Metacarbonate rocks of the Paleoproterozoic Khapchan series (southeastern part of the Anabar Shield): mineral and chemical composition, metamorphic conditions

open access: yesЗаписки Горного института
The mineral composition of metacarbonate rocks (silicate marbles and carbonate-silicate rocks) of the Khapchan series (southeastern part of the Anabar Shield) was studied, and the PT (pressure and temperature)-parameters of their formation were ...

Rapid determination of organic carbon in carbonate rocks.

open access: yesJournal of the Japanese Association for Petroleum Technology, 1990
A rapid method for determination of organic carbon in carbonate rocks has been developed to replace the normal procedure in which carbonate samples are pretreated with hydrochloric acid to decompose carbonate minerals. The method involves dry combustion of organic material in an oxygen stream and subsequent measuring of carbon dioxide (CO2) generated ...

Strength, stability, and microstructure of simulated calcite faults sheared under laboratory conditions spanning the brittle-plastic transition

open access: yes, 2015
Destructive earthquakes are commonplace in tectonically-active carbonate-bearing terrains, often leading to severe economic damage and major loss of life (e.g. the Apennines, Italy).

Secreted Nonstructural Protein 3 is a Pathogenic Determinant of Orbivirus

open access: yesAdvanced Science, EarlyView.
This study uncovers a conserved PIP2‐dependent secretory pathway of orbivirus NS3 that induces vascular leakage. Pharmacological disruption of PIP2‐NS3 interaction significantly reduces viral pathogenicity and provides protective efficacy in murine models, establishing PIP2‐mediated NS3 secretion as both a key virulence determinant and a promising ...

Fractionation of carbon and oxygen isotopes in 13C-rich Palaeoproterozoic dolostones in the transition from medium-gradegreenschist facies: a case study from the Kola Superdeep Drillhole [PDF]

open access: yes, 2003
Samples from the Kola Superdeep Drillhole (12 262 m), a deep drillhole (1060 m), and from the surface, seaprated by only around 10 km, provided a unique opportunity for direct tracing of delta(13)C and delta(18)O changes through a low- to high-grade ...

Faster and Durable: A Cell‐to‐System Validation of a Low‐Degradation Fast‐Charge Protocol for Li‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
A physics‐based framework resolving graphite phase‐separation dynamics establishes a predictive, degradation‐aware fast‐charging methodology for commercial Li‐ion batteries. The resulting model‐informed protocol achieves 20%–80% state‐of‐charge in 14 min while matching the long‐term degradation of a commercial 25‐minute EV strategy.

Variation of Visean strata across the midi thrust, Belgium [PDF]

open access: yes, 1986
The Viséan strata of southern Belgium, between Namur, Aachen, Comblain-au-Pont and Dinant, record the deposition of shallow water carbonates along the southern margin of the Brabant Massif.

Flexible Unusual Ternary‐Component Graded‐Modulus Dielectric Films with High‐Density Capacitive Energy Storage

open access: yesAdvanced Science, EarlyView.
Hierarchical PP–LSR107–BaTiO3 nanocomposite films are fabricated by one‐step extrusion and stretching for roll‐to‐roll manufacture, combining high energy storage and processing flexibility. LSR107 surrounds BaTiO3‐rich regions, locating amorphous PP, decreasing defects, and introducing deep traps that homogenize the electric field and suppress charge ...

Erosion characteristics and pore structure of carbonate rocks under long-term immersion

open access: yesShuiwen dizhi gongcheng dizhi
Carbonate rocks are widely distributed in Guizhou Province, where groundwater-driven dissolution often leads to engineering geological problems such as karst leakage, collapse, and foundation stability.
