1.4 Nm Tobermorite-like Calcium Silicate Hydrate Prepared at Room Temperature from Si(OH)₄ and CaCl₂ Solutions

, 1993
Calcium silicate hydrate prepared at room temperature is known to be an amorphous or a very poorly crystalline material. It has a high surface area and may be a promising new microporous material similar to gyrolites.

Intelligent Polymer Electrolytes for Next‐Generation Zinc‐Based Energy Storage Devices

Advanced Science, EarlyView.
Intelligent polymer electrolytes are organized into a three‐level hierarchy that advances zinc‐based energy storage from passive ion conduction toward active, adaptive, and intelligent operation. Molecular regulation of Zn+ coordination, water activity, desolvation, ion flux, and interfaces underpins adaptive self‐healing, anti‐freezing, adhesion, and ...

Influence of the Ca/Si ratio on the compressive strength of cementitious calcium–silicate–hydrate binders

, 2017
Calcium–silicate–hydrate phases have been synthesized with Ca/Si ratios of 0.83–1.50 and it is demonstrated that the compressive strengths of the C–S–H pastes increase for decreasing Ca/Si ratio for all samples and testing ages.
