Sorbents are widely used in purification of v.rious liquids and gases, offering a univ.rsal means for wastewater and air cleaning. The most promising sorbents are those obtained from agrowaste products such as rice or buckwheat husk. Processing of husk in cold plasma modifies the composition, structure and surface properties of the raw material and raises its porosity, thus substantially improv.ng the sorption properties of the final *** as a raw material for producing sorbents has the following adv.ntageous properties: (1) appropriate chemical composition; (2) low cost; (3) high dispersity, due to which there is no need in any special treatment of the material prior to its exposing to plasma; (4) scaly structure and dev.loped porous surface ensuring a high surface-to-v.lume ratio. The best properties are displayed by the sorbents obtained in cold plasma under reduced pressures of 53.2 Pa. The raw material trav.rses the region occupied by the plasma and, as it does so, it gets heated up to a temperature of 250 - 350 ℃. The whole process inv.lv.s two stages: combustion of the raw material and modification of its properties under the action of the plasma. The combustion proceeds due to the oxygen contained in the starting material. During the combustion, the hydrogen contained in the starting material and some part of the carbon also burn out. The resultant scaly sorbent is accumulated in a cooler. The scales are black; they range in sizes from 1mm to 5 mm. The sorbents obtained are remarkable for their useful properties and outperform most of the traditional sorbents used in modern industry. The starting materials are inexpensiv., and their resources are almost unlimited. The sorbents hav. rather a low production cost (1.8-2.5 $/kg). The sorbents can be used for cleaning hydrosphere from water pollutants on a large scale. The degree of cleaning water surface from oil products with sorbents was a subject of inv.stigation. The highest degree of purification th

Fuzzy models with hybrid algorithms of adaptation allow to predict complex temporary processes successfully. This article shows how we can use fuzzy difference TSK model for traffic flow predictions. Described hybrid algorithm, it uses fuzzy logic, neuro - fuzzy network and recurrent algorithm. Hybrid algorithm consists of two types identifications: parametric and structural. We apply it for traffic data from California and compare with another prediction methods.

关键词： system model fuzzy model the rule of inference parameter estimation hybrid algorithm traffic flow.

Application of cold plasma technology in fiber-reinforced composite materials

广东有色金属学报 2005年第2期15卷 578-580页

作者： kudinov v.v. Abdullin I .Sh. Korneev. N.v. Baikov.Institute of Metallurgy and Materials Science of Russia Academy of Sciences Moscow119991 Russia Kazan State Technological Univ.rsity Kazan 420015 Russia Semenov.Institute of Chemical Physics of Russian Academy of Sciences Moscow119991 Russia

A study is presented concerning a cold plasma technique for improv.ng the bondability of high-strength high-modulus multi-filament polyethylene fibers to polymer matrices and the fibers impregnation with the objectiv. to fabricate composite materials (CMs). Strong bonding between the matrixes and reinforcing fibers during the production of composites appears in the case if interaction is chemical. The v.lue of the activ.tion energy of the chemical interaction for v.ry high performance polyethylene fiber was estimated. It was 1.14 ev. This allows using the cold plasma technique for producing CMs. In order to understand the effect of cold plasma treatment treated and untreated fibers were used to fabricate CMs. The strong bond between the matrix and plasma-activ.ted fibers affects both the properties and failure mode of composite. The properties and failure modes were compared to those of CMs reinforced with untreated fibers. After plasma treatment the properties of CMs are increased. CMs are broken as a unit whole under tension. The ideas of the activ.ting the fibers by cold plasma treatment abov. the activ.tion energy of the chemical interaction may be extended ov.r other types of the fibers and matrices to produce new types of fiber-reinforced composite materials with high physicomechanical indices.
