In AIP Advances, researchers describe how to exploit DNA origami as a platform to build superconducting nanoarchitectures. The structures they built are addressable with nanometric precision that can be used as a template for 3D architectures that are not possible today via conventional fabrication techniques. Inspired by previous works using the DNA molecule as a template for superconducting nanowires, the group took advantage of a recent bioengineering advance known as DNA origami.

An international consortium of scientists, initiated by Reinhard Kienberger, Professor of Laser and X-ray Physics at the Technical University of Munich (TUM), several years ago, has made significant measurements in the femtosecond range at the U.S. Stanford Linear Accelerator Center (SLAC).
However, on these miniscule timescales, it is extremely difficult to synchronize the X-ray pulse that sparks a reaction in the sample on the one hand and the laser pulse which observes it on the other. This problem is called timing jitter, and it is a major hurdle in ongoing efforts to perform time-resolved experiments at XFELs with ever-shorter resolution.

Scientists from the Joint Institute for High Temperatures Russian Academy of Sciences (JIHT RAS) and Moscow Institute of Physics and Technology (MIPT) have experimentally confirmed the presence of an intermediate phase between the crystalline and liquid states in a monolayer dusty plasma system. The theoretical prediction of the intermediate - hexatic - phase was honoured with the Nobel Prize in Physics in 2016: the prize was awarded to Michael Kosterlitz, David Thouless and Duncan Haldane with the formulation for theoretical discoveries of topological phase transitions and topological phases of matter.
In a scientific article in the journal
Scientific Reports, the JIHT RAS scientists published their observations and detailed descriptions of experiments, during which they first observed the hexatic phase in two-dimensional structures in plasma. The paper describes methods for accurately identifying phase transition points and presents a detailed analy

Unique in Canada, the Advanced Laser Light Source Laboratory (ALLS) of the Institut national de la recherche scientifique (INRS) has begun upgrading the power of its lasers in early 2020. Under the responsibility of Professor François Légaré, the ALLS infrastructure has received more than $12 million from the Canada Foundation for Innovation (CFI) and the Quebec government to boost the performance of its infrared lasers. This co-funding will allow INRS research members to remain leaders in this strategic field for the future.
Ultimately, this extensive work will provide better access to even more efficient facilities, which are unique in Canada. Operating this variety of high-intensity lasers, including the most powerful laser in the country, allows for numerous applications, whether in basic research (probing and controlling matter) or applied research (high-resolution imaging with medical and environmental applications). Moreover, the ALLS laboratory offers unique too

Credit: Illustration: Yen Strandqvist/Chalmers University of Technology There are high hopes for the next generation of high energy-density lithium metal batteries, but before they can be used in our vehicles, there are crucial problems to solve. An international research team led by Chalmers University of Technology, Sweden, has now developed concrete guidelines for how the batteries should be charged and operated, maximising efficiency while minimising the risk of short circuits.
