Abstract Nanometric metallic stripes allow the transmission of optical signals via excitation and propagation surface-localized evanescent electromagnetic waves, with important applications in field nano-photonics. Whereas this kind plasmonic phenomena typically exploits noble metals, like Ag or Au, other materials can exhibit viable light-transport efficiency. In work, we demonstrate transport...
Acoustic vibrations in tissue are often difficult to image, requiring high-speed scanning, high sensitivity and nanometer-scale axial resolution. Here we use spectrally encoded interferometry to measure the vibration pattern of two-dimensional surfaces, including the skin of a volunteer, at nanometric resolution, without the need for rapid lateral scanning and with no prior knowledge of the dri...
We report on a study of the nanocrystalline structure in Ti, which was produced by cryogenic milling followed by subsequent consolidation via severe plastic deformation using high pressure torsion. The mechanisms that are believed to be responsible for the formation of grains smaller than 40 nm are discussed and the influence of structural characteristics, such as nanometric grains and oxide na...
In view of better characterizing possible quantum effects in the dynamics of nanometric particles, we measure the effect on the relaxation of a slight heating cycle. The effect of the field amplitude is studied; its magnitude is chosen in order to induce the relaxation of large particles (∼ 7nm), even at very low temperatures (100mK). Below 1K, the results significantly depart from a simple the...
ABSTRACT We proposed hybrid nanorobot that can be manipulated by optical tweezers and has hybrid structure integrating functional nanomaterials. We employed femotosecond laser exposure for fabrication of the nanorobot with 3D nanometric structure. We succeeded in fabricating nanorobot with carbon nanotubes (CNTs) that has a high photothermal efficiency. Furthermore, we evaluated optical manipul...
Nanometric titanium dioxide (TiO2) powder has been treated on the surface with octyltriethoxysilane in a supercritical carbon dioxide (scCO2) medium. The surface silanization conferred water repellency to the TiO2 powder. The effect of operating variables of the supercritical silanization process (pressure, temperature) on the surface characteristics of the material was analyzed. Finally, the e...
