Abstract: Herein, in-situ high pressure Raman spectra of 7,7,8,8-tetracyanoquinodimethane (TCNQ) have been measured up to 10 GPa, and a first-order phase transition was detected at about 2.3 GPa. An anharmonic coupling (Fermi resonance) between fundamental modes was observed.… read more here.

Abstract: Abstract The determination of non-fundamental modes of the diffusion equation is required for computing CANDU reactor power distribution from analysis of in-core detector readings. They are also important for understanding subcritical mode instabilities occurring in… read more here.

DOI: 10.1177/0954406217698721
Abstract: A quasi-isotropic composite laminate is constructed in an attempt to create a structure that behaves like an isotropic plate. Its membrane behavior is similar to that of the isotropic plate while the bending behavior is… read more here.
