Seasonal measurements of total OH reactivity fluxes, total ozone loss rates and missing emissions from Norway spruce in 2011 [Discussion paper] [PDF]

, 2012
Numerous reactive volatile organic compounds (VOCs) are emitted into the atmosphere by vegetation. Most biogenic VOCs are highly reactive towards the atmosphere's most important oxidant, the hydroxyl (OH) radical.

From Waste to Catalyst: The Properties of Mixed Oxides Derived from Layered Double Hydroxide Mg/Al Synthesized from Aluminum Residues and Their Use in Transesterification

Reactions
Mixed oxides were obtained via calcination at 550 °C from layered double hydroxides (LDHs), which were synthesized in a previous study via co-precipitation and co-precipitation followed by hydrothermal treatment using aluminum residues as the source of ...

Ab Initio Molecular Dynamics Study of Methanol-Water Mixtures under External Electric Fields

Molecules, 2020
Intense electric fields applied on H-bonded systems are able to induce molecular dissociations, proton transfers, and complex chemical reactions. Nevertheless, the effects induced in heterogeneous molecular systems such as methanol-water mixtures are ...

Atomically Resolved Chemical Reactivity of Small Fe Clusters.

Physical Review Letters, 2020
Small metal clusters have been investigated for decades due to their beneficial catalytic activity. It was found that edges are most reactive and the number of catalytic events increases with the cluster's size.
