In situ X-ray scattering reveals coarsening rates of superlattices self-assembled from electrostatically stabilized metal nanocrystals depend non-monotonically on driving force

Posted by klaurent Berkeley

Kavli Affiliate: Naomi Ginsberg | Summary:Self-assembly of colloidal nanocrystals (NCs) into superlattices (SLs) is an appealing strategy to design hierarchically organized materials with new functionalities. Mechanistic studies are still needed to uncover the design principles for SL self-assembly, but such studies have been difficult to perform due to the fast time- and short length scales […]

Modular DNA origami-based electrochemical detection of DNA and proteins

Posted by klaurent Caltech

Kavli Affiliate: Paul W. K. Rothemund | Summary:The diversity and heterogeneity of biomarkers has made the development of general methods for single-step quantification of analytes difficult. For individual biomarkers, electrochemical methods that detect a conformational change in an affinity binder upon analyte binding have shown promise. However, because the conformational change must operate within a […]

Wigner Molecular Crystals from Multi-electron Moiré Artificial Atoms

Posted by klaurent Berkeley

Kavli Affiliate: Alex Zettl | Summary:Semiconductor moiré superlattices provide a versatile platform to engineer new quantum solids composed of artificial atoms on moiré sites. Previous studies have mostly focused on the simplest correlated quantum solid – the Fermi-Hubbard model – where intra-atom interactions are simplified to a single onsite repulsion energy U. These studies have […]
