Wigner Gaussian dynamics: Simulating the anharmonic and quantum ionic motion

The atomic motion controls important properties of materials, such as thermal transport, phase transitions, and vibrational spectra. However, simulating the ionic dynamics is exceptionally challenging when quantum fluctuations are relevant (e.g., at low te ...

Multi-sample/multi-nucleus parallel polarization and monitoring enabled by a fluid path technology compatible cryogenic probe for dissolution dynamic nuclear polarization

Andrea Capozzi, Jean-Noël Hyacinthe, Thanh Phong Kevin Lê

Low throughput is one of dissolution Dynamic Nuclear Polarization (dDNP) main shortcomings. Especially for clinical and preclinical applications, where direct 13C nuclei polarization is usually pursued, it takes hours to generate one single hyperpolarized ...

Efficient Semiclassical Evaluation of Electronic Coherences in Polyatomic Molecules

Jiri Vanicek, Nikolay Golubev

Exposing a molecule to an intense light pulse can create a nonstationary quantum state, thus launching correlated dynamics of electrons and nuclei. Although much had been achieved in the understanding of fundamental physics behind the electron-nuclear inte ...

Comprehensive analysis of the circadian nuclear and cytoplasmic transcriptome in mouse liver

Felix Naef, Cédric Gobet, Benjamin Dieter Weger, Clémence Yumie Syloun Hurni

In eukaryotes, RNA is synthesised in the nucleus, spliced, and exported to the cytoplasm where it is translated and finally degraded. Any of these steps could be subject to temporal regulation during the circadian cycle, resulting in daily fluctuations of ...

Dynamical Control of Nuclear Isomer Depletion via Electron Vortex Beams

Fabrizio Carbone, Simone Gargiulo

Some nuclear isomers are known to store a large amount of energy over long periods of time, with a very high energy-to-mass ratio. Here, we describe a protocol to achieve the external control of the isomeric nuclear decay by using electron vortex beams who ...

Superconductors for fusion: a roadmap

Pierluigi Bruzzone, Kamil Sedlák, Nikolay Bykovskiy, Rainer Wesche

With the first tokamak designed for full nuclear operation now well into final assembly (ITER), and a major new research tokamak starting commissioning (JT60SA), nuclear fusion is becoming a mainstream potential energy source for the future. A critical par ...

A risk-based multi-level stress test methodology: application to six critical non-nuclear infrastructures in Europe

Anton Schleiss, Daniela Rodrigues, José Pedro Gamito de Saldanha Calado Matos

Recent natural disasters that seriously affected critical infrastructure (CI) with significant socio-economic losses and impact revealed the need for the development of reliable methodologies for vulnerability and risk assessment. In this paper, a risk-bas ...

Synthesis, reactivity, and environmental relevance of uranyl(V) complexes.

Radmila Faizova

Knowledge of fundamental chemical properties of all environmentally relevant uranium species is essential to understand environmental uranium mobility and develop novel remediation strate-gies. A myriad of uranium(VI) and uranium(IV) compounds has been stu ...

NUMERICAL WEATHER MODELS FOR RESOURCE ASSESSMENT OF ALPINE WIND POWER

Introduction With the decision to move away from nuclear-based power generation, Switzerland has committed itself to an ambitious energy transition. Wind power appears a suitable candidate to partially fill the gap left behind by nuclear. It has a favorabl ...

Non-crystalline tetravalent uranium species in the subsurface: formation and stability

Luca Loreggian

Uranium (U) contamination of ground and surface waters poses an acute hazard on the ecosystem and human health. Since the discovery of microbial U(VI) reduction, U bioremediation has been explored as a promising and cost-effective method compared to tradit ...
