The quantification of surface structure is of major importance for several industry sectors. For the paper industry, the surface topography is essentially important for securing a good print quality of various paper grades. The surface affects various print quality parameters such as ink transfer, ink distribution, gloss and missing dots. It is thus important to have a detailed assessment of su...

Atomic force microscopy (AFM) techniques allowed us to visualize pentameric organization of immunoglobulins IgM and domain structure of immunoglobulins IgG. Together with obtained by AFM data on conditions of ribosome-inactivating proteins' type II (RIPsII) tetramerization these results contribute to many investigations concerning RIPsII biology as well as antigen-antibody and lectin-ligand int...

Pentacenequinone PnQ impurities have been introduced into a pentacene source material in a controlled manner to quantify the relative effects of the impurity content on the grain boundary structure and thin film nucleation. Atomic force microscopy has been employed to directly characterize by weight films grown by using 0.0%–7.5% PnQ in the source material. Analysis of the distribution of captu...

Atomic force microscopy (AFM) is a powerful characterization tool for polymer science, capable of revealing surface structures with superior spatial resolution. AFM is extremely useful for studying the local surface molecular composition and mechanical properties of a broad range of polymer materials, including block copolymers, bulk polymers, thin-film polymers, polymer composites, and polymer...

The effects of Surface morphological Properties of Nanostructured Bi1.6Pb0.4Sr2Ca2Cu2.70Zn0.30O10+δ based High Temperature Superconductors have been investigated. Bi1.6Pb0.4Sr2Ca2Cu2.70Zn0.30O10+δ superconducting samples are prepared by solid-state reaction route. Bi1.6Pb0.4Sr2Ca2Cu2.70Zn0.30O10+δ superconductors were prepared in bulk form. The phase identification /gross structural characteris...

By observing reconstituted chromatin by fluorescence microscopy (FM) and atomic force microscopy (AFM), we found that the density of nucleosomes exhibits a bimodal profile, i.e., there is a large transition between the dense and dispersed states in reconstituted chromatin. Based on an analysis of the spatial distribution of nucleosome cores, we deduced an effective thermodynamic potential as a ...
