Cu3SbSe3‐Alloying‐Induced High Thermoelectric Performance and Mechanical Robustness in Bi2Te3‐Based Thermoelectric Materials

Advanced Science, EarlyView.
Combining microstructural engineering with Cu3SbSe3 alloying significantly improves the performance of Bi2Te3‑based thermoelectric materials, yielding a high zT of ≈1.45 (average zT ≈1.3 over 303–503 K), excellent mechanical robustness (Vickers hardness of 96 Hv and compressive strength of 187 MPa), and an impressive conversion efficiency of ≈6.9% at a

Carboxyl‐Guided Ultrafine Zinc‐Acetate Templating Enables Closed‐Pore Engineering in Coal‐Derived Hard Carbon Anodes for High‐Performance Sodium‐Ion Batteries

Advanced Science, EarlyView.
In this study, ≈2 nm zinc acetate templates are uniformly anchored on the surface of NaOH‐etched bituminous coal via chelation between carboxyl groups and Zn2+. Subsequently, phenolic resin encapsulation is employed to construct a hard carbon material with abundant closed‐pore structures, achieving a reversible capacity of 370.9 mAh g−1 and an ICE of ...

Grow p‐type MoS2 on FeNC for CO2 Sensing in Complex Environments with Intelligent Recognition

Advanced Science, EarlyView.
In situ growth of p‐type MoS2 (p‐MoS2) on N‐ and Fe‐enriched carbon (FeNC) nanosheets allows for detection of carbon dioxide (CO2) fluctuation levels as low as 50 ppm at 25 °C. The induced S vacancies (Svacs) and the modulated electron distribution jointly improved sensing selectivity to CO2. Abstract A wealth of theoretical studies demonstrates p‐type

All Biomass‐Based Solar‐Driven Interfacial Evaporator for Efficient Seawater Desalination and Power Generation

Advanced Science, EarlyView.
A fully biomass‐derived hydrogel for solar interfacial evaporation is engineered through Fe3+‐coordinated assembly of cellulose nanofibril (CNF) and lignosulfonate (LS). This sustainable evaporator achieves a high evaporation rate of 1.91 kg m−2 h−1 under 1 sun irradiation and demonstrates efficient desalination.

Phyto‐Confined CeOx with Synergistic Lattice Distortion and Oxygen Vacancies Drives Efficient Urea Electrosynthesis

Advanced Science, EarlyView.
Lattice‐distorted CeOx nanoparticles with abundant oxygen vacancies, confined in porous carbon (d‐CeOx/PC), enable efficient electrocatalytic urea synthesis from CO2 and NO3−. Contracted Ce─O bonds (≈2.29 Å) stabilize OV, creating electron reservoirs for flexible multi‐electron transfer.

Manipulating Surface Chemistry on the Microarchitecture of Coal‐Based Hard Carbon for Improved Sodium Storage

Advanced Science, EarlyView.
This study utilizes surface chemistry engineering to enhance coal‐based carbon materials for sodium storage. By introducing oxygen‐containing functional groups (OFGs) via pre‐oxidation, the researchers found that carboxyl groups delay decarboxylation during pyrolysis, enabling extended intermolecular rearrangement up to 600 °C while suppressing soft ...

A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems

Advanced Science, EarlyView.
Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...
