An article in Physical Review Letters reports theoretical calculations predicting that a 2D second-order topological insulator state exists in the gaps separating the low-energy flat bands from higher-energy bands in twisted bilayer graphene and twisted bilayer boron nitride.
An article in Nature reports measurements of lattice vibrations in bilayer graphene twisted at very small angles by tip-enhanced nano-Raman spectroscopy.
During fibrotic diseases, functional tissue parenchyma progressively transforms into stiff, disorganized and non-functional tissue causing organ failure. The underlying multitude of interconnected changes in the cellular microenvironment can be investigated using bioengineered fibrosis models.
Lipid nanoparticles have been developed as vehicles for small molecule delivery by the nanomedicine and materials communities and are now a key component of COVID-19 mRNA vaccines.
The design of new functional polymers depends on the successful navigation of their structure-function landscapes. Advances in combinatorial polymer chemistry and machine learning provide exciting opportunities for the engineering of fit-for-purpose polymeric materials.
An article in Nature Catalysis reports an approach to integrating different single-atom catalysts within one system to simultaneously perform oxidation and reduction reactions.
An article in Nature Photonics reports a one-dopant alloying strategy for the synthesis of monodisperse perovskite nanoparticles for high-efficiency light-emitting diodes.
Cell-released biological nanoparticles, that is, extracellular vesicles (EVs), are emerging drug carriers with high complexity. EV-based drug delivery exploits intrinsic mechanisms for molecular transport in the body. Integrating EV biology and manufacturing with clinical insights from synthetic nanoparticles is likely to substantially advance the field of drug delivery.
