Summary: This study focuses on quantifying the impact of microstructure on the functionality of titanium dioxide films caused by minor changes in the fabrication process. Thin titanium dioxide films are deposited using sputtering with variations in target composition and working environment. Various characterization techniques are employed to quantitatively analyze the phase, chemical constitution, composition, thickness, roughness, density, etc. of the films and their link to electronic structure, electrical, optical, and surface characteristics. The insights from this study can guide the experimental design for fabricating films with desired functionalities by considering the tolerance range.

Summary: (Ti-0.5, Mg-0.5)N thin films were synthesized by reactive dc magnetron sputtering, exhibiting a rock-salt cubic structure and a LiTiO2-type superstructure. The films have an electrical resistivity of 150 mΩ*cm and a Seebeck coefficient of -25 μV/K. High temperature annealing in a nitrogen atmosphere leads to the formation of the cubic superstructure. Density functional theory calculations show a 0.07 eV direct bandgap for the LiTiO2-type TiMgN2 structure.

Summary: This study conducted a systematic review to evaluate the effect of non-thermal plasma treatments on the adhesion of root canal sealers to dentin. Four studies were included in the analysis, with three using the push-out test in human extracted teeth and one using bovine dentin samples to measure the contact angle. The results suggested that non-thermal plasma might positively influence the adhesion ability of BioRoot RCS and Endosequence BC, but there was no consensus for AH Plus sealer. However, the scarcity of studies on this topic warrants caution in interpreting the findings.

Summary: Wet electrodes, which rely on conductive electrolyte gel, have issues such as long setup time, disposability or time-consuming cleaning, skin irritation, and signal quality deterioration. To overcome these drawbacks, 3D printed bases with polymers and functionalized with thin films of titanium and titanium-nitride, doped with copper, were developed. The results show that these dry electrodes have similar performance to wet AgCl/Ag electrodes for data acquisition, but improvements are needed for muscle stimulation and the durability and adhesion of the thin films.

Summary: The extinction efficiency of noble metal nanoparticles, such as gold and silver, depends on their size and the dielectric surrounding them. By exploiting the Localized Surface Plasmon Resonance (LSPR) phenomenon, the composition and structure of these nanoparticles can be tailored to optimize their sensitivity to environmental changes. Incorporating these nanoparticles into solid support in the form of nanocomposite thin films enhances the robustness of LSPR sensing. In this study, bimetallic films composed of gold, silver, and their mixture in a titanium dioxide matrix were grown using reactive DC magnetron sputtering. The LSPR response and sensitivity of the films were tunable by thermal treatment at different temperatures. The bimetallic film with an Au/Ag atomic ratio of 1 exhibited the highest refractive index sensitivity, showcasing the potential of bimetallic film systems in enhancing LSPR sensing.
