Compositing Effect Leads to Extraordinary Performance in GeSe‐Based Thermoelectrics

open access: yesAdvanced Functional Materials, EarlyView.
Rhombohedral GeSe is rationally designed with (GeSe)0.9(AgBiTe2)0.1‐1.5 mol.% SnSe, achieving a peak ZT of 1.31 at 623 K. Forming a composite with SnSe establishes interfaces with strong phonon scattering and weak electron scattering. Multiscale defects lead to an ultra‐low lattice thermal conductivity (0.26 W m−1 K−1), approaching the amorphous limit.

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

open access: yesAdvanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Bacteria‐Derived Extracellular Vesicle as A “Trojan Horse” for Selective M1 Macrophage‐Targeting in A Multi‐Cellular Entanglement Environment

open access: yesAdvanced Functional Materials, EarlyView.
The temporary transition of macrophages from a pro‐inflammatory phenotype of macrophages (M1) to an anti‐inflammatory phenotype of macrophages (M2) is crucial for tissue repair and regeneration processes. Bacterial outer membrane vesicles (OMVs) are utilized as a “trojan horse” for specific M1 macrophage‐targeting and anti‐inflammatory drug delivery ...

High Thermoelectric Performance in Low‐Cost Cu8SiSxSe6‐x Argyrodite

open access: yesAdvanced Functional Materials, EarlyView.
This study discovers the great potential of Cu8SiSxSe6‐x argyrodites as new, low‐cost, Te‐free thermoelectric materials. The proposed defect scheme suppresses the phase transition, enhances the weighted mobility and optimizes the grain boundary contacts.

Na2S Presodiation Enables Long Cycling Anode‐Free Sodium Batteries via Rapid Spontaneous Reactions

open access: yesAdvanced Functional Materials, EarlyView.
Na2S with high sodium content is utilized as a sodium replenishment material for AFSBs. The spontaneous reaction between polysulfides and Na3−xV2(PO4)3, complete conversion from Na2S to sulfur is achieved under low voltage and catalyst‐free conditions. With the assistance of the additionally supplied sodium ions, the Na2S@NVP||Zn AFSBs retain 70.8% of ...
