Tropical ecosystems are under increasing pressure from land-use change and deforestation. Changes in tropical forest cover are expected to affect carbon and water cycling with important implications for climatic stability at global scales. A major roadblock for predicting how tropical deforestation affects climate is the lack of baseline conditions...
In the presented work, tribological interactions of tetrahedral amorphous carbon (ta-C) coatings with variations of sp3 content have been systematically studied in the boundary lubrication regime with emphasis on fatty acid-based lubricants. Manifold phenomena regarding wear and friction have been observed that exceed the conventional understanding...

AbstractA thermodynamic analysis of the oxygen solutions in the carbon-containing Ni–Co melts is performed. The equilibrium constants of the reaction of carbon with oxygen, the activity coefficients at infinite dilution, and interaction parameters for melts differing in composition are determined at 1873 K. The dependences of the oxygen solubility ...

AbstractAmong forest fires, underground (peat) fires lead in terms of the amount of material burned per unit area and, consequently, the impact on climate change, but they differ in the complexity of assessing the loss of soil carbon and its emissions to the atmosphere. Using the example of the 2010 forest and peat fire in Moscow oblast (an area of...

AbstractThe accumulation of carbon of organic matter by forest phytocenoses during photosynthesis is their most important function, mitigating climate change on the Earth. The literature provides data that the territory of the Russian Federation is a large sink of atmospheric carbon. However, the estimates of the sink, as well as the values of th...

Colorectal cancer (CRC), the third most common type of cancer, is the second leading cause of cancer-related mortality rates worldwide. Although modern research was able to shed light on the pathogenesis of CRC and provide enhanced screening strategies, the prevalence of CRC is still on the rise. Studies showed several cellular signaling pathways d...

We report a previously undescribed member of the Helotiales that is superabundant in soils at two maritime Antarctic islands under Antarctic Hairgrass ( Deschampsia antarctica Desv.). High throughput sequencing showed that up to 92% of DNA reads, and 68% of RNA reads, in soils from the islands were accounted for by the fungus. Sequencing of the lar...

Nutritional epigenetics is a rapidly expanding field of research, and the natural modulation of the genome is a non-invasive, sustainable, and personalized alternative to gene-editing for chronic disease management. Genetic differences and epigenetic inflexibility resulting in abnormal gene expression, differential or aberrant methylation patterns ...

Charge distribution on every atom of carbon matter in four dimension forms (cluster, fullerene, atomistic carbon chain, nanotube, graphene, surface and solid) was investigated by the first-principles calculation. It is found that the charge distribution in most of these materials is inhomogeneous, even in one certain solid phase. We found that if o...

Currently, 3D printing is an affordable technology for industry, healthcare, and individuals. Understanding the mechanical properties and thermoplastic behaviour of the composites is critical for the users. Our results give guidance for certain target groups including professionals in the field of additive manufacturing for biomedical components wi...
