Unexpected Oil Cyst Formation Following Lower Blepharoplasty Despite Adinizer-Assisted Microfat Grafting: Limitations of Fat Particle Size Reduction

Oil cyst formation after periocular autologous fat grafting is infrequently reported but represents a clinically relevant complication because it may present as a palpable mass and mimic other eyelid lesions. Various fat-processing techniques, including mechanical microfragmentat...

Effect of spray temperature on microstructure and corrosion resistance of cold-sprayed zinc coatings

Pure zinc (Zn) coatings were prepared on gray cast iron surfaces by cold spray (CS) to improve their corrosion resistance. The effects of spray temperature on deposition behavior, microstructural characteristics and corrosion performance of Zn coatings were investigated. Higher g...

MOF-derived amorphous Fe-ZIF-67/Nitrogen-Doped porous carbon for safe and efficient decomposition of energetic materials

Efficient and safe combustion catalysts are crucial for lowering the decomposition temperature and regulating the decomposition behavior of energetic materials (EMs), thereby improving propellant performance. Here, using a salt‑template strategy to prepare nitrogen‑doped porous c...

MBAvol: An Interpretable Descriptor Scheme for Crystal-Density Modeling of HEDM

Abstract Machine learning (ML) offers an efficient route to predict properties of high-energy-density materials (HEDMs), but conventional models often have limited interpretability and out-of-sample accuracy. Here, we introduce the multibody approximation volume descriptor (MBAvo...

Residual strength and failure-mode transitions of loess–steel interface under large-displacement ring shear

Shear behaviour at the loess–steel interface governs load transfer in steel pile foundations and retaining structures in collapsible loess regions. However, the large-displacement behaviour of compacted loess–steel interfaces, particularly the evolution of residual strength and f...

Transient CFD-GuidedFast-Cycle ALD: Effects of ReactorConfiguration and Process Window

Abstract Atomic layer deposition (ALD) is a powerful vapor-phase thin-film technique that relies on sequential, self-limiting surface reactions to achieve atomic-scale thickness control and excellent conformality on three-dimensional substrates. In practical reactors, however, th...

Beyond Traditional Phenolics: Disulfide Bonds for Performance Enhancement of Aerospace Ablation‐Resistant Materials from Processing to Recycling

As a key material of solid rocket motor nozzles, phenolic resins (PR) possessing high char yield, good processability, and efficient repairable performance are strongly desired for advanced ablation materials. Achieving these requirements simultaneously is challenging for traditi...
