Topological Defects in Carbon Matrix Are Efficiently Constructed by Joule Thermal Shock for Catalyzing the Growth of Carbon Nanotubes

open access: yesAdvanced Science, EarlyView.
The Joule thermal shock technique ensures the efficient construction of topological defects in the carbon matrix because the instantaneous cooling suppresses the graphitization rearrangement of the heteroatom removal sites. This topological defect carbon can activate carbon source molecules by electron transfer, and further grow into carbon nanotubes ...

3D‐Printed Aerogel Metamaterials with Multiple Heterogeneous Interfaces Enables Integrated Control of Microwave Field, Acoustic Field, and Thermal Field

open access: yesAdvanced Science, EarlyView.
The Direct‐Ink‐Writing (DIW) 3D‐printed aramid nanofibers (ANF)/carbon nanotubes (CNT)/liquid metal (LM) aerogel metamaterial demonstrates an effective and lightweight strategy to achieve polarization insensitive & ultra‐wideband microwave absorption from 2.65‐18 GHz, broadband noise reduction effect in the 2800‐6400 Hz and thermal suppression ...

Non‐Equilibrium Synthesis Methods to Create Metastable and High‐Entropy Nanomaterials

open access: yesAdvanced Science, EarlyView.
ABSTRACT Stabilizing multiple elements within a single phase enables the creation of advanced materials with exceptional properties arising from their complex composition. However, under equilibrium conditions, the Hume–Rothery rules impose strict limitations on solid‐state miscibility, restricting combinations of elements with mismatched crystal ...

Intrinsic Negative Magnetoresistance and Broadband Photoresponse in Magnetic van der Waals Crystal TaFeTe2

open access: yesAdvanced Science, EarlyView.
2D van der Waals (vdW) materials MM′Te2 with broken symmetry attract great interest for unique magnetic structures and optical‐phonon‐induced phase transitions. We report mechanically exfoliable TaFeTe2 single crystals, exhibiting spin‐glass behavior, intrinsic unsaturated negative magnetoresistance up to 9 T, self‐powered internal photocurrent, and ...
