Low-carbon operations and production: putting training in perspective
The purpose of this paper is mainly to show how training may support low-carbon operations and production management in a more sustainable organizational context. Design/methodology/approach – A conceptual framework to ...
Monitoring the process of densification of 3D and 4D (tridirectional and tetradirectional) carbon/carbon composites
(Sage Publications Ltd, 2015-05-01)
Carbon fiber reinforced carbon composites can be made by iterative liquid impregnation or gas phase carbon deposition routes. In both cases, at the final processing stage the carbon fiber is embedded in carbon matrix which ...
Carbon nanofibers obtained from electrospinning process
In recent years, reinforcements consisting of carbon nanostructures, such as carbon nanotubes, fullerenes, graphenes, and carbon nanofibers have received significant attention due mainly to their chemical inertness and ...
Nanocrystalline carbon flakes deposited by RF magnetron sputtering
Carbon nanostructures were prepared by RF magnetron sputtering at deposition times from 30 to 120 min and temperatures on silicon substrates from 390 degrees C to 510 degrees C. Scanning and transmission electron microscopy ...
Synthetically useful carbon-carbon and carbon-sulphur bond constructions mediated by carbon- and sulphur-centred radicals in water and aqueous media
(Royal Society of Chemistry, 2011-07)
This account is focused on carbon-carbon, and carbon-sulphur bond-forming reactions through the use of carbon- and sulphur-centred radicals in water, respectively. It intends to show the scope and applications on these ...
Estimates of biomass and fixed carbon at a rainforest in Panama
This paper presents an estimation of the quantity of carbon fixed in trees in a one hectare (ha) plot at the Cerro Pelado-Gamboa Hydrology Tropical Observatory, which is located in the province of Colon, Panama. The ...
Characterization of thin carbon films produced by the magnetron sputtering technique
Thin carbon films containing both amorphous and crystalline structures were produced by RF magnetron sputtering. The depositions of the carbon films were performed on Co buffer layers previously deposited on c-plane (0001) ...
Carbon dioxide emissions under different soil tillage systems in mechanically harvested sugarcane
Soil tillage and other methods of soil management may influence CO 2 emissions because they accelerate the mineralization of organic carbon in the soil. This study aimed to quantify the CO2 emissions under conventional ...
