Hierarchical Flexible Ceramic Nanofiber Membrane for Simultaneous Membrane Distillation and Photocatalytic Hydrogen Evolution

Advanced Materials, EarlyView.
A hierarchical flexible ceramic nanofiber membrane integrates a La‐stabilized ZrO2 scaffold with superhydrophobic UiO‐66‐NH2/CdS heterojunctions. The gas–liquid–solid interfacial architecture sustains vapor‐selective desalination, visible‐light charge separation, and rapid H2 extraction, enabling simultaneous freshwater production and photocatalytic ...

Rietveld refinement of the RNi4B compounds (R = Gd, Tb, Er)

, 2007
Based on Rietveld refinement of X-ray powder diffraction data collected from RNi4B samples (R = Gd, Tb, Er) annealed at 1070 K, a CeCo4B structure type (space group P6/mmm (N191), Z= 2) was determined for all ...

Multi‐Biomimetic Structural Colors Inspired by Pearls and Bird Feathers

Advanced Materials, EarlyView.
A dual‐biomimetic strategy mimicking pearls and bird feathers is proposed to construct full‐gamut structural colors. By integrating a non‐strictly periodic inorganic multilayer architecture with tunable light absorbers, this facile approach circumvents the complex fabrication of traditional 1D photonic crystals, offering immense potential for cosmetics,

A Family of Sodium Solid‐State Electrolytes Based on the NaGaxAl1‐xCl4 Solid Solution

Advanced Materials Interfaces, EarlyView.
ABSTRACT Sodium‐based metal chloride solid electrolytes are promising for sodium solid‐state batteries due to their excellent oxidation stability, which, as shown for Li halides, can coexist with high ionic conductivity. To explore cationic substitution effects, we synthesized NaGaxAl1‐xCl4 (0 ≤ x ≤ 1) via ball milling and investigated structural and ...

Mineralogical study of phosphate rocks by quantitative rietveld refinement

Open Ceramics
Phosphorites from the Kodjari deposits of Burkina Faso are composite rocks with a fine-grained matrix phase and dispersed larger grains. Chemical analysis by XRF revealed a CaO content of 35.98–41.33 wt% and a P2O5 content of 26.85–30.75 wt%.
