Macro-micro tests of cohesive soil under varied normal and shear stresses subjected to drying-wetting cycles

Journal of Rock Mechanics and Geotechnical Engineering
The mechanical behavior of cohesive soil is sensitized to drying-wetting cycles under confinements. However, the hydromechanical coupling effect has not been considered in current constitutive models.

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films

Advanced Functional Materials, EarlyView.
Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...

Effect of drying-wetting cycles on triaxial compression mechanical properties of sandstone [PDF]

, 2016
To investigate the geological hazards caused by the action of drying-wetting cycle on rocks, we conducted a conventional triaxial compression test on sandstone under a high number of repeated drying-wetting cycles.

Regulated Ion‐Diffusion Hydrogels for Subtle and Multimodal Temperature‐Strain Sensing in Wound Monitoring

Advanced Functional Materials, EarlyView.
A soft, dual‐channel hydrogel patch enables simultaneous detection of wound temperature and strain by integrating ion‐diffusion‐mediated thermoelectric and resistive sensing. The conformal design maintains stable performance during motion, capturing subtle inflammatory and mechanical changes for continuous wound monitoring.

Impact of wetting–drying cycles on swelling behavior of clayey soils modified by silica fume [PDF]

, 2011
Expansive clayey soils contain silicate clay minerals that have the potential for swelling and shrinkage under changing moisture contents. Cyclic wetting drying phenomena can cause progressive deformation of expansive clayey soils, which may affect ...

Tuning Separator Chemistry: Improving Zn Anode Compatibility via Functionalized Chitin Nanofibers

Advanced Functional Materials, EarlyView.
Nanochitin derived from waste shrimp shells is used to fabricate separators for aqueous zinc batteries. By tuning the density of amine and carboxylic surface groups, water mobility at the separator interface is controlled, promoting uniform zinc deposition, suppressing dendrite growth, and enabling exceptional cycling stability exceeding 2000 h ...
