A side view of the LHCb detector

In ten years of operation the LHCb experiment has probed the nature of physics attempting to answer some of the Universe’s most fundamental questions. A new review examines its past achievements and future potential.

A new review published in EPJ H by Clara Matteuzzi, Research Director at the National Institute for Nuclear Physics (INFN) and former tenured professor at the University of Milan, and her colleagues, examines almost three decades of the LHCb experiment – from its conception to operation at the Large Hadron Collider (LHC) – documenting its achievements and future potential.

EPJ H Highlight - Tracking the progress of fusion power through 60 years of neutral particle analysis

The Alpha Plasma Machine: a prototype of tokamaks that in the future will provide the world with clean nuclear fusion energy

Harnessing the fusion power of the stars requires the control of plasma and a powerful diagnostic tool to analyse it

As the world’s energy demands grow, so too does growing concern over the environmental impact of power production. The need for a safe, clean, and reliable energy source has never been clearer. Fusion power could fulfil such a need. A review paper published in EPJ H examines the 6-decade history of neutral particle analysis (NPA), developed in Ioffe Institute, Saint Petersburg, Russia, a vital diagnostic tool used in magnetic plasma confinement devices such as tokamaks that will house the nuclear fusion process and generate the clean energy of the future.

EPJ E Highlight - Micro-environmental influences on artificial micromotors

Janus particles propel themselves forward

New experiments reveal the characteristic ways in which self-propelled ‘Janus particles’ with charged coatings will slide across or move away from charged boundaries in their surrounding environments.

By harvesting energy from their surrounding environments, particles named ‘artificial micromotors’ can propel themselves in specific directions when placed in aqueous solutions. In current research, a popular choice of micromotor is the spherical ‘Janus particle’ – featuring two distinct sides with different physical properties. Until now, however, few studies have explored how these particles interact with other objects in their surrounding microenvironments. In an experiment detailed in EPJ E, researchers in Germany and The Netherlands, led by Larysa Baraban at Helmholtz-Zentrum Dresden-Rossendorf, show for the first time how the velocities of Janus particles relate to the physical properties of nearby barriers.
