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 ...

Delayed gamma fraction determination in the zero power reactor CROCUS

Andreas Pautz, Vincent Pierre Lamirand, Oskari Ville Pakari, Pavel Frajtag, Tom Mager

Gamma rays are an inextricable part of a nuclear reactor's radiation field, and as such require characterization for dose rate estimations required for the radiation protection of personnel, material choices, and the design of nuclear facilities. Most comm ...

The emergence of magnetic ordering at complex oxide interfaces tuned by defects

Paul Muralt, Vasiliki Tileli, Daesung Park, Gurpreet Singh, Jing Li, Yen-Chun Chen

Complex oxides show extreme sensitivity to structural distortions and defects, and the intricate balance of competing interactions which emerge at atomically defined interfaces may give rise to unexpected physics. In the interfaces of non-magnetic complex ...

A Nine Decade Femtoampere Current to Frequency Converter

Evgenia Voulgari

Various applications require ultra-low current sensing. Some of these applications are related to ionizing radiation detection. Radiation monitoring is important in particle physics experiments, nuclear facilities, hadron therapy institutes and hospitals. ...

Anthropogenic- and natural sources of dust in peatland during the Anthropocene

Alexandre Buttler, Vincent Eric Jules Jassey, Mariusz Lamentowicz

As human impact have been increasing strongly over the last decades, it is crucial to distinguish human-induced dust sources from natural ones in order to define the boundary of a newly proposed epoch -the Anthropocene. Here, we track anthropogenic signatu ...

Dynein-Based Accumulation of Membranes Regulates Nuclear Expansion in Xenopus laevis Egg Extracts

Christoph Merten

Nuclear size changes dynamically during development and has long been observed to correlate with the space surrounding the nucleus, as well as with the volume of the cell. Here we combine an in vitro cell-free system of Xenopus laevis egg extract with micr ...

Risks and Reliability in a Fully Renewable Switzerland

Michael Lehning, Annelen Kahl, Stuart John Bartlett

In Switzerland, the government has made ambitious plans for a major energy transition. There is a planned phase out of nuclear facilities by mid-century, their capacity replaced by an expansion of hydroelectric infrastructure, new geothermal installations, ...

Simplified wide-column model for the blind prediction shake table test of a U-shaped wall building

João Saraiva Esteves Pacheco de Almeida

Reinforced concrete (RC) structures with tri-dimensional asymmetries tend to exhibit torsional effects that are of great concern in the field of earthquake engineering, in particular at large ductility levels where they become more relevant [MAN09]. In nuc ...

Reversible acetylation of PGC-1: connecting energy sensors and effectors to guarantee metabolic flexibility

Johan Auwerx, Kristina Schoonjans, Ellen Helena Jeninga

rganisms adapt their metabolism to meet ever changing environmental conditions. This metabolic adaptation involves at a cellular level the fine tuning of mitochondrial function, which is mainly under the control of the transcriptional co-activator prolifer ...

Snapshots of cooperative atomic motions in the optical suppression of charge density waves

Helmuth Berger

Macroscopic quantum phenomena such as high-temperature superconductivity, colossal magnetoresistance, ferrimagnetism and ferromagnetism arise from a delicate balance of different interactions among electrons, phonons and spins on the nanoscale(1). The stud ...
