Mechanical properties and energy–absorption capabilities of thermoplastic sheet gyroid structures
Mechanics of Advanced Materials and Structures, 2021 The development of additive manufacturing and lattice structures has created opportunities for the development of lightweight impact–absorption structures that can overcome most constraints of previously used materials such as expanded polystyrene foams.

Radio Emission and Particle Acceleration in SN 1993J [PDF]
, 1998 The radio light curves of SN 1993J are found to be well fit by a synchrotron spectrum, suppressed by external free-free absorption and synchrotron self-absorption. A standard r^-2 circumstellar medium is assumed, and found to be adequate.

Architected lattices with adaptive energy absorption [PDF]
Extreme Mechanics Letters, 2019 Energy absorbing materials, like foams used in protective equipment, are able to undergo large deformations under low stresses, reducing the incoming stress wave below an injury or damage threshold. They are typically effective in absorbing energy through plastic deformation or fragmentation.

Energy absorption in the laser-QED regime
Scientific Reports, 2019 A theoretical and numerical investigation of non-ponderomotive absorption at laser intensities relevant to quantum electrodynamics is presented. It is predicted that there is a regime change in the dependence of fast electron energy on incident laser ...

Numerical and experimental studies on compressive behavior of Gyroid lattice cylindrical shells
Materials & Design, 2020 In this paper, Gyroid lattice cylindrical shell (LCS) specimens were designed by a newly proposed mapping methodology and were fabricated by selective laser melting (SLM) technology. Their energy absorption and deformation modes were investigated through

Detailed X-ray spectroscopy of the magnetar 1E 2259+586 [PDF]
, 2019 Magnetic field geometry is expected to play a fundamental role in magnetar activity. The discovery of a phase-variable absorption feature in the X-ray spectrum of SGR 0418+5729, interpreted as cyclotron resonant scattering, suggests the presence of very ...

Encapsulated OSB Energy Absorption Potential
Brazilian Journal of Radiation Sciences, 2022 The transport of radioactive substances is, in many ways, necessary in the context of the nuclear fuel cycle that aims to generate energy or radioisotopes. In the event of a possible accident, the shock-absorbing parts reduce the mechanical stresses on the other components of the transport packaging, since a large part of the kinetic energy is absorbed
