Boron‐oxide‐assisted particle engineering stabilizes O3‐type layered cathodes for sodium‐ion batteries by mitigating phase transitions and lattice strain. Acting as flux and structural modifier, boron forms submicron hexagonal platelets with (003) facets and expanded Na‐layer spacing, enabling rapid Na⁺ diffusion and mechanical resilience.

A Quantitative Lithium Inventory Framework for Anode‐Free Lithium Metal Batteries
A component‐resolved lithium inventory framework quantitatively tracks Li redistribution across the cell in anode‐free NMC622||Cu pouch cells throughout cycling. Three sequential degradation stages are identified: formation‐driven cathode Li depletion, midlife inactive Li0 accumulation, and late‐stage runaway SEI thickening. The cathode, as the sole Li

Contact-induced mistuning at the blade–disk interface is a major source of variability in the dynamic response of bladed disks, yet its identification remains challenging due to the intrinsic complexity of the contact phenomenon.

Operando SECM decouples hydrogen evolution from other degradation pathways in Zn metal batteries by quantifying its contribution during Zn electrodeposition. Although HER is shown to account for only a minor fraction of the irreversible charge loss, it remains a key indicator of interfacial evolution and by‐product formation governing cycling ...

This work introduces a CeHP‐enabled multifunctional matrix‐activated electrode (MME) for high‐temperature PEM fuel cells, forming an electrochemically and mechanically functional matrix within the catalyst layer. The design increases peak power density by 38% and reduces voltage decay by 62% at 240 °C, while using only 40% of the Pt loading of a ...

A positively polarized ferroelectric β‐pvdf layer incorporating fluorinated boron nitride nanosheets (PPFBN) establishes a strong internal field that promotes Li+ transport toward the anode while suppressing the migration of polysulfide anions. In addition, its intrinsically low polysulfide affinity helps preserve protective‐layer functionality ...

Probabilistic Rotor Life Assessment Using Reduced Order Models
Probabilistic failure assessments for integrally bladed disks are system reliability problems where a failure in at least one blade constitutes a rotor system failure.

A Bioinspired Underwater Soft Robot for Active Intravesical Liquid Delivery and Mixing
A bioinspired underwater soft robot is reported that integrates an elastic strain energy‐driven soft robotic pump with a programmable flexible magnetic valve, enabling remotely controlled, programmable, and sustained liquid release and mixing. This functionality is enabled by the synergistic integration of elastic strain energy‐driven pumping and ...

Abstract 3D scanning is rapidly becoming a key maintenance tool. Aerospace was a pioneer in adopting 3D scanning technology because aircraft manufacture and maintenance require precision. Monitoring deterioration, removing components for maintenance, and verifying covert operations are not practical or helpful without technology.
