Neutrons are a unique and essential probe of materials, interacting with nuclei rather than electrons, except in magnetic systems. Through a range of experimental techniques and the associated instrumentation, neutrons cover about ten decades in length scale and a similar extent in time scale, affording an almost unlimited field of applications in condensed matter science and nuclear and...
Heterogeneous catalysis plays a pivotal role in the chemical manufacturing sector. Efficient catalyst design enables reactions to be performed at large-scale and for extended periods of time. Typically, product selectivity is a primary design parameter, with waste minimisation central to the economic viability of the commercial process. Historically, the implementation of heterogeneous...
Neutron scattering techniques are a powerful tool in life science research. The lack of ionizing radiation damage and the ability to use hydrogen isotope labelling & contrast make neutrons uniquely suited for the study of biological materials. With improving neutron instruments and an increasing number that are well-suited to the study of biomolecules, the expectation is that this community...
Electric vehicles are on the way to replace gasoline-powered vehicles n our near future. To power such vehicles, Li-ion batteries with very high storage capacities are necessary, so that these cars travel sufficiently large distances before needing a recharge at charging stations. Moreover, these batteries should have long lifetimes so that they can be charged and discharged several times...
Neutron scattering is a unique technique in magnetism and for correlated electron systems, since it measures directly the Fourier transform of the time-dependent magnetic pair correlations. We give a very brief introduction to magnetic neutron scattering and try to highlight the specificities of this technique with respect to other experimental magnetic probes, such as the unique kinematic...
Owing to their zero net charge neutrons are able to pass through thick layers of matter (typically several centimetres), but are sensitive to magnetic fields due to their intrinsic magnetic moment. Therefore, in addition to the conventional attenuation contrast image, the magnetic field inside and around a sample can be visualized independently by detection of polarization changes in the...
A movement of water through plants has been the focus of scientific investigation for over 250 years. Recent developments(2008-2022) of neutron imaging in the field of in vivo plant have advanced to the point of near real-time visualization of water transport both through the rhizosphere and the xylem system of plants. In this workshop, the related research will be reviewed and looked at terms...
Due to the high penetration depth and large beam cross section of neutrons and the existence of advanced sample environments, neutron methods have received great attention as a suitable probe in the study of engineered materials, especially metals. This contribution focuses on examples of how neutrons have a great impact to solve open questions in industrial challenges. Examples as pipeline...

As a structural geologist, Dr Walter deals with (quantitative) microstructure analysis, the mechanisms and processes of rock deformation and recrystallization. In recent years Jens have been in charge of the realization of sample environments for deformation and recrystallization experiments in the neutron beam. This makes it possible to quantitatively determine deformation or...
Porous materials (Macro-, Meso- & Micro- porous systems) form a large family englobing as different systems as amorphous carbons, semi-ordered MCM silicas and fully crystalline Metal Organic Frameworks (MOFs). All these compounds find their attractivity as solid host media where guest species can travel through, be trapped or be converted.This give rise to their present uses as molecular...
The use of X-rays is always first choice because of easy availability and low cost - but when X-rays fail, there is a high probability that problems can be solved with neutron imaging, especially in archaeology and paleontology, where different fossilasion conditions render different contrasts for neutrons. The talk will give an overview about the examination of fossils embedded in 'red...
