Herein, we evaluate their performance in the acidic urinary environment characteristic of renal tubular acidosis (RTA). To this end, the corrosion response, degradation performance, and mechanical properties of Mg-xZn alloys with different zinc contents were examined in artificial urine (pH 5.7) designed to mimic RTA conditions. Relative to pure Mg, the Mg-6Zn alloy demonstrated a 2.35 times higher hardness and a 2.58 times higher ultimate tensile strength (UTS), reflecting substantial mechanical reinforcement. Initial immersion tests indicated that corrosion severity first decreased and then increased with higher Zn content. After 30 days, although the overall degradation of Mg-Zn alloys was greater than that of pure Mg, a reduced susceptibility to pitting corrosion was observed. Furthermore, the alloys maintained a UTS above 148.9 MPa and an elongation of 3.17 %, confirming preservation of essential mechanical integrity during degradation. These results highlight the potential of Mg-Zn alloys as functional biodegradable materials and provide insights for the design of next-generation magnesium-based bioresorbable implants.</div></div>","PeriodicalId":20742,"journal":{"name":"Progress in Natural Science: Materials International","volume":"36 2","pages":"Pages 382-392"},"PeriodicalIF":7.1,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147754120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that RF-sputtered TTO achieves exceptional conductivity (2.50 × 10² S/cm), seven orders higher than that of DC-sputtered films (1.60 × 10⁻⁵ S/cm), while maintaining outstanding optical transparency (&gt;85%).

Fe(Se, Te) materials, characterized by their simple crystal structure and low anisotropy, are promising candidates. However, fabricating high-performance Fe(Se, Te) wires via the powder-in-tube (PIT) method remains challenging due to the volatilization of Se/Te and the formation of non-superconducting phases during conventional heat treatments, which degrade grain connectivity and core density. This study introduces and validates a Rapid Heating and Quenching Treatment (RHQT) process as an innovative heat treatment for in-situ Fe(Se, Te) wires. Comparative analyses with traditional melting and solid-state sintering (SSS) methods demonstrate that the RHQT process effectively suppresses elemental volatilization, yielding a dense, chemically homogeneous, and primarily tetragonal β-Fe(Se, Te) phase filament with enhanced grain boundary connectivity. Consequently, the RHQT-processed wire exhibits superior superconducting properties: the highest transition temperature (<em>T</em>_c) of 14.5 K, the sharpest transition width (Δ<em>T</em>_c = 3.9 K), and significantly enhanced critical current density. The magnetic <em>J</em>_c at 5 K and self-field reached ∼4.0 × 10⁴ A/cm², while the transport <em>J</em>_c at 4.2 K achieved a high-performance of 6226 A/cm² for single-core Fe(Se, Te) wires. Moreover, the RHQT wire demonstrated exceptional in-field performance, with a much slower <em>J</em>_c decay, attributed to strong vortex pinning at the well-connected grain boundaries.

While quantitative microstructural characterization and microhardness measurements confirm a reduction in γ′ phase strengthening in the airfoil, the tensile properties remain comparable to those of the blade root. Fracture morphology analysis indicates that the η phase formed via MC carbide decomposition helps to alleviate local stress concentration.

Electrospun piezoelectric nanocomposites address these limitations by combining flexible polymer matrices with nanoscale structure, enabling efficient electromechanical energy conversion under low-frequency mechanical stimuli associated with human motion and physiological activities. This review critically examines recent progress in electrospun piezoelectric nanocomposites, emphasizing material design, fabrication, and applications.
