Summary: Aluminum-doped zinc oxide (AZO) films were synthesized using reactive high power impulse magnetron sputtering (HiPIMS) at various Al contents. Investigations on film structure, microstructure, and electrical properties revealed that increasing Al content led to the evolution of film structure and microstructure, and effective doping could be achieved up to 3 at.% Al using HiPIMS.

Summary: Transparent amorphous Sn-Al co-doped ZnO thin films were prepared using a sol-gel spin-coating technique. The films exhibited a combination of two different amorphous phases, with the dominant phase showing high near ultraviolet transparency and ultrawide bandgap, while the minor phase had low transparency and bandgap. Control of the amorphous structure allowed for achieving desired properties such as near ultraviolet transparency and bandgap, with the lowest resistivity found at a specific Sn-Al concentration. The a-SAZO films with low resistivity have the potential to replace a-IGZO films in certain applications.

Summary: This paper discusses the kinetics of growth and electronic properties of filled carbon nanotubes using spectroscopy for applications. It starts with the discussion of growth of carbon nanotubes inside metallocene-filled carbon nanotubes. Then, four spectroscopic techniques are used to investigate the filled carbon nanotubes. The results show that different substances lead to changes in electronic structure of the nanotubes and offer promising applications.

Summary: Noble-transition metal alloys have emergent optical and electronic properties for near-infrared optoelectronic devices. The investigation on CuxPd1-x alloy thin films reveals that their optical and electronic properties can be tuned by ultrafast electron dynamics under near-infrared excitation. Hybridization effects in dilute Pd alloys result in emergent optical properties, while thermalization effects are observed in Pd-rich alloys upon ultrafast near-infrared photoexcitation.

Summary: In this study, thin films of undoped ZnO, ZnO doped with Al, ZnO doped with Cu, and co-doped ZnO with Al and Cu were deposited on quartz substrates using RF sputtering. The samples were investigated for their advanced fractal features, crystalline structure, and optical properties. The results showed that the films had different morphologies and transmission spectra, with the co-doped sample exhibiting the highest transparency in the visible region and a desirable band gap.

Summary: The study unveils the strategy of Cl-Yb3+ charge transfer sensitization in Ln(3+)-doped Cs2NaInCl6 DPs, resulting in efficient NIR luminescence of Ln(3+). The localized electrons of [YbCl6](3-) octahedron in Cs2NaInCl6 DPs facilitate the Cl-Yb3+ charge transfer process. The mechanism of Cl-Yb3+ charge transfer sensitization is verified by spectroscopic experiments and theoretical calculations. Furthermore, the efficient NIR emission of Er3+ is also realized using the same strategy. These findings provide fundamental insights for optical manipulation of Ln(3+)-doped halide DPs.

Summary: The tunability of vanadium dioxide's complex dielectric constants makes it a promising phase-change material for active and dynamic photonics applications. By doping vanadium dioxide with tungsten, the transition temperature of the material can be reduced to room temperature, allowing for further tunability. In this study, we investigated tungsten-doped vanadium dioxide thin films and achieved perfect absorption at different temperatures, demonstrating the potential for thermo-optical devices.

Summary: In this study, MnO2 nanorods coated tea bag filter paper were developed as a self-standing, bendable, and disposable electrochemical probe for sensitive and selective H2O2 detection. By addressing challenges in H2O2 sensing and utilizing core@shell architecture with MoS2, the MnS@MoS2/TBFP probe showed low detection limit, excellent sensitivity, and wide linear range for H2O2 detection. The non-enzymatic H2O2 detection performances of MnS/MoS2/TBFP were found to be selective, decisive, repeatable, and stable, making them promising for practical applications.

Summary: This study investigates the plastic strain distribution of cold spray Cu powders and coatings using electron backscatter diffraction (EBSD) analysis. It is found that more dynamic recrystallization and plastic strain release occur in the as-sprayed EP and GA coatings compared to the WA coating. The influence of recrystallization of twin grains in the GA coating on the ductility of the coating is discussed. The static recrystallization in the postannealing treatment is more prominent in the EP and GA coatings, supporting differences in dynamic recrystallization among the cold-sprayed coatings determined through EBSD analysis. The thermal conductivity of cold-sprayed Cu coatings is affected by recrystallization and strain release.

Summary: When cold spraying is performed at a velocity equivalent to or greater than a material-dependent critical velocity, powders undergo plastic deformation and localized heating, leading to metallurgical bonding and/or mechanical interlocking. This study examined the characteristics of Cu feedstocks and their influence on the bonding strength of cold-sprayed Cu coatings. The results showed that annealing released plastic microstrains in Cu powders, and feedstock properties affected the resulting coating's ductility and hardness.
