Growth of organic nanocrystals revealed
Crystals are not necessarily hard and resistant but also occur in soft matter when weakly bound molecules arrange in a regular order. Such organic crystals are widespread in pharmaceuticals products, but also occur as tiny nanocrystals in the active layer of organic solar cells. Here, the organic nanocrystals constitute the key ingredient for conversion of […]

Nano-tomography elucidate internal structural order in MOF superaparticles
Emerging functional materials for applications in photonics, plasmonics, and mechanics can be created by assembling smaller particles into defined structures. Among various assembly strategies, spherical confinement (e.g. in drying emulsion droplets) to guide the self-assembly process is gaining increasing interest. This hierarchical approach allows for the assembly of a finite number of particles into a […]Emerging functional materials for applications in photonics, plasmonics, and mechanics can be created by assembling smaller particles into defined structures.

Sub-Kelvin precision in situ thermometry achieved in gas cells
In situ TEM investigations in environmental conditions are a powerful approach to analyze materials for catalysis, especially if you utilize dedicated MEMS heating systems to operate at elevated temperatures. However, how can we be certain that the heating devices achieve the required temperature at the spot of observation? In situ thermometry provides an answer. In […]

Structure and properties of supersaturated Ni-Au nanoparticles revealed by GRK and IMN researchers
In a joint effort across 4 GRK subprojects involving 10 GRK members, CENEM’s strength of combining different (scattering) probes revealed fascinating structural, chemical as well as mechanical properties of supersaturated and highly faceted Ni-Au nanoparticles equilibrated by solid-state dewetting on sapphire. The results, which were recently published in Acta Materialia (https://doi.org/10.1016/j.actamat.2021.117318), include the impact of […]In a joint effort across 4 GRK subprojects involving 10 GRK members, CENEM’s strength of combining different (scattering) probes revealed fascinating structural, chemical as well as mechanical properties of supersaturated and highly faceted Ni-Au nanoparticles equilibrated by solid-state dewetting on sapphire.

Structural insight into hydrogenated TiO2, a sustainable and noble metal free approach for photocatalysis
Our work entitled “Hydrogenated Anatase TiO2 Single Crystals: Defects Formation and Structural Changes as Microscopic Origin for Co-Catalyst Free Photocatalytic H2 Evolution Activity” was just published in the Journal of Materials Chemistry A (DOI: 10.1039/D1TA04809K). The photocatalytic activity trend of the anatase epilayers is similar to that of anatase powders and brookite single crystals, the […]Our work entitled “Hydrogenated Anatase TiO2 Single Crystals: Defects Formation and Structural Changes as Microscopic Origin for Co-Catalyst Free Photocatalytic H2 Evolution Activity” was just published in the Journal of Materials Chemistry A (DOI: 10.1039/D1TA04809K).
