Polydioctylfluorene (PFO) can be found in liquid-crystalline, glassy, amorphous, semi-crystalline or β-chain formation. This variety is on account of the intermolecular forces that PFO can participate in. The secondary forces present in PFO are typically van der Waals, which are relatively weak. These weak forces makes it a solid that can also ...

All deer except the one with elevated levels at Clark's Marsh were found to have no or very low levels of PFAS ...
