“…Here, we demonstrate the first observation on a synergistic effect caused by two neighboring Al centers interacting with the same silanol group in flame-made ASAs with high Al content. The two close Al centers decrease the electron density on the silanol oxygen and thereby enhance its acidity, which is comparable to that of dealuminated zeolites, while ASAs with small or moderate Al contents provide mainly moderate acidity, much lower than that of zeolites. …”

“…The proposed AAO-based antenna reduces the size (1.87 (0.18λ(0)) mm × 2.34 (0.22λ(0)) mm) of the antenna in proportion to the dielectric constant (ε(r) = 6.7), which is higher than those of the conventional materials such as polycarbonates (PC) or a flame retardant (FR4). In addition, it is possible to precisely control the dielectric layer dimensions and generate a dielectric layer on the metal substrate itself, which greatly increases the design freedom. …”
