Summary: FeCrAl oxide dispersion strengthened (ODS) steel is a promising cladding material for Generation IV nuclear reactors due to its superior properties. The morphologies, crystal structures, and metal/oxide interface structures of two FeCrAl ODS steels were studied. The dispersion morphology of oxides in the 3.7Al-0.1Ti-0.6Zr ODS steel was found to be better than that of the 3.3Al-0.5Zr ODS steel. The proportions of different oxides in the two ODS steels were characterized. The mechanisms of oxide formation, polymorphic transition, and strengthening in the ODS steels were discussed.

Summary: The study analyzed the coherent edge interface structures of thin {111}(Al) Omega plates in a peak-aged Al-Cu-Mg-Ag alloy using atomic-resolution STEM, finding that these edge interfaces can tilt from their orthogonal orientations to the broad plate surfaces. The edge interface tilts are correlated with shear component orientations along the broad plate surfaces and vary with plate thicknesses, while Cu atoms tend to occupy specific atomic sites near the edge interfaces in the Al matrix region.

Summary: The low-cycle fatigue behavior of single-phase, face-centered cubic CoCrNi and CoCrFeMnNi alloys at room temperature shows cyclic hardening followed by softening and a near steady state until failure. CoCrNi exhibits higher strength, lower inelastic-strain, and longer lifetime compared to CoCrFeMnNi. Microstructural investigations reveal no noticeable changes in texture, grain size, and twin fraction, but CoCrNi exhibits planar dislocation structures while CoCrFeMnNi shows well-defined wavy dislocation structures. This is attributed to CoCrNi's lower stacking fault energy, which enhances planar slip and delays deformation localization leading to superior fatigue resistance.

Summary: This study investigates the formation of boron carbide superhard particles through a liquid-phase reaction at high pressure and high temperature. The synthesized particles exhibit a rhombic hexecontahedron morphology with twelve five-vertex stars. Electron microscopy and X-ray diffraction were used to analyze the crystal structure of these particles, revealing multiple cycling twinning rather than quasi-crystalline symptoms. The specific shape of the particles is explained by the decrease of surface energy during formation at high pressure and high temperature.

Summary: This study demonstrates differences in high temperature embrittlement behavior between the base and weld metals of a 22% Cr duplex stainless steel, with the weld metal showing a more pronounced decrease in impact toughness and more significant hardening of ferrite in each layer. The accelerated spinodal decomposition of ferrite in the weld metal, particularly due to higher Ni content, resulted in faster embrittlement compared to the base metal.

Summary: Intermetallic phases in Mg-8Zn-6Al-1Sm alloys in both as-cast and peak-aged conditions were investigated. The study identified various intermetallic phases, such as Mg44Al15Zn41, Mg5Zn2Al2, Mg-32(Al,Zn)(49), and Al2Sm. Aging treatment showed a possible phase transformation and revealed precipitate constituents, including i phase, MgZnAl cubic phase, MgZn2 phase, Mg4Zn7 phase, and aperiodic structures. The study also found multiple orientation relationships between precipitates and the Mg matrix, and observed ordering planar faults in MgZn2 precipitates. The calculations demonstrated the superior strengthening effect of Mg-Zn-Al precipitates and attributed the high strength of the alloy to semi-continuous intermetallic skeletons and Mg-Zn-Al precipitates.

Summary: The temperature dependence of flexural strength in sintered boron carbide was investigated. At temperatures above 2000 degrees C, B4C displayed remarkably high flexural strength and a transition from brittle fracture to plastic deformation. Scanning transmission electron microscopy analysis revealed that the observed plasticity in B4C at high temperatures originated from microstructural amorphization.

Summary: Carrier-free curcumin nanoparticles (CFC NPs) were prepared by adding the DMSO solution of Cur into DI water under continuous rapid stirring. The CFC NPs exhibited a spherical shape with a diameter of 65.25 +/- 2.09 nm (PDI = 0.229 +/- 0.107) and a high loading capacity (LC) of 96.68 +/- 0.03%. Furthermore, the CFC NPs significantly improved the water dispersibility and release of Cur in vitro, and showed significantly enhanced DPPH radical scavenging activity. These results suggest that CFC NPs could be a promising vehicle for widening the applications of Cur in the food industry.

Summary: Chiral separation membranes have great potential for separating racemic mixtures into enantiopure components, but fabricating scalable membranes with both high selectivity and flux is challenging. In this study, a new type of enantioselective membrane was prepared using enantiopure S-poly(2,4-dimethyl-2-oxazoline) macromonomers and supported by graphene oxide nanosheets. The S-PdMeOx-based membrane showed near-quantitative enantiomeric excess and a high flux. This work demonstrates the potential of homochiral polymers in chiral discrimination and provides a new route to develop highly efficient enantioselective membranes.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
