Facile solvothermal synthesis of gear-shaped submicrostructured Y2O3:Eu3+ phosphor

, 2011
Y2O3:Eu3+ phosphors with 3-dimensional assembled gear-shaped submicrostructure were successfully synthesized through a controlled solvothermal approach followed by a subsequent heat treatment, without using any catalyst or template.

Organic–Inorganic Composite Nanofibers Based on YSZ Nanofibers Anchored PANI/SnS2 Heterojunction for Flexible Room Temperature NO2 Sensor

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel organic–inorganic YSZ@PANI/SnS2 composite nanofiber film was prepared via an in‐situ construction strategy of a PANI interfacial layer. The biomimetic "branch‐leaf" structure effectively disperses and releases stress and energy, while accelerating gas diffusion/transport and providing abundant active sites.

Support‐Driven Hydrogen Migration Enhances Ammonia Decomposition in Direct Ammonia Protonic Ceramic Fuel Cells

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Enhanced hydrogen species migration enabled by FN/BZY catalyst mitigates intermediate accumulation and improves DA‐PCFC performance during ammonia decomposition. Ammonia, with its high hydrogen density and carbon‐free nature, serves as ideal fuel for direct ammonia protonic ceramic fuel cells (DA‐PCFCs).
