Prebiotic condensation through wet–dry cycling regulated by deliquescence [PDF]

open access: yesNature Communications, 2019
AbstractWet–dry cycling is widely regarded as a means of driving condensation reactions under prebiotic conditions to generate mixtures of prospective biopolymers. A criticism of this model is its reliance on unpredictable rehydration events, like rainstorms. Here, we report the ability of deliquescent minerals to mediate the oligomerization of glycine

Silica Precipitation in a Wet–Dry Cycling Hot Spring Simulation Chamber [PDF]

open access: yesLife, 2020
Terrestrial hot springs have emerged as strong contenders for sites that could have facilitated the origin of life. Cycling between wet and dry conditions is a key feature of these systems, which can produce both structural and chemical complexity within protocellular material.

Impact of drying-wetting cycles on the small strain behaviour of compacted clay [PDF]

open access: yes, 2023
Small strain shear modulus (Gmax) is an important parameter for assessing the performance of compacted soils that underlie typical transport infrastructure assets such as railway tracks.

How Do Microplastics Affect Physical Properties of Silt Loam Soil under Wetting–Drying Cycles?

open access: yesAgronomy, 2023
Soil physical properties are the main factors that influence soil fertility and directly affect the soil structure and water storage capacity. Microplastics (MPs), which have caused growing concern with respect to soil pollution, have readily been ...

Unraveling mechanisms underlying effects of wetting–drying cycles on soil respiration in a dryland

open access: yesBiogeochemistry, 2023
Rewetting of dry soils usually stimulates soil carbon (C) emission, a phenomenon known as the Birch effect. Soil C cycling in drylands, which store approximately one third of terrestrial soil organic C (SOC), is strongly affected by wetting–drying cycles.

Effect of Wet-Dry Cycles on the Mechanical Performances and Microstructure of Pisha Sandstone

open access: yesMolecules, 2023
The effects of the wet–dry cycles on the chemical compositions, microstructure, and mechanical properties of Pisha sandstone were experimentally investigated in the current study. A series of uniaxial compression tests were conducted to validate the deterioration of the mechanical property of specimens after wet–dry cycles.

Mechanical behaviour of soil under drying-wetting cycles and vertical confining pressure [PDF]

open access: yes, 2023
A system for preparing soil specimens subjected to drying-wetting cycles whilst under vertical confining pressures is introduced with Clayey soil specimens subjected to different drying-wetting histories, then the relative performance tested using ...

Deterioration Characteristic and Constitutive Model of Red-Bed Argillaceous Siltstone Subjected to Drying-Wetting Cycles

open access: yesLithosphere, 2022
Red-bed argillaceous siltstone is one of main types of rocks composing unstable slopes on both banks of water diversion project from the Yangtze to Huaihe River and is prone to deterioration after subjected to drying-wetting cycle conditions during water
