Wettability decay in an oil-contaminated waste-mineral mixture with dry-wet cycles [PDF]
, 2015 The dependency of soil particle wettability on soil water content implies that soils subjected to drying-wetting cycles become wettable with wetting and water repellent with drying.

Delayed compression and breakage of crushed mudstones due to the drying/wetting and temperature cycles [PDF]
E3S Web of ConferencesSoft sedimentary rocks, especially mudstones, disintegrated or crumbled when subjected to cyclic drying and wetting, known as slaking, which was the cause of severe slope failures and ground settlement.

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

Effect of wetting and drying cycles on the durability of bio-cemented soil of expressway slope
International Journal of Environmental Science and Technology, 2021 Cyclic wet-dry is one of the influential weathering agents which can rapidly alter the mechanical properties of soils, limiting their durability and consistent performance.

Reversible and irreversible dimensional changes of heat-treated wood during alternate wetting and drying [PDF]
, 2017 Spruce wood specimens were heat-treated in saturated water vapor (steaming) and in the absence of moisture (dry heating) at 120–180 °C, and their wet volumes were measured during alternate wetting and drying cycles.

Impact of Wetting–Drying Cycles on the Mechanical Properties and Microstructure of Wood Waste–Gypsum Composites [PDF]
, 2019 Large amounts of wood waste are generated each year in the world. In an attempt to identify a good recovery option for those residues, wood waste from construction and demolition works were used as raw materials in gypsum plasters.

Dry/Wet Cycling and the Thermodynamics and Kinetics of Prebiotic Polymer Synthesis [PDF]
Life, 2016 The endoergic nature of protein and nucleic acid assembly in aqueous media presents two questions that are fundamental to the understanding of life’s origins: (i) how did the polymers arise in an aqueous prebiotic world; and (ii) once formed in some manner, how were they sufficiently persistent to engage in further chemistry.
