Nanotech

Novel three-dimensional (3D) hierarchical nanoarchitectures of e-MnO2have been synthesized by a simple chemical route without the addition of any surfactants or organic templates. The self-organized crystals consist of a major e-MnO 2 dipyramidal single crystal axis and six secondary branches, which are arrays of single-crystal e-MnO 2 nanobelts.

Tuning electron correlation in magic

2021/3/19Tuning the interactions Elucidating the nature of the superconducting state in magic-angle twisted bilayer graphene (MATBG) has proven tricky. To study the role of electron-electron correlations in this state, Liu et al. placed another graphene bilayer, this one having a conventional arrangement of the graphene sheets, in the immediate vicinity of a sample of MATBG.

Tuning dual three

Graphite anode materials are widely used in commercial lithium-ion batteries; however, the long electron/ion transportation path restricted its high energy storage. In this experiment, we designed a copper/graphite composite with a dual three-dimensional (3D) continuous porous structure combining used nonsolvent-induced phase separation and heat treatment, in which a large amount of graphite
