Fabrication Optimization of van der Waals Metasurfaces: Inverse Patterning Boosts Resonance Quality Factor

open access: yesAdvanced Optical Materials, EarlyView.
An optimized fabrication approach for the nanostructuring of optical metasurfaces from van der Waals materials like hexagonal boron nitride is presented. The resonator geometries show enhanced geometric homogeneity, resulting in a significant increase in quality factors of symmetry‐protected bound states in the continuum resonances.

Cu(I)‐Catalyzed Interrupted Cycloaddition Between Azides, Ag(I)‐Acetylides, and Diorganoyl Dichalcogenides

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Unleashing the power of Ag(I)‐acetylides with LiCl/dimethyl sulfoxide (DMSO). The LiCl/DMSO mixture have an unexplored ability to dramatically increase the solubility of Ag(I)‐acetylides regardless of their molecular structure, which is explored to achieve high chemoselectivity in the Cu(I)‐catalyzed interrupted cycloaddition between organic azides, Ag(
