Application


  • Light-Emitting-Diode-Induced Fluorescence from Organic Dyes for Application in Excitation-Emission Fluorescence Spectroscopy for Food System Analysis.: This study leverages the use of barium sulfate as a component in fluorescence spectroscopy for analyzing food systems. The research demonstrates how barium sulfate can enhance the fluorescence properties of organic dyes, making it a valuable tool in food safety and quality control (Vladev et al., 2024).

  • Analytical methods for quantitating sulfate in plasma and serum.: This article outlines new analytical techniques for quantifying sulfate in biological samples, with barium sulfate playing a crucial role in the precipitation and measurement processes. These methods improve the accuracy and reliability of sulfate quantitation in clinical and biochemical research (Vijayakumar and Dawson, 2024).

  • Comparison of micro-CT image enhancement after use of different vascular casting agents.: This study compares various vascular casting agents, including barium sulfate, to enhance micro-CT imaging. The findings indicate that barium sulfate significantly improves the visualization of vascular structures, making it a superior choice for detailed anatomical studies (Margolis et al., 2024).

  • Development of Lead-Free Radiation Shielding Material Utilizing Barium Sulfate and Magnesium Oxide as Fillers in Addition Cure Liquid Silicone Rubber.: This research presents a novel radiation shielding material that uses barium sulfate as a key filler. The study highlights the material′s effectiveness in providing radiation protection while being environmentally friendly and lead-free (Souza et al., 2023).
