Cryo-TEM of Polyelectrolyte-Micelle Complexes
Cryo-TEM was carried out on samples containing polyelectrolyte-micelle complexes, formed by combining poly(diallyldimethylammonium chloride) (PDADMAC), a strong cationic polyelectrolye, with oppositely charged mixed micelles of sodium dodecyl sulfate (SDS) and nonionic Triton X-100 (TX100), in 0.40 M NaCl. Complexation appears to involve the formation of micelle-rich regions, presumably within ...

متن کاملCryo-TEM and AFM for the characterization of vesicle-like nanoparticle dispersions and self-assembled supramolecular fatty-acid-based structures: a few examples
The considerable development of nanosciences and nanotechnologies which now form part of our daily life requires characterization methods that are specifically adapted to enable both a high resolution and good preservation of the nanoobjects as from their preparation for analysis, especially when organic elements and water are involved in their structure. Cryo-TEM of vitreous thin films is know...
متن کاملDirect observation of liquid crystals using cryo-TEM: specimen preparation and low-dose imaging.
Liquid crystals (LCs) represent a challenging group of materials for direct transmission electron microscopy (TEM) studies due to the complications in specimen preparation and the severe radiation damage. In this paper, we summarize a series of specimen preparation methods, including thin film and cryo-sectioning approaches, as a comprehensive toolset enabling high-resolution direct cryo-TEM ob...
متن کاملImaging Extended Defects by TEM
In this invited talk, I will suggest where we are in our use of TEM for imaging extended defects and guess where we are going. Since the topic of this Symposium concerns advances in imaging and quantification of strain, local atomic structure, and the chemistry of extended defects, the present talk will emphasize the history and development of diffraction contrast methods for the analysis of ex...
