It has long been hypothesized that acids formed from anthropogenic pollutants and natural emissions dissolve iron (Fe) in airborne particles, enhancing the supply of bioavailable Fe to the oceans. However, field observations have yet to provide indisputable evidence to confirm this hypothesis. Single-particle chemical analysis for hundreds of individual atmospheric particles collected over the ...
Tightening legislation on the emission of hazardous pollutants is driving chemical industries towards the implementation of innovative “clean technology” including the use of alternative heterogeneously catalyzed processes. This prompted us to examine the catalytic potential of Indian clays for fine chemical synthesis. Catalytic activity of clay minerals from India was only less studied. In the...
