Summary: Establishing a platform with different nanostructured oxides is a novel idea for developing highly sensitive and selective sensing devices. The study successfully created 3D-heterostructures consisting of 1D nanowires of NiO and WO3, exhibiting selective behavior towards different gases. The improved sensing performance of the heterostructures is attributed to charge carrier transport through specific interfaces and modulation of charge carriers in the electron depletion layer of WO3 and hole accumulation layer of NiO and NiWO4.

Summary: An experimental analysis was conducted to optimize the structure of Ni-Ni(OH)(2)/NiO core-shell nanowire electrodes for pseudocapacitor applications. The thickness and composition of the active phase shell were found to be affected by thermal treatments at different temperatures, resulting in varying capacitance values. Tailoring the capacitance of the electrodes by controlling the nanowire length was evaluated, showing that mass transfer resistance can be negligible within a certain range.

Summary: Using plasma-synthesized ultrafine Si nanoparticles as an energetic filler in biocidal nanothermite composites shows potential to increase energy density by approximately 21% and enhance combustion performance. However, at nSi loadings higher than 8%, slower burning characteristics of nSi and sintering effects lead to an overall degradation of combustion behavior in the composites.

Summary: Dyes are widely used synthetic organic compounds in various industries, but the effluents released into water bodies cause pollution worldwide. Current methods for reducing toxic compounds in industrial effluents, such as physical, chemical, and biological approaches, are expensive and complex. However, the use of green-synthesized metal/metal oxide nanoparticles from plant extracts provides a cheap, non-toxic, and eco-friendly approach for the photocatalytic degradation of dye effluents.

Summary: This study compared the stress-strain curves obtained through hardness-scaling and ball-indentation techniques to simulate and predict the stress/strain distribution and failure behavior of resistance spot welded joints. The results showed that both methods can accurately predict the failure location, but the ball-indentation method provides slightly better predictions of failure behavior compared to the hardness-scaling method. However, the hardness-scaling method is a simple and convenient technique, which can serve as a qualitative analysis for the failure behavior of resistance spot welded joints.

Summary: The study found that the surface conditions and initial microstructures obtained through continuous galvanizing process have a significant impact on the mechanical properties and failure behavior of resistance spot welded advanced high-strength steels. Formation of internal oxides during annealing and subsequent coating process reduces heat input during resistance spot welding, leading to smaller nugget size and lower tensile-shear peak load values. Nugget size does not control failure location during lap-shear loading, but affects nugget load-carrying capability, and failure behavior is controlled by microstructural characteristics of different weld regions.

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: Advanced high-strength steels (AHSSs) are difficult to join using fusion welding processes. Weld-brazing offers a solution with lower heat input and reduced welding defects. This study shows that weld-brazed joints can be used for load-bearing applications with the right type of Zn-coated steel and proper joint geometry. The type of Zn coating and root geometry are the main factors influencing joint strength and fracture mode.

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.
