WitrynaRutile-type titanium oxide (TiO2) is a resource-rich and inexpensive material with a one-dimensional ion-diffusion path along the c-axis. However, it has received no attention as an anode material for Na-ion batteries because of its low electronic conductivity and limited ion diffusion in the ab-plane direction. We have revealed for the first time the … Witrynafor a safety assessment for . the parenteral . and . or inhalation. route of administration, modifying factors based on oral bioavailability were used to derive the PDE from the oral PDE: Oral bioavailability <1%: divide by a modifying factor of 100; Oral bioavailability ≥ 1% and <50%: divide by a modifying factor of 10
