Achieving High ON State Current through Ferroelectric Polarization‐Dependent Interfacial Resistance Switching in Undoped Orthorhombic HfO2 Films

open access: yesAdvanced Functional Materials, EarlyView.
Ferroelectric tunnel junction devices based on epitaxial undoped ferroelectric HfO2 films demonstrate stable switching endurance of over 106 switching cycles, low write voltages of ±3 V, 16 measured resistance states, and neuromorphic capability.

Amine-modified mesoporous SiO2 spheres (MSS-(x) APTMS) as a promising CO2 sorbent

open access: yesJPhys Energy
The design of effective CO _2 adsorbents requires high adsorption capacity and selectivity. In this study, we developed a hybrid organic–inorganic sorbent by functionalizing mesoporous silica spheres (MSSs) with aminopropyltriethoxysilane (APTMS) to ...

Tangent bundle of pseudo-sphere and Non-null slant ruled surfaces

open access: yes, 2023
Abstract A unique type of ruled surface called a slant ruled surface has some fixed directions in the space and Frenet vectors that form a constant angle with one another. In this study, we construct the novel approximation for this slant ruled surface, also known as a non-null slant ruled surface, which was obtained by the striction curve of ...

Exploring an Alternative to mRNA Vaccine Cold Chain Storage: MRNA‐Lipid Nanoparticle Stability When Dried in a Polymer Matrix

open access: yesAdvanced Functional Materials, EarlyView.
The nanostructure, size, and function of mRNA‐loaded lipid nanoparticles are evaluated before drying, within polymer microneedles, and after rehydration. The results reveal the polymer and LNP loadings required to recover nanostructure and preserve the delivery performance in dry‐state formulations.

Titanium Suboxides Responsible for Electronic Anomaly Near Room Temperature in the Ti3C2Tx MXene

open access: yesAdvanced Functional Materials, EarlyView.
Our multi‐technique study reveals that the near‐room‐temperature anomaly in Ti3C2Tx MXene is linked to titanium suboxide nanodomains, including Ti3O5, embedded within the MXene host. Their temperature‐driven transformation provides an alternative explanation to solvent‐ and swelling‐based models and offers new insight into the thermally activated ...

Quantifying Subsurface Weak in‐Plane Magnetization of Mixed Phase BiFeO3 by Scanning Nitrogen Vacancy Magnetometry

open access: yesAdvanced Functional Materials, EarlyView.
We use scanning nitrogen vacancy magnetometry to directly image the weak in‐plane magnetic moments in mixed phase BiFeO3 at the nanoscale and quantify the local magnetic moments to be 18.8±2.0 μB/nm2 in the rhombohedral‐like phase and 1.5±0.6 μB/nm2 in the well‐known non‐magnetic tetragonal‐like phase.

Synthesis of AgBiS2 and AgInS2 Based on Formation Energies in Sulfur‐Rich Reducing Flame

open access: yesAdvanced Functional Materials, EarlyView.
High‐surface‐area AgInS2 and AgBiS2 nanoparticles were synthesized via enclosed flame spray pyrolysis by tuning flame conditions and formation energies to guide phase formation. Flame parameters were tuned to suppress oxides and enable pure sulfide phase growth.
