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

Figure 4 from “Cytoskeletal disorganization underlies PABPN1-mediated myogenic disability” by Cyriel Sebastiaan Olie et al. Disrupted cytoskeletal spatial organization in shPAB human muscle cell cultures. A Representative images of control and shPAB human muscle cell cultures, stained with antibodies to tubulin and actin, and the actin filaments were visualized with actin-GFP. B Tubulin staining in control and shPAB myoblast cell cultures after DMSO, 100 nM nocodazole or 25 nM paclitaxel treatment for 2 h. Scale bar is 25 µm. C Measurements of cell-mechanics properties in control and shPAB cells using the Brillouin Light Scattering Microscopy (Ci) or the Atomic Force Microscopy (Cii). Measurements were carried out in myoblasts; every dot represents the median from 1000 measurements in a cell. Cell stiffness is measured by GHz, and the young modulus reports the cell surface tension. Averages and standard deviations are from N = 15 cells. Statistical significance was calculated with the student’s t-test. NANOSENSORS uniqprobe qp-BioAC ( CB3 ) AFM probes were used in the quantitative imaging of cell-mechanics properties where a force curve is applied at each point.

Muscle wasting is connected with changes in various cellular mechanisms that influence protein homeostasis, transcription, protein acetylation and different metabolic pathways. * Scientific studies have… Read More »Cytoskeletal disorganization underlies PABPN1-mediated myogenic disability

Figure 3. from “Nanoscale Charge Accumulation and Its Effect on Carrier Dynamics in Tri-cation Perovskite Structures” by David Toth et al: Initial dark and relaxed closed-loop KPFM analysis of CsFAMAPbBrI. (a) Topography channel plotting surface height. (b) KPFM image prior to light pulse plotting Vcpd. (c) KPFM image seconds after the light pulse plotting Vcpd. (d) 3D topography overlaid with the calculated ΔVcpd map. (e) Histograms of before and after Vcpd maps separated into grain and GB responses. The double arrows indicate the difference between the mean values of the distributions. NANOSENSORS™ Platinumum-Silicide PtSi-CONT AFM probes were used for the KPFM measurements.

Nanoscale investigations by scanning probe microscopy have provided major contributions to the rapid development of organic–inorganic halide perovskites (OIHP) as optoelectronic devices. Further improvement of… Read More »Nanoscale Charge Accumulation and Its Effect on Carrier Dynamics in Tri-cation Perovskite Structures
