Summary: In this study, a designed intense stretching process was used to construct a highly oriented and condensed shish-kebab crystalline structure, which improved the mechanical properties and in-plane thermal conductivity of the HDPE/UHMWPE blends. By introducing disentangled UHMWPE chains and utilizing multistage stretching extrusion and uniaxial stretching, the tensile strength, Young's modulus, and in-plane thermal conductivity of the blends were significantly increased. This research provides a new perspective on the application of high-performance polyethylene blends.

Summary: The study reveals that the step density on high-index surfaces plays a crucial role in the epitaxial growth of 2D single crystals, while surface roughness and alignment of step edges are important factors affecting the orientation of hBN. High-index surfaces with large step density are robust for templating the epitaxial growth of 2D single crystals.

Summary: According to previous research, wastewater treatment plants can retain over 90% of microplastics found in wastewater, but a significant portion of the removed microplastics may be retained in the sludge, potentially causing environmental issues. This study found that microplastics have selective effects on the bacterial community in activated sludge, but do not impact the abundance of nitrifying and denitrifying bacteria in the sludge.

Summary: Through the physical vapor deposition strategy, controllable synthesis of horizontal tellurium nanoribbon arrays on mica substrates with an angular interval of 60 degrees is achieved. The growth of tellurium nanoribbons is driven by the quasi-one-dimensional spiral chain structure and the epitaxy relationship between tellurium and mica. The bending of the nanoribbons, induced by grain boundary, is a new phenomenon. Field-effect transistors based on tellurium nanoribbons demonstrate high mobility and on/off ratio.

Summary: The successful synthesis of a superconductor-ferromagnet heterostructure using molecular-beam epitaxy technique demonstrates that the monolayer of CrBr3 maintains its ferromagnetic ordering under external magnetic field, leading to a slight reduction in the superconducting gap of NbSe2 and the formation of a vortex lattice on the CrBr3 layer. These findings suggest the potential of leveraging proximity effects to achieve novel phenomena in 2D heterostructures.
