Mechanical Performance Retention of CNT‐Modified Sisal Biocomposites Under Hygrothermal‐Saline Aging

open access: yesPolymer Composites, EarlyView.
Mechanical Performance Retention of CNT‐Modified Sisal Biocomposites Under Hygrothermal‐Saline Aging. ABSTRACT This study investigates the influence of carbon nanotubes (CNTs) on the moisture absorption kinetics and mechanical degradation of discontinuous random fiber (DRF) biocomposites under accelerated hygrothermal–saline (HTS) aging.

Fiber‐Reinforced Bio‐Epoxy Composites: Degradation Mechanisms in Saline Environment

open access: yesPolymer Composites, EarlyView.
Constituent level degradation of bio‐epoxy composites after saline aging. ABSTRACT This study examines the degradation behavior of bio‐epoxy composites reinforced with glass, basalt, carbon, and flax fiber yarns in a simulated saline environment. Fiber yarns and composite samples were exposed to 3.5% NaCl solution at 60°C for up to 3000 h.

The Effect of the Aging Process of Polyamide 11 Used in Flexible Pipelines and Its Influence on the Permeability of Carbon Dioxide

open access: yesPolymer Engineering &Science, EarlyView.
Field degradation inducing changes in the Polyamide 11 permeability. ABSTRACT This study investigates how long‐term natural aging affects the CO2 permeability of polyamide 11 (PA11) pressure sheaths recovered from decommissioned flexible risers. PA11 samples were extracted from two 18‐year‐old risers—a gas‐lift line and an oil‐production line—and ...

Scale dependence of the marine atmospheric boundary‐layer response to ocean surface‐temperature variability in the EUREC4$$ {\mathrm{EUREC}}^4 $$A region

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
With a minimal physics model and a high‐resolution fully 3D simulation, we demonstrate that the marine atmospheric boundary layer (MABL) response to sea‐surface temperature (SST) variability displays a dependence on the horizontal scales of motion.

Evolution of sea fog based on meteorological and oceanographic observations during FATIMA Yellow Sea campaign

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study presents a conceptual framework linking sea‐water temperature Tw gradients to the formation and persistence of sea fog in the southeastern Yellow Sea. Over cold waters maintained by tidal mixing, downward latent heat flux enhances lower‐level stability and sustains persistent sea fog, whereas over warmer waters, upward fluxes and thermal ...
