Mechanoluminescence (ML) is a type of luminescence induced by any mechanical action on
solids. The light emissions induced by elastic deformation, plastic deformation and fracture …

Abstract Development of the deformation monitoring techniques for the infrastructures so as
to avoid catastrophic failure and resulting economic/human loss has remained a key interest …

Visualization of stress distribution has been realized by a nondestructive
mechanoluminescence (ML) from SrAl2O4: Eu, which can emit three magnitudes higher …

Smart materials--materials and structures that can impart information about their
environment to an observer or monitoring device--are revolutionizing fields as diverse as …

Elastico-deformation luminescence in strontium aluminates was investigated systematically
using precisely controlled pure-phase Eu-doped strontium aluminates of SrAl12O19 …

Although ashfall from particulate volcanic plumes is known to be highly electrically charged,
little is known about the charging mechanism. We describe experiments designed to …

Fracture in disordered media is a complex problem for which a definitive physical and
theoretical treatment is still lacking. We view earthquakes (EQ's) as large-scale fracture …

Surface energies of silicates influence crack propagation during brittle fracture and decrease
with surface relaxation caused by annealing and hydroxylation. Molecular-level simulations …

Abstract Two new compounds, Sr 3 (Sn 2-x Si x) O 7: Sm 3+ and Sr 3 (Sn 2-x Ge x) O 7: Sm
3+, were synthesized by a solid-state reaction method and their structure, optical bandgap …

A large number of noncentric and centric organic and inorganic crystals exhibit intrinsic and
extrinsic fracto-mechanoluminescence (ML) due to the electron bombardment and electron …
