Dual-action self-healing protective coatings with photothermal responsive corrosion inhibitor nanocontainers

This work introduces a novel nanocomposite coating with dual-action self-healing corrosion protection activated by the photothermal response of plasmonic titanium nitride nanoparticles (TiN NPs). TiN@mesoporous SiO₂ core–shell nanocontainers were developed as reservoirs for benzotriazole (BTA) corrosion inhibitors and incorporated...

X-ray induced secondary particle counting with thin NbTiN nanowire superconducting detector

We characterized the performance of abiased superconducting nanowire to detect X-ray photons. The device, made of a 10 nm thin NbTiN film and fabricated on a dielectric substrate (SiO2, Nb3O5) detected 1000 times larger signal than anticipated from direct X-ray absorption. We attributed this effect to X-ray induced generation of secondary...

Fabrication and characterization of polyimide-based 'smooth' titanium nitride microelectrode arrays for neural stimulation and recording

OBJECTIVE: As electrodes are required to interact with sub-millimeter neural structures, innovative microfabrication processes are required to enable fabrication of microdevices involved in such stimulation and/or recording. This requires the development of highly integrated and miniaturized systems, comprising die-integration-compatible...

Deposition of conductive TiN shells on SiO2 nanoparticles with a fluidized bed ALD reactor

Conductive TiN shells have been deposited on SiO2 nanoparticles (10–20 nm primary particle size) with fluidized bed atomic layer deposition using TDMAT and NH3 as precursors. Analysis of the powders confirms that shell growth saturates at approximately 0.4 nm/cycle at TDMAT doses of >1.2 mmol/g of powder. TEM and XPS analysis showed that all...

Electrodynamics of strongly disordered superconductors

Thin films of superconducting materials with a high resistance in the normal state, such as TiN, NbTiN, NbN and InO, are intensively studied from both an application and a fundamental point of view. A spatially inhomogeneous superconducting state can arise in these materials as a result of the strong disorder. This Thesis provides an...

Characterization of metals for Cochlear Implants

The need for Cochlear Implants (CI's) with improved functionality and quality requires new techniques to be used to manufacture the electrode array. Titanium nitride (TiN) is one of the contenders for use as metal in the future CI's, but its characteristics need to be verified, measured and tested. A metal should comply to certain requirements...

Thin Titanium Nitride Films Deposited using DC Magnetron Sputtering used for Neural Stimulation and Sensing Purposes

n recent times Platinum (Pt), Iridium (Ir), Iridium oxide (IrO) and Platinum-Iridium (Pt-Ir) are the favorable microelectrode materials. They show excellent electrical and mechanical properties suitable for neural stimulation and sensing/recording purposes. But their long term stability and performance is still in question especially working in...
