Relationship Between Thermal Conductivity, Mineral Composition and Major Element Composition in Rocks from Central and South Germany

Geosciences
Thermal conductivity is a decisive parameter in all geothermal applications. In addition to the influencing factors of density, saturation, porosity, temperature and pressure, it is, above all, the geochemical and mineralogical composition that ...

Magnetic Supraparticles as Identifiers in Single‐Layer Lithium‐Ion Battery Pouch Cells

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
As an alternative to externally applied optical identifiers, magnetic supraparticles (SPs) can be used for contactless identification of lithium‐ion battery pouch cells via magnetic particle spectroscopy. This study validated the integration and detection of magnetic markers in three model scenarios.

Chemical and mineralogical characterization of silicon manganese iron slag as railway ballast

REM: International Engineering Journal
In nature, metal ores such as iron, lead, aluminum and others are found in an impure state, sometimes oxidized and mixed with silicates of other metals. During casting, when the ore is exposed to high temperatures, these impurities are separated from the

Microbialite cathodoluminescence: A tool for investigating palaeoredox conditions, alteration histories and primary textures across time

The Depositional Record, EarlyView.
Microbialites are common throughout the rock record and key to our understanding of Earth history, yet a relatively common microscopy technique—cathodoluminescence (CL)—has not previously been leveraged to understand them. In this contribution, we examine microbialites of varying ages (modern to Proterozoic) with CL and report on the patterns and ...

Gels for CO2 geo‐storage and conformance control: A systemic review of behavior and performance

Deep Underground Science and Engineering, EarlyView.
This review provides a systemic evaluation of potential sealants used in CO2 subsurface storage practices. Critical analyses of how external factors like CO2, pH, brine salinity and hardness, rock mineralogy, pressure, temperature, and injectivity could affect the performance of different sealants are provided. Abstract Carbon capture and storage (CCS)

Halloysite‐Based X‐Ray‐Activated Persistent Luminescent Hydrogels Enable Multiple‐Level Encryption and Dual‐Locked Camouflage

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
X‐ray‐activated persistent luminescent hydrogels with self‐healing properties were facilely developed based on the plasma‐assisted surface modification of halloysite nanotubes. Exploring multiple‐level encryption technologies and extra safety decoding ways to prevent information leakage is of great significance and interest, but is still challenging ...
