Fossil organic carbon utilization in marine Arctic fjord sediments by subsurface micro-organisms
Rock-derived or petrogenic organic carbon has traditionally been regarded as being non-bioavailable and bypassing the active carbon cycle when...

The Lunar Breccia Dhofar 1442: Noble Gases, Nitrogen, and Carbon Released by Stepwise Combustion and Crushing
Stepwise crushing and combustion methods were applied to study the KREEP-rich lunar breccia Dhofar 1442, the clastic material of which is cemented by...

Prototypes of New Radiopharmaceuticals Based on Carbon Nanomaterials: Nanodiamonds Versus Nanotubes
Radiopharmaceuticals (RPs) in nuclear medicine can include radioactive isotope carriers, which are often nanoparticles of various nature. This review... -
Palaeozoic cooling modulated by ophiolite weathering through organic carbon preservation
Ophiolite obductions in the tropics are coeval with Phanerozoic glaciations. The exposure of mafic and ultramafic rocks is thought to trigger cooling...

An isotope, elemental, and n-alkane baseline for organic matter sources in sediments of high-altitude lakes in the Uinta Mountains, Utah, USA
This research provides a critical baseline for chemical and macromolecular characteristics of organic matter (OM) sources in high-elevation lake...

Assessment of carbon isotopic signature of Daphnia ephippia as a proxy for past carbon transfers to pelagic food webs in Jura lakes
Previous studies suggested that past changes in carbon sources and pathways in pelagic food webs can be investigated using carbon isotopic analysis (δ

Experimental Characterization of PM2.5 Organic Carbon by Using Carbon-fraction Profiles of Organic Materials
Organic aerosols (OA) in the atmosphere have complex emission sources and formation processes that must be determined to understand the OA...

Effect of Carbon on the Melting Behavior of a Mold Powder under High Heating Rates
Mold powders used for the continuous casting of steels contain different carbon carriers controlling the melting behavior. During melting, carbon...

Elemental interactions between pore water and lake sediments with their environmental significance: a case as Holocene sediments in Guozha Co, northwestern Tibetan Plateau
Elements in lake sediments and lake water were commonly used in the reconstruction for the paleoenvironment and paleoclimate, and also enriched into...

Comparison of log-ratio and log10 chemical elemental data analysis of Central Amazonian pottery and archaeological implications
The additive log-ratio (alr) transformation is recommended as one of the most robust data transformations for multivariate analysis of archaeometric...

Anthropogenic impacts on mud and organic carbon cycling
Fine-grained muds produced largely from rock weathering at the Earth’s surface have great influence on global carbon cycling. Mud binds and protects...

Fabricating modified carbon of oak fruit for adsorption of fluoride and nitrate from aqueous media: isotherm and kinetic models
Fluoride and nitrate are one of the developed compounds that can enter water resources in different ways. The present research examines the...

Deep CO2 release and the carbon budget of the central Apennines modulated by geodynamics
Recent studies increasingly recognize the importance of critical-zone weathering during mountain building for long-term CO 2 drawdown and release....

Soil carbon in tropical savannas mostly derived from grasses
Tropical savannas have been increasingly targeted for carbon sequestration by afforestation, assuming large gains in soil organic carbon (SOC) with...

Temporal patterns in sediment, carbon, and nutrient burial in ponds associated with changing agricultural tillage
Lakes and ponds play a disproportionate role in retaining sediment, carbon, nitrogen, and phosphorus, potentially mitigating negative environmental...

Non-hydrothermal saddle dolomite in Upper Cambrian dolostones of Tarim Basin: evidence from C–O–Sr isotopic and in-situ trace elemental studies
The Upper Cambrian dolostones in the Tarim Basin are interpreted to be intensely altered by hydrothermal fluids during the burial diagenesis, and the...
