Article Synopsis
  • The study investigates acrylic polymer composites made with varying weight ratios of cement or silica nanoparticles (1, 3, 5, and 10 wt%) to evaluate their effects on mechanical, dielectric, thermal, and hydrophobic properties.
  • Composites with 5 wt% nanoparticles showed the best performance, exhibiting low abrasion wear, high hardness, and strong impact resistance, while cement composites outperformed silica composites due to their particle size and conductivity.
  • Surface treatment with dielectric barrier discharge (DBD) plasma jet significantly improved the hydrophobicity of the composites, increasing water contact angles notably, making DBD treatment an effective and low-cost method for enhancing these properties in material coatings for various applications.

Introduction:  Effective medications are becoming more necessary to combat the global rise in antimicrobial resistance. The findings that some flavonoids have antibacterial properties have urged interest in flavonoid research. The aim of this work was to investigate the inhibitory properties of fisetin, fisetinidin, 7,3`,4`-trihydroxyflavone (THF), and 7,3`,4`-trihydroxyflavonol (THF-) against selected pathogenic bacteria and fungi and to review the literature on relevant compounds.

The prevalence of organophosphate esters (OPEs) in the global environment is increasing, which aligns with the decline in the usage of polybrominated diphenyl ethers (PBDEs). PBDEs, a category of flame retardants, were banned and classified as persistent organic pollutants (POPs) through the Stockholm Convention due to their toxic and persistent properties. Despite a lack of comprehensive understanding of their ecological and health consequences, OPEs were adopted as replacements for PBDEs.

Breast cancer is a leading cause of cancer-related morbidity and mortality worldwide, with the highest incidence among women. Among the various subtypes of breast cancer, estrogen-receptor positive (ER+) is the most diagnosed. Estrogen upregulates cyclin D1, which in turn promotes the activity of CDK4/6 and facilitates cell cycle progression.
