The hole current due to recombination in the N epitaxial layer is calculated and compared to the electron current injected into the diffused P region. A formula is given and results are compared with ...

Scanning electron microscopy (SEM) is of great significance for analyzing the ultrastructure. However, due to the requirements of data throughput and electron dose of biological samples in the imaging ...

Teaching the VSEPR (valence shell electron-pair repulsion) model can be a tedious process. Traditionally, Lewis structures are drawn and the number of “electron clouds” (groups) around the central ...

ZnO/Zn(OH)2 nanosheets on copper foil enhance lithiophilicity and stabilize lithium metal anodes for improved cycling ...

However, no electron density was seen for an unusual 130 Å-long coiled-coil domain predicted by AlphaFold2. When that was replaced by a short linker, the researchers were able to determine a 3.0 Å ...

Another cryo-electron microscope structure of MmpL4 bound to desferrated mycobactin identified the precise binding site for mycobactin on the cytosol-exposed region of MmpL4, ...
