TL;DR: It is concluded that the addition of surfactant, especially rarasaponin, can effectively improve the loading of AgNPs onto hydrogel-dressing via adsorption and promote the antibacterial activity.
Journal ArticleDOI
Studies on the performance of bentonite and its composite as phosphate adsorbent and phosphate supplementation for plant.
Artik Elisa Angkawijaya,Shella Permatasari Santoso,Shella Permatasari Santoso,Vania Bundjaja,Felycia Edi Soetaredjo,Felycia Edi Soetaredjo,Chintya Gunarto,Aning Ayucitra,Yi-Hsu Ju,Alchris Woo Go,Suryadi Ismadji,Suryadi Ismadji +11 more
TL;DR: Performance of AAB and OrB as Pi-supplementation was assessed based on growth phenotypes of Arabidopsis thaliana; seedlings show that supplementation of Pi@AAB and Pi@OrB (at half doses) can promote primary root extension and demonstrate the safety of direct disposal of the materials into the soil.
Journal ArticleDOI
TiO2/guar gum hydrogel composite for adsorption and photodegradation of methylene blue.
Shella Permatasari Santoso,Shella Permatasari Santoso,Artik Elisa Angkawijaya,Vania Bundjaja,Chang-Wei Hsieh,Alchris Woo Go,Maria Yuliana,Hsien-Yi Hsu,Phuong Lan Tran-Nguyen,Felycia Edi Soetaredjo,Felycia Edi Soetaredjo,Suryadi Ismadji,Suryadi Ismadji +12 more
TL;DR: In this article, a composite hydrogel from the combination of guar gum (a neutral galactomannan polysaccharide) and TiO2 was used to remove methylene blue through adsorption and photodegradation.
Journal ArticleDOI
Saponin-intercalated organoclays for adsorptive removal of β-carotene: Equilibrium, reusability, and phytotoxicity assessment
