Mach (top) and pressure (bottom) contours for axisymmetric Busemann inlet with evenly spaced bleed perforations along length of inlet. Images show changes in Mach and pressure contours as a function of inlet length ranging from inlet start (left) and inlet throat (right). Contours were produced via Cart 3D, an inviscid code for automated CFD.
These images of rat alveolar macrophages exposed to FITC doped silica nanoparticles were captured in a series through the z-plane using a laser scanning confocal microscope (Olympus). The fluorescent silica particles are packaged into phagosomes, which are distributed throughout the cell, showing that the macrophage is reaching capacity. At a certain concentration, the capacity of the macrophages to ingest particles will be overwhelmed, and their ability to remove foreign matter from the airways will be compromised.
These are the images of poly-amide crystals grown from solution. Crystals are seen under optical microscope (lower resolution) and Scanning electron Microscope (Higher resolution). These images are an artistic capture of polymer crystals which conveys the message: “nature loves symmetry and beauty”.
This image was captured using a hyperspectral microscope (CytoViva, Auburn, AL). The different scattered colors provide information about the size and shape of the nanoparticles, and it has been shown that blue, green, yellow, and red correlate with sphere, pentagon, rounded-triangle, and triangle shaped particles, respectively (Mock et al., 2002). This data can be stored in a software program to later identify silver nanoparticles with specific properties within more complex environments, such as cells.
