Molecularly specific detection towards trace nitrogen dioxide by utilizing Schottky-junction-based Gas Sensor

Here, trace detection of NO2 is achieved with a 2D Schottky-junction Bi₂O₂Se gas sensor. Simultaneous signals allow for detection in the ppt range, and impedance angle analysis allows for molecular specificity.

Robust ultraclean atomically thin membranes for atomic-resolution electron microscopy

High-resolution electron microscopy requires robust and noise-free substrates to support the specimens. Here, the authors present a polymer- and transfer-free direct-etching method for fabrication of graphene grids with ultraclean surfaces and demonstrate cryo-EM at record high resolution.
