Characteristic rupture height of the mediating air film beneath an impacting drop on atomically smooth mica

Before a droplet can contact a surface during impact, it must first displace the air beneath it. Over a wide range of impact velocities, the droplet first squeezes the air into a thin film, enhancing its resistance to drainage; this slows the progress of t ...

Orders That Are Etale-Locally Isomorphic

Eva Bayer Fluckiger

Let R be a semilocal Dedekind domain with fraction field F. It is shown that two hereditary R-orders in central simple F-algebras that become isomorphic after tensoring with F and with some faithfully flat etale R-algebra are isomorphic. On the other hand, ...

Orders that are étale-locally isomorphic

Eva Bayer Fluckiger, Mathieu Huruguen

Let R be a semilocal Dedekind domain with fraction field F. It is shown that two hereditary R-orders in central simple F-algebras that become isomorphic after tensoring with F and with some faithfully flat étale R-algebra are isomorphic. On the other hand, ...

Focusing and Extraction of Light mediated by Bloch Surface Waves

Hans Peter Herzig, Elsie Barakat

The control of emission from localized light sources is an objective of outstanding relevance in nanophotonics. In a recent past, a large number of metallic nanostructures has been proposed to this end, wherein plasmonic modes are exploited as energy carri ...

High throughput 3D super-resolution microscopy reveals Caulobacter crescentus in vivo Z-ring organization

Suliana Manley, Karin Lederballe Meibom, Seamus John Holden, Thomas Pengo

We created a high-throughput modality of photoactivated localization microscopy (PALM) that enables automated 3D PALM imaging of hundreds of synchronized bacteria during all stages of the cell cycle. We used high-throughput PALM to investigate the nanoscal ...

Induced magnetic fields in aromatic [n]-annulenes-interpretation of NICS tensor components

The components of nucleus-independent chem. shift (NICS) tensors for Dnh n-annulenes are discussed as indexes of the arom. character of electronic pi systems. The component corresponding to the principal axis perpendicular to the ring plane, NICSzz, is fou ...

The hetero-Diels-Alder addition of sulfur dioxide to 1-fluorobuta-1,3-dienes: The sofa conformations preferred by 6-fluorosultines (6-fluoro-3,6-dihydro-1,2-oxathiin-2-oxides) enjoy enthalpic and conformational anomeric effects

Pierre Vogel, Rosario Scopelliti

The reactivity of (E)- and (Z)-1-fluorobuta-1,3-diene ((E)- and (Z)-11), 2-fluorobutadiene (12). (E)and (Z)-1-(fluoromethylidene)-2-methylidenecyclohexane ((E)- and (Z)-13) toward SO2 has been explored and compared with that of (Z)- and (E)-1-(fluoromethyl ...
