A Cu2S/NiOOH Heterojunction Enables Highly Selective Ammonia‐to‐Nitrite Electrooxidation at Industrially Relevant Current Densities

Advanced Materials, EarlyView.
Cu2S/NiOOH heterojunction enables efficient ammonia electrooxidation coupled with hydrogen evolution. Interfacial electronic modulation of Ni sites promotes selective NH3‐to‐NO2− electrooxidation at high current density. In a membrane electrode assembly, Cu2S/NiOOH maintains over 90% Faradaic efficiency of nitrite at 800 mA cm−2, highlighting its ...

Thermal and crystallization behavior of lithium-modified Al

Open Ceramics
The effect of Li 2 O addition (0–10 wt.%) on the thermal properties and crystallization kinetics of Al 2 O 3 –CaO–K 2 O–Na 2 O–SiO 2 glasses is systematically investigated. Increasing Li 2 O content modifies the silicate network, resulting in an increase

Light‐Programmed Localized Supersaturation Enables Ambient Aqueous Synthesis of Highly Crystalline Metal–Organic Frameworks

Advanced Materials, EarlyView.
In the proposed model, a photoinduced nanoreactor uses Cu2O self‐photooxidation to generate localized supersaturation. A metastable supersaturation state first forms a shell, creating a spatially confined environment that restricts reactant exchange; continued Cu release then drives the local environment toward a labile regime that favors predominantly

Inverse Design of Nanoparticulate Materials

Advanced Materials, EarlyView.
Inverse design shifts nanomaterial development from empirical trial‐and‐error to predictive model‐driven strategies. It can rely on knowledge‐based, data‐based, or hybrid process and property functions. This perspective article provides a practical framework for applying inverse design based on instructive examples. It discusses which modeling approach

Percolation‐Driven β‐Relaxation Enables Resonant Acceleration of Crystallization in Amorphous Phase‐Change Materials

Advanced Materials, EarlyView.
Mobile‐atom percolation underlying β‐relaxations fundamentally dictates the crystallization pathways of phase‐change materials. High‐frequency ultrasonic excitation dynamically modulates this critical mobility percolation network, substantially accelerating the crystallization process.
