Nucleation and detachment of polystyrene nanoparticles from plowing-induced surface wrinkling

Autor: Jana Hennig, Alexander Litschko, Juan J. Mazo, Enrico Gnecco

Publikováno v: Applied Surface Science Advances, Vol 6, Iss , Pp 100148- (2021)

We report the formation of spherical particles (up to 250 nm in diameter) from polystyrene surfaces repeatedly scratched by atomic force microscopy nanotips (nominal radius < 10 nm) along a series of parallel lines. The particles nucleate from the cr

Dynamical robustness of collective neuronal activity upon targeted damage in interdependent networks

Autor: Sergio Faci-Lázaro, Tatiana Lor, Guillermo Ródenas, Juan J. Mazo, Jordi Soriano, Jesús Gómez-Gardeñes

Publikováno v: The European Physical Journal Special Topics. 231:195-201

In the last decades, the availability of data about the structure of social, technological and biological systems has provided important insights on the mechanisms governing their correct functioning and robustness. These mechanisms are grounded on t

Locking effects in plowing-induced nanorippling of polystyrene surfaces

We have investigated the influence of the geometric shape bounding the scan pattern on the orientation of the nanoripples evolved from a polystyrene surface scraped by a silicon tip. Atomic force microscopy measurements at ambient conditions are comp

The emergence of surface patterns on the surfaces of compliant materials subject to plowing wear is a complex problem which can be quantitatively characterized, e.g., on polymer surfaces scraped by an atomic force microscope (AFM) tip. Here we explor

A physical picture for mechanical dissociation of biological complexes: from forces to free energies

Single-molecule force spectroscopy is a powerful technique based on the application of controlled forces to macromolecules. In order to relate the measured response of the molecule to its equilibrium and dynamic properties, a suitable physical pictur

Thermal versus Mechanical Unfolding in a Model Protein

Autor: Fernando Falo, Juan J. Mazo, Rafael Tapia-Rojo

Force spectroscopy techniques are often used to learn about the free energy landscape of single biomolecules, typically by recovering free energy quantities that, extrapolated to zero force, are compared to those measured in bulk experiments. However

We present a model of an ATP-fueled molecular machine which pushes a polymer through a pore channel. The machine acts between two levels (working-waiting), and the working one remains active for a fixed time giving a constant force. The activation ra

In this work we study the assisted translocation of a polymer across a membrane nanopore, inside which a molecular motor exerts a force fuelled by the hydrolysis of ATP molecules. In our model the motor switches to its active state for a fixed amount

We demonstrate how an exponentially saturating increase of the contact area between a nanoasperity and a crystal surface, occurring on time scales governed by the Arrhenius equation, is consistent with measurements of the static friction and lateral
