S15 from Marc Brunet Cabré et al 2024 “Carbon Thin-Film Electrodes as High-Performing Substrates for Correlative Single Entity Electrochemistry” SI-5: Morphology of isolated MXene (Ti3C2Tx) on anC by AFM Figure S15: AFM images of two different regions of anC substrate with dropcasted MXene flakes. (A) Displays an isolated flake on anC and (B) displays multiple flakes which present partial stacking between them. NANOSENSORS PointProbe® Plus PPP-NCHR AFM probes were used for the scanning probe microscopy (SPM) characterization in non-contact mode.

Single-entity electrochemistry (SEE) is an emerging area of research that aims at evaluating the electrochemical response of materials at the micro- and nanoscale. * Several… Read More »Carbon Thin-Film Electrodes as High-Performing Substrates for Correlative Single Entity Electrochemistry

20 bromine atoms positioned on a sodium chloride surface using the tip of an atomic force microscope at room temperature, creating a Swiss cross with the size of 5.6nm. The structure is stable at room temperature and was achieved by exchanging chlorine with bromine atoms. (Fig: University of Basel, Department of Physics) The image was taken using a NANOSENSORS PointProbePlus PPP-NCL AFM probe

Science & Technology

Model for the graphite electrode Interface analysis between a model for the graphite electrode and solvent for electrolytes of lithium-ion batteries. An example of the interface observation between highly oriented pyrolytic graphite (HOPG) as a model for graphite electrodes and tetraglyme, which has been studied as a solvent of electrolytes for lithium ion batteries. The AFM cantilever oscillation frequency and amplitude during the experiments were 92 kHz and 0.3 nm, respectively. The temperature was maintained at 298 K under an argon atmosphere throughout the experiment to prevent the dissolution of contaminants from the air, which could affect the interface structure. The topographic image revealed an ordered structure at Δf = 1000 Hz, obtained with tetraglyme adsorbed on an HOPG surface. Scanned with a NANOSENSORS PPP-NCHAuD AFM probe in a Shimadzu SPM-8000FM AFM system in FM mode.

Effective Solid Electrolyte Interphase Formation on Lithium Metal Anodes by Mechanochemical Modification

Figure 6. from Julia Wellmann et al. “Effective Solid Electrolyte Interphase Formation on Lithium Metal Anodes by Mechanochemical Modification”: SEM images of lithium electrodes after cycling in symmetric Li∥Li cells with liquid carbonate-based electrolytes (1 M LiPF6 in EC:EMC (3:7)) (a, f) without modification, (b, g) after mechanical modification, (c, h) after mechanochemical modification, and (d, i) after roll-pressing and immersion for 1 day and (e, j) for 7 days after (a–e) one electrodeposition step (1 mAh, 1 mA cm–2) and (f–j) after 50 cycles (1 mAh, 1 mA cm–2). AFM topography images of (k) pristine lithium, (l) mechanically modified lithium, (m) mechanochemically modified lithium, and (n) lithium immersed for 1 day and (o) for 7 days. The Atomic force microscopy (AFM) measurements were performed using a NANOSENSORS™ PointProbe® Plus PPP-ZEILR AFM probe. (Contact Mode Low Force Constant - Reflex Coating).
