Olefin/paraffin separation is an important technological process. A promising alternative to conventional energy-consuming methods is employment of gas-liquid membrane contactors. In the present work, the membranes used were polysulfone (PSf) asymmetrical... see more

The object of research is an apparatus with jet injection gas filling. The studies are conducted on an experimental installation of a working medium of water-air. The distribution of gas phase bubbles is studied depending on the operating parameters of th... see more

Conventionally discussed dynamic mechanisms of elastic strain energy redistribution in near-contact surface regions include P and S elastic wave pulses radiating from the contact surface. At the same time, the elastic strain energy can be transferred by l... see more

Bathtube curves are often used by reability engineers to describe the life of a product's population. This graphical representation of the bathtube curve can be divided into 3 phases. The first phase of the curve is infant mortali... see more

Knowing the value of the surface energy of powder materials allows to predict the interaction of the solid phase with liquids, the formation of stable dispersions, durable and resistant to aggressive factors of composites. The application of the Owens-Wen... see more
