Sources of uncertainties in modelling black carbon at the global scale [PDF]

open access: yes, 2010
Our understanding of the global black carbon (BC) cycle is essentially qualitative due to uncertainties in our knowledge of its properties. This work investigates two source of uncertainties in modelling black carbon: those due to the use of different ...

Recent increases in terrestrial carbon uptake at little cost to the water cycle

open access: yesNature Communications, 2017
The response of the coupled carbon and water cycles to anthropogenic climate change is unclear. Here, the authors show that terrestrial carbon uptake increased significantly from 1982 to 2011 and that this increase is largely driven by increased water ...

Australian climate-carbon cycle feedback reduced by soil black carbon [PDF]

open access: yes, 2008
Annual emissions of carbon dioxide from soil organic carbon are an order of magnitude greater than all anthropogenic carbon dioxide emissions taken together1.

A Case Study of Waste Scrap Tyre-Derived Carbon Black Tested for Nitrogen, Carbon Dioxide, and Cyclohexane Adsorption

open access: yesMolecules, 2020
Waste scrap tyres were thermally decomposed at the temperature of 600 °C and heating rate of 10 °C·min−1. Decomposition was followed by the TG analysis. The resulting pyrolytic carbon black was chemically activated by a KOH solution at 800 °C.

Adsorption ability of the carbon black for nickel ions uptake from aqueous solution [PDF]

open access: yesHemijska Industrija, 2013
Surface modification can be performed by adsorption of certain organic compounds on the surface of carbon. The main objective of this work was to compare the adsorption ability of acid-modified carbon black with the non-modified one.

Hydropyrolysis: implications for radiocarbon pre-treatment and characterization of Black Carbon [PDF]

open access: yes, 2010
Charcoal is the result of natural and anthropogenic burning events, when biomass is exposed to elevated temperatures under conditions of restricted oxygen.

Contents of black carbon in some anthrosols from Zhejiang Province

open access: yes浙江大学学报. 农业与生命科学版, 2010
To understand the effects of human activity on accumulation of black carbon in soils, 251 surface soil samples were collected from Zhejiang Province. The soil samples had different land uses, including urban green space, road in urban area, manufacture ...

BIOMASS BURNING RELATED POLLUTIONS AND THEIR CONTRIBUTIONS TO THE LOCAL AIR QUALITY IN HONG KONG [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
In this study, we present a quantitative estimation of the impacts of biomass burning emissions from different source regions to the local air quality in Hong Kong in 2014 using global chemistry transport model simulations, sun photometer measurements ...

Isotopes in pyrogenic carbon: a review [PDF]

open access: yes, 2012
Pyrogenic carbon (PC; also known as biochar, charcoal, black carbon and soot) derived from natural and anthropogenic burning plays a major, but poorly quantified, role in the global carbon cycle.

CARBON MODIFICATION OF BITUMEN

open access: yesВестник СибАДИ, 2019
Introduction. The causes of premature destruction of asphalt concrete coatings are aging and low quality of bitumen. The paper describes the methods for improving the bitumen properties.
