Atomically dispersed Rh on N-doped carbon exhibits promising electrocatalytic properties for formic acid oxidation while Rh nanoparticles are inert towards this reaction. The Rh single atoms exhibit high tolerance to CO poisoning compared to Rh nanoparticles.
Knowledge and control of the dynamic response in micromagnetic configurations is important both for understanding their fundamental properties and for their use in technological applications. Pump–probe magnetic laminography now unveils the evolution of the magnetization in a three-dimensional system with nanoscale resolution.
The controlled creation of magnetic skyrmions is a prerequisite for their application in future spintronic devices. While charge currents can induce skyrmions via spin torque, surface acoustic waves can do the same through magnetoelastic coupling of inhomogeneous strain paired with thermal fluctuations.
Topological insulators have been studied primarily with regard to the behaviour of electrons. A theoretical study now shows that a single layer of a metal dichalcogenide can become a topological insulator for excitons.
Phage capsids modified with spatially defined patterns of host cell ligands can act as multivalent binders for the influenza A virus to prevent viral infection.
Charge disproportionation in thin molecular films of a metal–organic complex enables the realization of a ternary memristor and binary memcapacitor.
Atomically dispersed Rh on N-doped carbon exhibits 28- and 67-fold enhancements compared with state-of-the-art Pd/C and Pt/C, despite the low activity of Rh/C. The Rh single atoms exhibit high tolerance to CO poisoning compared to Rh nanoparticles.
A multimodal imaging approach using a high-density lipoprotein-derived nanotracer with a perfluoro-crown ether payload enables myeloid cell dynamics to be studied in vivo in mouse models of atherosclerosis and myocardial infarction.
Dual-targeting nanoparticle vaccine elicits a therapeutic antibody response against chronic hepatitis B
A ferritin nanoparticle that delivers the preS1 domain of the large hepatitis B surface protein to two specific myeloid cell populations provides a therapeutic vaccination strategy for the treatment of chronic hepatitis B.
