Studies about the heat of hydration developed in mortars with natural and by-product materials

Materiales de Construccion, 2000
The heat of hydration developed in reactions of mortars and concretes can be sensibly reduced using pozzolanic materials. However, the decrease of the heat of hydration is not directly proportional to the amount of cement substituted, because of the heat

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.
