The Semi-Hooperon: Gamma-ray and anti-proton excesses in the Galactic Center

open access: yes, 2017
A puzzling excess in gamma-rays at GeV energies has been observed in the center of our galaxy using Fermi-LAT data. Its origin is still unknown, but it is well fitted by Weakly Interacting Massive Particles (WIMPs) annihilations into quarks with a cross ...

Evaluation of Surface Quality in SLS‐Printed Nylon 12 Parts for Hygienic Applications in the Food Industry

open access: yesJournal of Applied Polymer Science, EarlyView.
SLS‐printed PA12 specimens (untreated or VaporFuse Surface–treated) were evaluated by PAA sanitization (400 ppm; L. monocytogenes, E. coli, S. aureus) and ISO 3452–based penetrant testing, showing > 99.999% bacterial reduction on both surfaces and improved surface continuity after VFS.

Propagation of high-energy cosmic rays in extragalactic turbulent magnetic fields: resulting energy spectrum and composition

open access: yes, 2007
We extend previous studies of mixed-composition extragalactic cosmic-ray source models, by investigating the influence of a non-negligible extragalactic magnetic field on the propagated cosmic-ray spectrum and composition.

Scalable desolvation synthesis, storage stability, and comprehensive biophysical characterization of human hemoglobin nanoparticles as a potential hemoglobin‐based oxygen carrier

open access: yesBiotechnology Progress, EarlyView.
This work describes the development of human hemoglobin nanoparticles using an anti‐solvent precipitation synthesis method as a potential next generation hemoglobin‐based oxygen carrier. The hemoglobin nanoparticles are uniform in size and shape, hemocompatible, stable at various storage conditions, and demonstrate a scalable synthesis technique ...

Resource‐Efficient Electrodes with Metallized Woven‐Glass‐Grid Current Collectors for Lithium‐Ion Batteries

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
The use of metallized glass‐based woven‐grids instead of metal foils as current collectors for LIBs leads to a significant reduction in metal usage by over 90 % and weight savings of more than 80 %, resulting in an 11 % increase in specific energy at the cell level. Abstract A novel class of resource‐efficient, woven‐glass‐grid current collectors (CCs)
