FM-AFM imaging of a commercial polyethylene film immersed in n-dodecane.

The subnanometer topography of a partially crystalline polyethylene film was observed in liquid n-dodecane using a frequency-modulation atomic force microscope. Locally ordered structures were found and assigned to a (100) facet of crystalline domains.

A self-assembled helical anthracene nanofibre whose P- and M-isomers show unequal linear dichroism in a vortex.

An anthracene derivative, having benzamide substituents bearing optically active alkyl chains, in hexane forms one-handedly biased helical supramolecular nanofibres, which show unequal linear dichroism (LD) in right- and left-handed vortex flows.
