Linking microstructure and local mechanical properties in SiC-SiC fiber composite using micromechanical testing
Published 2019“…The matrix has complex hierarchical microstructure with elongated grains, often featuring twinning, growing radially from the fibers in predominantly <111> direction and forming sets of concentric rings around them. The fibers contain equiaxed grains with carbon precipitates at the grain boundaries. …”

Narsarsukite Na2TiOSi4O10 as a low voltage silicate anode for rechargeable Li-ion and Na-ion batteries
Published 2020“…Fast lithium (de)insertion without any significant capacity loss can be linked to the rigid endless large tunnels built from the stacked rings of four SiO4 tetrahedra. This silicate material was further found to work as a 0.53 V anode for sodium-ion batteries delivering capacity close to 30 mAh·g-1 (at a rate of C/10). …”

Mechanics of fracture and flexure in Antarctic ice sheets and ice shelves
Published 2024“…In grounding zones and floating ice shelves, ice fracturing is often associated with flexure modulated by ocean tides and subglacial water flow, as well as stresses created by shearing, such as pinning points. Fracture and flexure significantly affect the vulnerability of Antarctic ice shelves to hydrofracturing and, by altering buttressing effects, the mass balance of the entire Antarctic Ice Sheet. …”

Laser-induced reduced-graphene-oxide micro-optics patterned by femtosecond laser direct writing
Published 2020“…The optical performances of Fresnel zone plates (FZP) fabricated under the three regimes were evaluated and compared; the results were 0.7%, 2.4%, and 3.8% for focusing efficiency, 12.2 µm, 13.2 µm, and 12 µm for focal spot size, 1.39 mm, 1.89 mm, and 1.77 mm for depth-of-focus for FZPs designed to 15 mm focal length with 10 concentric rings. This fabrication technique provides wide design flexibility to various planar LIRGO micro-optics for microfluidics, lab-on-a-chip, skin-attachable biomedical imaging, and micro photonic devices.…”

Acidic corrosion behaviour of niobium-added welding overlays fabricated by self-shielded metal-cored wires
Published 2024“…Both corrosion and abrasion remove materials from some engineering components such as impact coal crusher hammers, pulverizer rings, chute liner, and rolls or molds. Intensive research has been done on improving the wear resistance of high chromium alloys, however, studies into corrosion resistance of high chromium alloys are insufficient. …”
