Experimental Research on an Afterburner System Fueled with Hydrogen–Methane Mixtures

Inventions
A new afterburner installation is proposed, fueled with pure hydrogen (100%H2) or hydrogen–methane mixtures (60% H2 + 40% CH4, 80% H2 + 20% CH4) for use in cogeneration applications.

Three-fluid Hydrodynamics-based Event Simulator Extended by UrQMD final State interactions (THESEUS) for FAIR-NICA-SPSBES/RHIC energies

EPJ Web of Conferences, 2018
We present a new event generator based on the three-fluid hydrodynamics (3FH) approach, followed by a particlization at the hydrodynamic decoupling surface and a subsequent UrQMD afterburner stage based on the microscopic UrQMD transport model that ...

Toward Sustainable Fiber‐Reinforced Polymer Composites

Macromolecular Materials and Engineering, Volume 309, Issue 9, September 2024.
Fiber‐reinforced polymer composites (FRPCs) are versatile materials used in transportation, construction, and electronics. As the composite market aims for 15.5 Mt by 2026, enhancing the sustainability of FRPCs is vital. Focus areas include end‐of‐life management, recyclability, the use of sustainable materials, and product simplification.

Obtaining high degree of circular polarization at x-ray free electron lasers via a reverse undulator taper

Physical Review Special Topics. Accelerators and Beams, 2013
Baseline design of a typical x-ray free electron laser (FEL) undulator assumes a planar configuration which results in a linear polarization of the FEL radiation. However, many experiments at x-ray FEL user facilities would profit from using a circularly
