The low temperature aerosol chamber AIDA was used to study the nucleation of nitric acid dihydrate (NAD) in super-cooled nitric acid aerosols under simulated stratospheric conditions in the temperature range 192 K–197 K. The nucleating solution dro

Activation energies ΔGact for the nucleation of nitric acid dihydrate (NAD) in supercooled binary HNO3/H2O solution droplets were calculated from volume-based nucleation rate measurements using the AIDA (Aerosol, Interactions, and Dynamics in the At

The EU-project MINATROC (MINeral dust And TROpospheric Chemistry) aims at enabling an estimation of the influence of mineral dust, a major, but to date largely ignored component of tropospheric aerosol, on tropospheric oxidant cycles. Within the scop

Complex refractive indices for supercooled sulfuric acid solution droplets in the mid-infrared spectral regime (wavenumber range 6000-800 cm -1 ) have been retrieved for acid concentrations ranging from 33 to 10 wt % H 2 SO 4 at temperatures between

The conditioning of aerosol particles to a predefined composition and size can be considered as a standard problem in aerosol technology. Quite often aerosols generated by dispersing diluted solutions are conditioned in a subsequent flow reactor.To m

Within the European Safety and Environmental Assessment of Fusion Power (SEAFP), off-site public doses were assessed for representative hypothetical worst case fusion power station accident sequences driven by in-plant energies, without taking credit

We report on a 78-year-old female patient, who presented to the emergency department with nausea and vomiting.Endoscopy of the upper gastrointestinal tract revealed gastric erosions and duodenal ulcers. The patient had iron deficiency anemia.Followin

The computer code NACHE is designed to describe the physical and chemical behaviour of polydisperse aerosol systems. To simulate such processes in a realistic way the influence of mixtures of different electrolytes on e.g. the uptake of water has to

An extended version of the aerosol code PARDISEKO is used to study the dynamics of solid fractal particles. Compared to compact ones, they show slower sedimentation and much enhanced coagulation rates. Most important, however, is the dramatically inc

The PODA-2 (Piloting ODA-2) Project is an ESPRIT-funded collaboration involving most of the leading IT companies in Europe. This paper describes the ways in which the Project is promoting and advancing the ODA standard and how the results of the work
