Cobalt‐Free Single‐Crystal Cathodes for Next‐Generation Lithium‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Cobalt‐free single‐crystal cathodes enhance lithium‐ion battery stability by mitigating fracture, degradation, and phase transitions. This review highlights Ni‐rich layered, Li‐Mn‐rich, spinel, and olivine frameworks, synthesis strategies enabling morphology and defect control, and structural tuning via doping and coatings, offering pathways toward ...

Rock Art

open access: yes, 2009
Rock art, basically being non-utilitarian, non-textual anthropic markings on natural rock surfaces, was an extremely widespread graphical practice in ancient Egypt. While the apogee of the tradition was definitely the Predynastic Period (mainly fourth millennium BCE), examples date from the late Palaeolithic (c.

Nanocubes and Cuboctahedra: Entropic Stabilization Versus Thermal Segregation in Rock Salt‐ and Spinel‐Type Multinary Oxides from Spray‐Flame Synthesis

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Spray‐flame synthesis enables highly flexible and scalable production of multinary and high‐entropy oxide nanoparticles due to high synthesis temperatures with subsequent quenching. Temperature‐dependent in situ diffraction of as‐synthesized materials clearly reveals entropy stabilization in rock salt lattices, while spinels—featuring tetrahedral and ...

Letting People in: Redefining Collaboration in Wildland–Urban Interface Governance

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Intensifying wildfire regimes and expanding human settlements into wilderness areas have heightened concerns about the wildland–urban interface (WUI) due to the associated increase in fire risk. However, the WUI presents broader social‐ecological challenges that go beyond wildfire risk and remain understudied.

Seismic Performance and Vibration‐Based Damage Identification of Two‐Storey Balloon‐Framed CLT Shear Walls

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT While cross‐laminated timber (CLT) is increasingly utilized in lateral force‐resisting systems in mass timber construction, research has predominantly focused on platform‐type construction. Balloon‐type CLT shear wall systems offer distinct structural advantages, notably the elimination of cumulative perpendicular‐to‐grain compression and a ...
