This work deals with the evolution of mesoporous structure two silicas MCM-41 and SBA-15 under a 2 MeV electron beam as function dose (0–5 GGy). For GGy, pore volume materials decreases significantly by 40–45%. The irradiation-induced porosity closure is more effective on smaller pores, resulting in loss network concerning (pore diameter ∼ 3.8 nm) conservation one 7.0 nm). mechanism silica clos...

Technological advancement towards the quantum era requires secure communication, computation and ultra-sensitive sensing capabilities. Layered materials (LQMs) have remarkable optoelectronic properties that can usher us into era. Electron microscopy is tool of choice for measuring these LQMs at an atomic nanometre scale. On other hand, electron-irradiation modify various material properties, in...
