Summary: Silicon-based anodes with single-walled carbon nanotubes (SWCNTs) network exhibit higher initial discharge capacity, higher initial Coulombic efficiency, exceptional cyclic stability, and higher lithium-ion diffusion coefficient compared to those with multiwalled carbon nanotubes (MWCNTs) network. The underlying mechanism behind this difference is elucidated through in situ Raman spectroscopy and theoretical analysis. It is determined that the more flexible SWCNTs and their stronger van der Waals forces enable better contact between SiOx@C and SWCNTs under large stress during cycling.

Summary: The scaffold plays a crucial role in tissue engineering, especially in addressing large defects or replacements of pathological tissues or organs. The interaction between cells and scaffold, as well as the integration with the surrounding biological tissue, is key to the expected outcome. Mimicking the natural extracellular matrix (ECM) of the tissue being healed can further optimize the healing process and minimize morphological mismatch. Using 3D printing technology, bioinspired scaffolds with microstructures resembling trabecular architecture were fabricated for bone tissue engineering. These scaffolds showed excellent adhesion, growth, and differentiation of osteoblast-like cells, indicating their potential in bone tissue engineering and regenerative medicine applications.

Summary: One-dimensional moire stripes are discovered and investigated on the surface of three-dimensional topological insulator thin films and nanobelts. The local density of states in the stripes is found to be strongly enhanced compared to the bulk system.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.
