Calculation of Relaxation Spectra from Stress Relaxation Measurements [PDF]

, 2010
Application of stress on materials increases the energy of the system. After removal of stress, macromolecules comprising the material shift towards equilibrium to minimize the total energy of the system.

Multi-scale shock-to-detonation simulation of pressed energetic material: A meso-informed ignition and growth model

Journal of Applied Physics, 2018
This work presents a multiscale modeling framework for predictive simulations of shock-to-detonation transition (SDT) in pressed energetic (HMX) materials. The macro-scale computations of SDT are performed using an ignition and growth (IG) model. However,

Molecular orientation-dependent energetic shifts in solution-processed non-fullerene acceptors and their impact on organic photovoltaic performance

Nature Communications, 2023
Non-fullerene acceptors with large quadrupole moments strongly affect thin-film energetics. Here, the authors show a significant energetic shift (>200 meV) of Y6 upon changing its orientation from face-on to more edge-on using different solvents and its ...

Can disorder enhance incoherent exciton diffusion? [PDF]

, 2015
Recent experiments aimed at probing the dynamics of excitons have revealed that semiconducting films composed of disordered molecular subunits, unlike expectations for their perfectly ordered counterparts, can exhibit a time-dependent diffusivity in ...

Forming a constant density medium close to long gamma-ray bursts [PDF]

, 2006
The progenitor stars of long Gamma-Ray Bursts (GRBs) are thought to be Wolf-Rayet stars, which generate a massive and energetic wind. Nevertheless, about 25 percent of all GRB afterglows light curves indicate a constant density medium close to the ...
