Electrode and Microstructure Dependence of Oxygen Diffusion in Ferroelectric Hafnium Zirconium Oxide Thin Films

Advanced Functional Materials, EarlyView.
Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights

π‐Radical Cascades to Peri‐Fused Triangulene Dimers

Angewandte Chemie, EarlyView.
We demonstrate the potential of open‐shell molecular graphene fragments as synthons for constructing graphene nanostructures via π‐radical cascades. By identifying monoradical intermediates as key selectivity‐determining species and tuning steric effects in a triangulene precursor, we show that reactivity in a formally diradical system can be ...

Combining stable isotope ratios with elemental concentrations to improve the estimation of terrestrial carnivore diets

Global Ecology and Conservation, 2023
Stable isotopes of animal tissue have been used to estimate diet for many consumer species and places, but the ability to assign contributions to all food items is limited by the number of tracers used, and the separation of the tracer data among the ...

Electroacupuncture Improves the Learning and Memory by Modulating Hippocampal Glucose Metabolism through IGF1/IGF1R Signaling in Alzheimer's Disease

Advanced Science, EarlyView.
Electroacupuncture (EA) ameliorates learning and memory function in 5×FAD mice by regulating the brain glucose metabolic network. This neuroprotective effect is closely related to enhancing neuronal energy utilization via the IGF1/IGF1R signaling pathway.

Fluid-driven element mobility resets plagioclase rubidium strontium and barium clocks while potassium feldspar resists

Communications Earth & Environment
Rubidium, cesium, strontium, barium and their isotopes are employed as tracers of magmatic differentiation and fluid-mediated metasomatism, but their mobility during mineral-scale alteration remains uncertain.

Introducing a Precise System for Determining Volume Percentages Independent of Scale Thickness and Type of Flow Regime

Mathematics, 2022
When fluids flow into the pipes, the materials in them cause deposits to form inside the pipes over time, which is a threat to the efficiency of the equipment and their depreciation.

Nanoscale Secondary Ion Mass Spectrometry for Quantifying Membrane Fouling: Fouling Layer Structure and Chemical Interaction

Advanced Science, EarlyView.
Nanoscale secondary ion mass spectrometry (Nano SIMS) is established as a powerful analytical tool to visualize and quantify the membrane fouling layers. ABSTRACT Membrane technology has garnered considerable attention for applications in wastewater treatment and resource recovery. Nevertheless, membrane fouling remains a major barrier, yet the lack of
