We present an instrument that addresses two critical requirements for quantitative measurements of the homogeneous crystal nucleation rate in supersaturated aqueous solution. First, the need to perform repeated measurements of nucleation incubation times is met by automating experiments to enable programmable cycling of thermodynamic conditions. Second, the need for precise and robust control o...

In this article, optimization of a black box using designs of experiments is studied. There are two fundamental different branches in optimization using Design of Experiments; higher order Taylor expansions, i.e., response surface methodology, and underdetermined experimental designs, i.e., supersaturated designs. In this article, supersaturated designs are studied. Optimization using design of...

The classical nucleation theory for homogeneous nucleation is formulated as a theory for a density fluctuation in a supersaturated gas at a given temperature. But Molecular Dynamics simulations reveal that it is small cold clusters which initiates the nucleation. The temperature in the nucleating clusters fluctuate, but the mean temperature remains below the temperature in the supersaturated ga...

The 2-D version of the non-hydrostatic fully compressible model MOLOCH developed at ISAC-CNR was used in idealized set-up to study the start-up and finite amplitude evolution of symmetric instability. The unstable basic state was designed by numerical integration of the equation which defines saturated equivalent potential vorticity q e . We present the structure and growth rates of the linear ...

We report an extensive airborne characterization of aerosol downwind of a massive bovine source in the San Joaquin Valley (California) on two flights during July 2007. The Center for Interdisciplinary Remotely-Piloted Aircraft Studies (CIRPAS) Twin Otter probed chemical composition, particle size distribution, mixing state, suband supersaturated water uptake behavior, light scattering propertie...

Amorphous solid dispersions are of great current interest because they can improve the delivery of poorly water-soluble compounds. It has been recently noted that the highly supersaturated solutions generated by dissolution of some ASDs can undergo a phase transition to a colloidal, disordered, drug-rich phase when the concentration exceeds the "amorphous solubility" of the drug. The purpose of...

The solid state dewetting (SSD) of metallic bilayers is a straightforward method for the fabrication alloy nanoparticles. In particular, alloys that present gap miscibility offer rich phenomenology regarding not only particle formation but also composition their phases. work, AuNi precursor have been annealed at different temperatures and times to produce evolution shape, size, interparticle di...
