Quantum mechanics is one of the central pillars of modern physics. This mathematically complex theory which allows the properties and laws of matter to be described is, however, rather to understand intuitively. Generations of young scientists have approached this difficult concept with the help of double-slit experiments that clearly demonstrate wave – particle duality. Two new videos from the Jülich Centre for Neutron Science (JCNS) offer a practical alternative to this.

The videos clarify fundamental aspects of quantum mechanics using neutron scattering experiments from research undertaken at the Jülich institute. The videos are around 5 and 4 minutes in length respectively, and are appropriate for use in an introductory lecture course in quantum mechanics or for self-study purposes.

We invite former doctoral students to write a blog post about their dissertation and their time at Forschungszentrum Jülich. Today, we are pleased to present a guest contribution by Dr. Siaufung Dang. #MyPhD

BildIn my PhD thesis I have focused on ab initio calculations to derive key properties of intercalation compounds for lithium ion batteries. In this respect I have been working on LixCoO2 and LixMg2Si which are both solid solutions within a defined compositional range. Key properties include the intercalation voltage, structural features and thermodynamic properties.

Battery technology penetrating many areas of industry and everyday life is a field with great impact on the development and the sustainability of our society. However, ab initio methods still belong to a field dominated by theorists and should be promoted to be more accepted in applied sciences. The employment of ab initio calculations in an “intelligent materials design” fashion is expected to continuously gain importance in the next years and decades. Therefore, it is imperative not to miss the point of opportunity to reinforce the activities regarding the utilization of ab initio methods on real materials in high-tech applications such as batteries.

Jülich Blogs is the blog platform of Forschungszentrum Jülich, one of the largest research centres in Europe. In addition to the company website, which provides information in a neutral manner at www.fz-juelich.de, our blog entries are full of colourful and enthusiastic first-hand information: scientists, PhD students, and employees of Forschungszentrum Jülich write about their work as well as challenges and successes in their laboratories, and grant personal insights to Jülich research.
