Magnetic and Isotopic Analyses Unravel the Abundance and Sources of Magnetic Nanoparticles in Urban PM2.5

Geophysical Research Letters
Magnetic nanoparticles (NPs) are increasingly recognized as an emerging threat to ecosystems and human health, yet their mass concentrations and sources in urban atmosphere remain poorly characterized.

Electrostatic‐Attraction‐Driven Self‐Assembled Graphene‐Disordered Rocksalt Composite Cathode for Lithium‐Ion Batteries

Advanced Functional Materials, EarlyView.
A non‐aqueous, solution‐based graphene‐wrapping strategy is shown to stabilize disordered rocksalt LMTOF cathodes without structural degradation. The graphene‐wrapped cathode suppresses oxygen loss and parasitic interfacial reactions, lowers impedance growth, and delivers improved cycling stability and rate capability compared with conventional ball ...

Orbital Evolution of Planetary Systems [PDF]

Symposium - International Astronomical Union, 2004
It is significant that the orbits of the planets in the solar system are very nearly circular, except for Mercury and Pluto where, conceivably, due to their comparatively small sizes, the tidal forces have played a less active role. Most of the suspected planets orbiting pulsars have nearly circular orbits. These systems tend to have minimum energy and

Giant Electrostriction in Halide Perovskites Revisited With Double‐Modulation Interferometry

Advanced Functional Materials, EarlyView.
A giant electrostrictive effect in lead halide perovskites had been reported previously. This work uses sensitive interferometry to measure the electromechanical response of various halide perovskite samples. The results reveal no intrinsic electrostrictive compression. Instead, the materials expand primarily under an applied electric field as a result

Microplastic Analysis in Soil Using Ultra-High-Resolution UV–Vis–NIR Spectroscopy and Chemometric Modeling

Microplastics
The study of microplastics (MPs) in soils is impeded by similarities between plastic and non-plastic particles and the misidentification of MP by current analytical methods such as visual microscopic examination.

Radiative transfer and inversion codes for characterizing planetary atmospheres: an overview

Frontiers in Astronomy and Space Sciences, 2023
The study of planetary atmospheres is crucial for understanding the origin, evolution, and processes that shape celestial bodies like planets, moons and comets.

Transparent Perovskite Light‐Emitting Diodes with Conductive Oxide Top Electrodes

Advanced Materials, EarlyView.
Transparent perovskite light‐emitting diodes (TrPeLEDs) enable simultaneous display and transparency, expanding application possibilities. Using a metal oxide buffer layer and pulsed laser deposition, TrPeLEDs with diverse compositions and architectures are demonstrated.

Simultaneous Evolutionary Fits for Jupiter and Saturn Incorporating Fuzzy Cores

The Astrophysical Journal Letters
With the recent realization that there likely are stably stratified regions in the interiors of both Jupiter and Saturn, we construct new nonadiabatic, inhomogeneous evolutionary models with the same microphysics for each that result at the present time ...
