Have you ever wanted to look at atomic resolution images of phase transformations in the TEM? This paper shows in situ atomic-resolution scanning transmission electron microscopy using our #FusionAX system, in a Pt−Sn system. Heating the sample up showed showing the initial stages of the PtSn4 to PtSn2 phase transitions. In the video you can … Read More
In this recent publication, the authors have used liquid phase electron microscopy to observe the dynamic behavior of geothite during dissolution under the irradiation of the electron beam. Kinetic simulations of the different radiolysis species provides insight into the redox and acidity of the liquid during the exposure to the beam. These interactions are very … Read More
Have you ever thought on looking at sublimation reactions on the nanoscale, in real time? These authors from the university of Leoben looked at nanoalloying Al–Cu nanoparticles in situ within a transmission electron microscope using the #FusionAX system. The results showed that Au nanoparticles and Cu nanowires can undergo melting and alloying on an Al … Read More
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
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
Tuesday publication update! Have you ever thought about using a liquid cell for a vapor phase microscopy experiment? This new publication has! @Taylor Woehl at the University of Maryland has investigated the nucleation, growth, and evaporation of nanoscale sessile drops using vapor phase TEM (VPTEM) with the #PoseidonSelect. Nanoscale water condensation dynamics in strong electric … Read More
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
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
Another Friday publication update! In this study the goal was to establish a systematic understanding of the phase evolution in a face centered cubic non equiatomic nanocrystalline compositionally complex alloys. The #FusionSelect was used to heat the sample, while forming automated crystal orientation maps at the same time. This gave detailed information on the decomposition … Read More
Friday publication update! In this recent publication, the role of metal vacancies was discovered in InGaN quantum wells, using the #Atmosphere system. Using focussed ion beam (FIB) preparation methods, a MOVPE nanoreactor was added to the #Gascell system and investigated for void formation, in situ. Metal vacancy agglomeration was a crucial part of the formation … Read More
