Organizations are subject to a variety of constantly changing internal and external influences, such as organizational strategy and environmental conditions. Of these, of particular importance are the development of the global marketplace and increasing global competition, and the emergence of a knowledge‐based economy that is characterized by a high level of development of communications and information technologies. In response to these factors, new forms of organization structure have emerged: the horizontal organization, the network organization and the virtual corporation. Asks whether such structures are adequate to meet the constant change of the world into which we are moving, and whether they can meet the needs of organizations in varying situations in different economies in disparate countries and with different cultures.

This paper aims to characterize community archives in the common array of the manuscript collection of the National Library of Russia (NLR). The purpose of the paper is to identify the features of organization of the archival system of Russia and the place of community archives in it. The authors intend to characterize the features of origin, history of existence and preservation of archives of public organizations in Russia on the example of the archives of Russian societies of the nineteenth and twentieth centuries; to spread knowledge about historical communities of Russia and their archival heritage and to discuss the value of community archives and their information potential.

The research is based on the traditional methodology of the academic archival studies. At the same time interdisciplinary approach plays a great role in the field of study of community archives. The findings of the study were obtained as a result of the application of methods of historical research and special historical disciplines: archival heuristics, archive studies, source studies and archeography. The data were complemented by documentary analysis, including materials of nine archives, documents concerning acquisition and storage of these archives.

As a result of the study of different community archives in the Manuscript Department of the NLR the authors came to the conclusion about poor preservation and diffusion of these archives. It suggests the necessity of developing methods of virtual archive reconstruction.

This is the first study to date on the community archives in Russia. The first attempt to attribute and classify community archives of the NLR.

This paper aims to synthesize silver nanoparticles using atmospheric discharge plasma in contact with liquid at different pressure in reactor and to assess their catalytical properties for reducing 4-nanoparticles (NP).

The Ag colloidal NPs was rapidly synthesized as a result of non-equilibrium low-temperature plasma formation between an electrode and the surface of AgNO₃ solution for 5 min at different pressure in reactor. Synthesized Ag NPs were characterized with common analytical techniques. Ultraviolet–visible (UV) spectroscopy, dynamic light scattering, scanning microcopy analysis were used to study the formation and characteristics of silver nanoparticles.

The formation of silver colloidal solutions under plasma discharge at different pressure in reactor is characterized by the presence of surface resonance peak in the spectra. Scanning electron microscope (SEM) images confirmed the formation of spherical particles having a size distribution in the range of 15-26 nm. The AgNPs solution showed excellent rapid catalytic activity for the complete degradation of toxic 4-nitrophenol (4-NPh) into non-toxic 4-aminophenol (4-APh) within 18 min.

Further studies are necessary for confirmation of the practical application, especially of deposition Ag NPs on TiO₂.

The method provides a simple and practical solution to improving the synthesis of colloidal solutions of Ag NPs for degradation of organic pollutants (4-NPh) in water and wasters water.

Atmospheric discharge plasma in contact with liquid at different pressure can be used as an effective technique for synthesis of nanomaterials with catalytic properties.
