Abstract

Out of the frying pan: Hot spots can greatly increase the sensitivity of surface‐enhanced Raman scattering, but they remain poorly understood. A new strategy based on plasma etching (see picture) can be used to isolate and exclusively probe the SERS‐active molecules adsorbed in the hot‐spot region between two silver nanocubes.magnified image

## Abstract **Hotspots** können die Empfindlichkeit der oberflächenverstärkten Raman‐Streuung (SERS) stark erhöhen, doch erklärt werden konnte dieses Phänomen bisher nicht. Eine neue Strategie (siehe Bild) setzt auf das Plasmaätzen, um an Hotspots zwischen zwei Silbernanowürfeln adsorbierte SERS‐ak

The global network of plate boundaries c
The global network of plate boundaries can be divided into two discrete subnetworks containing the spreading and subduction boundaries, respectively. We advocate that this division is a stable pattern that derives from consistency rules in rigid-plate rotations. Subduction is distributed along a single, long subnetwork, hence organizing the mantle convection as a single, long downwelling wall and two lower mantle upwelling columns, at the Pacific and African sides of the Earth, respectively. The columns should merge upward between Antarctica and Australia to reach the single, long spreading subnetwork. The flow encircles two toric volumes that escape convectional mixing and are the likely sources of the two, Atlantic–Indian and Pacific, hot spot domains.
