We study the wear rate (mass loss per unit sliding distance) of a tire tread rubber compound sliding on concrete paver surfaces under dryand wet conditions, at different nominal contact pressures of σ0 = 0.12, 0.29, and 0.43 MPa, and sliding velocities ranging from v = 1 μm s−1to 1 cm s−1. We find that the wear rate is proportional to the normal force and remains independent of the sliding speed [...]

This thesis examines proton-induced radiation damage and sustainability of vanadium and copper-based target materials for High Current Accelerator-driven Neutron Source (HiCANS) applications, especially in the context of the High-Brilliance neutron Source (HBS) project at Forschungszentrum Jülich. Vanadium has been evaluated for 20 MeV proton irradiation target and copper is assessed for 3 MeV proton irradiation target or backing. [...]

Ozone (O3) is an internationally regulated air pollutant that damages human health, vegetation, and the climate, yet remains one of the most challenging atmospheric constituents to predict. Tropospheric ozone is driven by complex, nonlinear interactions between precursor emissions, meteorology, and chemistry across scales. [...]
