Polydopamine‐Wool Textiles for Sustainable Interfacial Solar Vapor Generation

open access: yesAdvanced 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‐

Weather Index Insurance for Agriculture

open access: yes, 2011
This paper is a distillation of the findings of the work undertaken by the World Bank. It is deliberately not a collation of case studies, but rather a practical overview of the subject. The purpose of this paper is to introduce task managers and development professionals, who are not insurance sector specialists, to weather index insurance. Ultimately,

Modelling weathering processes at the catchment scale: The WITCH numerical model [PDF]

open access: yes, 2006
A numerical model of chemical weathering in soil horizons and underlying bedrock (WITCH) has been coupled to a numerical model of water and carbon cycles in forest ecosystems (ASPECTS) to simulate the concentration of major species within the soil ...

Strongly Anisotropic and Rapid Excitons Transport in Organic Crystal

open access: yesAdvanced 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 ...

Weathering Influence on Properties of Siltstones from Istria, Croatia

open access: yesAdvances in Materials Science and Engineering, 2016
Slaking and weathering of weak rocks result in slope instability. Siltstones from flysch rock masses are highly susceptible to weathering, which causes rapid changes in the geotechnical properties and durability. This study investigated siltstone samples

Breakage index of weathered soil reflecting breakage level and weathering degree

open access: yesKSCE Journal of Civil Engineering, 2009
The particle of weathered soil is easily broken by stress, which is significantly influenced by environments and field conditions. In addition, the degree of weathering of soil leads to the change of the breakage level of the soil and the strength parameters of its structure.

A preliminary study on the new geotechnical weathering index in the evaluation of altered biotite granite

open access: yes, 2018
The existing chemical index of alteration has a difficulty to evaluate the degree of weathering in biotite granites due to an assumption that K2O content decreases along with Na2O, CaO, and MgO.

Chemical Weathering and Climate_v1

open access: yes, 2020
The dataset includes chemical depletion data across the globe for granitic, basaltic, and shale soils along with precipitation (P) and potential evapotranspiration (PET) data, and has been used for classifying weathering regimes according to the dryness ...

Circadian‐Inspired Hydrogel Moisture Electricity Generation

open access: yesAdvanced Science, EarlyView.
A circadian‐inspired hydrogel moisture‐electric generator enables sustainable electricity generation by autonomously current direction switching between daytime and nighttime. This reversible output is accompanied by inversion of the internal water gradient, which effectively reduce hydrogel fatigue and offers a new strategy for harvesting diurnal ...
