Meticulous synthesis methods are crucial for achieving high-purity ZrV2O7. Optimized solid-state synthesis can provide sufficient mixing of precursors, while sol–gel methods effectively produce single-phase materials through near-atomic-level mixing.
Our understanding of negative thermal expansion (NTE) in isotropic materials has matured in recent years. The synthesis of this understanding allows us to identify the likely mechanism of NTE in any new material without needing detailed calculations.
A high-quality Y2Mo4O15 single crystal was grown by the top-seed solution growth method. The negative thermal expansion mechanism of the Y2Mo4O15 crystal has been explored and the space thermal expansion coefficient curve has been calculated.
The Fe element in fully hydrated V35Ti30Cr25Fe10 and ZrTiVNiCrFe facilitates O2 poisoning resistance. The O2 poisoning behavior of high-entropy alloys could be roughly estimated using the molar ratio weighted sum of constituent components.
Based on the relationship between keywords, six typical hydrogen storage alloys in the field of poisoning were investigated.
