Nonwoven Polymeric Fabrics Modified by Poly(Dimethylphosphazene)
JUNIPER PUBLISHERS- ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract This review presents poly(dimethylphosphazene) (PDMP), as the simplest representative of poly[(organo)phosphazenes], which was used as the additive into commercial polymer mixtures. This mixture was electrostatically spun. The formation and behaviours, such as wettability, of PDMP modified layers, were investigated. Phosphazene; Poly(dimethylphosphazene); Electrospinning; Nanofibers Introduction and Theory The effort to make new materials from already well-known compounds is the goal of many current scientists. The synthetic possibilities in polyphosphazenes chemistry has enabled the development of a wide range of matrixes with a variety of physical, chemical, and biological properties. Poly[(organo)phosphazenes] introduce a unique class of extremely versatile compounds with huge potential for various applications. Due to their high ability to be functionalized by a wide range of side groups, [1]...
Research of Hydrogen Absorption-Desorption by Ti-Al-Nb Alloy-Juniper Publishers
Authored by Kurbanbekov ShR Abstract The paper presents kinetics of hydrogen sorption of Ti-23.5at%Al-21.5at%Nb alloys in isothermal conditions underthe temperature of 450, 500 and 550 °С. It was determined that maximum quantity of absorbed hydrogen is observed at material of sorbed alloy under the temperature of 550 °С. That presents approximately 0.289mass%. It had been found that hydrogen is released under the temperatures within 700 …790 °С. In addition, it was revealed that maximum release of hydrogen composes 85% of samples saturated...
