Palladium Supercrystals

SEM image of supercrystals formed by palladium nano-cuboctahedron monomers. These crystals are formed by the self-assembly of the monomers due to the slow diffusion of surfactant (cetrimonium chloride) into a concentrated colloidal solution of palladium nano-cuboctahedron.The supercrystals formed are highly dependent on the shape of the monomer nanoparticle used.

Beauty in the Curve

Curved aspirin crystallites are observed in this cross polarized optical micrograph. The curvature in the crystallites is observed when a two-step mechanism of solution deposition and subsequent spherulite growth occurs during solution printing on an SiO2 wafer.

COMPASS: Navigating the Protein Landscape

NMR spectroscopy is a powerful technique for determining protein structures that traditionally requires months of data analysis. COMPASS replaces manual data analysis with a computer vision-inspired algorithm that identifies the unique structure using a single spectrum. This artistic representation depicts COMPASS revealing the correct fold in the dark structural landscape.

Imperfect intruder  

An immature retrovirus has a near-spherical capsid with plenty of structural defects and is therefore non-infectious. The blood cells at the background illustrate the viruses (blue dots) successful entered the cells but failed to hijack the cell’s machinery. The figure of the retrovirus was produced using VMD (Visual Molecular Dynamics).
