Energetics and stability of vacancies in carbon nanotubes
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
In this work we present ab initio calculations of the formation energies and stability of different types of multi-vacancies in carbon nanotubes. We demonstrate that, as in the case of graphene, the reconstruction of the ...
Thermogravimetric analysis of poly(ester-carbonates) and poly(ester-thiocarbonates)
(GORDON BREACH SCI PUBL LTD, 1995)
The thermogravimetric behaviour of poly(ester-carbonates) and poly(ester-thiocarbonates) derived from the diphenol esters 4-hydroxy-phenyl-4-hydroxy-benzoate, 3-hydroxy-phenyl-4-hydroxy-benzoate, 4-hydroxy-phenyl-3-hydro ...
Effect of citrate ions on the electrochemical behaviour of low-carbon steel in borate buffer solutions
(Elsevier B.V., 2004-03-01)
The electrochemical behaviour of cold-rolled low carbon steel was studied on both active and passive potential regions in borate buffer solutions with and without the addition of sodium citrate (NaCit). In the active region ...
Successful application of a commercial cationic surfactant mixture (benzalkonium chloride) as porosity stabilizer in porous carbons fabrication
(Elsevier Science, 2016-11)
Porous carbons (BSPCs) were obtained by carbonization of resorcinol-formaldehyde gels in the presence of cationic surfactants mixture (benzalkonium chloride) which act as porosity stabilizer. The application of an inexpensive ...
Carbon stock variability and aggregate stability in soils of Amazon, Brazil
(2018-06-01)
Converting natural ecosystems into agro-ecosystems often reduces soil organic carbon content by decreasing carbon input, as well as by increasing erosion losses and organic matter decomposition rate. This study aimed at ...
Disintegration and Biodegradation in Soil of PBAT Mulch Films: Influence of the Stabilization Systems Based on Carbon Black/Hindered Amine Light Stabilizer and Carbon Black/Vitamin E
(2019-07-01)
This work characterized the disintegration and biodegradation of aged samples of PBAT films with and without photostabilization additives. The objective is to correlate these processes with properties affected after aging, ...
