Electron-phonon driven unconventional superconductivity: The role of small Fermi energies and of nonadiabatic processes

The very concept of high-T-c superconductivity has originated from the discovery of superconductivity in copper oxides by Bednorz and Muller in 1986. Soon after their discovery, cuprates were recognized as undoubtedly complex and radically unconventional s ...

Atomistic simulation and electron microscopy to characterize grain boundaries in doped beta-tricalcium phosphate ceramics

Gabrielle Anne Laguisma Sblendorio

The limitations and potential complications correlated with autogenous bone grafts have raised interest in the development of synthetic bone graft substitutes. ß-tricalcium phosphate (ß-TCP) is one of the most promising materials for synthetic bone graft s ...

In situ nanoscale studies of copper-based catalysts for carbon dioxide electroreduction

Karla Banjac

The urgency of climate change demands the simultaneous removal of carbon dioxide from the atmosphere and the transition to renewable energy sources. This aim is realizable through electrochemical reduction of carbon dioxide (CO2RR), which is a promising ro ...

Superexchange mechanism and quantum many body excitations in the archetypal di-Cu oxo-bridge

Edward Baxter Linscott, Cédric Weber

The hemocyanin protein binds and transports molecular oxygen via two copper atoms at its core. The singlet state of the Cu2O2 core is thought to be stabilised by a superexchange pathway, but detailed in situ computational analysis is complicated by the mul ...

A New Concept of Sensor for Ultra-high Levels of Radiation based on Radiation Enhanced Oxidation of Copper Thin-films

Georgi Gorine

The Future Circular Collider (FCC) is the envisioned particle accelerator to be installed in the Geneva area (Switzerland). It could achieve an energy of 100 TeV by colliding proton beams (FCC-hh) travelling through a 100 km tunnel. Unprecedented radiation ...

Dynamics of correlation-frozen antinodal quasiparticles in superconducting cuprates

Alberto Crepaldi

Many puzzling properties of high-critical temperature (T-c) superconducting (HTSC) copper oxides have deep roots in the nature of the antinodal quasiparticles, the elementary excitations with wave vector parallel to the Cu-O bonds. These electronic states ...

Influence of the thickness of a nanometric copper interlayer on Au/dielectric thermal boundary conductance

Ludger Weber, Maïté Blank

The influence of the thickness of a thin (1.5-30 nm) copper layer on the thermal boundary conductance (TBC) at the interface between gold and silicon, sapphire and diamond, respectively, was studied using Time Domain Thermoreflectance. Overall, a monotonic ...

Supported photocatalysts for model pollutant degradation and bacterial inactivation

Laura Victoria Suárez Murillo

Water quality and bacterial infections are directly related to human health and wellbeing, thus waste water treatment is a necessary procedure for avoiding disturbances to ecosystems and for assuring human health. Furthermore, bacterial contamination in wa ...

Intrachain antiferromagnetic exchange in a 1D branched-chain built of two different copper(II) centres interlinked by end-on azido and phenoxo bridges: electron density map, electrochemical and magnetic properties

Henrik Moodysson Rønnow, Kurt Schenk, Philip Pattison, Krunoslav Prsa, Arash Alahgholipour Omrani, Noore Elahi Shaik

A 1D, end-on azido- and phenoxo-bridged, coordination polymer, Cu-2(mu-NAPPR)(mu(1,1)-N-3)(2) (1), (NAPPR(2-) = 1,3-bis(naphthylideneimino) propane dianion), was synthesized and characterized. The 1D branched-chain is built of two types of slightly di ...

Luttinger liquid behavior in the alternating spin-chain system copper nitrate

Felix Groitl

We determine the phase diagram of copper nitrate Cu(NO3)(2)center dot 2.5D(2)O in the context of quantum phase transitions and novel states of matter. We establish this compound as an ideal candidate to study quasi-1D Luttinger liquids, 3D Bose-Einstein-Co ...
