The mineralized shell changes the electric surface potential of the viruses. (sciencedaily.com)
These phases also exhibit different electric surface potentials determined by Kelvin probe force microscopy. (european-mrs.com)
Using a computer equipped with both a CPU and an AMD GPU, the Virginia Tech researchers were able to compute and visualize biomolecular electrostatic surface potential (pdf) 1,800 times faster (from 22.4 hours to less than a minute) than they could with a similar computer driven only by a CPU.
