  • Statistics of AFM current-voltage curves

    Open Research Data
    open access - series: Scanning Probe Microscopies data

    Mapping surface electrical conductivity offers enormous cognitive possibilities regarding the structure and properties of modern materials. The technique invented for this purpose (Conductive AFM) by Murrel's team and colleagues allows independent monitoring of the local conductivity of materials in correlation with the topographic profile. The mentioned...

  • Imaging of biological samples: the ant Lasius Niger

    Open Research Data
    open access - series: Scanning Probe Microscopies data

    The world of arthropods continues to amaze researchers today. An example may be a relatively new report by a group of scientists on structures found in ant shells [1] Although calcareous anatomical structures have evolved in various groups of animals, little has been known so far about the occurrence of this type of form in insects. The authors of the...

  • Fingerprint structure studies with semi-contact AFM

    Open Research Data
    open access - series: Scanning Probe Microscopies data

    The work [1] presents many, sometimes even surprising examples of the use of atomic force microscopy in modern forensics. Some of them are projectile tests using the characteristic scratch patterns created by the firing pin on the primer. There are more and more suggestions in the literature for the use of atomic force microscopy in dactyloscopy [2]....

  • Destruction of AFM probes during normal operation

    Open Research Data
    open access - series: Scanning Probe Microscopies data

    The quality of the images obtained with the use of an atomic force microscope is determined by the state of the blade interacting with the tested material. Image artifacts can be generated by various reasons, such as oxidation, contamination or an error in blade fabrication, but also appear as a result of the repeated scanning process and inevitable...

  • Visualization of the surface of the Nafion membrane

    Open Research Data
    open access - series: Scanning Probe Microscopies data

    Fuel cells use the chemical energy of hydrogen or other fuels to produce electricity. If the fuel is hydrogen, the only products are electricity, water and heat. Fuel cells are unique in the variety of their potential applications, they can use a wide variety of fuels. They are also highly scalable devices that can power both cars and mobile phones....
