Impact of Disorder on Microscopic Superconducting and Normal‐State Responses in a Kagome Metal

Advanced Functional Materials, EarlyView.
Using depth‐resolved, field‐ and pressure‐dependent μSR$\umu{\rm SR}$ measurements, we show that disorder in Ta‐doped KV3Sb5 drives a crossover from nodal to nodeless superconductivity while strongly modifying the normal‐state magnetic response. Our results reveal that disorder affects superconductivity and magnetism in fundamentally different ways ...

Uncovering the Edge of the Polar Vortex

Journal of the Atmospheric Sciences, 2017
Abstract The polar vortices play a crucial role in the formation of the ozone hole and can cause severe weather anomalies. Their boundaries, known as the vortex “edges,” are typically identified via methods that are either frame dependent or return nonmaterial structures and, hence, are unsuitable for assessing material transport ...

Stratospheric Polar Vortex Exerts Different Controls on the Transport of Tropical and Mid‐Latitude Volcanic Aerosols

Geophysical Research Letters
Moderate volcanic eruptions and extreme wildfires in recent two decades have persistently perturbed global stratospheric aerosol loadings. Based on satellite observations and climate model simulations, we find that these events contribute to ∼67% of ...

Mechanically Mutable Matrices: A Hierarchical Investigation of Decellularized Sea Cucumber Collagen as an Adaptable Scaffold Material

Advanced Functional Materials, EarlyView.
Sea cucumber mutable collagenous tissue (MCT) is a remarkable collagen‐based material which can rapidly undergo large changes in stiffness through transiently bound effector proteins. Here, we investigate the hierarchical structure and mechanical response of MCT from Cucumaria frondosa across length scales with a wide range of methods, also exploring ...

The North Atlantic variability structure, storm tracks, and precipitation depending on the polar vortex strength [PDF]

Atmospheric Chemistry and Physics, 2005
Motivated by the strong evidence that the state of the northern hemisphere vortex in boreal winter influences tropospheric variability, teleconnection patterns over the North Atlantic are defined separately for winter episodes where the zonal wind at ...

Volatile Relay Biosensing and Mobile Phone Imaging for Detection of Influenza Virus

Advanced Functional Materials, EarlyView.
Detection of volatile organic compounds is performed via a coupled enzymatic assay with mobile phone detection of the signal. Specific application demonstrated herein is the detection of influenza virus, across multiple levels of biological complexity, up to patient‐derived samples.

Simultaneous Enhancement of Performance and Stability in Dual‐Gate a‐IGZO Thin‐Film Transistors via Single‐Step Laser Annealing for Capacitor‐Less DRAM

Advanced Functional Materials, EarlyView.
A single‐step laser annealing strategy is presented for dual‐gate a‐IGZO TFTs. The steep thermal gradient induces graded oxygen doping in the channel and simultaneous WOx removal at the contacts, enabling concurrent interface and contact engineering.

The Impact of Polar Vortex Strength on the Longitudinal Structure of the Noontime Mid-Latitude Ionosphere and Thermosphere

Remote Sensing
Ground-based ionospheric, CHAMP/STAR, and GOCE satellite neutral density ρ observations under deep solar minimum conditions were used to find whether there is a dependence of longitudinal variations on polar vortex strength. Ionospheric stations at fixed-

Mechanisms of Degradation in Li‐Ion Batteries Under Low Temperature Exposures

Advanced Functional Materials, EarlyView.
Low‐temperature exposures, or freeze‐thaw cycles, are observed to significantly accelerate the degradation of Li‐ion batteries. A combination of electrolyte phase separation and mechanochemical stress leads to reversible and irreversible performance losses.
