We report that individual metallic nanowires and nanoobjects can be assembled and welded together into complex nanostructures and conductive circuits by a new nanoscale electrical welding technique using nanovolumes of metal solder. At the weld sites, nanoscale volumes of a chosen metal are deposited using a sacrificial nanowire, which ensures that the nanoobjects to be bonded retain their stru...

During electrochemical carbon dioxide (CO2) reduction on copper electrodes in an aqueous electrolyte, one of the key challenges is competition between hydrogen evolution and CO2 reduction, especially under large current density. Here, micro-electrodes are designed with a wire as substrate, which shows improved mass transport compared to planar electrode. The Faradaic efficiency for C2+ products...

The optical properties of organic semiconductor thin films deposited on nanostructured surfaces are investigated using time-resolved two-photon photoluminescence (PL) microscopy. The surfaces consist of parallel aligned metallic or dielectric nanowires forming well-defined arrays on glass substrates. Keeping the nanowire dimensions constant and varying only their spacing from 40 to 400 nm, we s...

Nanowire is a cylindrical nano-structure with nanometer dimensions. In this research, the studied nanowire was made from the magnetic triple Ni-Fe-Co alloy. We utilized ordered porous anodic aluminum oxide as a template for the nanowire deposition. The nanowire arrays were electrodeposited in the cylindrical pores of the oxide layer by AC potential in a simple sulfate bath. Then the relation ...

Excitation of surface plasmons in a single silver nanowire using higher-order-mode light shows that nanowire waveguide has no request on the spatial mode of the input light, which is determined by its orbital angular momentums (OAM) in the experiment. The excitation efficiency can be controlled by adjusting the light polarization. Experimental result also indicates that the propagating modes of...
