Hydrophobic, fluorinated silica xerogel for low-k applications.
… species. Films from triethoxyfluorosilane (TEFS) have been shown to be promising interlayer dielectric materials for future integrated circuit applications due to their low dielectric constant and high mechanical properties (i.e., Young's modulus (E) and hardness (H)). Co-condensing with …

Characterizaton of Triethoxyfluorosilane and Tetraethoxysilane Based Aerogels
… feature sizes. Precursors triethoxyfluorosilane (TEFS) and tetraethoxysilane (TEOS) were used to prepare bulk aerogels. Samples were prepared by sol-gel methods, and then carbon dioxide supercritically-dried. Effects of varying the water to precursor ratio were studied with respect to aerogel …

Monitoring of atmospheric polycyclic aromatic hydrocarbons through optimization of analytical techniques
… using selected Toxic Equivalence Factors (TEFs). From an overall analysis of household cooking fuel use in coastal Kenya, gas stoves were found to account for the least (0%) PAH emissions (no detected carcinogenic contribution) in indoor setups. Average BaPeq total concentrations for …
