Extrudability of geopolymers and control of the formed networks by zeta potential and NMR spectroscopy

open access: yesInternational Journal of Ceramic Engineering &Science, Volume 7, Issue 1, January 2025.
Evolution of the various parameters controlling the geopolymer extrudability. Abstract In this study, the local‐scale structure of geopolymers shaped by extrusion or 3D printing was investigated and correlated to the reactivity of the raw materials. The reactivity of the different metakaolin mixtures was evaluated using zeta potential measurements with

Extrem neutronenreicher Sauerstoffkern

open access: yesPhysik in unserer Zeit, Volume 56, Issue 1, Page 38-44, January 2025.
Die Sauerstoffatome in unserer Luft haben fast immer acht Protonen und acht Neutronen. Unter extremen Bedingungen, wie in Neutronensternen, kann aber Sauerstoff mit bis zu 16 Neutronen existieren. Einem internationalen Forschungsteam ist es gelungen, den neutronenreichsten Sauerstoffkern 28O mit sogar 20 Neutronen an der Forschungsanlage RIKEN in Japan
