TL;DR: In this article, a self-aligned technique was developed to pattern the extraction gate, insulator, and nanotubes in the micro-cathode, which exhibited a peak current of 105 μA at 48 V when operated with a duty cycle of 5% and an average current of 0.5 µA when operated at 48V.

TL;DR: The similarities between the experimental and observed absorption spectra indicate that carbon onions are very strong candidates for the origin of the UV interstellar absorption peak at 4.6 microm(-1), a key feature of the interstellar spectrum.

TL;DR: In this article, the electrical properties of individual carbon nanotubes were investigated for designing field emission devices and the failure of nanotube under field emission was also discussed, showing that the field enhancement of the structures is strongly related to the geometry (height/radius) of the structure and maximum emission currents of ∼10 μA were obtained.

TL;DR: The μ-sieving technique was applied to the separation of cancer cells (MDA-MB-231) from whole blood and it was shown that the fluidic oscillations prevented the filters from being blocked by the filtered cancer cells allowing continuous microfluidic separation with high efficiency.

TL;DR: This study obtained highly crystalline SnS thin films by atomic layer deposition and obtainedhighly crystallineSnS2 thin filmsBy phase transition of the SnSthin films, and compared the film characteristics of these two tin sulfide thin films and their switching device characteristics.
