BAMline—A real-life sample materials research beamline

Abstract

With increasing demand and environmental concerns, researchers are exploring new materials that can perform as well or better than traditional materials while reducing environmental impact. The BAMline, a real-life sample materials research beamline, provides unique insights into materials’ electronic and chemical structure at different time and length scales. The beamline specializes in x-ray absorption spectroscopy, x-ray fluorescence spectroscopy, and tomography experiments. This enables real-time optimization of material properties and performance for various applications, such as energy transfer, energy storage, catalysis, and corrosion resistance. This paper gives an overview of the analytical methods and sample environments of the BAMline, which cover non-destructive testing experiments in materials science, chemistry, biology, medicine, and cultural heritage. We also present our own synthesis methods, processes, and equipment developed specifically for the BAMline, and we give examples of synthesized materials and their potential applications. Finally, this article discusses the future perspectives of the BAMline and its potential for further advances in sustainable materials research.

Time-, space- and energy-resolved in situ characterization of catalysts by X-ray absorption spectroscopy

“…Experiments were performed at the BAMline at the BESSY-II storage ring (Helmholtz-Zentrum Berlin fu ¨r Materialien und Energie, HZB). 18 We thank the HZB for the allocation of synchrotron radiation beamtime.…”

“…15,16 With dispersive XAS the advantage for characterizing catalysts at work is that the whole energy range interacts with the sample and, with our setup, a large beam of a few mm 2 allows the extraction of time-, space-and energy-resolved information in a scanningless mode. 17,18 One particular catalytic conversion where in situ analysis is of special interest is methane dehydroaromatization (MDA). 19 This reaction allows the production of ethylene, light aromatics and hydrogen at high temperatures (Z600 1C) in the absence of oxidants.…”

Effects of Ligand Substituents on the Character of Zn-Coordination in Zeolitic Imidazolate Frameworks

“…X-ray absorption near edge structure spectroscopy (XANES) measurements were performed at the BAMline (BESSY-II, Helmholtz Centre Berlin for Materials and Energy Berlin, Germany). 57 The beam was monochromatized using a double-crystal monochromator (DCM) with a Si crystal with [111] orientation. The size of the beam was 3 mm (h) × 1 mm (v).…”

Phase stability studies on transition metal phosphates aided by an automated synthesis

“…To evaluate and compare the metal coordination environments in different phases obtained through synthesis, XANES (near-edge X-ray absorption fine structure) and EXAFS (extended X-ray absorption fine-structure) spectroscopy measurements were performed at the BAM line (BESSY-II, Helmholtz Centre Berlin for Materials and Energy Berlin, Germany). 40…”
