Summary: A simple and efficient approach for the synthesis of Cr2O3 coated carbon nanotubes (CNTs) was developed, and the morphologies and microstructures of the coating on CNTs were investigated at different annealing temperatures. The findings showed that the amorphous (Cr2O3)(1/2)•(H2O)(3/2) coating can be transformed into amorphous Cr2O3 coating after annealing, and then into nano Cr2O3 particles with high crystallinity. The research provides important guidance for the surface modification of CNTs and lays the foundation for the industrial application of Cr2O3 coated CNTs.

Summary: This paper presents a new method to modify the surfaces of pristine multiwall carbon nanotubes (CNTs) by acid treatment, silanization, and grafting of AlN nano-particles, which enhances the dispersion uniformity, wettability, and matrix-reinforcement bonding strength in liquid metallurgy processed aluminium matrix composites (AMCs). The effectiveness of AlN nano-particle grafting is demonstrated through various characterization techniques, such as dispersion stability test, spectroscopy analysis, X-ray diffraction, and electron microscopy. The results confirm the improved dispersion stability, covalent attachment of AlN nano-particles onto CNT surfaces, and the existence of AlN on the CNT sidewalls.

Summary: This study investigates the spatial distribution of carbon nanotubes (CNTs) in an aluminum matrix and reveals that the length-scale, thermal activation, and external applied stress play important roles in controlling the location of CNTs. The results demonstrate that long CNTs are mainly located at the grain boundaries, while short CNTs enter the grain interiors with the synergy of thermal activation and external applied stress. The understanding of these mechanisms provides valuable insights for achieving precise control over the distribution of CNTs in composites.

Summary: In this study, titanium surface was reinforced with carbon nano tubes (CNTs) for the first time through friction stir processing to produce nanocomposites for biomedical applications. By increasing the number of passes, the strength and hardness were increased due to formation of finer CNTs distributed uniformly in fine dynamically recrystallized grains. The optimum condition, which maximizes both the strength and ductility, was achieved at two numbers of passes.

Summary: In this study, we created a heterojunction by joining a silver nanostructure film and a carbon nanotube film using van der Waals force. The heterojunction exhibited excellent photothermal and photoelectric conversion properties. When irradiated by lasers with wavelengths ranging from ultraviolet to terahertz, the heterojunction showed a rapid increase in local temperature difference and output photovoltage. The maximum temperature difference achieved was significantly higher than that of other photothermoelectric materials reported in the literature. The photothermal and photoelectric responsivity depended on the wavelength of the lasers, with values of 175-601 K W-1 and 9.35-40.4 mV W-1, respectively. Our findings demonstrated that light absorption of the carbon nanotube was enhanced by local surface plasmons, and the output photovoltage was dominated by the Seebeck effect. The proposed heterostructure has potential applications as high-efficiency sensitive photothermal or ultra-wideband fast-response photoelectric materials.

Summary: A study was conducted on the post-weld microstructure, hardness profile, and uniaxial tensile behavior of a transformation-induced plasticity (TRIP) steel and a dual-phase (DP) steel that were welded using gas metal arc welding (GMAW) and laser beam welding (LBW) processes. The results showed that the LBW specimen exhibited better elongation properties and higher ultimate tensile strength (UTS) compared to the GMAW specimen. The residual stress distribution along the weldment was also analyzed, with the LBW specimen showing lower residual stresses compared to the GMAW specimen. Furthermore, the tensile residual stresses in both welding processes did not affect the overall tensile properties of the weldments.

Summary: Ultrabroadband photodetectors (PDs) spanning from UV to THz frequency range are crucial for integrated multifunction photoelectric detection. However, a lack of high-performance PDs hampers the overall development in this field. In this study, a high-performance ultrabroadband PD with a composite nanostructure is demonstrated, utilizing carbon nanotube film decorated with titanium and palladium nanoparticles for n-doping and p-doping, respectively. This PD exhibits short response time, high responsivity, large linear dynamic range, and small noise equivalent power, based on the photothermoelectric effect.

Summary: Solution-processed colloidal quantum dots (CQDs) are promising materials for short-wavelength infrared (SWIR) photodetectors. However, the low carrier mobility of CQD-based hole transport layers (HTL) limits the photodiode response speed. By employing NiOx as the HTL in inverted SWIR photodetectors, we achieve 4x shorter fall times compared to CQDs treated with 1,2-ethanedithiol (EDT). Optoelectronic simulations show that the high carrier mobility of NiOx enhances the electric field in the active layer, reducing transport time and increasing photodetector response time.

Summary: By introducing polyethylene oxide (PEO) polymer into PbBr2 solution as a ligand, the formation of CsPbBr3 films is modified, resulting in the evolution of microstructure from small grains to equiaxed large grains with preferred crystallographic orientation. The improved quality of CsPbBr3 films leads to low defect density and prolonged carrier lifetime, which boosts the efficiency of carbon-based hole transportation layer (HTL) free solar cells from 5.92% to 8.12% by optimizing the volume fraction of PEO in PbBr2 solution.

Summary: It is believed that high-entropy alloys (HEAs) have great potential in cryogenic and aerospace applications. However, there is still much to be explored due to the vast design space available for HEAs. This review focuses on four less addressed areas of HEA applications, including joining technologies, HEA nanomaterial synthesis, catalysis, and marine applications. The performance of HEAs as filler metals and base metals in welding and brazing is discussed, along with various methods for synthesizing HEA nanomaterials and their applications in catalysis and energy storage. Furthermore, the corrosion resistance and antifouling properties of HEAs make them intriguing materials for marine applications.
