TL;DR: In this article, the authors investigate the molecular influence on dynamic impedance using microballistic measurements on two bulk elastomers, a PUU and a polyurea, PU, and calculate the shock impedance from the shock velocity data derived from the respective shock Hugoniot to determine the efficacy of dynamic impedance optimization between PUUs and glass.

TL;DR: In this paper, a single-shot femtosecond spectroscopy technique was proposed for real-time examination of irreversible decomposition in energetic solids using two crossed echelon optics.

TL;DR: It is shown that a pulsed THz electric field, enhanced by a microslit field enhancement structure (FES), can strongly manipulate the optical absorption properties of a thin film of CdSe andCdSe:CdS core:shell QDs on the sub-picosecond timescale, with spectral shifts that span the visible to near-IR range.

TL;DR: In this paper, the phonon Boltzmann transport equation (BTE) is used to study non-diffusive thermal transport in thin-film transient thermal grating (TTG) experimental geometry.

TL;DR: In this article, a new universal variational approach was developed to solve the phonon Boltzmann transport equation (BTE) that enables extraction of phonon mean free path (MFP) distributions from experiments exploring nondiffusive transport.
