WebMar 14, 2024 · Here we report the synthesis of a novel buckybowl (7) with a high bowl-to-bowl inversion barrier (ΔG ‡ = 38 kcal mol −1), which renders the rate of inversion slow enough at room temperature to establish two chiral polycyclic aromatic hydrocarbons (PAHs).By strategic fusion of eight-membered rings to the rim of 7, the chiral hybrids 8 … WebJan 29, 2024 · We study chiral rings of 4d N $$ \\mathcal{N} $$ = 1 supersymmetric gauge theories via the notion of K-stability. We show that when using Hilbert series to perform the computations of Futaki invariants, it is not enough to only include the test symmetry information in the former’s denominator. We discuss a way to modify the numerator so …
