Exceptional middle latitude electron precipitation detected by balloon observations: implications for atmospheric composition [PDF]

, 2022
Energetic particle precipitation leads to ionization in the Earth\u27s atmosphere, initiating the formation of active chemical species which destroy ozone and have the potential to impact atmospheric composition and dynamics down to the troposphere.

Solar cycle variations of stratospheric ozone and temperature in simulations of a coupled chemistry-climate model [PDF]

, 2006
The results from three 45-year simulations of a coupled chemistry climate model are analysed for solar cycle influences on ozone and temperature. The simulations include UV forcing at the top of the atmosphere, which includes a generic 27-day solar ...

Comparative Insights and Overlooked Factors of Interphase Chemistry in Alkali Metal‐Ion Batteries

Advanced Energy Materials, EarlyView.
This review presents a comparative analysis of Li‐, Na‐, and K‐ion batteries, focusing on the critical role of electrode–electrolyte interphases. It especially highlights overlooked aspects such as SEI/CEI misconceptions, binder effects, and self‐discharge relevance, emphasizing the limitations of current understanding and offering strategies for ...

Propolis‐Based Hybrid Nanoflowers as Multifunctional Nanozymes: Structural Integration of Polyphenols for Enhanced Catalytic and Antioxidant Activity

Chemistry &Biodiversity, Volume 23, Issue 3, March 2026.
ABSTRACT Propolis is a polyphenol‐rich natural resin with well‐documented antioxidant activity; however, its practical application is restricted by poor aqueous solubility and limited stability. Herein, propolis‐based organic–inorganic hybrid nanoflowers (Prp‐Nfs) were synthesized by integrating a propolis extract into a Cu3(PO4)2·3H2O matrix under ...

Middle atmospheric ozone, nitrogen dioxide and nitrogen trioxide in 2002-2011: SD-WACCM simulations compared to GOMOS observations [PDF]

, 2018
Most of our understanding of the atmosphere is based on observations and their comparison with model simulations. In middle atmosphere studies it is common practice to use an approach, where the model dynamics are at least partly based on temperature and

Test Particle Simulations of Dual‐Component Microbursts Observed by BARREL: Effects of Atmospheric Backscattering and Chorus Elements

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Electron microbursts are among the most important loss mechanisms for energetic electrons in the Earth's radiation belts and are often driven by wave‐particle interactions with discrete chorus wave elements. Observations from the Balloon Array for Radiation‐belt Relativistic Electron Losses (BARREL) mission have revealed microburst events with

Influence of the Precipitating Energetic Particles on Atmospheric Chemistry and Climate [PDF]

, 2018
We evaluate the influence of the galactic cosmic rays (GCR), solar proton events (SPE), and energetic electron precipitation (EEP) on chemical composition of the atmosphere, dynamics, and climate using the chemistry-climate model SOCOL.

Polybithiophene‐Based Molecularly Imprinted Polymers: A Comparative Mechanistic Study on Electrochemical Signal Transduction Approaches for Protein Detection

Advanced Sensor Research, Volume 4, Issue 11, November 2025.
This study provides the first detailed comparison of the mechanisms behind differential pulse voltammetry and electrochemical impedance spectroscopy in electropolymerized molecularly imprinted polymer (MIP) sensing platforms. Using cystatin C as a model protein, it reveals how electron transfer processes generate signals and offers evidence‐based ...

Are EEP Events Important for the Tertiary Ozone Maximum? [PDF]

, 2019
Energetic particle precipitation (EPP) increases the production of odd hydrogen (HOX ) species in the mesosphere, which catalytically destroy ozone (O3) in sunlight. Hence, the EPP‐HOX impact on the tertiary O3 maximum (TOM) depends on a complex geometry

HEPPA III Intercomparison Experiment on Electron Precipitation Impacts: 1. Estimated Ionization Rates During a Geomagnetic Active Period in April 2010 [PDF]

, 2022
Precipitating auroral and radiation belt electrons are considered an important part of the natural forcing of the climate system. Recent studies suggest that this forcing is underestimated in current chemistry-climate models.
