Expanded Clay Applications in Internal Curing of Concrete

open access: yesEPiC Series in Built Environment, 2020
Internal curing is used to reduce shrinkage and early age cracking of poured concrete. The internal curing process depends on providing internal moisture to hardening concrete using prewetted light weight aggregates, as expanded slates and shales. The main objective of this research is to produce internally cured light-weight concrete mixes to be used ...

Aptamer‐Directed Porous DNA Nanocomposite Hydrogel for Active Pulp Preservation: Immunomodulation, Stem Cell Recruitment and Reparative Dentinogenesis

open access: yesAdvanced Science, EarlyView.
This study presents an injectable DNA‐based porous hydrogel integrating catechol motifs and targeting aptamers for pulpitis management. Upon in situ crosslinking, the scaffold actively recruits endogenous dental pulp stem cells, restores redox homeostasis, and modulates immune responses.

POSSIBILITY OF REUSING EXPANDED CLAY IN GREENHOUSE TOMATO CULTIVATION. PART I. YIELD AND CHEMICAL COMPOSITION OF FRUITS

open access: yesActa Scientiarum Polonorum: Hortorum Cultus, 2012
One of the possibility that allow costs of soilless tomato culture to be reduced is to reuse the same growing medium. Expanded clay is classified as an inert medium, that is, chemically and biologically passive, although some studies indicate the ...

Electrohydraulic Folding Ring Actuators for Radial Contraction

open access: yesAdvanced Science, EarlyView.
This work presents an Electrohydraulic Folding Ring Actuator that combines high‐performance electrohydraulic actuation with origami‐inspired folding geometry to achieve constricting radial actuation. This integration yields significant inner lumen constriction, alongside a gripping force capable of holding objects exceeding four times the actuator's ...

Oxygen‐Driven Structural Reorganization by Trace Water Enabling Fast Li‐Ion Transport in a Pliable Solid Electrolyte

open access: yesAdvanced Energy Materials, EarlyView.
Trace water is acting as a constructive mediator in 2LiCl–GaF3, markedly increasing ionic conductivity while reorganizing local coordination. Hydration creates localized Li+ solvation environments and partially dissociates ion pairs, enhancing Li‐ion mobility.
