Isotopic partitioning of gaseous nitrogen emissions of natural terrestrial ecosystems

Environmental Research Letters
We estimated the emissions of different forms of gaseous nitrogen (N) from natural terrestrial ecosystems using newly upscaled soil δ ^15 N maps, data-constrained gas partitioning models, and incorporating the previously missing N input flux from rock ...

Research on N-bearing micro-nanoparticles in the earth’s deep interior: new forms of existence and migration in the nitrogen cycle

Frontiers in Earth Science
Nitrogen (N) is vital for life and widely distributed in Earth’s crust, mantle, and core. Current knowledge is largely limited to surficial biological N cycling, with poorly constrained deep geological cycling and its carrier forms.

Support‐Controlled Reaction Pathways via Dynamic Sulfur‐Mediated Interfaces for Selective Urea Electrolysis

Advanced Functional Materials, EarlyView.
Sulfur‐doped graphitized carbon nanofibers act as adaptive catalyst–support platforms, enabling dynamic sulfur‐mediated reconstruction and strong metal–support interactions. This unique behavior enhances catalyst stability and controls reaction pathways, achieving highly selective urea oxidation (∼92% N2) coupled with efficient hydrogen evolution ...

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes

Advanced Functional Materials, EarlyView.
We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

Mechanisms of Microplastic Effects on Carbon and Nitrogen Cycling in Aquatic and Terrestrial Ecosystems

Toxics
An emerging environmental pollutant, microplastics have garnered global attention due to their widespread presence in soil and aquatic ecosystems. Early research primarily treated microplastics as single pollutants, focusing on their individual toxic ...

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies

Advanced Functional Materials, EarlyView.
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...
