Summary: In this study, Cu-doped ZnO nanoparticles were synthesized and investigated to explore the mechanism of room-temperature ferromagnetism in these dilute magnetic semiconductors. The results showed that the 2% Cu-doped sample exhibited the highest oxygen vacancies and saturation magnetization. UV spectroscopy indicated a reduced band gap upon Cu doping. Photoluminescence spectroscopy and XPS results revealed the presence of defect-related states associated with Cu doping. The induced magnetization in the Cu-doped nano-crystalline samples was proposed to be caused by the exchange interactions between Cu2+ ions and oxygen vacancies.

Summary: In situ angle-dispersive X-ray diffraction study revealed that transition metal doping can significantly reduce the onset pressure of ZnO's pressure-driven phase transition from fourfold to sixfold structure. The transition path is influenced by the specific transition metal element. The doping-induced lattice distortion and the amount of 3d electrons carried by the transition metal atom both play important roles in the mechanism of the phase transition.

Summary: The study found that Co-doped SnO2 nanoparticles exhibit room-temperature ferromagnetism, with paramagnetic ordering gradually disappearing as the dopant concentration increases. An increase in Co content leads to a rapid increase in saturation magnetization of the system, while the coercivity of Co-doped SnO2 nanoparticles remains almost constant.

Summary: Multifunctional materials have attracted the attention of the global materials science community due to their ability to perform multiple tasks. In this study, CePO4:Sm3+ (CPOS) phosphor was demonstrated to be suitable for white light emission and oxygen reduction catalysis. Raman spectroscopy confirmed the stabilization of the monoclinic phase in CPOS, while X-ray photoelectron spectroscopy revealed the presence of both Ce3+ and Ce4+ ions and surface oxygen. The doping of 1.0% Sm in CPOS showed the best electrocatalytic performance, with a higher concentration of surface Ce (IV) associated with oxygen.

Summary: Zinc oxide (ZnO) nanostructures with nanoparticle morphology were synthesized using [OMIM]Br ionic liquid as a solvent and template by ionothermal method. The effect of temperature on the properties of ZnO nanostructures was investigated, and it was found that higher annealing temperature in the ionic liquid resulted in ZnO nanoparticles with increased crystalline structure and enlarged band gap. The Z-scan technique was used to study the nonlinear optical (NLO) responses of the samples, and it was observed that ZnO samples prepared at higher temperatures and longer exposure time in [OMIM]Br ionic liquid exhibited greater NLO responses compared to Cu-doped ZnO.

Summary: In this study, ZnO nanoparticles are suggested to enhance performance and reduce variation in device switching parameters in resistive random-access memory (ReRAM) devices. The formation of ZnO nanoparticles is verified using transmission electron microscopy, x-ray diffraction pattern, and atomic force microscopy after annealing ZnO prepared via atomic layer deposition on HfO2. The diffusing of oxygen from HfO2 to ZnO nanoparticles during annealing is explained by the calculation results using density functional theory (DFT).

Summary: This paper reports on the room temperature ferromagnetism in Y-doped ZnO thin films grown by RF magnetron sputtering. Characterization techniques including XRD, Raman spectroscopy, XPS, FESEM, EDAX, photoluminescence spectroscopy, and EPR spectroscopy were used to study the crystal structure, electronic states, morphology, point defects, and magnetic properties of the films. It was found that zinc interstitial and oxygen vacancy defects play a crucial role in the ferromagnetic properties of Y-doped ZnO thin films. VSM analysis confirmed the ferromagnetic nature of the doped films, while the pure ZnO film exhibited diamagnetic behavior. A dual donor defect-assisted bound magnetic polaron model was proposed to explain the behavior of the Y-doped ZnO diluted magnetic semiconductor system. The results obtained were found to be reliable and reproducible.

Summary: The impact of oxygen concentration on the structural, optical properties, and device performance of Ga2O3 thin film was investigated by controlling the oxygen flow rate during deposition. Higher oxygen flow rate led to poorer crystalline quality, increased film roughness, and introduction of defects. Decreasing oxygen concentration resulted in an increase in optical bandgap, a decrease in blue band contribution, and reduced defect concentration, surface roughness, and interface states. These findings are significant for improving the quality of Ga2O3 films and their applications in device fabrication.

Summary: Field emission tip arrays (nanoFEAs) with sub-100 nm apices on single crystal cerium hexaboride (CeB6) surface were fabricated using focused ion beam (FIB) milling microtechnology. The surface morphology and field emission properties of the nanoFEAs were systematically characterized. The nanoFEAs, with sharp tips of approximately 50 nm in size, exhibited the lowest turn-on electric fields (2.0 V/μm), high current (>1 mA) at 6.7 V/μm, and stable emission current, making them promising candidates for field emission electronics applications.

This study investigates the influence of Ca2+ doping on CaxBi6-xFe0.5Co0.5Ti4O18 thin films. The results show that increasing Ca2+ doping leads to increased lattice distortion and internal stress. The film with a low doping concentration exhibits better performance, but no regular changes are observed in the magnetic properties.

Summary: A novel hybrid structure of g-C3N4/ZnO/Ti3C2 photocatalysts was designed to investigate their abilities for CO2 reduction. The heterojunction of g-C3N4/ZnO improved photogenerated carriers' separation, while the addition of Ti3C2 fragments facilitated the photocatalytic performance from CO2 to CO. As a result, g-C3N4/ZnO/Ti3C2 significantly increased CO production compared to pristine g-C3N4 and ZnO, attributed to the enhanced photogenerated charge migration by metallic Ti3C2. This work provides a guideline for designing efficient hybrid catalysts in renewable energy fields.

Summary: The SiC nanocomposite Mg-2(Si0.4Sn0.6)Sb-0.015/(y)SiC (0 <= y <= 0.01) with Sb doping were prepared using the vacuum induction levitation melting technique in conjunction with mechanical alloying and spark plasma sintering process. The microstructure and thermoelectric properties were systematically investigated. The hierarchical nanostructures for the samples are composed of point defects, SiC nanocomposite particles, coherent in-situ nanophases, and grains. The SiC nanocomposite cause a minor reduction in electrical performance, and the constructed hierarchical nanostructures significantly decreased the lattice thermal conductivities. The highest figure of merit value of 1.55 is obtained at 643 K for the y = 0.0075 SiC nanocomposite sample.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
