It is well known that the microstructure of electrodes in lithium‐ion batteries has an immense impact on their overall performance. The compaction load during the calendering process mainly determines the resulting morphology of the electrode. Therefore, NCM‐based cathode films from uncompa...
Energy‐dispersive X‐ray mapping in a scanning transmission electron microscope is a method to visualize the spatial distribution of chemical elements in a sample. Quantification of the signal intensities depends on proper background elimination and correction of the self‐absorption and fluo...
Due to the large slope and complex geometry, it is difficult to measure the three‐dimensional parameters of cutting tools and drill bits by using general optical measurement method. A method that combines the multiview rotation scanning and nonmechanical focus variation by using a liquid le...
Two‐photon microscopy (2PM) offers great potential in fluorescence imaging of intracellular Na+ dynamics of live cells. A severe drawback, however, is that quantitative ratioing of fluorescence intensities at different wavelengths [possible in one‐photon imaging with the classical Na+‐indic...
In this paper, we propose and demonstrate an improved fluorescence emission difference microscopy (FED) method, exploiting programmable phase modulation for image enhancement. The main novelty of the proposed approach lies in the matched size and intensity of two excitation spots. The propo...
