Bedrock erosion by root fracture and tree throw: A coupled biogeomorphic model to explore the humped soil production function and the persistence of hillslope soils [PDF]
, 2010 In 1877, G. K. Gilbert reasoned that bedrock erosion is maximized under an intermediate soil thickness and declines as soils become thinner or thicker. Subsequent analyses of this "humped" functional relationship proposed that thin soils are unstable and

Advanced Science, EarlyView.Polymer‐based hydrogels have emerged as promising materials for atmospheric water harvesting (AWH) due to their high water affinity, tunable network structure, and excellent moisture adsorption‐desorption performance. Functional hydrogel systems enable efficient water capture and controlled release under low‐energy conditions, offering a sustainable ...

A normalised seawater strontium isotope curve: possible implications for Neoproterozoic-Cambrian weathering rates and the further oxygenation of the Earth [PDF]
, 2007 The strontium isotope composition of seawater is strongly influenced on geological time scales by changes in the rates of continental weathering relative to ocean crust alteration.

Effect of Artificial Weathering on the Properties of Industrial-Scale Thermally Modified Wood
BioResources, 2015 Thermally modified wood is widely used in cladding, decking, and other construction projects that are meant for outdoor exposure. The purpose of this study was to investigate changes in the color, microstructure, and chemical composition of heat-treated,

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 ...

REE fractionation during granite weathering and removal by waters and suspended loads: Sr and Nd isotopic evidence [PDF]
, 2001 Very few studies deal with REE (rare earth element) mobility within the system soil–soil solution–streamwater. In this article, we try to characterize the fractionation and the migration of the REE in a granite-derived soil system located in a small ...

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 ...
