Quantitative analysis of electron microscope images of organic and biological two-dimensional crystals has previously shown that the absolute contrast reached only a fraction of that expected theoretically from the electron diffraction amplitudes. The accepted explanation for this is that irradiation

A liquid helium-cooled cryoelectron microscope, operated to expose the specimen to only a very low electron dose, was used to obtain structural images of monolamellar n-tetratetracontane (n-C44H90) crystals at 0.25-nanometer resolution. These results are in contrast to earlier predictions that

The encapsulation of pentacene thin-film transistors (TFTs) by a 50 nm thick layer of a long chain alkane (C₄₄H₉₀) enables the operation in an aqueous solution of 1 mM NaCl. It is the first time that pentacene TFTs operate successfully
