Properties of Rubberized Engineered Cementitious Composites Containing Nano-Silica [PDF]

open access: yesMaterials, 2021
To avoid explosive spalling during elevated temperature, crumb rubber (CR) is being added to the manufacturing of engineered cementitious composites (ECC). However, the addition of CR particles adversely affects the mechanical properties of ECC. Therefore, to overcome this issue, nano-silica (NS) is added into rubberized ECC mixture as cementitious ...

Nano-silica enhanced liquid-crystalline composite gels [PDF]

open access: yesChinese Science Bulletin, 2016
Soft micro-environment is one of the most important requirements for fast responses of liquid crystals (LCs) to external stimuli; however, the drawback of poor mechanical properties for LCs limits their further applications. In this work, the storage modulus ( G ′) of the LC physical gels, nematic 4-pentyl-4′-cyanobiphenyl (5CB) and 1,3:2,4-di- O ...
