Multi-process regulation of surface residual stress for improving SCC resistance of Al-Zn-Mg-Cu alloy high-lock nuts

Aerospace high-lock nuts, as core aircraft fasteners, face severe stress corrosion cracking (SCC) risks during long-term service, threatening flight safety. This study investigates the effects of closing, stress relief aging and shot peening on residual stress, SCC resistance and...

Effects of a Waterborne Coating on the Moisture Response, Surface-Layer Structure, and Mechanical Properties of Inorganic-Bonded Bamboo Composite

Inorganic-bonded bamboo composite (InorgBam) combines the lightweight, high-strength nature of bamboo bundles with the heat resistance, low smoke emission, and environmental compatibility of inorganic binders. However, the inherent surface pores and inter-bundle gaps in this mate...

Complete genome-derived metabolic interactions reveal the impact of gut ecology on human health

Abstract Metabolic interactions govern gut microbiome assembly, yet functional rules remain obscured by genomic incompleteness and fragmentation. Here, we leverage 1,150 complete genomes to construct genome-scale metabolic models, demonstrating that draft genomes introduce system...

Deformation behavior of plastic-metal hybrid components for optical image stabilization: from injection molding to thermal processing

Abstract Micro-structured plastic-metal hybrid (MPMH) components fabricated by insert injection molding are widely used in miniaturized optical modules because of their structural integration and multifunctional performance. However, the multi-stage processes from injection moldi...
