“…This assumption is justified by the results of neutron scattering experiments performed on zinc foams. [27] The existence of an initial porosity with a pore size in the order of magnitude of the residual porosity after compaction observed in this study is reported. Furthermore, it is reported that this porosity completely disappears in the foaming process during the early stages of pore formation, at %10 pct porosity.…”

“…Ultrasmall-angle neutron scattering (USANS) can measure the pore size distribution as an average over the entire sample. 8 And scanning electron microscopy can probe individual pores within the sample.…”

“…The graph shows the pore size distributions measured by ultrasmall-angle neutron scattering (USANS) at various times after the foaming started. 8 colleagues at the Light Metal Competence Center (LKR) and Hütte Kleinreichenbach (HKB), both located in Austria, have found a new way to produce extremely uniform aluminum foam structures stabilized with ceramic particles. The trick is a novel bubble generation device that allows the creation of nearly uniform-sized bubbles.…”

“…Existen varios estudios de caracterización del proceso de espumación realizados mediante el uso de avanzadas técnicas, tales como monitoreo de imáge-nes a diferentes tiempos de espumación [70] , tomografía de RX [71][72][73] , microtomografia de alta resolución [74][75][76] , por microgravedad [77][78][79][80][81] radioscopia de RX [82] , barrido de neutrones de ángulo pequeño [83][84][85] , XRD [86] , entre otros. Brunke y Odenbach, por su parte, realizaron experimentos encaminados a demostrar la influencia de las fuerzas de Lorentz y las fuerzas rotacionales en el comportamiento de las espumas líqui-das [87] .…”
