DOI: 10.1016/j.scriptamat.2018.01.006
Abstract: Abstract Here, by using in situ transmission electron microcopy, we discovered a special mechanism governing the coarsening of intergranular helium bubbles, which exhibit pancake-like growth along grain boundaries to achieve coalescence with another bubble upon… read more here.

DOI: 10.1109/tdei.2019.008199
Abstract: Partial discharges (PD) in floating bubbles and in microspheres made from thin glass walls in transformer oil were studied experimentally and theoretically. In a test cell, the PD occurrence was a very rare event. Sometimes… read more here.

DOI: 10.13182/fst16-116
Abstract: The growth process of spherical helium bubbles located 6 nm below a (100) surface is studied using molecular dynamics and parallel replica dynamics simulations, over growth rates from 106 to 1012 helium atoms per second. Slower growth… read more here.
