Structuring of water solutions of polyvinyl alcohol by physical and chemical methods [PDF]

open access: yes, 2018
Multifunctional materials based on an aqueous solution of polyvinyl alcohol were prepared and investigated. The materials were obtained by physical and chemical cross-linking, resulting in cryogels and hydrogels, respectively.

Current evaluation of the tripropellant concept [PDF]

open access: yes
An analytical study was conducted to determine the specific-impulse advantages of adding metals to conventional liquid-bipropellant systems. These tripropellant systems theoretically offer higher specific impulse and increased propellant density compared
