Magnetic nanomaterials produced by IR pyrolysis
Nanostructured magnetic materials have been produced for the first time by IR pyrolysis of cobalt polyacrylonitrile/acetylacetonate compositions. These materials are metal-carbon nanocomposites, in which Co particles (d=9-13 nm) encapsulated in carbon nanofunnels (d=50-100 nm) are uniformly distributed in the carbon matrix. At the 1200°C IR pyrolysis the carbon matrix has the crystalline graphite structure. Produced nanocomposites are ferromagnetic. If Co content is only 17 %wt, saturation intensity (170 μ/gCo) corresponds with bulk sample magnetization bulk sample.

Original technology of C2-C4 olefin production from natural gas
A new approach has been developed to solve the main problem of XXI century – natural gas transformation to lower olefins - basic feed of petroleum chemistry. An original technology of C2-C4 olefins production from natural gas via DME (including its isomerization and dehydratation stages) has been proposed. Catalytic systems have been found, optimal parameters of every process stage have been determined providing C2-C4 olefins yield of 80-85% per DME, which is 10% higher than the best world analogues. Proposed technology provides efficient utilization of carbon feed and dramatically decreases energy demands per target product unit.

Novel process of biodestructed polymeric derived polypeptide targeted transport medical products
A novel production method of biodestructed polymeric derived polypeptide (protein) targeted transport medical products has been developed. It has been proposed for the first time to use polypeptide medicine itself with immobilized low-molecular synthetic polymer, having low critical mixing temperature, as a biodestructured component. During the research of the produced products containing 1-16 synthetic polymer chains per 1 protein macromolecule it has been shown that the more polymer carrier chains are grafted per protein molecule, the higher its permanence to enzymic hydrolysis is and the lower molecular weight hydrolysis products have, which eases their elimination from organism.

Gasoline production from natural and associated gases via dimethyl ether
Institute developed an original technology of high-selective two-stage gasoline production from syngas (CO+H2) via dimethyl ether (DME) without DME intermediate separation, which allows to carry out gasoline synthesis in flow-circulating operation mode of two-module reaction unit. The catalyst production technology of direct (one-stage) DME synthesis from syngas has been tested at the NIAP pilot plant (Novomoskovsk city), the zeolite (nanostructuted) catalysts production technology of DME transformation to gasoline has been tested at Angarsk plant of catalysts and organic synthesis. The technology of gasoline production from DME has been tested at the pilot unit at Primorsk research and development centre “Energy”. At the quantitative DME conversion the yield of gasoline fraction with 90 octane number is 70%. Universality to feedstock is a significant advantage of this technology: it is equally effective for all the syngas sources (biogas, associated petroleum or natural gas). The process catalysts have high stability and no loss in activity during 600 hours. The work is patented with Russian Federation patents and is ready for implementation.
Vapour-diethylbenzene production by ethylbenzene disproportioning over heterogeneous nanostructured catalysts
An original catalyst of ethylbenzene disproportioning to п-diethylbenzene, valuable feed for petroleum chemistry, has been developed on the basis of industrial pentasil-type zeolite. The catalyst is regenerated easily and has high activity and 98,6-99% selectivity to п-diethylbenzene at production of 620 g/g of catalyst per cycle. Catalyst lifetime is more than 350 hours. Catalyst production technology and process procedure on ethylbenzene disproportioning unit design have been developed. The work is patented with Russian Federation patents and is ready for implementation.

Original method of chlorine and bromine determination
An original method of chlorine and bromine determination at its simultaneous presence in organic compounds and petroleum products. It is based on the double-burning method with the following acidimetric halogens sum determination and iodimetric bromine determination. The method is used at Nizhnekamsk petrochemical plant for halogen-containing rubbers analysis.

Polymer medical-purpose adhesives
Institute continues to collaborate with Corium Int. (USA). Within the long-term agreement the joint patent polymer medical-purpose adhesives are produced: tooth enamel recovering preparations, feet supinators, antimicrobial coating on bedsores and trophic ulcers (6 types of products in total). Products are realized on pharmaceutical markets in USA.

Method of biological fluids steroid profile determination
There are more and more medical institutions, which use the unique chemical chromatographic method of biological fluids steroid profile determination developed by the Institute. At the present time more than 40 Moscow and Moscow region clinics use this method which allows to detect a number of devastating endocrine, gynaecological and oncological diseases. The method is also used in veterinary medicine, particularly for selected selection in livestock breeding selection.

Membrane palladium sponges
TIPS RAS jointly with IMET RAS and Sinplaz Ltd. has developed membrane palladium sponges (Pd-Y-Ru). It has been shown that specific permeability of the most efficient sponges 1.5-7 times exceeds specific permeability of the developed before and widely used sponges PdAg23, PdCu42, В1 and PdInRu. The Institute has made capacity calculations of the flat membrane elements with the palladium-sponge membranes, filter units and modules, and also the pure hydrogen (>99.9999%) recovery ratio from industrial hydrogen-containing gas mixtures in the concrete developed construction in wide range of defined operating parameters (Т=300-800°С, partial hydrogen pressure in mixture before the membrane - 1-5 MPa, and recovered pure hydrogen – 0.1-3 MPa). Jointly with Sinplaz Ltd. and S.P. Korovel research center “Energy” the Institute has developed, manufactured and tested the pure hydrogen recovery modules with the capacity of 5-120 m3/h. The product is ready for implementation.
