WebTaking advantage of the last cryogenic electron microscopy structure of human huntingtin, we explored with computational methods its physicochemical properties, focusing on the solvent accessible surface of the protein and highlighting a quite interesting mix of hydrophobic and hydrophilic patterns, with the prevalence of the latter ones. We then … Web9.1 Ion Stopping As each implanted ion impinges onto the target, it undergoes a series of collisions with the host atoms until it finally stops at some depth, as depicted in Figure 9.1. Since the initial ion energy, typically several tens of keV, is much higher than lattice binding energies, the ion scattering process can be simulated based on
