The article deals with the experimental study of the mass transfer of acetic acid from the dispersed phase (butyl acetate) to the continuous phase (water). The experiments were carried out on a laboratory column with single floating drops. ... see more

The object of this study is a technology of the new surface-active substances (SAS) based on sulfomethylated phenol. The study's aim was to improve the technology by a catalytic method, implying the development of industrial schemes for the synthesis proc... see more

Fibre-reinforced composite materials are considered to comprise three components, i.e., fibre, matrix, and the interphase. The interphase is the part of the matrix placed in the vicinity of fibre surface all along its length and has distinct properties fr... see more

 

Design diagram of experimental setup for studying the mass exchange processes occurring during formation of gas hydrates was presented. A procedure of performing studies and the use of equipment for conducting experiments in a diffusion mode with the use ... see more

For the first time are studied interpolyelectrolyte reactions of copolymers of an alternating structure butyl vinyl ether – malein anhydride with the polymer of cationic type – polydimethylaminoethylmethacrylate in a water solution and on interphase borde... see more

In composites, a strong interphase between the components is essential for mechanical properties. By using a suitable sizing (i.e., surface modification) of the fiber, the interphase may be varied, e.g., by suppressing or promoting heterogeneous nucleatio... see more

Online commingled yarns were spun with three different polymeric matrices, namely polypropylene (PP), polyamide (PA) and polylactic acid (PLA) and glass fibers. Tailored sizings were applied for the three matrices and the resulting mechanical performance ... see more

In this paper, a geometric body-centered model to simulate the periodic structure of unidirectional fibrous composites is presented. To this end, three prescribed configurations are introduced to predict in a deterministic manner the arrangement of intern... see more
