Abstract: Gyrotron traveling wave amplifiers (Gyro-TWA) have both the characteristics of high power and broadband, which have wide application prospects in many important military fields, such as ...

Reshaping graphene from flat sheets into compact particles solves a key manufacturing problem, enabling printable conductive ...

Abstract: A multibeam-based traveling wave tube (TWT) system aims to concurrently amplify multiple RF sources with a compact size. However, the practical implementation of this multibeam-based TWT ...

The graphene hype has faded while graphite demand is surging. U.S.–China tensions are reshaping graphite markets, with punitive U.S. tariffs on Chinese anode-grade graphite boosting investor interest ...

Following the Nobel Prize for graphene's discovery in 2010, the gee-whiz nanomaterial has been lauded as a "wonder material" with endless theoretical applications, including graphene super batteries, ...

Graphite mines in the United States largely closed down seven decades ago. Mining the ubiquitous mineral found in everything from nuclear reactors to pencils seemed to make little sense when it could ...

During the past 30 days the China graphite flake-194 EXW spot price was flat. The China graphite flake +195 EXW spot price was flat. Note that 94-97% is considered best suited for use in batteries; it ...
