Magnetic skyrmions are two-dimensional, vortex-like spin states that carry a topological number. Due to their particle nature and emergent electromagnetic properties, skyrmions are viewed as promising candidates for information transport in future spintronics devices. [...]

This work is dedicated to the highly discussed formation mechanism of amorphous calcium carbonate (ACC), its role in nonclassical crystallization, and amorphous carbonates as a precursor for functional metal oxides. Decrypting the formation mechanism of ACC provides a new environmentally benign synthesis pathway for complex hierarchically structured nanomaterials. [...]

Lipid structural diversity strongly affects biomembrane chemico-physical and structural properties in addition to membrane-associated events. At high concentrations, cholesterol increases membrane order and rigidity, while polyunsaturated lipids are reported to increase disorder and flexibility. [...]

We study the dynamics of pure oleic acid and grafted oleic acid synthesized by decomposing iron oleate into oleic acid grafted iron oxide nanoparticles. Our quasielastic neutron scattering study shows that oleic acid dominantly performs translational diffusion at room temperature [...]

The segmental dynamics of one-component nanocomposites (OCNC) is significantly influenced by the molecular weight (Mw) of the grafted polymer. Neutron backscattering shows that compared to the neat polymer the OCNCs exhibit a shift from slower segmental dynamics at low Mw to faster dynamics at high Mw. [...]

Tuning the electronic properties of transition-metal and rare-earth compounds by virtue of changes of the crystallographiclattice constants offers controlled access to new forms of order. We review the development oftungsten carbide and moissanite Bridgman cells conceived for studies of the electrical resistivity up to 10GPa,as well as bespoke diamond anvil cells developed for neutron depolarization studies up to 20GPa.

Novel composite hydrogels representing interpenetrating polymeric networks (IPN) have been synthesized and consisted of Gluconacetobacter xylinus cellulose (GxC) and poly-1-vinyl-1,2,4-triazole (PVT) with Cu2⁺. The composite hydrogels’ mesostructure has been studied from 1.6 ​nm to 2.5 ​μm by small-angle and ultra-small-angle neutron scattering methods. [...]
