In recent decades, the facilities with radioactive ion beam models to study nuclear magnetic moments make it possible to measure the magnetic moments of neutron-rich and proton-rich nuclei with high precision.
On the theoretical side, many nuclear structure models, including advanced shell models, and self-consistent mean-field theories, have succeeded analyzing many nuclear structure properties. However, the extension of these models to the study of nuclear magnetic moments is quite limited and unsatisfactory. The magnetic dipole moments of most atomic nuclei throughout the periodic table still remain unexplained and the under-lying physics mechanism is not fully understood.
In view of these facts, SCIENCE CHINA: Physics, Mechanics & Astronomy editorial board has invited a number of major theoretical nuclear physicists in the research field of nuclear magnetic moments and related topics to contribute to this special topic. However, due to the page limitation the discussion on the topic presents just a fraction of the progress in this field.
This special issue on "Nuclear magnetic moments and related topics" consists of ten selected papers, which review the progress not only on the theoretical description of nuclear magnetic moments, but also on the recent development of closely related subjects including nuclear pairing, quantum phase transitions as well as nuclear masses in microscopic models. This issue is also intended to identify common goals to deepen understanding of nuclear structure.
In summary, theoretical description of nuclear magnetic moments is one of the long-standing subjects. More important progress will be made in the near future.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
