Chemistry and Pharmacokinetics of Gallium Maltolate, a Compound With High Oral Gallium Bioavailability [PDF]
Gallium maltolate, tris(3‐hydroxy‐2‐methyl‐4H‐pyran‐4‐onato)gallium (GaM), is an orally active gallium compound for therapeutic use. It is moderately soluble in water (10.7 ± 0.9 mg/mL at 25 ∘C) with an octanol partition coefficient of 0.41±0.08. The molecule is electrically neutral in aqueous solution at neutral pH; a dilute aqueous solution (2.5 ×10 ...

X-parameter modelling of GaN HEMT based on neural network
Currently, S-parameters are commonly used in the design, measurement, and modelling of microwave circuits, but it is only suitable for linear small-signal conditions and not suitable for large-signal conditions.

900 V GaN-based sine-wave inverters for three-phase industrial applications
GaN devices are gradually getting attention within the industry along with SiC as a potential wide bandgap device. At present, there are almost no high-voltage GaN devices with voltage >650 V, which makes an inverter design difficult for a three-phase ...
