China announced the restrictions on gallium and another mineral, germanium, in a move seen as part of the country’s tit-for-tat trade war on technology with the US and Europe.

Astronomers from the University of Turku in Finland and elsewhere have performed a broadband spectral and timing study of an ...

In computational proteomics, the peptide identification via interpreting its tandem mass spectrum is an important issue. The classification of b and y ions in the spectrum plays a vital role for ...

In this paper, we discuss the phenomenon of pulse recovery in overdriven low noise amplifiers fabricated with Gallium Nitride technology. We present our experimental set up to determine the pulse ...

Collaboration has obtained a high-precision cosmic-ray boron spectrum in the energy range of 10 GeV/n–8 TeV/n, and discovered ...

The performance of mass spectrometers with limited pumping capacity is shown to be improved through use of a discontinuous atmospheric pressure interface (DAPI). A proof-of-concept DAPI interface was ...
