Atmospheric reactive nitrogen and its dry deposition regimes under anthropogenic influence: Insights from intensive and long-term monitoring in Switzerland

Athanasios Nenes, Andrea Baccarini, Kalliopi Violaki, Ghislain Gilles Jean-Michel Motos, Ali Waseem

Excessive nitrogen deposition from anthropogenic activities poses significant challenges to ecosystems and air quality.1 The atmospheric deposition of ammonium and nitrate plays a critical role in regulating ecosystem productivity and driving particulate m ...

Airborne Microorganisms at Hellenic Atmospheric Aerosol and Climate Change Station in Helmos Mountain (Greece)

Athanasios Nenes

Cultural-based methods of bacteria and fungi and molecular identification of bacteria were combined with parallel continuous measurements of aerosol chemical composition, number size distribution, ice-nucleating concentration, and fluorescent particle size ...

Millisecond-time-scale Controlled Freeze-quench for Solute-intermediate Analysis by Solid-state Nmr

Tristan Axel Georges

Crystallization is a fundamental process in biomineralization, yet its complexity increases significantly in non-classical pathways of nucleation and growth, where numerous intermediates exist between free ions in solution and the final crystalline phase. ...

Chiral Phosphoric Acid-catalyzed Enantioselective Higher-order Cycloadditions: Temperature-dependent Periselectivity

Jieping Zhu, Matthew Wodrich

Higher-order cycloadditions (HOCs) are powerful tools for constructing complex cyclic structures, but their synthetic utility is often limited by poor periselectivity and challenges in achieving high diastereo- and enantioselectivity. Herein, we report a c ...

Wildfire and African dust aerosol oxidative potential, exposure and dose in the human respiratory tract

Athanasios Nenes

Exposure to wildfire smoke and dust can severely affect air quality and health. Although particulate matter (PM) levels and exposure are well -established metrics linking to health outcomes, they do not consider differences in particle toxicity or depositi ...

Recent improvements and maximum covariance analysis of aerosol and cloud properties in the EC-Earth3-AerChem model

Paraskevi Georgakaki

Given the importance of aerosols and clouds and their interactions in the climate system, it is imperative that the global Earth system models accurately represent processes associated with them. This is an important prerequisite if we are to narrow the un ...

Implementation of the ISORROPIA-lite aerosol thermodynamics model into the EMAC chemistry climate model (based on MESSy v2.55): implications for aerosol composition and acidity

Athanasios Nenes

This study explores the differences in performance and results by various versions of the ISORROPIA thermodynamic module implemented within the ECHAM/MESSy Atmospheric Chemistry (EMAC) model. Three different versions of the module were used, ISORROPIA II v ...

Gas Sensing with Rotary-Wing Nano Aerial Vehicles

Chiara Ercolani

Harmful chemical compounds are released daily in warehouses, chemical plants and during environmental emergencies. Their uncontrolled dispersion contributes to the pollution of the atmosphere and threatens human and animal lives. When gas leaks occur, the ...

Resilience of aerobic methanotrophs in soils; spotlight on the methane sink under agriculture

Meret Aeppli, Wenyu Gu

Aerobic methanotrophs are a specialized microbial group, catalyzing the oxidation of methane. Disturbance-induced loss of methanotroph diversity/abundance, thus results in the loss of this biological methane sink. Here, we synthesized and conceptualized th ...

Urban boundary-layer flows in complex terrain: Dynamic interactions during a hot and dry summer season in Phoenix, Arizona

Aldo Brandi

Anthropogenic modification of natural landscapes to urban environments impacts land-atmosphere interactions in the boundary layer. Ample research has demonstrated the effect of such landscape transitions on development of the urban heat island (UHI), but c ...
