    Asian Journal of Pharmaceutical and Clinical Research, 2025
    Objectives: A novel, speedy, and accurate high-performance liquid chromatography approach has been established for quantitatively analyzing lobeglitazone sulfate and glimepiride. Methods: In this method, the drugs were separated using Inertsil Octadecylsilyl (ODS) 250 × 4.6 mm, 5 μm column with a flow rate of 1 mL/min. The buffer consists of 1 mL of formic acid, which is dissolved in 1 L Milli-Q water, and a mobile phase consisting of a 50:50 (v/v) mixture of 0.1% formic acid and acetonitrile. The 260 nm wavelength was used for detection. Results: Lobeglitazone sulfate concentrations ranging from 12.5 μg/mL to 75 μg/mL and glimepiride concentrations from 25 μg/mL to 150 μg/mL show good linearity in the suggested approach. The limit of detection and limit of quantification values were 0.3 μg/mL, 1.0 μg/mL and 0.15 μg/mL, 0.5 μg/mL for glimepiride and lobeglitazone sulfate, respectively. All the parameters of accuracy, specificity, and method precision were all within the acceptable limit. Conclusion: In the forced degradation studies, the degradation products were characterized by the use of liquid chromatography–mass spectrometry. The current method was found to be simple, economical, suitable, and validated according to the International Council for Harmonization guidelines.
  • Synergistic Influence of Ni Substitution on Synergistic Influence of Ni substitution on Structural, Magnetic and Photocatalysis Properties of Y0.85La0.15FeO3 Nanomaterials
    Kalakonda Sajini, Rama Sekhara Reddy Dachuru, Gudela Krishnaveni
    Ecs Journal of Solid State Science and Technology, 2025
    Y0.85La0.15Fe1−x Ni x O3 (where 0 ≤ x ≤ 0.15) nanomaterials were fabricated via sol-gel method. The structural characterization and estimation of crystallite size of synthesized nanopowders were performed using X-ray powder diffraction (XRD) and scanning electron microscopy (SEM), respectively. However optical band gap and magnetic behavior of these nanopowders were estimated using UV–vis absorption and Vibrating-sample magnetometer (VSM). An orthorhombic structure with pure phase for the synthesized samples (for x = 0, 0.05, 0.10 and 0.15) was observed through XRD analysis. The calculated tolerance factor was increased from 0.8132 to 0.8411 with an increase of Ni2+ concentration from 0 to 15 mol % in Y0.85La0.15Fe1-x Ni x O3. Due to electronic transitions of valence band (2p level of oxygen) to conduction band (3 d level of iron), the p-d transition was observed in range of 500 to 600 nm using the UV–vis absorption spectrum. Due to decrease of crystallite size from 125 nm to 108 nm, an increased optical band gap from 1.98 eV to 2.06 eV was noticed in the synthesized samples. The enhanced saturation magnetization (Ms) value was observed for Y0.85La0.15Fe0.85Ni0.15O3 nanomaterials when compared to that of other samples in this study. The Ni ion doped at Fe site leads to the variation of oxidation state in Fe atom as a consequence increase of super exchange interaction Fe3+-O2—Fe2+, Y3+/La3+-O2−-Fe3+/Fe2+, Fe3+/Ni2+-O2− -Fe3+/Fe2+, Y3+/La3+-O2−- Ni2+ compared to that super exchange interaction of un-doped YFeO3 sample. X-ray photoelectron spectroscopy (XPS) technique was employed to determine the oxidation state of each atom in the sample. Rate constant k obtained for x = 0 and x = 0.15 were found to be 0.0083 min−1 and 0.0132 min−1 respectively. In summary, the obtained result indicates that Ni substitution at Fe site is greatly influenced on structural and physical properties of Y0.85La0.15FeO3 nanomaterials.

    Herein, the structural, optical, and magnetic properties of Y0.85La0.15FexAlyO3: (x; y) where x = 1; y = 0, x = 0.975; y = 0.025, x = 0.95; y = 0.05, and x = 0.9; y = 0.1 nanomaterials obtained from sol–gel method are reported. The X‐ray powder diffraction (XRD) for the structural characterization, scanning electron microscopy for crystallite size estimation, ultraviolet–visible absorption for optical studies, and vibrating‐sample magnetometer for magnetic studies are used in this investigation. An increase of orthorhombic crystal structure with an increase of Al content in the sample is observed from XRD studies. The existence of all the elements present in the samples is observed from energy‐dispersive X‐ray spectroscopy. The optical bandgap increases from 2.04 to 2.10 eV with an increase of Al concentration from 0 to 0.05. The observed magnetization value is 3.14 emu g−1 for y = 0.05, which is higher than y = 0 (2.11 emu g−1) and y = 0.024 (2.58 emu g−1). In summary, the obtained result (x = 0.95; y = 0.05) can be useful for different magnetic‐based applications.
  • Structural and Magnetic Properties of Y0.85La0.15Fe1−(4/3)xTixO3 (where (x = 0, 0.025, 0.05 and 0.075) Nanomaterials Derived from Sol-Gel Route

    Y0.85La0.15Fe1−(4/3)xTixO3 (where (x = 0, 0.025, 0.05 and 0.075) nanomaterials were prepared using tartare acid assisted sol-gel method. Various analytical characterization techniques such as X-ray powder diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), UV–vis absorption, Vibrating-sample magnetometer (VSM) and dielectric spectroscopy were employed to characterize the synthesized nanomaterials. Downward shifted of (121) and (002) planes were observed with an increasing of Ti concentration at Fe site through XRD study. The ability of the prepared nano-powders to absorb visible light was demonstrated by the investigation of diffuse reflectance spectra, which showed a decline in bandgap from 2.13 eV to 2.06 eV. XPS studies revealed that Y and La atoms are existed in +3 oxidation state, Fe atom is existed in mixed (+2 and +3) oxidation state and Ti atom is existed in mixed (+3 and +4) oxidation state. The highest magnetization value was observed for x = 0.05 sample through VSM study. High dielectric constant, low dielectric loss and low conductivity values were also observed for Y0.85La0.15Fe1−(4/3)xTixO3 (where (x = 0.05)).

    Asian Journal of Chemistry, 2021
    Aflatoxins produced by Aspergillus flavins and Aspergillus pasasiticus have been investigated in the corn (maize) collected in different locations in Andhra Pradesh state, India. In the present study, 24 corn samples collected from different harvest, storage and dumping areas were analyzed for detection of aflatoxin contamination by liquid chromatography coupled with mass spectrometry (LC-MS). Mixed aflatoxin working standard solutions with a concentration of 10, 20, 30, 40, 50 and 60 ng/mL were prepared and followed by instrumental analysis and the retention times of the sample chromatograms were compared with the standard aflatoxins B1, B2, G1 and G2 retention times in order to determine the contamination. The findings revealed that among 24 collected samples, only 10 samples have been found positive for aflatoxins contamination when subjected to LC-MS analysis. Co-occurrence of aflatoxin was identified in the most of the samples. Even though 10 samples were tested positive total aflatoxin content in the most positive are found within the acceptable limits (30 μg/kg) and samples collected at dumping areas (S4, S8 and S10) show the presence of exceeding quantity than the limits described by FSSAI. Total aflatoxin content in the most positive were found within the acceptable limits (30 μg/kg) and the samples collected at dumping areas S4 (40.9 μg/kg), S8 (53.2 μg/kg) and S10 (71.86 μg/kg) had shown exceeding limits. The sample S7 collected from the storage was also found positive of presence of aflatoxin G2- 13.49 μg/kg and B2-21.14 μg/kg with total aflatoxin of 34.65 μg/kg. High contamination of these dumping areas may lead to contamination of storage points nearer to these areas. Present results showed that the corn samples at dumping areas were found to be contaminated with the Aspergillus flavins and Aspergillus pasasiticus.
