Nanoporous gold (NPG) is characterized by a bicontinuous network of nanometer-sized
metallic struts and interconnected pores formed spontaneously by oxidative dissolution of …

Solid catalysts are the workhorses that convert feedstock molecules into fuels, chemicals
and materials. Solid catalysts are highly complex, porous, multi-elemental and often …

Understanding morphological changes of nanoparticles in solution is essential to tailor the
functionality of devices used in energy generation and storage. However, we lack …

The synthesis of hierarchically porous materials usually requires complex experimental
procedures, often based around extensive trial and error approaches. One common …

Liquid metal dealloying is a promising technique for synthesizing non-noble porous
materials by preventing oxidation in a metallic melt. This method considers the heats of …

Ptychographic X-ray microscopy is an ideal tool to observe chemical processes under in situ
conditions. Chemical reactors, however, are often thicker than the depth of field, limiting the …

Tomographic imaging of catalysts allows non‐invasive investigation of structural features
and chemical properties by combining large fields of view, high spatial resolution, and the …

The quest for understanding the structural mechanisms of material properties and biological
cell functions has led to the active development of coherent diffraction imaging (CDI) and its …

Nanoporous gold (NPG), formed by the chemical or electrochemical dealloying of binary or
ternary solid solutions, has strong prospects as a catalyst, sensor substrate, membrane …

Two in situnanoreactors' for high-resolution imaging of catalysts have been designed and
applied at the hard X-ray nanoprobe endstation at beamline P06 of the PETRA III …
