Preparation of Superparamagnetic Fe₃O₄ Nanoparticles from Iron Sand Mediated by Soft Template and Their Performance as Antibacterial Agent

Exploring the role of Mn2+ in the structure, magnetic properties, and radar absorption performance of MnxFe3−xO4–DEA/MWCNT nanocomposites

“…This functional group facilitates the combination of Mn-Fe 2 O 4 with MWCNT. 15,38 Our obtained vibrations are similar to the vibrational peak of O-H reported in previous studies, specically those at 3321, 25 3420, 38 and 3430 cm −1 . 15 We also detected the C-O functional groups at 2325 and N-H at 733, 1143, and 3288 cm −1 , respectively.…”

This nding suggests that the DEA used in nanoparticle preparation has not evaporated.…”

“…Diethylamine (DEA) is one of the capping agents serving as a so template for improving the size and shape of NPs to minimize agglomeration, which is also important to boost the absorption ability. 15,16 The performance of Fe 3 O 4 NPs in radar absorption can be improved through compositing and substitution with other materials. Recently, carbon nanotubes (CNTs) have gained attention as composite materials with Fe 3 O 4 NPs owing to their a Department of Physics, Faculty of Mathematics and Natural Science, State University of Malang, Jl.…”

Synthesis and characterisation of Fe3O4/MWCNT/ZnO nanocomposites covered by a soft template as a new antibacterial agent

“…To overcome this problem, this study proposes covering nanoparticles with diethylamine as a soft template. Our previous research showed that the addition of diethylamine to Fe 3 O 4 effectively improves the uniformity of nanoparticle shape and size and reduces their agglomeration rate [40].…”
