In nuclear magnetic resonance (NMR), one of the most serious inherent challenges is the low sensibility of nuclei. In order to enhance the signal of NMR experiments, the technique of dynamic nuclear hyperpolarisation (DNP) was introduced in the 1950s, lead ...

Nanoscale structural oscillations in perovskite oxides induced by oxygen evolution

Vasiliki Tileli

Understanding the interaction between water and oxides is critical for many technological applications, including energy storage, surface wetting/self-cleaning, photocatalysis and sensors. Here, we report observations of strong structural oscillations of B ...

Nanoscale topographical control of capillary assembly of nanoparticles

Jürgen Brugger, Olivier Martin, Duncan Alexander, Massimo Mastrangeli, Elmira Shahrabi, Jérémy Butet, Valentin Flauraud, Gabriel David Bernasconi

Predetermined and selective placement of nanoparticles onto large-area substrates with nanometre-scale precision is essential to harness the unique properties of nanoparticle assemblies, in particular for functional optical and electro-optical nanodevices. ...

Fermi resonance in CO2: Mode assignment and quantum nuclear effects from first principles molecular dynamics

Sara Bonella, Guillaume André Jean Fraux

Vibrational spectroscopy is a fundamental tool to investigate local atomic arrangements and the effect of the environment, provided that the spectral features can be correctly assigned. This can be challenging in experiments and simulations when double pea ...

Gate-tunable black phosphorus spin valve with nanosecond spin lifetimes

Ahmet Avsar

Two-dimensional materials offer new opportunities for both fundamental science and technological applications, by exploiting the electron's spin. Although graphene is very promising for spin communication due to its extraordinary electron mobility, the lac ...

Dynamic Nuclear Polarization of Long-Lived Nuclear Spin States in Methyl Groups

Geoffrey Bodenhausen, Aurélien Bornet, Sami Jannin, Basile Vuichoud, Arthur César Pinon, Gabriele Stevanato, Daniele Mammoli

We have induced hyperpolarized long-lived states in compounds containing C-13-bearing methyl groups by dynamic nuclear polarization (DNP) at cryogenic temperatures, followed by dissolution with a warm solvent. The hyper polarized methyl long-lived states g ...

Ab initio study of electron energy loss spectra of bulk bismuth up to 100 eV

Iurii Timrov

The dynamical charge-density response of bulk bismuth has been studied within time-dependent density functional perturbation theory, explicitly accounting for spin-orbit coupling. The use of the Liouville-Lanczos approach allows us to calculate electron en ...

A novel synthetic approach of cerium oxide nanoparticles with improved biomedical activity

Francesco Stellacci, Andrzej Sienkiewicz, Marta Mameli, Fanny Caputo

Cerium oxide nanoparticles (CNPs) are novel synthetic antioxidant agents proposed for treating oxidative stress-related diseases. The synthesis of high-quality CNPs for biomedical applications remains a challenging task. A major concern for a safe use of C ...

Broadband single-chip transceivers for compact NMR probes

Marco Grisi

Nuclear magnetic resonance (NMR) is one of the most relevant spectroscopic tools in use today. However, NMR requires relatively expensive and complicated experimental settings given by the combination of high homogeneous magnetic fields and a relatively co ...
