Fluorine incorporation into silicate glasses is important for technical fields as diverse as geophysics, extractive metallurgy, reconstructive dentistry, optical devices, and radioactive waste management. In this study, we explored the structural role of fluorine in alkaline alumino-borosilicate glass, with increasing amounts of fluorine up to 25 mol % F while maintaining the glass composition. Glasses were characterized by X-ray diffraction (XRD), Al and F magic angle spinning nuclear magnetic resonance (MAS NMR) spectroscopy, and electron probe microanalysis.

The objective of this study was to assess the effectiveness of SC CAS+IMD versus no antibody treatment among patients with COVID-19.
Methods: This retrospective cohort study linked Komodo Health and CDR Maguire Health and Medical data.
species are indigenous to the marine and estuarine environments around the world and are the leading cause of water- and seafood-borne illnesses due to conditions favoring the transmission and growth of the species. Horizontal gene transfer, recombination, and mutation enable spp. to adapt rapidly to environmental challenges from biotic and abiotic parameters, including temperature, salinity, and nutrient status of the coastal waters.
