💭 Curious what insights you can unravel when combining in situ liquid cell microscopy with 4D scanning transmission electron microscopy (4D-STEM)? 💧 Then make sure to join us in our upcoming online webinar on March 27th with Dr. Christian Liebscher from the Max-Planck-Institut für Eisenforschung GmbH! During this webinar, Dr. Liebscher will detail how he and his team were able to explore the evolution and oxidation of nanostructured copper by integrating in situ electrochemical liquid phase (ELP) microscopy and 4D-STEM. Noteably, these in situ experiments were performed using the DENSsolutions Stream system, which enables complete flow control, and does not require the removal of the liquid for further data acquisition. Together, we will delve into how the application of 4D-STEM, where a nanobeam electron diffraction pattern is obtained at each probe position, offers insights beyond the mere shape and morphology of the nanocatalyst. Moreover, during this webinar, Dr. Liebscher will elaborate on strategies for analyzing the complex multidimensional datasets and discuss current limitations and opportunities associated with coupling in situ ELP microscopy with 4D-STEM.

Lateral resolution-sensitivity comparison of different analytical techniques Energy dispersive X-ray spectroscopy (EDS) in combination to a dual beam focused ion beam/ secondary electron microscopy (FIB-SEM) is a standard technique for element imaging. Though, this technique has some difficulties to detect light elements because of the low energy and the high absorption probability of the emitted X-ray which makes it not adequate for extensive analysis of e.g. Li ions. The following graph in Figure 5 is a resolution-sensitivity landscape showing the measurement capabilities of a multitude of analytical techniques. Improvements in the brightness of the FIB sources allows to address higher spatial resolutions than are historically associated with dynamic SIMS. FIB-SIMS is placed somewhere between STEM/EDS and dynamic SIMS, reaching detection limits down to the ppm and spatial resolution below 50 nm. #Eurofins | EAG Laboratories

Discover our latest study, published in ACS Nano, delving into the world of Monolayer MoS2 Field-Effect Transistors. As we push the boundaries of technology, implementing 2D materials in FETs emerges as a promising avenue for advancement along the tech roadmap. Our study focuses on the critical aspect of defect assessment, directly examining the regions that hinder device performance. Our findings illuminate direct defect assessment via in situ scanning probe microscopy, providing invaluable insights into optimizing device performance by discerning the impact of grain boundaries, bilayer islands, and defective grain domains on channel conductance.

I'm thrilled to share that my latest publication, "Nanoscale Chemical Probing of Metal-Supported Ultrathin Ferrous Oxide via Tip-Enhanced Raman Spectroscopy and Scanning Tunneling Microscopy," has just been published as cover art in Chemical & Biomedical Imaging. Ultrathin ferrous oxide (FeO) has been gaining attention for its high catalysis activities and economic efficiency. However, to design better iron oxide-based nano devices, it's essential to understand the interfacial properties of FeO. Unfortunately, chemical probing of these properties at the nanoscale has been challenging as it needs to characterize localized chemical information with nanoscale precision. In this study, we present a nanoscale chemical probing of FeO using a combination of scanning tunneling microscopy (STM) and tip-enhanced Raman spectroscopy (TERS). Our results show that the symmetry of Au surfaces has minimal impact on the structure of FeO films. Additionally, we observed a unique wrinkled FeO structure on FeO/Au(100).
