摘要:Abstract(#br)Percutaneous left atrial appendage (LAA) closure is a routinely performed method to reduce the risk of stroke in patients suffering from atrial fibrillation, when an oral anticoagulation is no longer indicated due to relevant bleeding complications. Currently, the Am...

摘要:Abstract(#br)In this report we present results of a systematical study of relevant properties of superconducting Nb thin films of thickness from 8 to 200 nm deposited on Si. We have found that a reduction of thickness d below 50 nm leads to a significant decrease of the crit...

摘要:Abstract(#br)Using a dielectric resonator technique the magnetic field penetration depth λ and the energy gap Δ of two MgB 2 thin films were determined by measuring changes of resonance frequency with temperature. The exponential temperature dependence of λ is revealed at lo...

摘要:Summary(#br)Using a Collison nebulizer, aerosols of influenza (A/Udorn/307/72 H3N2) were generated within a controlled experimental chamber, from known starting virus concentrations. Air samples collected after variable suspension times were tested quantitatively using both ...

摘要:Abstract(#br)The coherence peak is observed in the temperature dependence of the real part of the microwave conductivity ( σ 1 ) of c -axis oriented MgB 2 thin film, which is extracted from microwave surface impedance ( Z s ) measurements using a sapphire resonator at 17.9 G...

摘要:Abstract(#br)In this paper improvements to a Near-Field Scanning Microwave Microscope (NSMM) are presented that allow the loss of high loss dielectric materials to be measured accurately at microwave frequencies. This is demonstrated by measuring polar liquids (loss tangent ...

摘要:Abstract(#br)We present here the temperature dependence of the real part of the microwave conductivity of MgB 2 thin film measured at 7.2 GHz. A pronounced peak occurs at a temperature around 0.6 times the critical temperature, same position as it did at 17.9 GHz [Jin et. al...
