Summary: Amosic-3 SiC/SiC composites were irradiated with 6 MeV Si ions at 300 degrees C to doses of 13 and 55 dpa, resulting in the loss of amorphous carbon packets and the growth of SiC grains. A mechanism based on grain growth theory was proposed to explain the relationship between carbon packet loss and SiC grain growth, with evidence from TEM images supporting the proposed mechanism.

Summary: The TiZrNb metal-matrix composites reinforced by in-situ formed borides were produced using different amounts of TiB2. The composites exhibited varying microstructures and mechanical properties with the increase in boride content. Load transfer strengthening was found to be the main contributor to the overall strength of the composite. The biocompatibility evaluation suggested a decrease in the proliferation rate of mesenchymal stem cells with an increase in boride content.

Summary: The optoelectronic properties of free-standing few-atomic-layer black phosphorus nanoflakes are analyzed using in situ transmission electron microscopy (TEM). The band gap of black phosphorus (BP) is directly related to its thickness and strain, and can be tuned accordingly. Photocurrent measurements under TEM reveal stable response to infrared light and changes in band gap with deformation. Experimental results are further supported by density functional theory (DFT) calculations. These findings provide guidance for engineering the band gap of BP through controlling the number of atomic layers and programmed deformations for future optoelectronic applications.

Summary: In this study, an in situ transmission electron microscopy (TEM) heating system was used to investigate the morphological changes of cubic Ag nanoparticles (NPs) and Ag-based core-shell structures induced by sublimation, as well as the influence of shell coverage on thermal stability. It was found that large Ag NPs (>50 nm) showed a three-stage sublimation-induced morphological change, while small Ag NPs (<30 nm) showed a uniform sublimation. The sublimation process of core-shell NPs started at stage II, and the thermal stability was enhanced by carbon shell passivation.

Summary: This study used electron-beam irradiation to observe surface structural transitions on thin Au (1 0 0) and (1 1 0) specimens at different current densities. It was found that at low current densities, nanometer polygonal holes were formed with atomically sharp facets on both surfaces, while at higher current densities, the holes became filled and some facet surfaces were roughened.

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: 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.
