Figure 2 from Wei Han et al. “Toward Single-Atomic-Layer Lithography on Highly Oriented Pyrolytic Graphite Surfaces Using AFM-Based Electrochemical Etching” Schematic diagram of the AFM-based electrochemical etching apparatus with an RH-controlled environment. The experiments were performed under ambient conditions with a commercial atomic force microscope using NANOSENSORS PtIr5 coated PointProbePlus® PPP-EFM AFM probes. The AFM tip side coating enhances the conductivity of the AFM tip and allows electrical contacts, and the opposite side coating enhances the laser reflex.

Happy #NanotechnologyDay! The date, 10/9, is a nod to the nanometer scale, where objects span only billionths of a meter (10⁻⁹ meters). We celebrate it… Read More »Toward Single-Atomic-Layer Lithography on Highly Oriented Pyrolytic Graphite Surfaces Using AFM-Based Electrochemical Etching

Figure 4 from “Magnetic Skyrmions in a Thickness Tunable 2D Ferromagnet from a Defect Driven Dzyaloshinskii–Moriya Interaction” by Anirban Chakraborty et al. Thickness dependence of skyrmion size in lamella L2 as imaged by MFM. a) SEM image of the wedge-shaped lamella. The thickness of the lamella varies from ≈100 nm to ≈2 µm. b) MFM image of skyrmions in the lamella at 100 K and 0.032 T. c–f) Evolution of skyrmions as the field is increased from 0.1 to 0.2 T and finally reaches the field polarized state at ≈0.3 T. The blue and red contrast in the MFM images represent up- and down-magnetized domains. All MFM images are at the same scale: a scale bar is shown in (b). g) Skyrmion diameter as a function of lamella thickness including both MFM and LTEM data. NANOSENSORS SSS-MFMR AFM probes for magnetic force microscopy were used for all MFM measurements.

There is considerable interest in van der Waals (vdW) materials as potential hosts for chiral skyrmionic spin textures. Of particular interest is the ferromagnetic, metallic… Read More »Magnetic Skyrmions in a Thickness Tunable 2D Ferromagnet from a Defect Driven Dzyaloshinskii–Moriya Interaction

Figure 3 from “Monitoring SARS-CoV-2 Surrogate TGEV Individual Virions Structure Survival under Harsh Physicochemical Environments” by Miguel Cantero et al.: Treatment of TGEV with IGEPAL 0.2% (A). Topographical images before (left) and after (right) IGEPAL treatment (B). Profiles traced over the particles before (black) and after (blue) the treatment. The time interval between images was ~30 s (C). Height distribution of TGEV particles before (black) and after (blue) treatment (n = 103). Counts taken from the distribution curve were normalized for comparison. The peak shifts from the value of the intact particle height to the height of the cores. NANOSENSORS uniqprobe qp-BioAC AFM probes were used for the atomic force microscopy measurements.

Successful airborne transmission of coronaviruses through fluid microdroplets requires a virion structure that must withstand harsh natural conditions. * Because of the strict biosafety requirements… Read More »Monitoring SARS-CoV-2 Surrogate TGEV Individual Virions Structure Survival under Harsh Physicochemical Environments

Figure 5 from Morgan R. Jones et al. Stress- and Time-Dependent Formation of Self-Lubricating In Situ Carbon (SLIC) Films on Catalytically-Active Noble Alloys: Tribofilm formation as a function of number of cycles as determined from the nanoscale experiments. (a) Intermittent-contact mode topography images (3 µm × 3 µm area) of the contact region at a contact pressure of 1.2 GPa after 0 cycles, 500 cycles, 1000 cycles, 2000 cycles, 3000 cycles, and 4000 cycles. (b) Tribofilm volume as a function of cycles for contact pressures up to 3.1 GPa. For all P, tribofilm volume increased asymptotically to a steady-state value at large numbers of cycles. NANOSENSORS Diamond Coated PointProbe Plus AFM probes DT-CONTR were used for the nanoscale tribology with atomic force microscopy.

Although catalysis is a popular explanation for tribopolymer generation, the interplay of catalysis, mechanochemistry, and electrostatic interactions remain incompletely understood. There is consensus, however, that… Read More »Stress- and Time-Dependent Formation of Self-Lubricating In Situ Carbon (SLIC) Films on Catalytically-Active Noble Alloys
