Study of hydration of cement pastes added with used catalytic cracking catalyst (FCC) from a colombian refinery

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2013
This paper analyzes the effect of the incorporation of industrial waste from an oil refinery in Colombia, known as used catalytic cracking catalyst (FCC), in the hydration process of cementitious pastes. For this purpose, ordinary Portland cement pastes

Use of Hydration Inhibitors to Improve Bond Durability of Aluminum Adhesive Joints [PDF]

open access: yes, 1985
An investigation is conducted of the mechanisms by which nitrilotris methylene phosphonic acid (NTMP) and related compounds are adsorbed onto oxidized aluminum surfaces to inhibit hydration and increase the durability of adhesive bonds formed with ...

Microstructure of Hydrated Products of Sealed Alumite

open access: yesJournal of the Metal Finishing Society of Japan, 1965
Absorbing power of anodized oxide coating of aluminium (alumite) is destroyed by boiling water or super heated steam sealing. The sealing is performed by hydration of alumina (anhydrous and amorphous γ-Al2O3) formed by anodizing. The hydrated products have been considered to bear a resemblance to boehmite in crystallins structure.

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

open access: yesAdvanced 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.
