Imaging of Self-Assembled Structures: Interpretation of TEM and Cryo-TEM Images [PDF]

open access: yesAngewandte Chemie - International Edition, 2010
AbstractThe investigation of solution‐borne nanostructures by transmission electron microscopy (TEM) is a frequently used analytical method in materials chemistry. In many cases, the preparation of the TEM sample involves drying and staining steps, and the collection of images leads to the interaction of the specimen with the electron beam.

TEM-based cathodoluminescence of a Selenium-alloyed CdTe solar cell

open access: yes, 2021
Since 2015, commercial sample holders have been available that enable cathodoluminescence imaging of semiconductors in the TEM. Despite this, issues with low signal have meant that high resolution TEM-CL imaging has so far not been achieved on a solar ...

Sequences of the Genes for the TEM-20, TEM-21, TEM-22, and TEM-29 Extended-Spectrum β-Lactamases [PDF]

open access: yesAntimicrobial Agents and Chemotherapy, 1999
ABSTRACT The sequences of the bla TEM genes encoding TEM-20, TEM-21, TEM-22, and TEM-29 extended-spectrum β-lactamases were determined. Analysis of the deduced amino acid sequences indicated that TEM-20 and TEM-29 were derived from TEM-1 and that TEM-21 and TEM-22 were derived from TEM-2.
