Summary: We conducted polarized small-angle and wide-angle neutron scattering experiments on 420 nm-sized hollow Fe3O4 spherical particles. Each particle is a mesocrystal composed of small nanoparticles with the same crystallographic orientation. We used polarized neutron experiments to evaluate the magnetic correlations during magnetization process. Our results show that the perpendicular magnetization component maximizes around zero applied field, while the parallel component minimizes, both below and above the Verwey transition temperature. Our calculations suggest the reorientation of the vortex core towards the magnetocrystalline anisotropy axis at low applied fields. We also found that the magnetic domain length obtained from wide-angle scattering is comparable to the size of the small nanoparticles forming the hollow sphere, indicating that magnetic correlations within the nanoparticles retain during magnetization process.

Summary: This study presents a facile method for the synthesis of unconventional amorphous hollow-silica nanostructures with controllable surface curvatures, symmetries, and interior architectures. The key role of transiently in situ crystallized metal coordination complexes as a template is identified for the differential silica growth that produces different nanostructures. Furthermore, crystal-like well-defined polygonal h-SiNSs can be assembled into highly ordered mesoscale materials with customizable cavities and nanospaces, which differ from conventionally assembled materials.

Summary: Systematic peptide sequence variation in a series of gold-binding peptide conjugate molecules can affect both the assembly of peptide conjugates and the synthesis, assembly, and optical properties of gold nanoparticle superstructures. Depending on the hydrophobicity of a single-amino acid variant, the conjugates yield either dispersed gold nanoparticles or helical superstructures. Subtle changes to peptide sequence, via single-amino acid variation in the beta-sheet region, can be leveraged to program structural control in chiral gold nanoparticle superstructures.

Summary: We demonstrate that a weak nonlinear response of a probe beam can be modulated and controlled by a pump beam in plasmonic nanosuspensions, resulting in the generation of ring-shaped patterns.
