The growing demand for clean energy and the urgent need to reduce carbon emissions have accelerated development of alternative solutions, with solid oxide electrochemical cells standing out due...
Carbon quantum dots (CQDs) are known for their intriguing optical properties, low toxicity, and high biocompatibility, which make them promising biomedical applications. In this study, CQDs were synthesized by subjecting orange juice to microplasma as a carbon source at atmospheric pressure temperatures. The resulting exhibited narrow size distribution, with an average diameter of approximately 4.5 nm pH value 5.67. These strong blue emission characteristics. antibacterial properties the...
TLC-SERS analysis of PDE-5 inhibitors adulterated in herbal products.
ABSTRACT Chemical drugs illegally added to herbal products result in prominent health risks for users, especially frequent users of dietary supplements. Onsite detection pharmaceutical compounds adulterated is crucial ensuring product quality and safety. In this study, an efficient method that integrates thin‐layer chromatography (TLC) with dynamic surface‐enhanced Raman spectroscopy (DSERS) the analysis simultaneous adulteration paracetamol chlorpheniramine maleate was developed. Silver...
Green carbon quantum dots (CQDs) were fabricated through microplasma-liquid interactions, involving the treatment of an orange juice solution at atmospheric pressure and room temperature. Morphological analyses CQDs revealed a spherical shape with average size approximately 2.5 nm. The emission peak wavelength 440 nm was observed for blue emissive CQDs, excitation 350 exhibited excellent luminescence activity, dependent on wavelength, shifting towards longer wavelengths. Raman spectrum...
Abstract We prepared Ba 3− x Y Co 2 Fe 24 O 41 (Y‐Co Z, = 0, 0.2, and 0.4) by the solid‐state reaction method. Y‐Co Z polyaniline (PANI) composites (named as Y‐P0, Y‐P2, Y‐P4) were using in‐situ polymerization The Y‐doping played an important role in variation of lattice parameters, a c . combination PANI modified magnetic properties composites, which could be observed changing saturation magnetization coercivity. This had also affected electromagnetic through measurements complex...

This study presents a DAD-HPLC method developed for the simultaneous detection of histamine H1 antagonist drugs and analgesic compounds, including paracetamol, cetirizine hydrochloride, cinnamazine, chlorpheniramine maleate, loratadine, in herbal formulations. systematically investigates critical parameters enhancing separation quantification using DAD-HPLC. Chemometric techniques were employed to optimize detecting adulterants, with sample preparation involving liquid-phase extraction...
Abstract Carbon quantum dots (CQDs), synthesized through controlled microplasma treatment of orange juice, exhibit unique luminescent characteristics. The impact synthesis time on particle size was investigated. Deconvoluted emission spectra displayed broad bands, peaking at an excitation wavelength 350 nm for CQD sizes 2.06, 2.4, and 3.09 nm, indicating multiple fluorescence peaks. This suggests a mixture CQDs with different energies their surfaces. Luminescence kinetics unveiled three...
