Sodium carbonate and diboron trioxide obtained from Alfa Aesar, MA, USA with 99.99% purity was mixed with powdered CeO2 of 99.9% purity to create a series of Na2O·2B2O3·xCeO2 glasses with x = 0.01–0.6 mol as shown in Table 1 . The glass compositions containing 0.05 mol of CeO2 were then melted at different temperatures and times with different raw materials such as sodium tetraborate deca-hydrate to observe changes in Ce3+/Ce4+ ratios due to melting parameters. Each of these compositions were melted in a platinum crucible using a high-temperature furnace in air atmosphere and quenched between two steel plates to achieve a fast-cooling rate to prevent crystallization. Each sample was then processed to a fine powder using a Retsch Mixer Mill MM 500-Nanomill and stored in a desiccator cabinet.

Total polyphenol contents were estimated following the Folin-Ciocalteu method of Baba and Malik [18 (link)] with some modifications. Ten microliter sample was mixed with 150 μL of distilled water in 96-well microplate and mixed thoroughly with 25 μL Folin-Ciocalteu reagent (Sigma-Aldrich Corp., St. Louis, MO, USA) for 3 min. Then, the mixture was added to 100 μL 20% (w/v) sodium carbonate (Ajax Finechem, Auckland, New Zealand) and allowed to incubate at room temperature for 60 min in the dark. The absorbance of blue-complex was measured at 650 nm using a microplate reader (Tecan Sunrise, Männedorf, Switzerland). Gallic acid monohydrate (125, 250, 500, 750, 1000 μL/mL; Sigma-Aldrich Corp.) and deionised water were used as standard and blank, respectively. The total polyphenol contents of samples were expressed as milligram of gallic acid equivalents (GAE) in 100 g sample.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
