Abstract: This invention is directed to direct write printed reflective features comprising metallic particles and/or metallic nanoparticles. Preferably, the reflective feature are formed by a direct-writing printing process, e.g., a piezo-electric, thermal, drop-on-demand or continuous ink jet printing process, using an ink comprising metallic particles, e.g., metallic nanoparticles. The invention is also directed to inks suitable for printing such reflective features using a direct write printing process and to processes for making such reflective features.

Abstract: The invention is to printed resistors and processes for forming same. The resistors comprise a conductive phase, preferably comprising conductive nanoparticles, and a resistive phase. In the processes of the invention, a resistor may be formed from a single ink or a plurality of inks. In the single ink embodiment, an ink is deposited which comprises a conductive phase precursor, a resistive phase precursor and a vehicle. The vehicle in removed and the conductive and resistive phase precursors are converted to a conductive phase and a resistive phase, respectively. In the multiple ink embodiment, a first ink comprising the conductive phase precursor and a first vehicle and a second ink comprising the resistive phase precursor and a second vehicle are deposited on the substrate. The vehicles are removed and the conductive and resistive phase precursors are converted to a conductive phase and a resistive phase, respectively.

Abstract: The invention relates to a process for decreasing flame temperature in a flame spray reaction system, the process comprising the steps of providing a precursor medium comprising a precursor to a component; flame spraying the precursor medium under conditions effective to form a population of product particles; and decreasing the flame temperature by contacting the flame with a cooling medium. The process of the present invention allows for the control of the size, composition and morphology of the nanoparticles made using the process. The invention also relates to a nozzle assembly that comprises a substantially longitudinally extending atomizing feed nozzle that comprises an atomizing medium conduit and one or more substantially longitudinally extending precursor medium feed conduits. The nozzle assembly of the present invention is used in a flame spray system to produce nanoparticles using the processes described herein.
