“…For example, this high-resolution characterization technique helps to understand diffusion of light element (e.g., boron and carbon), segregation at inter faces, gradients in chemical composition between second phase precipitate particles and their host matrix phase (Bang et al, 2015;Park et al, 2015;Seol et al, 2010Seol et al, , 2011Seol et al, , 2012Seol et al, , 2013aSeol et al, , 2013bSeol et al, , 2013cSeol et al, , 2016a. Recent significant advances of pulsedlaser APT system now enable analysis of biological material to obtain 3D spatial distributions of cellular ions (Gordon & Joester, 2011;Karlsson et al, 2015;Narayan et al, 2012).…”
