventional methods are limited by the fixed micropattern design, which cannot recapitulate the dynamic changes of the cell microenvironment. Here, we manipulate the shape of living cells in real time by using a tightly focused pulsed laser to introduce additional geometrically defined adhe...
متن کاملReshaping the Tips of ZnO Nanowires by Pulsed Laser Irradiation
Vertically aligned ZnO nanowires have been synthesized by a hydrothermal method. After being irradiated by a short laser pulse, the tips of the as-synthesized ZnO nanowires can be tailored into a spherical shape. Transmission electron microscopy revealed that the spherical tip is a single-crystalline piece connected to the body of the ZnO nanowire, and that the center of the sphere is hollow. T...
متن کاملPhotoisomerization of an azobenzene gel by pulsed laser irradiation.
A decalin gel consisting of a 3,3'-bis[{(octylamino)carbonyl}propoxy]azobenzene derivative with H-aggregation showed a photon-density dependent E-Z isomerization, indicating the cooperating isomerization of each module.
