The mechanical stability of conventional single-channel capillary fibres can be improved in a multi-channel geometry, which has previously found application in ultrafiltration. In this work, multi-channel polyethersulfone (PES) capillary membranes comprising seven feed channels were successfully fabricated in an enhanced steam–dry–wet spinning process and coated on the inner surface with a thin...

Hydroxyapatite (HA) is considered to be a bioactive material that favorably influences the adhesion, growth, and osteogenic differentiation of osteoblasts. To optimize the cell response on the hydroxyapatite composite, it is desirable to assess the optimum concentration and also the optimum particle size. The aim of our study was to prepare composite materials made of polydimethylsiloxane, poly...

An ideal bone plate for internal fixation of bone fractures should have good biomechanical properties and biocompatibility. In this study, we prepared a new nondegradable bone plate composed of a ternary nano-hydroxyapatite/polyamide 66/glass fiber (n-HA/PA66/GF) composite. A breakage area on the n-HA/PA66/GF plate surface was characterized by scanning electron microscopy. Its mechanical proper...

The use of biomass combustion ash as a reinforcing filler has taken the attention in recent years to reduce overall production cost and increase mechanical properties plastics. This study evaluates effect boilers (BBA) on polyamide 6 composites (PA6). chemical composition thermal stability BBA were analyzed by X-ray fluorescence (XRF), Thermogravimetric analysis (TGA), Differential (DTA) thermo...

A fabric, tapes, that are glued to the outer tensile surface, which considered as external composite reinforcement with steel reinforcement, currently used strengthen reinforced concrete beams. The results of experimental studies presented in this article have shown possibilities effective application technical polyamide (nylon) fabric produced by «Khimvolokno Plant» JSC «Grodno Azot», and glas...

Nano-hydroxyapatite/polyamide 66 (nHA/PA66) composite with good bioactivity and osteoconductivity was employed to develop a novel porous membrane with asymmetric structure for guided bone regeneration (GBR). In order to test material cytotoxicity and to investigate surface-dependent responses of bone-forming cells, the morphology, proliferation, and cell cycle of bone marrow stromal cells (BMSC...
