چکیده
The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. New TEM grids coated with ultrathin amorphous Al 2 O 3 films have been developed using atomic layer deposition technique. The amorphous Al 2 O 3 films can withstand temperatures over 600 • C in air and 900 • C in vacuum when the thickness of the Al 2 O 3 film is 2 nm, and up to 1000 • C in air when the thickness is 25 nm, which makes heating TEM grids with nanoparticles up to 1000 • C in air and immediate TEM observation without interrupting the nanoparticles possible. Such coated TEM grids are very much desired for applications in high-temperature high-resolution transmission electron microscopy.

The acid oxidation of carbon nanotube generally results in opening the close ends of the nanotube and to make surface modifications. Herewith, Multiwall carbon nanotubes (MWCNTs) were oxidized in acids at high temperature experimental conditions which led to the formation of graphene quantum dots (GQDs). High resolution transmission electron microscope (HRTEM), energy dispersive X-ray spectro...

In this paper a new phase-frequency detector is proposed using transmission gates which can detect phase difference less than 500ps. In other word, the proposed Phase-frequency Detector (PFD) can work in frequencies higher than 1.7 GHz, whereas a conventional PFD operates at frequencies less than 1.1 GHz. This new architecture is designed in TSMC 0.13um CMOS Technology. Also, the proposed PFD a...
