2D Co‐Assembly of Solid Acids Enables Stable Superprotonic Conduction Above 260°C

open access: yesAdvanced Functional Materials, EarlyView.
A two‐dimensional co‐assembly strategy integrates antimony phosphate and phosphotungstic acid nanosheets into free‐standing inorganic lamellar membranes with confined acid–acid interfaces. The resulting interfacial hydrogen‐bond network enables anhydrous proton conductivity exceeding 0.1 S cm−1 at 260°C and supports stable high‐temperature fuel‐cell ...

Balancing Hydrophobicity and Hydrophilicity: Dual Filler‐Engineered Proton Exchange Membranes for Durable, High‐Power Fuel Cells

open access: yesAdvanced Functional Materials, EarlyView.
Polarity‐matched Zr–MOFs program Nafion's nanoscale morphology during solution casting. Hydrophilic UiO‐66 preserves hydrated pathways, while hydrophobic UiO‐67 increases the proton hopping sites by densifying ionic clusters. Combining both fillers yields a membrane that delivers 176 mS cm−1 conductivity, reaches 1.46 W cm−2 under 200 kPa, and triples ...

Confinement‐Engineered Thermally Programmed Ion‐Gating Separator for Decoupling Thermal–Electrochemical Feedback in High‐Energy Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A new phase‐change material encapsulated membrane offers more thermal resilience stability and safety than the conventional separators for batteries. ABSTRACT Thermal runaway in lithium‐ion batteries arises from the intrinsic coupling between heat generation and ion transport, yet conventional shutdown separators primarily rely on passive pore collapse

Chitin‐Derived Carbon‐Metal Functional Materials

open access: yesAdvanced Functional Materials, EarlyView.
Functional carbon materials are synthesized from combination of biopolymer (chitin) and iron precursors. The resultant material exhibits superior surface area and adsorptive properties compared to carbon materials synthesized directly from pure chitin.

Fullerene‐Mediated Iodine Immobilization at Buried Interfaces in Sn–Pb Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
Indene‐C60 bisadduct (ICBA) accumulates at the buried interface of inverted tin‐lead perovskite solar cells, limiting undesired electron extraction while maintaining efficient hole transport. ICBA simultaneously scavenges molecular iodine, mitigating Sn2+ oxidation and interfacial recombination. This coupled electronic‐chemical regulation delivers 22.7%

Effects of coastal wetland reclamation on soil organic carbon, total nitrogen, and total phosphorus in China: A meta‐analysis

Land Degradation & Development, 2023
The reclamation of coastal wetlands for agriculture has expanded considerably over the last 40 years in China. Wetland reclamation could substantially alter soil properties, but so far, a systematic analysis of the changes in soil chemical elements after

Simultaneous partial nitrification, Anammox and nitrate-dependent Fe(II) oxidation (NDFO) for total nitrogen removal under limited dissolved oxygen and completely autotrophic conditions.

Science of the Total Environment, 2023
Sustainable nitrogen removal from wastewater at reduced energy and/or chemical consumptions is challenging. This paper investigated, for the first time, the feasibility of coupled partial nitrification, Anammox and nitrate-dependent Fe(II) oxidation ...

Influence of soil properties, topography, and land cover on soil organic carbon and total nitrogen concentration: A case study in Qinghai-Tibet plateau based on random forest regression and structural equation modeling.

Science of the Total Environment, 2022
The effects of topography, land cover type, and soil physicochemical properties on the distribution of soil organic carbon (SOC) and total nitrogen (TN) have drawn growing attention recently, but little is known about how these features-associated ...

Impacts of the components of conservation agriculture on soil organic carbon and total nitrogen storage: A global meta-analysis.

Science of the Total Environment, 2022
Conservation agriculture (CA) can be an important strategy for improving soil organic carbon (SOC) and total nitrogen (TN). Numerous studies have examined SOC and TN dynamics in different cropping systems. However, there is some uncertainty regarding the
