Association between maternal serum zinc and birth weight is modified by neonatal SOD2 polymorphism and promoter methylation.

Background: Conflicting findings exist regarding the association between maternal serum zinc and neonatal birth weight. This study aimed to explore the association between maternal serum zinc and birth weight, and whether this association was modified by neonatal SOD2 polymorphism and promoter methylation.

Methods: We recruited 464 mother-newborn pairs at Houzhai Center Hospital from January 2010 to January 2012.

Tuning the spin state of the iron center by FePc/Mg(OH) heterojunction boosting oxygen reduction performance.

Iron phthalocyanine (FePc) is a promising non-noble metal catalyst for oxygen reduction reaction (ORR). While, with the plane-symmetric FeN site, the ORR activity of FePc is generally low due to its low ability to adsorb and activate O. Herein, we anchor FePc on Mg(OH)/N-doped carbon nanosheets building the ternary plate-like catalyst FePc/Mg(OH)/NC.

Effects of leading-edge serration shape on noise reduction in rod-airfoil interactions.

Leading-edge serrations inspired by owls exhibit the capability to control airfoil-turbulence interaction noise, but the design principle of the serration shape is still an open issue. To this end, we designed five types of serration shapes with different combinations of curvature, namely, triangular, ogee, anti-ogee, feather-like, and anti-feather-like. These curves are applied to serrated modifications with different bluntness levels (sharp or blunt) and amplitudes (0.

Topologically Engineered High- Quasi-BIC Metasurfaces for Enhanced Near-Infrared Emission in PbS Quantum Dots.

Enhancing photoluminescence (PL) efficiency in colloidal quantum dots is pivotal for next-generation near-infrared photodetectors, imaging systems, and photonic devices. Conventional methods, especially metal-based plasmonic structures, suffer from large optical losses, which limits their practical use. Here, we introduce a quasi-bound state in the continuum (quasi-BIC) metasurface on a silicon-on-insulator platform, tailored to provide high-quality factor resonances with minimized losses.

Moisture-Electric Generators Working in Subzero Environments Based on Laser-Engraved Hygroscopic Hydrogel Arrays.

Moisture-electric generators (MEGs) generate power by adsorbing water from the air. However, their performance at low temperatures is hindered due to icing. In the present work, MEG arrays are developed by laser engraving techniques and a modulated low-temperature hydrogel as the absorbent material.
