North Korea's test was underground, but unless it was exceptionally well-contained, radioactive noble gases primarily radioxenon isotopes could start leaking into the atmosphere in the next couple days, says Anders Ringbom, a nuclear physicist at the Swedish Defence Research Agency in Stockholm.
Binary fluorides of lighter noble gases are exceptionally unstable: argon and hydrogen fluoride combine under extreme conditions to give argon fluorohydride.
Schaefer's 1995 Riesling Auslese "Gold Cap" from the Domprobst is a late-harvest masterpiece, rich in the lush exotic fruit aromas from botrytis (noble rot), but still exceptionally clean and fresh.
Compared to other sedimentary deposits of known or suspected impact origin, some noble metals are present in exceptionally high concentrations.
But I can say this: We did a great, bold, noble, and honorable thing, and we did it exceptionally well.
Rainiharo gained initial access to the court through his father, Andriantsilavonandriana, a hova (commoner) who had exceptionally been accorded the privilege of joining King Andrianampoinimerina's inner circle of noble advisers.
As contemporary observers rarely failed to mention, he was exceptionally tall, strong, and graceful, enjoyed a spotless personal reputation, and seemed almost impossibly noble and virtuous.
Significant plasmonic enhancement of fluorescent dyes is observed, apparently the result of increased fluorophore stability permitting longer probing times with higher excitation energy; noble metal nanoparticle plasmons can enhance the signaling of fluorophores by two orders of magnitude or more creating exceptionally bright labels (Jain et al., 2008; Demchenko, 2013).
