Synergistic Mechano‐Fluidic Self‐Fusion of Poly(Vinyl Alcohol)‐Modified Liquid‐Metal Particles for Post‐Treatment‐Free Soft Electronics

open access: yesAdvanced Science, EarlyView.
Poly(vinyl alcohol)‐modified liquid‐metal particles form conductive networks through spray‐induced self‐fusion without additional post‐treatment. Spray impact initiates oxide‐shell rupture and electrical contact, while subsequent Marangoni flow and capillary forces promote particle redistribution, neck growth, and network consolidation. This sequential

"Spark plasma sintering" (SPS) de nanocompósitos de Al2O3-ZrO2 Spark plasma sintering (SPS) of Al2O3-ZrO2 nanocomposites

open access: yesCerâmica, 2007
Uma alternativa mais recente para a sinterização de cerâmicas nanocristalinas é a sinterização por plasma (Spark Plasma Sintering - SPS). Esse processo permite a utilização de temperaturas mais baixas e tempos muito menores, comparado com a sinterização ...

Oxygen Partial Pressure as a Kinetic Descriptor for Single‐Crystal Morphology in Mid‐Nickel Layered Cathodes

open access: yesAdvanced Science, EarlyView.
Scalable synthesis of single‐crystal mid‐nickel cathodes demands precise kinetic control over competing densification and grain growth. Oxygen partial pressure emerges as a quantitative descriptor of effective grain‐boundary mobility, acting through changes in the apparent sintering activation barrier.

Tungsten Matrix Composite Reinforced with CoCrFeMnNi High-Entropy Alloy: Impact of Processing Routes on Microstructure and Mechanical Properties

open access: yesMetals, 2019
Tungsten heavy alloy composite was developed by using novel CoCrFeMnNi high-entropy alloy as the binder/reinforcement phase. Elemental tungsten (W) powder and mechanically alloyed CoCrFeMnNi high-entropy alloy were mixed gently in high energy ball mill ...

Excellent Thermoelectric Performance Realized in SnSe Materials via Chemical Bond Tailoring Using GeTe as Molecule Scissors

open access: yesAdvanced Science, EarlyView.
The GeTe acting as “molecule scissors” can tailor chemical bond, the breaking of Ag‐Se bonds and the formation of Ge‐Se bonds occur in the A‐SnSe matrix, along with the formation of Ag2Se precipitates. This process helps to optimize the thermoelectric properties, and also improves its mechanical properties to a certain extent.

Engineering Spatially Localized Bioactive Microenvironments in Assembly Implants for Spatially Extended Bone Ingrowth

open access: yesAdvanced Science, EarlyView.
An assembly porous titanium/β‐TCP implant is developed to establish a spatially programmable osteogenic microenvironment for enhanced osseointegration. By decoupling mechanical support from bioactive ion release, localized ionic gradients generated from the β‐TCP module direct osteogenic activity and bone ingrowth toward the porous titanium framework ...

Targeted Perturbation of Mitochondrial Energy Metabolism via Thermoelectric Nanoflowers for Enhanced Cuproptosis Echoed With Immunotherapy

open access: yesAdvanced Science, EarlyView.
We fabricated a thermoelectric nanomedicine to disrupt the ATP energy supply for the copper transporter ATP7B, thereby enhancing cuproptosis and achieving synergistic immunotherapy for anti‐tumor purposes. The fabricated TBCT NFs can efficiently disrupt the electron transport chain function via superoxide‐induced NADH oxidation, leading to ATP ...
