Phosphine-functionalized Fe3O4/SiO2/composites as efficient magnetic nanoadsorbents for the removal of palladium ions from aqueous solution: Kinetic, thermodynamic and isotherm studies

MAPLE Processed Nanostructures for Antimicrobial Coatings

“…After 500 °C, the sample loses 0.47% of its mass, the magnetic residue, representing 70.00%. The lack of the sharp exothermic effect within this temperature interval, specific for the phase transition of maghemite to hematite, indicates the presence of the SiO 2 shell on the nanoparticle’s surface and confirms its protective role and thermal stabilizing effect for nano-magnetite [ 56 , 57 ].…”

Synthesis of nano-β-CD@Fe3O4 magnetic material and its application in ultrasonic treatment of oily sludge

“…The key to achieving the deconstruction and destruction of oily sludge is to achieve the stripping of the oil phase and water, oil phase and solid phase [10] . Nano-β-CD@Fe 3 O 4 can be adsorbed at the oil–water interface and oil-solid interface and realize the enrichment at the interface, which provides powerful conditions for the cavitation of ultrasound [17] , [22] .…”

Insight into core -shell microporous zinc silicate adsorbent to eliminate antibiotics in aquatic environment under the COVID-19 pandemic

“…The three peaks at 1101 cm −1 , 955cm −1 and 467 cm −1 belong to the asymmetric stretching, symmetric stretching and asymmetric deformation vibrations of Si–O–Si, respectively ( Huang et al, 2017 ; Wang et al, 2022 ). The narrow peak at 798 cm −1 is usually attributed to the Si–OH stretching vibration in the unique silanol nests ( Naini et al, 2022 ). In SiO 2 @ZSO, the peak at 663 cm −1 is attributed to the asymmetric stretching vibration model of Zn–O ( Saberi Rise et al, 2022 ).…”
