Abnormal intensity and polarization of Raman scattered light are found at edges of layered MoS2. The Raman intensity can be enhanced obviously when the polarization direction of incident light is parallel to the edges. Forbidden Raman modes are observed at edge regions, and the polarization of Raman scattered light can be modulated by the edge structure. These abnormal phenomena are attributed to the modulation of the electric fields for the incident and Raman scattered light at edges.

Here the in-plane thermal conductivity of few-layer Ta2NiS5 is investigated through Raman thermometry. The measured Raman modes and thermal conductivities show strong anisotropy and obvious thickness-dependence for few-layer Ta2NiS5 flakes, which probably come from longer phonon mean free path and weaker phonon boundary scattering in armchair direction. Such anisotropic property might enable heat flow manipulation in Ta2NiS5 based devices to improve thermal management and device performance.

Nanocrystalline Au (n-Au) materials are prepared via high-pressure cold-forging of metastable 4H Au nanoribbons (NRBs). The combination of high-pressure cold-forging and in-situ 4H-to-face-centered cubic (fcc) phase transformation can effectively inhibit the grain growth in the obtained n-Au, leading to the formation of novel hard n-Au materials. Our strategy opens up a new avenue for the preparation of nanocrystalline metals with superior mechanical property.

Wuhan University of Technology, China
Three types of chiral structures differed in the scale (including molecular-scale, sub-nanoscale, and nanoscale) were constructed to reveal the chiral effect on amyloid-beta (Aβ) fibrillation exerted by structures in different scales. The molecular-scale and sub-nanoscale chiral structures could accelerate the fibrillation with chirality discrimination and induce the agglomeration of Aβ40, respectively. Only the nanoscale chiral ZnS quantum dots (QDs) could inhibit Aβ fibrillation with chirality discrimination. This work provides new insights in further understanding the mechanism of biological disorders including Alzheimer’s disease.
