Disentangling Bulk and Surface Contributions to Charge and Discharge Fading in High‐Voltage LiCoO2

Advanced Functional Materials, EarlyView.
High‐voltage operation of LiCoO2 accelerates capacity fading through bulk and surface degradation. By introducing a LiTaO3 coating to selectively suppress surface degradation, bulk and surface contributions to charge and discharge fading are decoupled.

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite

Advanced Functional Materials, EarlyView.
The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

Quality assessment of ICESat-2 ATL03 denoising data based on spatial distribution and photon weight [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
The Ice, Cloud, and land Elevation satellite-2 (ICESat-2) adopts an advanced single photon detection system, which is susceptible to the influence of solar background noise. There are currently multiple methods for denoising ICESat-2 photon data, but due

Embedded Direct Ink Writing of Thermoset and Elastomeric Polymers via Frontal Polymerization

Advanced Functional Materials, EarlyView.
Embedded frontal polymerization direct ink writing (FP‐DIW) combines frontal ring‐opening metathesis polymerization with embedded 3D printing to decouple deposition from curing. A yield‐stress support bath stabilizes low‐viscosity inks, while on‐demand thermal initiation enables controlled front propagation. This approach expands the accessible feature
