The role of iron(III) hydroxide as a collector of
Iron (III)hydroxide formed in sea water possesses a charge which is pH-dependent. At pH 4.0 the colloid has an apparent maximum positive-charge density and is able to adsorb molybdenum quantitatively as molybdate. Above pH 9 the charge is reversed and the iron (III) hydroxide no longer collects molybdate.
Molybdenum(IV) oxide 99 1
Molybdenum (IV) oxide (MoO 2) is a transition metal oxide with good electrical conductivity due to the presence of delocalized electrons in its valence band. It is traditionally prepared by reducing MoO 3 in dry hydrogen in the temperature range of 450-550°C. [ 1]

DMSO
Pour une application topique, une dilution de 40 à 80 % de DMSO dans de l'eau pure est nécessaire pour obtenir un effet. Pour certains états pathologiques, la dose est plus faible, tandis que pour d'autres, elle est plus élevée. Cela dépend de la quantité d'eau nécessaire pour que le DMSO pénètre dans les tissus.

Is there a difference between polarity and hydrophobicity?
If the result is greater than 1.7 the bond is generally considered ionic. Water is polar. because oxygen (3.5) is more electronegative than hydrogen (2.2) and the difference (1.3) is between 0.4÷1.7. So the oxygen has a slight negative charge, while the hydrogens have slight positive charges in water.

Eintrübung einer hydrophilen Intraokularlinse nach multiplen
Für Eintrübungen hydrophiler Linsen sind in der Literatur verschiedene Ursachen beschrieben. Ausgeprägte Trübungen sind eine ernst zu nehmende Komplikation, da sie bis zur Explantation bzw. bis zum Austausch der Intraokularlinse (IOL) führen können. Die Kalzifizierung hydrophiler IOLs wird häufig für die Explantation verantwortlich gemacht.
