“…In addition, as evidenced by our study, humic substances are capable of self-assembling and selforganizing thanks to the ability to form structural elements of fractal systems [12,13]. Two-dimensional confocal microscopy showed that the fractal dimension of the pyrolysis product in our experiment is 1.5-1.8.…”

“…Moss was additionally carbonized in concentrated solution of the liquid peat phase (the analogue of sodium humate) [11] at the rate of 1 litre per 1 kg of air-dry moss. This procedure also assisted in rendering fractal characteristics to moss samples, which are unique to humic acids [12]. Materials obtained from this kind of raw materials gain the capacity to self-organize and self-assemble [13].…”

The article discusses the results of experimental synthesis of fullerenoids from naturally occurring biogenic materials. Mechanical activation of amorphous carbon derived from Sphagnum moss (Sphagnum fuscum) turns it into carbon nanotubes. It is shown that conditions approximating those in the experiment can be generated in settings of active continental margins and intracontinental rifting when lava flows into the basins where sapropels deposited.

Technique for production of powder sorbents from renewable plant raw materials, wastes from cereal plants and sphagnum moss species, were considered. Their sorption properties with respect to dissolved and emulsifi ed oil products were studied.It has been shown previously [1-7] that amorphous, mixed, or crystalline carbon modifi cations produced in pyrolysis of renewable plant raw materials, wastes from cultivated plants, are characterized by a high yield of pure carbon (~99.4-99.8%) and show good electrochemical, physicochemical, mechanical, and technological characteristics. This enables use of carbon modifi cations as anode materials for lithiumion (polymeric) batteries and as a starting component for mechanochemical synthesis in manufacture of highmelting compounds [6][7][8].In addition, renewable plant raw materials can be used (without a pyrolytic treatment) as effective oil sorbents in the form of a dispersed powder mass [9][10][11].The goal of our study was to produce and examine powder oil sorbents 1 from renewable plant raw materials, wastes from cultivated plants (cereals: wheat and oat husks) and sphagnum moss species and analyze their sorption characteristics with respect to dissolved and emulsifi ed oil products.As starting raw materials served wastes from cereals (wheat and oat husks) and sphagnum moss species collected in raised moors of Lower Amour River region [7,8].To reach their air-dry state, the raw materials were preliminarily dried in a Binder thermal box at a temperature of 70°C and cleaned by sieving to remove foreign admixtures. Then the air-dry raw materials were in turns charged into the working reservoir of a Desi disintegrator and processed during 7 min for wheat and oat husks and 5 min for sphagnum moss species until a homogeneous powder mass with particle size of 45-50 μm was obtained. The dispersity was monitored with a Fritsch laser particle size analyzer.The bulk density was determined by weighing: a 20-cm 3 graduated and calibrated polypropylene syringe was charged with the powders obtained, the surface was leveled with a plunger, the volume of the powders was measured, and then they were weighed. After that a force of 10 kg was applied via a dynamometer to the plunger handle, with a compacting pressure of 3.2 kg cm -2 created, and thus the volume of the powders was determined and their rammed density was calculated.The pore capacity was determined against water: a 10-cm 3 portion of a powder was weighed within a graduated syringe, water was added, the mixture was agitated until a fl owing suspension was obtained, the excess amount of water was squeezed out with the ---------------1 Three kinds of powder oil sorbents were formed at "Synthesis of inorganic materials" and "Materials science and technology of nanomaterials" laboratories at Far-Eastern Federal University.
