Transmission electron microscopy (TEM) is an important and versatile method for investigating materials on the nanoscale. Information about the elemental composition and electronic structure can be obtained while imaging the sample with atomic resolution. Such investigations are usually performed by TEM-experts. However, enabling non-expert TEM users to perform such measurements would tremendously improve the efficiency of TEM investigations in both, materials science and chemistry. We therefore developed ChemiTEM: a set of standardized workflows for data acquisition and analysis which are integrated in an app for tablets and smartphones to provide easy access for all TEM users, irrespective of their level of experience. We tested the ability of ChemiTEM in helping non-expert TEM users to collect high quality data by having non-expert and expert TEM users investigate the same sample. Using ChemiTEM, the data acquired by the non-expert users were of similar quality to that of the data recorded by the TEM-expert. Thus, we were able to show that using the ChemiTEM app, TEM can be made available to everyone working in materials science.
