Effect of impurities on mechanical relaxation in niobium
(ABM, ABC, ABPol, 2003-12)
Measurements of internal friction as a function of temperature were performed in samples of Nb containing different amounts of substitutional (Zr) and interstitial (O, N) solutes. These data were resolved using the method ...

One-Step Synthesis of Methoxylated Phloroglucinol Derivatives Promoted by Niobium Pentachloride: An Experimental and Theoretical Approach
(2017-06-01)
Phloroglucinol derivatives are an important class of natural compounds featuring the rhodomyrtone derivatives. In this work, the synthesis of compounds with a structure core of rhodomyrtosone I is described using a ...
Determination of the properties of an experimental glass polyalkenoate cement prepared from niobium silicate powder containing fluoride
(Elsevier B.V., 2008-01-01)
Objectives. The purpose of this paper is to modify the conventional calcium fluoro-aluminosilicate glass, which is used in the formation of glass ionomer cements (CIGs) by the niobium addition and to study the properties ...
