Amorphous materials, although lacking the long-range translational and rotational order of crystalline and liquid crystalline materials, possess certain local (short-range) structure. This paper reviews the distribution of one particular component pr

Hexavalent chromium (Cr(VI)) and trivalent chromium (Cr(III)) are the primary chromium oxidation states found in ambient atmospheric particulate matter. While Cr(III) is relatively nontoxic, Cr(VI) is toxic and exposure to Cr(VI) may lead to cancer,

Hydrophobic aluminum nanoflake slurries were freeze dried using varying freezing conditions, aluminum concentrations, and shelf temperatures. The effectiveness of using cyclohexane as a carrier to produce dry, de-agglomerated aluminum powders was det

The 2 chromium oxidation states found in ambient atmospheric particulate matter (PM) are trivalent [Cr(III)] and hexavalent [Cr(VI)] chromium. Cr(III) is a trace element essential for the proper function of living organisms. However, Cr(VI) is toxic

Using a modified turbulent mixing CNC, the heterogeneous nucleation of different compounds (working fluids) on nanometer sized carbon particles was examined. The working fluids were dibutyl phthalate, octadecane, octadecanol, and octadecanoic acid. B

Freeze fracture‐electron microscopy (FF‐EM) was used to study the structure of the colloidal components present in Definity® and to determine changes that occur when the pharmaceutical is “activated” by shaking–a process by which the hydro

There is limited understanding of chromium chemistry in the atmosphere as well as after particles containing chromium are captured on filters during extended sampling intervals (24 h). Thus, experiments were conducted to investigate the role of ozone
