Influence of temperature on structural, magnetic and thermal properties of superparamagnetic MnFe2O4 nanoparticles

Magnetic nanocrystalline MnFe2O4 nanoparticles with spinel structure were synthesized using co-precipitation technique and the effect of annealing temperature on physicochemical properties were studied using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Vibrating sample magnetometer (VSM), and Thermogravimetric analysis (TGA). XRD confirmed the formation of single-phase cubic spinel structures with crystallite sizes ranging from 11.45 to 16.05 nm. FTIR revealed the formation of spinel ferrite nanoparticles with oleic acid binding. TGA demonstrated the formation of pure MnFe2O4 nanoparticles with improved crystalline structure at 300 °C, which developed secondary phases on annealing at 500 °C followed by cation redistribution at tetrahedral and octahedral sites at 700 °C. The heat treatment decreased the saturation magnetization from 15.85 emu/g to 14.30 emu/g which eventually increased to 14.83 emu/g. All the prepared nanoparticles showed superparamagnetic behavior. The results obtained from all the analyses support each other.

Mechanical Performance and Thermal Stability of Hardened Portland Cement -Recycled Sludge Pastes Containing Mnfe2o4 Nanoparticles

Enhanced electrochemical activities of morphologically tuned MnFe2O4 nanoneedles and nanoparticles integrated on reduced graphene oxide for highly efficient supercapacitor electrodes.

The morphology of a nanoparticle strongly controls the path of electronic interaction, which directly correlates with the physicochemical properties and also the electrochemical comportment. Combining it with a two-dimensional (2D) material for a layer-by-layer approach will increase its possibilities in applications such as energy conversion and storage. Here, two different morphologies of MnFe2O4, nanoparticles and nanoneedles, are developed by a facile hydrothermal approach and sandwiched with reduced graphene oxide for constructing a 2D/3D sandwiched architecture. The rGO planar structure with abundant hierarchical short pores facilitates the thorough utilization of the utmost surface area to permeate the electrolyte within the structure to minimize the accumulation of rGO nanosheets laterally. The ferrite composited with rGO manifests high specific capacitance as the EDLC behaviour surpasses the faradaic pseudocapacitance boosting electrical conductivity compared to the as-synthesized MnFe2O4 structures. Benefiting from a 3D structure and the synergetic contribution of the MnFe2O4 nanoneedles and electrically conductive rGO layer, the MnFe2O4 nanoneedles@rGO electrode exhibits a high areal capacitance of 890 mF cm−2 and a remarkable specific capacitance of 1327 F g−1 at a current density of 5 mA cm−2. 93.36% of the initial capacitance was retained after 5000 cycles in 1 mol L−1 Na2SO4 indicating its high cycling stability. The synthesis route proves to be beneficial for a comprehensive yield of MnFe2O4@rGO nanosheets of different morphologies for use in the sophisticated design of energy-storing devices. This research strongly suggests that nanoparticle geometry, in addition to two-dimensional carbon-based materials, is a critical factor in a supercapacitor design.

Impact of temperature-induced oxygen vacancies in polyhedron MnFe2O4 nanoparticles: As excellent electrochemical sensor, supercapacitor and active photocatalyst

Here, we investigate the effect of temperature on solution combustion synthesized MnFe2O4 nanoparticles (NPs) as supercapacitor electrode material that would affect the structural, optical, electrochemical, magnetic and sensing properties. The variation in temperature influences the structure and morphology of synthesized NPs which in turn produces defect states in NPs. Powder X-ray diffraction studies confirms the presence of cubic spinel structure with increase in crystallinity and crystallite size with increase in temperature. Scanning electron microscopy analysis indicates the morphology change in NPs from spherical to network like interlinking to the formation of polyhedron structure at higher temperature. Photoluminescence, energy dispersive X-ray analysis, X-ray photoelectron scpectroscopy and UV-visible diffused reflectance spectroscopy studies emphasize the increase in surface oxygen vacancies concentration with narrowing of band gap from 2.9 to 2.5 eV. Electrochemical studies designate the excellent performance and desirable cyclic stability of synthesized NPs. In particular, the specific capacitance of synthesized NP increases with increase in temperature, reaching highest specific capacitance from CV was 297.7 F/g for 0.1 M HCl and 158.85 F/g for 0.1 M NaNO3 electrolytes for NP synthesized at 500 °C. The synthesized NPs show excellent stability with high capacity retention in both the electrolytes. The graphite modified electrode can also sense Paracetamol and d-Glucose at a very low concentration of 1–5 mM. Meanwhile, it acts as a very good photocatalyst to decolourize Methylene Blue and Alizarin Red S dye under Sunlight illumination due to the increase in concentration of surface oxygen vacancies with narrow band gap. Finally, the synthesized MnFe2O4 NP can be used as a potential supercapacitor electrode with excellent stability and recyclability, to sense the analyte even at very low concentration and also act as a photocatalyst with high recyclability with the help of magnetic nature towards environmental cleaning.

MnFe2O4 saturable absorber for nanosecond Q-switched fiber laser

Low-dimensional (LD) materials show the extraordinary properties and have led to applications in the fields of photonics, optoelectronics and energy. As a kind of zero-dimensional (0D) transition metal oxides, MnFe2O4 nanoparticles possess various magneto-optical properties. However, the nonlinear optical characteristics as well as the applications in pulsed lasers have never been studied so far. Herein, the MnFe2O4 nanoparticles with diameter of 10 nm were synthesized by the thermal decomposition method. The MnFe2O4-microfiber device was prepared by depositing MnFe2O4 nanoparticles on a microfiber, whose saturation intensity/modulation depth was measured to be 16.68 MW/cm2/19.64%. Furthermore, this MnFe2O4-microfiber device was used to generate passively Q-switching laser pulses in Er-doped fiber (EDF) laser. Under the pump power of 80–780 mW, the pulse duration/repetition rate varies from 4.76 μs/73.1 kHz to 622 ns/230.9 kHz. The largest output power is 29.75 mW. The 70 dB signal-to-noise ratio (SNR) verifies the stability of Q-switching operation. This work is the first demonstration of using MnFe2O4 nanoparticles as saturable absorber (SA) in designing Q-switching laser. Compared to recent reported Q-switching EDF lasers with LD materials, our work shows some improvements. These experimental results demonstrate that MnFe2O4 nanoparticles can be developed as an efficient SA materials and have potential photonics applications.

Excellent, Lightweight and Flexible Electromagnetic Interference Shielding Nanocomposites Based on Polypropylene with MnFe2O4 Spinel Ferrite Nanoparticles and Reduced Graphene Oxide.

In this work, various tunable sized spinel ferrite MnFe2O4 nanoparticles (namely MF20, MF40, MF60 and MF80) with reduced graphene oxide (RGO) were embedded in a polypropylene (PP) matrix. The particle size and structural feature of magnetic filler MnFe2O4 nanoparticles were controlled by sonochemical synthesis time 20 min, 40 min, 60 min and 80 min. As a result, the electromagnetic interference shielding characteristics of developed nanocomposites MF20-RGO-PP, MF40-RGO-PP, MF60-RGO-PP and MF80-RGO-PP were also controlled by tuning of magnetic/dielectric loss. The maximum value of total shielding effectiveness (SET) was 71.3 dB for the MF80-RGO-PP nanocomposite sample with a thickness of 0.5 mm in the frequency range (8.2–12.4 GHz). This lightweight, flexible and thin nanocomposite sheet based on the appropriate size of MnFe2O4 nanoparticles with reduced graphene oxide demonstrates a high-performance advanced nanocomposite for cutting-edge electromagnetic interference shielding application.

Fabrication of MnFe2O4 and Ni: MnFe2O4 nanoparticles for ammonia gas sensor application

Manganese ferrites (MnFe2O4) and three different weight percentage of nickel doped manganese ferrites (Ni: MnFe2O4) was prepared through a chemical co-precipitation method. The crystal structure, crystallite size, and phase of the prepared materials are determined by X-Ray Diffraction technique (XRD). The average crystallite size was calculated to be 44 nm, 42 nm, 37 nm, and 35 nm for MnFe2O4, Ni1%Mn(x−1%) Fe2O4, Ni3%Mn(x−3%)Fe2O4, and Ni5%Mn(x−5%)Fe2O4, respectively. Fourier Transforms Infrared (FTIR) spectroscopy technique is used to study the functional groups present in the prepared materials. Surface morphology and elemental compositions of the synthesized nanoparticles were examined using Scanning Electron Microscope (SEM) and Energy Dispersive X-ray spectroscopy (EDAX). The gas sensing property of the prepared materials was studied with different ppm of ammonia gas (NH3), and the respective response and recovery time was calculated.

Manganese Ferrite Nanoparticles (MnFe2O4): Size Dependence for Hyperthermia and Negative/Positive Contrast Enhancement in MRI.

We synthesized manganese ferrite (MnFe2O4) nanoparticles of different sizes by varying pH during chemical co-precipitation procedure and modified their surfaces with polysaccharide chitosan (CS) to investigate characteristics of hyperthermia and magnetic resonance imaging (MRI). Structural features were analyzed by X-ray diffraction (XRD), high-resolution transmission electron microscopy (TEM), selected area diffraction (SAED) patterns, and Mössbauer spectroscopy to confirm the formation of superparamagnetic MnFe2O4 nanoparticles with a size range of 5–15 nm for pH of 9–12. The hydrodynamic sizes of nanoparticles were less than 250 nm with a polydispersity index of 0.3, whereas the zeta potentials were higher than 30 mV to ensure electrostatic repulsion for stable colloidal suspension. MRI properties at 7T demonstrated that transverse relaxation (T2) doubled as the size of CS-coated MnFe2O4 nanoparticles tripled in vitro. However, longitudinal relaxation (T1) was strongest for the smallest CS-coated MnFe2O4 nanoparticles, as revealed by in vivo positive contrast MRI angiography. Cytotoxicity assay on HeLa cells showed CS-coated MnFe2O4 nanoparticles is viable regardless of ambient pH, whereas hyperthermia studies revealed that both the maximum temperature and specific loss power obtained by alternating magnetic field exposure depended on nanoparticle size and concentration. Overall, these results reveal the exciting potential of CS-coated MnFe2O4 nanoparticles in MRI and hyperthermia studies for biomedical research.

Uptake of anionic and cationic dyes from water using natural clay and clay/starch/MnFe2O4 magnetic nanocomposite

The present research was designed to explore the adsorption of sunset yellow (SY) and Nile blue (NB) from water using clay and clay/starch/MnFe2O4 magnetic composite. The magnetic composite was synthesized by chemical precipitation and the physical-chemical characteristics of the adsorbents were evaluated. The specific magnetic saturation values for MnFe2O4 nanoparticles and clay/starch/MnFe2O4 were obtained 31.88emu/g and 10.33emu/g, respectively. In the batch mode experiments, the effect of operational factors was studied. The pseudo-second-order had a better correlation coefficient compared to the pseudo-first-order, Elovich, and intraparticle diffusion models. The Langmuir and Freundlich model fitted the equilibrium data for adsorption of both dyes (SY and NB) using clay and clay/starch/MnFe2O4, respectively. The maximum adsorption capacity for the adsorption of SY and NB dyes using clay was 67.82 mg/g and 72.25 mg/g, respectively and these values increased by about 15% after using the clay/starch/MnFe2O4 composite. The negative value of Gibbs free energy and enthalpy parameters proved that the SY and NB adsorption is spontaneous and exothermic. A sample of textile wastewater was properly treated using adsorbents. Finally, clay and clay/starch/MnFe2O4 magnetic composite can be used as viable adsorbents for dyes removal from water and industrial wastewater.

Mesoporous ferromagnetic manganese ferrite nanoparticles for enhanced visible light mineralization of azoic dye into nontoxic by-products

In this study, a one pot facile synthesis of ferromagnetic manganese ferrite nanoparticles (MnFe2O4) was carried out using chemical co-precipitation method for mineralization of azo dye (Congo red (CR)) in aqueous solution under visible light irradiation. The synthesized MnFe2O4 nanoparticles were highly crystalline and showed face-centred cubic (FCC) structure with average particle size of 58 ± 4 nm. The BET analysis of the MnFe2O4 nanoparticles revealed the mesoporous distribution of material with high surface area can provide large electro active sites and short diffusion paths for the transport of ions which plays a vital role in the photocatalytic degradation of CR. The point of zero charge (pHPZC) was observed to be 6.7 indicating favourable condition for material-anionic dye interaction. The XPS studies revealed that the large amounts of oxygen vacancies were produced due to the defects in the lattice oxygen. The MnFe2O4 nanoparticles mineralised 98.3 ± 0.2% of 50 mg/L CR within 30 min when tested in photocatalytic reactor under 565 nm. The particles were recoverable under the influence of an external magnet after the photocatalytic reaction and were reusable. The recovered nanoparticles showed 96% of CR degradation efficiency even after five cycles of reuse. The by-product analysis with GC–MS indicated mineralization of CR into simple alcohols and acids. The aqueous solution containing mineralised CR was nontoxic to Trigonella foenumgraecum and Vigna mungo seeds and favoured increased germination, plumule and radicle length when compared to untreated CR.

Development of new superparamagnetic materials with narrow size distribution is crucial for biomedical and environmental applications. Hence, we report the synthesis of narrow size distributed single grain MnFe2O4 nanoparticles of average particle size 9 nm by solvothermal reflux method. Synthesized compound crystallized in face centered cubic spinel structure and is confirmed by X-ray diffraction profiles. Transmission electron micrograph shows narrow size distributed particles with an average particle size of 9 nm and is equal to crystallite diameter estimated from Scherrer equation. The spinel crystal structure is further confirmed by electron diffraction profiles, Fourier transformed infrared spectrum, and Raman spectrum at room temperature. Magnetic properties of the sample show superparamagnetic nature at room temperature with moderate saturated magnetization of 56.4 emug−1. Magnetic heating properties of nanoparticles dispersion show the attainment of hyperthermia temperature (43 °C) in a short span of time of 1.6 min for 2 mg/mL and 2.6 min for 1 mg/mL concentrations. Estimated specific heat generation rate or specific power absorption rate, from temporal temperature plots, is 145.78 Wg−1 and is useful for magnetic hyperthermia application in cancer therapy. Photocatalysis properties of sample show 96% of rhodamine B dye degradation in little less than 6 h under UV light irradiation and are useful for photocatalytic applications in wastewater treatment in industries.

MnFe2O4 nanoparticles promoted electrochemical oxidation coupling with persulfate activation for tetracycline degradation

To enhance the performance of electrochemical oxidation (EO), MnFe2O4 nanoparticles was synthesized and added to the EO system with persulfate (PS) for the tetracycline (TC) degradation. The MnFe2O4 could not only be the catalyst, but also act as the three-dimensional electrode in the electrocatalysis, improving the PS activation and TC elimination. The fabricated nanomaterial was examined through X-ray diffraction, scanning electron microscopy, N2 adsorption isotherms, and X-ray photoelectron spectroscopy to explore its crystal structure, surface morphology, pore structure, and element valences, respectively. The EO/PS-MnFe2O4 system achieved 86.23% TC removal after 60 min treatment, verifying that the synergy had an excellent ability for the TC decontamination compared with other controlled tests. The effect of experimental parameters (MnFe2O4 dose, current density, PS dosage, and original pH) on the TC elimination was determined, and the catalyst displayed a favorable stability and recyclability in consecutive five cycles. The scavenging examination result proved that sulfate and hydroxyl radicals both worked for the antibiotic removal. The possible decomposition pathway was proposed based on the determination of high-performance liquid chromatography mass spectrometer for the TC degradation intermediates.

MnFe2O4 nanoparticles anchored on the surface of MgAl-layered double hydroxide nanoplates for stable magnetorheological fluids

In the present study, the manganese ferrite (MnFe2O4) nanoparticles were controllably anchored on the surface of MgAl-layered double hydroxide (MgAl-LDH) using a facile two-step hydrothermal method, and the as-prepared MnFe2O4/MgAl-LDH nanocomposites were adopted as the magnetic dispersed phase to prepare a stable and uniform magnetorheological (MR) suspension. The obtained MnFe2O4/MgAl-LDH nanocomposites were deeply characterized by XRD, TEM, XPS, BET and SQUID, and the viscoelastic properties of MnFe2O4/MgAl-LDH based MR fluid were investigated in detail under the action of different magnetic fields. More importantly, the results of sedimentation tests showed that the sedimentation stability of MnFe2O4/MgAl-LDH based MR fluid was much higher than that of carbonyl iron (CI) particles based MR fluid. The improved sedimentation stability can be attributed to the special plate-like structure, high specific surface area and reduced density difference.

Tailoring the Design of a Lanthanide Complex/Magnetic Ferrite Nanocomposite for Efficient Photoluminescence and Magnetic Hyperthermia Performance.

In this work, we have designed a magnetoluminescent nanocomposite as a single platform for optical imaging and safe magnetic hyperthermia therapy by optimizing the composition of magnetic nanoparticles and controlling the conjugation strategy of the luminescent lanthanide complex. We have synthesized CoxMn1-xFe2O4 nanoferrites, with x = 0 to 1 in 0.25 steps, from soft (MnFe2O4) to hard (CoFe2O4) ferrites of size (∼20 nm) following a one-pot oxidative hydrolysis method. We have performed the induction heating study with an aqueous dispersion of nanoferrites using an alternating magnetic field (AMF) of 12 kAm-1, 335 kHz. This shows an enhancement of heating efficiency with the increment of manganese content and attains the highest intrinsic loss power (ILP) of 6.47 nHm2 kg-1 for MnFe2O4 nanoparticles. We have then fabricated a magnetoluminescent nanocomposite employing MnFe2O4 nanoparticles as it shows outstanding heating performance within the threshold limit of AMF (≤5 × 109 Am-1 s-1). A layer-by-layer coating strategy is followed, where a pure silica coating of thickness ∼10 nm on MnFe2O4 nanoparticles is achieved before encapsulation of the luminescent complex of europium(III), 2-thenoyltrifluoroacetone, and 1,10-phenanthroline in the second layer of silica. This is to ensure the optimal distance between the magnetic core and Eu(III)-complex to pertain significant luminescence in the composite (Eu-MnFe2O4). The photoluminescence spectra of an aqueous dispersion of Eu-MnFe2O4 by excitation in the UV region show a narrow and strong emission at 612 nm, which is stable even after 72 h. The induction heating study of an aqueous dispersion of Eu-MnFe2O4 in 12 kAm-1, 335 kHz AMF shows an ILP as 4.02 nHm2 kg-1, which is remarkably higher than the hyperthermia efficiency of reported magnetoluminescent nanoparticles.

RETRACTED: Fabrication of thermostable and reusable nanobiocatalyst for dye decolourization by immobilization of lignin peroxidase on graphene oxide functionalized MnFe2O4 superparamagnetic nanoparticles

In view of the potential applications of immobilized enzymes, partially purified Lignin Peroxidase (LiP) from Pseudomonas fluorescens LiP-RL5 was immobilized on Graphene Oxide functionalized MnFe2O4 nanoparticles (10 nm, synthesized by sol-gel auto-combustion) to fabricate a new hyperactive and thermostable nanobiocatalyst and thereafter characterized by using standard techniques. Immobilized LiP was quite stable at 50 °C with the half-life of 14 h and showed higher tolerance towards various metal ions and solvents than free LiP. Immobilized LiP retained 50% of enzyme activity even after nine consecutive runs. When tested against various textile dyes, the immobilized LiP was found quite effective with higher dye decolourization efficiency (up to 88%) within 1 h of incubation at 30 °C. The results of this research effort confirmed that the immobilization of LiP and fabrication of nanobiocatalyst increase the efficacy, stability, and reusability of the enzyme which could be efficiently utilized under harsh industrial conditions.

HCl and NaOH were used as electrolytes to study the electrochemical behavior of the nanoparticles. The specific capacitance values determined from the CV curves obtained using the MnFe2O4 versus Ag/AgCl electrodes at an AC amplitude of 5 mV and in the frequency range from 1 Hz to 1 MHz in acidic and basic electrolytes with concentrations of 0.1 M were 4.2566 F g−1 and 2.2099 F g−1, respectively. The application of MnFe2O4 as a photocatalyst under ultraviolet light degraded the dyes comprising methylene blue and Drimaren yellow by up to 96% and 7%, respectively. The results obtained in this study verified the potential applications of sonochemically synthesized MnFe2O4 in semiconductors, sensors, and energy storage devices.

Transition metal ferrites are the essential components utilized in the latest modern-day technology and these include greater elements whose oxidation states and ionic radii are important for exploring their magnetic, optical, structural, and electrochemical properties. The present investigation was targeted on the preparation, physical and electrochemical characterizations of Co-doped MnFe2O4 nanomaterials such as 2 wt% Co-doped MnFe2O4, 4 Wt.% Co-doped MnFe2O4, and 8 Wt.% Co-doped MnFe2O4. More specifically, the study will focus on the techniques which have been employed to raise the specific capacitance of the metal oxides. Electrochemical properties such as cyclic voltammetry (CV), potentiostatic and impedance were used to analyse the super capacitive performance of Co-doped MnFe2O4 electrodes. Based on the outcomes, it is determined that 2 wt% of Co-doped MnFe2O4 has higher super capacitive behaviour than different samples. Precise capacitance for this nanocomposite from GCD was determined to be 551.39 F/g at a current density of 1 mA/cm2. Accordingly, Co-doped MnFe2O4 may be utilized as a promising electrode for energy storage applications. It could be believed that this form of composites indicates excellent capability as electrochemical supercapacitors.

Self-heating evaluation of superparamagnetic MnFe2O4 nanoparticles for magnetic fluid hyperthermia application towards cancer treatment

In the vision of hyperthermia application, high quality superparamagnetic MnFe2O4 nanoparticles (NPs) were synthesized via low cost and environment-friendly co-precipitation method. Thermogravimetric and differential thermal analysis studies confirmed the ferritization temperature at 900 °C. The formation of crystals with a single-phase cubic spinel structure with the Fd3m space group has been confirmed by XRD analysis. SEM-EDX result reveals that the spherical nature of grains with some agglomeration and elemental analysis helps to calculate the atomic percentage of each detected element. An average particle size (~25 nm) was determined by TEM analysis. VSM analysis shows that saturation magnetization (Ms) increases with decreasing temperature in the range 54.18–59.67emu/g at room temperature (300K) to low temperature (5K), respectively, which displays temperature change affects the saturation magnetization and coercivity. FC-ZFC measurements indicated a blocking temperature of NPs around 97.17K. The induction heating study was performed on MnFe2O4 magnetic NPs at 4 kA/m AC magnetic field amplitude and 280 kHz frequency for application in magnetic hyperthermia. The result demonstrates that the heating ability of MnFe2O4 magnetic NPs can be achieved hyperthermia temperature (42 °C) at small content of 0.4 g/mL within 260sec-time duration, which confirms that the prepared material can be used as a heating agent in magnetic hyperthermic treatment. The specific absorption rate (SAR) was found at 217.62 W/g, the obtained result is superior to the previous reports. The obtained results show that the newly synthesized superparamagnetic NPs can act as a promising candidate for hyperthermia therapy due to its high heat-generating capability at lower concentrations with less time period.
