Satellite Observations Reveal Complex Zonal Shifts of Western Boundary Currents Over the Past Three Decades

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Subtropical western boundary currents (WBCs) are major conduits of ocean heat and momentum, playing a fundamental role in Earth's climate. Satellite observations reveal complex zonal movements and a pronounced meridional asymmetry in WBC shifts, yet lack a unifying explanation. Here, using quasi‐geostrophic theory and numerical experiments, we

Oceanic Eddy Modulation of Wintertime Air‐Sea Coupling and Marine Atmospheric Boundary Layer Winds Over the East China Sea

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract This study examined the effects of air‐sea coupling and oceanic mesoscale eddies on wintertime low‐level wind events within the marine atmospheric boundary layer (MABL) over the Kuroshio front zone in the East China Sea. High‐resolution (eddy‐resolving, 5 km) and low‐resolution (50 km) simulations were conducted using prescribed sea surface ...

Properties data for opening the Galileo's partially unfurled main antenna [PDF]

open access: yes
An investigation was conducted into the friction and wear behavior of both unlubricated and dry-film-lubricated (Tiolube 460) titanium alloy (Ti-6Al-4V) in contact with an uncoated high-nickel-content superalloy (Inconel 718) both in vacuum and in air ...

The Micro‐Nano Hybrid Filler Al2O3 @CuNPs Is Used to Improve the Thermal Conductivity of Epoxy Resin Composites

open access: yesJournal of Polymer Science, Volume 64, Issue 6, Page 1518-1527, 15 March 2026.
Improved thermal conductivity of EP by mirco‐nano hybrid fillers. ABSTRACT In this study, a micro/nano hybrid filler comprised of Al2O3@CuNPs is synthesized through a chemical reduction method. The incorporation of Cu nanoparticles serves as a bridge, addressing the contact issues within the filler and substantially enhancing its ability to establish a

Resistance of nickel-chromium-aluminum alloys to cyclic oxidation at 1100 C and 1200 C [PDF]

open access: yes
Nickel-rich alloys in the Ni-Cr-Al system were evaluated for cyclic oxidation resistance in still air at 1,100 and 1,200 C. A first approximation oxidation attack parameter Ka was derived from specific weight change data involving both a scaling growth ...
