Ammonium Salts as Curing Agents to Obtain Ionic Epoxy Resins With a Thermoplastic‐to‐Thermoset Transition

Advanced Materials, EarlyView.
Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.

Toward Energy Efficient Electrochemical Valorization of Waste Nitrate and Sulfide

Advanced Materials, EarlyView.
This work introduces an integrated electrochemical strategy couples nitrate reduction with sulfide oxidation for energy‐efficient wastewater valorization. A Cu‐Co dual‑site catalyst, engineered for close proximity, promotes *NO2 relay and subsequently NH3 formation, enabling the system to operate at substantially reduced cell voltages and produce high ...

An Integrated Stainless Steel‐Based Electrode for Durable Direct Natural Seawater Electrolysis

Advanced Materials, EarlyView.
We report an integrated stainless steel‐based electrode featuring Pt atomic clusters anchored on a NiFe‐LDH anticorrosive layer. By regulating interfacial water dynamics to suppress chloride attack, this hierarchical architecture achieves superior durability (over 1000 h) and energy efficiency in direct seawater electrolysis, offering a cost‐effective ...

Nonaging low-carbon transformer steel

Metal Science and Heat Treatment of Metals, 1962
Low carbon transformer steel with a heightened (0.3 to 0.5%) content of silicon and a low carbon (under 0.03%) and sulfur (under 0.025%) content is recommended for a largescale application in the electric engineering industry as a nonaging soft magnetic material with a coercive force under 0.8 oersted.

Low-carbon manganese carburizing steels

Metal Science and Heat Treatment, 1985
High-manganese low-carbon steels may be a new and promising class of carburizing steels. They do not contain expensive elements or those in short supply, are simple in production, and possess high strength properties and sufficient plasticity of the core.
