Immune complexes (ICs), formed via antibody (Ab)-antigen (Ag) binding, trigger diverse immune responses, which are critical for natural immunity and have uses for vaccines and immunotherapies. While IC-elicited immune responses depend on its structure, existing methods for IC synthesis produce heterogeneous assemblies, which limits control over their cellular interactions and pharmacokinetics. In this study, we demonstrate the use of DNA origami to create synthetic ICs with defined shape, size, and solubility by displaying Ags in prescribed spatial patterns.

Oxygen vacancies in Ruddlesden-Popper (RP) perovskites (PV) [AO][ABO] play a pivotal role in engineering functional properties and thus understanding the relationship between oxygen-vacancy distribution and physical properties can open up new strategies for fine manipulation of structure-driven functionalities. However, the structural origin of preferential distribution for oxygen vacancies in RP structures is not well understood, notably in the single-layer ( = 1) RP-structure. Herein, the = 1 RP phase SrNdZnO was rationally designed and structurally characterized by combining three-dimensional (3D) electron diffraction and neutron powder diffraction.

The impacting research on emotions of the last decades was carried out with different methods. The most popular was based on the use of a validated sample of slides, the International Affective Pictures System (IAPS), divided mainly into pleasant, neutral and unpleasant categories, and on fMRI as a measure of brain activation induced by these stimuli. With the present coordinate-based meta-analysis (CBMA) based on ALE approach, we aimed to unmask the main brain networks involved in the contrast of pleasant vs.

Metal oxide photocatalysts loaded with metal species are extremely important in photocatalysis. The physicochemical states of metal species, as well as the interaction between metal species and support, determine the transfer of charge carriers between the heterointerface, which has a significant impact on photocatalytic activity. Here, we prepared anatase TiO nanosheets (TIO) modified with different Ag species, including single atoms, clusters, and nanoparticles, using a ligand-mediated method.

Structural changes in Ru- and Rh-loaded magnesium oxide (MgO) subjected to thermal treatment were investigated by using X-ray absorption spectroscopy. The thermal treatment of the MgO-loaded Ru and Rh nanoparticles led to the formation of Ru-MgO and Rh-MgO solid solutions, respectively. The valences of Ru and Rh in the solutions were 4+ and 3+, respectively, as determined by the Ru and Rh K-edge X-ray absorption near-edge structure (XANES).
