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

Strength Deterioration Mechanism of Bentonite Modified Loess After Wetting- Drying Cycles [PDF]
Scientific Reports, 2021 Abstract The employment of bentonite modified loess (BML) is a common method of constructing the anti-seepage lining of landfills in the loess region of China, and its long-term secure performance is threatened by wetting-drying (W-D) cycles.

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