Energy loss of keV He^2+ scattered off an A1(110) surface

open access: yes, 1998
This paper presents results of measurements of energy loss suffered by He-projectiles scattered off an Al surface. The measured loss distributions are modeled in terms of the (classical) friction experienced by the projectiles due to their interaction ...

Exploring Sustainable Growth: Eco‐Innovation Among Small and Medium‐Sized Enterprises

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT We examined how small and medium‐sized enterprises (SMEs) in the aerospace industry developed capabilities for eco‐innovation, specifically SMEs enrolled in a green transition mentorship programme. To this end, we conducted multiple case studies over 2 years (August 2022 to November 2024) to gather data through semi‐structured interviews with ...

Production of He-3 and He-6 fragments in the interaction of C-12 with Nb-93 at 400 MeV

open access: yes, 2005
Spectra of inclusive double differential cross sections of He-3 and He-6 fragments produced in the interaction of C-12 with Nb-93 at 400 MeV are measured and analyzed.

Plasmakristall‐4 Experiment: 10 Years of Operation in Orbit

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Plasmakristall‐4 (PK‐4) is a microgravity complex plasma laboratory operated for 10 years on board the International Space Station. Its main purpose is the particle‐resolved investigation of generic condensed matter phenomena using strongly coupled suspensions of microparticles immersed in low‐pressure gas‐discharge plasmas.

Electronic stopping power of H and He in Al and LiF from first principles

open access: yes, 2013
Non-linearities in the electronic stopping power of light projectiles in bulk Al and LiF are addressed from first principles using time-evolving time-dependent density functional theory.

Stopping Power of Electron Liquid for Slow Quantum Projectiles

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT We revisit the problem of the deceleration of a charge moving in a medium. In the low‐velocity limit of the projectile, we construct the fully nonlinear (in the charge–target interaction) theory of the stopping power (SP), which goes beyond the classical Ehrenfest dynamics.

Enhanced excitation of giant pairing vibrations in heavy-ion reactions induced by weakly bound projectiles

open access: yes, 2002
The use of radioactive ion beams is shown to offer the possibility to study collective pairing states at high excitation energy, which are not usually accessible with stable projectiles because of large energy mismatch.

Modelling the formation of explosively formed projectiles (EFP) [PDF]

open access: yes, 2016
The number of victims of attacks from improvised explosive devices (IED), especially from roadside bombs where explosively formed projectiles (EFP) are frequently used, has steeply increased until 2011. Understanding these threats, how they are built and

Fish Scales: A Multifunctional Biomaterial from Nature

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...
