4D reconstruction of alumina laser melt pools at 25 kHz via operando X-ray multi-projection imaging
Lars Witte, Eliot Jermann, Zhe Hu +9
Advancing additive manufacturing, e.g., laser powder-bed fusion (LPBF), requires resolving rapid processes such as melt-pool dynamics and keyhole evolution in 4D (3D + time). Opera…

Time-resolved X-ray radiography of through-thickness liquid transport in partly saturated needle-punched nonwovens
Patrick Wegele, Zisheng Yao, Jonas Tejbo +7
Nonwoven fibre networks underpin filtration, insulation and geotextiles, where liquid uptake, redistribution and release govern performance. In needle-punched felts, barbed needles…
