Textural and geochemical characteristics of late Pleistocene to Holocene fine-grained deep-sea sediment cores (GM6 and GM7), recovered from southwestern Gulf of Mexico

Journal of Palaeogeography, 2018
Texture, mineralogy, geochemistry, and 14C ages of two deep-sea sediment cores (GM6 and GM7) recovered in the southwestern Gulf of Mexico were investigated to infer their provenance and depositional condition.

Bridging Horizontal to Vertical Radiative Cooling

Advanced Science, EarlyView.
Radiative cooling materials are mature but only work facing the sky, confining them to rooftops. Instead of developing new ones, this system bridges existing horizontal coolers to vertical windows using blades outside the glass. On an occupied urban building, windows stay up to 1.4°C below air temperature while preserving daylight, outward views, and ...

Temperature‐Driven Silicate Weathering Feedbacks Terminated the Middle Eocene Climatic Optimum

Geophysical Research Letters
Continental hydroclimate dynamics and its responses during the Middle Eocene Climatic Optimum (MECO, ∼40 Ma) remain largely unexplored. Here, we present high‐resolution multi‐proxy records from four East Asian lake basins that demonstrate precipitation ...

Water‐Soluble POSS Promotes Concurrent Coalescence and Crosslinking for Multiscale‐Reinforced, Coalescent‐Free Waterborne Coatings

Advanced Science, EarlyView.
Water‐soluble amine‐functionalized polyhedral oligomeric silsesquioxane promotes concurrent latex coalescence and crosslinking, allowing epoxy‐functional particles to form continuous films without added volatile coalescing agents. The resulting multiscale‐reinforced waterborne coatings combine high strength, toughness, optical transparency, scratch ...

Polydopamine‐Wool Textiles for Sustainable Interfacial Solar Vapor Generation

Advanced Science, EarlyView.
A natural wool textile engineered for high solar absorbance and a fast‐wicking structure serves as a highly efficient, single‐layer system for interfacial solar vapor generation (ISVG). This integrated evaporator seamlessly couples rapid water transport with continuous evaporation. Ultimately, this sustainable photothermal design offers a scalable, eco‐

The Sediments in the Beibu Gulf Reveal Dramatic Paleoenvironmental Changes and Climate Events over the Past ~20,000 Years

Journal of Marine Science and Engineering
The geochemical characteristics of a 2.1 m BBW25 core, collected from the Beibu Gulf, have been investigated in terms of the major and trace elements, organic matter, and CaCO3 and AMS 14C dating by XRF, ICP-OES, ICP-MS, and more.

Low chemical weathering intensity, enhanced erosion, and euxinic conditions along the Norwegian margin during the paleocene-eocene thermal maximum [PDF]

The Paleocene–Eocene Thermal Maximum (PETM; ∼55.9 Ma) was a rapid global warming event marked by intensified hydrological cycling, enhanced continental weathering, and widespread ocean deoxygenation.

Strongly Anisotropic and Rapid Excitons Transport in Organic Crystal

Advanced Science, EarlyView.
The increased exciton diffusion length is beneficial to simplify device design and enhance photoelectric conversion efficiency. But the isotropic exciton diffusion may lead to reduced transport efficiency directed to the charge separation site. Here we have successfully achieved strongly anisotropic and rapid excitons transport in thienopyrrole ...

Modeling the evolution of natural cliffs subject to weathering. 2, Discrete element approach [PDF]

, 2011
The evolution of slopes subjected to weathering has been modeled by assuming Mohr-Coulomb behavior and by using a numerical approach based on the discrete element method (DEM).
