Nanometrology as a basis of a sustainable development of nanotechnologies One of the key areas in nanometrology is insuring the uniformity of measurements in the nano- and sub-nanometer ranges. The most important parameters which characterize nanoparticles, nanostructures, and nanocoatings are , dimensional ones. In the article are described new types of silicon test objects that realize the traceability of dimensional measurements performed using scanning electron microscopy, transmission electron microscopy and atomic force microscopy to the SI meter.

Detection of the probe tip shape in atomic-force microscopy Determination of the parameters of the probe edge of a scanning atomic-force microscope (АFМ) with the use of nano-objects of known sizes presents serious methodical problems. They consist in complexity of finding of the samples of the preset sizes. In this article a number of aspects of these problems are discussed.

Dynamic Analysis of a Granulometric Composition A laser diffraction of a diffused light is frequently used method for analysis of a granulometric composition within the range from 1 mkm up to 1 mm. Modern systems of laser diffraction ensure have certain drawbacks. Even if a tool has been calibrated for the pharmaceutical purposes, the results strongly depend on its type and method of determination of the sizes of particles, and also on the version of software. The method also does not allow to obtain reliable results in measurement of small quantities of large particles, which is connected with a low resolution of particles within the range from several hundreds of mkm up to a mm. Dynamic analysis does not have such a difficulties.

Supercritical Fluids for Development of Nanomaterials Supercritical fluid (SCF) is a state, which appears, when a body is heated up to a critical point characterized by the temperature and pressure, individual for each chemical substance, at which density and also its chemical potential in the gas and liquid phases become similar. By its properties the formed phase is an intermediate between a liquid and a gas. Such a structure is characterized by a number of features, which make use of the environment very attractive for the purpose of mass transfer, including for work with nano-sized objects.

Microarc oxidation. properties of coatings Anodizing is the most widespread method for formation of nanostructured inorganic oxide coatings, which protect aluminum alloy products from the influence of the external factors. By the technological and economic indicators the microarc oxidation method (MAO), widely used by MANEL Co., can become its competitor. The method and properties of produced films in this article are described
