AbstractA procedure was developed for preparing composites of nanocrystalline cellulose (NCC) with poly(ethylene terephthalate) (PET). Poly(ethylene terephthalate) and PET/NCC composites were prepared by a continuous procedure in two steps: esterification of terephthalic acid with ethylene glycol and polycondensation. The morphological, thermal, so...

AbstractThe effect of the precipitant nature of the tin(II) hydroxoform on the composition, structure, and surface morphology of samples based on tin(II) oxide prepared by precipitation under the same conditions with various precipitants: NaOH, a mixture of NaOH with hexamethylenetetramine, and NH3 solution, was studied. It was found by X-ray phase...

AbstractThe efficiency of using seven cubane derivatives as dispersing components of solid generator propellants was studied. With cubane, bicubyl, or 1,4-dicubylbenzene used as a propellant dispersant, the aerial vehicle range can be increased to the level considerably exceeding the range reached with other compounds considered for this purpose pr...

AbstractThe influence exerted by the conditions of the preliminary synthesis of Si3N4 by nitridation at 1350 and 1400°С and additional high-temperature sintering at 1800 and 1900°С on the properties of reaction-bonded silicon nitride was studied. Secondary silicon nitride (β-Si3N4) formed in the course of nitridation consists of needle-like grains,...

AbstractThe effect that diatomite in various ion-modified forms, introduced as active filler, exerts on the adhesion durability of bitumen–inorganic protective systems at their cathodic polarization was studied. The cathodic disbondment and, as a consequence, the adhesion durability of bitumen–polymer protective coatings depend on the ionic composi...

AbstractThe liquid fraction of tire pyrolysis products was comprehensively analyzed by gas chromatography–mass spectrometry and two-dimensional gas chromatography. The direct (nonpolar–polar) и and inverse (polar–nonpolar) column combinations were used. The inverse combination allows efficient separation of alkanes and alkenes. Aliphatic hydrocarbo...

AbstractThe optimization of the molecular structure of substituted 3,5-toluylene diamines was carried out by the ab initio method, which made it possible to calculate the volume of stretching vibrations and the steric factor of the ethyl and methylthiol substituents on the basis of the data obtained on the bond lengths and bond angles. A linear dep...

AbstractThe use of commercial magnetite-type iron ore and of ferriferous quartzite type ore as catalysts for low-temperature Fischer–Tropsch synthesis is described. According to the results of chemical analysis, the ores mainly contained iron magnetite, carbon, and also baddeleyite (ZrO2 + HfO2) and hatchettolite (Ta2O5 + Nb2O5 + U3O8). The ore sam...
