The central role of oxo clusters in zirconium- and hafnium-based esterification catalysis. [PDF]
Oxo clusters are a unique link between oxide nanocrystals and MOFs, representing the limit of downscaling each of the respective crystals. Here, we show the superior catalytic activity of Zr12O8(OH)8(OOCR)24 clusters, compared to zirconium MOF UiO-66 and

Advanced Science, EarlyView.By overcoming the fixed‐path limitations of conventional machine learning, a heterogeneous graph neural network fundamentally reconstructs material data representation. Integrating variable processing sequences with intrinsic elemental features, this framework enables exploratory optimization across high‐dimensional spaces.

Engineering of Crystal and Domain Structures in Epitaxial Y:HfO2 Thin Films by YSZ Substrate Miscut
Advanced Science, EarlyView.We investigate how YSZ substrate miscut influences crystal structure and domain formation in epitaxial Y‐doped HfO2 thin films. Using magnetron sputtering, high‐resolution X‐ray diffraction, atomic‐resolution scanning transmission electron microscopy, and first‐principles calculations, we systematically examine the characteristics of thickness‐ and ...

Review of processes for the production of hafnium-free zirconium.
, 1970 The three main industrial processes for the production of hafnium-free zirconium are described in terms of their head-end, zirconium-hafnium separation and zirconium metal forming steps.

Advanced Science, EarlyView.The crystalline structure, the atomic numbers of the constituent elementsand the size of MOF crystals each influence their photoluminescence and scintillation properties in distinct ways. Together, these factors provide valuable guidelines for designing systems with optimized performance and tunable timing characteristics, arising from the synergistic ...
