Copper-manganese-zinc spinels in zeolites: study of EMR spectra
Nukleonika, 2015 The aim of this study is the application of electron magnetic resonance (EMR) spectroscopy to determine the interactions between NaY and HY zeolites and Cu-Mn-Zn spinels loaded onto the zeolite surfaces.

The Spinel Explorer—Interactive Visual Analysis of Spinel Group Minerals
IEEE Transactions on Visualization and Computer Graphics, 2014 Geologists usually deal with rocks that are up to several thousand million years old. They try to reconstruct the tectonic settings where these rocks were formed and the history of events that affected them through the geological time. The spinel group minerals provide useful information regarding the geological environment in which the host rocks were

MORPHOLOGICAL AND COMPOSITIONAL FEATURES OF CHROMIAN SPINEL FROM MANTLE ULTRAMAFIC ROCKS OF THE NURALI MASSIF (SOUTH URALS) [PDF]
Минералогия, 2019 Accessory chromian spinels of lherzolites and dunites from a mantle section of the Nurali ophiolite massif are described in the paper. Lherzolites typically host anhedral chromian spinel grains associated with olivine, pyroxenes and plagioclase.

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy
Advanced Engineering Materials, EarlyView.This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...
