EPJ ST Highlight - How can x-ray diffraction be used for a reliable study of nanostructured materials?
- Details
- Published on 13 June 2022
A new overview shows how x-ray diffraction can effectively measure lattice defects responsible for the unique properties of nanostructured materials – but special care is required for the application
Owing to their unique physical properties, nanostructured materials are now at the forefront of materials science. Several different techniques can be used to characterise their microscopic features, but each of these has its pros and cons. In new research published in EPJ ST, Jenő Gubicza at ELTE Eötvös Loránd University, Budapest, shows that one indirect method, named x-ray diffraction line profile analysis (XLPA) is suitable for analysing nanostructured materials, but its application and interpretation require special care for obtaining reliable conclusions.
EPJ ST Highlight - Energy harvesting to power the Internet of Things
- Details
- Published on 09 June 2022
A new paper in EPJ Special Topics shows how energy can be harvested from vibrating micromagnets to power the now ubiquitous wireless sensors in the most efficient way.
The wireless interconnection of everyday objects known as the Internet of Things depends on wireless sensor networks that need a low but constant supply of electrical energy. This can be provided by electromagnetic energy harvesters that generate electricity directly from the environment. Lise-Marie Lacroix from the Université de Toulouse, France, with colleagues from Toulouse, Grenoble and Atlanta, Georgia, USA, has used a mathematical technique, finite element simulation, to optimise the design of one such energy harvester so that it generates electricity as efficiently as possible. This work has now been published in EPJ ST.
EPJ ST: Denis Machon new Editor on board

The publishers of The European Physical Journal Special Topics are pleased to announce the appointment of Dr. Denis Machon as new Editor in the board.
Denis Machon completed his PhD at the age of 26 from Grenoble INP and his postdoctoral studies from University College of London. During these years, he worked on pressure-induced amorphization and polyamorphism, both on the experimental and theoretical aspects. As a professor assistant at University Lyon 1, his research interests were centered on high-pressure physics, thermodynamics and phase transitions. His main research activities were devoted to understanding of the combined effects of pressure, size and interface in the phase stability. In 2017, he joined as associated professor the “Laboratoire Nanotechnologies et Nanosystèmes” (LN2), a joint International Research Laboratory co-operated in Canada by “Université de Sherbrooke” and in France by CNRS. At LN2, he works on mesoporous silicon and germanium as anode materials for Li-ion batteries.
He co-authored more than 90 papers and book chapters.
EPJ ST Highlight - Using AI to expand the quality and fairness of urban data
- Details
- Published on 11 April 2022
The sparse and inconsistent availability of urban data is currently hampering efforts to manage our cities fairly and effectively – but this could be solved by exploiting the latest advances in artificial intelligence.
Our cities are remarkably complex systems. Every day, they host countless numbers of interconnected exchanges between people and processes, generating vast amounts of data in turn. Researchers have begun to explore how this information could be used to improve urban environments – but due to limitations in its quality, these efforts continue to face significant challenges. Through detailed analysis published in EPJ ST, Bill Howe and colleagues at the University of Washington, USA, propose how artificial intelligence (AI) could be used to expand the coverage, access, and fairness of data collected in cities.
EPJ ST Highlight - An overview of neutrinos and their interactions
- Details
- Published on 18 February 2022
A new summary of the study of neutrinos, and the ways in which they interact with regular matter, could inspire both new and senior neutrino researchers to open up new areas of investigation within the field.
The history of our understanding of neutrinos, from their astrophysical origins to their elusive interactions with matter, is full of surprises. Although we know that they are the second most abundant particles in the universe after photons, they are also the least well understood. In this special issue of EPJ ST, M. Sajjad Athar and S.K. Singh at Aligarh Muslim University present a short overview of the study of neutrinos, and the ways in which they interact with other forms of matter at mid-to-high energies.

EPJ ST Highlight - Examining recent developments in Quantum Chromodynamics
- Details
- Published on 14 December 2021
The strong nuclear force is responsible for binding together quarks, the basic building blocks of protons and neutrons, that comprise almost all of the visible matter. A new collection looks at recent development in the field of Quantum Chromodynamics (QCD) from a range of perspectives.
Created as an analogy for Quantum Electrodynamics (QED) — which describes the interactions due to the electromagnetic force carried by photons — Quantum Chromodynamics (QCD) is the theory of physics that explains the interactions mediated by the strong force — one of the four fundamental forces of nature.
A new collection of papers published in EPJ Special Topics, and edited by Diogo Boito, Instituto de Fisica de Sao Carlos, Universidade de Sao Paulo, Brazil, and Irinel Caprini, Horia Hulubei National Institute for Physics and Nuclear Engineering, Bucharest, Romania, brings together recent developments in the investigation of QCD.
EPJ ST Highlight - An exploration of tipping in complex systems
- Details
- Published on 22 November 2021
This special issue examines the extensive landscape of research into tipping within complex systems, and provides guidance as to where the field will likely be headed in the future.
Complex systems can be found in a diverse array of real-world scenarios, but are unified by their ability to suddenly transition between drastically different patterns of behaviour. Known as ‘tipping,’ this type of transformation is generally triggered by small changes in the parameters of individual systems – whose effects can rapidly cascade to alter entire networks of interacting subsystems. This special issue of EPJ Special Topics explores the nature of tipping in complex systems through 21 new articles. Together, the studies reveal recent trends and directions of research within the field, and highlight the pressing challenges it will face in the future.
