An additional Friday publication update! 📖 In this work, silver−gold (Ag−Au) alloyed nanocages were used as a model system to understand the changes in wall thickness of the nanocages as a function of temperature using our #FusionSelect in-situ holder. Using different temperatures and various wall-thicknesses, the stability of the nanocages was investigated. By thickening the walls of the cages, the stability could be greatly enhanced, which in turn can inspire future fundamental and applied research.Read the full publication here:https://lnkd.in/g9_rSiJQ |

Tuesday publication update! 📖 The shape of any nanoparticle also influence their reactivity by exposing different crystal facets. This is why having control over the shape and size is of importance. In this newest publication, the changes of individual surface-exposed facets during diverse shape transformations of Au nanocrystals using liquid phase TEM in various chemical potentials and kinetic Monte Carlo simulations were investigated using our #PoseidonSelect system. The results show that diffusion of surface atoms heavily contribute to the final structure in Au nanocrystal transformation which can in turn help gain control over the synthesis of the size and shape of the particles.Have you become curious?

Tuesday publication update! 📖 Grab a cup of coffee and go read this publication! Magnesium nanoparticles (NPs) have not been researched much in their role as energetic materials due to the lack of facile, scalable synthesis methods. Using the #FusionSelect for in situ heating electron microscopy experiments, combined with time-of-flight mass spectrometry (T-jump/TOFMS) at high heating rates, energy release mechanisms within oxidative environments could be studied for these specific materials. With the help of this work, new designs for magnesium based nanoenergetic materials can be obtained to use in tunable energy release materials.Want to learn more?https://lnkd.in/gmbMCdws |

Tuesday publication update! 📖 Carbon dioxide electroreduction facilitates the sustainable synthesis of fuels and chemicals. To understand more about carbon dioxide reduction, identifying active sites of high-performance Cu nanocatalysts is necessary. In this publication, @Yao Yang, from the university of Berkeley, uses the #PoseidonSelect and 4D-STEM to show the electrochemical reaction with Cu nanoparticles. The correlation of multimodal operando techniques serves as a powerful platform to advance our fundamental understanding of the complex structural evolution of nanocatalysts under electrochemical conditions. The monodisperse Cu NPs undergo structural transformations where the surface oxide is reduced, followed by aggregation.Interested in the paper?Read it here!https://lnkd.in/d5BarD5Y |

Tuesday publication update! 📖 In this publication, the group of @Ovidiu Ersen has worked hard in observing copper-based nanoparticles for catalysis using the #Atmosphere gas cell holder. Even though copper nanoparticles are used broadly in industrial applications, the fundamental understanding of oxidation and reduction of these nanoparticles is still a matter of debate. The goal of this research if to study Co catalysts under industrial relevant pressures to observe their morphological changes during redox reactions. This study offers insights into the mobility of the copper phase during its oxidation–reduction process.Want to learn more?https://lnkd.in/gfNAtnRG |

An additional Friday publication update! 📖 Are you curious about nanoparticle morphological changes during reduction in catalysis? In this newest publication from #UtrechtUniversity, Savannah Turner from the group of Krijn de Jong uses the #Atmosphere gas cell system to investigate the preparation of supported metal catalysts. Obtaining insight in the growth and reduction of nanoparticles is highly valuable in the field of catalysis. In this paper, ex situ and in situ results are investigated to show the growth of individual nickel nanoparticles from phyllosilicates during reduction under atmospheric pressure. Using careful considerations, dose effects were excluded, which is highly important for any in situ experiment.

Tuesday publication update! 📖 In this work the in situ growth of diphenylalanine nanotubes was examined via liquid-cell transmission electron microscopy. These type of fibers are interesting as they are associated with the development of neurological diseases including Alzheimer’s disease and type II diabetes. Using the #PoseidonAX system, the kinetics, dynamics, structure formation, and assembly mechanism of these supramolecular assemblies were monitored. The electron dose was extremely important in these measurements, as a high electron flux drove a breakdown of the diphenylalanine. In the end, this study shows that LCTEM can be a useful tool for studying the self-assembly and dynamics of wide range of soft materials and biological systems.Want to know more?Read the full paper here:https://lnkd.in/g4873SZy |

Tuesday publication update! 📖 CO oxidation is one of the most important heterogeneous catalytic reactions. Catalysts that perform CO oxidation are sensitive for changes in their activity based on their structure. In this publication, the structure activity relationship of silica-supported Au-based bimetallic nanocatalysts was investigated using the #FusionAX in an environmental electron microscope for CO oxidation. It was found that CuOx/Au heterostructure are formed, which enhancement of catalytic activity. The results in this paper provide a different perspective in understanding the electronic metal–oxide interaction in AuCu/SiO2 nanocatalysts.Are you interested in reading more?Go and read the full paper:https://lnkd.in/gtHQbBZ2 |

Tuesday publication update! 📖 Have you ever seen nanoparticles being exsolved from a perovskite surface? If not, you can observe this in this newest publication using the #FusionAX! Authors from several universities provided insight into Ir nanoparticle exsolution from a SrTiO3 host oxide lattice. Instead of a conventional synthesis “top-down” method, in this case the catalytic metal is incorporated as an ion in an oxide support during synthesis, to then diffuse to the host surface when the material is heat treated. By using exsolution, Ir nanoparticles were formed which provided a theoretical platform and practical recommendations to further the development of highly functional and broadly applicable exsolvable materials.Want to read more?https://lnkd.in/g2wHmkjg |

Tuesday publication update! 📖 Have you ever seen nanowires grow in real time? The authors from the Philipps-Universität Marburg in the group of @Kerstin Volz have recently published a very nice showcase of GaP nanowires grown via the VLS mechanism. During the growth, the nanowires change their direction randomly, producing kinks and angles with specific dominant values. These defect and growth understandings can finally lead to an increased control of their size and shape, which is a large step forward in research on applicable nanowire devices.Want to read the publication?https://lnkd.in/gHJMqsvs |
