In wide temperature range IR spectra of cyclohexanol in different phase state (plastic phase, crystal phases II, III) have been measured in range 600–3600 см–1. Using density functional method B3LYP/6-31G structural – dynamic models of conformers of cyclohexanol molecule, which differs from each other by orientation of hydroxyl group relatively carbonic ring and cyclohexan, have been constructed. The energy, structure, dipole moments, polarizabilities and the frequencies of the normal modes in harmonic approximation and IR intensities have been calculated.

The biofilms of Staphylococcus aureus and Escherichia coli have been investigated by atomic force microscopy (AFM). The usage of complex approach of semi-contact AFM mode has shown that the S. aureus and E. coli biofilms represent an organized community of microorganisms. Semicontact error mode and phase imaging mode investigation of extracellular matrix of S. aureus and E. coli biofilms, confirms dimensions of bacteria and biofilms.

This review presents data about current application of scanning probe microscopy in microbiology research. Methods of scanning probe microscopy belong used to study the ultrastructural and morphological features of microorganisms, their mechanical properties et al. The review also present data about the development methods of scanning probe microscopy to study microorganisms and their communities.

This article presents dynamics of dual phase, which is connected with dual character of dions – hypothetical particles possessing both electrical and magnetic charges. For description of dual phase the set of equations is received from condition that Maxwell equations conserve their electrical character under dual transformations, what corresponds to effective electrical charge of dion. Some special solutions of these equations for example in vacuum, and in field of electrical dipole are found.
