Field effect transport properties of chemically treated graphene quantum dots

We report the field effect properties of lithographically fabricated FET with as–prepared graphene quantum dots (GQDs) and hydrazine treated GQDs as channel material. GQDs of 4.5 ± 0.55 nm average diameter are synthesised via an electrochemical approach using multiwalled carbon nanotubes (MWCNTs) as precursor. After treatment in hydrazine vapour for 24 h, the field effect measurements yield hole ...

Honeywell gas detectors serve emergency backup role in U.S. rocket launch to destroy spy satellite

A U.S. Standard Missile 3 (SM-3) enabled by Honeywell technology recently shot down a rogue U.S. spy satellite in space carrying over 1000 pounds of hydrazine, a highly toxic chemical used in rocket ...

Aerojet Rocketdyne Successfully Completes Qualification Tests on Reusable Engine to Support Next Era of Human Spaceflight from the United States

Aerojet Rocketdyne, Inc., a subsidiary of Aerojet Rocketdyne Holdings, Inc. (NYSE:AJRD), has successfully completed hot-fire qualification tests of an engine that demonstrates the ability to meet reusability requirements for Boeing`s Crew Space ...

Oxygen Scavengers for Water Treatment Chemicals

Oxygen scavenging means preventing oxygen from introducing oxidation reactions. Most of the naturally occurring organics have a slightly negative charge. Due to that they can absorb oxygen molecules, because these carry a slightly positive charge, to prevent oxidation reactions from taking place in water and other liquids. Oxygen scavengers include both volatile products, such as hydrazine (N2H4) ...
