Desenvolvimento de um dispositivo para ensaio térmico de revestimento do tipo barreira térmica
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2018-06-19)
Data and information collection for heat interaction systems in thermal barrier coating (TBC) components, under the influence of substrate cooling, as in gas turbines and diesel engines, are usually expressed through models ...
Synthesis, characterization and thermal behaviour of solid-state compounds of 4-methoxybenzoate with some bivalent transition metal ions
(2005-05-18)
Solid-state M-4-MeO-Bz compounds, where M stands for bivalent Mn, Co, Ni, Cu and Zn and 4-MeO-Bz is 4-methoxybenzoate, have been synthesized. Simultaneous thermogravimetry-differential thermal analysis (TG-DTA), differential ...
Solid-state compounds of 2-methoxybenzylidenepyruvate with some bivalent metal ions - Synthesis, characterization and thermal behavior studies
(Springer, 2008-03-01)
Solid-state M-2-MeO-BP compounds, where M represents bivalent Mn, Fe, Co, Ni, Cu, Zn and 2-MeO-BP is 2-methoxybenzylidenepyruvate have been synthesized. Simultaneous thermogravinietry-differential thermal analysis (TG-DTA), ...
Metal leaching, acidity, and altitude confine benthic macroinvertebrate community composition in Andean streams
(Wiley, 2014)
Andean streams drain metal-rich bedrock and are subjected to an extreme altitude gradient, which may create highly selective conditions for life. The aim of the present study was to evaluate the combined effects of metals ...
Towards field trace metal speciation using electroanalytical techniques and tangential ultrafiltration
(2016-05-15)
In this work we propose a trace metal speciation methodology to determine the total, free and ultrafiltered (<1 KDa) metal fractions using electrochemical methods (SCP and AGNES) and tangential ultrafiltration (UF) experiments ...
Heavy metal availability in pelargonium hortorum rhizosphere: Interactions, uptake and plant accumulation
(Taylor & Francis, 2012-06)
The rhizosphere is a key area for the plant metal uptake. We studied heavy metal availability in the rhizosphere and the bulk soil, the interactions between metal ions, and their effects on heavy metal uptake and accumulation ...
