Autor: Yulia Eka Putri, Tio Putra Wendari, Dinda Dinda, Meyrizka Arnel, Humaira Faradilla, Refinel Refinel, Mai Efdi

Publikováno v: Case Studies in Chemical and Environmental Engineering, Vol 9, Iss , Pp 100601- (2024)

SrTiO3 hydrothermal synthesis mediated by cetyl trimethyl ammonium bromide (CTAB) and tert-butyl amine (TBA), resulted in a typical nanopolyhedral morphology. All samples were identified as single-phase, adopting a Pm3m cubic crystal structure. Morph

Pseudomonas aeruginosa antibacterial textile cotton fiber construction based on ZnO–TiO2 nanorods template

Autor: Yetria Rilda, Doni Damara, Yulia Eka Putri, Refinel Refinel, Anthoni Agustien, Hilfi Pardi

Publikováno v: Heliyon, Vol 6, Iss 4, Pp e03710- (2020)

An alternative method of synthesizing ZnO–TiO2 nanorods is through route precipitation and sintering at 600 °C. In this study, the introduction of Ti into Zn in the molar ratio Ti:Zn (1:3) produced a composite ZnO-Low TiO2 (ZnO-LTiO2) while 1:1 pr
