Measuring Aerosol Phase Changes and Hygroscopicity with a Microresonator Mass Sensor.
Arthur T Zielinski, Peter J Gallimore, Paul T Griffiths, Roderic L Jones, Ashwin A Seshia, Markus Kalberer

The interaction between atmospheric aerosol particles and water vapor influences aerosol size, phase, and composition, parameters which critically influence their impacts in the atmosphere. Methods to accurately measure aerosol...
Hydrolysis of organometallic and metal-amide precursors
The hydrolysis reaction between Brønsted basic organometallic or metal-amide reagents with Brønsted acidic OH groups from water or metal-hydroxides may act as a controlled stoichiometric strategy for the formation of M-O-M...
Palladium-catalysed C-H activation of aliphatic amines to give strained nitrogen heterocycles.
The development of new chemical transformations based on catalytic functionalization of unactivated C-H bonds has the potential to simplify the synthesis of complex molecules dramatically. Transition metal catalysis has emerged...
Enhanced Volatile Organic Compounds emissions and organic aerosol mass increase the oligomer content of atmospheric aerosols
I Kourtchev, C Giorio, A Manninen, E Wilson, B Mahon, J Aalto, M Kajos, D Venables, T Ruuskanen, J Levula, M Loponen, S Connors, N Harris, D Zhao, A Kiendler-Scharr, T Mentel, Y Rudich, M Hallquist, J-F Doussin, W Maenhaut, J Bäck, T Petäjä, J Wenger, M Kulmala, M Kalberer

The increasing threat to stratospheric ozone from dichloromethane.
Ryan Hossaini, Martyn P Chipperfield, Stephen A Montzka, Amber A Leeson, Sandip S Dhomse, John A Pyle

It is well established that anthropogenic chlorine-containing chemicals contribute to ozone layer depletion. The successful implementation of the Montreal Protocol has led to reductions in the atmospheric concentration of many...
A light-driven burst of hydroxyl radicals dominates oxidation chemistry in newly activated cloud droplets.
Suzanne E Paulson, Peter J Gallimore, Xiaobi M Kuang, Jie Rou Chen, Markus Kalberer, David H Gonzalez

Aerosol particles and their interactions with clouds are one of the most uncertain aspects of the climate system. Aerosol processing by clouds contributes to this uncertainty, altering size distributions, chemical composition...
Stratospheric Ozone destruction by the Bronze-Age Minoan eruption (Santorini Volcano, Greece).
The role of volcanogenic halogen-bearing (i.e. chlorine and bromine) compounds in stratospheric ozone chemistry and climate forcing is poorly constrained. While the 1991 eruption of Pinatubo resulted in stratospheric ozone loss...
