The digitalization of the society in context Internet Things (IoT) demands a new generation sustainable materials and processes to reduce environmental impact technological advances. This work reports on multifunctional nanocomposites based carrageenan magnetic cobalt ferrite (CoFe2O4-CFO) nanoparticles, processed by direct-ink-writing their applicability as actuators. exhibit compact morpholog...

Owing to their unique characteristics, multiferroic materials are expected be widely used in the next-generation multifunctional devices. In addition improving developing affordable fabrication processes for is highly demanded both industry and academia. this paper, we show a novel process named electric-assisted magnetophoretic deposition of nanotube array-based nanocomposite films. Magnetic n...

Glycerol mono-oleate (GMO) was produced by direct esterification reaction with amberlyst 16 resin catalysts with the efficiency of 86% and was used as a surfactant for synthesis of CoFe2O4 nano-particles by surfactant-assisted microwave method. Fourier transform infrared spectroscopy (FT-IR), X-Ray diffraction (XRD) and scanning electron microscopy (SEM) were used to consider the structural and...

Nanoparticles of CoGdxFe2 ? xO4 (x = 0%, 25%, 50%) synthesized via sol–gel auto combustion technique and encapsulated within a polymer (Eudragit E100) shell containing curcumin by single emulsion solvent evaporation were formulated in this study. Testing nanoparticles was carried out using different characterization techniques, to investigate composition, crystallinity, size, morphology, surfac...

a carrier system based on nanoporous silica (sba-15) with magnetic nanoparticles of cofe2o4 was synthesized via the impregnation of cobalt salt, iron salt and citric acid with as-synthesized sba-15. the obtained samples were characterized by small angle x-ray scattering (saxs), n2 adsorption/desorption, scanning electron microscopy (sem), vibrating sample magnetometer (vsm) and ultraviolet (uv)...

Complex oxide nanocrystals with a spinel structure show their remarkable optical, electronic, mechanical, thermal, and magnetic properties. In this study, we present a simple yet versatile strategy to grow selfassembled epitaxial CoFe2O4 nanocrystals with well-controlled size (less than 10 nm) and single orientation. CoFe2O4 nanocrystals were fabricated via phase separation in a BiFeO3–CoF2O4 u...

Sulfonated-silica-coated cobalt ferrite (CoFe2O4) magnetic nanoparticles (MNPs-SiCoFe-SO3H) are efficient heterogeneous catalysts for the synthesis of 3,4-dihydropyrimidin-2(1H)-one and octahydroquinazoline derivatives in absence solvent. The effects solvent, temperature, catalyst amount on reaction investigated. easy separation, reusability catalyst, simplicity procedure, mild conditions, good...

Recycling and reusing spent lithium-ion batteries (LIBs) have gained a lot of attention in recent years, both ecologically commercially. The carbon nanotube-loaded CoFe2O4 (CoFe2O4@CNTs) composite was made using solvothermal technique utilizing wasted LIBs as the starting material nanotubes support, it used an efficient peroxymonosulfate (PMS, HSO5−) activator to degrade chloroquine phosphate (...
