The Helmholtz Center Berlin (HZB) and the Max-Planck Society (MPG) strengthen their research in renewable energies with the implementation of the joint Energy Material in-Situ Lab Berlin (EMIL) at the third generation light source BESSY II. The new facility is dedicated to the in-situ and in-system x-ray analysis of materials and devices for photovoltaic applications, (photo-) catalytic processes, energie conversion and storage. To obtain a comprehensive understanding of the involved materials, spectroscopic methods with x-rays from the soft-up to the hard xray regime reveal an almost complete picture of their chemical and electronic properties. The contribution presents the layout of the x-ray beamlines and their performance in terms of photon flux, energy resolution and spot sizes.

The measures of democracy commonly used in empirical research suffer notable limitations, primarily the exclusion of participation. As a result, quantitative studies may undervalue the effect of democracy on important social outcomes or misinterpret the aspect of democracy responsible for that effect. We respond by introducing and validating two variants of a new indicator, the Participation Enhanced Polity Score (PEPS), which augments institutional factors with the breadth of citizen parBruce E.
