Előadásának címe:
 
***        GASPHASE SYNTHESIS AND CHARACTERIZATION OF 
            AEROSOL NANOPARTICLES BY LOW PRESSURE IMPACTION
 
Rövid kivonata:
 
At high concentrations gasborne nanoparticles tend to form agglomerates.
This agglomeration may reduce many of the beneficial nanoparticle
properties such as bioavailability and optical behavior. Therefore,
techniques are needed to avoid agglomeration in an early stage of
particle formation or to fragmentate already formed agglomerates. In
this talk, strategies will be shown to follow these two lines. On the
one hand, organic nanoparticles which are formed by Rapid Expansion of
Supercritical Solution can be stabilized as nanosuspension. On the other
hand, low pressure jets can be used to desintergrate agglomerates by
impaction. In addition, this method provides the possibility to measure
the influence of surface modifications on the interparticle bond
strength.
