A study of solid-state epimerisation within lactose powders and implications for milk derived ingredients stored in simulated tropical environmental zones

Isolated from milk, lactose is a food ingredient and an excipient in medicines. Its chiral forms are known to undergo epimerisation in solution but understanding whether this chemical reaction occurs in lactose powders exposed to tropical environments is of great importance for medicine stability and food quality. Thus, the aim of this study was to investigate epimerisation within lactose powders stored under specified conditions that model hot and humid climates. Powdered α-lactose monohydrate was stable under all conditions, whereas β-lactose stored at 40 °C and 75 % RH suffered epimerisation, falling to 3.9 ± 0.3 β-content after 6-months. Zero-order kinetics observed by NMR, indicated a shelf-life (5 % degradation) of 4.55-days for β-lactose containing powders. Thermal analysis revealed monohydrate formation as β-lactose epimerised, seen as tomahawk shaped α-lactose monohydrate crystals by SEM. Therefore, it is recommended β-rich lactose containing powders, e.g., infant formula or direct compression tablet formulations, are stored hermetically in tropical zones.

Crystallization Thermodynamics of α-Lactose Monohydrate in Different Solvents.

It is common to find that some of the lactose in dairy powders and pharmaceutical tablets is present in the unstable amorphous state. Therefore, their crystallization thermodynamics in different solvents are particularly important. In this paper, the solubility of α-lactose monohydrate (α-LM) in 15 mono-solvents such as ethanol, isopropanol, methanol, 1-propanol, 1-butanol, 2-butanol, isobutanol, 1-pentanol, isoamylol, 1-hexanol, 1-heptanol, 1-octanol, propanoic acid, acetonitrile, and cyclohexanone was evaluated by using the gravimetric method in the temperature ranges from 274.05 K to 323.05 K at constant pressure (1 atm). In the given temperature range, the solubility of α-LM in these solvents increased with the rising of temperature, the highest solubility of α-LM was found in methanol (2.37 × 104), and the lowest was found in 1-hexanol (0.80 × 105). In addition, the increase of α-LM solubility in isopropanol was the largest. The sequence at 298.15 K was: methanol > 1-butanol > isopropanol > ethanol > 1-propanol > 1-heptanol > isobutanol > propionic acid > 1-pentanol > 1-octanol > acetonitrile > isoamylol > 2-butanol > cyclohexanone > 1-hexanol. Solvent effect analysis shows that the properties of α-LM are more important than those of solvents. The Apelblat equation, λh equation, Wilson model, and NRTL model were used to correlate the experimental values. The root-mean-square deviation (RMSD) and relative average deviation (RAD) of all models were less than 2.68 × 10−2 and 1.41 × 10−6, respectively, implying that the fitted values of four thermodynamic models all agreed well with the experimental values. Moreover, the thermodynamic properties of the dissolution process (i.e., dissolution Gibbs free energy (ΔdisG), molar enthalpy (ΔdisH), and molar entropy (ΔdisS)) for α-LM in selected solvents were determined. The results indicate that ΔdisH/(J/mol) (from 0.2551 to 6.0575) and ΔdisS/(J/mol/K) (from 0.0010 to 0.0207) of α-LM in these solvents are all positive, and the values of ΔdisH and ΔdisS. ΔdisG/(J/mol) (from −0.0184 to −0.6380) are all negative. The values were observed to decrease with rising temperatures, implying that α-LM dissolution is an endothermic, entropy-driven, and spontaneous process. The solid–liquid equilibrium data and dissolution thermodynamics of α-LM were obtained, which provide a basis for industrial production.

Terahertz Spectroscopic Analysis of Lactose in Infant Formula: Implications for Detection and Quantification.

Lactose plays a significant role in daily lives as a constituent of various food and pharmaceutical products. Yet, lactose intolerance conditions demand low-lactose and lactose-free products in the market. These increasing nutritional claims and labels on food products entail simple and reliable methods of analysis that can be used for meeting quality standards, nutritional claims and legal requirements. In this study, terahertz time–domain spectroscopy (THz-TDS) was employed to analyse α-lactose monohydrate qualitatively and quantitatively in food products. Both absorption spectra and absorption coefficient spectra were investigated for their prediction performance. Regression models for lactose quantification using peak area and height of the absorption peaks 0.53 and 1.37 THz were developed and assessed in infant formula samples. Satisfactory prediction results were achieved in ideal conditions with pure standards, but not in all predictions of infant formula samples. Reasons and further implications are discussed.

Crystallization induced flower-like lactose as potential carriers for dry powder inhaler application

The study documents the flower-like lactose particles as potential carriers to improve Dry Powder Inhaler (DPI) efficiency. The lactose particles (LMx, LMf) are prepared by anti-solvent crystallization and compared with commercial lactose carriers (Inhalac 251; LMc). Formulations of 1.48% w/w drug loading are prepared using salbutamol sulfate (model drug) and different lactose carriers. The carrier properties are correlated with %FPF using principal component analysis. The analytical results confirm LMx is α-lactose monohydrate, LMf comprises α and β-lactose. Time-resolved crystal growth shows that the LMx particle is agglomerated structure while, LMf particle appear as flower-like structure of size (~45.37–63.92 μm) with high surface and aerodynamic properties compared to LMc. The in-vitro aerosolization studies resulted in higher fine particle fraction (%FPF) for formulations with LMx (~33.23%) and LMf (~44.85%) compared to LMc (~23.40%). The high %FPF is mainly attributed to the higher surface roughness, amorphicity, surface energy of engineered lactose carriers.

Mitigating Capacity Decay by Adding Carbohydrate in the Negative Electrolyte of Vanadium Redox Flow Battery

Glucose, sucrose, D(+)-xylose and α-lactose monohydrate are selected as additives relative to the negative electrolyte of Vanadium Redox Flow Battery (VRFB), with the aim of reducing vanadium permeation and improving electrochemical performance to mitigate capacity decay. The results of a charge–discharge test show that the cell with α-Lactose monohydrate in the negative electrolyte exhibits the best capacity retention. The capacity retention of a single cell employing 1 wt% α-Lactose monohydrate in the negative electrolyte was 71% after 30 cycles, which is 41.5% higher than 29.5% of the control group. Correspondingly, adding α-Lactose monohydrate into the negative electrolyte also significantly inhibits vanadium crossover and water transfer. Furthermore, the effects of additives on the performance of the negative electrolyte are studied by thermal stability experiments, cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The stability experiments indicate that the introduction of 1 wt% α-Lactose monohydrate can elevate the stability of the negative electrolyte at low temperatures. The electrochemical measurements indicate that V(III) electrolyte with 1 wt% α-Lactose monohydrate obtains superior electrochemical activity and reversibility, which can be ascribed to the fact that the hydroxyl group carried by the additive provides more active sites for the redox reaction. Herein, the study provides a meaningful reference for mitigating the capacity decay of VRFB.

Tabletability and compactibility of α-lactose monohydrate powders of different particle size. I. Experimental comparison

In this paper, two types of parameters representing tabletability and compactibility profiles of a series of α-lactose monohydrate powders, ranging in particle size from approximately 3.5 to 203 µm, are derived and compared. By approximating the tabletability profiles using a three-stage model and the compactibility profiles using the Ryshkewitch–Duckworth equation, two compaction rate parameters and two compaction endpoint parameters were derived. The original median particle diameter had generally a strong effect on the tablet tensile strength and hence the tabletability and compactibility profiles. The experimental profiles were well approximated by the models used, and the compaction parameters were regarded as representative of the experimental profiles. The compaction endpoint parameters increased with decreased particle size and were controlled by the same structural feature as the compacts. The tabletability rate parameter also increased with decreased particle size and correlated well with the tabletability endpoint parameter. The compactibility rate parameter tended to increase with decreased particle size, but the effect was limited; moreover, no general correlation was obtained with the compactibility endpoint parameter. It is concluded that compactibility and tabletability parameters collectively provide a concentrated description of the compaction properties of a powder.

Quantification of solid-phase chemical reactions using the temperature-dependent terahertz pulsed spectroscopy, sum rule, and Arrhenius theory: thermal decomposition of α-lactose monohydrate

Transformations of the low-energy vibrational spectra are associated with structural changes in an analyte and closely related to the instability of weak chemical bounds. Terahertz (THz)/far-infrared optical spectroscopy is commonly used to probe such transformation, aimed at characterization of the underlying solid-phase chemical reactions in organic compounds. However, such studies usually provide quite qualitative information about the temperature- and time-dependent parameters of absorption peaks in dielectric spectra of an analyte. In this paper, an approach for quantitative analyses of the solid-phased chemical reactions based on the THz pulsed spectroscopy was developed. It involves studying an evolution of the sample optical properties, as a function of the analyte temperature and reaction time, and relies on the classical oscillator model, the sum rule, and the Arrhenius theory. The method allows one to determine the temperature-dependent reaction rate V1(T) and activation energy Ea. To demonstrate the practical utility of this method, it was applied to study α-lactose monohydrate during its temperature-induced molecular decomposition. Analysis of the measured THz spectra revealed the increase of the reaction rate in the range of V1 ≃ ~9 × 10-4-10-2 min-1, when the analyte temperature rises from 313 to 393 K, while the Arrhenius activation energy is Ea ≃ ~45.4 kJ/mol. Thanks to a large number of obtained physical and chemical parameters, the developed approach expands capabilities of THz spectroscopy in chemical physics, analytical chemistry, and pharmaceutical industry.

Effect of excipient properties and blend ratio on the compression properties of dry granulated particles prepared from microcrystalline cellulose and lactose

In this study, the effect of a systematically varied excipient ratio of a plastic and a brittle material, i.e., microcrystalline cellulose (MCC) and crystalline α-lactose monohydrate (LAC), on the compression properties of dry granulated particles was investigated. Five powders with different MCC:LAC ratios were prepared by dry mixing; subsequently, they were formed into slugs that were milled and sieved, giving granules of two size fractions. Two slugging pressures were used, giving granules of different porosity for each powder. Original powders and granules were compressed, and strain-pressure profiles determined. From these profiles, a series of compression parameters were derived using the Heckel, Kawakita, and Adams compression equations.The initial part of the compression profiles of all granulated powders were similar up to a jamming point, after which the compression profiles diverged depending on the granule composition and the slugging pressure. Parameters derived from the Adams and Kawakita equations reflected the differences in compression behavior, while the Heckel parameter did not. The macroscopic compression stiffening was assessed by the Adams friction parameter which seemed to be controlled by the inner friction of the granules, i.e., their plastic deformation due to inter-particulate flow. The total compressibility, assessed by the Kawakita parameter, was dependent on the initial bulk porosity of the granulations.It is concluded that the composition, microstructure, and packing density of the granules dictated their compression properties, while the granule size and work hardening of primary particles were insignificant.

Insights into the potential of rheological measurements in development of dry powder inhalation formulations

Study of flow is a key to development of dry powder inhalation formulations. Various static (bulk) and dynamic rheological measurements are used to study different aspects of powder flow and packing. Among rheological measurements, the permeability and the fluidization energy are, conceptually, most relevant to dispersion of dry powder inhalation formulations. The aim of the current study was to test the robustness and the range of applications of the two measurements, among other rheological measurements. To this end, we prepared and studied a series of ternary, carrier-based dry powder inhalation formulations. The formulations were mixtures of coarse-fine excipient (α-lactose monohydrate) blends, with different fine excipient concentrations (0.0–15.0 % w/w), and a spray-dried drug (fluticasone propionate) material. The excipient blends were characterized in terms of morphology, size, crystallinity, and rheological properties. The formulations were evaluated in vitro using a low resistance inhalation device, the Cyclohaler®, and a high resistance inhalation device, the Handihaler®. The study design aimed to complement literature data. Bulk rheological measurements, specifically the bulk density, the compressibility, and the permeability, exhibited satisfactory precision and could demonstrate changes in powder composition and structure. They hold a potential for use as critical material attributes to aid monitoring and optimization of carrier-based dry powder inhalation formulations in quality-by-design systems. On the other hand, dynamic rheological measurements, specifically the basic flowability energy, the specific energy, and the fluidization energy, generally exhibited high variability, which obscured interpretation of the measurements and implied heterogeneous powder structures. The fluidization energy could, nevertheless, convey structural changes taking place during powder fluidization.

Investigating sizing induced surface alterations in crystalline powders using surface energy heterogeneity determination

Particle sizing is the most commonly employed and critical unit operation across powder processing industries. In this work, we show the surface energy changes prompted by the sizing operations like milling and sieving in α-lactose monohydrate powders using Finite Dilution Inverse gas chromatography (FD-IGC) analysis. Three separate sieved fractions of α-lactose monohydrate powder were divided into a top, middle and bottom fraction from the same starting material. Similarly, a custom grade α-lactose monohydrate was milled for a different duration to produce two milled samples with different median particle sizes. Sieved sample results showed that the bottom fraction exhibited higher heterogeneity with higher dispersive (γd) surface energy values ranging from 42.5 mJ/m2 to 45.9 mJ/m2 compared to the top and middle fractions. The finest fraction contains more cleaved surfaces that are exposed during the preparation process, i.e. milling, of the material resulting in different surface properties. Furthermore, the surface energy analysis of the milled samples revealed slight but vital differences in the γd heterogeneity profiles. The site-specific distribution of energies was obtained using the Boltzmann probability distribution model and revealed two distinct regions for crystalline α-lactose monohydrate. Thus, our work confirmed that sizing operations like milling and sieving affect the surface energy of the particulate solids due to the changes in properties like size, shape, exposure of internal cleavage planes, etc. and that the surface energy heterogeneity determination using FD-IGC helped in characterising these changes.

Effect of Mixer Type on Particle Coating by Magnesium Stearate for Friction and Adhesion Modification.

Glidants and lubricants are often used to modify interparticle friction and adhesion in order to improve powder characteristics, such as flowability and compactability. Magnesium stearate (MgSt) powder is widely used as a lubricant. Shear straining causes MgSt particles to break, delaminate, and adhere to the surfaces of the host particles. In this work, a comparison is made of the effect of three mixer types on the lubricating role of MgSt particles. The flow behaviour of α-lactose monohydrate, coated with MgSt at different mass percentages of 0.2, 0.5, 1, and 5 is characterised. The mixing and coating process is carried out by dry blending using Turbula, ProCepT, and Mechanofusion. Measures have been taken to operate under equivalent mixing conditions, as reported in the literature. The flow resistance of the coated samples is measured using the FT4 rheometer. The results indicate that the flow characteristics of the processed powders are remarkably similar in the cases of samples treated by Turbula and Mechanofusion, despite extreme conditions of shear strain rate. The least flow resistance of samples is observed in the case of samples treated by the ProCepT mixer. High-velocity collisions of particles round off the sharp corners and edges, making them less resistant to flow. The optimal percentage of magnesium stearate is found to be approximately 1% by weight for all mixer types, as the addition of higher amounts of lubricant does not further improve the flowability of the material.

Modification of soy protein isolate by Maillard reaction and its application in microencapsulation of Limosilactobacillusreuteri

Limosilactobacillusreuteri was encapsulated using Maillard-reaction-products (MRPs) of soy protein isolate (SPI) and α-lactose monohydrate by freeze-drying. The mixed solution of SPI and α-lactose monohydrate was placed in a water bath at 89°C for 160min for Maillard reaction, and then freeze-dried to obtain MRPs. The effects of Maillard reaction on functional characteristics of MRPs and the properties of MRPs-microcapsules were studied. SDS-PAGE indicated that SPI subunit reacted with lactose to form a polymer, and the band of MRPs disappeared around the molecular weights of 33, 40, 63, and 100kDa. Compared with SPI, the emulsion stability, emulsion activity, foaming capacity, foam stability, and gel strength of MRPs were increased by 259%, 55.71%, 82.32%, 58.53%, and 3266%, respectively. The results of Fourier transform infrared spectroscopy, circular dichroism spectroscopy, and scanning electron micrographs confirmed that the protein structure also changed significantly. Then, MRPs were used as wall material to prepare L.reuteri microcapsules. Physical properties and viable counts of L.reuteri during the simulated gastrointestinal digestion and storage period were determined. The particle size of MRPs-microcapsules (68μm) was smaller than that of SPI-microcapsules (91μm). The viable counts of L.reuteri in simulated gastrointestinal digestion and after storage for 30 days were improved. The modifications with Maillard reaction can improve emulsification, foaming, and gel strength of SPI, and MRPs could be used as a new type of wall material in the production of L.reuteri microcapsules.

Stability of α-lactose monohydrate: The discovery of dehydration triggered solid-state epimerization

Lactose is present as an excipient in nearly half of all solid medicines. Despite the assumption of chemical stability, in aqueous solution, the chiral composition of lactose is prone to change. It is not known whether such epimerisation could also occur as solid crystalline α-lactose undergoes thermal desorption of its hydrated water. Thus, the aim of this study was to investigate the anomeric composition of lactose powders after heating in a differential scanning calorimeter. During thermal analysis, the heating cycles were interrupted to allow anomer-composition analysis by NMR. The onset for monohydrate desorption occurred at 143.8 ± 0.3 °C. Post water-loss, at 160 °C for example, α-lactose suffered partial conversion (11.6 ± 0.9%) to the β-anomer. When held at 160 °C for 60 min this increased to 29.7 ± 0.8% β-anomer (p < 0.05). This process of epimerisation was found to be close to zero-order with a rate constant of 0.28% per min−1. Optical microscopy indicated that the solid-state was maintained throughout thermal desorption and up to the onset of melting at 214.2 ± 0.9 °C. Only epimerisation was observed, with no additional chemical degradation detected by NMR. Similar results were observed when heating α-lactose to 190 °C, which resulted in a conversion of 29.1 ± 0.7% to β-lactose. Thus, the exothermic peak observed after monohydrate loss, which has often been attributed to re-crystallisation, comprises a contribution from epimerisation. No epimerisation or hydrate loss was observed for β-lactose powders when heated. In summary, it has been shown unequivocally for the first time that hydrate desorption (dehydration) leads to solid-state epimerisation in α-lactose powders.

Assessing powder flowability at low stresses using ball indentation method: Evaluation of constraint factor

Powders can exhibit different flow behaviour resulting from a combination of physical properties of the material and equipment design. Problems with powder flow are ubiquitous in process industry and become prominent when dealing with fine and cohesive powders. It is therefore of great importance to characterise the flowability of cohesive materials for better process control. Powder flowability is commonly assessed under relatively high preconsolidation loads using shear cell and uniaxial compression methods by which the unconfined yield strength (Y) is evaluated as a function of the applied load. However, these techniques are typically limited to applied stresses greater than 1 kPa and require a relatively large quantity of powder. To overcome these limitations, the recently developed Ball Indentation Method (BIM) is used in this work for assessing powder flow behaviour at low stress levels. The unconfined yield strength (Y) is inferred from the resistance to ball penetration into the surface of a powder bed, based on the method for measurement of hardness (H). This requires the flow resistance, represented by hardness, to be related to the unconfined yield strength by a proportionality factor termed the constraint factor, C, following the analogy with yield stress measurement in continuum solids, i.e. Y=H/C. The constraint factor for silanised glass ballotini, calcium carbonate, α-lactose monohydrate, Avicel and limestone is evaluated and reported here. It is shown that the unconfined yield strength inferred by this method correlates well with those from the uniaxial compression and shear cell measurement. The characterisation of the constraint factor makes it possible to use BIM for powder flowability testing at low stress levels and using a very small powder quantity. This is highly desirable for applications such as capsule filling, tableting and dry powder inhaler devices.

A New Frontier for Nondestructive Spatial Analysis of Pharmaceutical Solid Dosage Forms: Spatially Offset Low-Frequency Raman Spectroscopy.

A new Raman subtechnique, spatially offset low-frequency Raman spectroscopy (SOLFRS), is demonstrated via an analysis of pharmaceutical solid dosage forms. Several different model systems comprised of celecoxib (a popular anti-inflammatory drug), α-lactose anhydrous stable form, α-lactose monohydrate, and polyvinylpyrrolidone (PVP) were used to represent tangible scenarios for the application of SOLFRS. Additionally, the challenges and limitations were highlighted in relation to its real-time use, and potential solutions to address them were also provided. Lastly, the future directions for this new variation of Raman spectroscopic technique were briefly discussed, including its potential for broader application in pharmaceutical analysis and other research fields.

Dual-drug amorphous formulation of gliclazide

Amorphization is a well-established strategy to enhance the dissolution properties of poorly water-soluble drugs. However, the amorphous state is inherently unstable toward recrystallization. Coamorphous systems of a drug and a small-molecule excipient or of two complementary drugs often show an enhanced stability. Diabetes and hypertension are frequently coexistent. In this paper a study on the coamorphization of the poorly water-soluble antidiabetic drug gliclazide (glz) and the antihypertensive drug valsartan (val) is reported. Amorphous glz recrystallized after 1 d under ambient conditions, whereas coamorphous glz-val containing glz and val in a 1:1 or 1:2 molar ratio was stable for at least four months at 20 °C and 56% relative humidity. The dissolution rate of glz increased in the order crystalline glz < glz-val_1:1 < glz-val_1:2. Furthermore, ternary coamorphous systems of glz, val and an excipient were prepared; glz-val_1:1_PVP, glz-val_1:1_HPC, glz-val_1:1_ALM, glz-val_1:1_MCC (PVP = polyvinylpyrrolidone, HPC = hydroxypropyl cellulose, ALM = α-lactose monohydrate, MCC = microcrystalline cellulose). MCC and HPC did not affect the stability of the coamorphous system, while ALM promoted the recrystallization of glz in glz-val_1:1_ALM during storage and freshly prepared glz-val_1:1_PVP contained small amounts of crystalline glz. Glz-val_1:1_MCC showed enhanced dissolution properties compared to crystalline glz and glz-val_1:1 and is a viable fixed-dose formulation.

Computational analysis of triboelectrification due to aerodynamic powder dispersion

Triboelectric charging can strongly influence bulk powder flow behaviour, and hence its characterization is of great interest for safe manufacturing operations. In a recent development, the use of an aerodynamic disperser, employing a pressure pulse to disperse a small powder quantity, shows a great potential for inducing triboelectric charge transfer. We analyse this process by coupled Discrete Element Method and Computational Fluid Dynamics (DEM-CFD) simulations, incorporating triboelectric charge transfer. The simulations are based on property data of glass ballotini as model particles, together with those of α-lactose monohydrate (α-LM) and aspirin, as powders of practical interest. The characteristics of particle-particle and particle-wall collisions are analysed in detail. The analysis shows that pharmaceutical particles charge significantly more than glass ballotini. The charge-to-surface area ratio is remarkably constant and close to its equilibrium value for each test material. Overall, the analysis provides a great insight on the triboelectric charging by aerodynamic dispersion.

Chemical Identification in the Specular and Off-Specular Rough-Surface Scattered Terahertz Spectra Using Wavelet Shrinkage.

We present the development and implementation of a novel wavelet shrinkage technique for the retrieval of obscured characteristic resonant signatures in the scattered terahertz (THz) reflectivity of molecular crystals. In this implementation, the wavelet basis functions associated with the absorption features were identified using the second-order total variation of the wavelet coefficients. Additionally, wavelet coefficients at certain scales were modified using the phase function corrections and wavelet hard thresholding. Reconstruction of the original spectra using these modified wavelet coefficients yielded the exact resonant frequencies of the chemicals, which were otherwise unrecognizable in the spectral artifacts of the rough surface scattering. We examined the robustness of this method over controlled levels of rough surface scattering, validated using the Kirchhoff approximation, in spectroscopic targets made from α-lactose monohydrate and 4-aminobenzoic acid (PABA), which have close spectral lines. We successfully retrieved the spectral absorption fingerprints in both specular and off-specular reflection geometries. This technique can be utilized for stand-off material characterization using the THz reflection spectroscopy in uncontrolled environments and potentially can be adopted for other broadband spectroscopic modalities.

Crystallographic and micro-structural investigations in C-phase spinels of CuFe2O4 synthesized through C12H22O11.H2O mediation

Nanocrystalline CuFe2O4 was synthesized through stotiometric mixing of aqueous solutions of Cu(NO3)2. 3H2O and Fe(NO3)3. 9H2O mediated by α-Lactose monohydrate (C12H22O11.H2O) as reductant. Aqueous NaOH solution was used as the catalyst and the reaction was carried out at room temperature. The ageing of crystallites in cubic spinel structure was accomplished by annealing the powder sample at 600 °C for 4 h. The crystallographic structure, size, strain, density, lattice parameters, inversion parameter, cation distribution, mechanism of formation, the phase homogeneity and hydrophilic behavior of the sample were studied through methods such as X-ray diffraction pattern analysis techniques, rietveld profile refinement of XRD pattern and FTIR measurements. FESEM images provided an insight into the micro-structural orientations in the formation of the sample. The semiconducting behavior and the direct band gap of 3.21 eV were estimated from Tauc’ plot employing Kubelka-Munk function for the reflectance data recorded through UV–vis spectroscopy. Further, based on the value of inversion parameter, the magnetization of the sample is predicted to be low and assumed to be in superparamagnetic regime at room temperature.
