The determination of the solubility of hafnium oxide in aqueous solution by the radioactive tracer technique [PDF]

, 1950
To date, there is no information in the open literature concerning the solubility of hafnium oxide in water other than the fact that it is very insoluble.

Tamper‐Responsive Physical Unclonable Functions via Graphene‐Interlayered Block Copolymer Random Structures

Advanced Materials, EarlyView.
Self‐invalidating multilayer physical unclonable functions (PUFs) integrate fingerprint‐like metal nanopattern bilayers from block copolymer templates with highly reactive reduced graphene oxide (rGO) interlayers. This tamper‐responsive architecture blocks all unauthorized physical and chemical replication attempts while autonomously deactivating ...

The Modelling of the Solids Solution Formation Process in Systems In2O3-HfO2 at Heating in Air [PDF]

Журнал нано- та електронної фізики, 2010
The ionic radiuses for cations, namely, for indium, hafnium, anion, and anion vacancy on the Templiton and Dauben scale, were calculated based on the mathematical models of the solid solution formation in In2O3-HfO2 system. The phase transition in indium

The flexoelectric effect in Al-doped hafnium oxide

, 2018
After the observation of ferroelectric HfO2, interest in ferroelectric-based nanoelectronics has been renewed. However, ferroelectrics also show coupling between the electrical polarization and the deformation gradient, defined as flexoelectricity.

Sub‐nm2 Ferroelectric Domains via Charged 180° Walls in ZrO2

Advanced Materials, EarlyView.
Ferroelectric ZrO2${\rm ZrO}_2$ thin films host closely spaced charged 180∘$^{\circ }$ domain walls that vertically compress polar domains beyond their lateral half‐unit‐cell limit. These head‐to‐head and tail‐to‐tail walls show distinct bulk‐like structures, natural oxygen‐mediated stabilization, and highly asymmetric mobility, highlighting new ...

Methanesulfonic Acid as a Dual‐Role Reagent for Porous Polymer Network Design

Advanced Materials, EarlyView.
The design of porous polymer networks (PPNs) using methanesulfonic acid (MSA) as a dual‐role reagent facilitates the synthesis of robust PPNs for specific applications. It also makes the scale‐up process techno‐economically feasible because MSA functions simultaneously as both a solvent and a catalyst for the reaction.

Synthesis of Ti2B2Clx MBenes in Molten Salts From Theoretical and Experimental Perspectives

Advanced Materials, EarlyView.
By integrating a theoretical framework with experiments, Ti2InB2 was selectively etched with ZnCl2 to produce a multilayer (ml) Ti2B2Clx MBene. The In atoms are completely removed, with simultaneous incorporation of chlorine surface terminations. in situ x‐ray diffraction indicates a direct biphasic transformation from Ti2InB2 to ml‐MBene, with no ...

Design and analysis of novel La:HfO2 gate stacked ferroelectric tunnel FET for non-volatile memory applications

Memories - Materials, Devices, Circuits and Systems
Recent experimental studies have shown lanthanum-doped hafnium oxide (La:HfO2) possessing ferroelectric properties. This material is of special interest since it is based on lead-free, simple binary oxide of HfO2, and has excellent endurance property (1 ×

Adaptive Supramolecular Interactions Govern Redox‐Active Molecules in Aqueous Redox Flow Batteries

Advanced Materials, EarlyView.
Adaptive supramolecular interactions overcome the solubility‐stability trade‐off in aqueous redox flow batteries. Hydrophobic anions disrupt intrinsic π–π stacking to enable high solubility, while redox‐state‐dependent spin pairing and cation coordination dynamically stabilize reactive intermediates during operation.
