Stress- and Time-Dependent Formation of Self-Lubricating In Situ Carbon (SLIC) Films on Catalytically-Active Noble Alloys

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

Signal Origin of Electrochemical Strain Microscopy and Link to Local Chemical Distribution in Solid State Electrolytes

Figure 1 from Nino Schön et al. «Signal Origin of Electrochemical Strain Microscopy and Link to Local Chemical Distribution in Solid State Electrolytes”: a) Topography, b) deflection error, and c) corresponding cantilever deflection change (Dac) map of a 30 µm × 30 µm area of LATP. d) Noncontact EFM amplitude map in the same area. NANOSENSORS conductive platinum-iridium coated PointProbe Plus PPP-EFM AFM probes were used.

Solid state electrolytes (SSEs) are interesting materials that could potentially replace the currently used organic electrolytes in lithium‐ion batteries (LIBs). * Electrochemical strain microscopy (ESM),… Read More »Signal Origin of Electrochemical Strain Microscopy and Link to Local Chemical Distribution in Solid State Electrolytes
