Influence of Niobium on the Beginning of the Plastic Flow of Material during Cold Deformation
The Scientific World Journal, 2013 Investigations were conducted on low-carbon steel and the steel with same chemical composition with addition of microalloying element niobium. While tensile testing was carried out, the thermographic measurement was tacking place simultaneously.

Experimental demonstrations of high-Q superconducting coplanar waveguide resonators [PDF]
, 2013 We designed and successfully fabricated an absorption-type of superconducting coplanar waveguide (CPW) resonators. The resonators are made from a Niobium film (about 160 nm thick) on a high-resistance Si substrate, and each resonator is fabricated as a ...

Formation of niobium oxides by electrolysis from acidic aqueous solutions on glassy carbon
Macedonian Journal of Chemistry and Chemical Engineering, 2019 In this study niobium oxide films were formed without peroxo-precursors from three different mixed acidic aqueous solutions on glassy carbon. Linear sweep voltammetry and potential step were techniques used for electrochemical experiments.
