Glycine, being a naturally occurring amino acid, serves as a sustainable, renewable, and low-emission alternative to conventional fuels, minimizing the environmental impact of the synthesis process. The research focuses on analyzing Judd–Ofelt (JO) parameters to explore the luminescent properties and optical performance of the nanophosphors, with a specific emphasis on their application in near-ultraviolet (UV) light-emitting diodes (LEDs). The combustion method employed produces nanophosphors with exceptional optical characteristics while reducing both energy consumption and harmful emissions. The study includes the synthesis process, structural characterization, and photoluminescence analysis of the LiGd₂₋ₓYₓ:Eu3+O₃ nanophosphors. By applying JO theory, the JO parameter analysis provides valuable insights into the luminescent behavior, enabling the optimization of optical properties for improved performance in near-UV LED applications. The findings highlight the importance of JO parameter analysis in refining the luminescent efficiency of these nanophosphors. Moreover, the use of the combustion technique promotes the development of innovative materials for next-generation optoelectronic devices. This work contributes to the understanding of nanophosphor synthesis and offers potential solutions for energy-efficient, environmentally friendly lighting, addressing the increasing demand for sustainable technologies in lighting and optoelectronics.\u0000 </div>","PeriodicalId":49902,"journal":{"name":"Luminescence","volume":"40 3","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143622628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a highly selective, tumor-agnostic agent which has been approved in both adult and pediatric patients. Three different analytical methods for estimation of such important drug were developed. Two simple spectrophotometric methods were developed: Method I involves measuring the absorbance of different concentrations of the larotrectinib at 264 nm in concentrations ranging from 2 to 15 μg/mL in ethanol while first derivative peak amplitude (Method II) was derived and measured at 278 nm in concentration ranges from 2 to 15 μg/mL. A spectrofluorimetric technique was carried out by creating an ion pair complex through the interaction of larotrectinib with eosin Y in the presence of a Britton–Robinson buffer at pH 3.5. The fluorescence quenching of the resulting complex was then detected at 535 nm as the emission peak following excitation at 265 nm. The spectrofluorimetric technique exhibited high sensitivity and linearity across concentration ranging between 0.5 and 10 μg/mL. These three methods were effectively utilized to quantify larotrectinib in both its raw form and its pharmaceutical formulation. Greenness of the developed methodologies was concerned and evaluated via three different tools including analytical ecoscale, green analytical procedure index (GAPI), and analytical greenness metric approach (AGREE).\u0000 </div>","PeriodicalId":49902,"journal":{"name":"Luminescence","volume":"40 3","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143594911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It develops various diseases through increasing intracellular ROS that interacts with vital organs. Chelation therapy is currently recommended for arsenic toxicity. However, these treatment options are not specific and only target symptoms. Besides, they also show toxic effects and irreversibly damage crucial organs. Hence, there is an urgent need for a potential and safer therapeutic strategy that can prevent arsenic toxicity. Therefore, in this study, we have investigated SA and EC individually and in combination against arsenic toxicity in HCT-116 cells. The results obtained from various experiments revealed that both plant materials comparably inhibited arsenic-induced cellular damage by increasing the antioxidant function. Conversely, combining both plants showed even better cytoprotection against arsenic toxicity. The FT-IR and HPLC analysis of the active fractions revealed the presence of polyphenol compounds (ferulic acid and gallic acid) responsible for the pharmacological effect.

Herein, we report the first direct, label-free spectrofluorometric method for simultaneously quantifying methocarbamol (MET) and aspirin (ASP) in coformulated tablets and spiked human urine. The method utilizes excitation at 274 nm with independent emission detection at 300 nm for MET and 402 nm for ASP, using methanol as the diluting solvent. The assay was rectilinear over ranges of 0.10–0.80 μg/mL for MET and 0.05–0.50 μg/mL for ASP with detection limits of 14.9 and 10.6 ng/mL for MET and ASP, respectively. The method was validated in compliance with ICH regulations. The approach was applied efficiently to assay both analytes in their tablets and spiked human urine with high % recoveries (98%–103%) and low RSD (1.7%–3.3%). In addition, the sustainability and practicality of the developed method were assessed using the RGB-12 whiteness algorithm, indicating the whiteness of the developed method.
