Progress and prospects in nonlinear extreme-ultraviolet and X-ray optics and spectroscopy

Majed Chergui

Free-electron lasers and high-harmonic-generation table-top systems are new sources of extreme-ultraviolet to hard X-ray photons, providing ultrashort pulses that are intense, coherent and tunable. They are enabling a broad range of nonlinear optical and s ...

SYNAPSE: An international roadmap to large brain imaging

Giorgio Margaritondo

Since 2020, synchrotron radiation facilities in several Asia-Pacific countries have been collaborating in a major project called "SYNAPSE"(Synchrotrons for Neuroscience: an Asia-Pacific Scientific Enterprise). They use x-ray imaging to attack in a coordina ...

Synchrotron Radiation and Sensors: A History of Synergies

Giorgio Margaritondo

Synchrotron radiation has emerged over more than one-half century as a gigantic worldwide enterprise involving tens of thousands of researchers. Its history has been continuously and strongly linked to the technical progress of sensors. We review here diff ...

Operando X-ray diffraction during laser 3D printing: from machine design to experiments and computer simulations

Samy Hocine

The importance of additive manufacturing, also known as 3D printing, has grown exponentially in the recent years thanks to its high flexibility to manufacture intricate parts. This process can be divided into many different sub-categories, depending on the ...

Rapid Elastic Contact: Image Processing and the Virtual Frame Technique (VFT)

Siqi Zheng

A central air bubble is observed to be maintained during the process of an elastic hemi-sphere impacting on a smooth rigid surface. The similar phenomenon has been found in droplet impact in other studies. The effect of air gap between the two solids has b ...

Clusters and Nanocrystals

Christoph Bostedt, Daniela Rupp

Clusters and nanocrystals constitute intermediates between molecules and condensed matter. Due to their finite size, clusters have a wide spectrum of applications ranging from building blocks for novel materials to model systems for fundamental investigati ...

Perspective: Opportunities for ultrafast science at SwissFEL

Majed Chergui, Paul Beaud

We present the main specifications of the newly constructed Swiss Free Electron Laser, SwissFEL, and explore its potential impact on ultrafast science. In light of recent achievements at current X-ray free electron lasers, we discuss the potential territor ...

Stable Transitions from Free-space to Contact: A Dynamical System Based Approach

Aude Billard, Seyed Sina Mirrazavi Salehian

In this work, we propose a dynamical system based strategy for establishing a stable contact with convex shaped surfaces during non-contact/contact scenarios. A contact is called stable if the impact occurs only once and the robot remains in contact with t ...

Synchrotron light: A success story over six decades

Giorgio Margaritondo

Synchrotron radiation research continues to be a major factor in the progress of science and technology, as it has been for more than half a century. We present different aspects of its history, starting with an unconventional approach: a fictional version ...
