Anomalous interfacial dynamics of single proton charges in binary aqueous solutions

Aleksandra Radenovic, Evgenii Glushkov, Ahmet Avsar, Jean Camille Benjamin Comtet, Miao Zhang

Our understanding of the dynamics of charge transfer between solid surfaces and liquid electrolytes has been hampered by the difficulties in obtaining interface, charge, and solvent-specific information at both high spatial and temporal resolution. Here, w ...

Direct observation of water-mediated single-proton transport between hBN surface defects

Aleksandra Radenovic, Evgenii Glushkov, Ahmet Avsar, Jean Camille Benjamin Comtet, Benoît Grosjean

Super-resolution microscopy of defects in a two-dimensional material unveils the transport of single proton charges at solid/water interfaces. Aqueous proton transport at interfaces is ubiquitous and crucial for a number of fields, ranging from cellular tr ...

Concrete and Metallic Structures Activation Calculations

Harrison Gavotto

The objective of this report is to detail the work done during the TP IV project at EPFL. The idea is to look into the activation of concrete and metallic structures of the EPFL’s nuclear reactor: CROCUS. This study has been done by two ways: MCNP computat ...

Method for hyperpolarization transfer in the liquid state

Geoffrey Bodenhausen, Sami Jannin

A method for producing a hyperpolarized sample for use in a magnetic resonance investigation, with the following steps: a) providing a solid sample (50), containing long T1 nuclei and short T1 nuclei in the same molecules (51) b) hyperpolarizing the short ...

Conceptual Design Report for a Beta-Beam Facility

Stefania Trovati, Vasilis Vlachoudis, Marco Silari

The Beta-Beam is a concept of large-scale facility that aims at providing pure electronic neutrino and antineutrino beams for the measurement of electron and muon neutrino oscillations. Beta-decaying nuclides are produced in large amounts in a facility of ...

Apparent transverse relaxation rates in systems with coupled carbon-13 spins

Geoffrey Bodenhausen, Nicolas Aeby

In systems with homonuclear scalar couplings, the envelopes of spin echoes obtained with simple refocusing pulses or trains of such pulses are normally modulated so that it is difficult to extract transverse relaxation rates. It has been shown recently tha ...

The origin of 60Fe and other short-lived radionuclides in the early solar system

Anders Meibom

Establishing the origin of short-lived radionuclides (SLRs) with half-lives ≤100 Myr has important implications for the astrophysical context of our Sun's birth place. We review here the different origins proposed for the variety of SLRs present in the sol ...

Submicro- and Nano-Structured Porous Materials for Production of High-Intensity Exotic Radioactive Ion Beams

Sandrina Fernandes

ISOLDE, the CERN Isotope Separator On-line DEvice is a unique source of low energy beams of radioactive isotopes - atomic nuclei that have too many or too few neutrons to be stable. The facility is like a small 'chemical factory', giving the possibility of ...

Validation of Monte Carlo predictions of LWR-PROTEUS safety parameters using an improved whole-reactor model

Rakesh Chawla, Fabian Jatuff, Michaël Plaschy

The recent experimental programme conducted in the PROTEUS research reactor at the Paul Scherrer Institute (PSI) has concerned detailed investigations of advanced light water reactor (LWR) fuels. More than fifteen different configurations of the multi-zone ...

Long-lived states to sustain hyperpolarized magnetization

Geoffrey Bodenhausen, Jean-Philippe Ansermet, Arnaud Comment, Sami Jannin, Paul Romeo Vasos, Riddhiman Sarkar, Puneet Ahuja

Major breakthroughs have recently been reported that can help overcome two inherent drawbacks of NMR: the lack of sensitivity and the limited memory of longitudinal magnetization. Dynamic nuclear polarization (DNP) couples nuclear spins to the large reserv ...
