Using the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers observed an interstellar medium in a distant star-forming galaxy SPT0346-52. The collected data could be essential in improving ...
Discontinuous atmospheric pressure interface (DAPI), consisting of a pinch valve, a silicone tube, and two metal capillaries, is a common inlet for miniature ion trap mass spectrometers (ITMS). It can improve the transport ...
