Engineering novel material structures has continually been pursued to further advance modern technologies. These advancements often rely on novel processing technologies. Although many processing parameters have been thoroughly examined in the field of composition coatings, the formation processes are an exception. In this work, we examine the unique microstructures of composite electrolytic coatings, obtaining from electrolytes-suspension which contains nano-size particles of SiO2 and carbon. Metallographic resea...

The article deals with of a hydrogen pressure vessel suitable for high pressure of approximately 75 MPa. One of the goals is to design a vessel from materials whose strength will meet mechanical requirements a calculated in both analytical and numerical ways. Another objective is the simulation of the design the pressure vessel with regard to safety and weight requirements.

In this work, synthesis and swelling of a superabsorbent hydrogel based on copolymer of acrylic acid and acrylamide filled with pectin were investigated. The structure, thermal stability, sorption capacity and morphologies of the developed composites were characterized by Fourier transform infrared spectroscopy (FTIR), thermogravimetric and differential scanning calorimetry analysis (TG-DSC), voltammetry and scanning electron microscopy (SEM). In addition, the swelling properties, and the stimuli-responsive behavi...
