Supercapacitive Carbon‐Coated δ‐MnO2 Nanosheets as a Solid‐Contact Material for Self‐Testing Potassium‐Ion Biosensors

Small, EarlyView.
A simple and energy‐efficient method was developed to synthesize carbon‐coated δ‐MnO2 nanosheets (δ‐MnO2@C). This multifunctional material serves as both a supercapacitor electrode and a solid‐contact for self‐testing K+‐ion biosensors. Compared to activated carbon, δ‐MnO2@C enhances Faradaic supercapacitive properties, improving the K+‐ion sensing ...

Ultra‐Uniform Lithium‐Ion Transport Enabled by Supramolecular Polymeric Networks as Artificial Solid Electrolyte Interphase Layers for Highly Stable Lithium‐Ion Battery Anodes

Small, EarlyView.
Incorporation of p‐phenylenediamine (pPD) into the polymer–pPD supramolecular artificial SEI reduces the activation energy for Li‐ion desolvation at the interface and promotes Li‐ion transport through the layer, thereby ensuring uniform delivery of Li‐ion into the SCN and stable cycling performance regardless of the inherently uneven thickness of the ...

Direct Synthesis of Exfoliated Carbon Nitride Mediated by Sodiated Cellulose Nanocrystals for Photocatalytic and Adsorbent Applications

Small, EarlyView.
Few atomic‐layer‐thick carbon nitride nanosheets (CNNS) were synthesized using an in situ exfoliation technique. The directly exfoliated CNNS exhibited a wider electronic bandgap along with a fourfold increase in specific surface area and tenfold increase in pore volume.

Toward Efficient and Reliable Chemical Upgrading Using Solid Oxide Electrochemical Reactors, Mechanisms, Challenges, and Design Principles

Small, EarlyView.
Solid oxide electrochemical reactors (SOERs) offer a compelling pathway for coupling renewable electricity with chemical manufacturing, but their real application is still limited by low efficiency and instability. This review systematically summarizes SOER reaction mechanisms, performance‐limiting factors, and recent progress toward high‐efficiency ...

Recycling of Mill Scale Into High‐Purity Iron Through Hydrogen‐Based Reduction

steel research international, EarlyView.
Mill scale, an iron oxide–rich steel by‐product, is difficult to recycle due to impurities. This study evaluates hydrogen‐based direct reduction and hydrogen plasma smelting reduction as low‐carbon recycling routes. Impurity segregation limits reduction kinetics. Direct reduction achieves 92% conversion in 180 min, while plasma reduction reaches 91% in
