Green biomass as a sustainable source of protein
The food industry is increasingly focusing on sustainable products. Proteins from green biomass are a promising option, as a research team involving the MLZ has discovered. These can be used, for example, as stabilisers in emulsions, such as in plant-based alternatives to yogurt, milk, ice cream, or cheese.
Oxygen-isotope effect on the density wave transitions in La3Ni2O7
The isotope effect is a powerful probe of electron-phonon interactions in solid-state systems, offering key insights into how atomic mass influences emergent quantum states. Here, the impact of oxygen-isotope substitution (16O→18O) on charge- and spin-density wave (CDW and SDW) transitions in the double-layer Ruddlesden-Popper nickelate La3Ni2O7 is investigated ...
Pressure and oxygen-isotope substitution on density-wave transitions in La4Ni3O10
Understanding the interplay between magnetism and superconductivity in nickelate systems is a key objective in condensed matter physics. Gaining microscopic insights into magnetism—particularly as it emerges near superconductivity—requires a synergistic approach that combines complementary experimental techniques with controlled tuning of external parameters. In this paper, we present ...
Powder-level carbide modification controls HIP grain growth and enhances fatigue in reused additively manufactured superalloy
Inconel 718 dominates laser powder bed fusion (PBF-LB/M) builds as the benchmark Ni superalloy for its γ′/γ″ hardenability, weldability, and qualification pedigree, yet its fatigue resistance remains limited by porosity, tensile residual stresses, and microstructural heterogeneity ...
Magnetic Signature of Chiral Phonons Revealed by Neutron Spectroscopy in Ferrimagnetic Fe1.75Zn0.25Mo3O8
Lattice vibrations can carry angular momentum and magnetic moments under broken inversion or time-reversal symmetry, forming so-called chiral phonons. While such excitations have been explored in nonmagnetic systems via optical probes, their direct detection in magnetic materials and coupling to spin excitations remain largely unexplored. Here, using neutron spectroscopy, ...
Topological metal-insulator transition within the ferromagnetic state
A major challenge in condensed matter physics is integrating topological phenomena with correlated electron physics to leverage both types of states for next-generation quantum devices. Metal-insulator transitions are central to bridging these two domains while simultaneously serving as on-off switches for electronic states. Here, we demonstrate ...
