Terrestrial carbon cycle: tipping edge of climate change between the atmosphere and biosphere ecosystems

Abstract

Being the tendency to couple with multiple elements, Carbon forms the most complex molecules, which is the basic chemistry of all life forms. As our climate system is inextricably coupled...

Modulation of d-band electron enables efficient CO2 electroreduction towards CO on Ni nanoparticles

“…As depicted in Fig. 4b, the Ni-PCNF electrocatalysts achieved a FE CO in excess of 80% across potential ranges of −0.8 to −1.3 V RHE , peaking at 94% at −1.0 V RHE, and no liquid products were detected by 1 H nuclear magnetic resonance ( 1 H NMR) post a 1 hour electrolysis, as per the results presented in Fig. S10.…”

“…The unrelenting escalation of atmospheric CO 2 concentrations continues to herald a multitude of global environmental challenges. 1 The electrochemical CO 2 reduction reaction technique, which can transform CO 2 into a range of valuable chemicals and fuels, has emerged at the forefront of these endeavors, presenting a visionary paradigm for the valorization of this otherwise deleterious greenhouse gas. 2 A diverse array of reduction products can be obtained with distinct implications for energy and industrial applications in CO 2 RR procedure such as CO, CH 4 , CH 3 COO − , and C 2 H 4 .…”

Impacts of Climate Change and Anthropogenic Activities on the Net Primary Productivity of Grassland in the Southeast Tibetan Plateau

“…This would consider the magnitude and direction of changes in PNPP, ANPP and HNPP, as well as the synergistic or antagonistic effects among the different influencing factors. Finally, various new methods based on machine learning were recently applied to such research, and these methods were demonstrated to be superior to our method in some aspects [51,52]. Anyway, our method is still the most extensively used approach at present for quantifying the impacts of anthropogenic activities and climatic change, due to the relatively simple operation and the easier data acquisition [19].…”

Preliminary Results in Innovative Solutions for Soil Carbon Estimation: Integrating Remote Sensing, Machine Learning, and Proximal Sensing Spectroscopy

“…Soil organic carbon (SOC) is a key component of the global carbon cycle [1][2][3] and stores more carbon than the atmosphere and biosphere combined [4]. Soil organic carbon (SOC) is not only composed of plant residues and animal wastes, but also includes organic matter that has been transformed by a diverse array of soil microorganisms, such as fungi and bacteria.…”
