Artigo IPEN-doc 29899 Characterization of peloids from different regions of Brazil2023 - TORRECILHA, JEFFERSON K.; MENDES, ANA P.T.; THEOPHILO, CAROLINA Y.S.; LINHARES, HORACIO M. da S.M.D.; PAULA, JOSE H. de; SCAPIN, MARCOS A.; GARCIA, RAFAEL H.L.; MARAVER, FRANCISCO; SILVA, PAULO S.C. daIntroduction: Since the early days of humankind, peloids have been used for therapeutic purposes. However, the safety and efficacy of these materials for therapeutic treatments has never been regulated in most of the countries where it is commonly used. Materials and methods: In this study, samples os peloids from different regions of Brazil (´Aguas de S˜ao Pedro, Paraty and Arax´a) were characterized: mineral composition (X-ray diffractometry), physicochemical characteristics (pH, redox potential, moisture, % loss on ignition at 550 ◦C and 1000 ◦C, cooling kinetics, swelling power, specific surface area), concentration of trace elements (X-ray fluorescence, Neutron activation analysis, Graphite furnace atomic absorption spectrometry) and radiological activity (Gamma spectrometry). Results: The results showed great variability in mineral composition, physicochemical characteristics, elemental concentration, concentration of activity and little variation in cooling kinetics. However, this variation is also found when comparing the results with some those presented by other authors. Conclusion: This study concludes that the three peloids studied are good candidates to be used for topical application. Metals and potentially toxic elements present are in concentrations levels that are unlikely to cause risk to health.Resumo IPEN-doc 29266 Determinação de elementos traço em peixes do baixo do Rio Pomba utilizando a técnica de ativação neutrônica2022 - SILVA, KAREM L. da; LINHARES, HORACIO M. da S.M.D.Resumo IPEN-doc 21594 Structural and microstructural analysis of luminescent Tb:KY3F10 nanophosphor using X-ray synchrotron diffraction2015 - ICHIKAWA, R.U.; LINHARES, H.M.S.M.D.; RANIERI, I.M.; TURRILLAS, X.; MARTINEZ, L.G.Artigo IPEN-doc 20764 Size-strain analysis in RE-doped KY3F10 fluorides using X-ray line profile analysis2014 - ICHIKAWA, R.U.; MARTINEZ, L.G.; IMAKUMA, K.; LINHARES, H.M.S.M.D.; RANIERI, I.M.; TURRILLAS, X.Artigo IPEN-doc 20192 Luminescence properties of Yb:Nd:Tm:KYsub(3)Fsub(10) nanophosphor and thermal treatment effects2015 - GOMES, LAERCIO; LINHARES, HORACIO M. da S.M.D.; ICHIKAWA, RODRIGO U.; MARTINEZ, LUIZ G.; RANIERI, IZILDA M.Resumo IPEN-doc 14422 Obtencao de cristais de KYsub(3)Fsub(10) dopados com Tm e Nd pela tecnica de refino por zona2007 - SILVA, H.M.; RANIERI, I.M.; SAMAD, R.E.; BALDOCHI, S.L.; VIEIRA JUNIOR, N.D.; COURROL, L.C.Resumo IPEN-doc 14419 Synthesis and purification of KYsub(3)Fsub(10)2007 - SILVA, HORACIO M. da; BALDOCHI, SONIA L.; RANIERI, IZILDA M.Resumo IPEN-doc 15942 Estudos para a obtenção de cristais de KYsub(3)Fsub(10) com resfriamento controlado sob atmosfera de HF2009 - LINHARES, H.M.S.; COURROL, L.C.; BALDOCHI, S.L.; BERTRAM, R.; RANIERI, I.M.Artigo IPEN-doc 13549 Synthesis and characterization of KYsub(3)Fsub(10)Yb:Nd:Tm crystals2008 - SILVA, H.M.; COURROL, L.C.; BALDOCHI, S.L.; BERTRAM, R.; RANIERI, I.M.Resumo IPEN-doc 13826 Energy transfer rates of KYsub(3)Fsub(10):Yb:Tm:Nd system2008 - COURROL, LILIA C.; SILVA, HORACIO M. da; LIBRANTZ, ANDRE F.H.; RANIERI, IZILDA M.; BALDOCHI, SONIA L.; GOMES, LAERCIO
