DOI: 10.1002/2017gl075298
Abstract: Whether or not background secondary craters dominate populations of small impact craters on terrestrial bodies is a half-century controversy. It has been suggested that small craters on some planetary bodies are dominated by background secondary… read more here.

DOI: 10.1002/2017gl075572
Abstract: Many volcanoes around the world host summit crater lakes but their influence on the overall stability of the edifice remains poorly understood. Here I use satellite radar data acquired by TerraSAR-X from early 2015 to… read more here.

DOI: 10.1007/s00445-017-1132-x
Abstract: On 5 July 2014, an eruptive fissure opened on the eastern flank of Etna volcano (Italy) at ~3.000 m a.s.l. Strombolian activity and lava effusion occurred simultaneously at two neighbouring vents. In the following weeks, eruptive… read more here.

DOI: 10.1007/s11663-017-0986-9
Abstract: Recent reports have demonstrated the possibility of mitigating macrosegregation during the Direct-Chill casting of rolling slab ingots using an impinging jet. Herein, an analytical model is presented to predict the shape of the crater formed… read more here.

DOI: 10.1016/j.apsusc.2019.07.024
Abstract: Abstract Irradiation of the heterostructure glass/Ta/Pt/GdFeCo/IrMn/Pt by 50 fs ultra-short laser pulses causes local thinning of the film down to ~12–30 nm depth. These pits are distinguished by Atomic Force Microscopy (AFM), while their stray magnetic fields… read more here.
