Science & Technology

Supplemental Figure. 6. From Macrea et. al “A fibrin biofilm covers blood clots and protects from microbial invasion” Mechanisms and roles of fibrin film. A, Sneddon model used to calculate Young’s Modulus, where F is the force from the force curve, E is Young’s modulus, ν is Poisson’s ratio (0.5), α is the half angle for the indenter (15 degrees for our tips), and δ is the indentation. Note that this equation is only accurate with a half angle of 15 degrees for the first 200nm of indentation. B, Strength of the fibrin film in clots produced with plasma and thrombin with or without T101 (FXIII inhibitor ) investigated using atomic force microscopy (AFM). Fibrin fibres were visible under the film surface and these areas presented with stiffer Young’s modulus than fibrin film suspended between fibres. Grey lines in the zoomed-in images represent Young’s modulus scan area represented in the line force graphs. Scale bar - 2μm. C, Young’s Modulus was calculated for the suspended film and the film supported by fibers with and without T101 by fitting a Sneddon model to all AFM force curves found over the entire area that was imaged. 20 measurements were taken for each condition. **** P

Figure 6 from Mir & Ochiai "Conductive Polymer-Ag Honeycomb Thin Film: The Factors Affecting the Complexity of the Microstructure* a) Topography SPM image, and b)I-V curves of the polymer-Ag honeycomb film on HOPG (preparation conditions for polymer-Ag honeycomb film: poly(NVK-co-MAH)-g-PMMA from PMMA (Mn=2100), 0.3 mg mL−1 and 50μL; measurement conditions: topography SPM image was taken by contact mode using microfabricated PtSi- coated cantilever (f0: 15 kHz, C: 0.2 N m−1), and the I-V curves were taken at specific points. NANOSENSORS PtSi-CONT AFM probes were used for the Current-sensing scanning probe microscopy (CSSPM) images

Figure 1 from "Resonant torsion magnetometry in anisotropic quantum materials": Schematic overview of resonant torsion magnetometry. a First and second derivatives of the free energy with respect to the magnetic field B and the field orientation θ. b The quartz tuning fork of the Akiyama A-probe (http://www.akiyamaprobe.com) is electrically excited at the lowest-resonance mode of the silicon cantilever, producing a large out-of-plane motion at the tip of the cantilever. c Schematic representing the principle of measuring the magnetotropic coefficient k. In a magnetic field, the magnetic torque brings the lever to a new equilibrium position. The magnetic energy of the samples changes the effective stiffness of the lever, leading to a shift in the resonant frequency. d The silicon cantilever glued to each leg of the quartz tuning fork with a single crystal of RuCl3 mounted at the tip with Bayer silicone grease
