Stacked Nanosheet Gate‐All‐Around Morphotropic Phase Boundary Field‐Effect Transistors

open access: yesAdvanced Science, EarlyView.
This study proposes a material design using ferroelectric‐antiferroelectric mixed‐phase HZO to achieve steep subthreshold swing and non‐hysteretic on‐current enhancement in morphotropic phase boundary field‐effect transistors (MPB‐FETs). For the first time, two‐stacked nanosheet GAA MPB‐FETs with optimized HZO are demonstrated, validating superior ...

Massage‐Mimicking Nanosheets Mechanically Reorganize Inter‐organelle Contacts to Restore Mitochondrial Functions in Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
Parkinson's disease (PD) progression is aggravated by disrupted inter‐organelle contacts, which are influenced by mechanical forces. NanoMassage, 200 nm PEGylated black phosphorus nanosheets, deliver targeted mechanical stimulation to neural cells.

Serrated Leaf‐Like N‐Doped Copper Sulfide Enabling Bifunctional Oxygen Reduction/Evolution via Dual‐Mode Cathode Reactions for High Energy Density and Cycle Stability in Zinc–Air Batteries

open access: yesAdvanced Science, EarlyView.
A serrated leaf‐like nitrogen‐doped copper sulfide (N‐CuS) cathode with hybridized N 2p – S 3p orbitals is presented, mesopores for oxygen transport, and a five times larger electrochemical active surface area than Cu. In aerobic conditions, a zinc–air battery with N‐CuS achieves 788 mAh g⁻¹ and 916 Wh kg⁻¹, outperforming Pt/C+RuO₂.

Constructing Stable Bifunctional Electrocatalyst of Co─Co2Nb5O14 with Reversible Interface Reconstitution Ability for Sustainable Zn‐Air Batteries

open access: yesAdvanced Science, EarlyView.
A bifunctional electrocatalyst of Co─Co2Nb5O14 with a strong interaction interface is fabricated, and a bidirectional adsorption/migration mechanism of oxygen species between the reversible active sites of Nb5+/Nb4+ has been proposed. With the catalytic strategy design, the liquid Zn‐air batteries exhibits long‐term stability over 2050 cycles, and the ...
