Thermal behavior, spectroscopic study and evolved gas analysis (EGA) during pyrolysis of picolinic acid, sodium picolinate and its light trivalent lanthanide complexes in solid state
(2016-05-01)
Synthesis, characterization, and thermal behavior of light trivalent lanthanide picolinate (La-Gd, except Pm) as well as the thermal behavior of picolinic acid and its sodium salt were investigated employing elemental ...
Thermoanalytical and spectroscopic characteristics of young and old leaves powder and methanolic extracts of Niedenzuella multiglandulosa
(2018-04-01)
Niedenzuella multiglandulosa is a plant species known for having high toxicity and to cause death in cattle and sheep, promoting economic losses in Brazilian trade balance difficult to estimate. This work aims to evaluate ...
Thermal analysis (TG–DSC, DSC–microscopy and EGA) and characterization of heavy trivalent lanthanides and yttrium isonicotinates
(2019-01-01)
The trivalent lanthanide isonicotinates were synthesized to obtain stoichiometry Lu(IN) 3 and Ln(IN) 3 ·2H 2 O (Ln = Tb to Lu, and Y; IN = isonicotinate). A deep study of the thermal behavior in oxidant (air) and inert (N ...
