Unraveling anisotropic and pulsating etching of ZnO nanorods in hydrochloric acid via correlative electron microscopy

By

An additional Friday publication update! Controlled etching behavior is extremely important to be able to create crystal solids with defined structures and functions. In this newest publication, in situ liquid cell transmission electron microscopy was used to oberserve the dynamic behavior during the pencil shape evolution of a single crystal ZnO nanorod in aqueous hydrochloric … Read More

Formation mechanism of high-index faceted Pt-Bi alloy nanoparticles by evaporation induced growth from metal salts

By

Tuesday publication update! Are you interested in doing catalysis in which you can actually see your reaction happening on the nanoscale? Researchers at the Northwestern University have recently published in Nature Communications using the Atmosphere AX system, including our machine vision software AXON. They looked at the coalescence and growth of these high-index-facet Pt-Bi nanoparticles … Read More

Atomistic Insights into the Nucleation and Growth of Platinum on Palladium Nanocrystals

By

Additional Friday publication update! In this Nature Communications publication, in situ liquid-cell transmission electron microscopy, using the #PoseidonAX, was used to find the atomistic details during the nucleation and growth of Pd@Pt nanocubes. Various parameters were investigated, such as colloidal capping agents and the precursor concentration. Obtaining atomistic real-time information on the growth of colloids … Read More

Metastable Hexagonal Close-Packed Palladium Hydride in Liquid Cell Transmission Electron Microscopy

By

New Tuesday publication! In this publication featured in Nature, our #PoseidonSelect was used to look at crystals grown from high-energy precursors. Most of the time, these adopt metastable structures depending on the initial conditions, such as temperature, pressure or crystal size. With the unique environment created in the liquid cell, the formation of a hcp … Read More

Preparation of High-Quality Sample for MEMS-Based In-Situ (S)TEM Experiments

By

Tuesday publication update! Congratulations to @Vesna from the university of Stuttgart on publishing this nice work showing a new methodology for the preparation of focussed ion beam (FIB) lamella for in-situ microscopy. Additionally, they investigated what the influence of the beam was on the electrical and electro-thermal measurements. Furthermore, thinning of the whole lamella or … Read More

Quantitative In Situ Visualization of Thermal Effects on the Formation of Gold Nanocrystals in Solution

By

An additional Friday publication update! Researchers from Paris have recently published a beautiful #PoseidonSelect heating experiment on the growth of gold nanoparticles. The nanoparticles were grown at room temperatur and elevated temperatures, showing temperature dependent nanoparticle growth. Visualizing these thermal effects at the single nanoparticle level reveals how the competition between the growth speed and … Read More

Identification of Nanoscale Processes Associated with the Disorder-to-Order Transformation of Carbon-Supported Alloy Nanoparticles

By
