(Carter et al. 2010b, 2010a). 73 Recently, a metallic alloy with composition Mn72.3Si15.6Cr9.7Al1.8Ni0.6, found in a fulgurite from 74 Nebraska, was shown to be a dodecagonal quasicrystal (Bindi et al. 2023a). The origin of this 75 fulgurite is not clear, since it was recovered after a storm at the site...

Modeling suggests that the relatively small volume changes observed for Na + -smectite are attributable to a reduction of interparticle void volume as expanding quasicrystals encroach into surrounding larger-scale pores. Volume change hysteresis is attributed to unrecovered alterations in interparticle...
