Auger parameter of hafnium in elemental hafnium and in hafnium oxide

Surface Science, 2004
Abstract X-ray photoelectron spectroscopy has been used to determine the Auger parameters in elemental hafnium and in hafnium oxide (HfO2). The zirconium Lα line has been used as a source of excitation to study the 3d core levels of hafnium, the 1s core level of oxygen, and the X-ray excited MNN Auger region of hafnium and KVV Auger region of oxygen.

The phase diagrams hafnium-vanadium and hafnium-chromium

Journal of the Less Common Metals, 1968
Abstract The binary systems hafnium-vanadium and hafnium-chromium were determined by means of X-ray, melting point, DTA, and metallographic techniques. In the hafnium-vanadium system, β-Hf dissolves up to 23.5 at.% V (1456 °C), whereas the solid-solubility in α-Hf is less than 2 at.%. Vanadium dissolves up to 4 at.% hafnium.

Oxygen Reduction on Hafnium/Hafnium Carbide Nanoparticles

ECS Meeting Abstracts, 2015
Non-precious metal nanoparticles are attractive candidates for oxygen electrocatalytic reduction in electrochemical energy conversion devices, such as fuel cells and batteries. Here we report for the first time electrocatalytic activity of hafnium/hafnium carbide nanoparticles towards the oxygen reduction reaction (ORR).
