Enhancing photocatalytic dye degradation efficiency through the utilization of shock wave effects on neodymium oxide (Nd2O3)

This article delves into the impact of shockwaves on neodymium oxide (Nd2O3) nanoparticles, aiming to evaluate their physical and chemical stability. Nd2O3 nanoparticles were subjected to varying sets of shock pulses (100, 200, and 300) in photocatalytic dye degradation. The nanoparticles crystallinity and unit cell volume after shockwave exposure were examined using powder X-ray diffraction (PXRD) analysis with unit-cell software. PXRD data revealed no alterations in the crystalline structure, lattice parameter and unit cell volume. Comparisons between pre- and post-shockwave field emission scanning electron microscopy (FE-SEM) portraying data demonstrate that repeated shockwave application causes a decrease in particle size. Raman spectroscopy, under ambient conditions, shows a high intensity after shock conditions intensity will decrease. Furthermore, FTIR spectroscopy revealed the characteristic strong and broad absorption band associated with metal-oxygen (Nd-O) groups in the Nd2O3 nanoparticles. UV–Vis diffuse reflectance spectroscopy (DRS) was used to investigate the bandgap of the Nd2O3 nanoparticles. Initially, the bandgap was measured at 5.96 eV under ambient conditions, but following the shockwave exposure, it was decreased to approximately 5.91 eV. Interestingly, the surface area of the shockwave-treated Nd2O3 nanoparticles is increased and exhibited an increased efficiency in photocatalytic dye degradation. This finding holds promising implications for environmental remediation applications.

The study found that NdMn2O5 nanocomposites possess 754 F/g specific capacitance at 0.5 A/g and concluded superior electrode material properties for supercapacitors compared to the Mn3O4 and Nd2O3 nanoparticles. Moreover, hybrid supercapacitor is employed in as-prepared NdMn2O5 as positive electrode and activated carbon as negative electrode. Assembled hybrid NdMn2O5//AC exhibits 42 Wh/kg specific energy and 379 W/kg power density. 94.34 % of coulombic efficiency and 76.11 % of capacitance retention was perpetuating after 15,000 cycles.

Enhancing the energy storage performance of titanium dioxide electrode material by green doping of Nd2O3 nanoparticles for electrochemical supercapacitors

Doping of sesquioxide alloy onto TiO2 nanomaterials was carried out in a novel green chemistry method using Corallo carpus epigaeus to fabricate the electrodes for pseudocapacitors. The conducted X-ray diffraction studies demonstrated the tetragonal phase of TiO2 and hexagonal phase of Nd2O3 nanomaterials. Morphological analysis revealed the irregular shape of TiO2 materials, each exceeding 100 nm in size, while Nd2O3 materials exhibited a spherical shape within the range of 10–20 nm. Electrochemical investigations unveiled a quasi-rectangular shape in cyclic voltammetric studies and a triangular shape in galvanostatic reactions, suggesting superior electrochemical performance of the electrodes. The doped electrodes exhibited a higher specific capacitance value (785.71 F/g) compared to pure TiO2 (707.14 F/g) at a current density of 1 A/g. These findings affirm the suitability of doped electrode materials for applications in electrical energy storage.

Cerium oxide and neodymium oxide phytoextraction by ryegrass in bioenhanced hydroponic environments

Sustainable technologies for the recovery of rare earth elements (REE) from waste need to be developed to decrease the volume of ore mining extractions and its negative environmental consequences, while simultaneously restoring previously impacted lands. This is critical due to the extensive application of REE in everyday life from electronic devices to energy and medical technologies, and the dispersed distribution of REE resources in the world. REE recovery by plants has been previously studied but the feasibility of REE phytoextraction from a poorly soluble solid phase (i.e., nanoparticles) by different plant species has been rarely investigated. In this study, the effect of biostimulation and bioaugmentation on phytorecovery of REE nanoparticles (REE-NP) was investigated by exposing ryegrass seeds to REE-NP in hydroponic environments. This was studied in two sets of experiments: bioaugmentation (using CeO2 nanoparticles and Methylobacterium extorquens AM1 pure culture), and biostimulation (using CeO2 or Nd2O3 nanoparticles and endogenous microorganisms). Addition of M. extorquens AM1 in bioaugmentation experiment including 500 mg/L CeO2 nanoparticles could not promote the nanoparticles accumulation in both natural and surface-sterilized treatments. However, it enhanced the translocation of Ce from roots to shoots in sterile samples. Moreover, another REE-utilizing bacterium, Bacillus subtilis, was enriched more than M. extorquens in control samples (no M. extorquens AM1), and associated with 52% and 14% higher Ce extraction in both natural (165 μg/gdried-plant) and surface-sterilized samples (136 μg/gdried-plant), respectively; showing the superior effect of endogenous microorganisms’ enrichment over bioaugmentation in this experiment. In the biostimulation experiments, up to 705 μg/gdried-plant Ce and 19,641 μg/gdried-plant Nd could be extracted when 500 mg/L REE-NP were added. Furthermore, SEM-EDS analysis of the surface and longitudinal cross-sections of roots in Nd2O3 treatments confirmed surface and intracellular accumulation of Nd2O3-NP. These results demonstrate stimulation of endogenous microbial community can lead to an enhanced REE phytoaccumulation.

New method of chemical synthesis for nanostructured Nd-Fe-B alloy

A new method of chemical synthesis has been developed for the nanostructured Nd-Fe-B alloy using nanoparticles of Nd2O3, Fe2O3, and Fe3BO6 powders. The nanoparticles of Nd2O3, Fe2O3, and Fe3BO6 were obtained through chemical precipitation followed by calcination. The Nd2O3 nanoparticles have a rod-like shape with a diameter of 28 nm and a length of 118 nm. The α-Fe2O3 nanoparticles have an ellipsoidal shape with an average diameter of 55 ± 11 nm. Additionally, a powder mixture of nanoparticles containing 74.4 wt% α-Fe2O3 and 25.6 wt% Fe3BO6 was obtained, and the particles exhibit an irregular shape with an average diameter of 50 ± 10 nm. A mechanism for the formation of the nanostructured Nd-Fe-B alloy from the Nd2O3, Fe2O3, and Fe3BO6 nanoparticles was proposed. It was found that during the initial stage of the reductive-diffusion process, nanopowders of NdFeO3, NdBO3, and α-Fe2O3 are formed. In the second stage of the reductive-diffusion process, nanopowders consisting of phases of 36.7 wt% Nd2Fe14B, 10.9 wt% α-Fe, and 52.4 wt% CaO are formed. After removing CaO, the obtained nanostructured Nd-Fe-B alloy consists of 76.1 wt% Nd2Fe14B, a hard magnetic phase, and 23.9 wt% α-Fe, a soft magnetic phase. The average particle size of the nanostructured Nd-Fe-B alloy is 110 ± 35 nm. The nanostructured Nd-Fe-B alloy powders exhibit the following magnetic characteristics: coercive force (Hc) of 3295 Oe, saturation magnetization (Ms) of 132.01 A·m2/kg, and residual magnetization (Mr) of 99.53 A·m2/kg.

Coconut shell waste-derived graphene oxide composite with neodymium oxide (Nd2O3) for advanced applications

This paper reports the synthesis and physical properties of graphene oxide/neodymium oxide (GO/Nd2O3) composites. The GO/Nd2O3 composite was prepared by a simple Sonochemical Method, and graphene oxide was synthesized by a modified hummers method. The synthesized composites were characterized by using X-Ray Diffraction (XRD), Fourier Transform Infra-Red (FT-IR), Scanning Electron Microscopy-Energy Dispersive X-ray (SEM-EDX), Raman Spectroscopy, and UV–Vis Spectroscopy. The XRD data confirmed that the GO/Nd2O3 composite had a hexagonal phase structure and showed that the more Nd2O3 nanoparticles were added to GO, the more the crystallinity index increased. The FT-IR spectra showed six types of bonds of functional groups of the GO/Nd2O3 composite, namely the hydroxyl (-OH), carbonyl (C]O), (C]C), (C–O–H), (C–O–C), and the absorption band at 678 cm−1 shows REOs (Nd2O3). Raman spectroscopic analysis showed that the intensity of the ratio of ID/IG was (∼0.85) with the size of sp2 graphitic area of ∼22.6 nm. The addition of Nd2O3 particles to GO did not affect the intensity ratio of ID/IG and was almost the same for the GO and GO/Nd2O3 composite. SEM results show that the composite has a porous three-dimensional carbon network structure. The optical properties were analyzed using UV–Visible spectroscopy. The results of Urbach Energy showed that the GO/Nd2O3 composite is a semiconductor material with an Urbach Energy value of 0.050–0.063 eV, showing the potential application of GO/Nd2O3 composites in electronic devices.

Effects of Nd2O3 Nanoparticles on the Structural Characteristics and Dielectric Properties of PVA Polymeric Films.

Polyvinyl alcohol (PVA) and Neodymium (III) oxide (Nd2O3) were combined to synthesized flexible innovative PVA/Nd2O3 polymer composite samples utilizing a solution casting approach for use in dielectric devices. The XRD, FTIR, and SEM methods are all investigated to characterize the composite films. In a frequency of 50 Hz to 5 MHz, the effects of additive Nd2O3 on the dielectric behavior of PVA were recorded. The PVA/Nd2O3 composite films were successfully fabricated, as shown by XRD and infrared spectroscopy. The scanning microscopy pictures showed that the Nd2O3 was loaded and distributed uniformly throughout the PVA. After the incorporation of Nd2O3, the composite PVA/Nd2O3 has a conductivity of 6.82 × 10-9 S·cm-1, while the PVA has a conductivity of 0.82 × 10-9 S·cm-1. Another improvement is the decrease in the relaxation time from 14.2 × 10-5 s for PVA to 6.35 × 10-5 s for PVA/Nd2O3, and an increase in the dielectric constant of 0.237 for PVA to 0.484 at a frequency of 100 Hz. The results showed that the composite samples have considerable changes as flexible films in different applications, including batteries and electronic circuits.

Biointeraction of cerium oxide and neodymium oxide nanoparticles with pure culture Methylobacterium extorquens AM1

Rare earth elements (REE) are valuable raw materials in our modern life. Extensive REE application from electronic devices to medical instruments and wind turbines, and non-uniform distribution of these resources around the world, make them strategically and economically important for countries. Current REE physical and chemical mining and recycling methods could have negative environmental consequences, and biologically-mediated techniques could be applied to overcome this issue. In this study, the bioextraction of cerium oxide and neodymium oxide nanoparticles (REE-NP) by a pure culture Methylobacterium extorquens AM1 (ATCC®14718™) was investigated in batch experiments. Results show that adding up to 1000 ppm CeO2 or Nd2O3 nanoparticles (REE-NP) did not seem to affect the bacterial growth over 14-days contact time. Effect of methylamine hydrochloride as an essential electron donor and carbon source for microbial oxidation and growth was also observed inasmuch as there was approximately no growth when it does not exist in the medium. Although very low concentrations of cerium and neodymium in the liquid phase were measured, concentrations of 45 μg/gcell Ce and 154 μg/gcell Nd could be extracted by M. extorquens AM1. Furthermore, SEM-EDS and STEM-EDS confirmed surface and intracellular accumulation of nanoparticles. These results confirmed the ability of M. extorquens to accumulate REE nanoparticles.

Multifunctional Nd2O3/CNFs Composite for Microwave Absorption and Anti-Corrosion Applications

To improve the limitations of traditional microwave absorbing materials (MAMs), such as high density and narrow absorption bandwidth, neodymium oxide/carbon nanofiber (Nd2O3/CNF) composites were successfully prepared by electrospinning technology combined with a high-temperature carbonization process. The three-dimensional network structure of CNFs provides a path for conducting electromagnetic waves, and its porous structure also increases the multiple reflections of electromagnetic waves in the composite fibers, which significantly attenuates the energy of electromagnetic waves. Additionally rare-earth elements have a unique electronic arrangement on the 4f electron layer. The addition of Nd2O3 can turn the dielectric constant of Nd2O3/CNF and optimize the impedance matching. Also, Nd2O3 nanoparticles (Nd2O3–NPs) resulted in numerous of heterojunction surfaces and introduced the magnetic loss mechanism. Under the combined action of the double loss mechanism, the minimum reflection loss of Nd2O3/CNF composite fiber is −66.7 dB at 9.36 GHz, and the effective absorption bandwidth is 4.4 GHz (7.68–12.08 GHz). The radar cross section simulation results also prove that the composite fibers exhibit strong consumption of electromagnetic waves. Additionally, the excellent flexibility and anticorrosion properties of the composite fibers make them satisfy the multifunctional requirements of MAMs.

Nd2O3, Cr2O3, and V2O3 nanoparticles were prepared by calcining the precursor materials that are novel mixed ligand complexes: [Nd(BDC)(ADMPY)(OAc)].H2O, [Cr(BDC)(ADM PY)Cl].H2O, and [V(BDC)(ADMPY)Cl].H2O, where BDC = 1,4-benzenedicarboxylic acid and ADMPY = 2-amino-4,6-dimethyl pyrimidine. The generated compounds were examined through several techniques such as elemental analysis (C.H.N), UV-Vis spectroscopy, thermal analysis (thermogravimetric, differential thermogravimetry, and differential thermal analysis), FT-IR spectra, X-ray diffraction (XRD), scanning electron microscope (SEM), and transmission electron microscope (TEM). The TEM micrographs showed that neodymium oxide nanoparticles assumed agglomerated platelet-like particles, with particle sizes around 30.16 nm, while chromium oxide NPs showed solid block material with compact density and fewer pores with nearly spherical shape and 56.12 nm size. The vanadium oxide NPs were an agglomeration of small spherical nanoparticles of 28.4 nm size. The antimicrobial properties of the samples were assessed using two strains of Gram-positive bacteria, two strains of Gram-negative bacteria, and one strain of yeast. The antimicrobial results demonstrated that a large spectrum of activity characterizes the tested compounds because they are active on Gram-positive and Gram-negative bacteria, especially on Gram-positive strains. The antioxidant activity of prepared compounds was assessed by scavenging free radicals of DPPH. Metal oxide NPs also showed promising results as antioxidants.

AbstractThe main idea of this research is to synthesize the neodymium oxide (Nd2O3) nanoparticles with a particle size of less than 10 nm and to investigate the influence of leaf extracts of different plants. Leaf extracts of three plants namely Phyllanthus emblica, Citrus limetta, and Citrus paradisi, were used for the fabrication of Nd2O3 via the sol–gel and green synthesis methods, and the mechanism for the synthesis of neodymium oxide has been investigated. All prepared samples were subjected to UV–Visible Spectroscopy, Fourier Transform Infrared spectroscopy (FTIR), Thermogravimetric analysis (TGA), X‐ray diffraction (XRD) analysis, and Scanning Electron Microscopy (SEM) and Energy Dispersive X‐ray (EDX) analysis to study the optical and structural properties. The band gap of the neodymium oxide nanoparticles was observed between 4.45 and 5.26 eV. The bond length of Nd‐O for the neodymium oxide samples as‐synthesized was calculated as 2.18 and 2.24 Å by using FTIR data. Furthermore, kinetic and thermodynamic parameters were calculated using TGA. XRD patterns showed the formation of cubic, monoclinic, and hexagonal structures of Nd2O3. The Nd2O3 nanoparticles were used as photocatalysts for the degradation of methylene blue under irradiation of sunlight, and the maximum percentage degradation of 74.8% was observed.

Multimotion of Marangoni Propulsion Ships Controlled by Two-Wavelength Near-Infrared Light.

Multimode motion of Marangoni propulsion ships on a water surface as per a near-infrared, two-wavelength selective response is achieved for the first time. The ships are rhombus- or propeller-shaped polyacrylamide or siloxane resin-based gels in which Nd2O3 and Yb2O3 nanoparticles are incorporated separately for photothermal conversion at 808 and 980 nm, respectively. The rhombus geometry is for straight locomotion, and the propeller geometry is for rotation. On/off remote control of the forward and backward locomotion of a rhombus-shaped ship and of the clockwise and counterclockwise rotations of a propeller-shaped ship via irradiation with 808 or 980 nm near-infrared light is demonstrated. The nanoparticles are incorporated into the desired locations of the gels, enabling selective local heating of the gels without focusing the light. The temperature gradient of the ships by local heating, based on a photothermal conversion, generates a Marangoni propulsion force to move the ship in the desired direction.

Facile construction of Ag, In2O3, or Nd2O3 nanoparticles (NPs) incorporated mesoporous LaNaTaO3 nanocrystalline using Pluronic F-127 were explored for photocatalytic H2 generation compared to pristine LaNaTaO3 nanocrystalline. The mesoporous LaNaTaO3 was achieved a little H2 generation ~ 40 µmolg−1; however, H2 generation extremely promotes with the incorporation of Ag, In2O3, and Nd2O3 NPs compared to pristine LaNaTaO3. The yield of the H2 generation of Ag/LaNaTaO3 photocatalyst was greater 75 times than pristine LaNaTaO3. A maximum H2 generation ~1755, 2281.5, and 2965.9 µmolg−1 was achieved for Nd2O3, In2O3, or Ag/LaNaTaO3 photocatalysts, respectively. The H2 generation rate for Ag/LaNaTaO3 photocatalyst was calculated to be ~ 329.5 μmolg−1h−1, 110 times greater than that of pristine LaNaTaO3 (3 μmolg−1h−1). The H2 generation rate of Ag/LaNaTaO3 photocatalyst was faster 1.7 and 1.3 times than that either Nd2O3 or In2O3/LaNaTaO3 photocatalysts, respectively, indicating the highly promoted photocatalytic H2 generation of Ag/LaNaTaO3 photocatalyst. The impact of Ag, In2O3, or Nd2O3 NPs on the morphology, crystal structure, optical, photoelectrochemical, photoluminescence measurement of mesoporous LaNaTaO3 nanocrystalline, and their H2 generation in the existence aqueous glycerol solution were studied in detail.

Studies on mechanical properties, dielectric behavior and DC conductivity of neodymium oxide/poly (butyl methacrylate) nanocomposites

The current article aims to develop poly (butyl methacrylate) (PBMA) nanocomposites with enhanced electrical and mechanical properties by incorporating neodymium oxide (Nd2O3) nanoparticles between the PBMA chains. The morphological, thermal and structural profiles of the PBMA nanocomposites reinforced with different loading of Nd2O3 nanoparticles were investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD) and thermogravimetric analysis (TGA). The SEM images revealed that the morphology of the PBMA was significantly influenced by the insertion of Nd2O3. The uniform dispersion of Nd2O3 in the polymer composite was visible at 5 wt% loading of nano-filler. The main crystalline peaks of Nd2O3 nanoparticles in the amorphous PBMA structure were revealed by the X-ray diffraction analysis. The thermal stability of PBMA was greatly enhanced by the dispersion of Nd2O3 in the PBMA matrix. The tensile strength and elongation at break of the composites were measured and both results showed the enhanced mechanical properties of PBMA due to the reinforcement of Nd2O3 nanoparticles. The various parameters affecting the increased tensile strength of composite by the incorporation of nanoparticles were studied by different theoretical modeling. The electrical properties such as dielectric constant and the dielectric loss tangent (tan δ) of PBMA nanocomposites were enhanced with the addition of nanoparticles. Also, the DC conductivity of polymer composites was estimated and the applicability of different theoretical models for predicting the conductivity properties of PBMA/Nd2O3 nanocomposites were examined.

Synthesis, Characterization, Thermal Properties and Temperature-Dependent AC Conductivity Studies of Poly (Butyl Methacrylate)/Neodymium Oxide Nanocomposites

Thermoplastic nanocomposites based on poly (butyl methacrylate) (PBMA) with various contents of neodymium oxide (Nd2O3) nanoparticles were synthesized through one-step free radical polymerization method. The structural, morphological and thermal properties of the nanocomposites were studied by Fourier transform infrared (FTIR) spectroscopy, ultraviolet (UV)–visible spectroscopy, high-resolution transmission electron microscopy (HRTEM), scanning electron microscopy (SEM) and thermogravimetry and differential scanning calorimetry (DSC). The effect of different volume fraction of Nd2O3 nanoparticles on temperature-dependent AC conductivity of polymer nanocomposites was also analysed. The FTIR and UV spectra confirmed the incorporation of Nd2O3 nanoparticles in PBMA chain through the shift in characteristic absorption bands of nanocomposite compared to pure PBMA. TEM images indicated that Nd2O3 nanoparticles were sheathed by PBMA chain. The SEM images revealed better compatibility between the PBMA and Nd2O3 nanoparticles. The thermal transition studied by DSC showed an enhanced glass transition temperature of PBMA by the inclusion of Nd2O3 nanoparticles. Similarly, the thermal degradation of the composite was elevated by the insertion of nanoparticles. The AC conductivity of nanocomposite was higher than pure PBMA and the electrical conductivity increased with the temperature and frequencies. The activation energy and exponential values of the composite revealed that the system follows small polaron hopping mechanism.
