[Investigation of the structure and phase relations of C-S-H gels] [PDF]

open access: yes, 1994
(C-S-H stands for calcium silicate hydrate.) The following areas of study are reported: solution-derived C-S-H, hydration of alite at constant pH, and hydrothermal synthesis of tobermorite.

Dissolution kinetics of C-S-H gel and durability of mortar

open access: yes, 2023
The use of concrete in disposal facilities to store low- and intermediate-level nuclear waste requires that the durability of this material is optimal for the lifetime of these repositories. One of the most important processes that put such durability at risk is the attack of concrete by water with low mineral content and neutral pH, altering its ...

Translophagy—A potential link between autophagy impairment and translational errors

open access: yesFEBS Letters, EarlyView.
Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

The Effect of Microwave Radiation on the Solidification of C-S-H Gels: Its Influence on the Solidified Cement Mixtures

open access: yesGels, 2023
The present paper deals with the properties of hardened cement mixtures that have been exposed to microwave radiation. Microwaves fall under electromagnetic waves (EMW), and the main reason for using EMW radiation is to accelerate the drying of concrete ...

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

open access: yesFEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Effect of alkalis on fresh C–S–H gels. FTIR analysis

open access: yesCement and Concrete Research, 2009
The present study addresses the effect of different concentrations of Na2O on the structure of a composition of fresh C–S–H gels. The gels were synthesized from laboratory reagents, using calcium nitrate as the source of calcium and a sodium silicate solution for the silicon. A 10-M solution of NaOH was used to maintain a pH of over 13 throughout.

Structural and biochemical analysis of a B12 superbinder

open access: yesFEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Stoichiometrically controlled C-(A)-S-H/N-A-S-H gel blends via alkali activation of synthetic precursors [PDF]

open access: yes, 2015
The extent to which the composition of the reaction mix affects the formation of a biphasic C–(A)–S–H/N–A–S–H geopolymer framework, and how the interaction of these phases affects geopolymer microstructure, can only be studied by strict stoichiometric ...

Textural and mechanical characterization of C-S-H gels from hydration of synthetic T1-C3S, β-C2S and their blends

open access: yesMateriales de Construccion, 2011
The textural and mechanical characterization of C-S-H gels formed from the hydration of pure T1-C3S, β-C2S and their blends are studied by Nitrogen sorption and nanoindentation experiments.

Nanoindentation Study of Calcium-Silicate-Hydrate Gel via Molecular Dynamics Simulations

open access: yesNanomaterials, 2023
The mechanical properties of calcium-silicate-hydrate (C-S-H) gels in cementitious materials are mainly realized by nanoindentation experiments. There is limited research on the dynamic response of the molecular structure of C-S-H under nanoindentation ...
