Abstract:
Nanometer sized materials can be produced by exposing a target to a laser source to remove material from the target and deposit the removed material onto a surface of a substrate to grow a thin film in a vacuum chamber.
Abstract:
Apparatuses and systems for submicron resolution spectral-domain optical coherence tomography (OCT) are disclosed. The system may use white light sources having wavelengths within 400-1000 nanometers, and achieve resolution below 1 μm. The apparatus is aggregated into a unitary piece, and a user can connect the apparatus to a user provided controller and/or light source. The light source may be a supercontinuum source.
Abstract:
Nanoparticles may be formed on a substrate by mixing precursor solutions deposited by an inkjet printer. A first solution is deposited on a substrate from a first inkjet print cartridge. Then, a second solution is deposited on the substrate from a second inkjet print cartridge. The solutions may be printed in an array of droplets on the substrate. Nanoparticles form when droplets of the first solution overlap with droplets of the second solution. In one example, the nanoparticles may be gold nanoparticles formed from mixing a first solution of 1,2-dichlorobenze (DCB) and oleylamine and a second solution of gold chloride trihydrite and dimethyl sulfoxide (DMSO). The nanoparticles may be incorporated into optoelectronic devices.

Abstract:
Patterned multilayer films, such as those used in electronic devices, solar cells, solid oxide fuel cells (SOFCs), and solid oxide electrolysis cells (SOECs) may be deposited and annealed in a single tool. The tool includes an inkjet printer head, a heater, and a laser. The inkjet printer head deposits on a substrate either suspended particles of a functional material or solvated precursors of a functional material. The head is mounted on a support that allows the head to scan the substrate by moving along the support in a first direction and moving the support along a second direction. After the head deposits the material the heater evaporates solvent from substrate, and the depositing and heating may be repeated one or more times to form a patterned multilayer material. Then, a laser, microwave, and/or Joule effect heating device may be used to anneal the multilayer material to a desired pattern and crystalline state.
