Study of SnO2 gels by Eu3+ fluorescence spectroscopy
(1992-12-01)
Eu3+ fluorescence spectroscopy was used as a probe to study the changes in local arrangements of tin oxyhydroxide precipitate → sol → gel → glass conversion. Electronic transition intensities and 5D0 excited state lifetime ...
Spectroscopic and asteroseismic analysis of the secondary clump red giant HD 226808
(IOP Publishing, 2020)
Differential rotation in rapidly rotating early-type stars. I: motivations for combined spectroscopic and interferometric studies.
(Edp Sciences, 2011-02)
Context. Since the external regions of the envelopes of rapidly rotating early-type stars are unstable to convection, a coupling may
exist between the convection and the internal rotation.
Aims. We explore what can be ...
Thermal and spectroscopic study of the lanthanide 2-aminoterephthalate compounds in the solid state
(Springer, 2014-07-01)
Lanthanides 2-aminoterephthalate compounds were synthetized and characterized on the basis of TG-DTA data in order to study their thermal behavior, as well as to establish hydration grade and stoichiometry, while TG/FTIR ...
Correction to: Thermal, spectroscopic and antimicrobial activity characterization of some norfloxacin complexes
(2018-02-21)
In the original publication, the fifth author’s given name was misspelled as “Gabriel”. The corrected name is given in this erratum. The original article has been corrected.
A spectroscopic and chemometric study of virgin olive oils subjected to thermal stress
(Elsevier, 2011-07)
The paper describes a study of thermal stress of three different samples of virgin olive oil in terms of oxidative stability. Fatty acid composition, evaluation of oxidative stability under forced conditions (OSI), ...
