When platinum clusters are deposited on octahedral titanium dioxide nanoparticles, a photocatalyst is obtained that produces higher quantities of hydrogen and, more importantly, is much more stable than any other combination.
Advanced nanoengineering technique crafts intricate 3D plasmonic structures, offering new possibilities in light manipulation at the nanoscale, with wide-ranging applications in technology and biomedicine.
Be fast, avoid light, and roll through a curvy ramp: This is the recipe for a pioneering experiment. An object evolving in a potential created through electrostatic or magnetic forces is expected to rapidly and reliably generate a macroscopic quantum superposition state.
Researchers have introduced an upconversion plasmonphore platform to enable precise control over the polarisation of isotropic upconversion nanoparticles. This is achieved by coupling upconversion activators with carefully designed anisotropic gap plasmon mode-supported metasurfaces.
The achievement represents a major advancement towards technological innovations such as ultra-sensitive and super-resolution infrared imaging, as well as single-molecule vibrational spectroscopy.
