On 20 July 2026, we threw a farewell gathering at Smokehouse Bar & Grill for Ephrem. He has been with us for 7 years, contributing a lot of research output in our group. Wish you all the best!

The acid displacement reaction of formic acid in sea-salt aerosols to release hydrogen chloride is an enigma in atmospheric chemistry: a weak acid transfers a proton to the conjugate base of a strong acid, reversing solution-phase acid–base chemistry. We show that a surface defect of the crystal lattice Na13Cl12+

We explored the gas-phase ion chemistry of hydrated electron in the reaction with a prototypical organosulphur compounds, i.e. dimethyl disulphide. We showed that the overall reaction is gated by a critical S···H hydrogen bond, which enables a kinetically challenging electron transfer step. The overall exothermicity is not driven

Having some alcohol to celebrate Zachary for successful PhD defence!
