      abstract     = {In the present study, time-resolved aerosol particle
                      formation from sulfuric acid vapor is examined with special
                      attention to the stabilization of molecular clusters in the
                      early phase of unary nucleation. An important factor
                      governing this process is the amount of condensable acid
                      vapor. Here it is produced from fast gas-phase reactions in
                      a batch-type reaction cell for which we introduce
                      modifications enabling real-time monitoring. The key
                      component for size- and time-resolved detection of ultrafine
                      particles is a new 1 nm-SMPS. With this new tool at hand,
                      the effect of varying the precursor concentration over two
                      orders of magnitude is investigated. We demonstrate the
                      ability to tune between different growth scenarios as
                      indicated by the size-resolved particle traces which exhibit
                      a transition from sigmoidal over quasi-stationary to
                      peak-like shape. The second key parameter relevant for
                      nucleation studies is the temperature-dependent cluster
                      evaporation. Due to a temperature rise during the mixing
                      stage of the experiment, evaporation is strongly promoted in
                      the early phase. Therefore, the present study extends the
                      T-range used in, e.g., smog chambers. We investigate this
                      temperature effect in a kinetic simulation and can
                      successfully combine simulated and measured data for
                      validating theoretical evaporation rates obtained from
                      DLPNO-CCSD(T0)-calculations.},
