Paramagnetic Reentrance Effect in NS Proximity Cylinders

A scenario for the unusual paramagnetic reentrance behavior at ultra-low temperatures in Nb-Ag, Nb-Au, and Nb-Cu cylinders is presented. For the diamagnetic response down to temperatures of the order 15 mK, the standard theory (quasi-classical approximation) for superconductors appears to work very well, assuming that Ag, Au, and Cu remain in the normal state except for the proximity-induced superconductivity. Here it is proposed that these noble metals may become p-wave superconductors with a transition temperature of order 10 mK. Below this temperature, p-wave triplet superconductivity emerges around the periphery of the cylinder. The diamagnetic current flowing in the periphery is compensated by a quantized paramagnetic current in the opposite direction, thus providing a simple explanation for the observed increase in the susceptibility at ultra-low temperatures.Comment: RevTex, 8 pages with 1 eps figur

POS1 - Novel Design For Test (DFT) Concept to Check the Spectral Mask Compliance Defined in the IEEE Std. 802.15.6-2012 of Wireless-Body-Area-Network (WBAN) IC-Devices

In this paper, we introduce a novel design for test (DFT) concept to check the compliance of wireless-body-areanetwork devices for medical applications with the spectral mask for IR-UWB and FM-UWB defined in chapter 9.13 of the IEEE Std. 802.15.6-2012. The design enables a fast and repeatable ICproduction test solution for medium to high volume testing, which is independent of the tester type and does not need any extra circuitry on a test board / device interface board

Incorporation dynamics of molecular guests into two-dimensional supramolecular host networks at the liquid–solid interface

The objective of this work is to study both the dynamics and mechanisms of guest incorporation into the pores of 2D supramolecular host networks at the liquid–solid interface. This was accomplished by adding molecular guests to prefabricated self-assembled porous monolayers and the simultaneous acquisition of scanning tunneling microscopy (STM) topographs. The incorporation of the same guest molecule (coronene) into two different host networks was compared, where the pores of the networks either featured a perfect geometric match with the guest (for trimesic acid host networks) or were substantially larger than the guest species (for benzenetribenzoic acid host networks). Even the moderate temporal resolution of standard STM experiments in combination with a novel injection system was sufficient to reveal clear differences in the incorporation dynamics in the two different host networks. Further experiments were aimed at identifying a possible solvent influence. The interpretation of the results is aided by molecular mechanics (MM) and molecular dynamics (MD) simulations
