Integrating Al with NiO nano honeycomb to realize an energetic material on silicon substrate [PDF]

open access: yes, 2009
Nano energetic materials offer improved performance in energy release, ignition, and mechanical properties compared to their bulk or micro counterparts. In this study, the authors propose an approach to synthesize an Al/NiO based nano energetic material ...

Opportunistic use of a wool-like artificial material as lining of Tit (Paridae) nests [PDF]

open access: yes, 2012
The lining material is a key element of bird nests primarily serving as insulation for the adult, eggs and/or chicks but collection of such material will have an energetic cost.

Beam-Induced Damage Mechanisms and their Calculation [PDF]

open access: yes, 2016
The rapid interaction of highly energetic particle beams with matter induces dynamic responses in the impacted component. If the beam pulse is sufficiently intense, extreme conditions can be reached, such as very high pressures, changes of material ...

Calculation of Relaxation Spectra from Stress Relaxation Measurements [PDF]

open access: yes, 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.

Can disorder enhance incoherent exciton diffusion? [PDF]

open access: yes, 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]

open access: yes, 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 ...

Coordination Energetic Materials—Scientific Curiosity or Future of Energetic Material Applications?

open access: yesApplied Sciences, 2022
Significant incentives for developing and introducing new energetic materials to the industrial-scale production and application of new energetic materials have stimulated extensive research on the subject. Despite numerous studies, which have reported a broad array of results, progress in this field remains limited as the research results do not ...

The origin of defects induced in ultra-pure germanium by Electron Beam Deposition [PDF]

open access: yes, 2015
The creation of point defects in the crystal lattices of various semiconductors by subthreshold events has been reported on by a number of groups. These observations have been made in great detail using sensitive electrical techniques but there is still ...

Galactic Cosmic Rays from Superbubbles and the Abundances of Lithium, Beryllium, and Boron [PDF]

open access: yes, 2002
In this article we study the galactic evolution of the LiBeB elements within the framework of a detailed model of the chemical evolution of the Galaxy that includes galactic cosmic ray nucleosynthesis by particles accelerated in superbubbles.
