  • Patent number: 11561209
    Abstract: A method for simultaneous determination of nitrogen and oxygen isotope compositions of natural nitrate and nitrite, which quantitatively converts natural nitrate and nitrite into an organic ester and a nitro-compounds respectively, and then nitrate and nitrite ?18O and ?15N are simultaneously determined by adopting a gas chromatography/pyrolysis/gas chromatography/isotope ratio mass spectrometry coupling technology (GC/Py/GC/IRMS). According to the method for simultaneously determining the nitrogen and oxygen isotope compositions of the natural nitrate salt and nitrite salt, the small amount of sample does not result in the loss, acquisition, exchange and fractionation of nitrogen and oxygen.

  • Patent number: 11402893
    Abstract: Described is an apparatus comprising a first interface, a second interface, a third interface, and an interconnection fabric. The first interface may transfer a first stream of data traffic. The second interface, which may be an enhanced Serial Peripheral Interface (eSPI) interface, may transfer a second stream of data traffic and a third stream of data traffic. The third interface may transfer a fourth stream of data traffic. The interconnection fabric may couple the first interface to the second interface and may couple the second interface to the third interface. The second interface may initiate a transfer of an outbound data stream from one of the second stream of data traffic or the third stream of data traffic based on an available-space credit indicator. The second interface may receive an inbound data stream based upon the outbound data stream.
