Opis:
Scanning force microscope has been applied to investigate wear tracks produced during friction coefficient measurements of hard steel ball against ⟨111⟩ silicon crystals implanted with Ar ions. Such treatment causes the stable and significant decrease in friction, despite the total removal of implanted species from the wear track during friction. Scanning force microscope measurements of wear tracks topography supported the former hypothesis assuming the formation of post-implantation dense microcracks structure and subsequent propagation of this structure into the bulk. Such process assures small size of wear particles and a low friction coefficient value. Additionally the microfriction force measurement method was applied to determine the friction coefficient of Si$\text{}_{3}$N$\text{}_{4}$ cantilever and a wear track in Si crystal.

Opis:
Scanning force microscopy was used in the contact mode to determine the adhesion force between a mica surface and a silicon nitride tip. The measurements were performed in an aqueous solution of sodium and calcium chlorides. The adhesion force according to the Derjaguin-Landau-Verwey- Overbeek theory depends on the competition between two kinds of forces: van der Waals and electrostatic "double layer". Two different curves of adhesion force versus salt concentration were obtained from the experiment with monovalent and divalent ions. The tip-surface adhesion force was determined from a statistical analysis of data obtained from the force vs. distance retracting curves.

Opis:
The aim of this investigation was to determine the adhesion force as a function of calcium dichloride concentration in water. The studies were performed with two surfaces carrying opposite charge in water solution: mica - as a negatively charged surface and glass covered with poly-L-lysine - as a positively charged surface, the latter due to the presence of amino groups. The surfaces were immersed in a CaCl$\text{}_{2}$ solution in the range of concentration varied from 0 to 100 mM. The scanning force microscopy was applied to determine the adhesion force by measurements of the pull-off force. Additionally, the values of the single bond force were estimated basing on the Poisson distribution of the number of binding sites.

Opis:
Testing Si3N4 membrane windows is a preliminary research for the single-ion-single-cell irradiating programme prepared at the Cracow nuclear microprobe facility. The present investigation is concerned with finding a method to register every single particle of the microprobe beam when passing through a membrane to the atmosphere. The 200 nm thick membranes covered with different layers were investigated. The alpha particles, after passing the membrane window, were registered by a particle detector. Secondary electrons ejected from the membrane by alpha particles were registered by a channeltron. The channeltron signals were collected in coincidence with the silicon detector signals. The detection efficiency is the ratio of the fast coincident channeltron signal number to the total number of the silicon detector signals. The results of investigation of the membranes with different coverages are reported in the present work.

Opis:
An atomic force microscope is a useful tool to study the interaction forces at molecular level. In particular the atomic force microscope can measure an unbinding force needed to separate the two single molecule complexes. Recent studies have shown that such unbinding force depends linearly on the logarithm of the applied loading rate, defined as a product of scanning velocity and the spring constant characterizing the investigated system (cantilever vs. surface). This dependence can be used to study the energy landscape shape of a molecular complex by the estimation of energy barrier locations and the related dissociation rates. In the present work the complex consisting of ethylene(di)aminetetraacetic acid and the bovine serum albumin was measured. The dependence between the unbinding force and the logarithm of the loading rate was linear. Using the Bell model describing the dissociation of the above molecules caused by the action of the external bond breaking force, two parameters were estimated: the dissociation rate and the position of the energy barrier needed to overcome during a transition from a bound to unbound state. The obtained results are similar to those obtained for a typical ligand-receptor interaction.

Opis:
In this paper a numerical approach to analyze the dynamic stability of a ribbed plate subjected to harmonic loading is presented. The harmonic balance method and the modified Newmark method of direct integration to solve the equations of motion are used, Unstable regions which include resonant frequencies of the external load are discussed. Then the Stability loss occurs by flutter, i.e. exponentially growing oscillations. The modified Newmark direct integration method to analyze the equations of motion is used. Some results which describe the time history of resonance vibrations (unstable) and those nonresonances (stable) are presented. The  effects of constraint parameters such a modulation depth beta and constraint frequency fi are investigated. Also the initial load and internal damping are taken into account. Physical rigidity of plate may be changed by adding initial tension load, and currently resonance vibration will transform to non-resonance. Stability of the system by means of initial load is the more effective, the larger is the system rigidity in the direction of putting the load, as then may be introduced larger value of initial load. Stability of the system by means of initial load is the more effective, the larger is the system rigidity.
