Dual effect of humidity on cesium lead bromide: enhancement and degradation of perovskite films

Michael Graetzel, Mohammad Ibrahim Dar, Simone Meloni

CsPbBr3 perovskite is highly desired to fabricate many optoelectronic devices: high photovoltage solar cells, tandem solar cells, light-emitting diodes, lasers, photodetectors, field effect transistors etc. However, to realize these applications, resistanc ...

On the implications of aerosol liquid water and phase separation for organic aerosol mass

Athanasios Nenes, Hairun Guo

Organic compounds and liquid water are major aerosol constituents in the southeast United States (SE US). Water associated with inorganic constituents (inorganic water) can contribute to the partitioning medium for organic aerosol when relative humidities ...

Copernicus GmbH2017

We present the In situ/Remote sensing aerosol Retrieval Algorithm (IRRA) that combines airborne in situ and lidar remote sensing data to retrieve vertical profiles of ambient aerosol optical, microphysical and hygroscopic properties, employing the ISORROPI ...

Copernicus GmbH2017

Particle water (liquid water content, LWC) and aerosol pH are important parameters of the aerosol phase, affecting heterogeneous chemistry and bioavailability of nutrients that profoundly impact cloud formation, atmospheric composition, and atmospheric flu ...

Copernicus GmbH2016

Secondary aerosols formed from anthropogenic pollutants and natural emissions have substantial impacts on human health, air quality, and the Earth’s climate. New particle formation (NPF) contributes up to 70% of the global production of cloud condensation ...

Wiley-Blackwell2016

Particle pH is a critical but poorly constrained quantity that affects many aerosol processes and properties, including aerosol composition, concentrations, and toxicity. We assess PM1 pH as a function of geographical location and altitude, focusing on the ...

Aerosol water parameterisation: A single parameter framework

Athanasios Nenes

We introduce a framework to efficiently parameterise the aerosol water uptake for mixtures of semi-volatile and non-volatile compounds, based on the coefficient, vi. This solute-specific coefficient was introduced in Metzger et al. (2012) to accurately par ...

Real-Time, Online Automated System for Measurement of Water-Soluble Reactive Phosphate Ions in Atmospheric Particles

Athanasios Nenes, Kalliopi Violaki

We present a novel automated system for real-time measurements of water-soluble reactive phosphate (SRP) ions in atmospheric particles. Detection of SRP is based on molybdenum blue chemistry with Sn(II) chloride dihydrate reduction. The instrumentation con ...

Fine-particle water and pH in the southeastern United States

Athanasios Nenes, Hairun Guo

Particle water and pH are predicted using meteorological observations (relative humidity (RH), temperature (T)), gas/particle composition, and thermodynamic modeling (ISORROPIA-II). A comprehensive uncertainty analysis is included, and the model is validat ...
