Organic chemical signatures of New Zealand carbonate concretions and calcite fracture fills as potential fluid migration indicators [PDF]
, 2006 Macroscopic calcite crystals are common in sedimenta¬ry strata, occurring both as tectonic veins and also filling one or more generations of septarian rupture or later brittle fractures in calcareous concretions.

Physical Origin of Temperature Induced Activation Energy Switching in Electrically Conductive Cement
Advanced Science, EarlyView.The temperature‐induced Arrhenius activation energy switching phenomenon of electrical conduction in electrically conductive cement originates from structural degradation within the biphasic ionic‐electronic conduction architecture and shows percolation‐governed characteristics: pore network opening dominates the low‐percolation regime with downward ...

Amphibalanus amphitrite begins exoskeleton mineralization within 48 hours of metamorphosis
Royal Society Open Science, 2020 Barnacles are ancient arthropods that, as adults, are surrounded by a hard, mineralized, outer shell that the organism produces for protection. While extensive research has been conducted on the glue-like cement that barnacles use to adhere to surfaces ...

Investigation of the interaction of water with the calcite {1014} surface using ab-initio simulation [PDF]
, 2009 Density functional theory calculations were employed to explore the interaction between water and the {1014} surface of calcite. In addition a defective {1014} surface and stepped surfaces in contact with water were investigated.

Advanced Science, EarlyView.A supramolecular pyroptotic thermal switch encapsulates I3− within β‐cyclodextrin (β‐CD) and undergoes CaCO3 mineralization. Upon lysosomal acidification, CaCO3 is degraded, releasing Ca2+ and I3−. Concurrently, BODIPY activation converts I3− into I2, inducing oxidative stress and Ca2+ overload, which together trigger caspase‐3/GSDME‐mediated ...

The Problem of Formation Destruction in Carbon Dioxide Storage: A Microscopic Model
AlgorithmsIn the context of the current global transition toward low-carbon energy, the issue of CO2 utilization has become increasingly important. One of the most promising natural targets for CO2 sequestration is the terrigenous sedimentary formations found in ...

Advanced Science, EarlyView.We report a chromogenic release‐based assay system with protease‐cleavage peptide‐modified calcium carbonate microspheres for colorimetric detection of Porphyromonas (P.) gingivalis activity. In response to Arg‐specific gingipain secreted by P. gingivalis, the supernatant becomes colored, enabling colorimetric analysis and providing the monitoring of ...
