Proton transfer in histidine-tryptophan heterodimers embedded in helium droplets

open access: yes, 2015
We used cold helium droplets as nano-scale reactors to form and ionize, by electron bombardment and charge transfer, aromatic amino acid heterodimers of histidine with tryptophan, methyl-tryptophan, and indole. The molecular interaction occurring through

Failure Mechanisms of Short Fiber Reinforced Composite Materials Subjected to Dynamic Loading

open access: yesPolymer Composites, Volume 47, Issue 9, Page 8273-8287, 10 May 2026.
Failure Mechanisms of Short Fiber Reinforced Composite Materials Subjected to Dynamic Loading. ABSTRACT The mechanical behavior of short carbon fiber reinforced polylactic acid (SCF/PLA) composites fabricated by fused deposition modeling (FDM) is crucial for engineering applications, yet their strain‐rate dependence is not fully understood.

Mechanical behavior of sand under high pressure and high strain rate

open access: yesEPJ Web of Conferences, 2012
Characterizing of the mechanical behavior of sand under impact loading is necessary to estimate the power of explosive mines. Using Hopkinson pressure bars for its characterization only low and limited pressures can be applied.

Compressive behaviour of dam concrete at higher strain rates [PDF]

open access: yes, 2014
The mechanical behaviour of concrete when subjected to impact or blast has still many aspects requiring further study. Dam concrete is characterized by large coarse aggregates, hence large specimen sizes are needed in order to study a representative ...

Mapping Nanoscale Buckling in Atomically Thin Cr2Ge2Te6

open access: yesAdvanced Functional Materials, Volume 36, Issue 36, 4 May 2026.
Atomic‐resolution STEM is used to resolve nanoscale buckling in monolayer Cr2Ge2Te₆. A noise‐robust image analysis reconstructs three‐dimensional lattice distortions from single plan‐view images, revealing pronounced defect‐driven nm‐scale out‐of‐plane buckling.

Recent developments in dynamic testing of materials

open access: yesEPJ Web of Conferences, 2012
Three new testing configurations that have been developed since the last DYMAT conference in 2009 are presented. The first is high strain rate testing of Kevlar cloth and Kevlar yarn in a tensile Split Hopkinson Bar (SHB) apparatus. The Kevlar cloth/yarn

Effect of the contact geometry on high strain rate behavior of woven graphite/epoxy composites [PDF]

open access: yes, 2011
Effects of the loading direction on high strain rate behavior of cylindrical woven graphite/epoxy composites are presented. Compressive split Hopkinson pressure bar (SHPB) was used for high strain rate experiments.

Superior Impact‐Resistant Composite Hydrogels Through an Ionic Coupling Strategy

open access: yesAdvanced Materials, Volume 38, Issue 26, 8 May 2026.
An ionic coupling strategy is developed to simultaneously reinforce networks and interfaces in composite hydrogels. Sodium citrate acts as a single multifunctional ionic coupler to strengthen the poly(vinyl alcohol) matrix via the Hofmeister effect, reinforce the chitosan–sodium alginate nanofiber network via desolvation and electrostatic crosslinking,
