Significant phase deviation of magnetic quantum oscillations induced by magnetic impurities
NPG Asia MaterialsMagnetic quantum oscillations, such as Shubnikov-de Haas oscillations or de Haas-van Alphen oscillations, are widely used tools for fermiology. Notably, the phase of magnetic quantum oscillations could inform about the symmetry or topology of materials ...

Advanced Engineering Materials, EarlyView.This work shows that the mechanical performance of multimaterial digital light processing (DLP) printed thermoset composites is governed by resin compatibility and interfacial design rather than spatial patterning alone. Brittle and ductile resin combinations produced premature interfacial failure, while graded interfaces and mechanically compatible ...

Advanced Functional Materials, EarlyView.Liquid‐phase transmission electron microscopy enables direct observation of nucleation and growth processes in solution. This review is dedicated to the remembrance of Helmut Cölfen and highlights recent studies on complex materials—oxides, biominerals, organic–inorganic crystals—which were central to his research activity. It summarizes key milestones,
